    BRIEF DESCRIPTION OF THE DRAWINGS The invention will be described in more detail with reference to the accompanying drawings, in which: Figure 1 illustrates one example of a system for determining a driver's driving condition and ability; Figure 2 shows another example of a system for determining a driver's driving condition and ability; Figure 3 is a flow chart of a method according to an example; and Figure 4 shows a device according to an embodiment. - DETAILED DESCRIPTION The object of the present solution is to provide an apparatus, method and computer program for determining a driver-specific driving style and a driving mode identification number describing it, as well as for controlling the functions of a driving device on the basis of a driving mode identification number. This text refers to the terms “driving style” and “driving mode code (so-called Driving Behavior Index (ATI), Individual Driving Index (IDI)). Driving style refers to a driver-specific and identifiable combination - behaving and reacting to changing and / or repetitive tasks. The driving mode is thus N the “fingerprint” or “handwriting” of the driver to perform the driving situation. The driving style can be misinterpreted as “driving ability”, which mainly refers to so-called driving health. Driving health is the ability to cope physically and mentally with a driving situation. Driving ability is also reflected in pressure tolerance and judgment. Nor should I 30 - be interpreted as 'driving skills', a term referring to a routine achieved through training, learning and experience. Technical routines affecting driving skills, = speed of reaction in different and / or unexpected traffic situations, training,
    LO N game eye in traffic, authorized to act as the driver of the vehicle in question N and skillfully. The term “driving style index” refers to a numerical value for a driving style - as a whole. It can be calculated using various parameters collected in real time. Historical data can also be used to calculate the driving mode index. The calculated driving behavior index can be used to make more comprehensive analyzes and estimates of the factors that affect drivers' driving behavior in different driving situations and, for example, in road conditions. The purpose of the Driving Mode Index is to express the driver's current driving style in those circumstances. On the basis of the driving index 5, in some cases it is also possible to make driver selections when searching for the best driver in the system who is able to perform, for example, driving in the dark in a snow on a full trailer truck. As mentioned above, the vehicles already have devices for detecting, for example, a decrease in the driver's vibration state. Such devices make a decision on the reduction of the alert state based on e.g. information from the cameras based on eye movement, as well as deviations from the driver's driving style. However, the decrease in alertness is a factor in the current driving ability that does not take a more general view of the driver's driving style, ie the driver's way of coping - the driving situation in question. Instead, the alert state is one of the factors influencing the driving state, and therefore the determined data about the alert state can also be utilized in determining the driving mode index presented in this solution. The present solution is directed to a system that determines the driver's driving by measuring parameters related to the driver and the driving situation in real time, and by utilizing historical data. The driving style tells you how the driver copes with that driving situation. The driving style index is calculated by combining the driver's well-being data with other data needed to measure the driving style, such as data that reflects the current driving situation. The driver's well-being data can be collected from a personal sensor, N arranged in a well-being device or otherwise worn, whereby the solution also shows the cooperation between the vehicle and the well-being device and the S interface. In this specification, the term 'well-being data' covers all data that can be measured about a person, even if that data does not directly indicate well-being. Thus, there is e.g. driver's heart rate, but also 3 driver's movements. Other examples of well-being data are described in the various examples of the disclosure.
    The object of the invention is to utilize the data produced by existing driving measurement and / or analysis systems together with real-time and / or stored data related to the previous time generated by the driver's personal data and / or the personal well-being sensor. The idea of the invention is thus to supplement the existing driving tracking data with the driver's personal, physiological data (so-called well-being data). In addition, other data obtained from third parties may be utilized in various embodiments of the invention. Figure 1 shows an example of a system and associated data sources. A key element of the invention is the driving style device 100 (i.e., the vehicle tracking system). The driving mode device 100 may be a stand-alone device (a more detailed example is shown in Fig. 4) comprising at least one processor and a memory, and a computer program stored in the memory, and arranged in a vehicle. Alternatively, the functionality of the driving mode device 100 may also be programmatically implemented in a control or other device in the vehicle. - The driving mode device 100 is adapted to collect data from various data sources. Examples include bus data source 108, other vehicles 107, other external data sources 106, driver microphone 103, driver imaging camera 111, such as a video camera, and database 105. The external data source 106 may be, for example, a weather information / weather service. and / or a traffic information service or the like. In addition, the driving device collects personal data from, for example, the driver welfare device 102 and / or the mobile device 109. The database 105 may store historical data, such as location information, speed information, acceleration information, data from vehicle systems that may have been collected by the driving style / tracking system. implementation of the present invention. This database data is supplemented by the driver well-being data (and / or other data related to the driver's physiological characteristics or body functions) collected by the methods according to the invention, as well as by calculated driving behavior indices. S The driving mode device 100 can process the received data to determine the driving mode index>, and transmits the calculation results (cloud or so-called “on-premise”) to the database 105 on the server. 105, which performs data processing and determines the driving mode index.
    N N The data sources shown in Figure 1 are examples of possible data sources. - However, other devices capable of detecting the driver's driving condition, situation, environment, etc. may also be used as a data source.
    Examples of such are a vehicle router, a vehicle computer used for operations control or financing, or an alcohol interlock, for example. In addition to the wellness device, the sources of personal data are telephones and tablets. The driver welfare device 102 may also be a smart watch, a smart ring, an activity wristband, or the like that includes sensors for identifying and measuring parameters related to a person's well-being. The driver welfare device 102 can also be used to identify the driver. Data can be collected from the driver's welfare device 102 e.g. heart rate, heart rate intervals, oxygen saturation, alertness, activity, sleep, body or body temperature, etc. In addition, the driver wellness device 102 may receive and transmit emergency messages from the driver. The driver welfare device 102, together with the mobile device 109, can determine the driver's working time based on the information obtained from the database 105, as well as verify the breaks based on the activity information. The driver welfare device 102 and / or the mobile device 109 may also provide the driver with information about driving style and ability. In addition, the wellness device 102 and / or the mobile device 109 and / or the vehicle information display may receive / transmit information and / or warnings about detected conditions, such as deer, road condition, weather, accidents, etc.
    - In addition to the above, data can be compiled from samples taken from the skin or air, such as a chemical sample that indicates the use of alcohol, drugs, medications. The driver of the vehicle may also have a measuring device consisting of one or more sensors for measuring the movements of the limbs. In this case, the driver's movements become part of the analysis, such as hand movements on the steering wheel, head movements, body movements on the bench. Motion data can be collected by means of the above-mentioned wearable sensors, as well as by means of N motion and pressure sensors on the bench, for example. In motion-based analysis, I- for a woman, it is the observation of how the movements of the driver's hands and body react> to the observations and movements of the car. In addition, data can be collected from an eye tracking system, such as a camera that provides information on eye movements, pupils, N eyebrow positions, etc. Examples of third party data sources include weather and weather services, traffic information services, traffic disruption services, ERP systems, emergency centers. and so on. OF
    The vehicles' own systems also collect a large amount of data on the driving situation, which is intended to be utilized by the vehicle system manufacturer and which can be utilized to achieve the objects of the invention.
    The data may consist of status information from different control devices as well as control, such as
    - for business status, actuator status information, and image recognition.
    Such data can be collected, for example, in an OBD (OnBoard Diagnostic) system. The data sources described above can produce data such as:
    - Location information based on GPS or other location technology;
    - the state of motion of the vehicle in the x-y-z coordinate system, where accelerations and vibrations can also be used to infer road conditions and weather conditions;
    - speed information, eg from a digital tachograph;
    - changes in speed, acceleration, angular acceleration:
    - - wheel speed and its variations;
    - axle balances (car load);
    - power source operating data such as speed, torque, etc .;
    - - status and speed of controls;
    - outdoor data; air and road temperature; humidity; dew point; visibility;
    - road surface scanning, road markings, road sign identification;
    - well-being data, such as heart rate data, stress level, activity level, sleep history, oxygen saturation, body temperature, humidity, alertness, and / or other similar data derived from the well-being sensor;
    - - information related to the driver's driving position, defined eg by the bench and / or steering wheel of the vehicle, the driver's movement information from the telephone, wristband, N watch, clothing, ring, N - - warning signs of the driver's speech; identifiable traits may be S e.g., fatigue, intoxication, aggression, inattention; > - other issues related to the well-being of the driver: prevention of seizures, I 30 anticipation, alarms, eg diabetes, visual impairment, neurological disorders; 3 - the result of the driving test performed on the driver; = - motion and condition information from other components of the car (eg tires), and motion and condition information from trailers; N - information to reduce environmental damage;
    - driving distance, minimum, average and maximum vehicle speed values, maximum vehicle accelerations in different directions and driver identification; - vehicle fuel consumption data, vehicle tire pressure data, vehicle cab / passenger compartment and / or load compartment temperature data, vehicle path information or control and status data for various accessories connected to the vehicle; and so on.
    The driving mode device may utilize more than one of the above information in different combinations to determine the driving mode index.
    The data is received and transmitted over one or more communication networks via a communication interface in the device 100.
    The communication network used is established between the driving mode device 100 and each data source 102, 103, 105, 106, 107, 108, 109, 111.
    Different data transfer methods can be utilized between different pairs of devices, such as Bluetooth, WiFi, and / or 5G and 6G data transfer.
    In some cases, data may be routed from a data source first to a data acquisition device, which forwards the data to the drive device 100. An example of such an arrangement is the transfer of data from a wellness device 102 to a mobile device 109 - its data source.
    In order for the driving mode device 100 to be able to analyze the receiving country data, the data from different sources must be converted to a comparable example using a common data model.
    As a result of harmonization, uniform data packets are generated.
    If the driving mode device 100 does not itself calculate the driving mode index, data packets are provided for processing by the database 105, and for determining the driving mode index.
    The data packets are also stored in the z 30 database 105 for later use.
    Statistics can also be created in the database, compiled from several drivers based on historical data.
    The database 105 can also store basic driver-specific data on, for example, driver shifts, driving style,
    basic diseases, etc. This information can be stored in connection with the driver profile and can be anonymised for use by third parties (eg statistics).
    Based on the data it receives, the driving mode device 100 (or database 105) makes decisions about the driver's driving style by calculating a driving mode index. The driving pressure is stored in a database 105 with driver-specific parameters for the driving situation. In addition, if the driving style index indicates a significant deterioration in the driver 's driving behavior in that situation, the driving style device - 100 will report this 104 and possibly decide to stop driving. The decisions are stored in a database 105 and also transmitted to the driver, for example the wellness device 102 and / or the mobile device 109 and / or the vehicle display. Depending on the driving style, the driving mode device 100 may also control an external system 110, such as vehicle controls, speed limiters, etc.
    The driving mode device 100 is adapted to make an alarm and / or notification also in real time without / before calculating the driving mode index. Such a situation may arise when a sudden change in the data obtained from the driver's well-being sensor is detected, for example in relation to an increase in heart rate or another event indicating a change in health, in which case the driving device is arranged to ask the driver for well-being; to limit driving speed or driving; and / or to report the situation to the driver, for example. A real-time alarm can be issued if the driver suddenly adopts an abnormal driving style that can be attributed to a change in physical or mental health. The alarm can be made to an external party, such as a control room, emergency center, but also inside the vehicle.
    N S The driving mode index is produced in several ways, depending on what, what kind and> how much data is collected about the vehicle and / or its driver. The run print I 30 can be compiled as a data fusion of data from different data sources, dynamically with different weights. Driving mode indices are comparable, but the calculation can be based on statistical processing and generalizations. = Statistics are used when data and / or parameters are used in a limited way. Analyzes can be categorized and named according to the depth of data available.
    The results of the driving mode index calculation can be presented after driving, for example in reports and summaries, reflecting the history. The data source can then also be information collected by other systems in the vehicle. Examples of such a data source are car manufacturers' software and cloud services, which - may include, for example, control and auxiliary device usage information and status information, as well as power source usage information (eg power, torque) and fault information. The model thus enables cooperation with car manufacturers and their software suppliers.
    - In addition to the driving style index, the system can calculate other data focusing on traffic risk management and environmental impact. Examples include the precise targeting of emissions to driving performance, taking into account alternative fuels, and the analysis and presentation of safety risks from performance.
    - The driving style analysis is based not only on welfare-related data but also on third-party data. Data related to changes in the vehicle's operating space are obtained from the vehicle unit acceleration measurement, satellite data and vehicle systems. The analysis is based on the accelerations caused by the forces acting on the vehicle, as well as the acceleration of the vehicle and its changes. These are described in more detail below.
    Vehicle accelerations can be measured by known techniques, such as a micromechanical accelerometer, a gyroscope, a satellite positioning technique that calculates the change in velocity for different axes, and a three-axis acceleration sensor mounted on the vehicle. The accelerations of the vehicle can be measured in the direction of travel in six different directions: forward (acceleration), rearward (braking), left (left-turn), right (right-turn), up (vertical up) and down I 30 - (vertical downward movement). The highest frequency vibration acceleration can be filtered out of the acceleration measurement using both hardware and software filtering. The filtered acceleration data reflects the changes in the operating mode caused by driving the vehicle =. Although the filtering removes some of the effects of external factors affecting the vehicle N, such as the road surface, some of the effects, and in particular the driver's attitude towards them, are still visible in the measurement result.
    The vehicle is set to the acceleration values allowed for its transport. Exceeding the standard limit values will have a negative effect on the driving index, ie the driver will be charged points for exposing the vehicle to excessive acceleration. The standard is based on a large amount of data collected from various traffic over a period of more than ten years. The purpose of using the acceleration standard is to protect the occupants of the vehicle from uncomfortable and vulnerable travel, the damage to the goods being transported, the vehicle itself from wear and tear and damage, and other road users from dangerous driving. The acceleration standard is two-level and is calculated separately for each of the six directions. Mild - error scoring is given for exceeding the first level of the limit values, severe error scoring for exceeding the second level. Repeated crossing of the second level also causes an immediate warning to be displayed to the driver and transmitted to the information system. The set limit values vary slightly according to the type of vehicle and the transport task, as well as the customer's needs and wishes, but as a general rule the limit values are quite limited by the level of travel comfort experienced by people in both passenger and freight transport. In addition to acceleration, the speed of the vehicle and its changes are measured either selectively by the speed calculated by the satellite positioning of the system or directly by the speed indicated by the vehicle bus information.
    N N In the speed analysis, in addition to examining the instantaneous driving speed of the vehicle, a longer-term average speed and minimum and maximum> values are calculated from the speed. In addition, the change in speed is considered in different ways. As in the acceleration analysis, the vehicle is set to the speed limits allowed to drive it. Exceeding the limit values causes a negative score = a score that affects the driving index, ie error points are calculated for the driver = exposure of the vehicle to excessive speeds or speed changes. O OF
    The purpose of using speed limits is to reduce fuel costs and to protect the occupants, goods, the vehicle itself and other transport users from harmful and dangerous speed choices.
    The speed standard is also twofold. The lower continuous driving speed of the so-called the soft limit value is set at a level that meets the needs of the vehicle, the legislation and the operator. The limit value determines the maximum speed that the driver must use when driving continuously. The limit value is compared to the average speed of the vehicle, so the analysis does not significantly take into account the instantaneous speeds exceeding the limit value. The upper instantaneous driving speed of the so-called the hard limit value is also set at a level that meets the needs of the vehicle, the legislation and the operator. The current limit value emphasizes the real safe use of the vehicle, possibly at the expense of legislation. The limit value defines the speed that the driver must not exceed momentarily, e.g.
    - when rolling downhill, accelerating uphill or during overtaking. The limit value is compared to the current speed of the vehicle, so the analysis reacts immediately to speeds exceeding the limit value.
    Exceeding both the lower and upper speed limits will result in a higher error score compared to that limit. If the lower limit value is exceeded, a rather slight error score is given, and if the upper limit value is exceeded, a severe error score is given. Exceeding the upper limit also always causes an immediate warning to be displayed to the driver and transmitted to the information system.
    N The set limits vary according to local regulations, the type of vehicle and the N transport task, as well as the needs and wishes of the customer. The limit values S are typically determined according to vehicle-specific restrictions for heavy vehicles and according to environmental road-specific restrictions for light vehicles. I 30 Monitoring of compliance with road-specific, up-to-date speed limits is in place.
    N = The speed analysis also deals with changes in driving speed in addition to exceeding the above-mentioned N limit values. The changes in speed are analyzed as a small uneven change in driving speed and mainly as a continuous variation in the speed of urban driving. These analyzes use fixed pre-defined limit values that cannot be set on a vehicle- or operator-specific basis. The purpose of the analysis of uneven driving speed is to encourage the driver to drive at a steady speed, preferably using a cruise control, if one is available and suitable for the current driving situation. A steady speed improves traffic safety and smoothness by reducing unnecessary speed variations. The analysis is only active at road speeds. It allows very small speed variations (+2 km / h) without reacting to them. Large speed variations (> £ 5 km / h) are also interpreted as necessary speed changes and are not responded to. Any other speed variation between these is interpreted as harmful and gives a slight error score. The aim of the variable speed analysis is to encourage the driver to drive in a smooth, proactive and predictable manner in agglomeration conditions, provided that it is suitable for the current driving situation. Steady driving speed improves traffic safety and smoothness by reducing unnecessary speed variations. The analysis allows individual speed variations, such as slowing down and accelerating again at a junction, a traffic light or a bus stop, without significantly reacting to them. Only recurrent clear speed changes within a relatively short period of time (round trip> +5 km / h) are interpreted as harmful and give a slightly progressive error score. If a change in speed is found to be related to a change of direction of the vehicle, eg at an intersection, it will not be interpreted as harmful even if repeated.
    N The driver's well-being data is measured using a personal sensor N. In addition to the current well-being S of the driver (heart rate, stress, alertness, etc.), the well-being analysis determines the long-term well-being of the driver (sleep data, increase / decrease of the stress curve, activity, etc.), I 30 - allowing total well-being to be calculated. As in the above-mentioned 3 analyzes, a standard is set for the driver for permissible changes and = deviations from the average well-being. Exceeding the limit values of the standard = causes a scoring that negatively affects the driving behavior index, ie the driver is given error points for too little sleep, too high stress, too low alertness, etc.
    Welfare standards can have two or more levels, and can involve a number of different perspectives on well-being. For example, for heart rate, the lower level limit should be somewhat higher than the resting heart rate, and the upper level should be well above the resting heart rate. Limit values - can be set for driver-specific measured values, or averages. Irrespective of the well-being-related parameter, the higher the undershoot / overshoot compared to that limit value, the higher the error score than the lower value and the higher the upper value.
    In addition to the above-mentioned defined limit values, the well-being analysis also deals with changes in well-being in well-being. Examples of such are heart rate variability or changes in the stress curve, especially while driving.
    Acceleration analysis, velocity analysis, well-being analysis are examples of the analyzes performed. Thus, it is clear that analyzes are also performed on other received data, in which case the examples presented should not be construed as limiting.
    In the above-mentioned, and other possible analyzes of the invention, the decisive factor is not necessarily considered to be exceeding a certain numerical value, but the decisive factor is the deviation from normal in the given condition. Thus, a fixed numerical value or mean is not necessarily essential, but a variance that reflects a normal situation.
    NN Each analysis performed (acceleration analysis, velocity analysis, S well-being analysis in the above examples) yields a score from the above-mentioned measured data that can be summarized into several sub-indices describing driving behavior, such as the acceleration sub-index and the speed sub-index and the speed sub-index. index. The different sub-indices may have their own weighting factor, which may be permanently determined or dynamically determined, the magnitude of each weighting factor varying according to the prevailing conditions. In other words, whenever the time of day is evening and the data from the weather data indicate that road surfaces are frozen, more weight is given to the speed sub-index, but also to the alert state.
    The sub-indices are further condensed (summed / multiplied) into a single driving mode index, ie the driving mode index. The analyzed scoring and the calculated indices are transmitted to the information system for further processing.
    As an example, the system receives data from which an analysis is performed, which is condensed into subscripts A, B, C, D. These can be added together with their own weighting factors to obtain a driving mode index, e.g. A * z + B * y + C * d + D * e = ATI The parameters z, y, d, and e are the above weighting factors, the value of which is determined dynamically from historical data and / or by situation. Based on the driving mode index, the driver's current driving style can be determined. In this case, weight is given to the real-time data obtained from the wellness device, as well as to the previously stored wellness data. For example, if - based on information from the wellness device, the driver of the vehicle is found to have several poorly slept (quantitatively and / or qualitatively) nights behind and a shift from the database would result in a long driving distance, the system may find that the driver's driving condition is reduced, allowing the system to control drivers to take breaks more often or at once - for longer. The driving behavior index or information on the effect of the driving behavior index on the driver's performance can be passed on to work management and / or, for example, occupational health for measures and decisions.
    N In addition, comments can be made on the basis of the driving behavior index, and if the driving style index is not significantly improved, the driver's driving can be restricted by specifying the permitted speed and / or routes, or if the driving behavior index at that time 30 - driving may be interrupted gradually, etc. <= In addition, real-time observations of changes in the driver's state of health may cause restrictions on driving speed, driving range, or driving time. - The driving behavior index (ATI) calculated by the system can be provided to another Fleet Management service provider together with the summaries and analyzes based on it. The driving style index can be used to determine, for example, performance-based user charges, insurance, maintenance services, emergency calls and information related to sharing, leasing and charging. However, it is to be understood that these are examples of potential uses for the Driving Mode Index and, therefore, should not be construed as unnecessarily limiting the invention.
    The numerical value of the driving mode index can be, for example, 0 to 100. For example, the relative driving mode index can be defined so that the best performance of the control group is 100, and others below it on a scale of 0 to 100 or 40 to 100. The relative driving mode index can also be determined , which is 50, the others being between 0 and 50 and 50 to 100.
    The driving mode index can be used to restrict driving, for example by giving a good driver more control and freedom, for example with regard to speed. In addition, unnecessary tips are avoided. Correspondingly, the speed and choice of a driver with a low driving index will be limited and the number of instructions to be given will be increased.
    - The driving mode index can also be used to adjust the vehicle's driving programs. Driving programs can be in various categories, such as "Novice", "Normal", "Sport", the selection of which is controlled by the driving mode index, for example by limiting power and acceleration. .
    N In this case, for example, driver well-being data and data from other data sources are provided as input to the algorithm enabling artificial intelligence, and based on this information, the artificial intelligence solution 101 determines the driver's mode of (sleep quality was good, mind refreshed and active), and / or 3 how a decrease in a physiological parameter affects the current driving condition. = The artificial intelligence solution 101 can also determine the weighting factors of the sub-indices that affect the driving style index.
    N - In order for the AI algorithm 101 to be able to operate in the desired manner and to make decisions about the driver's current driving style, the machine learning algorithm must be practiced with data from which driving situations and the environmental and welfare parameters that affect them can be derived. The machine learning algorithm can be practiced with the data in the database before the algorithm is introduced, but it is also practiced during the use of the driving mode device, on the basis of continuously received data. If an accident or near miss occurs in a driving situation, the training data can be confirmed on the basis of such information, in which case the driving situation that affected the event must be registered. Fig. 2 shows an example of a vehicle 280. The vehicle 280 comprises an electronic unit 270 which receives data from various data sources of the vehicle. The data sources may be a welfare device 202 and one or more vehicle control devices 208. The electronic unit 270 transmits the received data to the database 205 and the calculation unit 200. In addition, the electronic unit 270 may act as a data harmonizer, whereby the transmitted data is already in a comparable form. According to another embodiment, the data may be harmonized in a database 205 or a computing unit 200. The database 205 further receives data from one or more external data sources 250. based on data received from external data sources 250. On the basis of the driving mode index determined by the calculation unit 200, it is possible to control e.g. vehicle 280 controls. The computing unit 200 may be part of a database 205, part of an electronic unit 270, or a stand-alone device. The calculation unit 200 is responsible for the functionality of the driving mode device 100 of FIG.
    N N As one example of a mode of operation and a chain of reasoning, the following is shown: The database stores data from a road network that has marked locations where detours have occurred. In addition, information on the moment of derailment is stored in the I 30 data, such as traffic weather, season, time of day, 3 which are currently collected from the data sources that produce these. In addition, the details of the derailed vehicle and the driver (speed, acceleration, heart rate, alertness, etc.) are also stored. The database also stores N driver profiles, which record at least the driver's age, driving experience and health. Based on the historical data, the system is able to determine the conditions under which derailment has occurred, but also to determine the factors that have contributed to staying on the road under similar conditions. Based on this information, the system makes an assessment of the current driving situation. Data from such a driving situation is received, which includes information about the vehicle, the load of the vehicle, the conditions, the speed and the location of the vehicle. In addition, driver-specific data is received about the driving situation, which includes information about the driver's heart rate, hand moisture and pupil dilation. When the system detects a challenging approach based on location information, as well as the relatively high speed of the vehicle and the accelerating pulse of the driver, this information allows the system to estimate the driving mode index at a low level, not only informing the driver but also informing the driver. as a speed-limiting control command for the vehicle.
    Therefore, based on the analysis of driving situations and the stored data, it is possible to predict the level of risk of driving performance. In this case, the ability of the driver to make decisions and thereby adjust its performance according to the conditions can be described.
    For forecasts, a risk analysis can also be performed on the basis of the different road sections according to a) the accident history and danger points of the road section, b) the geographical profile and road information, c) the condition and driving style of the road, d) the driver's historical data, etc. for each driving situation. In this case, if a certain level of risk is exceeded, it is possible to change the route or driver, for example, and give guidance along the route, for example when approaching risk points.
    N S A method according to one embodiment is shown in Figure 3. The method receives at least 301 data from two or more data sources, at least one of which produces data 3 related to changes in the vehicle's operating mode, and at least one of which produces well-being data measured from the driver; puncturing 302 received data by comparing it to data-specific reference values; generating a corresponding sub-index 303 from each of the scored data; determining a driving mode index 304 based on the generated sub-indices; and controlling 305 vehicle control devices based on the driving mode index and / or storing the driving mode index in a database. The various steps of the method can be implemented with the corresponding hardware and / or software modules of the computer. An apparatus according to one embodiment comprises means for receiving data from two or more data sources, at least one of which produces data related to changes in the state of motion of the vehicle and at least one of which produces well-being data measured from the driver; means for scoring the received data by comparing it to data-specific reference values; means for generating a corresponding subscript from each of the scored data; means for determining the driving mode index on the basis of the generated sub-indices; means for controlling vehicle control devices based on the driving mode index and / or storing the driving mode index in a database.
