    DESCRIPTION

    Control system for vehicles comprising an on-board diagnostic connection
     5
    SECTOR OF THE TECHNIQUE

    The present invention relates to control systems for vehicles, and more specifically to control systems for vehicles comprising a connection for on-board diagnostics. 10

    PREVIOUS STATE OF THE TECHNIQUE

    Vehicle manufacturers are increasingly sensitized to their safety, which can have an impact on both the occupants of the vehicle itself and the occupants of other vehicles traveling on the same road.

    At present, most of the motor vehicles incorporate a series of properly distributed sensors, which are connected with an on-board diagnostic connection, commonly known by the acronym OBD (from English “On-Board 20 Diagnosis”) or by OBD -II (the second generation), in such a way that by connecting a diagnostic machine to said connector, information regarding said sensors can be obtained, and therefore regarding the safety status of the vehicle in question. Diagnostic machines are found in the mechanical workshops, so the analysis is performed when the vehicle is taken to one of these workshops. In this way, the problems that the vehicle may have automatically and mechanically can be detected, that is, without the need for highly specialized personnel.

    However, with these systems it is necessary to take the vehicle to the corresponding workshop to perform the analysis, and this entails, for example, wasted time for both the workshop 30 and the users of the vehicle. For this reason, there are more and more systems that incorporate a device that connects to the on-board diagnostic connector of the vehicle, and wirelessly transmits the information received to a remote diagnostic machine, which is responsible for doing the analysis, such as for example the system
    disclosed in document ES2228203A1. In this system the information is sent to a remote station, to be read remotely (with respect to the vehicle) by the corresponding diagnostic machine.

    EXHIBITION OF THE INVENTION 5

    The object of the invention is to provide a control system for vehicles comprising a connection for on-board diagnostics, as described below.
     10
    The control system is adapted for vehicles comprising an on-board diagnostic connection, commonly known by the acronym OBD (or OBD-II in its second generation), and comprises a device with a complementary connection to the diagnostic connection of a Vehicle board The device is adapted to wirelessly transmit the data received through the complementary connection to a remote location, so that the state of a vehicle can be analyzed remotely, without the need to take the vehicle to the workshop.

    The device comprises means of access to generate at least one internet access point in the vehicle, so that any user thereof (driver or passenger) can access the internet through said access point. The system also comprises a remote software platform configured to control and manage the generated access point, and to establish communication with the user of the access point.
     25
    In this way, communication can be established between the occupants of the vehicle (internet user in the vehicle through the generated access point) and the software platform via the Internet in a simple way, and this communication can be used to add information both with respect to the vehicle itself, as well as to the security or even to the service offered by said vehicle (relevant in the case of a public service 30 such as a taxi or a bus, for example). For example, a user can report in real time of any anomaly that he detects, such as, for example, any anomaly detected by the driver (brakes, steering, etc.), or any anomaly detected by a passenger (interior lights, reckless driving by the driver, drunkenness
    of the driver, etc.). Thus, the system of the invention allows to add, in real time, relevant information that is not taken into account in any other way, to the information provided through the information received by the device through the on-board diagnostic connection. In addition, thanks to being able to add this additional information, the system may be interesting for other sectors, such as fleet managers, which take into account information beyond the state of the vehicle (or parts of the vehicle) itself.

    These and other advantages and features of the invention will become apparent in view of the figures and the detailed description of the invention.

    DESCRIPTION OF THE DRAWINGS

    Figure 1 shows a schematic view of an embodiment of the system of the invention.

    Figure 2 shows an embodiment of the device of the system of the invention. fifteen

    DETAILED EXHIBITION OF THE INVENTION

    An embodiment of the control system 100 of the invention is shown schematically in Figure 1. System 100 is adapted for vehicles 1 comprising a connection for on-board diagnostics, commonly known by the acronym OBD ("On-Board Diagnosis") or by OBD-II, and comprises a device 2 with a complementary connection 20 to the connection for on-board diagnostic of the vehicle, as shown by way of example in Figure 2. The device 2 is adapted to wirelessly transmit the data received through the complementary connection 20 to a remote location, by generating an internet access point, so that the status of the vehicle 1 can be analyzed remotely, without the need to take the vehicle to the workshop. This access point can operate with a private key, so that it can only be used by people with permission to do so and the information transmitted through it can only be consulted by authorized personnel. 30

    The device 2 comprises access means for generating an internet access point in the vehicle 1, independent of the access point mentioned in the previous paragraph, such that an occupant of said vehicle 1 can access the internet through
    said access point, the device 2 acting as a Wi-Fi router. The system 100 comprises a software platform 3 configured to control and manage the generated access point, and to establish communication with the user of the access point. In this way, a communication is established between the user (vehicle occupant) and the software platform 3 that can provide relevant information to the owner or manager 5 of the system 100, and, in addition, the software platform 3 can know the width consumption bandwidth and can limit the number of users that can access the internet through the access point for example, to maintain the speed and quality of the connection of the connected users. This limitation can be established previously, or it can be established dynamically, depending on the actual bandwidth consumption and if it is deemed appropriate (based on guidelines previously set for example). Software platform 3 could also provide the same bandwidth to each user, so that all users could perceive the same quality of access for example. The system also comprises an operating system that is integrated in device 2 and is designed to control all real-time communications between device 2 and software platform 3.

    In the event that the owner or manager of the system 100 is a fleet manager for example, said owner or manager can obtain real-time information about the users who access the internet in a vehicle 1, and can even receive information 20 sent by such users. This information may be information referring to aspects that the user may have reflected in the vehicle itself 1, aspects related to the driver's habits at that time (drunkenness, reckless driving, etc.), or the quality of the service offered by the vehicle (transport comfort, etc.). In this way, with this additional information, aspects concerning the vehicle 1, 25 related to the safety of the vehicle or with other aspects such as the service offered by it can be controlled, for example, obtaining a more complete control system for vehicles and efficient, and that does not require complex installations for commissioning (it is only necessary to connect device 2 to vehicle 1 through the complementary connection 20, as a pen (“pendrive”). Device 2 is similar in size to 30 a USB memory stick or a USB modem, so that its installation in vehicle 1 is very simple (only the complementary connection 20 needs to be attached to the on-board diagnostic connection of vehicle 1).

    Additional information may also include aspects such as user surveys, the number of users connected to the access point, the bandwidth consumption of the users, the mobile coverage at each point of the trip, and the positioning of the vehicle 1 in every moment (information that can be received on device 2 of a GPS satellite 7 for example). 5

    The software platform 3 is integrated in the cloud 4, thus managing the connections made to the internet in the vehicle 1 through the access point from the cloud 4. This facilitates the processing of the information received from the vehicle 1, regardless of Its location. The integration in the cloud 4 also allows the software platform 10 to comprise an application programming interface (commonly known with the acronym API of the integrated "Application Programming Interface"), which offers a library for use by other software. The operation and characteristics of an API are not commented, since they are already known in the sector. In this case, the software platform 3 is adapted to provide said library with the information it has received, which allows, through other software, this data can be used for the desired applications. In this way, external developers can develop mobile applications that take into account the data available in the library, for example, applications that can be useful for sectors such as insurance companies, workshops, etc., providing greater application and utility to the system 100. 20

    The use of a software platform 3 in the cloud 4 also allows the owner or manager of the system 100 to access it through a PC or through a mobile application for example, through a key system for example.
     25
    To facilitate communication between the user and the software platform 3, said software platform 3 is configured to generate a web when a user connects to the internet in the vehicle 1 through the generated access point, establishing a communication between the user and the software platform 3 through said website. With the website, in addition to controlling who accesses the service (and how many access it for example), legal notices and conditions of use can be provided, for example, information regarding the owner or manager of the system 100, and / or a information to be provided by the user (to continue with the connection for example), by way of a survey for example, with which it can be forced to provide information relating to vehicle 1 or
    service provided by the same as already mentioned, being able to have the manager of this information and at all times. In this way, in addition to being able to perform a general analysis with respect to the vehicle 1 in question (or to vehicles 1 that share the same service or the same fleet), real-time communication allows to identify anomalies in said vehicle 1 in real time, being able to act immediately to solve them if 5 were the case (warning the driver for example).

    The device 2 is also configured to transmit the data received through the complementary connection 20 to the software platform 3, such that the owner or manager of the system 100 can also have the information related to the status of the vehicle 1. Vehicles 1 with a connection for on-board diagnostics comprise a plurality of sensors in accordance with regulations to be applied (for example, the Euro OBD regulations), which provide information regarding technical aspects of the vehicle such as emissions related data. This data is transmitted to the device 2 through the complementary connection 20 and the on-board diagnostic connection of the vehicle 1. In the system 100 of the invention, the holder or manager thereof can thus have both the information provided by these data as the information provided by the user, being able to perform a more complete and effective control of vehicle 1 (and / or the service offered by said vehicle 1), and in real time. Obtaining the information related to the state of the vehicle 1, the information received in the device 2 through the complementary connection 20 and transmitted to the software platform 3, allows for example to be able to detect in real time a bad driving in regard to the environment, thus being able to alert the driver if deemed necessary.

    The device 2 comprises a control unit (not shown in the figures) configured 25 to receive the data received by the device 1 through the complementary connection 20, to encrypt at least part of said data in a certain way, and to send said encrypted data to the software platform 3, the software platform 3 being configured to receive and process said encrypted data. With the encryption, it is possible to encode the information transmitted between the device 2 and the software platform 30, in such a way that it can only be processed if the necessary tools are available to perform the process inverse to the encryption, a quality that the software platform 3 since it is configured to be understood with said device 2 and therefore comprises the software necessary to properly decrypt the
    information received from said device 2.

    In particular, the control unit is configured to compare said received data with data previously stored in said device 2 (in a memory of said device 2, which can be external to the control unit or can be integrated in said 5 unit of control), and to select which part of said data is relevant based on said comparison. The data received by the device 2 through the complementary connection 20 comprises information on the status of a plurality of points of the vehicle 1 (data provided by the sensors as indicated above), and the stored data also includes information on the status of said points 10 of the vehicle 1, specifically information regarding the good condition of said points. In this way, thanks to the comparison, the control unit can determine which points are in good condition and which are not, and can select only those data that do not reflect a good state to encrypt and transmit them to the software platform 3. With this selection you can considerably reduces data traffic and information to be processed 15 by software platform 3, which results in a better overall operation of system 1.

    The control unit is further configured to transmit the encrypted data to the software platform 3 periodically, with a determined time interval between a transmission and the next which can be adjusted according to the needs and / or requirements interposed by the owner or manager of the system 100, and that can be for example 20 seconds. Of course, the smaller the time interval, the greater the data traffic between the device 2 and the software platform 3. Preferably the time interval is configurable, and can be adjusted according to the needs and / or requirements. The adjustment is preferably made by the system manager 100.

    The control unit can also be configured to analyze the encrypted data and to transmit it to the software platform 3 without waiting for any time interval, if with the analysis it determines that the encrypted data includes priority information. Priority is set previously, and can respond to information related to security. Thus, if it is determined that the information present in the encrypted data may advise a vehicle stop for example (based on guidelines previously set and stored in the device, either in an internal memory of the control unit or
    in an external memory to which said control unit has access), said data is immediately transmitted to the software platform 3 to be managed as soon as possible.

    To generate an internet access point in the vehicle 1, a device 2 comprises 5 means of access as discussed above. The access means preferably comprise a SIM card (not shown in the figures) associated with an internet service provider (a mobile telephone operator 5 for example) and a housing (not shown in the figures) to house said SIM card. Internet access is thus provided by an internet service provider, as is the case with a mobile phone 10 for example, ensuring the internet connection to a large extent (will depend on the coverage offered by that provider) and its security (by use of a firewall 6 for example). This type of technology to access the internet is already known, so the system 100 can also provide this service in a simple and safe way. fifteen

    The device 2 can also comprise a memory (not shown in the figures) where the information received by the device 1 is stored through the complementary connection 20, said memory being the same that stores the data relating to the good state of a plurality of points of the vehicle 1 or a different memory 20, and a USB connection (not shown in the figures) through which said stored information can be accessed. In this way the device 2 can be portable outside the vehicle 1, and its information can be accessed even while not being in the vehicle 1. In addition, the USB connection can be used to power the device 2 from another device when used outside the vehicle 1 , as a wireless internet access point for example.

    The system 100 may comprise a plurality of devices 2, a device 2 for each vehicle 1, such as a system associated with a fleet of vehicles 1. In this case the software platform 3 would be configured to control and manage the point 30 of access generated by each of the devices 2, in the manner previously mentioned.
