    Method and test bench for carrying out a test for a test object
    The present invention relates to a method for carrying out a test on a test bed for a test object, wherein at least one measuring sensor is arranged on the device under test, which detects sensor values of a measured variable, which are supplied to a control unit of the test specimen and in which the detected sensor values of the measured variable in dependence Plausibility be processed to control a function of the DUT. Furthermore, the invention relates to a corresponding test stand and a control unit of a vehicle for carrying out the method.
    In the development of vehicles or vehicle components often powertrain test benches or test stands for complete vehicles are used. In a powertrain, the powertrain is placed on the test rig and connected to one or more load machines (dynamometers). The power train of the drive train, e.g. an internal combustion engine and / or an electric motor, then operates on the test bench against the loading machine to test various load conditions. Such a powertrain test stand is known for example from DE 10 2008 041 883 A1. A test bench for an entire vehicle may be a conventional chassis dynamometer in which the driven vehicle wheels are mounted on test rollers driven by a loading machine. Such a classic chassis dynamometer is e.g. known from DE 100 51 353 A1 or WO 2009/121805 A1. But there are also known test stands, especially for four-wheel vehicles, where the vehicle wheels are removed and attached to the hubs directly, or via special test wheels, loading machines. Such a test stand is known for example from DE 10 2010 017 198 A1 or AT 512 428 B1. On such test benches a real road trip of the vehicle in the form of a test can be simulated very realistic, to test a specific behavior of the vehicle.
    Modern vehicles typically use a combination of controllers that monitor and control various functions of the vehicle. The control units are connected to each other via a vehicle bus, such as a CAN bus, and also exchange data with each other, such as measurement or control variables. In this case, it may also be the case that a first control unit obtains a plausibility check of measured or control variables obtained by a second control unit, possibly also with further obtained measured and / or control variables. If the measurement or control quantities obtained do not appear plausible, a fault condition is assumed which normally only permits limited operation of the vehicle. On a test bench, however, it is often the case that not all required or expected measurement or control variables are available or plausible. An example of this is when not all the axles of the vehicle are driven, as is often the case on a chassis dynamometer. However, many control units monitor measured variables of all vehicle axles with various measuring sensors. If a rotating and a stationary axis is detected, which is not plausible, then this usually leads to a fault condition which normally only allows limited operation of the vehicle.
    On a test bench such a fault condition is normally undesirable because the normal functionality of the vehicle is to be tested on the test bench.
    To prevent this is e.g. It is already known to switch the control units of the vehicle into a special test mode in which certain control units are deactivated or measured variables of certain vehicle-mounted sensors are ignored. DE 10 2007 025 125 B3 describes e.g. a roll mode in which a roll stabilization control device is switched off and the evaluation of a longitudinal acceleration signal, as well as an axle slip function, is deactivated in the transmission control device. Realistic test runs, in which the vehicle dynamics state of the vehicle is to flow in, can not be realized in this way. This can rather a simple inspection of the vehicle, such as in a workshop or at the end of a production (the so-called band end check), be realized.
    In modern vehicles, however, the driving dynamics state, in particular accelerations, such as transverse or longitudinal accelerations or yaw rates, are frequently evaluated and used to control the vehicle or subsystems of the vehicle. By way of example, various driver assistance systems, such as, for example, a vehicle dynamics control system ESP, or the torque distribution as a function of the acceleration state in an all-wheel drive system may be mentioned here. On a test bench but naturally lack such accelerations, since the vehicle, or more generally the DUT, while the test run on the test stand is stationary. Functions of the vehicle that are influenced by the driving dynamics state can therefore not be tested on the test bench without further ado.
    For this purpose, solutions have already been proposed, as described for example in WO 2011/151240 A1. In this case, variables of the vehicle dynamics state are simulated in a model and fed back into the vehicle electronics by emulation of individual signals. The control units of the vehicle thus do not process measured variables detected by a sensor, but calculate and return values calculated in an external simulation. The problem with this is that the real sensors on the test stand have to be removed, or otherwise deactivated, since otherwise contradictory and competing sensor signals are fed to the control units, which in the best case again leads to an error condition due to a lack of plausibility. Apart from this, this procedure is also extremely complicated and therefore disadvantageous.
    It is therefore an object of the present invention to provide a method, and a corresponding test stand, which enables in a simple manner the realistic testing of a vehicle or a subsystem of the vehicle on a test bench, taking into account the vehicle dynamics state. Similarly, it is an object of the invention to provide a control unit of a vehicle which enables the implementation of the method.
    This object is achieved according to the invention by the control unit being switched to a test mode for carrying out the test, calculation values of the same parameter being calculated in a simulation unit, and the calculated values of the control unit being supplied to the control unit in addition to the detected sensor values of the measured variable and the control unit recording the same in test mode Sensor values of the measured variable ignored and the plausibility of the calculated values of the measured variables is omitted. Thus, no intervention in the measuring sensors on the test bench is necessary. The measuring sensors simply deliver their recorded sensor values to the control unit, which however recognizes that the sensor values must not be processed. Instead, the arithmetic values of the same measured variable are processed, which, however, are not made plausible in order to prevent possible fault conditions on the test bench due to implausible values of the measured variable. In this way, a realistic test can be realized on the test bench in a simple manner, which can take into account in particular a vehicle dynamics state of the vehicle. This allows functions to be tested on the test bench that would otherwise not be easily tested.
    The subject invention will be explained in more detail below with reference to Figures 1 to 3, which show by way of example, schematically and not by way of limitation advantageous embodiments of the invention. It shows
    1 shows an example of a test stand with a test specimen for carrying out a test,
    2 and 3 embodiments of a control unit according to the invention and their integration on the test bench
    1 shows a test stand 1 for a test specimen 2, hierein a vehicle, shown in a well-known arrangement. The test piece 2 comprises a drive unit 3, hierz.B. an internal combustion engine which is connected via a clutch 4 to a transmission 5. The transmission 5 is connected to a differential 6, via which in turn two half-axles 7a, 7b of the vehicle 2 are driven. On the driven half-axles 7a, 7b of the vehicle 2 loading machines 8a, 8b are arranged. In the same way, only the drive train could be provided as test specimen 2, for example with an internal combustion engine, clutch 4, transmission 5, differential 6 and half axles 7a, 7b, or in any other configuration, in particular also as a hybrid drive train. Likewise, the driven vehicle wheels could be arranged on test stand rollers of a chassis dynamometer.
    The test object 2 further comprises a vehicle bus 10, for example a CAN, LIN or Flexray bus. In the specimen 2 are also in a well-known manner a variety of
    Measuring sensors Mi, i = 1, ..., x arranged, the respective sensor values SWi, i = 1 ..... x certain
    Measurements MGi, i = 1 ..... x capture. FIG. 1 shows measuring sensors M1, M2, M3, M4, M5 and M6. In addition, a plurality of control units 11, for example an engine control unit ECU, a transmission control unit TCU and a vehicle dynamics control ESP, are provided in the test object 2, which are shown in FIG. 1 only for reasons of clarity outside the test object 2. In the exemplary embodiment shown, the measuring sensors Mi transmit the detected sensor values SWi of the measured quantities MGi via the vehicle bus 10. The vehicle units 10, the control units 11, and possibly also other units of the vehicle 2, can read out the sensor values SWi of the measured quantities MGi and perform a specific, provided function Function, such as the setting of a throttle position or injection quantity of the internal combustion engine, or a gear change, or a braking intervention, etc. process. In the same way, in the exemplary embodiment shown, the control units 11 transmit control variables SGi, i = 1... Y for specific vehicle components via the vehicle bus 10, from which the vehicle components read and process the control variables SGi. However, it could also be provided that certain measuring sensors Mi are connected directly to specific control units 11 and / or specific control units 11 are directly connected to associated vehicle components and not via the vehicle bus 10.
    In FIG. 1, only a few measuring sensors Mi and control units 11 are shown by way of example. Of course, many other and / or other measuring sensors Mi and control units 11 may be provided in a vehicle, which is irrelevant to the following description of the invention.
    In addition, a test stand automation unit 15 is provided on the test bench 1, which controls the test run on the test bench 1. The test bed automation unit 15 controls, in particular, the loading machine (s) 8a, 8b and also the test object 2, in the form of the vehicle or a vehicle component. For this purpose, the test bed automation unit 15 can be connected to the loading machines 8a, 8b. Likewise, the test bed automation unit 15 is connected to the device under test 2 for this purpose, for example via a conventional vehicle diagnostic interface 12, which in turn is connected to the vehicle bus 10. The test bed automation unit 15 could also be connected to other actuators on the test bench 1, such as a driving robot for actuating the pedals, the steering or the transmission. However, the test bed automation unit 15 can also transmit control commands to the respective control units 11 via the vehicle bus 10, such as an accelerator pedal position to the engine control unit ECU.
    In a vehicle, each control unit 11 expects certain metrics MGi. If these measured variables MGi remain off during the operation of the vehicle, then an error state is assumed. It is also customary for the control units 11 to make plausible (in the sense of correctness or trustworthiness) the received sensor values SWi of measured variables MGi in a normal mode of the control unit 11, possibly also with the aid of other sensor values of other measured variables MGi. An example is a plausible combination of the signals of an acceleration sensor, the steering angle and the vehicle yaw rate. A plausibility check can run differently for each measured variable MGi. In general, however, it is known from which other measured variables MGi and / or control variables SGi a particular measured variable is dependent and which sensor values SWi can assume the measured variable MGi, possibly as a function of other measured variables MGi or control variables SGi. The plausibility check is normally implemented fixedly in the control unit 11. If a sensor value SWi can not be made plausible, this usually triggers an error state as well. Such fault conditions are undesirable during the test of the vehicle 2 on the test bench 1, because this makes a realistic test of the vehicle 2, at least for certain functions of the vehicle 2, impossible or difficult.
    In particular, the test stand naturally lacks measured variables MGi of the driving dynamics state of the test object 2, that is to say above all current accelerations, such as longitudinal lateral acceleration, yaw rate, which are recorded with a number of measuring sensors M6 for the driving dynamics. But also measured variables MGi of vehicle control devices, such as e.g. a steering angle, are typically missing at the test bench 1. Similarly, measurands MG1, MG2, e.g. Speeds from measuring sensors M1, M2 are missing from non-driven axles of the vehicle 2. However, such missing sensor values SWi of specific measured variables MGi lead in the combination of the control units 11 to problems or undesired behavior. For example, a driving dynamics control ESP reacts differently when driving straight ahead (steering angle zero) than at a certain steering angle. A speed zero of an axis can signal the vehicle dynamics control ESP a blocking wheel, with a corresponding undesirable reaction of the vehicle dynamics control ESP on the test bench 1. Certain functions of the DUT 2 can not be tested at the test bench 1 without corresponding measures MGi. For example, functions that are dependent on the vehicle dynamics state of the vehicle 2, such as a vehicle dynamics control ESP, a torque distribution in a four-wheel drive or the control of a hybrid powertrain, can not be easily tested on a conventional test bench 1 for these reasons. Here, the invention is intended to remedy the situation, as described below.
    In the exemplary embodiment according to FIG. 2, a control unit 11 receives, via a data input 12, sensor values SWi of a specific measured variable MGi detected by a connected measuring sensor Mi. The data input 12 may be a sensor input 24 to which the measuring sensor Mi can be connected directly. In a plausibility check unit 21, the sensor values SWi are plausibilized and, if plausible, processed in a calculation unit 22 in accordance with an intended function of the control unit 11. The control unit 11 calculates a control quantity SGi which can be output at a data output 13 of the control unit 11. The data output 13 may be a control output 25 of the control unit 11, to which an associated actuator Ai of the vehicle 2 can be connected. The actuator Ai is controlled with the output control quantity SGi. Of course, the plausibility unit 21 and the calculation unit 22 could also be implemented in a single unit and may be implemented in the form of hardware and / or software. 2 corresponds to that of FIG. 2 with the sole difference that the control unit 11 is connected to the vehicle bus 10 via a communication unit 20 and receives the sensor values SWi via the vehicle bus 10 and the communication unit 20 and transmits the control variables SGi , The data input 12 and the data output 13 of the control unit 11 is therefore formed by the communication unit 20 for connecting the control unit 11 to the vehicle bus 10.
    If the measuring sensor Mi does not supply any sensor values SWi of the measured variable MGi which are incorrect or for the test attempt, as determined in the plausibility check unit 21, this could disturb or even make impossible the test attempt to be carried out. It is therefore provided according to the invention that calculated values RWi of the measured variable MGi are determined in a simulation unit 23. The simulation unit 23 can also be implemented in the test bed automation unit 15. This can for example be based on a simulation of the movement of the vehicle, which includes in particular the driving dynamics state of the vehicle, according to the specifications of the test. The simulation can be carried out, for example, using suitable simulation models and can also process other detected sensor values SWi, which are transmitted via the vehicle bus 10, for example. In this way, arithmetic values RWi of measured variables MGi such as accelerations, steering angle, wheel speeds, etc., which would occur during a real drive of the vehicle, which can not be detected at the test bench 1, can be determined on the test bench 1. These calculated values RWi are also supplied to the control unit 11 via the data input 12. Preferably, via the vehicle bus 10, with which the simulation unit 23 is connected, and the communication unit 20. The calculated values RWi could also be supplied to the control unit 11 directly via a provided second sensor input 26 of the control unit 11 as a data input 12, as indicated in Figure 2 , However, this would necessitate a direct connection of the simulation unit 23 to the second sensor input 24. The control unit 11 thus receives sensor values SWi of the measured variable MGi, which are detected simultaneously with the measuring sensor Mi, and calculated calculated values RWi of the same measured variable MGi. Such competing and generally contradictory values of the same measurand MGi would be noticed in the plausibility check in the plausibility check unit 21 and would lead to an undesired error state.
    To prevent this, it is provided that the control unit 11 is switched to a test mode for the test on the test bench 1. This can be done for example by a predetermined, known only to the vehicle manufacturer combination of certain controls of the DUT 2 or by setting a specific encoding value in a diagnostic software. In the same way, this could also be done by a special command, which is transmitted from the test bed automation unit 15 via the vehicle diagnostic interface 12 on the vehicle bus 10 and read by all connected control units 11.
    In the test mode, the control unit 11 is instructed to ignore for the implementation of the intended function of the control unit 11 the sensor values SWi of the measured variable MGi obtained by the measuring sensor Mi and instead to process the calculated values RWi of the measured variable MGi for determining the control variable SGi. For this purpose, provision may be made, for example, for the calculated values RWi to be transmitted by the simulation unit 23 in special messages on the vehicle bus 10 in order to enable the control unit 11 to distinguish the sensor values SWi from the calculated values RWi. In this way it is not necessary for the measuring sensor Mi to be dependent on the vehicle bus 10 or the control unit 11 or otherwise deactivated. There are no interventions on the test piece 2 on the test bench 1 required.
    In order to prevent possible plausibility checks provided in the control unit 11, the control unit 11 in the test mode will at the same time omit the plausibility of the calculated values RWi and will trust the calculated values RWi obtained. "Failure" can mean that a plausibility check is not carried out at all or that the result of the plausibility check is ignored. If the control unit 11 would plausibility check the calculated values RWi of the measured variable MGi with other sensor values SWi of other measured variables MGi (which are transmitted on the vehicle bus 10, for example), then the calculated values RWi might not be able to withstand such a check, which in turn could lead to a fault condition. This can now be prevented by the test mode.
    Although the procedure according to the invention has been described only on the basis of a measured variable MGi, the method can, of course, be applied simultaneously to several and also different measured variables MGi. Likewise, a control unit 11 can also process a plurality of sensor values SWi or calculated values RWi and / or calculate and output a plurality of control variables SGi.
    The software of the control unit 11 is adapted accordingly to allow such a test mode on the test bench 1. This may also be the case in a production version of the control unit 11 which is used in a production vehicle. Optionally, it could also be provided that the control unit 11 or the software of the control unit 11 on the test bench 1 is simply exchanged in order to be able to work on the test stand 1 with a control unit 11 with test mode.
