    Method and test stand for testing a starter motor
    The invention relates to a method and a test stand for testing a starter motor with an electric load machine connected to the starter motor, which simulates an internal combustion engine, and a controller for controlling the electric loading machine.
    Starter motors for internal combustion engines are subject to new technologies, e.g. the start-stop technology, ever higher demands, especially as regards the required number of starts. Whereas 5,000 years ago, 30,000 take-offs were required, today, starter motors are already demanding 300,000 take-offs. This also necessarily increases the requirements for testing starter motors. So far, conventional tests on the real internal combustion engine are therefore hardly perform. On the one hand, because at the time of testing a starter motor for a new internal combustion engine or for a new drive train, this is often not even available and on the other hand, because the cost of such a test stand due to the necessary media connections and supply lines, e.g. for cooling water, fuel, exhaust gas, oil, etc., the internal combustion engine for cost and time reasons is too high.
    For this reason, test benches have been designed for starter motors of internal combustion engines, in which the internal combustion engine is replaced by an electric machine and simulated. DE 10 2006 045 973 A1 describes such a test stand. Therein, the electric machine is regulated according to a predefinable test characteristic. The test characteristic can be created from measurements on the real internal combustion engine or from a virtual engine model. The test characteristic is then specified for the respective test run and is at each test run, the e.g. Repeated 50,000 times.
    The problem is that a system of starter motor and internal combustion engine does not have an exact deterministic temporal behavior. Rather, such an electro-mechanical system indicates, within certain limits, temporally random behavior that can change in the order of milliseconds. For example, The timing varies from the time of the start signal to the start of the starter pinion and until the starter motor builds up the required torque due to the mechanics and electromechanical parts (e.g., relays). Likewise, there may be temporal variations in torque generation. As a result, the theoretical test characteristic and the real operation do not coincide completely, but there may be a time offset. If the starter motor e.g. according to the test curve should already be started, so should already have a speed n ^ 0, there may be occurrences that the load machine still a speed n = 0 is given, which acts as a blocking motor. As a result, the starter current would be greatly increased.

    .............. AV-3456 AT, which can lead to unrealistic loads on the starter motor or on the starter pinion and starter ring. Such a test run would not be representative and could not be considered in the test. In addition, practical experiments have also shown that result in operation with such a test rig damage images on the starter motor, which do not occur in practice. However, such a test bench is useless for real tests of starter motors.
    It is therefore an object of the subject invention to overcome the above-mentioned problems in testing starter motors on test stands with an electric loading machine.
    This object is achieved according to the invention by determining in a simulation unit, in which a mathematical model of the internal combustion engine is implemented, with the mathematical model from measured actual variables of the operation of the electrical loading machine at each sampling instant of the control, a new desired load value, which is supplied to the controller , The fact that no time-based test characteristic is specified, but at each sampling time of the control of the expected current state of the engine is calculated, it is guaranteed at any time that the control is based on the current state, whereby a temporal offset of actual state and target specifications is avoided , Thus, such a scheme is insensitive to unavoidable, random temporal variations in the electromechanical system of internal combustion engine and starter motor.
    The accuracy of the test stand or of the test method can be increased if the moment of inertia of the electrical loading machine essentially corresponds to the moment of inertia of the actual internal combustion engine.
    The subject invention will be explained in more detail below with reference to the exemplary, schematic and non-limiting Figures 1 and 2. It shows
    Fig. 1 shows a test stand according to the invention and
    Fig. 2 is a block diagram of the control concept according to the invention.
    A test rig 1 according to the invention for testing starter motors 2, as shown in FIG. 1, comprises an electrical loading machine 3, e.g. a permanent-magnetically excited synchronous machine, a holding device 5, for the correct fixing of a starter motor 2, and a base frame 4, on which the individual part of the test stand 1 are arranged. Furthermore, an electrical supply unit 11, e.g. a 12V vehicle battery or a battery simulator provided (see Fig.2). If a battery simulator is used, test runs with different battery charge states can also be carried out. -2- Φ Φ Φ * Φ φ Φ ·· ΦΦ ΦΦ Φ «« · * Φ Φ *** '···· * ·· ί. · · »· * AV-3456 ΑΤ
    The holding device 5 can provide a receiving device 6, to which the starter motor 2 is fastened. The receiving device 6 can be moved relative to the holding device 5 and / or the holding device 5 can be moved relative to the basic position 4 in order to simply move the starter motor 2 in the correct position Likewise, it is possible to arrange a second starter motor 2 on the test stand 1, as shown in Figure 1 in order to be able to test several starter motors 2 simultaneously with one test stand. For this purpose, it can be provided that a further starter motor 2 is likewise arranged on the holding device 5. Alternatively, this can be arranged with a receiving device 6 directly on the base frame 4.
    On the output side, a starter ring 7 is provided on the electric loading machine 3. The starter ring 7 corresponds preferably to the real starter ring, as it would be installed in a vehicle. On the starter motor 2, a known starter pinion 8 (see Figure 2), not shown here, arranged that einspurt for the starting process in the starter ring 7. The meshing and starting process is known per se, which is why it will not be discussed further here. The electric loading machine 3 simulates an internal combustion engine that is to be started by the starter motor 2. It can also be provided to bring the starter ring 7 before the start of a test run a parameterizable position.
    At the electric loading machine 3, as shown in Fig. 2, measuring means are arranged, e.g. an angle sensor 10 for detecting the rotational angle < p, and / or rotational speed ni, and / or a measuring flange 9 for detecting torque Ti of the electrical loading machine 3. Of course, the rotational speed ni can also be derived from the rotational angle (pi.
    In a simulation unit 20, a mathematical model of the internal combustion engine is simulated, which simulates the internal combustion engine. In this case, the model is preferably designed so that this can simulate the engine from the start, so starting from speed n = 0, simulate. Simulating in this context means that the model is a current operating state of the internal combustion engine based on a current Istdrehwinkel φ ,, or equivalent elapsed time, from start and based on a current operating state of the electric load machine 3, e.g. in the form of an actual speed n, and / or an actual torque Tit can calculate and output in the form of a load setpoint, e.g. a Soildrehzahl ns in the case of a speed control or a desired torque Ts in the case of a torque control. The load setpoint calculated in this way is fed to a controller 21, which calculates a torque setting value Tsten or rotational speed setting value ηε (βιι) and thus regulates the electrical loading machine 3.
    AV-3456 AT 21 can also display the current actual values, e.g. Actual rotation angle φ ,, actual speed n, and / or actual torque T, is obtained.
    The test run is controlled, monitored and evaluated by a test bed control unit 22. The test bench control unit 22 can be connected to the simulation unit 20, to the controller 21, to the starter motor 21 and / or to the electrical loading machine 3 and to exchange data. In particular, a test run is started by the test bench control unit 22 by a start signal.
    After the start of the test run, the simulation unit 20 calculates from the mathematical model at each sampling time of the control, e.g. every 100psec. for the current rotation angle < p from start or for the current time from start, the correct current operating state of the internal combustion engine and passes a load setpoint, e.g. in the form of a setpoint speed ns and / or a setpoint torque TBl to the controller 21, which sets this setpoint input, e.g. is converted into a real torque (torque setting value Tsten) of the electric loading machine 3, i. the electric loading machine 3 controls so that the calculated load condition for the starter motor 2 adjusts to the electric loading machine 3.
    Due to the high dynamics of the behavior of the internal combustion engine, or the electrical loading machine 3 as a simulation of the internal combustion engine, it is advantageous if the control used in the controller 21 has a short dead time, preferably < 1msec, which allows a fast response to changes in the actual values and a high sampling frequency of the control, e.g. as here 10kHz, allows. It is also possible to use self-learning control algorithms known per se with which the dead time in the control loop is at least partially compensated.
    Likewise, it is advantageous if the moment of inertia of the electrical loading machine 3 substantially corresponds to the moment of inertia of the actual internal combustion engine. The moments of inertia preferably differ by a maximum of 20%, more preferably by a maximum of 10% and most preferably by a maximum of 5%. The moment of inertia of the internal combustion engine is simulated by the electrical loading machine 3. This inertial simulation does not work ideally for system dead times and system non-linearities. However, the closer the inertia to be simulated is to the real inertia of the electric machine, the more accurate the simulation of the internal combustion engine or the test bench 1 for testing the starter motor 2. -4-
