Problems solved by technology

Even if the time is reduced, this can have negative consequences on the availability of the system, since faults are debounced in less time and lead to disconnection sooner

Embodiment Construction

[0019] figure 1Motor vehicle 101 is shown with one drive train. The motor vehicle has a drive wheel 104 which is mechanically coupled to a drive 102 and a transmission 103 . The driving wheel 104 is provided with a braking device 105 . Controller 108 can communicate with components of the motor vehicle and drive train, in particular exchanging data and sending signals to these components. The controller 108 can thus control the braking device 105 , the transmission 103 , the drive device 102 , and the warning signaling component 106 and receive signals from the operating element 107 and the drive train components 102 to 105 .

[0020] figure 2 A first schematic flow diagram 200 of an exemplary embodiment of a method according to the invention for controlling a drive train is shown. The method starts with step 201 , and in step 202 a setpoint value for the torque of at least one drive device 102 is preset. The actual value of this torque is detected in step 203 . In step...

Abstract

The invention relates to a method and a device for controlling a drive train, in particular for a motor vehicle (101), having at least one drive (102). A set value for the torque of at least one drive device (102) can be preset. Probe the actual value of this torque. And a first signal is generated if the deviation of the actual value from the setpoint is greater than a predeterminable amount of the deviation and / or the deviation of the actual value from the setpoint lasts longer than a predeterminable duration of the deviation amount, the first signal ensures reliable operation of the drive train.

Description

technical field [0001] The invention relates to a method and a device for controlling a drive train. Background technique [0002] Such a method or such a device is known from DE19851457, in which a method and a device for controlling the torque of a drive unit are proposed. A setpoint value for the torque of the drive unit is formed at least on the basis of the position of the operator-operable operating element. Furthermore, the actual value of the torque is detected and at least one control variable for the torque of the drive unit is formed as a function of the setpoint value. Depending on the deviation between the setpoint and actual value, a signal is generated via which the control variable is reduced when the actual value exceeds the setpoint. [0003] The guideline ECE R100 for battery-powered electric vehicles requires that, in the case of a stopped, unbraked motor vehicle, no malfunction (for example in the engine control unit) should result in any movement of m...
