Method and device for operating a drive device of a vehicle

摘要

The invention relates to a method for operating a drive device (1) of a vehicle, in particular, a motor vehicle, said device having at least one electric or hydraulic machine (2) as a drive unit. Said method consists of the following steps: determining a target drive direction (ZR) that can be set by the driver of the vehicle, detecting a current direction of travel of the vehicle and comparing the current drive direction with the target drive direction (ZR) that has been set, detecting the direction of action of a current drive force and comparing the direction of action with the target drive direction (ZR), if the current direction of travel deviates from the target drive direction (ZR), detecting/determining unauthorised driving of the vehicle, if the direction of action deviates from the target drive direction (ZR). The invention also relates to a device and a system, in particular, for performing the method.

1. A method for operating a drive device of a vehicle, which includes at least one from the group consisting of an electric machine and a hydraulic machine as a drive unit, the method comprising:
determining a target drive direction which is predefined by a vehicle driver of the vehicle, detecting a current direction of travel of the vehicle and comparing the current direction of travel with the predefined target drive direction, detecting the direction of action of a current drive force and comparing the direction of action with the target drive direction to determine when the current direction of travel deviates from the target drive direction, detecting/determining unauthorized operation of the drive unit of the vehicle when the direction of action of the current drive force deviates from the target drive direction, and during the detection of unauthorized operation of the drive unit, a controller operating to perform at least one of: switch off the drive unit, supply the drive unit with a reduced torque, and activate a brake device of the vehicle.
