Method for safe operation of motor vehicle e.g. electrical car, on track, involves determining actual change in speed of drive assembly, and adjusting target torque in function of actual speed change

摘要

The method involves detecting target torque for a drive unit (20), determining actual change in speed of a drive assembly, and adjusting the target torque in function of the actual speed change. The drive unit is used as an electric machine. Slippage between a wheel (24) of a motor car (10) and a track (26) is determined. The target torque is adjusted with respect to the slippage such that the motor car works against the slippage. A traction control system is used in a traction mode of the drive assembly. An independent claim is also included for a control device for controlling a drive unit of a motor vehicle.
