Abstract

A method and a device for controlling a drive unit of a vehicle in which the actual torque of the drive unit is compared to a specified, maximum allowable torque for monitoring purposes. When the actual torque exceeds the maximum allowable torque, the drive unit is controlled in a torque-reducing manner. The actual torque of the drive unit is determined on the basis of a signal representing vehicle acceleration. Instead of comparing absolute values, a differential comparison is carried out.
