Abstract

A method for controlling a vehicle drive unit, the vehicle drive unit having at least two individual motors. A total actual torque is continuously compared with an allowable total torque, the total actual torque being calculated from individual actual torque values of the at least two individual motors, and the allowable total torque being calculated from the allowable individual torque values of the at least two individual motors, and an error response being initiated if the comparison establishes that the total actual torque is greater than the allowable total torque.
