Abstract

A method for controlling a motor vehicle drive, in particular a hybrid drive, is provided, the motor vehicle drive having at least two individual motors. In a first method step, at least one total setpoint torque is calculated. In a second step, the at least one total setpoint torque is split into at least two individual setpoint torques of the at least two individual motors. Subsequently, in a first individual torque comparison step, the sum of the at least two individual setpoint torques is compared with the total setpoint torque. In the event of a difference by more than a predefined tolerance value, a limitation step is initiated. In this limitation step, the at least two individual setpoint torques are each multiplied by a limiting factor to generate at least two limited individual setpoint torques.
