Abstract

A method for controlling a vehicle drive unit, which comprises at least two individual drives, at least one of which is able to provide a negative torque. A vehicle control unit is provided, within which a continuous torque comparison is performed within a monitoring level. A permissible torque is ascertained therein. Using a torque range checker it is established whether ascertained setpoint torques lie within torque ranges of the at least two individual drives.
