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.

A method for controlling a vehicle drive unit which includes at least two individual drives, at least one of which may provide a negative torque, and a vehicle control unit, the method comprising:
- performing a continuous torque comparison within a monitoring level, in which a permissible torque is ascertained;
- and
- checking using a torque range checker whether ascertained setpoint torques Msetpoint,V, and Msetpoint,E lie within torque ranges of the at least two individual drives.
A vehicle control unit for a combination drive, including at least one internal combustion engine and at least one electric drive, the vehicle control unit having a functional level and a monitoring level for the at least one internal combustion engine, and at least one electric drive, and a torque range checker implemented in the monitoring level, in which setpoint torques Msetpoint,V and Msetpoint,E are compared to respective updated torque range limits Mmax,V, Mmin,V, Mmax,E and Mmin,E before calculation of a total setpoint torque.
