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.
Claims10
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 permissible setpoint torques Msetpoint,V and Msetpoint,E are ascertained;
- and
- checking using a torque range checker whether the 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, comprising:
- 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;
- at least one electric drive;
- and
- a torque range checker implemented in the monitoring level, in which a first setpoint torque Msetpoint,V and a second setpoint torque Msetpoint,E are compared to updated torque range limits Mmax,V,Mmin,V,Mmax,E, Mmin,E before calculation of a total setpoint torque.
