Patent ID: 7400962

Claim:
A method for regulating drive torque following a load change in a hybrid vehicle, comprising: influencing the drive torque at driven wheels following the load change so that a brake slip at the driven wheels of the hybrid vehicle resulting from the load change is counteracted in a beginning phase in such a way that an effect on lateral stability and on stability of the hybrid vehicle during driving, is excluded; when brake slip occurs at the driven wheels because of the load change, applying the drive torque via at least one electromotor of the hybrid vehicle; upon detection of the brake slip following a load change, calculating a setpoint drive torque and inputting the calculated setpoint drive torque for a drive control in which a drive torque for an internal combustion engine of the hybrid vehicle and drive torque for the electromotor are determined by an algorithm for an operating strategy, and which sets a setpoint torque of the electromotor to be equivalent to the calculated setpoint drive torque if the calculated setpoint drive torque is less or equal to a maximally possible drive torque of the electromotor in an instantaneous operating point; and if a condition according to which the calculated setpoint drive torque is less or equal to the maximally possible drive torque of the electromotor in the instantaneous operating point, is not satisfied, applying by the internal combustion engine, a portion of the drive torque that exceeds the maximally possible drive torque of the electromotor; wherein the setpoint torque of the electromotor is set to be equivalent to the calculated setpoint drive torque if a query of a charge state of a battery has shown that the battery is sufficiently charged.
