METHOD FOR REGULATING AN ELECTRIC MOTOR OF A DRIVE TRAIN OF A HYBRID VEHICLE

摘要

For a regulation of an electric motor (2) of a drive train (1) for a hybrid vehicle that is simple to implement and carry out, the invention provides that the shaft torque (Tw) of the engine shaft (11) of the current work cycle (n) of the internal combustion engine (3) is detected and fed to a compensation regulator (K), the shaft torque (Tw(n-1)) of a previous work cycle (n-1) of the internal combustion engine (3) is stored in the compensation regulator (K) and a compensated shaft torque (Tkomp) is calculated from the shaft torque (Tw(n)) of the current work cycle (n), the shaft torque (Tw(n-1)) of a previous work cycle (n-1) and the shaft torque of the previous work cycle (n-1) shifted by a system delay. Said compensated shaft torque is linked to the target torque (Tsoll) predefined by a higher-level control unit (15) to determine the controlling torque (Tstell).
