Abstract
An electric motor () of a drive train () of a hybrid vehicle is controlled by determining the shaft torque (T) of a current work cycle (n) of an included internal combustion engine () and feeding the shaft torque (T) to a compensation controller (K) which has stored the shaft torque (T(n−1)) of a preceding work cycle (n−1) of the internal combustion engine, and calculating a compensated shaft torque (T) from the shaft torque (T(n)) of the current work cycle (n), the shaft torque (T(n−1)) of a previous work cycle (n−1), and the shaft torque of a previous work cycle (n−1) shifted by a system delay, which compensated shaft torque (T) is linked to a target torque (T) predefined by a higher-level control unit () to determine the controlling torque (T) for the electric motor.
