Method for controlling motor of motor car i.e. sports car, involves controlling rotational torque of motor such that spanning state of drive train of motor car is detected and rotational torque is controlled as function of spanning state

摘要

The method involves controlling rotational torque (1') of a motor such that a spanning state of a drive train of a motor car is detected and the rotational torque is controlled as function of the spanning state to prevent oscillation of the motor car in a longitudinal direction. The spanning state is determined as a rotation speed difference (9) between engine speed and wheel speed that is converted to the engine speed. Reserve rotational torque (13) is constructed and released in a time interval (t-3-t-4) for creation of a rotational torque overshoot (14).
