Claim 0:
1. A method for controlling a driving dynamics control device which is configured to influence braking of wheels of a motor vehicle, the driving dynamics control device including a pump which includes at least two pump elements configured to supply brake fluid, and an electric motor which includes a rotor and a stator configured to drive the pump elements, the method comprising the following steps:
determining an ideal position for the rotor relative to the stator, the ideal position being determined by:
generating a predefined counterpressure against the supply by the pump of the brake fluid, and
detecting the current of the electric motor required to drive the pump elements to supply the brake fluid against the generated counterpressure, the position of the rotor relative to the stator in which the detected required current for the electric motor to drive the pump elements to supply the brake fluid against the generated counterpressure lies below a predefined current value being defined as the ideal position;

detecting a position of the rotor relative to the stator; and
adjusting the position of the rotor relative to the stator to the ideal position, a sum of torques for moving the pump elements lying below a predefined torque limit value in the ideal position.
