Claim 15:
16. A driving dynamics control device for influencing braking of wheels of a motor vehicle, the driving dynamics control device comprising:
a pump having at least two pump elements for a supply of a brake fluid;
an electric motor including a rotor and a stator configured to drive the pump elements;
a position detection device configured to detect a position of the rotor relative to the stator; and
a control device configured to adjust the position of the rotor relative to the stator to an ideal position, a sum of torques for moving the pump elements lying below a predefined torque limit value in the ideal position;
wherein the ideal position for the rotor relative to the stator is 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.
