A method for driving a multiphase motor by a drive circuit, wherein the drive circuit comprises a plurality of transistors, and for each phase of the motor are provided a first path and a second path, wherein at least one transistor is assigned to the first path and to the second path of each of the different phases, and wherein a normal mode, a first drive mode, and a third drive mode are provided, wherein for the first drive mode, all the transistors in the second paths are short-circuited, and for the third drive mode, all the transistors are opened. The method includes detecting an undervoltage or an overvoltage in the drive circuit, operating the drive circuit in the first drive mode if a first undervoltage has been detected, and operating the drive circuit in the second drive mode if a second undervoltage has been detected.

Method for driving, drive circuit, brake system and use

A method for hydraulically boosting a vehicle electric parking brake having a hydraulic service brake and an electric parking brake. Application forces electically generated by the parking brake function is superimposed on the boosting brake force generated by a hydraulic boosting brake pressure provided by the service brake to the brake actuator. When the parking brake is actuated to generate a predetermined application force, the force generated by the brake actuator is detected as the actual value, if an actual value of the measured value is smaller than a first target value a boosting brake pressure value is applied to the brake actuator, and by means of the parking brake function an adjustment function for the tension of the brake actuator to which the hydraulic boosting brake pressure is applied is carried out to achieve the predetermined application force.
