Abstract: The invention relates to an electronically commutated electric motor. The electric motor comprises a stator, and a rotor, in particular a permanent-magnetic rotor. The electric motor further comprises a control unit connected to the stator. The control unit is designed to actuate the stator such that the stator can generate a magnetic rotating field for rotationally moving the rotor. According to the invention, the control unit of the electric motor is provided with a power output stage having semiconductor switches. Subject to the low-resistance, or short-circuited, semiconductor switch of the power output stage, in particular as a result of defect, the control unit is designed to actuate the stator for generating the rotating field such that during a complete rotor revolution, the rotor can provide a mechanical output, or in the operational mode, a braking torque of the electric motor caused by the defect is reduced, or completely neutralized, by the low-resistance, or short-circuited, semiconductor switch.

Abstract: The invention relates to a control device for regulating or controlling a servo-drive unit in a steering system of a vehicle. In order to determine the initial zero position of the steering shaft the value of at least one vehicle state variable is taken into consideration as an input signal, said variable not being a steering angle variable. The steering shaft is in the initial zero position if said vehicle state variable within a defined range of values.

Abstract: The invention relates to a steering device for a vehicle, comprising a steering drive (1) having an output shaft (2) for assisting a steering process, and a blocking device (3) for blocking the steering drive (1). Said blocking device (3) is directly arranged on the steering drive (1) and blocks the steering drive directly on the output shaft (2). The invention also relates to a method for blocking a steering device.

Abstract: The invention relates to a steering device for a motor vehicle. Said steering device comprises a drive (10), especially an electromotive drive. Said drive is designed to generate torque for assisting the steering of a motor vehicle. According to the invention, the steering device comprises an electromagnetic steering lock (5,7,11,16) comprising a blocking element (11) that can be moved back and forth along a translation axis (25) or about a pivoting axis (23). The blocking element is arranged and designed in such a way as to engage in the drive (22) in a form-fitting and/or force-fitting manner, in order to block the steering. The steering lock comprises at least two, or exactly two, electromagnetic coils (5, 7) that are actively connected to the blocking element, the electromagnetic coils being respectively arranged and designed in such a way as to move the blocking element back and forth when current flows through them.
