An electromechanical power steering system for a vehicle may include an electric motor having a stator fitted with at least two electrical winding sets and having a rotor fitted with permanent magnets. The electric motor may exert a steering movement introduced by a driver on the vehicle. A main control unit may determine a motor current prespecification based on the steering movement. The motor current prespecification can be output to the electrical winding sets and may comprise a power control unit that provides and feeds the motor current prespecification to the winding sets. A driver control system may be provided for each winding set, wherein all driver control systems and the main control unit each have a microcontroller and are combined to form an assembly. A power driver may be connected to each of the driver control systems, and at least two power drivers are arranged in a power control unit. Each power driver may be a half-bridge with power semiconductor switches.
