An electric power steering apparatus for assisting steering of a motor vehicle by conferring torque generated by an electric motor to a steering mechanism, includes a steering controller, which receives signals representative of at least the torque (TTS) applied to a steering wheel and determining a target motor torque (Td), with a microcontroller unit (MCU) and an electronic control unit (WD). A motor controller includes an inverter which transforms from target motor torque (Td) generated target voltages (U1) into motor currents (I1). The WD comprises a memory in which state variables of the MCU are stored and a timer which monitors a blackout time of the MCU, wherein the MCU and WD are linked via a communication bus and a reset line.
