Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To continue generation of a steering assist force by securing a proper control power without being affected by variation of a battery voltage. SOLUTION: This electric power steering controlling device comprises steering torque detection means 17 detecting a steering torque, an electric motor 5 generating a steering assist force to a steering system, and steering assist controlling means 3 controlling the electric motor based on the steering torque detected by the steering torque detection means 17. The device is provided with a control power formation circuit 20 forming a controlling power by increasing a battery voltage of a vehicle-mounted battery 1, and supplying the formed controlling power to at least the steering assist controlling means 3.
