A motor driving method for a steering apparatus for applying an auxiliary steering force to a steering system with two motors. When the two motors are driven, a first one of the two motors is operated first. Thereafter, the other, second motor is driven, whereby smooth steering is effected.

Steering system for vehicle

Steering apparatus for transmitting a driving force of a motor through a gear mechanism to a rack shaft of a steering system and applying the driving force to steering road wheels in a steering direction. The apparatus has first and second motors. In the transmission of driving forces from output shafts of the first and second motors to the rack shaft, the phases of the two motors are essentially staggered by 180 degree.

An electric power steering apparatus with a plurality of motors for applying a force to steering road wheels in a steering direction with mechanism which applies an increase in allocation of auxiliary steering force to an operating motor when at least one of the motors has failed.
