ABSTRACT:
Disclosed is an electric power steering apparatus, in which a gate circuit is provided that allows the actuation of a motor and a clutch only when a signal indicating normal operation is obtained from both of two controllers of dual configuration and that immediately disables steering assisting action when either one or both of the two controllers have gone out of control, and in which a power supply for supplying power to the controllers is connected in common to the two controllers, to prevent a latch-up of either controller.
