Motor-driven type power steering control device.

摘要

A motor-driven type power steering control device includes a control unit. When the control unit detects that power elements are short-circuited or in an open state, the control unit cuts off a current supplied from the power elements to a motor and a voltage applied to an electromagnetic clutch. Only by modifying a control program for the control unit, it is possible to attain the measures for preventing that a wiring is burnt or a battery dies upon short-circuiting of the power elements and the measures for preventing that only one side of a steering wheel becomes light to steer upon breakage of the power elements.
