MOTOR DRIVEN TYPE POWER CONTROL STEERING DEVICE

摘要

The 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 voltge applied to an electromagnetic clutch. By modifying a control program for the control unit, it is possible to attain the measures for preventing the burning of a wiring or a battery from occurring 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.
