PURPOSE: A steering hydraulic pressure failure safety typed motor driven steer system is provided to remove a design change about transmission and to provide the steering ability in the malfunctioning. CONSTITUTION: A steering hydraulic pressure failure safety typed motor driven steer system comprises a steering gear(1), a pump(2), an auxiliary cylinder(3), a flow rate indicator(5), a column drive motor(6) and a controller(8). The steering gear comprises a valve inside in order for the fluid pressure according to the steering to be input and output. The pump, driven by the engine, pumps the oil from the reservoir tank and circulates the fluid pressure by the steering gear side. The auxiliary cylinder constitutes the steering gear and the oil-hydraulic circuit in the steering and enlarges the oil force. The flow rate indicator measures whether the mass flow circulating between the pump and the assistant cylinder. The column drive motor is installed to the steering column. The controller decides whether the oil-hydraulic circuit is fixed or not through the flow indicator.
