モード切換装置。 The pitman arm of the steering gear box is mechanically connected to each steering arm of the front and rear wheels, and a mode switching means for switching the steering mode is installed in the middle of the linkage on the rear wheel side, while a lock restrains the rear wheels in a neutral position. In a four-wheel steering vehicle in which each actuator of the mode switching means and the locking means is controlled according to a mode switching request by a control unit composed of a microcomputer, a battery relay is interposed in the power supply circuit of each actuator. A mode switching device for a four-wheel steered vehicle, further comprising a drive circuit that outputs a drive signal to the battery relay only when a predetermined operating condition is satisfied based on a plurality of signals from a control unit.
