特徴とするディファレンシャルロック装置付４輪駆動車
のパワーステアリング制御装置。This is a four-wheel drive vehicle in which the front and rear wheels are driven, and a center differential is provided at the point where the drive transmission to the front and rear wheels diverges, and a rear differential device is provided on the rear axle. Both differential devices are each equipped with a differential lock means, and both differential lock means are actuated by a hydraulic actuator whose operation is controlled by a switching valve, and the switching valve is in the switching position of the differential lock switching device. The switching positions of this differential lock switching device include a first switching position where both of the differential lock means are controlled to be inactive, and a first switching position where only the differential lock means of the center differential device is controlled. There are three switching positions: a second switching position that controls the differential locking means to be activated, and a third switching position that controls both of the differential locking means to be activated. A four-wheel differential lock device is equipped with a hydraulic power steering device, and a bypass valve is provided in the hydraulic oil path that supplies the hydraulic pressure to the working hydraulic chamber of the hydraulic power steering device, so that the supplied hydraulic pressure is bypass-controlled. In the power steering control device for a driven vehicle, the bypass valve of the hydraulic power steering device is configured to variably control the bypass amount of the supplied hydraulic pressure, and its control state changes depending on the switching position of the differential lock switching device. The amount of bypass is controlled to decrease in the order of the first switching position, the second switching position, and the third switching position, and from this the assist force of the hydraulic power steering device is sequentially increased. be made stronger. A power steering control device for 4-wheel drive vehicles with a differential lock device featuring Kokichi.
