タイム４輪駆動自動車のブレーキ液圧制御装置。A transfer clutch is provided in one of the drive power transmission systems between the front wheels and the rear wheels, and by controlling the transfer clutch to engage and disengage, four-wheel drive and two-wheel drive can be performed. The Aoi brake fluid pressure supply system, which supplies brake fluid pressure to each wheel cylinder of the left and right rear brakes, is equipped with a fluid pressure control valve device that suppresses the maximum brake fluid pressure to a predetermined value. In a four-wheel drive vehicle, when the transfer clutch is engaged and the front and rear wheels are directly connected in a four-wheel drive state, the brake fluid pressure bypasses the above-mentioned fluid pressure control valve device and directly connects the mask cylinder and each wheel cylinder of the left and right rear wheel brakes. A brake fluid pressure control device for a part-time four-wheel drive vehicle, characterized in that a bypass circuit is provided.
