The invention relates to a device for collecting hydraulic pressure and liquid demand data of an automobile brake system, and belongs to a data collecting device of the automobile brake system. The front end of the body is fixedly connected with an oil pipe connector, a normally-closed linear electromagnetic valve, a hydraulic sensor and a normally-closed electromagnetic valve are fixedly connected to the body, an exhaust screw is in threaded connection with the bottom of the normally-closed electromagnetic valve, a piston is in sliding connection with the interior of the body, the top of the piston is aligned with an oil outlet of the normally-closed linear electromagnetic valve, a limiting nut is fixedly connected into the body, a motor drives the rear end of a rack push rod, the middle of the rack push rod penetrates through the limiting nut, the front end of the rack push rod abuts against the rear end of the piston, and a displacement measuring device is fixed on the body. The device has the advantages that: the structure is novel, the displacement measuring device and the hydraulic sensor are used for accurately measuring hydraulic force and required liquid volume, the hydraulic sensor detects that the pressure is stable, a normally-open valve is closed, and the displacement measuring device measures moving displacement, so that accurate data can be provided for automobile brake control, and the brake performance and the brake comfort are improved.
