| description | This application provides a hydraulic adjustment apparatus, a hydraulic adjustment unit, a brake system, and a control method, to reduce a quantity of control valves matched with the hydraulic adjustment apparatus in the hydraulic adjustment unit and reduce costs of the hydraulic adjustment unit. This application is applicable to intelligent automobiles, new energy automobiles, conventional automobiles, or the like. In embodiments of this application, a fluid outlet pipe of a first hydraulic chamber 16 is configured in segments on a push rod support portion 14 and a push rod 13. In this way, when a piston 12 is located at an inner stop point of a piston stroke, a first hydraulic adjustment port 14a located on the push rod support portion 14 communicates with a second hydraulic adjustment port 13a located on the push rod 13, and when the piston 12 is located at a position other than the inner stop point in the piston stroke, the first hydraulic adjustment port 14a does not communicate with the second hydraulic adjustment port 13a. This avoids a need in a conventional hydraulic adjustment apparatus to specially configure a control valve for a first hydraulic chamber 16 to control a fluid outlet pipe corresponding to the first hydraulic chamber 16 to be open or closed. |
