Abstract: A braking system includes a main braking subsystem and a redundant braking subsystem, where the main braking subsystem includes a brake master cylinder, and the redundant braking subsystem includes a redundant boosting apparatus and a third isolation valve. The redundant boosting apparatus includes a first input end and a first output end. The first input end is configured to input a brake fluid, and the first output end of the redundant boosting apparatus is hydraulically connected to the brake master cylinder.

Abstract: This application provides a brake-by-wire system and a control method. This application is applicable to an intelligent vehicle, a new energy vehicle, a conventional vehicle, or the like. The braking control system includes: a brake master cylinder, a first pressure booster, a second pressure booster, at least one second control valve, at least one third control valve, at least one fourth control valve, and a second pedal feel simulation system. When a master brake system fails, a redundant brake system can independently control each brake wheel cylinder, to implement function backup for a master brake system, meeting requirements for braking functions such as ABS/AEB/ESC/TCS of a vehicle. The redundant brake system can further improve safety of the brake system and ensure pedal experience of a driver, thereby bringing more stable and comfortable driving experience to the driver.

Abstract: A hydraulic control unit is provided, including a hydraulic control apparatus with a bidirectional pressurization function, where the hydraulic control apparatus includes a second hydraulic chamber and a first hydraulic chamber. The second hydraulic chamber provides a braking force for a first group of wheel cylinders through a first brake line provided with a first control valve. The first hydraulic chamber provides a braking force for a second group of wheel cylinders through a second brake line provided with a second control valve.

Abstract: 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.

Abstract: This application provides a hydraulic adjustment unit, a brake system, an automobile, and a control method, to individually pressurize any brake pipe in a dual circuit brake pipe, to improve safety of a dual circuit brake system. This application is applicable to an intelligent car, a new energy car, a conventional car, or the like. In embodiments of this application, a second hydraulic chamber provides a braking force for a first group of brake wheel cylinders and through a first brake pipe provided with a first control valve, and provides a braking force for a second group of brake wheel cylinders and through a second brake pipe provided with a second control valve.

Abstract: In a method for moving a vehicle out of a parking area, the vehicle obtains map information of the parking area and determines a current parking space of the vehicle and an exit location of the parking area. The vehicle determines a plurality of target departure routes from the current parking space to the exit location, and identifies blocking vehicles on the target departure routes that blocks it from reaching the exit. The vehicle estimates the preferability of each of the target departure routes based on a number of blocking vehicles on the target departure route and a difficulty level of removing the blocking vehicles from the target departure route. The vehicle then selects from the target departure routes a preferred departure route, and transmits requests to remove the blocking vehicles off the preferred departure route.

Abstract: A hydraulic adjustment unit of a brake system in a vehicle includes a first fluid reservoir (29), a second fluid reservoir (2), a first oil return pipe (110), and a second oil return pipe (120). The first oil return pipe (110) is connected to wheel cylinders (151, 152) of a vehicle, so that brake fluid in the wheel cylinders (151, 152) of the vehicle is delivered to the first fluid reservoir (29), to depressurize wheels of the vehicle. The second oil return pipe (120) is configured to connect to the wheel cylinders (151, 152) of the vehicle through oil inlet pipes (130, 140) of a brake system, so that the brake fluid in the wheel cylinders (151, 152) of the vehicle is delivered to the second fluid reservoir (2) through the oil inlet pipes (130, 140) of the brake system, to depressurize the wheels of the vehicle.
