Abstract

The invention belongs to the technical field of automobiles, and discloses a hydraulic braking system and a hydraulic braking control method. The hydraulic braking system comprises a liquid storage reservoir, a brake wheel cylinder mechanism, a liquid outlet control mechanism, a hydraulic braking cylinder, a brake pedal, a booster cylinder and a liquid inlet control mechanism, wherein the liquid storage reservoir is used for storing a brake fluid; the brake wheel cylinder mechanism selectively communicates with the liquid storage reservoir through the liquid outlet control mechanism; the hydraulic braking cylinder communicates with the liquid storage reservoir, and a brake piston is arranged in the hydraulic braking cylinder in a sliding mode; the brake pedal is connected to the brake piston through a push rod; the booster cylinder communicates with the liquid storage reservoir, and a booster piston is arranged in the booster cylinder in the sliding mode; and one end of the liquid inlet control mechanism selectively communicates with the hydraulic braking cylinder and the booster cylinder, and the other end of the liquid inlet control mechanism selectively communicates with the brake wheel cylinder mechanism. According to the hydraulic braking system, the boost braking function of an electric boost braking system can be realized, and the function of a vehicle body stabilizing system can also be realized, so that the boost braking function and the vehicle body stabilizing control function are integrated, and the user experience is increased.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a hydraulic braking system and a hydraulic braking control method. Background technique [0002] With the current development of vehicles in the direction of electrification and intelligence, on the one hand, the demand for new energy vehicles is increasing, and on the other hand, the proposal of intelligent driving has also greatly promoted the development of vehicle intelligent control. [0003] In terms of braking, most new energy vehicles currently use vacuum boosters and rely on the vacuum source of the vacuum pump to provide assistance. Due to the current problem of the life of the vacuum pump, new energy vehicles have been recalled due to the vacuum pump. Another part of new energy vehicles began to use electronically controlled power-assisted braking system, which meets the requirements of vehicle regulations in terms of durability, and its functionality far exceeds t...
