Abstract

The invention discloses an automobile hydraulic brake system, which comprises a vacuum booster, a main brake cylinder and an ABS pump; a front cavity of the vacuum booster is connected with a vacuum source, and a pressure sensor is arranged on a pipeline between the ABS pump and the main brake cylinder; the pressure sensor is connected with a controller; a vacuum valve opening of the valve core of the vacuum booster is connected with a hose, and the hose is connected with the vacuum source through a normally-open electromagnetic valve after crossing through the outer wall of the front cavity of the vacuum booster; a normally-closed electromagnetic valve connected with air is arranged on the pipeline between the normally-open electromagnetic valve and the hose; the normally-open electromagnetic valve and the normally-open electromagnetic valve are connected with the controller. Through the pressure sensor, the brake system pressure feeds back in real time; the controller controls the pushing or retreating amount of a push rod of the vacuum booster according to pressure of the brake system, thus the electronic control of the automobile brake fluid system is realized on the basis of original manual control; the safety and reliability are improved.

Description

technical field [0001] The invention belongs to the technical field of automobile braking, in particular to an automobile hydraulic braking system. Background technique [0002] With the continuous development of smart car technology, various anti-collision products of cars and related technologies of automatic driving and unmanned driving are developing rapidly. Therefore, there is an urgent need for a reliable and electronically controlled car braking system to Meet the actual needs of smart car development. The hydraulic braking system is currently a relatively stable automotive braking system. However, it is either applied to manual mechanical control or purely electric control. For example, when applied to manual mechanical control, the automotive braking system mainly includes vacuum booster booster, brake master cylinder, anti-lock brake system and brake wheel cylinder, and the front cavity of the vacuum booster is connected with a vacuum source. When the vacuum boo...
