AI Technical Summary

Problems solved by technology

However, the existing scheme can only use conventional hydraulic brakes for the front wheels and EMB for the rear wheels.
In this solution, when the vehicle is in normal working condition, the system is still complicated and costly because the front wheels retain hydraulic brakes, and the advantages of EMB are not fully utilized.

Abstract

A braking system comprises a pedal assembly (1), a hydraulic assembly (2), a reversing assembly (3), a driving wheel assembly, a pedal feeling simulator (6) and a first electronic control unit (7), the first electronic control unit (7) is electrically connected with the reversing assembly (3) and can control the reversing assembly (3) to switch working positions, and the reversing assembly (3) comprises at least two working positions. At the first working position, a brake fluid output port of the hydraulic assembly (2) is communicated with the driving wheel assembly through the reversing assembly (3). And at the second working position, the first electronic control unit (7) is electrically connected with the driving wheel assembly to control the driving wheel assembly to provide braking force. By means of the system, when a vehicle is in a normal working condition or a non-complete failure working condition, braking force is completely provided based on an electronic mechanical braking system and does not depend on a hydraulic system, and when the vehicle is in the complete failure working condition, a driver can step on a braking pedal and provide the braking force through the hydraulic system.

Description

technical field [0001] The present application relates to the field of braking equipment for vehicles, in particular to a braking system, a braking method and an automobile. Background technique [0002] The braking system is one of the important components of the car, which is directly related to the comprehensive performance of the car and the safety of life and property. The vehicle brake system has undergone several changes and improvements, from the initial leather friction brake to the drum and disc brakes, and then to the mechanical anti-lock brake system, followed by the development of electronic technology. There was an analog electronic anti-lock braking system and so on. In recent years, the research on the brake-by-wire (BBW) system has risen again. [0003] Brake-by-wire systems include electro-hydraulic brake (EHB) and electro-mechanical brake (EMB). EHB is developed on the basis of traditional hydraulic brakes, and brakes are driven by a motor through a hyd...
