Problems solved by technology

The defective of above-mentioned scheme is obvious, and the one, the driver has the feeling of " stepping on air " when making braking response after the brake pedal is moved down, easily makes the driver produce flustered and causes an accident, the 2nd, motor starts to move down and pushes the brake pedal. It takes a long time for the master cylinder to generate braking force, and the response time of the automatic control system lags behind

Abstract

The controllable total hydraulic braking pump for automobile may be used as the executer of automatically controlled automatic reducing system. The automatically controlled automatic reducing system comprising the total hydraulic braking pump can realize automatic wear end collision preventing braking, automatic braking in tyre explosion, automatic reducing in overspeed running, etc.

Description

technical field [0001] The invention relates to an automobile self-control deceleration system composed of a controllable automobile hydraulic brake master cylinder, and relates to the technical field of automobile automatic control. Background technique [0002] With the development and progress of automobile technology, automobile automatic control technology is also developing rapidly. A very important part of automobile automatic control technology is the automatic control braking of automobiles, such as automobile anti-rear collision braking, automatic deceleration braking for punctured tires, speeding Automatic control of deceleration, etc., requires the use of devices that can be directly driven by the automatic control system as actuators. And in the automobile automatic control brake system of open technology, what adopt is to be directly pulled brake pedal by motor or electromagnetic traction electromagnet drag traction wire rope, as the technical scheme in CN20503...
