Wire control brake system based on time-division serial control and simultaneous parallel control

Abstract

The invention discloses a wire control brake system based on time-division serial control and simultaneous parallel control and aims to solve the problems that a traditional brake system vacuum booster is large in size and expensive, and a motor-assisted wire control hydraulic brake system is high in motor requirements, expensive and incapable of guaranteeing precise pressure control. The wire control brake system comprises a wire control brake system body based on the time-division serial control and a wire control brake system body based on the simultaneous parallel control, wherein the wire control brake system body based on the time-division serial control comprises a brake master cylinder output unit (A) with an oil cup, a first hydraulic control unit (B1), an electronic control unit (C) and a wheel brake (D); the wire control brake system body based on the simultaneous parallel control comprises a brake master cylinder output unit (A) with an oil cup, a second hydraulic control unit (B2), an electronic control unit (C) and a wheel brake (D); that is to say, only the first hydraulic control unit (B1) and the second hydraulic control unit (B2) of the two system bodies are different.

Description

technical field [0001] The invention belongs to a brake-by-wire brake system in the technical field of automobile brake systems. More specifically, the present invention relates to brake-by-wire systems based on time-sharing serial and simultaneous parallel control. Background technique [0002] With the improvement of people's living standards and the rapid development of the automobile industry, people's pursuit of automobile technology is getting higher and higher, especially the safety technology of automobiles. Automobile safety technology is closely related to automobile braking. Traditional automobile vacuum booster braking systems are bulky, complex in structure, high in cost, and highly dependent on engines. At present, the vacuum booster system is canceled to reduce the dependence on the engine, and it has become a research trend of automobile braking to be able to actively and quickly decompress, accurately control the pressure, and not affect the pedal feeling. ...
