Abstract

The invention provides an automobile brake control system which comprises a pressurization module in an automobile electronic stability control system, a first detection module and a control module. The first detection module is used for detecting and outputting the vacuum degree in a vacuum booster to the control module. The control module is used for judging whether the vacuum degree in the vacuum booster is smaller than the preset threshold value of the vacuum degree when the control module receives an automobile brake signal, sending a pressurization command if the vacuum degree in the vacuum booster is smaller than the preset threshold value of the vacuum degree, and ending the brake control if the vacuum degree in the vacuum booster is not smaller than the preset threshold value of the vacuum degree. The pressurization module is used for conducting pressurization so as to control a brake to execute brake according to the pressurization command sent by the control module. The pressurization module in the automobile electronic stability control system is utilized for achieving automobile brake performance compensation under the specific operation condition and improving the utilization rate of the automobile electronic stability control system, and in addition, according to the brake control system, the invention further provides a control method.

Description

technical field [0001] The invention relates to the field of braking of automobiles, in particular to an automobile braking control system and a control method. Background technique [0002] As an important technology in the field of automobile technology, automobile brake control is related to the safety performance of automobiles. The vacuum booster brake system uses the vacuum of the engine manifold to achieve vacuum boost, but it is often caused by insufficient vacuum under certain working conditions. Automobile braking control performance declines; the methods used to improve automobile braking performance in the prior art include: jet valves, electric auxiliary vacuum pumps, electrohydraulic master cylinders, electric vacuum pumps or mechanical vacuum pumps. There are requirements for the minimum vacuum of the engine, which cannot completely solve the braking performance degradation caused by insufficient braking vacuum under specific working conditions; the electric...
