Abstract

The invention provides an automobile brake control method and system. The control method includes the steps that firstly, a windscreen wiper controller signal is obtained, and whether a windscreen wiper is turned on or not is judged; secondly, an automobile speed signal is obtained, and whether the automobile speed is larger than a speed threshold value or not is judged; and thirdly, when the windscreen wiper is turned on and the automobile speed is larger than the speed threshold value, a brake is periodically pressurized through an ABS controller. The weather condition is judged through the windscreen wiper controller signal, the current traveling state is judged through the automobile speed signal, when the conditions that the windscreen wiper is turned on and the automobile speed is relatively high are met at the same time, the brake is periodically pressurized for a short time, a brake disc can be cleaned, rainwater or snow water on the brake disc is removed, it is guaranteed that the friction coefficient between the brake disc and a brake pad is stable, so that the brake response characteristic is improved, the brake braking distance is shortened, and traveling safety on rainy days and snowy days is guaranteed.

Description

technical field

[0001] The invention relates to the technical field of automobiles, in particular to an automobile braking control method and system. Background technique

[0002] During high-speed driving in rainy and snowy weather, the friction coefficient between the brake disc and the friction plate is reduced due to the rain and snow erosion between the brake disc and the friction plate. Insufficient braking force is provided between them, resulting in increased braking distance and reduced safety. Contents of the invention

[0003] The technical problem to be solved by the present invention is to provide an automobile braking control method and system that can reduce the braking distance and improve safety in rainy and snowy weather.

[0004] In order to solve the above-mentioned technical problem, the present invention provides a kind of automobile braking control method, comprising:

[0005] Step S1, obtaining the signal of the wiper controller, and judging wheth...
