Embodiment Construction

[0017] In order to make the purpose, technical solutions and advantages of the application clearer, the application will be further described in detail in conjunction with the accompanying drawings and specific embodiments below. The schematic embodiments of the application and their descriptions are used to explain the application and do not constitute Undue limitation of this application.

[0018] Such as figure 1 As shown, an automobile brake control system includes an acquisition module, a first determination module, a second determination module, a third determination module, and a control module.

[0019] The acquisition module includes an adhesion coefficient acquisition module, a speed sensor, and a vehicle body acquisition module. The adhesion coefficient acquisition module is used to obtain the road surface peak adhesion coefficient of the current road collected by the car in real time and the current distance between the car and the obstacle in front; the speed sens...

Abstract

The invention discloses a car braking control system comprising an acquisition module, a first determining module, a second determining module, a third determining module and a control module. The acquisition module comprises an attachment coefficient collection module, a speed sensor and a car body collection module. The first determining module determines the maximum safety braking deceleration. The second determining module calculates a current deceleration limit value during emergency braking of a car. The third determining module determines the braking alarm distance and the safety braking distance of the car according to the maximum safety braking deceleration and the deceleration limit value. The control module compares the current distance of the car with the braking alarm distance and the safety braking distance of the car and controls the car to brake according to the comparison result. The situation that braking is too late, and consequently the car collides with an obstacle or a car in front of the car can be avoided, and meanwhile a braking stability failure caused by the fact that the height of a car body is not considered during emergency braking of the car body at a bend is avoided.

Description

technical field [0001] The invention belongs to the technical field of vehicle brake control, in particular to an automobile brake control system. Background technique [0002] In recent years, the road traffic safety situation has become more and more severe. According to statistics, among numerous traffic accidents, accidents caused by rear-end collisions account for the majority, especially rear-end collisions on expressways. However, rear-end collision accidents are mostly due to the fact that when the vehicle in front brakes urgently, the vehicle behind cannot quickly know and judge and deal with it in a timely manner. Ensure vehicle safety. [0003] At present, the braking control of the vehicle is generally performed according to the road surface with a high adhesion coefficient. The braking deceleration when the speed reaches the high-adhesion road surface. If the brake is still performed according to the corresponding warning distance and safety distance threshold...
