System and method for preventing automobile from running off due to single wheel brake failure or blown tire

Abstract

The invention discloses a system and method for preventing a car from running off due to a single wheel brake failure or a tire blowout, including a braking system, which includes a controller, a first displacement sensor, a second displacement sensor, a pressure sensor, a first displacement sensor, and a second displacement sensor. First solenoid valve, second solenoid valve, third solenoid valve, fourth solenoid valve, first brake oil circuit, second brake oil circuit, front connecting oil circuit, rear connecting oil circuit, drum brake, disc brake ; The present invention is based on sensor detection technology and hydraulic control technology, inventing a braking system; using sensor technology to monitor tire pressure and braking effect; using electromagnetic control technology to control the brake oil circuit, which can quickly realize oil circuit switching; When a single wheel brake fails or a tire blows out, the car can maintain part of the braking force and ensure that the braking force on the left and right sides is equal, which solves the current problem of braking deviation or deviation caused by a single wheel brake failure or a single tire blowout. Tail flick and other issues.

Description

technical field [0001] The invention belongs to the technical field of automobile braking, and in particular relates to a system and a method for preventing automobiles from running off due to single wheel brake failure or tire blowout. Background technique [0002] Braking is one of the main performances of a car. The evaluation index of braking performance includes three aspects: braking performance, the constancy of braking performance and the directional stability of the vehicle during braking. The directional stability of the vehicle during braking is often evaluated by the ability of the vehicle to travel on a given path during braking. The performance of the first two performances is mainly reflected in the braking distance of the car, while the stability of the braking direction of the car is specifically reflected in whether the car can drive according to the driver's driving intention. [0003] If the braking force on both sides of the car is inconsistent, it wil...

AI Technical Summary

Problems solved by technology

[0003] If the braking force on both sides of the car is inconsistent, it will cause the car to deviate during the braking process; during the braking process, if a single wheel hydraulic line is squeezed or collided and the brake fluid or compressed air cannot pass through, Or the occurrence of rust or excessive dirt and blockage will cause the brake system of the wheel to fail, so that the braking force of the tires on the left and right sides of the car will be inconsistent and the brake will deviate.

It is extremely harmful, and a little carelessness may cause serious consequences

[0004] A tire blowout when the car is running at high speed is a very dangerous situation. In this case, the driver will generally slam on the brakes. At this time, slamming on the brakes will cause the braking force of the car to be unbalanced and cause deviation. In severe cases Can cause tail flicking or even rollover
