Auxiliary braking system for preventing automobile sideslip

Abstract

The invention provides an auxiliary braking system for preventing an automobile sideslip. The system comprises a signal acquisition module, a signal processing module, a central control unit, a braking mechanism drive module, at least two vacuum braking mechanisms and an ESP system. The system can monitor the motion state of a traveling automobile in real time and generate a vacuum braking mechanism braking strategy matched with the current motion state of the automobile through signal analysis, the system can be matched with a main braking system of the automobile, auxiliary braking operationis executed through an intelligent control mechanism, the braking distance is remarkably reduced, and the stability and safety of traveling braking can be effectively improved; and meanwhile, the ESPsystem is fused into the auxiliary braking system, the automobile can maintain the optimal stability under various conditions, and the risk of the automobile sideslip happening under the condition ofover-steering or over-braking is reduced.

Description

technical field [0001] The invention relates to the technical field of automobile braking, in particular to an auxiliary braking system for preventing automobile sideslip. Background technique [0002] In recent years, as the number of domestic automobiles has increased year by year, road traffic safety has become more and more severe. According to the research, in many traffic accidents, rear-end collisions account for more than 70% of the total accident rate, especially on expressways, which cause more rear-end collisions, causing more serious losses of personnel and property. The rear-end collision accidents are mostly caused by the rear car running at high speed unable to stop the car in a short distance when the front car is braking in an emergency. [0003] At present, the existing automobiles are all equipped with an ABS system, the purpose of which is to prevent the wheels from locking up under emergency braking conditions, so as to ensure that the adhesion between ...

Problems solved by technology

However, since these auxiliary braking devices do not have intelligent control functions, they do not consider the impact of the braking force on the driving state of the vehicle during the braking process, resulting in the vehicle overturning due to excessive braking force, or due to braking. The power is too small to stop the car within a safe distance, which will still cause traffic accidents and bring new safety hazards to driving

[0005] In addition, when the vehicle is in an emergency, when the traditional mechanical brake device (hand brake and foot brake) is used to brake, because it only applies a large braking force to the rear two wheels, even if the ABS anti-lock braking system is installed, it will The phenomenon of vehicle tailing due to rear wheel locking is a great potential safety hazard; the key factor lies in the shortcomings of the ABS system itself, which is a passive braking system that cannot actively identify the presence of vehicles in advance Potential safety hazards, often when the driver is aware of the existence of danger, it is difficult to avoid accidents
