A tire blowout safety control system suitable for electric vehicles

Abstract

The invention discloses a tire burst safety control system suitable for an electric vehicle. The electric vehicle can perform integrated control over a chassis through a line control technology. Four steering motors control four-wheel independent steering, and four hub driving motors control four-wheel independent driving and can provide a reverse rotation driving force and achieve a regenerative braking function; the height of a four-wheel independent controllable suspension can be independently adjusted; and a four-wheel electronic mechanical brake control unit controls braking force of each wheel. Tire state information can be sent to a vehicle control unit of the vehicle in real time through a sensor of a tire pressure monitoring system. A vehicle-vehicle communication intelligent technology is adopted for the vehicle, tire burst danger information is transmitted to other driving vehicles within a secondary collision hidden danger range, safety of surrounding vehicles is improved under the conditions that it is ensured that the safety of the electric vehicle subjected to tire burst is controllable, traffic accidents and damage to pedestrians are reduced, and traffic efficiency and safety are improved. The control system comprises an information collecting module, a decision control module and an execution module.

Description

[0001] The invention belongs to the field of automobile active safety, and specifically proposes a tire blowout safety control system suitable for electric vehicles, aiming at improving the stability and safety of electric vehicles after a blowout, and avoiding harm to pedestrians after a blowout of an electric vehicle Potential safety hazards and avoiding secondary collisions and traffic accidents with other vehicles, reducing hidden dangers of traffic congestion and improving traffic efficiency. technical background: [0002] According to relevant data survey statistics, more than 70% of traffic accidents on the expressway are caused by high-speed automobile tire blowouts, and drivers who lack experience in emergency handling of tire blowouts will cause car crashes and fatalities if the driver makes a wrong operation. There will be a rear-end collision, and the car with a flat tire will collide with the surrounding vehicles to cause more serious traffic accidents. Therefore, ...

AI Technical Summary

Problems solved by technology

[0007] The electric vehicle tire blowout safety control system described in the technical proposal considers the surrounding environment of the electric vehicle with a blown tire, and the vehicle-vehicle communication system is included in the execution module. The electric vehicle adopts the intelligent technology of vehicle-vehicle communication. When the tire pressure monitoring system monitors the In the event of tire burst information, by using the wireless communication network and GPS positioning system to establish communication with the surrounding vehicles with secondary collision hazards, the precise location, speed, acceleration and moving direction of the vehicle with the burst tire will be sent in real time, so that the surrounding vehicles can Take control measures in time to improve traffic safety, and at the same time avoid the secondary damage caused by the collision of the surrounding vehicles to the electric vehicle with the blown tire, solve the traffic hidden danger problem caused by the blown tire of the car, and improve the traffic efficiency and safety
