Vehicle tyre-bursting security control method and system

Abstract

The invention relates to an automobile tyre burst safe control method and a system thereof. The method comprises the steps as follows: 1) an automobile tyre burst safe control system is established and comprises a signal collecting unit, a main control unit, a lengthways safe executing unit and a transverse safe executing unit, and all units are communicated with each other by a vehicle CAN bus; 2) when an automobile tyre bursts, the main control unit sends a control instruction to the lengthways safe executing unit and the transverse safe executing unit; 3) after receiving the control instruction, the lengthways safe executing unit closes a throttle valve by a throttle valve automatic control apparatus and drives a lengthways braking executing device to lead the automobile to reduce the speed fast; and 4) simultaneously, after receiving the control instruction, the transverse safe executing unit controls a steering auxiliary motor to lead the automobile to keep the former running direction. The invention has less difficulty to be realized, high reliability and low cost and has important practical significance and wide application prospect.

Description

technical field [0001] The invention relates to the technical field of automobile active safety, in particular to a safety control method and system for automobile tire blowout. Background technique [0002] Car tire blowout is a common dangerous situation. Every year, traffic accidents caused by car blowout account for a large proportion, especially when the car is running at high speed, it is easy to cause the vehicle to deviate from the normal driving track, thus causing major traffic accidents. . According to the traffic accident data of China's public security traffic control department, among the 389,670 traffic accidents from January to November 2005, 80,989 people died, and the accidents caused by flat tires accounted for nearly 20%. And 46% of traffic accidents in expressways are caused by tire failure, and punctures account for 70%. At present, a lot of research work has been carried out on tire pressure monitoring technology at home and abroad, and many innovati...

Problems solved by technology

Although this type of technology has a certain effect on the safe driving of the vehicle with a blown tire, the main disadvantages of this type of technology are as follows: 1. After the blown out tire, the vehicle is braked in time to slow down, but the driving direction of the vehicle is not controlled, and the control of the direction of the vehicle is still It is operated by the driver, which still cannot completely avoid traffic accidents caused by tire blowouts; 2. The vehicle hydraulic actuator has a complex structure and is expensive; 3. If the hydraulic actuator is used to control the direction of the vehicle, it will involve braking force The problem of reasonable allocation is extremely difficult to control, and it is difficult to achieve a good safety control effect for different driving conditions
