Abstract

The invention relates to the technical field of vehicle safety control, in particular to a safety control method and system for vehicle tire blowout, and a vehicle. When the vehicle has a tire blowout, the present invention determines whether the steering angle is smaller than the turning angle threshold at the current vehicle speed according to the collected steering angle signal, and when the steering angle is smaller than the turning angle threshold, the steering torque is adaptively adjusted according to the lane departure angle, so that the lane departure angle is set Within the range of angles, it can ensure that the vehicle will not deviate from the lane at a large angle, avoid the driver's control error caused by unresponsiveness or panic, reduce the possibility of the vehicle losing control, ensure the driving safety of the vehicle after a tire blowout, and avoid serious accidents. happened.

Description

technical field

[0001] The invention relates to the technical field of vehicle safety control, in particular to a safety control method and system for vehicle tire blowout, and a vehicle. Background technique

[0002] The safety of automobiles has been paid more and more attention by major automobile factories, but there are not a few traffic accidents caused by tire blowouts, especially when the vehicle is driving at high speed, tire blowouts will lead to serious accidents. Tire, mainly adopts automobile tire pressure monitoring system, namely TPMS (Tire Pressure Monitoring system) system. The TPMS system mainly determines whether the tire is abnormal through the monitoring of tire pressure and temperature, and prevents the tire from puncture. Therefore, the TPMS system can only alarm the tire due to abnormal air pressure, and does not control and intervene in the tire puncture situation during driving.

[0003] There is a patent application with a Chinese patent applicati...

Examples

Embodiment Construction

[0038] The present invention will be described in further detail below with reference to the accompanying drawings.

[0039] Method example:

[0040] The invention provides a safety control method for vehicle tire burst, such as figure 1 shown, including the following steps:

[0041] 1) Collect the tire pressure signal, and judge whether the vehicle has a tire blowout according to the tire pressure signal.

[0042] The vehicle will collect the vehicle speed in real time during the running process. When the vehicle speed is greater than the upper limit threshold of the vehicle speed, it will start to judge whether the vehicle has a tire puncture, and can judge whether the vehicle has a tire blowout according to the collected tire pressure signal. When the vehicle speed is low, if the vehicle has a tire blowout, there will not be too much danger, and it can be completely controlled by the driver. Therefore, the present invention is aimed at the tire blowout control under high ...
