Adjusting device and method for preventing automobile instability due to high-temperature tire bursting

Abstract

The invention discloses an adjusting device and method for preventing automobile instability due to high-temperature tire bursting and belongs to the field of electronic control systems of automobilesafety. The adjusting device comprises a sensor module, an electronic control unit, an automobile state adjusting device and an alarm lamp. Through information exchanging of electric signals between devices, quick response is conducted to change the automobile traveling state so as to change the air pressure of a tire. The original steering action of a driver can be kept, the automobile speed is decreased, the situation that due to the overlarge tire pressure, the driver conducts operating mistakenly and thus stability is lost is avoided, meanwhile the change amplitude of the automobile speedis small, and the traveling safety is guaranteed. The invention further discloses the adjusting method. According to the adjusting method, the tire pressure can be monitored in real time when an automobile travels at the high temperature, and according to the traveling environment, the traveling posture of the automobile is changed to control the tire pressure of the automobile so as to prevent the automobile instability due to tire bursting.

Description

technical field [0001] The invention relates to the field of electronic control systems for automobile safety, in particular to a device and method for preventing high-temperature tire blowout instability of automobiles. Background technique [0002] When the car is running in a high-temperature environment, the air pressure of the car tires is likely to rise due to the influence of the road surface temperature. When the rise is small, the impact on the driving safety of the car is small. When the tire pressure is too high, it is easy to cause a blowout Accidents, and when the car is running at a certain speed, a tire blowout accident will cause the car to lose stability. In this case, it is difficult for the driver to adjust the state of the car, and the probability of an accident will increase. [0003] In order to solve the above-mentioned problem of tire blowout accidents, based on the existing domestic research foundation, Chery Automobile Co., Ltd. proposed a front tir...

[0002] When the car is running in a high-temperature environment, the air pressure of the car tires is likely to rise due to the influence of the road surface temperature. When the rise is small, the impact on the driving safety of the car is small. When the tire pressure is too high, it is easy to cause a blowout Accidents, and when the car is running at a certain speed, a blowout accident will cause the car to lose stability. In this case, it is difficult for the driver to adjust the state of the car, and the probability of accidents increases.

[0003] In order to solve the above-mentioned problem of tire blowout accidents, based on the existing domestic research foundation, Chery Automobile Co., Ltd. proposed a front tire blowout anti-tracking device and its control method (authorization number CN102009572A), including the control device installed in the car The tire pressure sensor and the blasting device installed in the front tires on both sides of the car will use the explosive device to quickly and actively destroy the unexploded tire on the other side when one tire blows out, and release the gas in the tire. The radius of the front wheels on both sides tends to be the same again, but this device requires a certain amount of pressure relief time when the tire on the other side bursts, and it is easy to cause accidents within the range of time difference

[0004] Zhang Gengsheng of Luoyang Refining and Chemical Hongli Chemical Co., Ltd. invented an automatic tire pressure balance device for vehicle tires (authorization number CN102865394A), which includes a seat tube, a tee pipe and a valve. This pressure relief device releases excess air pressure to achieve the effect of run-flat tires. However, when the car is running at high speed, the change of tire pressure will cause the driving posture of the tire to change. When the car is running at high speed, this will affect the overall performance of the car. The driving state has a great impact, which is likely to cause car accidents

[0005] He Feilong of Wuhan University of Science and Technology invented a tire blowout system (authorization number CN205930060U), which includes a tire mechanism, cooling and heating components, and a signal control unit. The control unit is connected to the cooling and heating components for controlling cooling The start and stop of the heating function and the cooling or heating function conversion of the two cooling and heating conversion parts, the device realizes the controllability of the tire pressure through components, but the device consumes a lot of energy, and the change of the tire structure affects the performance of the car. driving stability
