Embodiment 1

[0053] This embodiment provides a vehicle tire blowout processing method, which is applied to the vehicle controller of the vehicle, such as figure 1 shown, including the following steps:

[0054] S100: Acquiring status information of each tire, and determining whether the corresponding tire has a puncture fault according to the status information. Wherein the state information of each tire can be detected by being arranged on the sensor on tire or vehicle, for example can adopt distance sensor to detect the distance from tire cover tire to wheel center, when tire is in normal state and after tire blowout, due to inner tube gas dissipate As far as possible, the distance from the tire to the center of the wheel will change. The status information of the tires may also be detected in other easy-to-implement ways. In this step, the vehicle controller can directly obtain the detection signal of the sensor, and judge whether a tire blowout occurs.

[0055] S200: If it is determi...

Embodiment 2

[0059] In this embodiment, for the implementation process of the above step S200, the following solutions are provided, such as figure 2 As shown, if it is determined that there is a tire blowout failure, the steps of starting the driving assistance system include:

[0060] S201: If it is determined that a tire has a blowout fault, output a first control signal to activate the lane keeping assist system. Because after a tire blowout occurs, the most likely problem is that the driving direction cannot be controlled. Therefore, after a tire blowout is detected, the lane keeping assist system is first activated. After the lane keeping assist system is activated, the vehicle can keep the vehicle in the lane before the tire blowout and continue to drive, so as to avoid the sudden change of the vehicle's driving direction and collide with other vehicles.

[0061] S202: Obtain the environmental information around the vehicle. The existing camera and radar of the vehicle can be used...

Embodiment 3

[0065] The vehicle tire blowout processing method that present embodiment provides, as image 3 shown, including:

[0066] S301: Acquiring the state information of each tire, and determining whether the corresponding tire has a blowout fault according to the state information.

[0067] S302: If it is determined that a tire is blown out, start the driving assistance system. That is, as long as there is a tire blowout failure, the driving assistance system will be activated immediately.

[0068] S303: Acquire the operation signal for intervening in the driving state of the vehicle and record the input time of the operation signal; the operation signal for intervening in the driving state of the vehicle is the operation performed by the driver, such as the driver stepping on the accelerator pedal, braking pedal, turning the steering wheel rapidly, etc. .

[0069] S304: Determine whether the interval between the input time and the time for activating the driving assistance syst...

Abstract

The embodiment of the invention provides a vehicle tire blow-out treatment method, device and system, a vehicle tire blow-out detecting device and electronic equipment. According to the vehicle tire blow-out treatment method, device and system, the vehicle tire blow-out detecting device and the electronic equipment, when the situation that any tire is subjected to a tire blow-out breakdown is detected, a driving auxiliary system is started instead of directly braking a vehicle, so that it is ensured that when the tire blow-out breakdown occurs, the vehicle can be continued to run under assisting of the driving auxiliary system, the driving auxiliary system can avoid sudden loss of control of the vehicle, the rear-end accident caused by sudden braking of the vehicle is avoided, and runningsafety when the tire blow-out breakdown occurs is ensured.

Description

technical field [0001] The invention relates to the technical field of vehicle intelligent control, in particular to a vehicle tire blowout processing method, device and system, a vehicle tire blowout detection device and electronic equipment. Background technique [0002] In the process of traffic travel, a flat tire is a relatively common vehicle failure. A tire blowout during high-speed driving will cause the vehicle to deviate from the normal driving direction, and the driver's reaction speed in an emergency may be greatly affected, and the vehicle cannot be controlled in time to a safe driving state. The personal safety of occupants of the vehicle may be endangered. However, the existing tire blowout processing method is to brake the vehicle after a tire blowout fault is detected. This processing method may cause the vehicle behind to collide with the car, causing a rear-end collision, especially on the expressway. When driving, it is likely to cause more serious traf...
