Problems solved by technology

However, these control schemes cannot adapt to various road conditions and vehicle driving conditions.
For example, if the vehicle is on a turn when the tire blows out, locking the steering axis may cause the vehicle to go out of the lane and cause a serious accident

Embodiment Construction

[0026] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0027] Such as figure 1 As shown, the emergency handling method after a vehicle tire burst may include the following steps:

[0028] Detection steps: the steering wheel angle sensor detects the angle information of the steering wheel, and transmits the angle information to the electric steering system;

[0029] Step of returning to the right: before the steering wheel rotates more than a predetermined angle, the electric steering system forcibly returns the steering wheel to the right according to the rotation angle information;

[0030] Release step: After the steering wheel is returned to the center, the electric power steering system releases the control of the steering wheel to allow the steering wheel to rotate, and returns to perform the detection step.

[0031] figure 1 The method shown allows the driver and the electric steering system to alternately control ...

Abstract

The invention discloses a method for emergency handling of vehicle tire burst. The method is used for controlling the direction of a vehicle when a tire of the vehicle bursts in the running process, and comprises the following steps: a detecting step of detecting the turn angle information of a steering wheel and transmitting the turn angle information to an electric steering system by a steering wheel corner sensor; a returning step of forcibly returning the steering wheel by the electric steering system according to the turn angle information before the steering wheel rotates at an angle of more than the predetermined angle; and a releasing step of releasing the control of the electric steering system on the steering wheel after the steering wheel returns so as to allow the steering wheel to rotate, and returning to perform the detecting step.

Description

Technical field [0001] The invention relates to the field of automobiles, and in particular to an emergency treatment method and system after a vehicle tire burst. Background technique [0002] A puncture of a vehicle refers to a situation where the tire suddenly loses its inflated body due to rupture in a very short period of time. The occurrence of a puncture is often very sudden, and the time left for the driver to take remedial measures is very short. The vehicle is often difficult to control. Sudden puncture will seriously damage the force balance and directional control of the driving vehicle, especially in high-speed driving. Under the action of huge inertial force, the vehicle will have violent sideslip and tail flick. A serious puncture accident will cause the vehicle to continuously roll over and collide with guardrails and other vehicles, resulting in a very serious traffic accident. [0003] The correct countermeasure after a tyre burst is to first stabilize the steeri...
