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 accompanying drawings and specific embodiments.

[0027] Such as figure 1 As shown, the emergency treatment method after the vehicle tire blowout can 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 alignment: before the steering wheel rotates beyond a predetermined angle, the electric steering system forces the steering wheel to return to alignment according to the rotation angle information;

[0030] Release step: after the steering wheel returns to the normal position, the electric steering system releases the control of the steering wheel to allow the steering wheel to turn, and returns to perform the detection step.

[0031] figure 1 The method shown allows the driver and the electric power steering...

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, in particular to a method and system for emergency treatment after a vehicle tire blows out. Background technique [0002] A vehicle puncture refers to a situation in which a tire suddenly loses the inflated gas in the tire due to rupture in a very short period of time. The occurrence of tire blowout is often very sudden, and the time left for the driver to take remedial measures is very short, and the vehicle is often difficult to control. Under the action of huge inertial force, the vehicle undergoes severe sideslip and tail flicking. A severe tire blowout accident will cause the vehicle to roll continuously and collide with guardrails and other vehicles, resulting in extremely serious traffic accidents. [0003] The correct response after a tire blowout is to first stabilize the steering wheel, control the driving direction, step on the brakes slowly, and slowly pull over to stop. However, this met...
