Problems solved by technology

[0003] The TPMS system mainly monitors tire pressure and temperature to determine whether the tires are abnormal and prevent tire blowouts. Therefore, the TPMS system can only generate alarms for tires due to abnormal air pressure, and does not control and intervene in the situation of tire blowouts during driving.

Embodiment Construction

[0043] The steering system of a vehicle in the prior art mainly includes a steering mechanism (a mechanical column or a mechanical steering gear), a torque sensor, a rotation angle sensor, a controller, a booster motor, and a reduction mechanism (worm gear or rack and pinion). The working principle is: the driver operates the steering wheel, the torque sensor outputs the torque signal, and the controller calculates the drive current value that needs to be provided to the booster motor through the detected vehicle speed signal, torque signal, ignition signal, engine speed signal, etc., and the booster motor Provide power to the steering mechanism to drive the wheels to turn, so as to realize the steering of the vehicle.

[0044] Based on the existing steering system, the present invention realizes the function of preventing the impact of vehicle tire blowout during driving and ensuring stable driving by adding corresponding sensors and control units.

Abstract

The invention relates to the technical field of vehicle manufacturing, and discloses a steering system and a protection method for vehicle tire burst. The steering system comprises a storage unit and a control unit. The storage unit is used for storing the corresponding relationship of the vehicle speed and tire burst protection parameters. The control unit judges that tire burst happens or not according to the change rate of the tire pressure and the inverse force moment borne by a tire from the ground. When tire burst happens, the tire burst protection parameters matched with the vehicle speed are acquired from the storage unit, and an assisted motor is controlled to transmit assistance power to a steering mechanism according to the tire burst protection parameters; and the angle of a steering wheel is kept not changed within the time of duration of providing the assistance power, and vehicle deflection is prevented from being caused by tire burst impacts. Control and interference on the tire burst situation happening during vehicle moving are achieved, stable driving is guaranteed, and the vehicle safety factor is increased; and implementation is convenient, vehicle modification is simple, and the development period is short. Meanwhile, by means of the automatic tire burst detection manner, the control and interference efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a steering system and a protection method for vehicle puncture. Background technique [0002] The safety of automobiles has been paid more and more attention by major automobile factories, but there are many traffic accidents caused by automobile tire blowouts, especially when the car is running at high speed, tire blowouts will lead to serious accidents. Tires, mainly adopt the automobile tire pressure monitoring system, that is, TPMS (Tire Pressure Monitoring system) system. [0003] The TPMS system mainly monitors the tire pressure and temperature to determine whether the tire is abnormal and prevents the tire from blowing out. Therefore, the TPMS system can only generate an alarm for the tire due to abnormal air pressure, and does not control and intervene in the situation of the tire blowout during driving.
