Vehicle rear wheel steering control system and method

Abstract

The invention relates to the field of vehicle rear wheel control, and discloses a vehicle rear wheel steering control system and method, and the system comprises a collection module which obtains the current operation state of a vehicle in real time; a control module used for generating a corresponding target travel in real time; and an execution module which is used for determining the current vehicle condition of the vehicle according to the current running state and the target travel corresponding to the current running state, judging whether the current vehicle condition belongs to an abnormal vehicle condition or not in real time, and controlling rear wheels of the vehicle in real time according to a judgment result. The rear wheel steering control system and method have the beneficial effects that the rear wheel steering control system and method can be applied to rear wheel control under various abnormal vehicle conditions, the rear wheels of the vehicle are controlled in real time through real-time judgment of the abnormal vehicle conditions, the dynamic response characteristic of the vehicle can be improved under various abnormal vehicle conditions, and the stability of the vehicle is improved. And meanwhile, the rear wheels of the vehicle can be stably and safely controlled, the normal vehicle condition can be stably transited while safe operation of a driver is guaranteed, and then the driving experience is improved.

Description

technical field [0001] The invention relates to the field of vehicle rear wheel control, and discloses a vehicle rear wheel steering control system and method. Background technique [0002] As automobiles become more and more important means of transportation for ordinary people, people have higher and higher requirements for vehicle driving performance. For the control process of the rear wheel steering, the existing technology often buckles the rear wheels according to the driving state of the vehicle to improve the driving stability of the vehicle, however, it ignores that the driving state of the vehicle is not enough Stability, correspondingly, the control of the rear wheel steering is not precise enough to meet the safe operation of the vehicle, let alone control the vehicle to smoothly transition from abnormal vehicle conditions to safe vehicle conditions. Contents of the invention [0003] In view of the above-mentioned problems existing in the prior art, a vehicl...
