The embodiment of the invention relates to the technical field of vehicles, and discloses an automatic wheel aligning method and device.The method is suitable for an electric power steering system (EPS) of a target vehicle, the EPS comprises a power assisting module and a dormancy module, and the method comprises the steps that when a lower high voltage signal of the target vehicle is received, a timer is started; when the timer is not finished, if the target vehicle meets a preset wheel return activation condition, the power assisting module activates a wheel return control function, and wheels of the target vehicle are driven to return; and when the timer ends, the dormancy module responds to the lower high-voltage signal to control the EPS to enter a dormancy state. According to the technical scheme, the electric power steering system can serve as a control node, the timer is started to enable the EPS to enter the dormant state in a delayed mode, the wheels of the target vehicle are driven to return to the right position when the timer is not finished, an external controller is not needed, delay of signal transmission and signal processing can be effectively reduced, and the wheel return efficiency is effectively improved.

    本发明实施例涉及车辆技术领域,公开了一种车轮自动回正方法及设备,其中方法适用于目标车辆的电动助力转向系统EPS,EPS包括助力模块和休眠模块,包括:在接收到目标车辆的下高压信号时,启动定时器;助力模块在定时器未结束时,若目标车辆满足预设的车轮回正激活条件,则激活车轮回正控制功能,驱动目标车辆的车轮回正;在定时器结束时,休眠模块响应下高压信号,以控制EPS进入休眠状态。应用本发明的技术方案,能够以电动助力转向系统作为控制节点,启动定时器以使EPS延时进入休眠状态,在定时器未结束时驱动目标车辆的车轮回正,无需借助外部控制器,能够有效降低信号传输和信号处理的延迟,有效提高车轮回正的效率。
