The invention discloses a power-assisted steering system neutral position calibration control method and system and a vehicle, and the method comprises the steps that an EPS controller judges whether the EPS zero position calibration learning state of the vehicle is valid or not, and sends an unmarked neutral position state signal to a central control screen when the EPS zero position calibration learning state is invalid; wherein the EPS controller interacts with the central control screen through an in-vehicle bus protocol; the central control screen collects a request meso-position clearing instruction triggered by a user, and controls the EPS controller to execute a meso-position clearing program; and the central control screen collects a request meso-position calibration instruction triggered by a user after the meso-position clearing program is completed, and controls the EPS controller to execute a meso-position calibration program. Compared with other methods for meso-position calibration through a diagnostic instrument, the method is more convenient, rapid and visual, the function cost is reduced, and the function integration level is improved.

    本发明公开了一种助力转向系统中位标定控制方法、系统及车辆,所述方法包括:EPS控制器判断车辆的EPS零位标定学习状态是否有效,并在所述EPS零位标定学习状态无效时向中控屏发送未标中位状态信号;其中,所述EPS控制器与所述中控屏通过车内总线协议进行交互;所述中控屏采集用户触发的请求中位清除指令,控制所述EPS控制器执行中位清除程序;所述中控屏在所述中位清除程序完成后采集用户触发的请求中位标定指令,控制所述EPS控制器执行中位标定程序。相较于其他通过诊断仪进行中位标定的方法,本发明所述方法更加便捷快速直观,降低了功能成本,提高了功能集成度。
