The invention provides a steering wheel neutral position angle calibration method. The steering wheel neutral position angle calibration method comprises the following steps that S1, an ECU receives a calibration request; s2, judging whether a median angle calibration condition is met or not, if yes, entering the next step, and if not, ending the calibration request; s3, adjusting the angle of the steering wheel; s4, calculating a median angle value; s5, detecting whether a median angle calculation result is credible or not, if yes, entering the next step, and if not, reporting calibration failure to the ECU and ending the calibration request; s6, storing the meso-position angle data, ending the calibration request, judging whether the meso-position angle calibration condition is met or not by analyzing the engine rotating speed and the vehicle speed signal of the whole vehicle, and detecting whether the meso-position angle calculation result is reliable or not, so that the method is simple and efficient, runs through the whole vehicle steering system development process, and is high in angle calibration result credibility; and the operation performance of the system is improved.

    本发明提供了一种方向盘中位角度标定方法,包括以下步骤:S1:ECU接收标定请求;S2:判断中位角度标定条件是否满足,如果满足即进入下一步骤,如果不满足则结束本次标定请求;S3:方向盘角度摆正;S4:中位角度值计算;S5:检测中位角度计算结果是否可信,如可信则进入下一步骤,如不可信则向ECU报告标定失败结束本次标定请求;S6:保存中位角度数据,并结束本次标定请求,通过解析整车的发动机转速、车速信号,判断中位角度标定的条件是否满足,通过检测中位角度计算结果是否可靠,简单高效,贯穿整个车辆转向系统开发过程,且角度标定结果可信度高,提高了系统的操作性能。
