The invention discloses a wheel positioning method and a tire pressure monitoring system, and the method comprises the steps: obtaining a compensation phase representing a difference value between a measurement angle position and a fixed angle position of a rotation plane where a wheel is located directly reflected by a fixed magnetic value of the wheel in a current driving direction before positioning, and carrying out the positioning of the wheel according to the magnetic value and the compensation phase, and the position of the target wheel in the vehicle is determined according to the absolute angle position of the wheel obtained from an anti-lock braking system of the vehicle. Thus, no matter in which direction the vehicle runs, the compensation phase can be dynamically compensated, the fixed angle position of the rotation plane where the tire pressure monitoring system is located in the current direction can be truly and correctly obtained, then the precise positioning function is achieved, and the robustness of judging the angle position of the tire pressure monitoring system in the rotation plane can be improved.

    本发明公开了一种车轮定位方法以及胎压监测系统,通过在定位前获得表征车轮在当前行驶方向下的固定的磁力值直接反应的车轮所在旋转平面的测量角度位置与固定角度位置的差值的补偿相位,并根据磁力值、补偿相位,以及从车辆的防锁死刹车系统中获取的车轮的绝对角度位置,确定目标车轮在车辆中所在的位置。这样,无论车辆在什么方向行驶,都可以通过动态的补偿该补偿相位,真实正确地得出当前方向胎压监测系统所在旋转平面的固定角度位置,进而实现精准定位的功能,即能够增加判断胎压监测系统在所在旋转平面的角度位置时的鲁棒性。
