The invention relates to a vehicle positioning method and a controller, and relates to the field of vehicle positioning, and the method comprises the steps: obtaining a plurality of wireless ranging signals from a vehicle-mounted beacon in a vehicle-mounted device, the plurality of wireless ranging signals being sent to the vehicle-mounted beacon periodically by one or more ground devices; and determining a target moment when the vehicle-mounted beacon is closest to the ground equipment according to the plurality of wireless ranging signals. And determining the position of the vehicle according to the target moment and the position of the ground equipment. According to the invention, the position of the vehicle is determined according to the plurality of acquired wireless ranging signals, and the accuracy and anti-interference capability of vehicle positioning can be improved.

    本公开涉及一种车辆的定位方法和控制器,涉及车辆定位领域,该方法包括:从车载设备中的车载信标获取多个无线测距信号,多个无线测距信号为一个或多个地面设备周期性地发送至车载信标的。根据多个无线测距信号确定车载信标与地面设备距离最近的目标时刻。根据目标时刻和地面设备的位置确定车辆的位置。本公开根据获取到的多个无线测距信号确定车辆的位置,能够提高车辆定位的精确度和抗干扰能力。
