The invention relates to a track plotting method and system in a parking process and a vehicle. The track plotting method comprises the following steps: acquiring steering wheel sensor data and wheel rotating speed data of a target vehicle; according to the steering wheel sensor data and the wheel speed sensor data, the vehicle rear axle center turning radius and the vehicle driving distance per unit time are determined; according to the turning radius of the center of the rear axle of the vehicle and the driving distance per unit time of the vehicle, position coordinates of the center point of the rear axle of the vehicle are calculated. According to the method disclosed by the embodiment of the invention, the automatic parking track is obtained by calculating the wheel speed signal and the steering wheel angle signal which are acquired by the sensor, and the parking track of the vehicle is calculated only by using the data information acquired by the sensor and based on the corresponding relationship among the physical quantities in the coordinate system; therefore, the calculation result is not influenced by the environment condition and the vehicle running road condition, the advantages of being convenient to implement, low in cost and high in accuracy can be achieved, and a guarantee is provided for the safety of automatic parking.

    本发明涉及一种泊车过程中的航迹推算方法、系统及车辆,通过获取目标车辆的方向盘传感器数据和车轮转速数据;根据所述方向盘传感器数据和所述轮速传感器数据确定车辆后轴中心转弯半径和车辆单位时间行驶距离;根据车辆后轴中心转弯半径和所述车辆单位时间行驶距离推算得到车辆后轴中心点的位置坐标。本实施例公开的方法通过对传感器采集得到的轮速信号、方向盘转角信号进行推算,得到自动泊车的航迹,由于本实施例仅利用传感器采集到的数据信息和基于坐标系中各个物理量之间的对应关系推算出车辆的泊车航迹,因此推算结果不受环境状况和车辆运行路况的影响,可以取得实施方便,成本低,准确性高的优点,为自动泊车的安全提供了保障。
