The embodiment of the invention relates to the field of head-up display equipment, and discloses a wheel track display method and device, head-up display equipment and a vehicle. The method comprises the following steps: acquiring a steering wheel rotation angle and a track circle center when a steering wheel rotates; acquiring an actual steering angle of a wheel according to the steering wheel angle; calculating a first steering angle of a front left wheel and a second steering angle of a front right wheel based on the vehicle body parameters and the actual steering angles of the wheels; constructing a first driving track of the front left wheel and a second driving track of the front right wheel based on the first steering angle, the second steering angle and the track circle center; and displaying the first driving track and the second driving track. When a driver rotates the steering wheel, the driver can visually see the tracks of the left and right wheels of the vehicle on the head-up display device, the position of the vehicle does not need to be observed only through rearview mirrors, and the driver can conveniently adjust the position of the vehicle by comparing the tracks of the left and right wheels with the relative position of the real lane line and/or the road edge through naked eyes.

    本申请实施例涉及抬头显示设备领域,公开了一种车轮轨迹显示方法、装置、抬头显示设备及交通工具。所述方法包括:获取方向盘转动时的方向盘转角,以及轨迹圆心;根据方向盘转角,获取车轮实际转向角度;基于车身参数和车轮实际转向角度,计算前左轮的第一转向角度和前右轮的第二转向角度;基于第一转向角度、第二转向角度和轨迹圆心,构造前左轮的第一行驶轨迹和前右轮的第二行驶轨迹;显示第一行驶轨迹及第二行驶轨迹。本申请的驾驶员在转动方向盘时,可以在抬头显示设备上直观看到车辆左右轮的轨迹,无需只依赖后视镜来观察车辆位置,通过肉眼对比左右轮轨迹和真实车道线和/或路沿的相对位置,便于驾驶员调整车辆位置。
