  7. 如权利要求6所述的车用HUD显示方法，其特征在于，步骤S2中偏移量的计算方法为：The vehicle HUD display method according to claim 6, wherein the calculation method of the offset amount in step S2 is:
    步骤S21，依据驾驶员眼睛的坐标点和最佳观看视角对应的角度构建一条向下倾斜的直线，并以此直线作为当前位置驾驶员眼睛的最佳观看视线；Step S21, constructing a downwardly inclined straight line according to the angle corresponding to the coordinate point of the driver's eye and the optimal viewing angle, and using the straight line as the best viewing line of sight of the driver's eyes at the current position;
    步骤S22，计算最佳观看视线与初始HUD显示器的显示画面或其延展平面的交点，作为调整后HUD显示器的显示画面的中心点；Step S22, calculating an intersection of the optimal viewing line of sight and the display screen of the initial HUD display or its extension plane as a center point of the display screen of the adjusted HUD display;
    步骤S23，计算调整后HUD显示器的显示画面的中心点与当前HUD显示器的显示画面的中心点各轴向的距离；并以该距离作为偏移量调整HUD显示器的显示画面的位置。In step S23, the distance between the center point of the display screen of the adjusted HUD display and the center point of the display screen of the current HUD display is calculated; and the position of the display screen of the HUD display is adjusted by using the distance as the offset.
  8. 如权利要求7所述的车用HUD显示方法，其特征在于，调整HUD显示器的显示画面位置的动作触发的条件为：眼皮动作控制，或手势控制，或语音控制。The vehicle HUD display method according to claim 7, wherein the condition for triggering the action of adjusting the position of the display screen of the HUD display is: eyelid motion control, or gesture control, or voice control.
  9. 如权利要求8所述的车用HUD显示方法，其特征在于，当计算得到调整后HUD显示器的显示画面的中心点超过HUD显示器的显示画面可调整范围时，以对应轴向调整方向边界的交点为最终调整后HUD显示器的显示画面的中心点。 The method for displaying a HUD for a vehicle according to claim 8, wherein when the center point of the display screen of the adjusted HUD display exceeds the adjustable range of the display screen of the HUD display, the intersection of the direction boundary is adjusted corresponding to the axial direction. To finally adjust the center point of the display of the HUD display.
