    • An optical system for aiding the driver of a vehicle in judging the proximity of the forward end of the vehicle to an object directly in front of the vehicle, particularly when parking close to a wall or barricade or when pulling up close to another vehicle stopped at an intersection. An illuminated target and a mirror mounted beneath opposite sides of the dashboard are used to reflect an image of the target off the interior surface of the windshield at a location so that the reflected image is in the normal field of view of the driver. A virtual image of the target is perceived by the driver to emanate from a position above the forward end of the vehicle. The driver may gradually advance the vehicle until the virtual image appears to the driver to be juxtaposed with the object at which time there will be a predetermined minimum safe distance between the forward end of the vehicle and the target.
    • 一种光学系统,用于在车辆前方判断车辆前端与车辆前方的物体的接近程度,特别是当停靠在靠近墙壁或路障的地方,或者当靠近另一辆停在 一个十字路口 被照射的目标和安装在仪表板的相对侧下方的反射镜被用于将位置上的目标物的图像从挡风玻璃的内表面反射出来,使得反射的图像处于驾驶员的正常视野内。 目标的虚拟图像被驾驶员感知到从车辆前端上方的位置发出。 驾驶员可以逐渐前进车辆,直到驾驶员看到虚拟图像与对象并置,此时车辆前方与目标之间将存在预定的最小安全距离。
