The invention relates to a driving assisting device. The device emits a plurality of linear laser rays, and the linear laser rays are projected to a plane to form approximately parallel lines. The device has two usages: 1, the device is used for determining the distance between a vehicle and an obstacle; 2 is used for marking the vehicle width and other marks; for the use method 1, as shown in Figure 1, Figure 2 and Figure 3, the light rays a and b emitted by the device M intersect at the point o. And the light rays are projected onto an obstacle N to form light rays a and b. The distance s between the light a and the light b changes along with the change of the distance d between the M and the N. The device is fixed at a proper position of the vehicle, and the intersection point of the two laser rays is adjusted to be about 5-20 cm in front of or behind the vehicle (the safety limit position of advancing or retreating). When the vehicle moves forwards or backwards, the distance between the vehicle and the obstacle can be very conveniently judged only by observing the distance between the light rays projected on the obstacle. For use 2, the device is fixed at a proper position of the vehicle, light rays are projected to the road surface, or part of the light rays are projected to the road surface and part of the light rays are projected to the vehicle body, as shown in figure 8, p1p2 and p7p8 are the light rays projected to the vehicle body, and p3p4 and p5p6 are the light rays projected to the road surface. By means of vehicle width marking light on the road surface, whether vehicles can meet or pass through a squeezing road or pass through a width limiting pier can be judged.
本发明涉及一种开车辅助装置。该装置发出若干条一字形的激光线,投射到平面后形成近似平行线。该装置有两种用法:1用于确定车与障碍物的距离。2用于标示车宽与其它标记。对于用法1,如图1,图2,图3所示,装置M发出的光线a`,b`交于o点。投射到障碍物N上形成光线a,b。光线a,b的距离s会随着M,N的距离d的改变而改变。将装置固定于车的适当位置,将两激光线的交点调节于车前或车后约5~20厘米左右(前进或后退的安全极限位置)。前进或后退时,只需观察投射于障碍物上的光线之间的距离就可以非常方便的判断车与障碍物的距离了。对于用法2,将装置固定于车的适当位置,将光线投射到路面,或部分投射到路面部分投射车身,如图8所示,p1p2和p7p8是投射到车身的光线,p3p4和p5p6是投射到路面的光线。借助路面上的车宽标记光线,就可以判断能不能会车,在榨路通过,或过限宽墩了。
