The invention discloses a vehicle-mounted laser radar early warning system for vehicle driving, and relates to the technical field. The system comprises a vehicle-mounted laser radar, a collision early warning unit, an alarm and a vehicle-mounted power supply. The vehicle-mounted laser radar comprises a laser transmitting end, a laser echo receiving end, a scanning unit and an information processing unit; the collision early warning unit is electrically connected with the alarm and the display screen; the collision early warning unit analyzes the data information of the real-time relative displacement Li of the target to obtain a front real-time relative distance Si; when the collision remaining time t is calculated to be smaller than or equal to p1, p1 is a set fixed value, the collision early warning unit controls the alarm to be started, prompt information of collision danger is output to the display screen, a vehicle driver is reminded of early warning of collision danger, and deceleration/avoidance is prompted. According to the invention, through the effects of the vehicle-mounted laser radar and the collision early warning unit, the collision early warning of the collision remaining time and the relative acceleration of the target can carry out timely prediction and danger prompt functions.
本发明公开了一种车辆行驶用的车载激光雷达预警系统,涉及技术领域。本发明包括车载激光雷达、碰撞预警单元、报警器和车载电源;车载激光雷达包括激光发射端、激光回波接收端、扫描单元和信息处理单元;碰撞预警单元与报警器、显示屏进行电性连接;碰撞预警单元将目标实时相对位移Li的数据信息进行分析得出前方实时相对距离Si;当计算得出碰撞剩余时间t≤p1时,p1为设定的定值,碰撞预警单元控制报警器进行启动,并向显示屏输出碰撞危险的提示信息,提示车辆驾驶员遇到碰撞危险的预警,并提示进行减速/避让。本发明通过车载激光雷达和碰撞预警单元的作用,碰撞剩余时间及目标的相对加速度的碰撞预警进行及时预测和危险提示的功能。
