The invention discloses a vehicle front anti-collision system based on a drivable area. Comprising an environment sensing module, a driving area detection module, a control decision module and an execution module. A foresight camera and a laser radar on a vehicle are used for obtaining road environment information in front of the vehicle, the road environment information is processed in a drivable area detection module to obtain a drivable area and an obstacle information list in a corresponding drivable area boundary, and then the drivable area and the obstacle information list are transmitted to a control decision module; and the control decision module screens out the most dangerous target object on the driving track of the vehicle, calculates the collision time of the vehicle and the most dangerous target object in real time, obtains control decisions of different control modes according to a collision time threshold value, and transmits the control decisions to the execution module to execute collision prevention. The front anti-collision system can overcome the defect that an existing front anti-collision system only performs anti-collision on people and vehicles, can realize anti-collision on common obstacles on roads, and greatly reduces the occurrence rate of traffic accidents.

    本发明公开了一种基于可行驶区域的车辆前方防碰撞系统。包括环境感知模块、可行驶区域检测模块、控制决策模块、执行模块;通过车辆上的前视摄像头及激光雷达进行车辆前方道路环境信息的获取,在可行驶区域检测模块中处理上述道路环境信息得到可行驶区域及对应的可行驶区域边界内的障碍物信息列表,然后传输给控制决策模块,在控制决策模块中筛选出在本车行驶轨迹上的最危险目标物,并实时计算本车与最危险目标物的碰撞时间,根据碰撞时间阈值获得不同控制模式的控制决策,并将控制决策传输给执行模块,执行防碰撞。本发明能够克服现有的前方防碰撞系统只对人和车进行防碰撞,可实现对道路上出现的一般障碍物防碰撞,大大降低交通事故发生率。
