The invention discloses a highway entrance ramp vehicle collaborative collision avoidance system and method, a cloud data center receives vehicle driving track data sent by a roadside system, predicts vehicle driving tracks of a main roadside and a ramp side, and calculates position coordinates of a virtual collision point according to the predicted driving track of the ramp side; and then the position distance between the main road side vehicle and the ramp side vehicle is calculated, the response level of the system is determined by comparing response threshold values, a cooperative collision avoidance instruction is sent out, and the vehicle-mounted intelligent system controls the vehicles to perform cooperative collision avoidance according to the cooperative collision avoidance instruction. According to the invention, the traffic collision accident rate of the expressway entrance ramp is effectively reduced, and the traffic driving safety of the expressway is ensured.
本发明公开了一种高速入口匝道车辆协同避撞系统与方法,云端数据中心接收路侧系统发送的车辆行驶轨迹数据,对主路侧和匝道侧的车辆行驶轨迹进行预测,并根据匝道侧的预测行驶轨迹计算出虚拟碰撞点的位置坐标,进而计算出主路侧车辆和匝道侧车辆的位置距离,通过比对响应阈值来确定系统响应级别,并发出协同避撞指令,车载智能系统根据所述协同避撞指令控制车辆进行协同避撞。本发明有效降低高速入口匝道汇车碰撞事故率,保证高速道路交通行车安全。
