The invention discloses an emergency vehicle signal intersection vehicle speed guiding system based on vehicle infrastructure cooperation. The system comprises an emergency vehicle sensing module, a non-emergency vehicle sensing module, a vehicle speed guiding module and a signal timing adjusting module. The emergency vehicle sensing module and the non-emergency vehicle sensing module are in parallel relation, the emergency vehicle sensing module cooperates with the non-emergency vehicle sensing module after acquiring emergency vehicle driving information, sensing information is input into the vehicle speed guiding module and the signal timing adjusting module, the vehicle speed guiding module and the signal timing adjusting module carry out parallel calculation, and the vehicle speed guiding module and the signal timing adjusting module carry out timing adjustment. And generating a vehicle speed guiding strategy and a signal timing strategy to guide the vehicle to pass. According to the vehicle-road cooperation system, the corresponding vehicle passing schemes are generated when the vehicle arrives at the intersection and drives out of the intersection, vehicle conflicts can be avoided, the time of the signal lamps and the speed of the vehicles at the intersection can be adjusted, and the purpose of preferentially and rapidly passing the emergency vehicles is achieved through cooperation of the non-emergency vehicles at the intersection, the emergency vehicles and the roadside intelligent equipment.

    本发明公开了基于车路协同的紧急车辆信号交叉口车速引导系统,包括紧急车辆感知模块,非紧急车辆感知模块,车速引导模块和信号配时调整模块。紧急车辆感知模块与非紧急车辆感知模块为并行关系,紧急车辆感知模块获取到紧急车辆行驶信息后与非紧急车辆感知模块相互合作,将感知信息输入到车速引导模块和信号配时调整模块中,车速引导模块和信号配时模块并行计算,生成车速引导策略与信号配时策略,引导车辆通行。本发明在车路协同系统中,在到达交叉口与驶出交叉口时生成对应的车辆通行方案,能够避免车辆冲突,调整信号灯时间与交叉口车辆车速,通过交叉口非紧急车辆,紧急车辆与路侧智能设备的协同合作,达到紧急车辆优先快速通行的目的。
