The invention relates to a vehicle automatic driving assistance system, which comprises a signal analysis device arranged at the tail part of a vehicle and used for sending a first analysis command when sensing that a sound signal with a frequency corresponding to the buzzing of an ambulance exists in a traffic environment where the tail part of the vehicle is located; and the distance setting mechanism is used for triggering a safe distance setting operation for keeping a set distance or more from the nearest vehicle around when the object identification signal is received. The vehicle automatic driving assistance system is intelligent, flexible and controllable in operation. An evading mechanism can be introduced into the automatic driving vehicle, when the ambulance object nearby is intelligently detected, the safe distance setting operation which is more than the set distance with the nearest surrounding vehicle is triggered, and only when the sound signal with the frequency corresponding to the ambulance buzzing sound exists in the traffic environment where the tail of the vehicle is sensed, the ambulance buzzing sound is generated. And intelligent detection of the ambulance object is executed, so that intelligent ambulance avoidance and system power consumption saving are both considered.

    本发明涉及一种车辆自动驾驶辅助系统,所述系统包括:信号分析器件,设置在汽车尾部,用于在感应到汽车尾部所在的交通环境存在救护车蜂鸣声对应频率的声音信号时,发出第一分析命令;距离设定机构,用于在接收到对象鉴别信号时,触发与周围最近车辆保持设定距离以上的安全距离设置操作。本发明的车辆自动驾驶辅助系统运行智能、灵活可控。由于能够在自动驾驶车辆内引入规避机制,并在智能检测到附近存在救护车对象时,触发与周围最近车辆保持设定距离以上的安全距离设置操作,以及仅仅在感应到汽车尾部所在的交通环境存在救护车蜂鸣声对应频率的声音信号时,方执行救护车对象的智能检测,从而兼顾救护车智能规避和系统功耗节省。
