The invention discloses a vehicle-following driving automatic cruise method and system. The method comprises the steps that a rear vehicle and a front vehicle which are in vehicle-following driving establish communication connection through a real-time communication system with the same communication protocol; the front vehicle transmits the current driving parameter information to the rear vehicle through the real-time communication system; the rear vehicle measures the real-time vehicle following distance between the rear vehicle and the front vehicle according to the real-time communication system, and adaptively adjusts the driving state of the rear vehicle and the safe vehicle distance between the rear vehicle and the front vehicle in combination with the driving parameter information transmitted by the front vehicle; by means of the automatic cruise method, the rear vehicle does not need to measure the driving state parameters of the front vehicle through a sensor, and directly receives related data from the front vehicle, so that the emergency response speed in the vehicle following driving process is greatly improved, and then the safety of self-adaptive cruise driving is improved.
本发明公开了一种跟车行驶自动巡航方法及系统,其中该方法包括:跟车行驶的后车与前车通过具有相同通信协议的实时通信系统建立通信连接;前车通过实时通信系统将其当前行驶参数信息传送给后车;后车根据实时通信系统测算与前车之间的实时的跟车距离,并结合前车传送的行驶参数信息对自身行驶状态和与前车之间的安全车距进行自适应调节;通过上述自动巡航方法,后车无需通过传感器测算前车的行驶状态参数,而是直接从前车接收相关数据,从而大幅提升跟车行驶过程中的应急响应速度,进而提升自适应巡航行驶的安全性。
