The invention discloses a vehicle driving early warning system and method. The system comprises a geomagnetic sensor, a lane controller, a signal transmitting antenna, a micro control unit (MCU) and an intelligent central gateway (ICGM). In the early warning system, a geomagnetic sensor transmits an address identifier through a first bus, and a lane controller acquires the state and the state remaining time of a traffic signal lamp through a second bus, and transmits the state and the state remaining time of the traffic signal lamp to an ICGM through a signal transmitting antenna, a signal receiving antenna and a third bus. The ICGM sends out an early warning prompt when judging that the vehicle meets a preset condition according to the state of the traffic signal lamp, the state remaining time and the speed of the vehicle. In the system, the message is transmitted through the bus or the antenna instead of the Internet, so that the information transmission delay caused by poor Internet quality can be avoided, the accuracy of the obtained state of the traffic signal lamp is improved, and the accuracy of early warning information for a driver is improved.

    本申请公开了一种车辆行驶预警系统和方法,所述系统包括地磁传感器、车道控制器、信号发射天线、微控制单元MCU和智能中央网关ICGM。该预警系统中地磁传感器通过第一总线传递地址标识,车道控制器通过第二总线获取交通信号灯的状态和状态剩余时间,并通过信号发射天线、信号接收天线和第三总线传递交通信号灯的状态和状态剩余时间给ICGM。ICGM根据交通信号灯的状态、所述状态剩余时间和车辆的速度判断车辆满足预设条件时,发出预警提示。在本系统中,通过总线或天线传递消息,而非通过互联网传递消息,由此可以避免由于互联网质量很差出现的信息传输延时,提高了获取的交通信号灯的状态准确性,从而提高给驾驶员的预警信息准确性。
