本发明公开了一种隧道入口处车辆碰壁预警系统,包括车辆异常轨迹预警装置、速度计算与触发装置和主动缓冲装置;车辆异常轨迹预警装置设置于隧道入口前,主动缓冲装置设置于隧道入口处的立墙上,速度计算与触发装置设置于车辆异常轨迹预警装置和主动缓冲装置之间;车辆异常轨迹预警装置用于对偏离正常车道车辆的驾驶员做出报警提醒;速度计算与触发装置用于对驶回正常车道的车辆解除报警,或对未驶回正常车道的车辆判断是否启动主动缓冲装置。本发明还公开了一种隧道入口处车辆碰壁预警方法。本发明技术方案在司机驶出正常车道初期,先采用声音和灯光提醒预警,在提醒预警后,判断车辆仍有撞壁风险的情况下启动主动缓冲装置对车辆进行缓冲保护。

    The invention discloses a tunnel entrance vehicle wall collision early warning system which comprises a vehicle abnormal track early warning device, a speed calculating and triggering device and an active buffering device, wherein the vehicle abnormal track early warning device is arranged in front of a tunnel entrance, the active buffer device is arranged on a vertical wall at the tunnel entrance, and the speed calculating and triggering device is arranged between the vehicle abnormal track early warning device and the active buffering device; the vehicle abnormal track early warning device is used for giving an alarm for a driver of the vehicle deviating from the normal lane; and the speed calculating and triggering device is used for releasing the alarm for the vehicle driving back to the normal lane or judging whether the active buffering device is started or not for the vehicle not driving back to the normal lane. The invention further discloses a tunnel entrance vehicle wall collision early warning method. According to the technical scheme, in the early stage of driving out of the normal lane, sound and light are adopted for reminding and early warning, and after reminding and early warning, the active buffering device is started to conduct buffering protection on the vehicle under the condition that it is judged that the vehicle still has the wall collision risk.
