The invention discloses a road rear-end collision prevention early warning system in a foggy day environment, which comprises an environment data acquisition module, a vehicle-mounted control module and an early warning information processing module, and is characterized in that the environment data acquisition module is used for acquiring real-time weather data and front vehicle data; the vehicle-mounted control module is used for collecting real-time own vehicle data; the early warning information processing module is used for judging whether early warning information needs to be sent or not based on real-time weather data, preceding vehicle data and own vehicle data; the vehicle-mounted control module is further used for receiving the early warning information sent by the early warning information processing module and conducting early warning. The invention further discloses a road rear-end collision prevention early warning method in the foggy day environment. The driver is guided to execute the driving strategy in different traffic states, the vehicle following driving safety is effectively improved, rear-end collision accidents caused by braking of the front vehicle are reduced, and the traffic efficiency and the urban road traffic safety are improved.

    本发明公开了一种雾天环境下的道路防追尾预警系统,包括环境数据采集模块、车载控制模块、预警信息处理模块,环境数据采集模块用于采集实时的天气数据和前车数据;车载控制模块用于采集实时的自车数据;预警信息处理模块用于基于实时的天气数据、前车数据、自车数据判断是否需要发送预警信息;车载控制模块还用于接收预警信息处理模块发送的预警信息并进行预警,本发明还公开了一种雾天环境下的道路防追尾预警方法,本发明通过对前车交通状态以及自车当前状态的实时监视和跟踪,引导驾驶员在不同交通状态下执行驾驶策略,有效提高跟车行驶安全性,减少了由于前车制动造成的追尾事故,提高了交通效率和城市道路交通安全。
