The invention provides a driving prompting method and device. A vehicle-mounted terminal on a vehicle obtains a conversion sequence of a plurality of traffic signal lamps arranged on the same traffic signal lamp pole, the lighting time duration of different traffic signal lamps in the plurality of traffic signal lamps, and the conversion time point of any two traffic signal lamps in the plurality of traffic signal lamps. And when the vehicle runs to the area commanded by the plurality of traffic lights, a second time point ispredicted according to the information, i.e., the time point of conversion of any two colors of traffic lights in the plurality of traffic lights, and driving prompt information of the second time point is generated. By adopting the scheme, the driving prompt information is generated according to the conversion sequence of the traffic lights, so that the accuracy of the driving prompt information is improved, and accurate driving prompt information can be generated to guide a driver to drive when the vehicle is blocked by the front vehicle and the weather and the surrounding environment interfere with the identification of the traffic lights.
本申请提供一种行车提示方法及装置,车辆上的车载终端获取设置在同一个交通信号灯杆上的多个交通信号灯的转换序列,多个交通信号灯中不同交通信号灯亮起的时间长度,以及多个交通信号灯中任意两个交通信号灯转换的时间点。当车辆行驶至多个交通信号灯指挥的区域后,根据该些信息预测第二时间点,即多个交通信号灯中任意两个颜色的交通信号灯转换的时间点,生成第二时间点的行车提示信息。采用该种方案,通过根据交通信号灯的转换序列生成行车提示信息,提高行车提示信息的准确率,有助于车辆被前方车辆遮挡、天气和周边环境对识别交通信号灯造成干扰时,生成准确的行车提示信息以指导驾驶员的驾驶。
