The invention provides a vehicle red light running early warning and vehicle speed control method, which comprises the following steps of: periodically receiving traffic light information sent by a preset road side unit around a current driving road of a vehicle, and obtaining state information of a traffic light with the nearest forward distance of the vehicle according to the traffic light information; according to the obtained position, the change period and the signal state of the traffic light with the nearest forward distance of the vehicle and the current driving position of the vehicle, the related time information of the current driving position of the vehicle corresponding to the signal state in the traffic light with the nearest forward distance of the vehicle in two continuous change periods is determined; and vehicle red light running early warning is carried out by combining the vehicle speed and the acceleration of the current driving position of the vehicle. According to the invention, not only is a set of complete red light running early warning algorithm defined, but also a complete suggested vehicle speed algorithm is expanded and added on the basis.
本发明提供一种车辆闯红灯预警及车速控制方法,包括周期性接收车辆当前行驶道路周边预设路侧单元所发送的交通灯信息,并根据该交通灯信息,得到车辆前向间距最近的交通灯的状态信息;根据所得到的车辆前向间距最近的交通灯的位置、变化周期和信号状态以及车辆当前行驶位置,确定车辆当前行驶位置对应该车辆前向间距最近交通灯中连续两个变化周期内信号状态的相关时间信息,并结合车辆当前行驶位置的车速、加速度,进行车辆闯红灯预警。实施本发明,不仅定义了一套完整的闯红灯预警算法,还在此基础上扩展添加了完整的建议车速算法。
