The invention relates to a method for optimizing a vehicle to acquire traffic light colors and countdown information. The method comprises the following steps: acquiring data of the vehicle; triggering a timing state according to the vehicle speed; triggering red light time calculation according to the position relation between the vehicle position and the intersection stop line when the vehicle stops; calculating a traffic light period according to the red light time; the traffic light color and countdown information of the intersection can be obtained without establishing communication connection with a cloud big data platform for common vehicles which are not connected to the network; for vehicles which are not equipped with cameras, radars and the like and have no perception ability, the traffic light color and countdown information at the intersection can be obtained without self sensors; traffic light data estimation is carried out for a cloud big data platform, a large amount of traffic data of different vehicles is not needed as a calculation basis, and traffic light color and countdown information can be calculated based on driving data of one vehicle; lane-level traffic light colors and countdown information can be displayed.

    本发明涉及一种优化车辆获取红绿灯灯色及倒计时信息的方法,获取车辆自身数据;根据车辆速度触发计时状态;根据车辆停止时车辆位置与路口停止线之间的位置关系触发红灯时间计算;根据红灯时间推算红绿灯周期;本发明针对普通未联网车辆,无需通过与云端大数据平台建立通信连接,也可以获取路口红绿灯灯色及倒计时信息;针对未装备摄像机、雷达等无感知能力的车辆,无需通过自身传感器,也可以获取路口红绿灯灯色及倒计时信息;针对云端大数据平台进行红绿灯数据估算,不需要不同车辆大量通行数据作为计算依据,可基于一个车辆行驶数据进行红绿灯灯色及倒计时信息的计算;可以显示车道级红绿灯灯色及倒计时信息。
