Description
Technical Field
The utility model relates to an intelligent driving technical field especially relates to a current pedestrian of vehicle crosses street traffic light crossing system.
Background
At present, the method of sending traffic light timing signals to unmanned/automatic driving vehicles by adopting a V2X (vehicle-to-outside information exchange) technology mainly comprises the following two methods:
1. the Traffic light signal is directly read by adopting a SCATS (Sydney Coordinated Adaptive Traffic control System) signal machine, and then the signal is broadcasted to nearby vehicles through a V2X intranet through data transmission with RSU (road side unit) equipment, so that unmanned/automatic driving vehicles can decelerate or accelerate in advance at the intersection and pass through the intersection of the Traffic light. However, in the practical application process, the traffic light data needs to be directly called by the SCATS annunciator, and a relevant management department is relatively abstaining from the traffic light data, so that the application difficulty is high;
2. adopt traffic signal lamp to gather the board and study the level signal of traffic lights, the signal lamp is gathered the voltage variation of board through the light colour, can acquire the light colour state of current signal lamp, then through periodic collection voltage signal operation, goes to study the signal lamp timing information of current phase place light colour, after the conversion cycle through 1 ~ 2 complete red, yellow, green like this, can be accurate study the timing information of current crossing signal lamp. Through the learned color matching of each lamp, the remaining time of the signal lamp can be calculated according to the periodically collected voltage signals, then the data is transmitted to the RSU equipment, and the traffic signal is broadcasted in the air through the V2X related standard. However, the signal lamp timing of the pedestrian street-crossing traffic light signal system is irregular, the traffic light state can be changed only when the pedestrian street-crossing trigger button is triggered, otherwise the pedestrian traffic light is always kept in the red light state, and if a standard signal lamp timing learning method is adopted, the problem that the signal lamp timing is not matched with the actual signal lamp timing can occur.
Therefore, the two methods are not suitable for accurately identifying the traffic light signals at the pedestrian crossing traffic light intersection by the unmanned/automatic driving automobile.
