Vehicle and traffic light two-way information exchange controller

Abstract

The invention discloses a vehicle and traffic light two-way information exchange controller. A traffic light intelligent module is connected with a vehicle-mounted intelligent module through a wireless communication module, an input end and an output end of the traffic light intelligent module are respectively connected with a central processing unit (CPU) module and a signal switch module among traffic lights, an output end of the traffic light intelligent module is connected with an input end of a driving circuit, and an output end of the driving circuit is connected with input ends of the traffic lights. The vehicle and traffic light two-way information exchange controller has the advantages that a traffic light system is not controlled by a fixed program, the time for a red light or a green light in each direction can be determined by collected driving direction information of each vehicle and the traffic flow according to information transmitted from every adjacent crossing, and the traffic lights transmit the information collected at the crossing of the traffic lights to adjacent crossings, can collect road condition information of every adjacent road, can transmit the traffic flow information of every adjacent road to a driver in each vehicle, and can display the best running speed or the best running time of each vehicle for passing the next crossing.

Description

[0001] Technical field: [0002] The present invention relates to a control circuit, more precisely, it relates to a controller for two-way information exchange between vehicles and signal lights, which reasonably allocates the duration of road traffic signals according to current road condition information, and realizes traffic lights controlling signal lights according to traffic flow and similar signals . Background technique: [0003] In today's society, with the improvement of people's living standards, there are more and more motor vehicles, and at the same time, traffic congestion is becoming more and more serious. Traditional traffic lights are gradually unable to adapt to the current traffic situation. Traditional traffic lights are mostly controlled by fixed programs. Regardless of the size of the traffic flow, the traffic lights can be switched according to the preset time. This method is very unscientific and causes a lot of waste. In the intersection area...
