Embodiment 1

[0032] figure 1 It shows the position relationship diagram of the vehicle, the traffic light and the signal transmitting unit of the present invention.

[0033] Such as figure 1 As shown, a traffic control system suitable for unmanned vehicles to pass through traffic lights 2 intersections, including: a signal transmitting unit 3, adapted to send information on the sequence of traffic lights 2 to the vehicle 1; and an unmanned vehicle installed in the vehicle 1 A driving control device, which is used to obtain the current speed of the vehicle 1 and the travel distance between the vehicle 1 and the stop line at the intersection where the traffic light 2 is located, and judge the vehicle speed according to the current speed, travel distance and received bright sequence information. 1. Whether it is possible to pass through the intersection at the current vehicle speed, so as to make a vehicle speed maintenance instruction or a braking instruction to slow down and slow down to t...

Embodiment 2

[0049] The working method of the traffic control system on the basis of Embodiment 1 includes: the unmanned driving control device is adapted to determine whether the vehicle 1 can operate at the current speed by acquiring the current vehicle speed, driving distance, and information on the sequence of traffic lights 2 Pass through the intersection to give a vehicle speed maintenance instruction or a braking instruction to slow down and slow down to the intersection to stop.

[0050] Figure 5 A flow chart of the method of operation of the access control system is shown.

[0051] Such as Figure 5 As shown, specifically, the working method is as follows:

[0052] Step S100, obtaining data for estimating whether the vehicle 1 can pass the intersection at the current speed, that is, the current speed of the vehicle 1 obtained by the unmanned driving control device and the travel distance between the vehicle 1 and the intersection where the traffic light 2 is located, And the r...

Abstract

The invention relates to an unmanned vehicle passing control system for traffic light intersections and an operating method thereof. The system comprises a signal emitting unit and an unmanned driving control device. The signal emitting unit is adaptive to transmitting lighting sequence information of traffic lights in a wireless manner; the unmanned driving control device is used for acquiring the current speed of the vehicle and the driving distance between the vehicle and a parking line of the intersection where the traffic light located and judging whether the vehicle can pass the intersection or not in the current speed according to the current speed, the driving distance and the received light sequence information so as to transmit a command of remaining the vehicle speed or braking command of decreasing the speed to brake at the intersection. The system is not only adaptive to unmanned vehicles but also benefits driven vehicles, whether a vehicle at the current position and speed can pass the front intersection with the traffic light can be judged accurately, and audio and image alarms are provided to a driver timely.

Description

technical field [0001] The invention relates to the traffic field, in particular to a traffic control system for unmanned vehicles at traffic light intersections and a working method thereof. Background technique [0002] At present, unmanned driving technology has become an important direction of automobile development. The traffic situation at the intersection of traffic lights is the most complicated, especially in rainy and foggy weather, or driving behind a large vehicle, it is more difficult to accurately judge the road situation ahead. How to make driverless vehicles safely and efficiently pass through traffic light intersections is a key issue in driverless technology and a technical problem in this field. Currently, unmanned driving technology mainly relies on camera image recognition technology, radar detection technology, and laser, infrared and other ranging technologies to judge road conditions. There is no traffic control system that is suitable for un...
