Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the embodiments.

[0019] Such as figure 1 As shown, the system of the present invention includes a plurality of suggested speed display devices 1 and an information processing device 2 . Wherein, the traffic light control network 3 transmits the current state of the traffic light 4 in front of the vehicle and the time variation rule of the traffic light to the information processing device 2, and the information processing device 2 calculates the input information, and calculates a suitable time for the vehicle to pass through the intersection in front of it. Speed ​​range, and select the actual speed range to send to the traffic light control network 3, and then the traffic light control network 3 sends the speed range to the suggested speed display device 1 for display. The suggested speed display device 1 of the present invention can simultaneously display a plurality of different suggested...

Abstract

The invention relates to a traffic light auxiliary system which comprises an information processing device and a suggested speed display device. The distance between a traffic light in the front of the vehicle and the corresponding suggested speed display device, and the update frequency of the content displayed by the suggested speed display device are pre-arranged in the information processing device; and the information processing device calculates the speed range within which the vehicle passes the front junction according to the current state of the traffic light in the front of the vehicle and the time change regulation provided by a traffic light control network, and then transmits the calculation result to the suggested speed display device through the traffic light control network, and the suggested speed display device displays the calculation result according to the update frequency. The traffic light auxiliary system can accurately provide suggested speed information to a driver, improve the traffic efficiency, reduce vehicle emission and can be widely used in traffic management systems.

Description

technical field [0001] The invention relates to the field of traffic management systems, in particular to a traffic light auxiliary system. Background technique [0002] During the driving process, the vehicle often encounters the following two situations when it is far or far away from the intersection: one is when the vehicle drives near the intersection, the traffic light suddenly changes from green to yellow or red; the other is As soon as the vehicle stopped at the intersection, the traffic light immediately changed to green. These two situations will not only waste a lot of fuel, but also generate a lot of exhaust gas during the starting and parking process of the vehicle, which will pollute the environment and limit the traffic efficiency of vehicles at the intersection. Vehicle positioning methods such as GPS have appeared in the prior art, and the vehicle-mounted computer is used to calculate a reasonable vehicle speed and display it to the driver according to the ...
