Problems solved by technology

[0005] The invention focuses on the problem of merging prompts when vehicles line up, and solves the need to ensure that when vehicles are queuing and merging, the distance is small, the driving is slow, and the continuous multiple times of merging (a vehicle gives way the previous time and merges next time) fair question
Compared with the existing merging prompt method, the present invention does not rely on devices other than the vehicle to provide measurement and prompt, but relies on the device installed in the vehicle to be merged to complete the judgment and prompt; avoiding the complicated structure of the existing method limited installation locations and lack of flexibility

Embodiment Construction

[0025] The specific embodiments here are only used to explain the present invention, not to limit the present invention.

[0026] figure 1 The wireless communication method between the merging indicators installed on the two vehicles can achieve the purpose of establishing communication only when they are close to each other by controlling the antenna direction and transmission power.

[0027] The merging indicator can be installed at the position of the direction light at the head of the vehicle; at the same time, it is equipped with an indicator light visible to the driver of the vehicle.

[0028] Set up 3 timers:

[0029] T1: Priority hold time, the time to hold the "state" (0 / 1) of the priority merge, and the "state" is set to the initial value 0 after timeout;

[0030] T2: The cycle of sending the "request" of parallel channels, and send a "request" signal once after the timeout;

[0031] T3: After receiving the "request", the longest interval for sending a "response...

Abstract

The invention discloses a vehicle queuing and merging prompt method. The method comprises the steps: before queuing and merging, a vehicle actively sends a merging request to an adjacent vehicle; theadjacent vehicle sends response information according to an own priority status; a sender and a receiver make a judgment for the merging sequence accordingly at this time and the judgment is given toa driver; and meanwhile updating the own priority status to guarantee the fairness of the subsequent merging sequence judgment. The invention further discloses a vehicle queuing and merging prompt device. According to the vehicle queuing and merging prompt method and the vehicle queuing and merging prompt device disclosed by the invention, through wireless exchange of autonomous status informationof two vehicles, the fair merging sequence is given to prompt the driver; and on the premise of ensuring fairness, the safety of vehicle queuing and merging is improved.

Description

technical field [0001] The invention relates to a traffic control system subcategory of road vehicles in the category of traffic control systems; in particular, it relates to a vehicle merging indicating method and device. Background technique [0002] With the development of society, vehicles are becoming more and more popular in the field of transportation. In order to improve the traffic capacity of vehicles, road facilities such as expressways, overpasses, viaducts and turning lanes have been built. To enter and exit these roads, you need to go through ramps and special lanes. When the traffic volume is large, you need to line up to enter. Vehicles on the two lanes need to merge into one lane. [0003] At present, the scheme adopted by vehicles queuing and merging mainly relies on the vehicle driver to observe the sides of the vehicle through the rearview mirror, and observe the situation of vehicles in front and side through the side head; when the traffic flow is larg...
