Embodiment Construction

[0040] (1) Intelligent networked vehicle formation control method based on vehicle-road coordination

[0041] 1. Road area division of urban signal intersections

[0042] Such as figure 1 As shown in the scene, the road section is divided into three areas, including free movement area, buffer area and formation area. The first car is the leading car, and the following cars are the following cars. The vehicle establishes vehicle-to-vehicle / vehicle-road wireless communication in the buffer area, and performs vehicle speed adjustment control after entering the formation area.

[0043] exist figure 1 In the scene, the buffer area should satisfy the condition of formula (1):

[0044] δ=t r · v max

[0045] (1)

[0046]In formula (1), δ is the length of the buffer zone; t r The time required to establish a stable connection for vehicle-road communication; v max It is the maximum speed of the vehicle under the current road grade.

[0047] 2. Condition setting of formation ...

Abstract

The invention provides an automobile-road cooperation-based intelligent networked automobile formation control method and device. According to the method and device, the technical superiorities of automobile-road cooperation are utilized, multi-source traffic information is acquired and analyzed in real time, a formation control algorithm calculates an optimal automobile speed, and therefore, automobiles can run at the optimal automobile speed according to instructions under a formation state. With the automobile-road cooperation-based intelligent networked automobile formation control method and device adopted, the parking and queuing phenomena of automobiles at the intersections can be avoided, road operation efficiency can be improved, and road passage capacity can be improved.

Description

technical field [0001] The invention belongs to the technical field of vehicle-road coordination / intelligent networked vehicles, and specifically relates to a control method and device for ensuring vehicle driving safety and improving road traffic capacity through vehicle formation control based on a vehicle-road coordination environment. Background technique [0002] With the continuous development of intelligent transportation and vehicle-road coordination technology, the development of advanced information collection and information interaction technology makes real-time data fusion possible, which promotes the development of intelligent networked vehicle technology and vehicle driving system. In the wireless communication environment, intelligent networked vehicles can more easily perceive and obtain the surrounding environment and vehicle information, and conduct real-time analysis, thereby realizing vehicle-road information fusion and collaborative control.
