specific Embodiment approach 1

[0048] Embodiment 1: By detecting whether there is a lane-changing vehicle in the target vehicle within the speed guidance range, the speed guidance range is the range of the preset distance from the intersection; For a lane-changing vehicle, the driving state information of the target vehicle on the lane before and after the lane-changing vehicle is obtained, the driving state information at least includes: the speed and position information of the vehicle; according to the driving state information , update the guidance speed of the target vehicle on the lane before and after the lane change of the lane-changing vehicle, the guidance speed is the speed at which the signal light phase is green when the target vehicle passes through the intersection, as attached figure 1 as shown in

specific Embodiment approach 2

[0104] Specific Embodiment 2: In addition to the vehicle-road coordinated speed guidance control method described in Embodiment 1, this application can also be realized by subdividing into various modules for splicing to form a specific vehicle-road coordinated speed guidance control system. The system includes: Vehicle-road cooperative speed guidance control system, which includes roadside subsystem, vehicle-mounted subsystem and signal control unit; roadside subsystem is responsible for receiving external vehicle-road signals, and uses the roadside subsystem and vehicle-mounted subsystem to directly connect two-way communication through PC5 The vehicle-mounted subsystem feeds back to the personnel in the vehicle by receiving the communication signal from the signal control unit and the road condition information provided by the roadside subsystem; the 5G roadside CPE set by the roadside subsystem and the 5G vehicle-mounted CPE set by the vehicle-mounted subsystem are both Two...

Abstract

The invention relates to a 5G vehicle-road cooperation speed guide control method, system and device and a storage medium, belongs to the field of vehicle-road cooperation, and aims to solve the problems of short pure signal communication distance, limited communication data frame length and data frame loss at present. The 5G vehicle-road cooperation speed guide control system includes a roadside subsystem, a vehicle-mounted subsystem and a signal control unit, the roadside subsystem receives an external vehicle-road signal, and the roadside subsystem and the vehicle-mounted subsystem are directly connected through a PC5 for two-way communication; the vehicle-mounted subsystem receives a communication signal from the signal control unit and feeds back road condition information provided by the road side subsystem to a driver; the 5G roadside CPE arranged on the roadside subsystem and the 5G vehicle-mounted CPE arranged on the vehicle-mounted subsystem are both in bidirectional communication with the signal control unit through Uu ports, and a closed-loop control system is formed to complete speed guidance. Through a speed guiding algorithm, a reasonable vehicle driving speed interval is provided, the red light waiting time is reduced, the vehicle parking frequency is reduced, and the vehicle average delay time at the signalized intersection is reduced.

Description

technical field [0001] The invention relates to a speed guidance control method for vehicle-road coordination, in particular to a speed guidance control method, system, equipment and storage medium based on 5G vehicle-road coordination, and belongs to the field of vehicle-road coordination. Background technique [0002] Compared with single-vehicle intelligence, vehicle-road coordination can effectively make up for blind spots in perception, and transform autonomous driving from individual combat in the past to organized and efficient collaboration. Especially in the context of the country's vigorous promotion of new infrastructure, technology giants have deployed vehicle-road collaboration projects to accelerate the maturity of the autonomous driving industry. [0003] At present, the communication links of vehicle-road coordination are mainly traditional DSRC and LTE-V2X. Among them, on-board units (on-board unit, OBU, hardware units installed on vehicles that can realize ...
