Auxiliary cooperative vehicle infrastructure driving system and method

Abstract

The invention relates to an auxiliary cooperative vehicle infrastructure driving system and a method. The system comprises road side equipment and vehicle equipment, wherein the road side equipment comprises a laser detection module, a communication module and a road side main control module, the vehicle equipment is mounted on vehicles and is connected with a vehicle computer, the laser detection module is used for detecting objects in a first detection scope to acquire the vehicle road condition information of each vehicle in the detection scope and transmitting the information to the road side main control module, the road side main control module is used for determining the vehicle road condition information corresponding to each vehicle, communicating with each vehicle equipment in a first communication scope through the communication module and transmitting the vehicle road condition information to the vehicle equipment of the corresponding vehicles, and the vehicle equipment is used for transmitting the received vehicle road condition information to respective corresponding main control computers. Through the system and the method, the precise road condition information can be provided for automatic driving vehicles or auxiliary driving vehicles, and data support is provided for path planning and pass strategies of the vehicles.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a vehicle-road cooperative driving assistance system and method. Background technique [0002] With the continuous development of assisted driving and automatic driving technology, the supporting vehicle-road cooperative assisted driving system has received more and more attention. A comprehensive vehicle-road collaborative assisted driving system can not only provide vehicles with information such as location, distance, and speed, but also provide vehicles with traffic meeting / following warnings, red street light information, and pedestrian traffic detection for vehicles at complex traffic intersections. However, the technical solutions of the current vehicle-road cooperative driving assistance system are mostly GPS-based vehicle-mounted terminals or roadside-based video detection equipment. Although GPS-based vehicle-mounted terminals can accurately locate t...

AI Technical Summary

Problems solved by technology

Although the vehicle-based terminal based on GPS can accurately locate the vehicle position and obtain the location information of surrounding vehicles through vehicle-to-vehicle communication (V2V) or vehicle-to-road communication (V2R), the coverage of GPS signals is limited and cannot be used indoors, in tunnels or near tall buildings. Ensure a stable communication connection, and cannot detect the driving state of non-motorized vehicles and pedestrians at complex intersections; roadside-based video detection equipment can obtain vehicle information, pedestrian information, and traffic light information
