Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] The present invention designs a vehicle-road cooperative assisted driving method based on a road grid system, which is characterized in that: the method includes:

[0023] A. According to traffic conditions and vehicle statistical characteristics, divide the road into forward and horizontal grids according to appropriate accuracy, and assign numbers to the grids;

[0024] B. Multiple sets of video monitoring equipment are deployed at designated heights on the roadside, for example, installed at designated heights of street lamps, or integrated on multi-functional smart street lamps. Each group of monitoring equipment is composed of multiple cameras to achieve vision coverage of a certain range of front and rear sections. The field of vision of nearby monitoring equipment has a certain intersection with each other;

[0025] C. Real-time identif...

Abstract

The invention relates to a vehicle-road cooperation auxiliary driving method based on a road surface grid system; the method is characterized by comprising the following steps: A, dividing a road into grids in forwarding and lateral directions; B, arranging a plurality of groups of video monitoring devices on roadsides, wherein each group of monitoring devices are formed by a plurality of cameras, thus realizing visual field coverage in certain road section scope; C, monitoring vehicles in a visual field domination area in real time, determining vehicle occupied road grids, transmitting vehicle positions and grid occupation information between the plurality of monitoring devices in real time, and determining the vehicle positions and sizes according to the vehicle occupied road grids; D, transmitting the road surface grid information to a plurality of vehicles in real time, and combining with the vehicle auxiliary driving system so as to cooperatively determine mutual position relations and relative speed vectors of surrounding vehicles. The method can grid the existing road so as to provide a fixed coordinate system for vehicle real time positioning determination, and the grid occupied distribution conditions can serve as simplified indexes, thus providing high efficiency support for vehicle-road cooperation works.

Description

technical field [0001] The invention relates to the field of assisted driving of vehicles, and is an assisted driving method based on a road grid system and using roadside multi-point monitoring equipment to work interactively with vehicles. Background technique [0002] With the continuous advancement of sensing technology, vehicle control technology, cloud computing technology and wireless communication technology, vehicle assisted driving technology represented by assisted driving and automatic driving has developed rapidly. According to the location of the equipment and its responsibilities, vehicle assisted driving technology can be divided into vehicle-side technology, road-side technology, and vehicle-road coordination technology. [0003] The vehicle-side technology uses various images and sensing devices carried by the vehicle itself to identify and judge the surrounding conditions through the calculation of the vehicle-mounted computer, and then control the operati...
