specific Embodiment approach 1

[0026] The roadside automatic driving vehicle positioning and navigation system of this embodiment, such as figure 1 As shown, the navigation system includes a set of roadside positioning and navigation units 1 and a set of on-board navigation units 2. A set of roadside positioning and navigation units 1 are arranged on the roadside, and every two adjacent roadside positioning and navigation units 1 The effective detection areas between the two overlapped each other, each car navigation unit 2 is set on an autonomous vehicle, and each roadside positioning navigation unit 1 communicates with each car navigation unit 2 in the effective detection area.

specific Embodiment approach 2

[0028] The difference from the first embodiment is that the roadside autonomous vehicle positioning and navigation system of this embodiment is such as figure 1 As shown, each of the roadside positioning and navigation units 1 includes a roadside communication module 3, a roadside positioning and navigation module 4, a roadside perception module 5, and a roadside data processing module 6. Each of the mentioned car navigation units 2 Including the vehicle-mounted communication module 7, the vehicle-mounted decision-making module 8, and the vehicle control module 9; among them,

[0029] The roadside communication module 3 is used to realize the communication interaction between the roadside positioning and navigation unit 1 and the vehicle-mounted communication module 7 of the vehicle-mounted navigation unit 2, sending the positioning information and perception information of the roadside positioning and navigation unit 1, and receiving the vehicle-mounted navigation unit 2. Informa...

specific Embodiment approach 3

[0037] Different from the second embodiment, in the roadside automatic driving vehicle positioning and navigation system of this embodiment, the roadside positioning and navigation unit 1 can also be installed on a vehicle that performs automatic driving, and is used to generate data between two parallel vehicles. In the case of occlusion, the roadside positioning navigation unit 1 installed on the occluded vehicle detects the driving information of the occluded vehicle, and the occluded vehicle can send the location perception information of the occluded vehicle to the occluded vehicle.

Abstract

The invention discloses a road side automatic driving vehicle positioning navigation system and a positioning navigation method for single and multiple vehicles, and belongs to the field of vehicle automatic driving. Existing areas, including large buildings or wharfs and the like with more sheltering objects, utilize a GNSS (Global Navigation Satellite System) and inertial navigation technology,and therefore, the problems of poor signal transmission performance and large navigation error of an automatic driving navigation system can be solved. By use of the road side automatic driving vehicle positioning navigation system and the positioning navigation method for single and multiple vehicles, the navigation system comprises one group of road side positioning navigation units and one group of vehicle-mounted navigation units, wherein one group of road side positioning navigation units is arranged on the road side, effective detection area overlapping is generated between every two adjacent road side positioning navigation units; each vehicle-mounted navigation unit is arranged on one automatic driving vehicle; and each road side positioning navigation unit and each vehicle-mountednavigation unit in the effective detection area are subjected to communication interaction.

Description

Technical field [0001] The invention relates to an automatic driving navigation technology, in particular to a system and method for navigation based on a roadside approach. Background technique [0002] Since autonomous driving can save labor costs, reduce accident rates, and reduce fuel consumption, all walks of life are currently working hard to promote development. With the development of various on-board sensor technologies and artificial intelligence technologies, autonomous driving technologies are increasingly becoming commercialized. Especially in closed and semi-closed application scenarios, such as automated terminals, airports, closed parks, etc., autonomous driving technology is hopefully the first to commercialize. [0003] The automatic driving of vehicles is mainly realized through positioning, perception, decision-making and control. At present, most of the navigation technology of autonomous vehicles uses various sensors on the vehicle, such as lidar, millimeter...
