Abstract
A cooperative vehicle-infrastructure system, including: a road side facility, an on-road vehicle, and an on board map server The system includes a road side map processor converting absolute elevation information of roads around the road side facility into road side map-based relative elevation representations according to peripheral road network information of the road side facility; an on board map processor converting absolute elevation information of roads around the vehicle into on board map-based relative elevation representations according to peripheral road network information of the vehicle; the on board map server communicating with the road side map processor and the on board map processor, updating and maintaining a conversion relationship between the road side map-based relative elevation representation and the on board map-based relative elevation representation of the same road, and synchronizing an updated conversion relationship to the on board map processor.
