Abstract

The present application provides a method, device and system for longitudinal control of truck platoons with vehicle-road coordination. The method includes: the first edge cloud corresponding to the road section where the truck platoon is located obtains the traffic information of the road network and the basic vehicle information of the trucks in the truck platoon from the central cloud. ; The first edge cloud obtains the facility's perception information of the road surface from the corresponding roadside computing facility; the first edge cloud obtains the vehicle's perception information of the road surface and vehicle driving condition information from the truck queue; , vehicle basic information, facility perception information on the road surface, vehicle perception information on the road surface, vehicle driving condition information, and the road state information of the road section where the truck queue is obtained by the first edge cloud itself, generate a collaborative control strategy and send it to the truck queue Coordinated control strategy; the truck queue performs longitudinal control of trucks according to the coordinated control strategy. The application can obtain more comprehensive interactive information of the truck platoon, and improve the stability of the longitudinal control of the truck platoon.

Description

technical field [0001] The invention relates to the fields of automatic driving and intelligent transportation, in particular to a method, device and system for longitudinal control of truck platoons with vehicle-road coordination. Background technique [0002] With the rapid development of autonomous driving and vehicle-road coordination technology, under the background of integrated vehicle-road integration, dynamic information interaction between vehicles and vehicle-road and vehicle-road collaborative control can be realized in an all-round way. The management and control of vehicle platoons in vehicle-road cooperative control is highly concerned. The truck queue accounts for a large proportion in the management and control of the vehicle queue, so the truck queue is the focus of attention in dynamic information interaction and vehicle-road collaborative control. Truck platoon refers to multiple trucks running on the road with a short distance between vehicles through a...
