Problems solved by technology

When the platoon encounters disturbances, the changing vehicle speed may affect its energy efficiency. However, most common vehicle platoon control methods are based on the fact that the vehicles in the platoon follow the lead vehicle and track the speed of the lead vehicle in real time. The phenomenon of unnecessary acceleration and deceleration increases, which leads to an increase in the energy consumption of the entire queue

Abstract

The invention discloses a method and system for optimal control of vehicle platoons, relates to the technical field of intelligent transportation, and solves the technical problem of high energy consumption in existing vehicle platoon control methods. Use the state information between the adjacent vehicle in front of the current vehicle node and the leading vehicle to construct a discrete dynamic model of the vehicle; and use the constraint transformation function to transform the distance constraint and speed constraint in the process of vehicle platoon driving, reducing the computational complexity Thereby improving the computational efficiency of Le, and each optimization problem considers the discrete dynamic model, constraint conditions and energy-saving control objective function of each vehicle, which improves the energy consumption economy of the entire vehicle platoon, and ensures the safety of the vehicle platoon. Maximize the economic benefits of energy consumption of the vehicle platoon.

Description

technical field [0001] The present disclosure relates to the technical field of intelligent transportation, in particular to a method and system for optimal control of vehicle platooning. Background technique [0002] The intelligent vehicle queue control technology refers to forming a queue of intelligent vehicles driving on the road, and through the environment perception technology, the vehicles in the queue can obtain the surrounding environment and road information. Communication technology realizes the sharing of vehicle status information between vehicle platoons, and based on this, completes the control of individual vehicle nodes in the platoon, and achieves a coordinated control technology for the stable driving of vehicle platoons as a whole. It is of great research significance to improve the overall energy consumption and economy of vehicles. [0003] Queue stability and queue energy-saving effect are two key performance indicators of intelligent vehicle platoo...
