A heterogeneous vehicle queue distributed energy-saving control method- based on MPC

Abstract

The invention discloses a heterogeneous vehicle queue distributed energy-saving control method based on MPC. The method includes 100, constructing a heterogeneous vehicle queue ;200, constructing a distributed heterogeneous queue energy-saving control method framework comprising an energy-saving control and a vehicle following controller; 300, designing an energy-saving controller; Step 400, determining the economic vehicle speed of each vehicle in the heterogeneous vehicle queue; 500, designing a car following control; 600, clarifying that division of labor among the vehicle controllers in the heterogeneous queue; Step 700, allowing each vehicle in the heterogeneous vehicle queue to travel according to the economic vehicle speed provided in step 400 without road gradient; and, in the caseof road gradients, allowing each vehicle in the heterogeneous vehicle queue to travel at the current economical vehicle speed provided by the following steps. The control method provided by the invention can achieve the following and stability control of the heterogeneous vehicle queue and simultaneously realize the energy-saving control of the heterogeneous queue under the condition of acquiringthe road information, and the method can effectively reduce the energy consumption of the vehicle queue.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to an MPC (Model Predictive Control)-based distributed energy-saving control method for heterogeneous vehicle platoons. Background technique [0002] With the rapid development of my country's economy, it has become the focus of the industry to realize the transformation and upgrading of the logistics industry to reduce costs and increase efficiency. Among them, road transportation is an important form of transportation. In my country, the fuel consumption rate of road transportation is still far behind that of developed countries. In addition, the development of fuel vehicles and vehicles has brought enormous pressure to the environment. To solve this problem, developing new energy vehicles and improving the same-sex efficiency of roads are effective ways to save energy. [0003] Making the vehicles drive in a platoon can shorten the following distance, effectively reduce...

Problems solved by technology

This situation is not common in real life. Even vehicles of the same type will have different vehicle weights due to different cargo loads, which will have a greater impact on the acceleration performance of the vehicle during highway driving. , resulting in unstable factors of platoon driving or the excessive following distance in the queuing, so that non-queuing vehicles on the road have the opportunity to insert into the queuing, thus affecting the overall stability of the queuing
