Abstract:

A method of distributed feedback linearization controller was proposed to improve the lane-change stability of heterogeneous freight vehicle platoon on highway. Taking the heterogeneous freight vehicle platoon composed of trucks and tractor-semitrailers as the research object, a high-speed lane changing path planning set was established with use of Gaussian distribution fitting method, and the motion characteristics of the vehicle platoon during high-speed lane changing was analyzed with considering the communication delay and dynamic difference. A nonlinear system dynamics model of heterogeneous freight vehicle platoons was constructed, an active control strategy for safe lane changing of vehicle platoons was proposed, and a distributed feedback linear controller was designed. Using VTD and Matlab/Simulink, a high-speed lane changing traffic scene was established and simulated. The results show that the distance change between two adjacent vehicles is less than 1%. Therefore, the controller can ensure the track tracking and stability of the heterogeneous freight vehicle platoon.
