Commercial vehicle formation strategy based on density clustering
The total fuel consumption will only decrease when the increased fuel consumption during formation is less than the reduced fuel consumption during platoon operation.In order to form a commercial vehicle platoon with fuel saving potential,this paper proposes a density clustering based commercial vehicle formation strategy.First,the commercial vehicle model in Trucksim was used to collect fuel consumption data,and an equivalent fuel consumption model was established through fitting and simplified in the distance domain;Second,utilizing the optimization problem of two vehicle formation to obtain formation standards with fuel saving potential;Then,in density clustering,the dispersed commercial vehicles are clustered into sub platoon clusters using this standard,and the optimal equivalent fuel consumption function is defined to determine the final platoon form.Finally,the effectiveness and superiority of the formation strategy proposed in this paper were verified through co-simulation.
