| Abstract: | In order to solve the reverse solution of parameters for a heavy truck powertrain matching design,a new optimization method for heavy vehicle transmission parameters based on PARETO optimal solutions was proposed.First,the approximate model of the vehicle’s CRUISE model is built to use as a surrogate in the process of multi-objective optimization.Then,the MATLAB genetic algorithm toolbox was used to solve the optimization problem,and a set of optimal PARETO solution was obtained for the model transmission parameters.The results show that the PARETO sets can provide many feasible solutions for the engineering staff,which is convenient to choose the appropriate transmission parameters. |
