Secondly, the vehicle powertrain parameters are taken as design variables and the vehicle power and economy are taken as the optimization targets, a multi-objective optimization model of the vehicle is built. The transmission parameters are optimized by the multi-objective particle swarm algorithm. the Pareto optimal solution set is obtained by calculating the optimization parameters. Finally, the optimal transmission parameters are determined by the multiple attribute decision making method based on information entropy.
