| Abstract: | The optimal matching of automobile powertrain can greatly improve the power performance and economy of the vehicle. Study is done with the utilization ratio of driving power and the oil consumption at the cycle of maltiworking conditions as the objective functions of the power performance and the economy performance respectively, and then the two objective functions are transformed to a single one by using the weighted linear combination. The automobile powem＇ain parameter is optimized by genetic algorithm. A calculation example shows that the comprehensive performance of the automobile has been remarkably promoted, and shows its correctness and practicability. |
