In order to improve the performance of the cars, an optimization algorithm of transmission parameters that take into account automotive dynamic and fuel economy based on genetic algorithm was presented in the paper. Firstly, the origin underway accelerate time was chose as the dynamic target function, and the 100 kilometers fuel consumption of 15-cycle driving was used to evaluate fuel economy, and the two objectives functions were putted into a comprehensive objective function. Then, the constraints were established using the requirement of automobile power performance and transmission design, and the genetic algorithm was adopted to do the optimization. At last, a simulation experiment was design to confirm the validity and effectiveness of the proposed method.
