    Abstract
  • The control strategy of CVT transmission ratio, the power performance and fuel economy of vehicle on long uphill highway were analyzed. Multiple work points between the best dynamic and best economical rotational speeds of engine at equal interval were selected, and the influence of transmission ratio of every working point on the power performance and the fuel economy was studied. The optimal control strategy of CVT transmission ratio under considering the two properties was found by Simulink simulation. Simulation result indicates that the acceleration response time of the optimal control strategy decreases by 1.2 s compared with the best dynamic control strategy, the fuel consumption rate of the optimal control strategy decreases by 7.9% compared with the best economical control strategy, and the acceleration curve is smooth. Therefore, the two performances of vehicle on long uphill highway can be effectively improved by using the optimal control strategy of transmission ratio. 3 tabs, 12 figs, 14 refs.
