Abstract: A fuel economy model was set up for the engine and on its basis the matching strategy for continuously variable transmission with the engine was studied and the relationship between engine goal rpm and vehicle speed was determined.The comprehensive control strategy was formulated from the demand on vehicle dynamic performance at transient operating conditions and fuel economy at steady operating conditions.The improved comprehensive control strategy remedies the deficiency of control strategy for best fuel economy,improves the vehicle dynamic performance at transient conditions without penalty on steady condition fuel economy.

Key words: continuously variable transmission, matching strategy, integrated control strategy
