Abstract
Matching analysis of automatic transmission fluid (ATF) and the hydraulic control system is an essential work for the development of ATFs used in automatic transmissions. Based on the hydrodynamic theory, an ATF model was built. By adopting the modeling concept of combining and establishing models with basic elements, the hydraulic control system model was built, and then complete matching model was built by introducing the ATF model into it. The matching level of the ATF and the hydraulic control system was evaluated, and the key parameters which influence the performance of the hydraulic control system and their proper values were defined, which will be reference for developing optimal ATFs. With the bench test result and vehicle test result on road, the matching method and models for ATFs with the hydraulic control system are confirmed to be effective and feasible, which can significantly shorten the development cycle of ATFs.
