Research and Development on Testing Simulative System of Automatic Transmission Electronic Control Unit

Automatic transmission ECU (Electronic Control Unit) is the key of shifting automatically. It directly influences the shift quality and the driving amenity whether ECU can work normally. Simulation can shorten the research and development cycle and save fund. According to the peripheral parameter for automatic transmission ECU working, we simulate the road environment, research and develop the testing Simulative system of automatic transmission ECU. At the same time the shift rule and running process are put to test and analyze. The testing results gotten from the simulation system prove that it is able to satisfy and is reliable for simulating the variable rule of all automatic transmission parameter. The simulative system provides references to research and development of automatic transmission.
