Shift quality and shift time of the automatic transmission is required to be consistent in mass production and with mileage accumulation. In order to compensate for the influence of build-to-build variations and life-cycle variations on shifting process, there should be an adaptive control in the software in addition to the base control of the shifting process. The adaptive control can adjust control...
This paper presents the application of multi-domain physical system simulation method in the study of automatic transmissions which involve mechanics, electronics, and hydraulics. Based on the multi-domain modeling and simulation tool ITI-SimulationX, the sub models of a automatic transmission are modeled and simulated in a multi-domain way, including the torque convert sub model, planetary gear sets...
