Development of a Powertrain Real-Time Model Based on the Assembly Characteristic

Abstract:

With consideration of changing in the powertrain degree of freedom at the actual conditions in all possible conditions, the automotive powertrain system is divided into four phases with application of the finite state machine phase concepts. The torque converter lockup clutch friction state judgment method is given, and the degree of freedom of each phase with the changing of system is analyzed. The powertrain system real-time model and integrated virtual test environment considering the dynamic response of shifting are built. Simulation test is conducted and compared with the CarSim vehicle model. The simulation results show that this model meet the modeling accuracy requirements, and the use of virtual experiment platform can effectively reduce the time and cost of validation testing.
