Abstract: In order to evaluate the drivability in the early stage of vehicle performance development, GT-SUITE software is used in this paper to establish the passenger vehicle drivability simulation model with consideration of the engine transient response and torque control strategy. The simulation model is used to simulate some typical driving conditions, and the model is corrected by test data to ensure that the simulation error is within 10%. Taking a 6-gear automatic transmission gasoline vehicle as an example, according to the different requirements of three driving modes, the throttle characteristics and the shifting schedule are calibrated virtually respectively. Finally, the virtual calibration results are verified by experiments, and the error between the simulation and testis within 8%, which fully verifies the effectiveness and practicability of the virtual calibration of drivability

Key words: drivability, transient response, torque control strategy, virtual calibration, GT-SUITE
