Summary:The invention discloses a simulation method and device for transfer characteristics of an automobile power system, and the method comprises the steps: determining an initial transfer function of the torque and rotating speed of the power system according to the structure of the power system and the physical process of the transmission of the power system; applying a pulse torque to the input end of the power system to obtain the rotation speed change of an output shaft, determining a system time domain response result, determining parameters of the initial transfer function, determining the transfer function, and establishing a power system transfer characteristic model; and inputting a torque demand of a to-be-tested power system into the power system transmission characteristic model to obtain a simulation result of rotation speed change. The performance of the vehicle power transmission system can be simulated and evaluated, and the problem that the drivability cannot be simulated and evaluated in the earl
