摘要

For hybrid electric vehicles with traction motors installed behind the transmission, motor torque can be used to compensate for traction loss during gear shift. Thus, engine speed control can be used to achieve speed synchronization without disengaging the clutch. To improve the speed tracking performance during gear shift, an engine speed control system is designed based on gain-scheduling PID and PD controllers and Smith predictor. Gain-scheduling PID and PD controllers are used to address the system nonlinearities and Smith predictor is used to compensate the intake-to-power delay. An accurate engine model is built, and the delay time of intake-to-power is identified. By intensive off-line calibration, the control settling time is less than 1 s, and the range of tracking error is 0 to +20 rpm, which satisfy the performance requirements of the synchronizer engagement during gear shift of AMT(Automated Manual Transmission).
