    Abstract
  • The power upshift control strategy of torque-assist automated mechanical transmission (AMT) is researched. A torque-assist mechanism is equipped in the traditional AMT of commercial vehicle, which is made up of an assist clutch and automated control unit. The dynamic model of torque-assist AMT is established. According to the evaluation criterion of the shift process, the power upshift control strategy is developed. The simulation research is carried out based on the state from the second gear to the third gear, and the vehicle test is taken to verify the validity of the control strategy. The simulation and test results show that the torque-assist AMT can output power during the shift process and improve the shift quality.
