Abstract
A pressure control method of shift was proposed for the dry dual clutch transmission. The pressure control model of dry dual clucth was established, and shift strategy in different stages of shift process was proposed. The clutch target torque and cylinder target pressure in different stages of shift process were obtained based on shift jerk, and the pressure control of dry dual clutch was realized. The validity of shift pressure control was verified through the real vehicle shift tests. The speed changed gentlely without distinct impact in the real vehicle shift tests. The results show that the shift pressure control of dry dual clutch transmission can meet the requirements of rapidness and ride during the shift process.
