摘要： A method of controlling the torque transferred across the engaged clutch of a vehicle having a dual clutch transmission to provide predetermined engine acceleration for each gear based on the engine throttle position and subsequent changes of clutch speed that are in response to operatively varying the torque transferred across the engaged clutch as the engine accelerates to a predetermine speed based on the throttle position. The method includes the steps of determining the engine throttle position, determining the currently engaged gear of the transmission, and sensing the speed of the driven member of the engaged clutch. Then, a target engine speed is determined based on the engine throttle position, the currently engaged gear, and the clutch speed. The torque transferred across the engaged clutch is then continuously varied to cause the engine to accelerate toward the target engine speed.

摘要： A method of controlling the torque transferred across each clutches of a dual clutch transmission during a gear shift. The method includes the steps including determining when a shift has been commanded, sensing the speed of the driven member of the off-going clutch, determining the desired clutch torque and slip profile for the changeover of the clutches, and sensing the speed of the driven member of the on-coming clutch to determine a target engine speed profile. The method simultaneously controls the torque transfer across each clutch by linearly decreasing the torque transferred across the off-going clutch while linearly increasing the torque transferred across the on-coming clutch in an inversely proportional rate. Finally, the pressure applied to the on-coming clutch is varied, to cause the engine to continue to track the target engine speed profile so that vehicle speed is maintained.

摘要： A method of controlling the pressure applied to the engaged clutch of a vehicle having a dual clutch transmission to control the torque transferred across the engaged clutch thereby providing engine speed control for each gear based on the engine throttle position. The method includes the steps of determining the engine throttle position, determining the currently engaged gear of the transmission, and sensing the speed of the clutch. An engine stall speed is selected for the current gear and engine throttle position from a look-up table, and then a target engine speed based on the engine stall speed and the clutch speed is continuously redetermined, the clutch speed increasing in response to the increasing engine speed. The method also includes determining the difference between the target engine speed and the actual engine speed and then varying the torque transferred across the clutch driving the engaged gear to cause the engine to track the target engine speed based on the difference between the target engine speed and the actual engine speed.
