Shifting control for automated manual transmission shifter

A transmission shifting method with clutch and accelerator pedal control using shifter and pedal actuators for the automatic operation of a manual transmission gear shift mechanism in an automotive vehicle, the automotive vehicle having a plurality of manual transmission shift positions, including first, second and third gears, wherein said actuators are used to control the shifting of gears and speed of a vehicle according to a predetermined drive cycle, said shifting method including the steps of:

• determining an engagement point for the clutch,
• recording actuator positions to control the speed of the vehicle,
• moving the clutch pedal to the engagement point with the clutch pedal actuator,
• recording the clutch actuator position and establishing that the clutch is disengaged,
• moving the gear shift actuators to the desired gear,
• recording the gear shift actuator position and establishing that the desired gear position is achieved,
• controlling the clutch and accelerator pedal actuators with sufficient frequency to achieve a desired speed for the vehicle during any shifting operation so as to be able to follow closely the prescribed vehicle speed of the predetermined drive cycle,
• gear upshifting from first gear position to second gear position,
• gear upshifting from second gear position to third gear position,
• gear downshifting from third gear position to second gear position,
• initiating acceleration from idle including releasing the clutch relatively slowly,
• initiating deceleration to an idle speed,
• controlling a coasting condition for the vehicle, and
• using open loop accelerator pedal control during shifting.
