Electronic control of manual transmission clutch

A controller adjust a clutch actuator position is response to movement of a clutch pedal. During an engagement or a disengagement, the controller monitors sensor signals to determine the actuator position corresponding to the touch point. The sensors may directly indicate clutch torque or may respond indirectly. A Giant Magneto Resistive (GMR) sensor provides a precise shaft rotational position signal which can be twice numerically differentiated to yield an accurate and stable acceleration signal. The controller updates the touch point based on a change in the sensed acceleration or torque. The controller then adjusts the relationship of actuator pedal position to clutch pedal position, making mechanical wear adjustment unnecessary.
