Abstract
A shift control device for an automatic transmission comprises a shift control member configured for manipulation by an operator to control a shift mechanism of a vehicle transmission, and an artificial feel mechanism coupled to the shift control member for providing tactile feedback. The artificial feel mechanism comprises a sensor, a controller, and a piezoelectric element. The sensor is configured for detecting a position of the shift mechanism and sending a signal that is indicative of the position. The controller is configured for receiving the signal, determining a control voltage, and providing the control voltage to the piezoelectric element. The piezoelectric element is configured and arranged so as to receive the control voltage and to apply a mechanical force that depends upon the control voltage and that is configured and applied so as to mechanically resist movement of the shift control member relative to the shift control bracket.
