Abstract
Emergency shifting is performed in a shift-by-wire (SBW) vehicle during a power failure of a main electrical supply that includes a battery. A shift actuator is configured to mechanically couple to the transmission in order to execute shift events between a plurality of shift positions (including park and neutral) using the main voltage from the main supply during normal conditions. A human-powered generator is provided for converting a manually-imparted motion to an electrical output during the power failure. A storage device (e.g., capacitor) receives the electrical output to store a power reserve to apply to the shift actuator to execute an emergency shift event in the absence of main power in response to a manual command. The generator and storage device are configured such that a maximum power reserve stored from the generator can achieve only one emergency shift event at a time.
