Abstract

Official abstract text for this publication.

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.

First claim

Opening claim text (preview).

What is claimed is: 1. Apparatus for a vehicle having an electronically-shifted transmission, comprising: a main electrical supply including a battery providing a main voltage; a shift actuator receiving the main voltage and configured to mechanically couple to the transmission to execute shift events between a plurality of shift positions including a park position and a neutral position; a human-powered generator converting a manually-imparted motion to an electrical output;…
