Abstract
Official abstract text for this publication.
An electronic control unit senses an actual shift range of a automatic transmission by executing a range determination operation, which determines the actual shift range of the automatic transmission based on a rotational position of a manual shaft that is sensed with an encoder. The control unit prohibits the execution of the range determination operation throughout a range determination operation prohibiting period, which is a predetermined time period and starts from a time point of starting rotation of the rotor of the electric motor unit toward the target rotational position.
First claim
Opening claim text (preview).
What is claimed is: 1. A shift-by-wire system for an automatic transmission of a vehicle, comprising: an electric motor unit that includes a rotor, wherein the rotor is rotated when the electric motor unit is energized; a manual shaft that is rotated by a drive force outputted from the electric motor unit upon rotation of the rotor; a detent plate that includes a plurality of recesses and is fixed to the manual shaft to rotate integrally with manual shaft; a detent spring th…
