Abstract

Official abstract text for this publication.

A method for monitoring a transmission range selector connected to a transmission of a powertrain system is described. The transmission range selector indicates one of a plurality of ranges including Park, Reverse, Neutral, and Drive. The method includes, upon detecting a change in a target transmission range, monitoring whether a signal output from an on-board sensor indicates an achieved range position of the transmission. When the signal output from the on-board sensor does not indicate that the target transmission range has been achieved, monitoring a transmission incorrect direction metric, monitoring a transmission unintended propulsion metric, and monitoring a metric associated with achieving the target transmission range. A fault is detected when any one of the transmission incorrect direction metric, the transmission unintended propulsion metric and the target range achievement elapsed time metric is exceeded.

First claim

Opening claim text (preview).

The invention claimed is: 1. A method for monitoring a transmission range selector connected to a transmission of a powertrain system, wherein the transmission range selector indicates one of a plurality of ranges including Park, Reverse, Neutral, and Drive, the method comprising: upon detecting a change in a target transmission range, monitoring, via a controller, whether a signal output from an on-board sensor indicates an achieved range position of the transmission, wherein det…
