Abstract
A transmission position encoder for a vehicle having a transmission, a transmission controller and a transmission shifter adapted to shift the transmission and reposition the transmission position encoder, the transmission position encoder comprising: a plurality of detectors for providing a plurality of signals to the controller, said plurality of signals corresponding to discrete positions of the transmission position encoder wherein the controller is adapted to determine if there is a failure in any one of the detectors as the transmission position encoder transitions from a single position to one other position.
Claims27
A transmission position encoder for a vehicle having a transmission, a transmission controller and a transmission shifter adapted to shift the transmission and reposition the transmission position encoder, the transmission position encoder comprising:
- a means for providing a plurality of signals to the transmission controller corresponding to positions of the transmission position encoder, the transmission position encoder being manipulated into discrete positions by the transmission shifter wherein the transmission controller is adapted to determine if there is a failure in said means as the transmission position encoder transitions from a single position to one other position.
A bit map for a transmission position encoder having a plurality of sensors for a vehicle having a transmission, a transmission controller and a transmission shifter adapted to shift the transmission from any one of the following states of the transmission:
- park, reverse, neutral, drive, and any one of a plurality of gear positions comprising drive, the transmission shifter is also adapted to reposition the transmission position encoder, the bit map comprising:
- a plurality of states corresponding to the position of the plurality of sensors of the transmission position encoder, wherein each of the plurality of states changes as the transmission is shifted from park to reverse and wherein at least two of said plurality of states are changed in any other shifting sequence of the transmission;
- wherein said plurality of states are provided as signals to the transmission controller.
A transmission position encoder for a vehicle having a transmission, a transmission controller and a transmission shifter adapted to shift the transmission and reposition the transmission position encoder, the transmission position encoder comprising:
- a plurality of detectors for providing a plurality of signals to the controller, said plurality of signals corresponding to discrete positions of the transmission position encoder wherein the controller is adapted to determine if there is a failure in any one of the detectors as the transmission position encoder transitions from a single position to one other position.
An absolute position encoder and system for detection of discrete positions within a transmission of a vehicle, comprising:
- a transmission controller and a transmission shifter adapted to shift the transmission and reposition a transmission position encoder;
- and
- a means for providing a plurality of signals to the transmission controller, said plurality of signals corresponding to discrete positions of the transmission position encoder wherein the controller is adapted to determine if there is a failure in said means as the transmission position encoder transitions from a single position to one other position.
