Sensor system for the control of an automatic transmission

A sensor system for a control device of an automatically shiftable transmission with automatic manually shifted transmission, the system comprising:

• a shift selector lever movable in at least one shift gate for setting at least the positions Forward, Neutral, Reverse, and Park stop, and a position for manual shifting with an at least one position for the manual upshifting and/or a position for the manual downshifting of the gears of the transmission;
• first sensor elements, each first sensor element of said sensor elements being associated with a respective one of said positions;
• a first signal transmitter arranged at said shift selector lever to detect the position of said shift selector lever, said first sensor elements and/or said first signal transmitter being arranged to detect a positioning of said shift selector lever at least between the positions Forward, Neutral and/or Reverse, wherein the detection of a positioning of said shift selector lever at least between the positions Forward, Neutral and/or Reverse positions includes a dimensioning and/or the design of said first sensor elements and/or of said first signal transmitter to provide a first detection overlap area formed between the positions Forward and Neutral as well as a second detection overlap area formed between the positions Neutral and Reverse, further comprising second sensor elements each second sensor element of said second sensor elements being associated with a respective one of said positions of said shift selector lever, and a second signal transmitter arranged at said shift selector lever.

A sensor system for the control device of an automatically shiftable transmission, the system comprising:

• a shift selector lever movable in at least one shift gate for setting at least a forward position, a neutral position, a reverse position, and a park position;
• a plurality of first sensor elements, each first sensor element of said plurality of first sensor elements being associated with a respective one of said forward position, neutral position, reverse position, and park position;
• a signal transmitter arranged for movement with movement of said shift selector lever to detect the position of said shift selector lever at a respective said sensor element, each said sensor element and/or said signal transmitter being disposed relative to each other and relative to said shift lever to form detection overlap areas between said forward position and said neutral position and between said reverse position and said neutral position to detect a positioning of said shift selector lever at least between said forward position and said neutral position and between said reverse position and said neutral position;
• a plurality of second sensor elements, each second sensor element of said plurality of second sensor elements being associated with a respective one of said forward position, neutral position reverse position, and park position;
• and
• a second signal transmitter arranged for movement with movement of said shift selector lever, said second sensor elements and/or said second signal transmitter being disposed relative to each other and relative to said shift lever to form detection overlap areas between said forward position and said neutral position and between said reverse position and said neutral position to detect a positioning of said shift selector lever at least between said forward position and said neutral position and between said reverse position and said neutral position.

A sensor system for a control device of an automatically shiftable transmission with automatic manually shifted transmission, the system comprising:

• a shift selector lever movable in at least one shift gate for setting at least the positions Forward, Neutral, Reverse, and Park stop, and a position for manual shifting with and at least one position for the manual upshifting and/or a position for the manual downshifting of the gears of the transmission;
• first sensor elements respectively associated with each possible position;
• a first signal transmitter arranged at said shift selector lever to detect the position of said shift selector lever, said first sensor elements and/or said first signal transmitter being arranged to detect a positioning of said shift selector lever at least between the positions Forward, Neutral and/or Reverse;
• second sensor elements respectively associated with each possible position of said shift selector lever;
• and
• a second signal transmitter arranged at said shift selector lever, wherein a main measuring track is formed by said first sensor elements, and a redundancy measuring track is formed by said second sensor elements and two of said first sensor elements are associated with the position Forward in the main measuring track and one of said second sensor elements is associated with the position Forward in the redundancy measuring track.
