  • Split electronic transmission range selection systems and methods with electronic button shifter
    Patent number: 9334948
    Abstract: A system for selecting a transmission range in a vehicle includes a plurality of range selection buttons configured to individually select corresponding ones of a plurality of ranges. A plurality of sensing circuits are configured to generate sense signals based on positions of corresponding ones of the plurality of range selection buttons. A park range selection button is configured to select a park range. A park sensing circuit is configured to generate sense signals based on a position of the park range selection button. A button state module is configured to output state signals corresponding to the plurality of range selection buttons based on the sense signals from the plurality of sensing circuits. A control module is configured to select a range based on the sense signals from the park sensing circuit and the state signals from the button state module.
