Abstract
A method for determining a transmission range selection of a shift-by-wire system, which includes a shift lever, a park button, and a controller, is provided. The shift lever is movable between a plurality of transmission range positions, each corresponding to a transmission range, and a null position. The park button is switchable between a pressed position corresponding to a Park transmission range, and a released position. The method includes determining, by the controller, if at least one predetermined condition exists. If it does, then the controller determines the transmission range selection to be the Park transmission range. Otherwise, the controller determines the transmission range selection to be the transmission range corresponding to the transmission range position in which the shift lever is positioned.
