Patent ID: 6935203

Claim:
A system for determining a gear selection utilizing a selection lever in an automatic transmission, the system comprising: at least two units for detecting the selection lever position generating respective signals corresponding to the detected selection lever position; means for evaluating said signals to determine the gear selection based on said signals while considering plausibility rules; wherein, with a first one of said signals and a second one of said signals, which correspond to different selection lever positions, a determination is made as to whether precisely one of said first and second signals corresponds to an intermediate position of the selection lever; that, if precisely one of the signals corresponds to an intermediate position of the selection lever, the other signal is subjected to a plausibility to determine the gear selection; that, if none of the signals corresponds to an intermediate position of the selection lever, said first one and said second one of said signals are subjected to a plausibility; and, wherein said plausibility uses said plausibility rules to determine the gear selection, which are based on the evaluation of one or several secondary signals.
