Abstract
Abstract A control system for a motor vehicle of the type including an automatic transmission having a plurality of shift positions and an ignition switch. The system includes a push-button module adapted to be positioned in the passenger compartment of the motor vehicle proximate the vehicle operator and including a plurality of push buttons corresponding respectively to the transmission shift position. Electrical logic means are provided to move the transmission to the shift position corresponding to the shift position selected by depression of the specific push button and an enunciator lamp is associated with each push button. The lamp associated with the push button corresponding to the instantaneous position of the transmission is illustrated to provide a continuous indication of the present position of the transmission and all of the lamps associated with the various push-buttons are illuminated for a predetermined period of time following initial movement of the ignition switch to an activated position to provide a system check to ensure that the lamp display system is working properly. The instantaneous position of the transmission is also displayed in symbol form in a window in the instrument panel immediately forwardly of the operator.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
197 words
A control system for a motor vehicle of the type having a transmission having a plurality of shift positions, a gear selector assembly defining a plurality of select positions corresponding respectively to the transmission shift positions, means operative to generate an electric signal in response to selection of a gear assembly select position, means operative in response to receipt of an electrical signal to shift the transmission to a shift position corresponding to the selected gear assembly position generating the received electrical signal, and an ignition switch, said control system comprising: enunciator means respectively associated with each gear selector assembly select position and operative when individually activated to distinguish the associated select position from the other select positions; means operative to activate the enunciator means associated with the gear selector assembly select position corresponding to the instantaneous shift position of the transmission; and means operative in response to movement of said ignition switch to an activated position to activate all of said enunciator means and to thereafter deactivate all of said enunciator means with the exception of the enunciator means associated with the gear selector assembly select position corresponding to the instantaneous shift position of the transmission.
Claim 2
Dependent Claim
197 words
A control system for a motor vehicle of the type having a transmission having a plurality of shift positions, a gear selector assembly defining a plurality of select positions corresponding respectively to the transmission shift positions, means operative to generate an electric signal in response to selection of a gear assembly select position, means operative in response to receipt of an electrical signal to shift the transmission to a shift position corresponding to the selected gear assembly position generating the received electrical signal, and an ignition switch, said control system comprising: enunciator means respectively associated with each gear selector assembly select position and operative when individually activated to distinguish the associated select position from the other select positions; means operative to activate the enunciator means associated with the gear selector assembly select position corresponding to the instantaneous shift position of the transmission; and means operative in response to movement of said ignition switch to an activated position to activate all of said enunciator means and to thereafter deactivate all of said enunciator means with the exception of the enunciator means associated with the gear selector assembly select position corresponding to the instantaneous shift position of the transmission.
Claim 3
Dependent Claim
