Voice actuated two speed axle
First Claim
1. An apparatus for controlling the gear ratio of an engine-driven vehicle, comprising:
- transmission means having a shifting means for shifting said transmission between a first gear ratio and a second higher gear ratio;
a voice recognizing means for recognizing vocal commands and delivering an upshift command signal in response to an upshift vocal command and a downshift command signal in response to a downshift vocal command; and
an actuation means being operatively connected to actuate said shifting means, said actuation means being responsive to said upshift command signal to operate said shifting means to shift said transmission means from said first gear ratio to said second gear ratio and responsive to said downshift command signal to operate said shifting means to shift said transmission from said second gear ratio to said first gear ratio.

Abstract
A vehicle two speed axle system can be voice-actuated by the vehicle operator. The two speed axle system includes a hydraulically actuated two speed axle unit having a solenoid-actuated control valve. A microphone is utilized to receive spoken commands from the operator which are recognized by a voice recognition and synthesis unit for controlling the system. A speaker is also provided for generating spoken messages representing conditions recognized by the system. The system includes a unique training program which is utilized initially to store voice template signals corresponding to the selected vocal instructions required to operate the system. The training program utilizes the voice synthesizer for prompting the operator through the training program.
