VOICE ACTUATED TWO SPEED AXLE

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 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.
