PWM and variable frequency based position indicators

A vehicle control system, comprising:

• a vehicle device having a position between minimum and maximum positions, wherein said vehicle device is one of an accelerator pedal, a brake pedal, a clutch pedal, or a throttle blade of a vehicle;
• a first position sensor that senses said position of said vehicle device and generates a first position value;
• a second position sensor that senses said position of said vehicle device and generates a second position value;
• a sensor module that communicates with said first and second position sensors and that generates a single signal waveform based on said first and second position values, wherein a frequency of said waveform is varied based on said first position value and a duty cycle of said waveform is varied based on said second position value;
• a conductor having a first end that communicates with said sensor module and a second end;
• and
• a control module that communicates with said second end of said conductor, wherein said sensor module transmits said waveform to said control module on said conductor and said control module decodes said waveform to determine said first and second position values.

A method for transmitting dual position values on a single signal waveform, comprising:

• sensing a position of a device with a first position sensor, wherein said position of said device is between minimum and maximum positions and wherein said first position sensor generates a first position value;
• sensing said position of said device with a second position sensor, wherein said second position sensor generates a second position value;
• generating a single signal waveform based on said first and second position values;
• varying a frequency of said waveform based on said first position value;
• varying a duty cycle of said waveform based on said second position value;
• transmitting said waveform to a control module on a conductor;
• and
• decoding said waveform at said control module to determine said first and second position values.
