Redundant position sensing system for a vehicle

A redundant position sensing system for a vehicle, 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;
• and
• first and second sensor modules that include first and second sensor resistances, respectively, wherein a value of one of said first or second sensor resistances increases and a value of the other of said first or second resistances decreases when said device moves from said minimum position to said maximum position;
• wherein a ratio of a maximum value of said first sensor resistance to a maximum value of said second sensor resistance is less than or equal to 0.5.

A method for operating a redundant position sensing system, comprising:

• connecting first and second sensor modules to a device having a position between minimum and maximum positions, wherein said first and second sensor modules include first and second sensor resistances, respectively;
• increasing a value of one of said first or second sensor resistances when said device moves from said minimum position to said maximum position;
• and
• decreasing a value of the other of said first or second sensor resistances when said device moves from said minimum position to said maximum position,
• wherein a maximum value of said first sensor resistance ranges between a first maximum value and a second maximum value that is greater than said first maximum value due to a first manufacturing tolerance, wherein a maximum value of said second sensor resistance ranges between a third maximum value and a fourth maximum value that is greater than said third maximum value due to a second manufacturing tolerance, and wherein said second maximum value is less than said third maximum value.
