Vehicle control system for detecting a short-circuit condition between redundant position sensors
First Claim
1. A control system, comprising:
- a device having a position between minimum and maximum positions;
first and second sensor modules that sense said position of said device and that generate first and second position values, respectively; and
a control module that receives said first and second position values and that computes first and second normalized position values that represent a fraction of a range between minimum and maximum values of said first position value and between minimum and maximum values of said second position value, respectively,wherein said control module suspends a control procedure that is based on at least one of said first normalized position value and/or said second normalized position value while a difference between said first and second normalized position values is greater than or equal to a first predetermined value and while at least one of said first normalized position value and/or said second normalized position value is less than or equal to a second predetermined value.

Abstract
A control system includes a device having a position between minimum and maximum positions. First and second sensor modules sense the position of the device and generate first and second position values. A control module receives the position values and computes first and second normalized position values that represent a fraction of a range between minimum and maximum values of the first position value and between minimum and maximum values of the second position value. The control module suspends a control procedure that is based on at least one of the first normalized position value and/or the second normalized position value while a difference between the first and second normalized position values is greater than or equal to a first predetermined value and while at least one of the first normalized position value and/or the second normalized position value is less than or equal to a second predetermined value.

16. A vehicle control system, comprising:
-
an accelerator pedal having a position between minimum and maximum positions; first and second sensor modules that sense said position of said accelerator pedal and that generate first and second position values, respectively; a control module that receives said first and second position values and that computes first and second normalized position values that represent a fraction of a range between minimum and maximum values of said first position value and between minimum and maximum values of said second position value, respectively; and a throttle blade, wherein said control module adjusts a position of said throttle blade based on at least one of said first normalized position value and/or said second normalized position value, wherein said control module foregoes adjusting said position of said throttle blade while a difference between said first and second normalized position values is greater than or equal to 0.05 and while at least one of said first normalized position value and/or said second normalized position value is less than or equal to 0.09.
