Abstract
A set of inputs each selectively provides a discrete signal, whereby the sensor inputs together provide a plurality of discrete signals. A memory includes instructions executable by a processor for receiving the discrete signals, identifying a bit pattern from the discrete signals, and determining a position of a physical member according to the bit pattern and an error condition detected from the discrete signals.
Claims23
A method, comprising:
- detecting a plurality of discrete signals, each of the discrete signals being received from a respective one of a plurality of inputs;
- identifying a detected bit pattern based on the discrete signals;
- detecting selectively an error condition, and identifying the error condition as one of at least one of a short to battery condition, a short to ground condition, and a failure of a make after break feature, according to the bit pattern;
- and
- determining an expected position of a physical member according to the bit pattern;
- wherein the make after break feature fails if one of the inputs that was in a high asserted state fails to break to a low or non-asserted state when the physical member moves from a first detent position to a second detent position.
A system, comprising:
- a set of sensors providing inputs that each selectively provide a discrete signal, whereby the sensor inputs together provide a plurality of discrete signals;
- a processor;
- and
- a memory including instructions executable by the processor for:
- receiving the discrete signals,
- determining a bit pattern from the discrete signals,
- detecting selectively an error condition, and identifying the error condition as one of at least one of a short to battery condition, a short to ground condition, and a failure of a make after break feature, according to the bit pattern,
- and identifying a position of a physical member according to the bit pattern;
- wherein the make after break feature fails if one of the inputs that was in a high asserted state fails to break to a low or non-asserted state when the physical member moves from a first detent position to a second detent position.
A computer-readable medium tangibly embodying instructions executable by a processor, the instructions comprising instructions for:
- detecting a plurality of discrete signals, each of the discrete signals being received from a respective one of a plurality of inputs;
- identifying a detected bit pattern based on the discrete signals;
- detecting selectively an error condition, and identifying the error condition as one of at least one of a short to battery condition, a short to ground condition, and a failure of a make after break feature, according to the bit pattern;
- and
- determining an expected position of a physical member according to the bit pattern;
- wherein the make after break feature fails if one of the inputs that was in a high asserted state fails to break to a low or non-asserted state when the physical member moves from a first detent position to a second detent position.
