Abstract
A system includes a computer including a processor and a memory, the memory storing instructions executable by the computer to determine a recursive standard deviation and a recursive mean offset of a plurality of steering component angles and to identify a wheel misalignment fault upon determining that the recursive standard deviation is below a deviation threshold and the recursive mean offset is above an offset threshold.
Claims20
A system, comprising a computer including a processor and a memory, the memory storing instructions executable by the computer to:
- determine a recursive standard deviation and a recursive mean offset of a plurality of steering component angles;
- and
- identify a wheel misalignment fault upon determining that the recursive standard deviation is below a deviation threshold and the recursive mean offset is above an offset threshold.
A method, comprising:
- determining a recursive standard deviation and a recursive mean offset of a plurality of steering component angles;
- and
- identifying a wheel misalignment fault upon determining that the recursive standard deviation is below a deviation threshold and the recursive mean offset is above an offset threshold.
A system, comprising:
- a steering component movable to a steering component angle;
- means for determining a recursive standard deviation and a recursive mean offset of a plurality of steering component angles of the steering component;
- and
- means for identifying a wheel misalignment fault upon determining that the recursive standard deviation is below a deviation threshold and the recursive mean offset is above an offset threshold.
