Abstract
Methods and apparatus to identify ride height sensor discrepancies are disclosed. An example apparatus disclosed herein includes machine readable instructions and programmable circuitry to at least one of instantiate or execute the machine readable instructions to compare a first sensor output of a first ride height sensor of a vehicle to a second sensor output of a second ride height sensor of the vehicle, increment a discrepancy counter based on the comparison of the first sensor output and the second sensor output, and generate an indication to service at least one of the first ride height sensor or the second ride height sensor after the discrepancy counter satisfies a threshold.
Claims17
An apparatus comprising:
- machine readable instructions;
- and
- programmable circuitry to at least one of instantiate or execute the machine readable instructions to:
- access a first sensor output, the first sensor output generated at a first time, the first sensor output associated with a first ride height sensor of a vehicle, the first ride height sensor is associated with a first wheel of the vehicle;
- access a second sensor output, the second sensor output generated at a second time separated from the first time by a delay, the second sensor output associated with a second ride height sensor of the vehicle, the second ride height sensor is associated with a second wheel of the vehicle, the second wheel is longitudinally aligned with the first wheel;
- compare the first sensor output to the second sensor output;
- increment a discrepancy counter based on the comparison of the first sensor output and the second sensor output;
- and
- generate an indication to service at least one of the first ride height sensor or the second ride height sensor after the discrepancy counter satisfies a threshold.
A non-transitory machine readable storage medium comprising instructions to cause programmable circuitry to at least:
- access a first sensor output, the first sensor output generated at a first time, the first sensor output associated with a first ride height sensor of a vehicle, the first ride height sensor is associated with a first wheel of the vehicle;
- access a second sensor output, the second sensor output generated at a second time separated from the first time by a delay, the second sensor output associated with a second ride height sensor of the vehicle, the second ride height sensor is associated with a second wheel of the vehicle, the second wheel is longitudinally aligned with the first wheel;
- compare the first sensor output to the second sensor output;
- increment a discrepancy counter based on the comparison of the first sensor output and the second sensor output;
- and
- generate an indication to service at least one of the first ride height sensor or the second ride height sensor after the discrepancy counter satisfies a threshold.
