Abstract
The disclosed technology provides solutions for efficiently and accurately identifying degraded suspension components. A method of the disclosed technology can include steps for associating a threshold measurement to a road feature; collecting sensor data from a sensor on an autonomous vehicle, wherein the sensor data includes a plurality of measurements associated with the road feature; identifying, from the sensor data, at least one measurement that is outside of the threshold measurement and indicative of a degraded suspension component of the autonomous vehicle; and identifying a location on the autonomous vehicle of the degraded suspension component based on the sensor data. Systems and machine-readable media are also provided.
Claims20
A computer-implemented method for detecting a degraded suspension component, comprising:
- associating a threshold measurement to a road feature;
- collect sensor data from at least one sensor on an autonomous vehicle, wherein the sensor data includes a plurality of measurements from the at least one sensor, the sensor data associated with the road feature;
- identify, from the sensor data, at least one measurement from the plurality of measurements that is outside of the threshold measurement and indicative of a degraded suspension component of the autonomous vehicle;
- and
- identify a location on the autonomous vehicle of the degraded suspension component based on the sensor data.
A non-transitory computer-readable storage medium comprising at least one instruction for causing a computer or processor to:
- associate a threshold measurement to a road feature;
- collect sensor data from a sensor on an autonomous vehicle, wherein the sensor data includes a plurality of measurements from the at least one sensor, the sensor data associated with the road feature;
- identify, from the sensor data, at least one measurement from the plurality of measurements that is outside of the threshold measurement and indicative of a degraded suspension component of the autonomous vehicle;
- and
- identify a location on the autonomous vehicle of the degraded suspension component based on the sensor data.
A system comprising:
- at least one processor;
- and
- at least one memory storing computer-readable instructions that, when executed by the at least one processor, causes the at least one processor to:
- associate a threshold measurement to a road feature;
- collect sensor data from a sensor on an autonomous vehicle, wherein the sensor data includes a plurality of measurements from the at least one sensor, the sensor data associated with the road feature;
- identify, from the sensor data, at least one measurement from the plurality of measurements that is outside of the threshold measurement and indicative of a degraded suspension component of the autonomous vehicle;
- and
- identify a location on the autonomous vehicle of the degraded suspension component based on the sensor data.
