Abstract
Examples of techniques for classifying roughness of a road are disclosed. In one example implementation, a method includes performing a first temporal analysis based at least in part on a speed of each of a plurality of wheels of a vehicle. The method further includes performing a second temporal analysis based at least in part on a combined wheel speed of the plurality of wheels. The method further includes performing a frequency analysis based at least in part on the speed of each of the plurality of wheels of the vehicle. The method further includes classifying the roughness of the road based at least in part on the first temporal analysis, the second temporal analysis, and the frequency analysis.
Claims20
A computer-implemented method for classifying roughness of a road, the method comprising:
- performing, by a processing device, a first temporal analysis based at least in part on a speed of each of a plurality of wheels of a vehicle;
- performing, by the processing device, a second temporal analysis based at least in part on a combined wheel speed of the plurality of wheels;
- performing, by the processing device, a frequency analysis based at least in part on the speed of each of the plurality of wheels of the vehicle;
- and
- classifying, by the processing device, the roughness of the road based at least in part on the first temporal analysis, the second temporal analysis, and the frequency analysis.
A system for classifying roughness of a road, the system comprising:
- a memory comprising computer readable instructions;
- and
- a processing device for executing the computer readable instructions for performing a method, the method comprising:
- performing, by the processing device, a first temporal analysis based at least in part on a speed of each of a plurality of wheels of a vehicle;
- performing, by the processing device, a second temporal analysis based at least in part on a combined wheel speed of the plurality of wheels;
- performing, by the processing device, a frequency analysis based at least in part on the speed of each of the plurality of wheels of the vehicle;
- and
- classifying, by the processing device, the roughness of the road based at least in part on the first temporal analysis, the second temporal analysis, and the frequency analysis.
A computer program product for classifying roughness of a road, the computer program product comprising:
- a computer readable storage medium having program instructions embodied therewith, wherein the computer readable storage medium is not a transitory signal per se, the program instructions executable by a processing device to cause the processing device to perform a method comprising:
- performing, by the processing device, a first temporal analysis based at least in part on a speed of each of a plurality of wheels of a vehicle;
- performing, by the processing device, a second temporal analysis based at least in part on a combined wheel speed of the plurality of wheels;
- performing, by the processing device, a frequency analysis based at least in part on the speed of each of the plurality of wheels of the vehicle;
- and
- classifying, by the processing device, the roughness of the road based at least in part on the first temporal analysis, the second temporal analysis, and the frequency analysis.
