ROAD SURFACE EVALUATION APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240310168 titled 'ROAD SURFACE EVALUATION APPARATUS
The road surface evaluation apparatus described in the patent application includes a microprocessor that calculates the roughness value of a road surface for a predetermined period based on driving information from multiple vehicles during that time, and then outputs roughness information including the calculated value.
- The microprocessor also estimates whether the change rate of the roughness value for a second predetermined period exceeds a predetermined threshold compared to the roughness value for a first predetermined period.
- If the estimated change rate exceeds the threshold, the microprocessor acquires more driving information to calculate the roughness value for the second period than if the change rate is below the threshold.
