摘要
A road classification system und method is disclosed. The system comprises at least one tire (12) supporting a vehicle (10); a tire-mounted sensor (24) operable to measure a tire inflation pressure; a tire-mounted identification tag operable to identify the one tire by an identification code; a tire construction database operable for identifying a tire construction type for the one tire from the identification code; a vehicle-mounted axle vertical acceleration sensor operable to measure an axle vertical acceleration of the vehicle; and a road surface classification model for concluding a road surface condition based on measured changes in the measured axle vertical acceleration of the vehicle and the measured tire inflation pressure and the identified tire construction type.
