Road condition monitoring system

A road condition monitoring system for a vehicle, the vehicle being supported by at least one tire mounted on a wheel and including a central communication system, the system comprising:

• a processor configured to communicate with the central communication system;
• an identifier stored on the processor and executable on the processor, wherein the identifier causes the processor to at least:
• receive vehicle condition data from the central communication system;
• and
• identify a free rolling instance of the at least one tire, wherein the free rolling instance is a condition experienced when the vehicle travels at a constant speed on a straight road as indicated by the vehicle condition data;
• a slip estimator stored on the processor and executable on the processor, wherein the slip estimator causes the processor to at least:
• receive speed data from the central communication system;
• and
• determine slip characteristics of the at least one tire only during the free rolling instance;
• a classifier stored on the processor and executable on the processor, wherein the classifier causes the processor to at least:
• receive the slip characteristics of the at least one tire only during the free rolling instance;
• and
• identify a road surface condition from the slip characteristics only during the free rolling instance;
• and
• a vehicle control system in electronic communication with the central communication system, the vehicle control system receiving the identified road surface condition for actuation of the vehicle control system in response to the identified road surface condition.
