METHOD AND SYSTEM FOR DETERMINING A ROAD CONDITION
First Claim
1. A method for determining a condition of a road traversed by at least one vehicle, the method comprisingdetermining at least one calibration parameter of a part of the vehicle,continuously sensing a vertical acceleration of the vehicle,calculating a road condition value based on the vertical acceleration and on the calibration parameter,continuously monitoring whether the road condition value exceeds a predefined schedule, triggering a road maintenance event if the schedule is exceeded,in the event of a triggered road maintenance event, determining or deriving a vehicle position at the time of the road maintenance event, andproviding event data to at least one receiver, the event data comprising information about the vehicle position and at least one road condition value.

Abstract
The invention pertains to a road condition determining system and a method for determining a condition of a road traversed by at least one vehicle. The road condition determining system comprises a vehicle position determination means for determining a position of the vehicle, a calibration parameter detection unit adapted to determine at least one calibration parameter of a part of the vehicle, a vertical acceleration sensor adapted to continuously sense a vertical acceleration of the vehicle, a calculation unit adapted to calculate a road condition value based on the vertical acceleration and on the calibration parameter, and to continuously monitor whether the road condition value exceeds a predefined schedule, and a data transmission unit adapted to provide maintenance data to at least one receiver, the maintenance data comprising at least an information about the vehicle position.
