Method for inspecting road surface condition, road surface condition inspection device, and road surface condition inspection system

A road surface condition inspection device that performs inspection of a road surface condition, comprising:

• one or a plurality of storage devices that store detailed information on a road surface condition set for each inspection point based on a traveling record of a vehicle, and information on an own position of the vehicle;
• and
• one or a plurality of processors,
• wherein the one or the plurality of processors is configured to:
• when the inspection point is included in a predetermined range in an advancing direction of the vehicle with the own position as a reference, generate an inspection execution plan of the vehicle in the inspection point,
• perform evaluation of a road surface condition in the inspection point, based on a traveling condition of the vehicle that is obtained during the inspection execution plan, and
• update the detailed information on a road surface condition that is set for the inspection point, based on latest information on the road surface condition the evaluation of which is performed.

A road surface condition inspection system that performs inspection of a road surface condition, comprising:

• a vehicle, and a management device communicable with the vehicle,
• wherein the vehicle comprises a road surface condition inspection device including a first processor and a first storage device, and a vehicle side communication device,
• the management device comprises a second processor, a second storage device, and a management side communication device,
• the first storage device includes information on an own position of the vehicle,
• the second storage device includes detailed information on a road surface condition that is set for each inspection point based on a traveling record of the vehicle,
• wherein the first processor is configured to:
• obtain the detailed information on a road surface condition from the management device;
• when the inspection point is included in a predetermined range in an advancing direction of the vehicle with the own position as a reference, generate an inspection execution plan of the vehicle in the inspection point;
• perform evaluation of a road surface condition in the inspection point based on a traveling condition of the vehicle that is obtained during the inspection execution plan;
• and
• transmit latest information on the road surface condition the evaluation of which is performed to the management device, and
• the second processor is configured to:
• update the detailed information on a road surface condition set for the inspection point based on the latest information on the road surface condition.
