Abstract
By a map update system, an in-vehicle device, or a server, it is determined whether a failure is in vehicle control executed by a vehicle controller configured to control behavior of a vehicle using map information stored in a storage mounted on the vehicle. Further, the map update system or the server, it is determined to whether to update the map information.
Claims17
A map update system for determining whether an update of map information that is stored in a storage of a vehicle and used by a vehicle controller configured to control behavior of the vehicle is necessary, the system comprising:
- a failure determination unit configured to determine whether a failure is in vehicle control executed by the vehicle controller;
- and
- an update determination unit configured to determine that the update of the map information is necessary based on determination that a cause of the failure is in the map information.
An in-vehicle device comprising:
- a failure determination unit configured to
- determine whether a failure is in vehicle control executed by a vehicle controller configured to control behavior of a vehicle using map information stored in a storage of the vehicle, and
- transmit failure determination result information indicating a determination result from a vehicle communication unit to a server;
- and
- an inspection unit configured to, when receiving an inspection instruction from the server,
- compare the map information stored in the storage with recognition map information generated based on information detected by a periphery detection sensor mounted on the vehicle to determine, for inspection, whether the map information stored in the storage is correct, and
- transmit an inspection result from the vehicle communication unit to the server.
A server comprising:
- an inspection necessity determination unit configured to receive failure determination result information that is information indicating a determination result of whether a failure is in vehicle control by a vehicle controller configured to control behavior of a vehicle using map information stored in a storage mounted on the vehicle;
- and
- an inspection instruction unit configured to transmit, to at least one in-vehicle device, an inspection instruction for instructing the at least one in-vehicle device to inspect a cause of the failure when the inspection necessity determination unit determines to inspect the cause of the failure,
- wherein
- the vehicle includes a plurality of vehicles, and
- the server further includes an update determination unit configured to, when receiving the failure determination result information from the plurality of vehicles,
- statistically process the failure determination result information from the plurality of vehicles,
- determine whether the cause of the failure is in the map information, and
- determine to update the map information based on determination that the cause of the failure is in the map information.
