Abstract: A wireless communication device used in a vehicle is provided, includes a communicator that performs wireless communication with a service provider terminal, a vehicle condition acquirer that acquires a condition of the vehicle, a correspondence storage that stores a correspondence of what type of service is available under what condition of the vehicle, and an availability determiner that determines whether the service provided by the service provider terminal is available under the condition of the vehicle acquired by the vehicle condition acquirer, based on service type information included received by the communicator, the condition of the vehicle acquired by the vehicle condition acquirer, and the correspondence stored in the correspondence storage.

Abstract: Vehicle exterior images are captured sequentially by an imaging portion of an imaging-equipped mobile terminal used in a first vehicle and stored temporarily in an image temporary-storage portion in the first vehicle. The first vehicle receives vehicle information from a second vehicle different from the first vehicle, through inter-vehicle communication. When it is determined that a sudden deceleration arises in the second vehicle based on the vehicle information received by the first vehicle, the vehicle exterior images stored in the image temporary-storage portion are read and saved in a memory.

The in-vehicle unit in the subject vehicle includes a criterion value setting section and a different-unit anomaly detection section. The criterion value setting section receives a different-unit installation state index via the inter-vehicle communicator and sets successively a criterion value of an installation state index from the received different-unit installation state index specified based on an output value from a sensor instrument that successively outputs an output value corresponding to an installation state of the in-vehicle unit on each nearby vehicle. The different-unit anomaly detection section detects an abnormal installation state of the in-vehicle unit on a target nearby vehicle by comparing the criterion value with the different-unit installation state index received from the target nearby vehicle.
