First Claim
1. A vehicle image data transmission device that transmits image data obtained when driving a vehicle by capturing an image of a vehicle exterior to a management center that manages travel information of a plurality of vehicles, the vehicle image data transmission device comprising:
- an on-vehicle communication device configured to communicate with the management center through a vehicle external network for mobile communication;
a camera that obtains the image data of the vehicle exterior;
a processor configured to calculate a travel easiness score that indicates easiness for the vehicle to travel, which reflects a number of other vehicles and a number of pedestrians based on the image data;
a database that records image data obtained from the camera; and
a communication controller configured to transmit image data recorded in the database to the on-vehicle communication device through a vehicle internal network mounted in the vehicle under a condition in which the vehicle internal network has a communication load that is less than a first predetermined value, whereinthe on-vehicle communication device includes a memory that stores image data received from the communication controller,the on-vehicle communication device is configured to determine that a communication load of the vehicle external network is less than a second predetermined value when the calculated travel easiness score is greater than or equal to a predetermined score and that the communication load of the vehicle external network is greater than or equal to the second predetermined value when the calculated travel easiness score is less than the predetermined score, andthe on-vehicle communication device is configured to transmit image data stored in the memory to the management center under a condition in which the vehicle external network has a communication load that is less than the second predetermined value.

Abstract
A vehicle image data transmission device that transmits image data obtained by capturing an image of a vehicle exterior to a management center managing travel information of vehicles includes an on-vehicle communication device and a communication controller. The communication controller is configured to transmit image data of the vehicle exterior recorded in a record device to the on-vehicle communication device through the internal network when a communication load of the internal network is less than a first predetermined value. The on-vehicle communication device includes a memory storing image data received from the communication controller and is configured to transmit image data stored in the memory to the management center through a vehicle external network when a communication load of the external network is less than a second predetermined value.
