Abstract: A control device distributes electric power from a battery to an electric power feed terminal when the remaining level of a battery is equal to or higher than a predetermined value with an ignition off. Therefore, an electronic component can be charged after being connected to the electric power feed terminal, even with the ignition off. When the remaining level of the battery is lower than the predetermined value, the distribution of electric power from the battery to the electric power feed terminal is shut off, so the electric component can be stopped from being charged, even after being connected to the electric power feed terminal. In consequence, even when the electronic component can be charged after being connected to the electric power feed terminal with the ignition off, a battery remaining level that is needed when a vehicle runs next time can be ensured.

Abstract: An onboard camera image application system includes multiple vehicles, an information providing system, and a PC. In the information providing system, a collection server collects image data captured by onboard cameras of the vehicles. An analysis server extracts, from the image data captured around one location, feature information associated with an extraction item for a person or a vehicle around the location. The analysis server also classifies the extracted feature information by classification item. A providing server sends the classified feature information to the PC of a user. The user is able to set a location to be processed, through the PC, and is also able to set the extraction item or the classification item.

Abstract: In an environment prediction system, environment data is acquired in a plurality of vehicles which are moving objects, and measurement position data is recorded. A collection server of a prediction center collects the environment data in association with the measurement position data. A prediction server of the prediction center performs a spatial environment prediction at a future point in time based on the collected environment data. A result of the environment prediction can be distributed by a distribution server of the prediction center. Examples of the environment prediction include a weather prediction and a distribution prediction of an air pollutant.

Abstract: A distribution system includes a collection server, a storage server, and a distribution server. The collection server acquires image data captured by an on-vehicle camera, creates a table in which imaging position information is associated with imaging environment information, and stores the table in the storage server. The distribution server accepts a distribution request in which an imaging position condition and an imaging environment condition are designated. The distribution server searches the image data satisfying the imaging position condition and the imaging environment condition, and performs distribution.

The electronic control unit is configured to: perform an arithmetic operation for an arithmetic operation task, output a result of the arithmetic operation, and receive an arithmetic operation task from the outside of the vehicle by using the communication function when an amount of arithmetic operations performed in the vehicular arithmetic operation processing device is equal to or less than a predetermined first value; and transmit an arithmetic operation task to the outside of the vehicle by using the communication function when the amount of arithmetic operations which are performed in the vehicular arithmetic operation processing device is equal to or greater than a predetermined second value.

Abstract: Provided is a charging controller that controls a process of charging a battery from an external power source. When an outside air temperature is equal to or lower than a predetermined temperature, the charging controller charges the battery from a time earlier than a scheduled time of use of the battery by a predetermined time until the scheduled time of use. Thus, even when the outside air temperature is equal to or lower than the predetermined temperature, the temperature of the battery has been raised by heat generated during the charging by the time of use of the battery.
