Abstract: A first image is generated by imaging a first three-dimensional virtual space including a predetermined object by a first virtual camera. In addition, a map object formed by a three-dimensional model corresponding to the first three-dimensional virtual space is generated, and an indicator object indicating the position of a predetermined object is placed on the map object. Then, a second image is generated by imaging the map object by a second virtual camera. At this time, the second image is generated such that, regarding the indicator object placed on the map object, the display manners of a part hidden by the map object and a part not hidden by the map object as seen from the second virtual camera are different from each other.

Abstract: An on-board update device includes: an update information acquisition unit which acquires data from a device outside a vehicle. A prohibition processing unit prohibits communication between each of the communication devices to be updated and any other communication device. An update information transmission unit transmits the data acquired by the update information acquisition unit, via one or more in-vehicle communication units to the corresponding communication devices to be updated, after the prohibition processing unit has prohibited communication; a completion decision unit decides whether each of the communication devices to be updated has completed an update of the program or data; and a prohibition cancelling unit cancels the prohibition of communication between each of the communication devices to be updated and any other communication device, if the completion decision unit decides that all of the communication devices to be updated have completed their updates.

Abstract: A communication device stores a first secret key and a first public key, and the on-vehicle authentication device stores a second secret key, a second public key and a signature verification key. The on-vehicle authentication device acquires the first public key, verifies the authenticity of the electronic signature using a signature verification key, encrypts the second public key using the authentic first public key and transmits the encrypted second public key. The communication device receives the encrypted second public key, decrypts the encrypted second public key using the first secret key, encrypts the first public key using the decrypted second public key. The on-vehicle authentication device receives the encrypted first public key, decrypts the encrypted first public key using the second secret key, and authenticates that the communication device is an authentic device when the decrypted first public key has been determined to be authentic.

Abstract: In a relay device, a transmitting/receiving unit of an ECU relay receives data. A first counter value is incremented if an amount of data received by the transmitting/receiving unit per unit time exceeds a first threshold. A second counter value is incremented if the amount of data received by the transmitting/receiving unit per unit time exceeds a second threshold. The second threshold is greater than the first threshold. A control unit of a bus relay repeatedly monitors the first counter value. If the first counter value is incremented, the control unit shortens a cycle with which the second counter value is monitored.
