摘要： A driver assistance device mounted on a vehicle includes a communication unit; an output unit; an input unit configured to detect user input; and a control unit configured to perform driver assistance with use of a point on a map as a destination. The control unit is configured to i) execute a connection process to connect the driver assistance device to a terminal device wirelessly via the communication unit, ii) output identification information on the terminal device as an image or a voice via the output unit after the driver assistance device is wirelessly connected to the terminal device, and iii) execute a setting process to set the point determined by the terminal device as the destination for the driver assistance in a case where the control unit detects specified user input via the input unit after outputting the identification information on the terminal device.

摘要： A communication system includes an external server and an on-board device mounted on a vehicle. The external server is configured to communicate with the on-board device. A communication method used between the on-board device and the external server includes a first communication method and a second communication method with a larger communication load than the first communication method. The on-board device is configured to switch the communication method based on a vehicle state.

摘要： An onboard device transfers an encrypted message encrypted outside a vehicle to one or more vehicle controllers connected to a vehicle network. When the encrypted message is an individual message to one of the vehicle controllers, the onboard device transmits the encrypted message to the one of the vehicle controllers via the vehicle network. When the encrypted message is a common message to the one or more vehicle controllers, the onboard device decrypts the encrypted message using an encryption key owned by the onboard device and then transmits the decrypted message to the one or more vehicle controllers via the vehicle network.

摘要： A forgetting-to-carry prevention assistance method assists, in a terminal device, a user in preventing forgetting to carry a personal item. The forgetting-to-carry prevention assistance method includes acquiring a destination for the user; detecting the personal item that exists around the user; and in a case where the personal item associated with a category of the destination is not detected, notifying information on the personal item that is not detected.

摘要： An information processing device includes a first communication unit configured to communicate with a first terminal device, a second communication unit configured to communicate with a second terminal device, and a controller configured to generate an abnormality detection signal when an abnormality is detected based on vehicle information on a vehicle, and determine a position of a user based on a communication state of the first terminal device and the second terminal device possessed by the user. The controller is configured to cause the first communication unit to transmit the abnormality detection signal to the first terminal device when the controller determines that the position of the user is included in a first region, and cause the second communication unit to transmit the abnormality detection signal to the second terminal device when the controller determines that the position of the user is included in a second region.

摘要： A vehicle-oriented service providing system includes an in-vehicle device and configured to receive commands applied to a control device inside the vehicle, a vehicle information server configured to transmit the commands to the in-vehicle device, and a push information server configured to mediate the transmission of the commands from the vehicle information server to the in-vehicle device. In the commands, a security level prescribed in advance for each of the commands is set. The vehicle information server performs encryption corresponding to the security level on the commands, and requests the push information server for transmission. The in-vehicle device is configured to wait for commands from the push information server. The in-vehicle device is configured to decrypt the received encrypted commands, and solely when encryption corresponding to a security level equal to or higher than the security level set in advance in the commands is performed, execute the commands.

摘要： A communication system includes a plurality of processors coupled with a network, each of the processors having a predefined encryption method for a communication with a server. Each of the processors configured to determine a primary processor of the processors based on at least one of a processability of the processor, network distance to the processor, or cipher strengths, when the processor is not determined as the primary processor, transfer unencrypted communication data through the network to the primary processor, and when the processor is determined as the primary processor, perform an encryption of unencrypted communication data received, and an encrypted communication with the server by the encryption method of the primary processor.

摘要： An on-board communication system includes an on-board communication device and on-board devices. Each of the on-board devices includes a communication device controller configured to control data communication performed between the on-board communication device and a server and a priority setting portion configured to set priority ranks of the on-board devices for controlling the on-board communication device. When each of the on-board devices performs data communication with the server and if any one of the on-board devices is set to a higher priority rank, the on-board device is configured to transmit communication data to the on-board device that is set to a higher priority rank to perform data communication with the server via the on-board device that is set to a higher priority rank and the on-board communication device.
