  • Publication number: 20250119473
    Abstract: The relay device includes multiple communication ports to which the in-vehicle ECU can be connected, a CPU, and a port storage area for each communication port. CPU can perform a reprogramming process for multiple in-vehicle ECUs in parallel. CPU performs: receiving a list of update data that has not been sent to the in-vehicle ECU and a data volume for each of the update data that has not been sent to the in-vehicle ECU; acquiring a rate of increase in free space for each port storage area during the reprogramming process; determining, as the priority update data, update data to be received out of the update data listed in the list based on the data volume for each of the update data and the rate of increase in free space for each of the port storage areas; and sending, to the providing device, a signal requesting the priority update data.

  • Patent number: 12137391
    Abstract: A terminal device configured to communicate with a management server through a network is provided in association with a vehicle. The terminal device is configured to acquire the speed information representing the moving speed of the vehicle and the position information representing the position of the terminal device, to determine whether the position information represents the position located in a specific area which is determined in advance, and to download content from the management server when the position information indicates the position included in the specific area. Upon receiving the content information representing a capacity of the content downloadable from the management server, the terminal device may download the content corresponding to the content information according to a predetermined condition relating to a relationship between the speed information and the content information.

  • Publication number: 20240264821
    Abstract: A CPU receives update data, stores the received update data in a first memory, transmit the update data via an internal communication line and a specific communication line while prohibiting data transmission from an internal device via the internal communication line and permitting data transmission from a specific device via the specific communication line, erase from the first memory the update data that has been successfully transmitted via the internal communication line and the specific communication line, and when a data volume stored in the first memory becomes equal to or larger than a predetermined set volume, erase from the first memory the update data for the internal device even if this update data is the update data that has not yet been transmitted via the specific communication line.

  • Patent number: 11652745
    Abstract: An on-board network system includes at least one processor. Plural relay devices that temporarily retain received data and relay the retained data in descending order of relay priority levels include a first relay device. For each set of data retained at the first relay device, the processor measures a retention duration for which the data is retained without being relayed. Data whose measured retention duration exceeds a predetermined threshold is congested data. A second relay device is a different relay device from the first relay device among the plurality of relay devices, and is capable of relaying the congested data. The processor requests the second relay device to raise the relay priority level of the congested data.

  • Patent number: 11637782
    Abstract: At this time, a communication line load transmission interval deciding unit selects a transmission interval from the load of the bus. An instrument load transmission interval deciding unit selects a transmission interval from the processing loads of at least one of the vehicle on-board instrument and the gateway. A delivery control unit compares the transmission interval selected by the communication line load transmission interval deciding unit with the transmission interval selected by the instrument load transmission interval deciding unit, and performs control so that the divided updating data is delivered at transmission intervals which are equal to or greater than the longer of these transmission intervals.
