  • Patent number: 12045599
    Abstract: A center device includes an update data storage unit in which new data and new difference data for updating to the new data from old data are stored for, among electronic control units mounted on a vehicle, a target device targeted for data update. The center device generates, using the new data, a first verification value for verifying integrity in the vehicle, and generates, using the new difference data, a second verification value for verifying integrity of the new difference data in the vehicle. The center device generates a package including the new difference data, the first verification values and the second verification values for a plurality of the target devices. The center device generates, using the distribution package, a third verification value for verifying integrity of the distribution package in the vehicle, and transmits the distribution package along with the third verification value to the in-vehicle device.

  • Patent number: 9213104
    Abstract: In a positioning system, an arithmetic processor analyzes positioning data acquired by a receiving terminal and determines a positioning target location. Upon reception of positioning data, the arithmetic processor accumulates the positioning data on analysis data stored in a storage section prior to the reception, stores an accumulated data as new analysis data, and transmits an analysis result to the receiving terminal. The receiving terminal transmits positioning data, acquired for a predetermined time, to the arithmetic processor and continues to acquire positioning data. Upon reception of the analysis result, the receiving terminal determines whether the analysis result is good or poor. When the analysis result is poor and the positioning data is stored for the predetermined time from a last transmission of the positioning data, the receiving terminal transmits the positioning data to the arithmetic processor and continues to acquire positioning data.
