  • Publication number: 20200241771
    Abstract: A vehicle information communication system includes a vehicle device and a center device. The center device includes a storage unit, a center computer, and a center-device communication unit. The storage unit stores memory structure information for each of the ECUs. The memory structure information indicates whether a corresponding memory has a memory structure that supports Read While Write (RWW) operation defined as having a plurality of physically independent memory regions. The center computer is programmed to generate specification data including the memory structure information for each of the at least one target ECUs. The vehicle device includes a vehicle computer. The vehicle computer is programmed to perform the program data rewrites of the at least one target ECU according to the memory structure information included in the specification data.

  • Publication number: 20200183676
    Abstract: A vehicle information communication system includes a center apparatus and a vehicle apparatus that includes a group of electronic control units (ECUs) and that sends vehicle configuration information including configuration information on the group of ECUs mounted in the vehicle to the center apparatus via wireless communications. The center apparatus performs a first determination of whether the vehicle configuration information received from the vehicle apparatus matches approved-configuration information registered in an approved-configuration database, and performs a second determination of whether software update data for at least one ECU of the group of ECUs mounted in the vehicle exists in an update database. When both the first and second determinations are true, the center apparatus sends the software update data for at least one ECU of the group of ECUs mounted in the vehicle to the vehicle apparatus via the wireless communications.

  • Patent number: 6482033
    Abstract: A coaxial cable connector plug includes a connector body having the end of a coaxial cable fixed therein and a housing having an insertion hole to accommodate the connector body. The housing has a cantilever-like engagement nail extending in the insertion hole, thereby permitting the connector body to be caught by a frusto-conical transition in the insertion hole. The housing has a catch hole made in the vicinity of the cable-inlet of the housing. When a wedge-like retainer is inserted into the remaining space between the connector body and the floor of the housing, the wedge-like retainer is caught by the hook end, thus filling the remaining space and making the coaxial cable tightly retained in the housing. With this arrangement, the connector body can be removed from the housing so as to be reused.
