  • Patent number: 12050691
    Abstract: A security processing device which manages a device related to operation control of a vehicle includes a non-transitory computer-readable medium configured to store instructions executable by one or more processors. The non-transitory computer readable medium includes a non-secure area in which a mounted program is capable of being changed from an outside and a secure area in which a mounted program is incapable of being changed from the outside. The instructions cause a code of an operation program in the non-secure area to perform the operation control of the vehicle, and a diagnosis program in the secure area to diagnose an abnormality of the code of the operation program. When the abnormality of the operation program in the non-secure area is diagnosed, the instructions cause the diagnosis program in the secure area to determine a type of the abnormality and execute processing on a basis of the determined type.

    Abstract: A display device includes: a display panel including panel terminals; and a wiring substrate including first substrate terminals coupled to the panel terminals. The panel terminals include panel terminals arranged in a first region and panel terminals arranged in second regions sandwiching the first region. The first substrate terminals include first substrate terminals arranged in a third region and first substrate terminals arranged in fourth regions sandwiching the third region. A gap between panel terminals is substantially constant in the first and second regions. A first width of the panel terminals in the first region is different from a second width of the panel terminals in the second regions. A width of the first substrate terminals is substantially constant in the third and fourth regions. A first gap between first substrate terminals in the third region is different from a second gap between first substrate terminals in the fourth regions.

  • Publication number: 20230115760
    Abstract: Provided is an in-vehicle device capable of switching as to whether to make a diagnosis or not when the identification number of the vehicle is not registered in the server. The in-vehicle device 1 includes an OTA center communicating unit 2 (first communication circuit) that establishes wireless communication with an OTA center 300 (server), a memory 1b (first memory) that stores therein diagnosis permission information 4 (first information) indicating diagnosis permitted or diagnosis not permitted, and a CPU 1a (first processor). When the VIN (identification number) of the vehicle 11 having the in-vehicle device 1 onboard is not registered in the OTA center 300 and the diagnosis permission information 4 indicates diagnosis permitted, the CPU 1a makes a diagnosis of the in-vehicle device 1 and stores the result.

  • Patent number: 11374786
    Abstract: The invention realizes a gateway device capable of shortening the time required for routing to a CAN bus of the opposite microcomputer side and reducing the delay of data transfer. If the indexes are the same, a microcomputer 1 and a microcomputer 2 include common routing tables 10 and 20 in which the same contents are defined. The microcomputer 1 sends the index to the microcomputer 2. The microcomputer 2 that has received the index reads the routing rule defined in the common routing table 20 by the received index.

  • Patent number: 11362859
    Abstract: The present invention provides an in-vehicle communication device and an in-vehicle system that can establish communication, in a short time, between applications corresponding to the same communication protocol between in-vehicle processing devices connected to communication buses having different communication protocols. In the present invention, when the first communication controller 33 has received a specific message from the first in-vehicle processing device 102 connected to the first communication bus 101, the in-vehicle communication device 1 transmits a communication protocol switching command from the second communication controller 3 to the second in-vehicle processing device 202 connected to the second communication bus 201 to switch a communication protocol setting of the second communication controller to the same communication protocol setting as that of the first communication bus.
