  • Publication number: 20210119831
    Abstract: An in-vehicle network system deployed in a vehicle includes a plurality of first nodes configured to perform an operation relevant to a first function in the vehicle, a second node configured to perform an operation relevant to a second function different from the first function in the vehicle; and a relay device configured to relay communication between the first nodes and the second node. The relay device is configured to start relay of communication between the first nodes earlier than the relay of communication between the first node and the second node at a time of startup.

  • Patent number: 10887128
    Abstract: An in-vehicle network system includes a plurality of relay devices that is connected to control devices of a vehicle, and communicates with each other and is configured such that each of a plurality of request devices that transmits a response request to the control device is connected to any one of the relay devices, a storage unit that stores a priority of the request devices, a master setter that sets, as the master, the relay device to which the request device having the highest priority has been connected among the relay devices to which any one of the request devices has been connected, and an arbitrator that performs arbitration to prioritize a response request from the request device having the highest priority when the response requests are transmitted from at least two of the request devices when the relay device in which the arbitrator is included is the master.

  • Patent number: 10668876
    Abstract: An in-vehicle network system includes a plurality of controllers; a plurality of communication lines connected to the controllers, respectively, a relay device connected to the controllers via the communication lines, and a retention determiner configured to determine whether retention of data occurs in the relay device. The relay device is configured to relay data between the communication lines, and configured to preferentially relay data having a priority equal to or higher than a predetermined priority such that the data reaches the controller that is a transmission destination among the controllers within a first predetermined time when the retention determiner determines that the retention occurs.

  • Patent number: 9188708
    Abstract: Provided is a film having a low refractive index, which can be formed under normal temperature and pressure while obtaining a lower refractive index, has excellent adhesion with a solid substrate, and does not lose geometric optical properties, such as the diffusibility or light-harvesting capability attributed to the microstructure. Also disclosed is a method for producing the same. The film having a low refractive index is obtained by causing an electrolyte polymer and microparticles to be alternately adsorbed on the surface of a solid substrate and bringing the resulting microparticle-laminated film into contact with a silicon compound solution in order to bond the solid substrate with microparticles and microparticles with microparticles.
