Definitions

  • an object of the present invention is to provide a technology that ensures communication of high-priority applications even when the communication environment deteriorates without increasing equipment.
  • the present invention it is possible to reduce the number of lines installed for each application, and to ensure communication of high-priority applications even when the communication environment deteriorates.
  • FIG. 2 is a diagram showing an example of the configuration and information flow within the on-vehicle wireless control unit 8 according to the first embodiment.
  • the on-vehicle wireless control section 8 includes at least an application input section 10, an application information control section 11, a communication environment monitoring section 12, and a packet control section 13.
  • the packet control unit 13 controls the transmission of application packets and outputs transmission packets based on the application priority output from the application information control unit 11 and the communication environment information output from the communication environment monitoring unit 12.
  • the packet control unit 13 determines whether or not an application packet can be transmitted based on the application priority and the communication environment information, and upon receiving a situation in which the communication environment has deteriorated from the communication environment information, the packet control unit 13 changes the application priority. Outputs only application packets with a high value as transmission packets.
  • this reference bit indicates normality of the on-board equipment
  • the priority is set to "low” in consideration of the capacity of the video data.
  • this reference bit indicates an abnormality in the on-board equipment
  • the priority is set to "high”. That is, depending on the application related to the on-board device video monitoring 4, the normality or abnormality of the on-board device can be reflected in the reference bits in real time to set the application priority.
