Wireless Communication Control Device Patent Published

Strategic Insights -

A patent titled "Wireless communication control device, wireless communication device, and wireless communication control method" has been published online on September 30, 2025, by the United States Patent and Trademark Office (USPTO). The patent, issued as U.S. Patent Number 12432643, was filed by Masayuki Hoshino and Yosuke Ogi on February 6, 2023, and is owned by Denso Corporation.

The patent describes a wireless communication control device that controls a wireless communication device mounted on a vehicle to transmit and receive information via wireless communication with an access point of a wireless network. The device includes an identification information acquisition unit, a point identification unit, a communication status acquisition unit, and a prediction unit. The identification information acquisition unit acquires identification information for identifying the access point of a target network existing on the route of the vehicle. The point identification unit identifies an on-route access point that is the access point of the target network on the route of the vehicle by using the identification information acquired by the identification information acquisition unit. The communication status acquisition unit acquires communication status information regarding a communication status in a target communication range that is a communication range to which the vehicle comes close, via wireless communication other than the wireless communication with the access point of the target network. The prediction unit predicts a frequency channel with less interference in the wireless communication in the target communication range by using the communication status information acquired by the communication status acquisition unit.

Key Takeaways:

  • The patent describes a wireless communication control device that controls a wireless communication device mounted on a vehicle to transmit and receive information via wireless communication with an access point of a wireless network.
  • The device includes an identification information acquisition unit, a point identification unit, a communication status acquisition unit, and a prediction unit.
  • The identification information acquisition unit acquires identification information for identifying the access point of a target network existing on the route of the vehicle.
  • The point identification unit identifies an on-route access point that is the access point of the target network on the route of the vehicle by using the identification information acquired by the identification information acquisition unit.
  • The communication status acquisition unit acquires communication status information regarding a communication status in a target communication range that is a communication range to which the vehicle comes close, via wireless communication other than the wireless communication with the access point of the target network.
  • The prediction unit predicts a frequency channel with less interference in the wireless communication in the target communication range by using the communication status information acquired by the communication status acquisition unit.
  • The device is further configured to acquire communication status information when there is information that needs to be transmitted or received by the wireless communication device.
  • The device is further configured to determine a timing when a distance between the on-route access point identified by the point identification unit and the vehicle is equal to or less than a threshold distance longer than the communication range of the on-route access point as a timing when the vehicle comes close to the target communication range.
  • The device is further configured to determine a timing when a time estimated to be a remaining time until the vehicle enters the communication range of the on-route access point identified by the point identification unit becomes equal to or less than a threshold time as a timing when the vehicle comes close to the target communication range.
  • The frequency channel with less interference is a frequency channel that is not in use.
  • The device includes a processor that serves as the point identification unit, the communication status acquisition unit, and the prediction unit.
