VEHICLE-MOUNTED DEVICE AND CONGESTION CONTROL METHOD

摘要

A vehicle-mounted device includes a measurement unit that detects the radio signal to measure a congestion level, a reception unit that receives, from each of the predetermined vehicle-mounted devices, the value of a predetermined parameter, in which a degree of contribution to congestion increases as the value of the parameter increases, from among parameters relating to the communication of the predetermined vehicle-mounted device, and a control unit that sets, when the congestion level measured by the measurement unit is outside a set predetermined range, the value of the predetermined parameter of its own device so that the congestion level is within the predetermined range in consideration of the magnitude relationship between the congestion level and a value within the predetermined range and a magnitude relationship between the value of the predetermined parameter received by the reception unit and the value of the predetermined parameter of its own device.

主权项

1. A vehicle-mounted device, which communicates with a predetermined vehicle-mounted device mounted on each of a plurality of vehicles by a radio signal, comprising:
a measurement unit that detects the radio signal to measure a congestion level; a reception unit that receives, from each of the predetermined vehicle-mounted devices, a value of a predetermined parameter, in which a degree of contribution to congestion increases as the value of the parameter increases, from among parameters relating to the communication of the predetermined vehicle-mounted device; and a control unit that sets, when the congestion level measured by the measurement unit is outside a set predetermined range, the value of the predetermined parameter of its own device so that the congestion level is within the predetermined range in consideration of a magnitude relationship between the congestion level and a value within the predetermined range and a magnitude relationship between the value of the predetermined parameter received by the reception unit and the value of the predetermined parameter of its own device.
