摘要：The invention has the object of avoiding congestion while reducing differencesbetween parameters for communication among vehicles. The vehicle-mounted deviceperforming communication by radio signals with predetermined vehicle-mounted devices

respectively equipped in a plurality of vehicles includes: a radio unit detecting radiosignals to measure congestion level; a processor receiving, from each of thepredetermined vehicle-mounted devices, a value of, among parameters relating tocommunication of the predetermined vehicle-mounted devices, a predeterminedparameter for which the degree of contribution to congestion increases with increase inthe value of the predetermined parameter ; and a controller decreasing, when thecongestion level measured by the radio unit exceeds a predetermined threshold value,the value of the predetermined parameter of its own device if the value of the

predetermined parameter of its own device is greater than the average of the values ofthe predetermined parameter received at the processor.
