    摘要: A technique for controlling power for V2X communication is provided. The apparatus includes a reception message analysis process configured to analyze headers of reception messages received from communication apparatuses of roadside apparatuses and surrounding vehicles located around a vehicle, a message loss checking process configured to check whether or not loss of the reception messages occurs by counting sequential numbers included in the headers of the reception messages, a density analysis process configured to analyze a density for each of communication apparatuses located in a communication radius of preset transmission power from the vehicle when the message loss checking process determines that the loss of the reception messages occurs, and a transmission power determination process configured to determine transmission power for V2X communication by deducting the preset transmission power in units of reference power according to the density when the density around the vehicle exceeds a reference value.

    摘要: An apparatus including a processor configured to: detect a position of a vehicle and a plurality of positions of fixed objects located around the vehicle based on map coordinates; detect objects based on information measured using a distance measurement sensor disposed in the vehicle; detect a moving object among the detected objects; estimate a plurality of positions of the vehicle and the moving object after a fixed period of time based on a position, a speed, and a movement direction of the moving object; and calculate a degree of proximity risk for the moving object with respect to the vehicle based on a distance and a speed between the vehicle and the moving object.
