Abstract: A channel control method and apparatus for improving the transmission capacity of packet data and communications reliability in V2X vehicle packet communications. In V2X wireless communications, the number and bandwidths of transmission channels are predetermined. The control method monitors signal levels received between transceivers and the frequency of channel usage, and based on the result. of the monitoring, varies at least one of the bandwidth of frequency channels and the number of transmission channels. The control method is adaptive to wireless channels. The bandwidth of a transmission channel is variably assigned to, depending on whether the channel status for signal reception is good or bad. The number of transmission channels is variably assigned to, depending on whether the usage frequency of a reception channel is low or high.

Abstract: Disclosed is a system performing a method for detecting intersection traffic light information including a traffic light detection module including an image sensor for generating first signal data based on traffic light image data in which a traffic light is included, a communication module that receives second signal data for communication with a surrounding object and an external device, an object information collection module that collects dynamic data of the surrounding object, and a signal information inference module that infers third signal data based on the dynamic data. The dynamic data of the surrounding object includes at least one information of whether the surrounding object moves, a moving direction of the surrounding object, and whether the surrounding object accelerates or decelerates. Each of the signal data includes pieces of information about a type of the traffic light and a signal direction of the traffic light.
