    Abstract: Disclosed herein are an apparatus and method for adaptive autonomous driving control. The apparatus includes memory in which at least one program is recorded and a processor for executing the program. The program may perform control of a target vehicle by converting a theoretical control value based on a vehicle control algorithm into a hardware-dependent control value, which is dependent on the platform or hardware of the target vehicle, and may modify at least one parameter or a conversion equation for conversion of the hardware-dependent control value such that an error is minimized based on the difference between a response value according to the control of the target vehicle and a control value.

    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.
