Apparatus and method for controlling a vehicle

An apparatus for controlling a host vehicle, the apparatus comprising:

• a communication device configured to receive first driving information of a front vehicle;
• at least one sensor configured to obtain second driving information of the host vehicle;
• and
• a processor configured to:
• generate real behavior information of the host vehicle based on the second driving information;
• determine a behavior of the front vehicle based on at least one of the first driving information, the second driving information, or any combination thereof;
• calculate a time point at which the host vehicle performs the behavior of the front vehicle;
• generate predicted behavior information of the host vehicle including the time point and the behavior of the front vehicle based on at least one of the first driving information, the second driving information, or any combination of the first driving information and the second driving information;
• determine a manner of outputting a sound based on the real behavior information or the predicted behavior information;
• output the sound through an output device based on the determined manner of outputting the sound;
• and
• determine a state of an occupant based on input information, wherein the input information is input through an input device by the occupant and includes feedback of a motion sickness extent experienced by the occupant.
