Abstract: A vehicle control apparatus and a method for controlling the same are disclosed. The vehicle control apparatus includes an inputter, a determiner, and a controller. The inputter receives an automatic vehicle hold (AVH) switch operation signal from an AVH device, and receives a current vehicle movement value sensed by a sensing device and a current vehicle brake force value of a brake device that generates brake force in response to activation of the AVH device. The determiner determines whether the received AVH switch operation signal transitions from an ON state to an AVH entry state, determines whether vehicle movement occurs on the basis of the received current vehicle movement value during an AVH retention time in the AVH entry state, and determines that the current vehicle brake force value is in an abnormal state when vehicle movement occurs. The controller receives the current vehicle movement value and the current vehicle brake force value, and transmits a command for judgment to the determiner.
