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.

Abstract: Disclosed herein is an electric brake system including a brake including a cylinder and a piston which is provided in the cylinder to move forward or backward and is moved by hydraulic pressure so that a brake pad presses a brake disc, an electric stability control (ESC) actuator configured to generate and supply hydraulic pressure to the cylinder to brake a wheel of a vehicle, an electric parking brake (EPB) actuator configured to move the piston by a motor, and a controller configured to control the EPB actuator and the ESC actuator, wherein the controller estimates a flux in the cylinder and estimates pressure in the cylinder based on whether an EPB is applied through driving of the EPB actuator and the estimated flux in the cylinder.
