Disclosed are a vehicle control device and a method thereof. According to an embodiment of the present invention, the vehicle control device, which performs a hill start assist (HSA) control for preventing a vehicle from being pushed at start after stopping at a hill, comprises: a wheel speed sensor for detecting a wheel speed of a wheel; and a BTCS controller for performing a brake traction control system (BTCS) control for controlling a braking pressure of the wheel through a hydraulic modulator when the wheel is slipped. The BTCS controller varies the slope of a pressure increase during the BTCS control in accordance with whether a wheel pressure remains on the wheel due to the HSA control during the BTCS control.
차량 제어 장치 및 방법이 개시된다. 본 발명의 일실시예에 따른 차량 제어 장치는 차량의 언덕 정차 후 출발시 밀림을 방지하는 HSA((Hill Start Assist) 제어를 수행하는 차량 제어 장치에 있어서, 바퀴의 휠 속도를 검출하는 휠 속도 센서와, 바퀴에 슬립 발생시 유압모듈레이터를 통해 바퀴의 제동압력을 제어하는 BTCS(Brake Traction Control System) 제어를 수행하는 BTCS 제어기를 포함하고, BTCS 제어기는 BTCS 제어시 바퀴에 HSA 제어로 인한 휠 압력이 잔존하는지에 따라 BTCS 제어시의 압력 상승 기울기를 가변시킨다.
