According to one embodiment, a vehicle control device, which is a control device of a vehicle using a motor as a driving source, comprises a control unit which performs regenerative braking based on the motor when a driver has a will to drive, determines a road frictional coefficient according to deceleration of the vehicle when wheel slip occurs during the regenerative braking, determines ED control entry sensitivity based on the determined road frictional coefficient, determines whether the vehicle control device enters EDC control by applying the determined EDC control entry sensitivity, and stops the regenerative braking and increases torque of the motor during EDC control entry to perform the EDC control reducing the generated wheel slip.
일실시예에 따른 차량 제어 장치는 모터를 구동원으로 하는 차량의 제어 장치에 있어서, 운전자의 제동의지가 있으면, 모터에 기반한 회생 제동을 수행하고, 회생 제동 중 휠 슬립이 발생하면, 차량 감속도에 따라 노면마찰계수를 판단하고, 판단된 노면마찰계수를 근거로 EDC 제어 진입 민감도를 결정하고, 결정된 EDC 제어 진입 민감도를 적용하여 EDC 제어 진입 여부를 판단하고, EDC 제어 진입이면, 상기 회생 제동을 정지시킴과 함께 모터의 토크를 증가시켜 발생된 휠 슬립을 저감시키는 EDC 제어를 수행하는 제어부를 포함한다.
