The invention provides a vehicle control device for avoiding erroneous determination of backward movement of a vehicle. A vehicle control device for controlling a travel motor coupled to a wheel includes a motor control unit for controlling the travel motor when executing a constant-speed travel mode in which the travel speed of the vehicle is kept constant in an extremely low-speed region. A vehicle speed calculation unit that calculates a sensor actual vehicle speed, which is the traveling speed of the vehicle, on the basis of the rotational angle of the traveling motor; a vehicle speed setting unit that sets a control actual vehicle speed, which is the traveling speed of the vehicle for the constant-speed traveling mode, on the basis of the sensor actual vehicle speed and the brake operation amount; the vehicle speed setting unit sets zero as an actual vehicle speed for control when the brake operation amount exceeds a threshold value and the actual vehicle speed of the sensor is lower than the threshold v
