1. An adaptive cruise control method on an incline comprising:

  • sensing, by a sensing unit, a wheel speed and a longitudinal acceleration during adaptive cruise control;

    calculating, by an electronic control unit, a vehicle acceleration based on the sensed wheel speed;

    estimating, by the electronic control unit, a gradient of a road from the calculated vehicle acceleration and the longitudinal acceleration;

    calculating, by the electronic control unit, a resistance torque based on the estimated gradient of the road; and

    controlling, by the electronic control unit, traveling and stoppage maintenance of a vehicle using the calculated resistance torque.
