Abstract: PURPOSE: A slope control method of a constant-velocity traveling vehicle is provided to restrict noise of an engine caused by the change of frequent TPS(Throttle Position Sensor) values on the slope and frequent shifts generated in the sudden rise of TPS. CONSTITUTION: In a slope control method of a constant-velocity traveling vehicle, constant-velocity managing tolerance becomes one mile when the vehicle travels on the level ground.
