A method of road slope estimating by using a gravitational acceleration sensor includes determining whether a condition of estimating the road slope by using the gravitational acceleration sensor is satisfied; estimating the road slope by using the gravitational acceleration sensor and updating the road slope when a condition of estimating the road slope by the gravitational acceleration sensor is satisfied; comparing a change rate of the estimated road slope with a first predetermined value; comparing a difference between the estimated road slope and a filtered road slope with a second predetermined value when the change rate of the estimated road slope is greater than or equal to the first predetermined value; and filtering the estimated road slope by changing a coefficient of the filter when the difference between the estimated road slope and the filtered road slope is greater than or equal to the second predetermined value.
