A method of estimating road slope of a vehicle may include determining an offset value of a gravitational acceleration sensor, determining a driving distance in a longitudinal direction of the gravitational acceleration sensor, comparing a difference between a driving distance and the driving distance in the longitudinal direction of the gravitational acceleration sensor with a predetermined value, estimating a road slope by using either a driving torque or the gravitational acceleration sensor based on a result of the comparison, and controlling a shift of the vehicle according to the estimated road slope.
