PURPOSE: A road slope method is provided to measure sense an angle of inclination of a driving road, not with s special sensor, but with a compensational signal, a revised control signal based on differences between an engine drive RPM under the engine idling and a targeted RPM. CONSTITUTION: The road slope method includes an idle and brake verification step(S1), in which a controller electrically connected to an engine and a foot break switch is checked to verify if it is set in the idle state, and then motions of the foot break switch are checked, a control signal verification step(S2),in which a controller applying actual drive RPM by the targeted RPM and the control signal corresponding to the targeted RPM verifies whether a correction value of a control signal generated due to differences between the targeted RPM and the actual drive RPM, when the foot break switch is switched off after the engine is the idle state, and an angle of inclination decision step (S3), in which the controller calculates the angle of inclination of the driving road based on the correction value, when the correction value of the control signal is generated. |
