ROAD SLOPE ESTIMATION METHOD FOR A VEHICLE

Proposed is a road slope estimation method for a vehicle. The method includes: calculating, by a controller, a basic slope based on an output value of an acceleration sensor of the vehicle; calculating, by the controller, an acceleration/deceleration correction value from an acceleration/deceleration correction map; and calculating, by the controller, a turning correction value from a turning correction map. The method further includes: calculating, by the controller, a final slope based on the basic slope, the acceleration/deceleration correction value, and the turning correction value; and controlling the vehicle based on the final slope.
