Hybrid Straßengradientenermittlungssystem

摘要

A method for controlling the operation of a hybrid vehicle traveling on a lane with a gradient includes determining a driving force of the hybrid vehicle, calculating a brake pressure value, and determining whether a gradient-locked state exists based on the brake pressure value. The method further comprises calculating, based on the driving force, a gradient value of the road surface when the locked state does not exist, and controlling the operation of the hybrid vehicle based on the gradient value.
