Method for estimating the longitudinal inclination of a roadway

摘要

A method and device for determining a longitudinal inclination variable representing the longitudinal inclination of a roadway, using a sensor "means" present in a motor vehicle, in which a first unbraked driving state of the vehicle and a second driving state of the motor vehicle in which at least one brake is actuated are considered; and as a function thereof the variable representing the longitudinal inclination of the roadway is determined.
