Abstract

A method of estimating the slope of a road surface on which is positioned a motor vehicle. The slope is determined by measuring the velocity and longitudinal acceleration of the vehicle by means of a mathematical model based on the relation Ax={dot over (ν)}+g sin α, where Ax is longitudinal acceleration, {dot over (ν)} indicates the component of longitudinal acceleration of the vehicle along the road surface, g is the gravitational acceleration, and α represents the angle of inclination of the road surface.
