A method for detecting a slope of a road on which a vehicle is traveling in at least one spatial direction. The vehicle has a body and a chassis with a plurality of wheels. An inclination of the vehicle body in the spatial direction is determined. For at least one wheel, a vertical distance to the vehicle body is detected. The distance so determined is used to calculate an inclination of the chassis in the spatial direction. The slope of the road in the spatial direction is determined from a difference between the inclination of the vehicle body in the spatial direction and the inclination of the chassis in the spatial direction.
