Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for sampling data on the gradient of a road surface, for use in a road travel simulating test method using a chassis dynamometer, whereby the gradient of the road surface can be determined very easily. SOLUTION: An atmospheric pressure sensor 9 is mounted in a vehicle 1, which is made to travel on a road. A variation in height is calculated from short-term changes in atmospheric pressure during travel on the road, and the gradient of the road surface 18 relative to the traveled distance is measured from the variation in height in every traveled distance, to sample data on the gradient of the road surface 18.
