Classification: CPC B | IPC B

Claim 46:
47. A profiling system arranged to be used in cooperation with a vehicle, the profiling system comprising:
one or more sensors to collect data and one or more processors to process the data, the one or more sensors and the one or more processors cooperating to:
generate inertial profile data of a road surface traveled by, or adjacent to, the vehicle, the inertial profile data having long wavelength inertial profile components and short wavelength inertial profile components, wherein the long wavelength inertial profile components are longer than the short wavelength inertial profile components;
generate a vehicle elevation profile;
generate running slope profile data from the vehicle elevation profile and height sensor information, the running slope profile data having long wavelength running slope profile components and short wavelength running slope profile components, wherein the long wavelength running slope profile components are longer than the short wavelength running slope profile components; and
generate a valid profile of the road surface, without any minimum speed requirement of the vehicle, by:
filtering the inertial profile data to obtain the short wavelength inertial profile components and filtering the running slope profile data to obtain the long wavelength running slope profile components; and
generate the valid profile of the road surface, without any minimum speed requirement of the vehicle, by blending the short wavelength inertial profile components of the inertial profile data and the long wavelength running slope profile components of the running slope profile data.
