Field: Transport (Mechanical engineering)
Classification: CPC B | IPC B

Claim 0:
1. A profiling system configured to be used in cooperation with a vehicle, the profiling system including one or more processors and one or more sensors, the one or more processors configured to:
(a) process data collected by the one or more sensors, the data collected by the one or more sensors indicative of a surface traveled by, or adjacent to, the vehicle, the data collected by the profiling system processed by the one or more processors to generate:
inertial profile data; and
running slope profile data;
(b) filter the inertial profile data to remove long wavelength inertial profile data components using a high-pass filter having a high-pass cutoff to obtain select short wavelength inertial profile data components of the inertial profile data;
(c) filter the running slope profile data to remove short wavelength running slope profile data components using a low-pass filter having a low-pass cutoff to obtain select long wavelength running slope profile data components of the running slope profile data;
(d) blend the select short wavelength inertial profile data components from the inertial profile data and the select long wavelength running slope profile data components of the running slope profile data, and
(e) generate a valid surface profile of the surface, without a minimum speed requirement for the vehicle, from the blended select short wavelength inertial profile data components of the inertial profile data and the select long wavelength running slope profile data components of the running slope profile data.
