1. An apparatus comprising:
interface circuitry;
machine readable instructions; and
programmable circuitry to at least one of instantiate or execute the machine readable instructions to:
determine a terrain condition based on first wheel position data of a vehicle and second wheel position data of the vehicle, the determination of the terrain condition including:
generating filtered wheel position data by filtering the first wheel position data and the second wheel position data via a high-pass filter; and
calculating a power spectral density of the filtered wheel position data;
determine a damping command based on the terrain condition; and
adjust a suspension of the vehicle based on the damping command.
