1. A method for controlling a suspension system of a vehicle, comprising:
- receiving, by a processor, sensor data from a laser beamer, the sensor data including points that define elevation changes of a roadway in an upcoming path of the vehicle;
determining, by a processor, a continuous road profile based on the sensor data points;
computing, by a processor, one or more predicted vehicle motion values for each sensor data point in the continuous road profile based on a state space model of the vehicle;
determining one or more indicators of vehicle motion based on the vehicle motion values; and
selectively controlling, by a processor, at least one suspension element of the vehicle based on the one or more indicators of vehicle motion.

8. A system for controlling a suspension system of a vehicle, comprising:
-
at least one laser beamer sensor that generates sensor signals based on conditions of a roadway in upcoming path of the vehicle, the sensor signals including points that define elevation changes of the roadway in the upcoming path of the vehicle; and a control module that receives the sensor signals, that determines a continuous road profile based on the points, that computes one or more predicted vehicle motion values for each sensor data point in the continuous road profile based on a state space model of the vehicle, that determines one or more indicators of vehicle motion based on the one or more predicted vehicle motion values; and
that selectively controls at least one suspension element of the vehicle based on the one or more indicators of vehicle motion. - View Dependent Claims (9, 10, 11, 12, 13, 14)
