Abstract
Methods and systems are provided for controlling a suspension system of a vehicle. In one embodiment, the method includes: receiving, by a processor, sensor data indicative of conditions of a roadway in a path of the vehicle; determining, by a processor, a continuous road profile based on the sensor data; and selectively controlling, by a processor, at least one suspension element of the vehicle based on the continuous road profile.
Claims14
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.
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.
