Abstract
Actuator assemblies and methods and systems for using the same. One actuator assembly includes an actuator, and a controller. The controller is configured to receive a command signal from a vehicle electronic control unit, receive a data signal from a sensor, determine a control signal for the actuator based on the command signal from the vehicle electronic control unit and the data signal from the sensor, transmit the control signal to the actuator, determine a status signal based on the control signal, and transmit the status signal to the vehicle electronic control unit.

21. A method of controlling a vehicle, the method comprising:
-
receiving, by a first controller, an input signal representing vehicle operating parameters; receiving, by the first controller, a target displacement determined by a second controller for a first suspension system of the vehicle; determining, by the first controller, a target displacement for a second suspension system of the vehicle based on the target displacement received from the second controller and the input signal; and setting a height of the second suspension system based on the target displacement determined by the first controller for the second suspension system. - View Dependent Claims (22, 23, 24, 25)
