Abstract:
A vehicle, variable spring system and method of operating a corner actuator coupled to wheel of the vehicle. The vehicle includes the corner actuator and the variable spring system. The variable spring system includes a control chamber coupled to the corner actuator, a first spring, a second spring, and a valve. An applied resistance for the corner actuator is selected by selecting an amount of fluid coupling between the control chamber and each of the first spring and the second spring. A force is absorbed at the wheel using the applied resistance.
