Abstract: An exemplary self-balancing air spring includes a first chamber, the first chamber defining a primary volume, the first chamber including a movable piston, a second chamber fluidicly coupled to the first chamber via a first orifice and a second orifice, the second chamber defining a secondary volume, and an actuator coupled to the movable piston. In some aspects, the first orifice is an electromechanical valve and the second orifice is a bleed valve that equalizes the pressure between the first and second chambers.

Abstract: In accordance with certain embodiments, a vehicle is provided that includes a location system, an operation system, and a processor. The location system is configured to obtain location data pertaining to the vehicle. The operation system is configured to provide a feature for operation of the vehicle. The processor is coupled to the location system and the operation system, and is configured to: identify a point of interest in proximity to the vehicle based on the location data; determine a category to which the point of interest belongs; and provide instructions for the operation system to initiate a setting for the feature for operation of the vehicle based on the category for the point of interest that is in proximity to the vehicle and a history of the vehicle.

Abstract: Embodiments discussed herein enable detection of traction steer using measured and expected values of steering system data, such as, for example and without limitation, motor current, motor torque, motor position, motor velocity, steering wheel angle, and steering column torque. In some embodiments, the measured steering system data is compared to expected signal values, based on vehicle operating conditions, to determine if the vehicle is experiencing a traction steer event. In some embodiments, using known relationships between two or more steering system signals, a traction steer event is identified if an unexpected relationship is determined.
