Abstract: Techniques for using ball joint sensor data to determine conditions relevant to a vehicle are described in this disclosure. For example, in one example, the ball joint sensor data may be used to determine a ride height at a portion of the vehicle, which may be used to determine roll data and/or pitch data. The ride height, roll data, and/or pitch data may be directly used to navigate through an environment, such as by the vehicle relying on the data when interpreting sensor data or planning driving operations. Also, the ride height, roll data, and/or pitch data may be used to verify the reliability of other sensor data used to navigate through the environment.

Abstract: A suspension system for controlling movement of a vehicle wheel may include a spring and damper assembly coupling the wheel to the vehicle chassis for movement of the wheel relative to the vehicle chassis. The spring and damper assembly may include a spring coupled to a damper member configured to extend and retract the wheel relative to the vehicle chassis. The suspension system may further include a damper actuator located remotely from the spring and damper assembly and configured to modify an amount of damping and/or wheel extension. The suspension system may also include a spring actuator integrated with the damper actuator and configured to control an amount of deflection of the spring and/or to alter a spring rate. The damper actuator may be provided at a location in the vehicle separated from the spring and damper assembly.

Abstract: A suspension system may include a pneumatic spring at each wheel of a vehicle. The suspension system may be configured to determine and achieve a pressure set point in each of the pneumatic springs and a target ride height at each wheel of the vehicle. The pressure set point may be determined based on a load at each of the wheels and the center of gravity of the vehicle, such that upon reaching the pressure set point at each in each of the pneumatic springs, a target load and target ride height may be achieved at each of the wheels of the vehicle. The system may also be used to level the ride height of the vehicle and/or achieve a desired orientation.
