Abstract: Examples of techniques for vehicle suspension system alignment monitoring are disclosed. In one example implementation, a method includes receiving vehicle data and environmental data including, inertial measurement unit (IMU) acceleration data and global positioning system (GPS) velocity data from a GPS associated with the vehicle, and steering wheel angle data, driver applied torque data, and electronic power steering (EPS) applied torque data associated with the steering system. The method further includes mitigating for at least one of a vehicle effect and an environmental effect based on the vehicle data and environmental data. The method further includes detecting a misalignment based at least in part on one or more of the IMU acceleration data, the GPS velocity data, acceleration data, a steering wheel angle, and a self-aligning torque. The method further includes reporting the misalignment of the vehicle based at least in part on detecting the misalignment.

Abstract: A tank assembly includes a tank having a plurality of tank walls surrounding an interior cavity. The interior cavity is configured to store a fluid. The fluid is configured to expand upon a change in temperature. A fill channel and a vent channel are each in fluid communication with the interior cavity. At least one compressible member is positioned within the interior cavity and configured to provide an expansion space for the fluid. The compressible member eliminates the need to be concerned with a loss of air space when filling the tank with low flow rates and when filling on grades. The compressible member may be composed of a closed cell foam material. Alternatively, the compressible member may include a pouch having a hollow space surrounded by an outer skin.
