    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 system and method to determine the health state of a damper associated with a wheel of a vehicle using indirect measurements obtain information from one or more sensors. The one or more sensors includes a wheel speed sensor, inertial measurement unit, tire pressure sensor, steering wheel sensor, global positioning system (GPS) receiver, or a camera. The information from at least one of the one or more sensors includes at least one measurement of a parameter not directly characterizing the damper. The method also includes comparing the at least one measurement of the parameter with data of the parameter to estimate wear of the damper. The data includes a historical measurement, a measurement for another wheel of the vehicle, a measurement from another vehicle, or an output of a model, and a maintenance or replacement task is triggered by the estimate of the wear of the damper.

    Abstract: A lateral stabilization assembly includes a chassis and a stabilizer bar coupled to the chassis. The stabilizer bar includes a central bar portion extending along a bar axis. The lateral stabilization assembly also includes first and second bearings coupled to the chassis. The lateral stabilization assembly also includes a first and second flanges fixed to the central bar portion. The first flange and the second flange are configured to allow a transfer of lateral loads between the first lateral side and the second lateral side of the chassis through the first bearing, the stabilizer bar, and the second bearing.

    Abstract: A brake pad life monitoring system can monitor the wear of a brake pad operatively coupled to a rotor. The brake pad life monitoring system includes an erodible, electrically non-conductive covering layer operatively coupled to the brake pad such that wear of the erodible, electrically non-conductive covering layer corresponds to the wear of the brake pad. Further, the brake pad life monitoring system includes an electrical circuit having a circuit path from a power supply to a ground. The electrical circuit is at least partially disposed on the erodible, electrically non-conductive covering layer and includes a first resistor connected in series with the power supply and a second resistor electrically connected in parallel with the power supply. The brake pad life monitoring system additionally includes a measuring device electrically connected to the electrical circuit.

    Abstract: A self-calibration method of determining remaining useful life of an internal combustion engine's air filter includes establishing a pressure drop versus mass airflow rate relationship for a clean air filter using pressure drop, mass airflow rate, and temperature data captured at low and elevated engine speeds. The method also includes establishing a maximum clean air filter pressure drop at a preset maximum airflow using the clean filter relationship. The method additionally includes establishing a pressure drop versus mass airflow rate relationship for an in-service air filter using pressure drop, mass airflow rate, and temperature data captured at low and elevated engine speeds. The method also includes determining a maximum in-service air filter pressure drop at the preset maximum airflow using the in-service filter relationship. The method further includes comparing the maximum clean and in-service air filter pressure drops to determine the remaining useful life of the in-service air filter.

    Abstract: A method of determining a volume of a fluid in a reservoir arranged in a vehicle includes assessing, via a controller, whether a first sensor operatively connected to the reservoir and configured to detect a predetermined level of the fluid in the reservoir has been triggered. The method also includes detecting, via a second sensor, a vehicle operative state indicative of inclination of a free surface of the fluid in the reservoir. The method additionally includes communicating, via the second sensor, the detected vehicle operative state to the electronic controller and determining a degree of inclination of the free surface of the fluid in response to the detected vehicle operative state. Furthermore, the method includes determining, via the controller, the volume of the fluid in the reservoir when the first sensor has been triggered in response to the determined degree of inclination of the free surface of the fluid.
