Abstract: A method for diagnosing an air filter status includes receiving, by a controller, sensor data indicative of a mass air flow rate, an air temperature and an air pressure of an air cleaner assembly including an air filter, determining an air filter life remaining from the sensor data, and receiving data indicative of a vehicle condition. The method also includes determining when a first condition is satisfied and when true, triggering an air filter leakage alert. When the first condition is not satisfied, the controller determines when a second condition is satisfied. When the second condition is satisfied, the controller determines when a third condition is satisfied, and when the third condition is satisfied, triggers an air filter snow intrusion alert. When the second condition is satisfied and the third condition is not satisfied the controller triggers an air filter blockage alert.

Abstract: Examples of techniques for determining tire leak rate are disclosed. In one example implementation, a method includes receiving, by a processing device, temperature data, pressure data, tire characteristics, and an estimated leak rate associated with the tire. The method further includes calculating, by the processing device, a temperature normalized fused pressure after fusing the temperature data and the pressure data. The method further includes determining, by the processing device, the tire leak rate based at least in part on a decay of the temperature normalized fused pressure over time. The method further includes providing, by the processing device, an alert to an operator of the vehicle that a leak is detected based at least in part on a comparison between the tire leak rate and a leak rate threshold.

Abstract: A tire assembly includes a reservoir, a tire, and a pressure module. The pressure module includes a first valve, a second valve, and a control unit. The first valve selectively directs air from the reservoir to the interior cavity. The second valve directs air from the interior cavity of the tire to the atmosphere. The control unit is configured to selectively send a first control signal to the first valve such that the first valve cycles from a first position, at which air is prevented from flowing from the reservoir to the interior cavity, to a second position, at which air is allowed to flow from the reservoir to the interior cavity of the tire. The control unit is configured to selectively send another first control signal to the first valve such that the first valve cycles from the second position to the first position.

Abstract: A wheel braking system includes a fluid source connected to an actuator that applies a force to a friction element for retarding rotation of the wheel. The braking system also includes a hydraulic circuit that has a first fluid passage providing direct communication between the fluid source and the actuator and a second fluid passage in communication with the first passage. The second fluid passage has a first portion and a second portion and includes a reciprocating piston assembly with a first piston fixed to a second piston for selectively amplifying a volume of the pressurized fluid received by the actuator. The first portion of the second passage is in fluid communication with the first piston and the second portion is in fluid communication with the second piston. The first piston has a first diameter and the second piston has a second diameter that is greater than the first diameter.

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.
