Patent number: 11541702Abstract: A method of determining the health of a tire on a vehicle includes determining a total number of tire inflation events that have occurred due to a loss of tire pressure. A rate in which the tire inflation events have occurred is determined based on the total number of tire inflation events over a predetermined period of time. The health of a tire is determined by comparing the rate in which tire inflation events have occurred to a threshold rate.Type: GrantFiled: January 16, 2020Date of Patent: January 3, 2023Assignee: Dana Heavy Vehicle Systems Group, LLCInventors: Venkata Ramakanth Kona, Christopher P.

Patent number: 10828940Abstract: A method of decreasing tire pressure includes opening a wheel valve (22) to allow pressurized air from a tire (10) to be directed to a first valve assembly (14) and to atmosphere. A target pressure is selected for a fluid control conduit (28). The fluid conduit (28) is in fluid communication with the first valve assembly (14) and a second or control valve assembly (30). The pressure in the fluid conduit (28) is measured. If the measured pressure is greater than the target pressure, then the second valve assembly (30) is de-energized. If the measured pressure is less than the target pressure, then the second valve assembly (30) is energized. A valve (42) prone to leak under very low temperatures may be subjected to repeated cycles of pressure application and pressure release in order to form a fluid-tight seal.Type: GrantFiled: May 18, 2016Date of Patent: November 10, 2020Assignee: DANA HEAVY VEHICLE SYSTEMS GROUP, LLCInventors: Kurt P. Gillen, Venkata Ramakanth Kona

Patent number: 10807419Abstract: A method of determining tire pressure includes providing a control unit having a first pressure transducer. The control unit is in fluid communication with a fluid reservoir via an air supply circuit. A second pressure transducer is disposed at least partially within the fluid reservoir. The method also includes measuring a pressure of air in the air supply circuit utilizing the first pressure transducer and measuring a pressure of air in the reservoir utilizing the second pressure transducer. The method additionally includes determining a difference in the measurements of the first pressure transducer and the second pressure transducer and calibrating the second pressure transducer pressure measurement to agree with the first pressure transducer pressure measurement where the pressure difference is less than a predetermined value. The method further includes measuring a pressure in one or more tires.Type: GrantFiled: April 18, 2018Date of Patent: October 20, 2020Assignee: DANA HEAVY VEHICLE SYSTEMS GROUP, LLCInventor: Venkata Ramakanth Kona

Patent number: 9403410Abstract: A method for decreasing tire pressure includes providing a wheel assembly which defines a chamber that houses a pressurized fluid. A wheel valve assembly is provided in fluid communication with the chamber. The wheel valve assembly is operable between an open position and a closed position and includes an area having a first flow capacity. A variable area valve assembly is provided and is selectively in fluid communication with the wheel valve assembly. The variable area valve assembly includes an area formed in a perforation that has a second flow capacity. The second flow capacity is less than the first flow capacity. A target tire pressure is selected. If a pressure of the pressurized fluid in the chamber is greater than the target tire pressure, then the pressure of the pressurized fluid in the chamber is decreased.Type: GrantFiled: February 24, 2016Date of Patent: August 2, 2016Assignee: DANA HEAVY VEHICLE SYSTEMS GROUP, LLCInventors: Melvin B.
