Pressure supply diagnostics and controls and the tire inflation system made therewith

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.

Dual tire pressure monitor and wheel torque sensor for vehicles
10807420 · 2020-10-20 · ·

A dual tire pressure monitoring system (TPMS) and wheel torque sensor system generates a single wireless signal containing both tire pressure data and wheel strain data. The wheel strain data is functionally related to wheel torque. The dual sensor has a transceiver that generates the wireless signal for a remote controller. A body of the dual sensor is positioned on the interior of the wheel under the tire, near the valve stem. The wheel torque is used to control braking, propulsion or steering of a Highly Automated Driving (HAD) vehicle, and to improve vehicle stability control and vehicle diagnostics.
