Patent number: 11707950Abstract: Sensor and method for determining operating states associated with one or more tires. The operating state of the tire can be determined based on one or more measures environmental conditions of the tire(s). For example, a controller can be configured to determine a change in one or more environmental conditions, including determining, for example, a rate-of-change value, a variance value, a standard deviation, or the like. The rate-of-change, variance, and/or standard deviation values can be compared to one or more threshold values to determine the operating state(s) associated with the tire(s). The environmental condition can include, for example, acceleration of the tire, pressure of the tire, and/or temperature of the tire. The operating state can be, for example, a filling state indicative of the tire being inflating, and/or a drive state indicative of the tire rotating about its axle.Type: GrantFiled: May 26, 2021Date of Patent: July 25, 2023Assignee: Infineon Technologies AGInventors: Christoph Steiner, Ralf-Rainer Schledz

Patent number: 8700286Abstract: Embodiments relate to tire localization in tire pressure monitoring systems (TPMS). In embodiments, a TPMS includes a wheel unit and a control unit. Each wheel unit collects acceleration data and transmits that data to the control unit for processing. The control unit processes the data and, using additional data received from another vehicle system, for example an antilock braking system (ABS) or electronic stability control (ESC) system, correlates the data in order to localize each wheel unit to a particular wheel of the vehicle. Advantages include increased processing power at the control unit as compared to the wheel unit.Type: GrantFiled: December 21, 2011Date of Patent: April 15, 2014Assignee: Infineon Technologies AGInventors: Christoph Steiner, Ralf-Rainer Schledz
