Publication number: 20170153127Abstract: The disclosure relates to a method for determining a corrected rotation angle of a raw rotation angle recorded using an angle sensor which, on the basis of the raw rotation angle, outputs first and second raw rotation angle signals which have a periodic profile and are in an orthogonal relationship with one another. A deviation from the orthogonal relationship between the sensor signals can occur based on the error. The method includes: determining a correction value by means of a determination unit for determining the correction value and making the correction value available to a correction unit, applying the correction value to at least one of the raw rotation angle signals by means of the correction unit for determining at least one corrected rotation angle signal, and calculating the corrected rotation angle using at least one of the corrected rotation angle signals.Type: ApplicationFiled: February 14, 2017Publication date: June 1, 2017Applicant: CONTINENTAL AUTOMOTIVE GMBHInventors: Jens Gleissberg, Markus Irth

Patent number: 8397559Abstract: A system and method for indirect tire pressure monitoring. A pressure loss variable (X, f, c) is determined based on an analysis of an oscillation behavior of a tire of a motor vehicle for the detection of a pressure loss in the tire of a wheel.
