Publication number: 20230068156Abstract: A method for detecting a wear-relevant load on a vehicle wheel uses a tire pressure monitoring unit mounted on the vehicle wheel containing an acceleration sensor. A rotational frequency of the vehicle wheel is determined for a time interval from a series of measured values of the acceleration sensor at first time intervals. A centrifugal acceleration value is determined for the time interval. A proportionality factor is determined from the rotational frequency and centrifugal acceleration value, linking the square of the rotational frequency with the centrifugal acceleration. A rotational frequency of the wheel is continuously calculated from measured values of the centrifugal acceleration, which have been determined at second time intervals that are greater than the first time intervals, and from the proportionality factor. A load value is respectively calculated from the rotational frequency and the second time intervals. These load values are continuously added up to an overall load.Type: ApplicationFiled: August 15, 2022Publication date: March 2, 2023Applicant: Huf Baolong Electronics Bretten GmbHInventors: Markus Wagner, Patrick Voegeli

Publication number: 20220080788Abstract: A tire pressure monitoring unit is for mounting on a vehicle wheel, having a sensor for measuring the tire pressure, a transmitter and a receiver for wireless data transmission, a memory for storing tire data, and a controller connected to the sensor, the transmitter, the receiver and the memory. The controller writes this tire data into the memory on receipt of tire data received via the receiver and assigns a value to a variable, the value marking this tire data as valid. It is provided that a necessary condition for the variable to be assigned a value which marks the tire data as invalid is that the controller detects a pressure increase that exceeds a predetermined threshold value. In addition, a corresponding method for managing tire data in a data memory of a tire pressure monitoring unit is described.Type: ApplicationFiled: November 24, 2021Publication date: March 17, 2022Applicant: Huf Baolong Electronics Bretten GmbHInventors: Carsten Dederer, Christian Walter

Patent number: 11155127Abstract: A tire pressure monitoring unit is mounted on a vehicle wheel having a pressure and acceleration sensor. A method for assigning wheel positions includes pressure and acceleration data determined from the sensors. The pressure data and at least one piece of information derived from the acceleration data are transmitted wirelessly in a data telegram together with a characteristic identifier. Information concerning the reliability of the information derived from the acceleration data is acquired in the tire pressure monitoring unit on the basis of the measurements and is transmitted with the data telegram. A central evaluation unit considers a plurality of data telegrams and, taking account of data from the ABS sensors, assigns the individual tire pressure monitoring units to wheel positions. Data telegrams in which the reliability is higher receive a greater weighting, and data telegrams in which the reliability is smaller receive a smaller weighting.Type: GrantFiled: April 25, 2019Date of Patent: October 26, 2021Assignee: HUF BAOLONG ELECTRONICS BRETTEN GMBHInventors: Markus Alexander, Markus Wagner

Patent number: 10442255Abstract: A method for assigning identifiers of wheel electronics to the positions of the wheels on the vehicle is disclosed. The wheel electronics send their individual identifier with information relating to the rotational direction of the wheel and to the occurrence of an impact on the wheel to a receiver. An evaluation unit: collects the identifiers and rotational direction information and the driving speed, and on this basis, differentiates between identifiers of wheel electronics on the left and right vehicle side; differentiates impacts reported from wheel electronics on the left vehicle side, from impacts reported from wheel electronics on the right vehicle side; measures the time between impact signals reported from wheel electronics on the left or on the right vehicle side; multiplies the measured time by the driving speed measuring during this time; and checks whether the length formed by the multiplication coincides with an axle distance.Type: GrantFiled: March 14, 2018Date of Patent: October 15, 2019Assignee: HUF BAOLONG ELECTRONICS BRETTEN GMBHInventors: Markus Alexander, Ralf Kessler, Markus Wagner
