Patent number: 12241430Abstract: A method for diagnosing a heating element of an exhaust gas sensor of an internal combustion engine. The exhaust gas sensor includes a temperature measurement device. A modeled temperature at the point of the exhaust gas sensor is continuously ascertained with the aid of a temperature model. The temperature of the exhaust gas sensor is increased by a heating process. The diagnosis of the heating element of the exhaust gas sensor is provided as the result an enable condition. Upon enablement of the diagnosis, a temperature difference between the modeled temperature of the exhaust gas sensor and the measured temperature of the exhaust gas sensor are ascertained. The heating element of the exhaust gas sensor is recognized as defective when the ascertained temperature difference exceeds a predefinable temperature threshold value.Type: GrantFiled: October 4, 2022Date of Patent: March 4, 2025Assignee: ROBERT BOSCH GMBHInventors: Lukas Cooke, Stefan Haller

Publication number: 20220214305Abstract: A method for ascertaining an internal resistance of a sensor element. The method includes: ascertaining a reference voltage between a first electrode and a second electrode; impressing of a first current pulse having a first current by a pulse-generating unit at a first time; ascertaining at least two voltage values at two different times after an elapsing of a first settling time after the first time; ending the first current pulse and impressing an opposite second current pulse having a second current at a second time, ending the second current pulse at a third time; ascertaining a linear equation as a function of the at least two voltage values and the times; extrapolating a voltage value at the first time using the linear equation; ascertaining an internal resistance of the sensor element as a function of the extrapolated voltage value, the reference voltage, and the first current.Type: ApplicationFiled: December 21, 2021Publication date: July 7, 2022Inventors: Anne-Katrin Mittasch, Stefan Haller

Patent number: 10830314Abstract: A motor shaft of an electric motor is produced by producing and interconnecting a first module and an additional module of the motor shaft. The first module of the motor shaft and/or the additional module of the motor shaft is or are provided with a module-end connection element by cold forming and/or by warm forming and/or by hot forming a base module. The first module of the motor shaft produced in this way and the additional module of the motor shaft produced in this way are then interconnected by joining the module-end connection elements on both ends. A motor shaft produced according to this method is formed of a correspondingly configured first module and a correspondingly configured additional module.Type: GrantFiled: October 25, 2017Date of Patent: November 10, 2020Assignee: FELSS Systems GmbHInventors: Michael Marré, Arthur Fauth, Stefan Haller, Serjosha Heinrichs, Henning Wagner

Patent number: 10782397Abstract: The disclosure relates to an approximate determination of a distance between a wireless key which is assigned to a motor vehicle and a transceiver arrangement which is disposed in or on the motor vehicle. In the course of a ranging cycle, a first first path relating to a first threshold value and a second first path relating to a higher, second threshold value are calculated. Two distances are estimated on the basis of this dual first path calculation.Type: GrantFiled: March 14, 2018Date of Patent: September 22, 2020Assignee: Continental Automotive GmbHInventors: Thomas Reisinger, Stefan Haller, Daniel Knobloch, Wolfgang Kuechler, Frank Leong
