Patent number: 11909821Abstract: Embodiments of the invention relate to the processing of a safety-related user program for a safety control system. The generation of the machine code for the safety-related control takes place on a cloud computer. The data required for generating the machine code such as the source code data of the user program, are secured with a unique signature and transmitted to the cloud computer. The machine code is generated on the cloud computer from the transmitted data. A new signature is generated via the resultant data and the signature from the preceding step. The entire safety life cycle is also covered, since each step in the life cycle is automatically documented and may be clearly tracked at any time, and corruptions of a step may be detected.Type: GrantFiled: November 7, 2019Date of Patent: February 20, 2024Inventors: Tobias Frank, Harry Koop, Julian Bartel

Patent number: 11293365Abstract: A method for operating an internal combustion engine, including aligning an injection behavior of the number of injectors. Aligning the injection behavior includes switching off one injector of the number of injectors, detecting a signal of the internal combustion engine that is to be assigned to the switched off injector, determining an alignment characteristic from the signal and assigning the alignment characteristic to the switched off injector as an alignment characteristic assigned to the injector, and switching on the previously switched off injector. Aligning the injection behavior further includes performing the aforementioned steps sequentially for the other injectors of the number of injectors and correcting a control of an injector that is to be corrected using the measured value assigned to the injector that is to be corrected.Type: GrantFiled: December 22, 2020Date of Patent: April 5, 2022Assignee: Rolls-Royce Solutions GmbHInventors: Tobias Frank, Jörg Remele, Aron Toth

Patent number: 11149664Abstract: A method for monitoring a cylinder pressure sensor, in which method the sensor value is checked for admissibility and inadmissibility in a predefinable crankshaft angle range, when admissibility is detected the cylinder pressure sensor is used further and when inadmissibility is detected the cylinder pressure sensor is deactivated. A first sensor value of the cylinder pressure sensor is set as a start value, and a second sensor value is set as a stop value, a plateau range is determined from the number of sampling steps between the start value and the stop value, and the plateau range is set as decisive for the admissibility or inadmissibility of the sensor values.Type: GrantFiled: May 3, 2018Date of Patent: October 19, 2021Assignee: MTU FRIEDRICHSHAFEN GMBHInventors: Tobias Frank, Aron Toth, Horst Weidele
