Abstract: A method for providing a timestamp in a real-time system, whereby the real-time system has an FPGA and a CPU, which cooperate with one another, and at least one register, which contains a system time, is implemented in the FPGA. The method includes the steps of providing a CPU counter for the system time, which is driven by a clock signal of the CPU, providing a synchronization counter in the CPU, whereby the synchronization counter is driven by a clock signal of the CPU, reading of the counter for providing the system time by a real-time application, querying the synchronization counter in the real-time application, and synchronizing the counter with the system time in the real-time application, when the synchronization counter outputs a value that corresponds to more than a predefined time period since the last synchronization of the CPU counter with the system time.

Abstract: A development system for creating a control unit program, in which a control unit program is configured to control an electronic control unit in a vehicle. The development system includes an electronic computer unit, which is configured to generate the control unit program. The development system includes an input unit assigned to the electronic computer unit and a display unit assigned to the electronic computer unit. The display unit has a first display area and a second display area. At least one build process step can be executed by means of the development system.

Abstract: A method for detecting a first rotation angle of a first shaft of an engine is provided, whereby a first marking carrier with sensor-readable markings is provided, whereby the markings form a first marking pattern that has marking sections having at least one first and a second marking section. The first marking carrier is scanned by a first sensor and a first sensor signal is generated. The first sensor signal is modulated by the markings on the marking carrier. A correlation between a time course of the first sensor signal and a time signal is made by a computing unit. A first marking section is recovered from the first sensor signal by the computing unit, and then, a first exclusion criterion for excluding the first stored marking section is determined from the recovered first marking section. The first stored marking section is then excluded by the first exclusion criteria.

Abstract: A method for real-time testing of a control unit for an internal combustion engine using a simulator is provided. The control unit and the simulator are connected to one another by a first data channel. The control unit transmits engine control data to the simulator through the first data channel and the simulator calculates engine state variables in real time on its first simulator processor with a first sampling step size and transmits at least some of the engine state variables to the control unit. Thus, selected engine state variables can be made available at a different frequency, and in particular at a higher frequency, than is possible by the first sampling step size of the first simulator processor, in that the simulator calculates at least one specific engine state variable using a partial engine model and with a second sampling step size different from the first sampling step size.
