Abstract: A method for monitoring a knock control and a device for knock control of an internal combustion engine are provided, in which digital knock data are obtained for the knock control in that the acquisition of data of a knock sensor, converted from analog to digital, is started at a start angle of the internal combustion engine and ended at an end angle. The digital knock data are evaluated so as to detect a malfunction in the acquisition of the digital knock data.

Abstract: A method and a device for selecting a function which is implemented at a terminal of the device. The device includes a processor and a first function path over which a first function is implemented, and includes at least one other function path over which another function is implemented. The function paths run over at least two different terminals of the processor, and the at least two function paths are connected and are routed directly to the single terminal of the device. The selection of the function to be implemented is made by a predefinable code, and the at least second function is suppressed.

Abstract: A method for operating an internal combustion engine is described, in which the ambient pressure is determined by an ambient pressure sensor and the pressure in an intake manifold of the internal combustion engine is determined by an intake manifold pressure sensor. In this method the reliability performance of the ambient pressure sensor is checked by comparing the ambient pressure to a starting value that is obtained by the intake manifold pressure sensor before a starting process of the internal combustion engine. The comparison is only performed if a preceding check of the intake manifold pressure sensor yields the result that it is operational.

Abstract: A method and a device for controlling a drive unit, in particular, of an internal combustion engine in a vehicle, in which at least one performance quantity of the drive unit is detected and at least one actuator of the drive unit is controlled with controlled variables, depending on this performance quantity, according to predefinable or preselectable functionalities. In a controller, at least two processors process the possible functionalities, where these functionalities are defined by program code in at least one assigned program memory per processor. These possible functionalities of the processors, i.e., the program codes in the program memories assigned to the processors are identical.

Abstract: A method and a device for controlling processes with the help of process quantities in conjunction with a drive, in particular an engine for driving a vehicle, the processes being executed and controlled at the time the drive is shut off and/or thereafter, and the power supply to the processes and control being maintained by an energy storage devices at the time the drive is shut off and/or thereafter, the processes being controlled by at least two processors and the first processor disconnecting the at least second processor and itself from the power supply when the process quantities of the processes assigned to the respective processors each meet at least one predefinable condition.

Abstract: Method and device for controlling a process in a vehicle, in particular for controlling a drive in the vehicle, using at least one processor. Control functions are stored in the form of program code in a processor-addressable address space of at least one memory. The address space is divided into segments of equal length, and the program code is stored as program parts per control function in individual, consecutive sections in the segment. At least two segments are linked so that a section of a first segment is programmed as an exit label from the first segment, and a second section in the second segment is programmed as an entry label to the second segment. A transition from the exit label of the first segment to the entry label of the second segment brackets the code segments and thus expands the possible segment area.

Abstract: A method and a device for controlling processes in conjunction with an internal combustion engine having at least two combustion chambers, where control functions are executed by at least one processor, and the program code on which the control functions are based can be stored in at least one memory. At least one data record is assigned to the program code, and the control functions are implemented as a link between the program code and the at least one data record. The combustion chambers are grouped in at least two engine banks for control purposes, and one data record is assigned to each engine bank individually. The respective data record for implementing the control functions is selected as a function of the respective engine bank to be controlled. Thus, the data record is switched as a function of the engine bank.

Abstract: A method and an apparatus for controlling operations in a vehicle, at least two processors accessing at least one memory device and a simultaneous read and/or write access of the at least two processors to the identical address of the memory device during program execution being prevented. The identical address is detected by way of an address comparison, and as a function of this address comparison a signal is transmitted to at least one processor. In particular, a first signal is transmitted to a first processor and a second signal to a second processor. Program execution by at least one of the at least two processors is thereby brought to a halt by the signal, or the respective processor is halted.
