摘要： A method for operating a sensor in an exhaust gas tract of an internal combustion engine and a device for carrying out the method are provided. In the method, a diagnosis is carried out of the condition of the saturation temperature, exclusively while taking into consideration a few fundamental input variables characterizing the operating state of the internal combustion engine.

摘要： A method for detecting combustion misses in a multi-cylinder internal combustion engine. The control units of the engine use an engine control program which is interrupted by interrupt routines, in phase-synchronism with the rotational movement of the crankshaft, in which at least the data required for injection and firing are processed. The detection of combustion misses includes establishing and evaluating crankshaft segment times in which the crankshaft covers an associated circle-segment angle range. The crankshaft segment are also established and evaluated in particular interrupt routines, and for the further subset of cylinders in the interrupt routines in which their firing is controlled. Furthermore, the crankshaft segment times for the first cylinder is established and evaluated in certain additionally generated interrupt routines.

摘要： A method and a device for modifying data and programs and for writing the data and programs into at least one first non-volatile memory of a computer system, in particular a memory of a control unit of a vehicle. In this context, the data and programs are divided into at least first and second data and programs, at least the second data and programs being worthy of backup, or containing backup-worthy data and programs. However, the old second data and programs in the assigned original sector are not erased until new second data and programs are written into a second memory sector not corresponding to the original sector, and a copying program is written into a second volatile memory. The copying program writes the new second data and programs from the second memory sector into the original sector. As a result, there is no need to create a backup copy of the backup-worthy data and programs. Thus, the old second data and programs are not erased by an erase command sent by a programming unit, and they then assume execution of the sequencing control.

摘要： A tampering-protected microprocessor system includes a microprocessor, an internal write/read memory integrated with the microprocessor into a common module, and a second memory in which at least a portion of an operating program to be executed by the microprocessor is stored. At least one procedure of the operating program which is indispensable for the function of the microprocessor system is stored in encrypted form in the external memory. The operating program includes a decryption procedure which decrypts each encrypted procedure of the operating program and stores it in the internal write/read memory. The indispensable procedure, in order to function properly, requires a successful execution of an integrity test procedure which tests the integrity of at least a portion of the operating program.
