A method for controlling a technical system, in particular of a motor vehicle.

Device and method for controlling a technical system

A method for operating a control unit for an exhaust gas probe, in particular a broadband Lambda probe for an internal combustion engine, in particular of a motor vehicle. The control unit is designed for the electrical actuation of the exhaust gas probe, and the control unit in particular being implemented in the form of an application-specific integrated circuit, ASIC. The method includes: specifying control data for an operation of the control unit and/or the exhaust gas probe with the aid of a processing device; receiving operating data which characterizes the operation of the control unit and/or the exhaust gas probe with the aid of a processing device.

A method for detecting an unauthorized physical access to a bus system. The method including: acquiring a measuring signal which assumes a first state when the voltage signal lies above a threshold voltage and a second state when the voltage signal does not; detecting a test-level sequence in the voltage signal; forming a measuring-signal pattern based on the measuring signal; comparing the measuring-signal pattern to a reference pattern that is assigned to the detected test-level sequence and was determined based on a reference measuring signal for the test-level sequence in a state of the bus system in which no unauthorized physical access was present; and determining that a possible unauthorized physical access is present if the measuring-signal pattern and the reference pattern differ from each other in one or more predetermined properties by more than a specific tolerance.

Method for detecting an unauthorized physical access to a bus system

A method for accessing data in an external memory of a microcontroller, the microcontroller having an internal memory. The method includes: providing a classification data record in the internal memory, the classification data record for data stored in segments in the external memory including a segment-data classification for each segment, the segment-data classification characterizing the data stored in the respective segment; and a read access in which data corresponding to a predetermined data classification are read from the external memory. The read access includes checking a segment, the segment-data classification of the segment being read from the internal memory during the checking and being compared to the predetermined data classification, and: if the segment-data classification read corresponds to the predetermined data classification, reading the data stored in the segment from the external memory, or, if the segment-data classification does not correspond, resuming with the checking step for a further segment.

Method for accessing data in an external memory of a microcontroller

A method for detecting an unauthorized physical access to a bus system. The method includes detecting a test level sequence in the voltage signal; constituting a binary sampled pattern by sampling the voltage signal at specified pattern times associated with the detected test level sequence, and assigning a first value if the voltage signal is above a predefined voltage threshold at the respective pattern time, and a second value if the voltage signal is not above the voltage threshold; comparing the sampled pattern with a reference pattern that is associated with the detected test level sequence and that was constituted for the test level sequence as a sampled pattern in a state of the bus system during which no unauthorized access existed; and determining that a possible unauthorized physical access exists if the reference pattern does not match the sampled pattern.

A method for the secured storing of a data element of a predefined data type to be stored by a computer program in an external memory, which is connected to a microcontroller, an error correction value of one error correction value data type being used. The method includes, when creating the computer program: defining a composite data element that includes one element of the data type and one element of the error correction value data type, in the computer program; and when executing the computer program: calculating the error correction value for the data element to be stored; forming an error correction data element as the composite data element, which contains the data element to be stored and the associated error correction value, which has been calculated for the data element; and writing the error correction data element to a memory address for the error correction data element.
