Abstract:
A method for error detection for at least one image processing system for capturing the surroundings of a motor vehicle, comprising the following steps: a) capturing at least one first primary image (PB1), b) producing at least one first reference image (RB1) by introducing at least one reference feature (RM) into the at least one first primary image (PB1), c) processing the at least one first reference image (RB1) with the aid of at least one algorithm to be checked, d) extracting at least one test feature (TM) associated with the at least one reference feature (RM) from the processed at least one first reference image (RB1), e) comparing the at least one test feature (TM) with the at least one reference feature (RM) and using the result of the comparison in order to determine the presence of at least one error.
Abstract:

Abstract:
A method for monitoring the short-circuiting switching device of a three-phase motor (3) for driving vehicles, which is fed from a DC voltage source (1) via a controlled converter (2), wherein the short-circuiting switching device (5) actuated by a control logic (6) is connected to the inputs of the motor, and the motor currents and/or motor voltages are measured, and a predetermined test pattern, which is different from the voltage/current profiles during operation, is generated with the aid of the controlled converter (2) during a test phase and is supplied to the motor (3), the short-circuiting switching device is actuated for the activation thereof, the current and/or voltage profile is detected during the test phase by opening and closing of short-circuiting contacts and, on the basis of the current and/or voltage distribution in the individual motor phases, the correct open-ing/closing of the short-circuiting contacts is detected and evaluated.
Abstract:
A method is provided by which a complex electronic system for controlling a safety-critical technical process, for example driving an autonomous vehicle, can be implemented. A distinction is made between simple and complex software, wherein the simple software is executed on error-tolerant hardware and wherein a plurality of diverse versions of the complex software are implemented simultaneously on independent fault containment units (FCU). A consolidated environmental model is developed from a number of different environmental models and represents the basis for trajectory planning.
Abstract:
An innovative method is provided by which a complex electronic system for controlling a safety-critical technical process, for example driving an autonomous vehicle, can be implemented. A decision is made between simple and complex software, wherein the simple software is implemented on error-tolerant hardware and wherein a plurality of different versions of the complex software are simultaneously implemented in independent fault containment units (FCU) and wherein a result that is to be transmitted to the actuators is selected by a decider from the results of the complex software that is implemented using the simple software.
