CIRCUIT ARRANGEMENT AND METHOD FOR MONITORING A DSP IN THE CONTEXT OF A SECURITY CRITICAL APPLICATION

摘要

The invention relates to a circuit arrangement of a sensor-triggered control and/or display system in the context of a safety-critical application with a DSP and a method for monitoring the DSP, characterized-in-that the position and/or attitude signals transferred to the DSP are reduced in terms of their information content, the reduced information content is delivered to a position and attitude computation instance and checked as to whether the unambiguous position and/or attitude determined by the DSP agrees with the inaccurate and/or ambiguous position and/or attitude determined by the position and attitude computation circuit within the scope of the accuracy and/or ambiguity, and a sensor fault signal is output if the check is negative.
