<p>Computer and function architecture for operating an electrical power steering mechanism characterised in that a control path (202) and a monitoring path (203) designed redundantly thereto are processed more or less in parallel on two assigned cores (Core1 Core2) of a redundant microcomputer (200) and computation differences within the control path (202) or the monitoring path (203) are detected at functional level by means of a comparator (204) and the results of individual calculation steps at granular level are detected by means of a core comparator (205) and upon a detected difference of the comparator (204) at functional level if the core comparator (205) has not diagnosed a computation error passes to emergency operation (206) in order to provide the further availability of at least one part of the steering support or the steering function for at least a certain period of time.</p> |
