Method for efficiently securing the safety-critical functions of a control device and control device

摘要

The method involves determining output data (7) for checking the output data with output data contained in a group without all original data. The output data are used only when confirmed by a check. Determination of the output data is performed using identical hardware and using an algorithm or a redundant hardware component i.e. processor, for determining the output data. A check value, a cyclic redundancy check (CRC) process and an ECC process are used for checking data integrity. Safety-critical output data are used as the output data. An independent claim is also included for a controller.
