摘要： The invention relates to a system for providing fault tolerance for at least one micro controller unit, hereinafter called MCU (10). The MCU receives information from at least one sensor (11) coupled to the MCU (10) and outputs information to at least one actuator (12) coupled to the MCU (10). To provide a system for controlling or influencing the fault tolerance or the error processing of at least one MCU without requiring a replication of software or hardware components and which is able to react differently on various events it is proposed to include a System Supervision unit (200), hereinafter called SSU (200), in the MCU (10). The SSU (200) reacts on error reports included in information (301, 302, 303, 325) received at the SSU (200); wherein the SSU (200) is adapted to switch into one of a plurality of predetermined states based on the information (301, 302, 303) received and based on a state history of the MCU (10); and to output at least one instruction to the MCU (10) or to an external control device (230) coupled to the MCU (10) to control at least the MCU (10) and/or the connected devices (11, 12) based on the new state into which the SSU is switched. Such system could be easily adapted to the respective application.
