METHOD AND APPARATUS FOR CONTROLLING WATCHDOG

摘要

A method of controlling a watchdog and an apparatus for the same are provided. The method of controlling a watchdog within a controller includes determining, by a processor, whether to respond to a fault in the controller by comparing a watchdog count with a predetermined watchdog warning level when the fault is detected. Further, the method includes storing, by the processor, information regarding a program group related to the detected fault and a watchdog reset count that corresponds to the program group within a memory after increasing the watchdog reset count when the fault is to be responded to. In addition the processor is configured to reset the controller when the watchdog count exceeds a predetermined watchdog timeout level. Therefore, the present invention prevents occurrence of repeated resets that result from the same cause within the controller.
