Abstract
In a relay operation state maintaining device configured to maintain an operation state of a relay when an abnormality occurs in a controller configured to control an operation of the relay, the relay operation state maintaining device includes: a memory configured to store a relay control signal output for an operation of the relay by the controller at a time the abnormality occurs and to generate and output a memory output signal based on a stored signal; a first relay driving signal generator configured to generate and output a first relay driving signal based on the relay control signal and a signal corresponding to the abnormality occurrence; and a second relay driving signal generator configured to generate and output a second relay driving signal based on the first relay driving signal and the memory output signal.
