摘要
Disclosed herein are a method and apparatus for restoring a mechanical relay from a stuck fault to a normal condition. The method may include detecting, by an MCU, a short state or open state of a relay, repeatedly transferring, by the MCU, a current application signal and a current non-application signal to a relay driver when the relay is in the short state, repeating, by the relay driver, an operation of periodically applying an electric current from a power source unit to the relay in response to the current application signal and the current non-application signal so that the release of the contact point of the relay is induced, detecting, by the MCU, the release state of the contact point of the relay, and maintaining, by the MCU, an ECU in an operating state when the contact point of the relay is released.
