1. An ignition control method for controlling an operation of a passive safety device for a vehicle, the method comprising:

  • providing a passive safety device including a high-response safety device which requires a relatively short time to determine a request of operation and a low-response safety device which requires a relatively long time to determine a request of operation;

    detecting a predetermined state in which a request of operation to the low-response safety device is expected to occur; and

    determining an establishment of a condition for shifting operation of the passive safety device from a normal mode to a low-power-consumption mode when at least one of a first condition that a predetermined time has elapsed after power supply is shut off and a second condition that the predetermined state is detected in said detecting step is established.
