REMOTE STARTING DEVICE AND REMOTE STARTING METHOD

A remote starting device starts up an engine when receiving an RF signal instructing to start up the engine from a remote control terminal. A first switch is provided in parallel to an accessory switch which is disposed in a first power supply line connecting a battery to an electrical device for controlling accessories. A second switch is provided in parallel to an ignition switch which is disposed in a second power supply line connecting the battery to an electrical device for controlling non-accessories. A first controller controls the second switch to be turned on when starting up the engine. A first detector detects an insertion state of a key into a key cylinder by a user. A second detector detects an electrical connection state in the first power supply line. A second controller controls the first switch to be turned off when the first detector detects that the key is inserted in a state where the engine is started up. A third controller controls the second switch to be turned off when the second detector detects that the electrical connection state of the first power supply line is changed from an electrically-connected state to an electrically-disconnected state in a state where the first switch is turned off by the second controller.
