<P>PROBLEM TO BE SOLVED: To provide an in-vehicle electronic control device which can process a decompressing treatment of fuel tank without needing a new control device, and prevent fuel evaporating gas from diffusing from the fuel tank when a filler cap is opened. <P>SOLUTION: The vehicle electronic control device, wherein: a vehicle electronic control device 100A, energized through a power supply relay 102 energized by closing in circuit a power supply switch 103 when the vehicle is driven, is used together; the power supply relay 102 is energized when a filler lid opening command switch 104 is closed in circuit when the vehicle stops or when the power supply switch 103 is opened in circuit; a microprocessor 10 started in operation keeps an energization of the power supply relay 102 by generating a self-hold command output DR1, and opens the filler lid or a safety door after the decompressing treatment control within the fuel tank is performed; an opening of the filler cap and refueling operation are performed by manual operation; and the filler cap and filler lid are closed, or the self-hold command output DR1 is stopped after a predetermined time is passed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
