Filed: 2002-03-28
Abstract: <P>PROBLEM TO BE SOLVED: To provide a fuel control device for a fuel gas vehicle capable of preventing an error determination on fuel leakage caused by a close failure of a container main valve.  <P>SOLUTION: When the close failure of either of the container main valves of two fuel vessels is detected, a determination value α is increased (step S150).

Accordingly, the error determination of presence of the fuel leakage due to the close failure of the container main valve can be prevented. As a result, an occurrence of situations such as giving an unneeded warning to a passenger lighting on a warning lamp owing to the error determination on the fuel leakage and unnecessarily halting the vehicle can be prevented.  <P>COPYRIGHT: (C)2004,JPO
