Abstract
Official abstract text for this publication.
If the pressure in a supply passage drops at a speed greater than a first determination speed in a state in which a first mode for supplying gas fuel to an internal combustion engine is selected, a control apparatus inhibits selection of the first mode. Then, the control apparatus switches from the first mode to a second mode, in energy other than gas fuel is used. In this state, if the pressure in the supply passage drops at a speed greater than a second determination speed, the control apparatus maintains the state in which the second mode is selected. If the pressure in the supply passage drops at a speed lower than the second determination speed, the control apparatus cancels the inhibition of selection of the first mode when it is detected that a manual on-off valve is opened.
First claim
Opening claim text (preview).
The invention claimed is: 1. A vehicle control apparatus that is applicable to a vehicle having a first mode, in which only gas fuel is supplied to an internal combustion engine to drive the vehicle, and a second mode, in which the vehicle is driven by energy other than gas fuel, wherein the vehicle control apparatus is configured, when the first mode is selected, to supply gas fuel to the engine a supply passage for gas fuel, in which a manual on-off valve and a shutoff valve are…
