Title:
車両の制御装置
Document Type and Number:
Japanese Patent JP4375276
Kind Code:
B2
Abstract:
A hybrid vehicle has, as its driving-force source, an internal combustion engine that includes an in-cylinder injector directly injecting fuel into a cylinder and an intake manifold injector injecting fuel into an intake manifold and/or an intake port as well as another driving-force source. When the internal combustion engine is operated in such an operation state as the low-vehicle-speed running state where the sound generated from the whole vehicle is low in volume, the fuel injection ratio between the injectors is set so that the total fuel quantity is injected by the intake manifold injector, without using the in-cylinder injector that injects fuel at a high pressure. In this way, the operating sound of the internal combustion engine can be reduced in the operation state where the sound generated from the whole vehicle is low in volume.
