Abstract
Official abstract text for this publication.
A running control device of a vehicle includes an engine with cylinders, a clutch connecting/disconnecting a power transmission path between the engine and wheels, and a variable mechanism to vary an intake air amount sucked into the cylinders. The running control device performs a normal running mode by transmitting engine drive force to the wheels, a neutral inertia running mode by disconnecting the power transmission path between the engine and the wheels, and a cylinder resting inertia running mode by resting at least a part of the cylinders while the power transmission path between the engine and the wheels is connected. The running control device makes the intake air amount sucked into the cylinders larger at the time of return from the neutral inertia running mode to the normal running mode as compared to the case of return from the cylinder resting inertia running mode to the normal running mode.
First claim
Opening claim text (preview).
The invention claimed is: 1. A running control device of a vehicle including an engine with a plurality of cylinders, a clutch connecting/disconnecting a power transmission path between the engine and wheels, and a variable mechanism being configured to vary an intake air amount sucked into the cylinders of the engine, the running control device of a vehicle configured to perform: a normal running mode performed by transmitting a drive force of the engine to the wheels, a neutral inertia running mode performed by disconnecting the power transmission path between the engine and the wheels, and a cylinder resting inertia running mode performed by resting at least a part of the cylinders of the engine while the power transmission path between the engine and the wheels is connected, the running control device of the vehicle configured to make the intake air amount sucked into the cylinders larger at a time of return from the neutral inertia running mode to the normal running mode as compared to a case of return from the cylinder resting inertia running mode to the normal running mode. 2. The running control device of a vehicle of claim 1 , wherein the variable mechanism is a variable valve mechanism configured to change at least one of valve-opening timing, a lift amount, and a working angle of an intake valve of the engine. 3. The running control device of a vehicle of claim 1 , wherein the neutral inertia running mode is performed with the engine put in idle operation or with fuel supply to the engine stopped.
