Abstract
Official abstract text for this publication.
A running control device of a vehicle includes an engine, a clutch separating the engine and wheels, and a torque converter with a lockup clutch transmitting power of the engine toward the wheels, the running control device of a vehicle is configured to execute a neutral inertia running mode that is an inertia running mode performed while the engine and the wheels are separated and a cylinder resting inertia running mode performed by stopping operation in at least some of cylinders of the engine while the engine and the wheels are coupled, the lockup clutch has a weak engagement force while the neutral inertia running mode is performed as compared to while the cylinder resting inertia running mode is performed.
First claim
Opening claim text (preview).
The invention claimed is: 1. A running control device of a vehicle including an engine, a clutch separating the engine and wheels, and a torque converter with a lockup clutch transmitting power of the engine toward the wheels, the running control device of a vehicle being configured to execute a neutral inertia running mode that is an inertia running mode performed while the engine and the wheels are separated and a cylinder resting inertia running mode performed by stopping operation in at least some of cylinders of the engine while the engine and the wheels are coupled, the lockup clutch having a weaker engagement force while the neutral inertia running mode is performed as compared to while the cylinder resting inertia running mode is performed. 2. The running control device of a vehicle of claim 1 , wherein the lockup clutch is released while the neutral inertia running is performed, and wherein the lockup clutch is engaged while the cylinder resting inertia running is performed. 3. The running control device of a vehicle of claim 1 , wherein the cylinder resting inertia running is inertia running performed by stopping fuel supply to the engine while the engine and the wheels are coupled and by stopping operation of at least one of pistons and intake/exhaust valves of at least some of the cylinders of the engine. 4. The running control device of a vehicle of claim 1 , wherein the neutral inertia running is inertia running performed with fuel supply to the engine stopped to stop rotation, or inertia running performed with the engine supplied with fuel and operated, while the engine and the wheels are separated.
