Official abstract text for this publication.
A running control device is configured to execute an engine coupling running mode performed with an engine and wheels connected by a connecting/disconnecting device, a neutral inertia running mode performed with the engine separated from the wheels by the connecting/disconnecting device while the engine is supplied with fuel and allowed to perform self-sustaining rotation, and a free-run inertia running mode performed with the engine separated from the wheels by the connecting/disconnecting device while fuel supply to the engine is stopped to stop rotation. The neutral inertia running mode is terminated when an operation amount of the accelerator pedal becomes equal to or greater than a predefined first determination value. The free-run inertia running mode is terminated when an operation amount of the accelerator pedal becomes equal to or greater than a predefined second determination value larger than the first determination value.
Opening claim text (preview).
The invention claimed is: 1. A running control device of a vehicle including an engine, an accelerator pedal, and a connecting/disconnecting device connecting/disconnecting the engine and wheels, the running control device of a vehicle being configured to execute an engine coupling running mode performed with the engine and the wheels connected by the connecting/disconnecting device, a neutral inertia running mode performed with the engine separated from the wheels by the connecting/disconnecting device while the engine is supplied with fuel and allowed to perform self-sustaining rotation, and a free-run inertia running mode performed with the engine separated from the wheels by the connecting/disconnecting device while fuel supply to the engine is stopped to stop rotation, the neutral inertia running mode being terminated when an operation amount of the accelerator pedal becomes equal to or greater than a predefined first determination value α while the neutral inertia running mode is performed, the free-run inertia running mode being terminated when an operation amount of the accelerator pedal becomes equal to or greater than a predefined second determination value β larger than the first determination value α while the free-run inertia running mode is performed. 2. The running control device of a vehicle of claim 1 , wherein a return to the engine coupling running mode is made when an operation amount of the accelerator pedal becomes equal to or greater than the first determination value α while the neutral inertia running mode is performed, and wherein a return to the engine coupling running mode is made when an operation amount of the accelerator pedal becomes equal to or greater than the second determination value β while the free-run inertia running mode is performed.
