At this time, when the shift position selected by the driver is lower than the shift position that should be selected for the current vehicle speed (shift operation error), the engine may be subjected to the kinetic energy of the vehicle and cause an over-revving state.

Abstract

A vehicle drive system is provided with an engine, a manual transmission capable of changing a gear position, a clutch arranged between the engine and the transmission, and a control device that performs drive control of the engine. During an inertia running in which torque transmission between the engine and an axle is blocked, when the clutch is opened and the gear position of the transmission is changed to a forward position, if the gear position after the change is lower than an optimal gear position corresponding to a vehicle speed, the control device executes fuel cutoff for the engine.

Description

technical field [0001] The present invention relates to a drive system for a vehicle, and more particularly, to a drive system for a vehicle capable of suppressing the occurrence of an engine over-revving state caused by a shifting operation error when switching from inertial running to engine running. Background technique [0002] In recent years, in a drive system for a vehicle having an MT (Manual Transmission: manual transmission), fuel-saving control in which a fuel cut is executed and an engine is stopped during coasting has been adopted. Among them, when the driver switches from inertial driving to engine driving, he performs a shift from neutral to forward. At this time, if the shift position selected by the driver is lower than the shift position that should be selected for the current vehicle speed (shift operation error), the engine may be subjected to the kinetic energy of the vehicle and an over-revving state may occur. As a conventional vehicle drive system re...
