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

Provided is a vehicle drive system equipped with: an engine; a manual transmission capable of changing the gear range; a clutch arranged between the engine and the transmission; and a control device that controls the driving of the engine. During coasting, when the transmission of torque between the engine and the axle is interrupted, the control device cuts the fuel to the engine when the clutch is released, and the gear range of the transmission is changed to an ahead stage and the gear range after this change is lower than the optimal gear range corresponding to the vehicle speed.

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...
