DRIVING APPARATUS, CONTROL METHOD OF DRIVING APPARATUS, AND MOTOR VEHICLE EQUIPPED WITH DRIVING APPARATUS

摘要

Upon the setting of a gearshift position SP to a drivable gear position, for example, a drive position for general forward drive or a braking position for applying brake on downslope, when an engine rotation speed Ne decreases to or below a preset fuel injection-start reference rotation speed Nref1, a driving apparatus of the invention allows preliminary fuel injection before a stop of an engine into a specific cylinder that stops in a preset fuel injection stop range over an intake stroke to a compression stroke on the stop of the engine (steps S140 and S150). Upon the setting of the gearshift position SP to a non-drivable gear position, for example, a parking position for parking lock or a neutral position for keeping the gear neutral, on the other hand, the driving apparatus of the invention prohibits the preliminary fuel injection into the specific cylinder that stops in the fuel injection stop range on the stop of the engine (steps S140 and S190). This arrangement ensures a quick restart of the engine and effectively avoids potential troubles caused by non-combustion of the preliminarily injected fuel under a stop of the engine over a relatively long time.
