Beschreibung
Zusammenfassung:	A vehicle drive control apparatus includes an engine (12) that generates power through combustion of fuel, an automatic transmission (10) that transmits a reverse input from a driving wheel to the engine and automatically performs a gear shifting among a plurality of forward gear stages each having a different gear ratio, and a controller (90) that executes a fuel cut control (104) for stopping supply of the fuel to the engine upon establishment of a fuel cut condition including that a vehicle is in a coasting state where a throttle valve of the engine is fully closed, and an engine speed is equal to or higher than a predetermined value. The controller executes a control (114) of the automatic transmission for downshifting at a predetermined coast down vehicle speed so as to continue the fuel cut control in the coasting state, and temporarily expands an air passage (106) in an intake side of the engine while continuing execution of the fuel cut control during the downshifting.
