Vehicle drive control apparatus and method |
摘要 |
<p>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, a fluid power transmission device (14) interposed between the automatic transmission and the engine for transmitting power through fluid, the fluid power transmission device having a lock-up clutch, 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, and executes a control (120) for engaging the lock-up clutch upon establishment of a lock-up clutch engagement condition including that the vehicle is in the coasting state. 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 executes a feedback control (122) of an engagement torque of the lock-up clutch such that a slip amount of the lock-up clutch reaches a target slip amount upon execution of the control of the automatic transmission for downshifting.</p> |
