<p><P>PROBLEM TO BE SOLVED: To provide a device for controlling throttle inhibition in up-shift not causing a trouble such as racing of an engine and gear shift shock even if torque down of the engine is performed by closing a throttle in up-shift. <P>SOLUTION: Even if an electronic control throttle is closed for a predetermined period of time by throttle inhibition control and Ev value (intake air volumetric efficiency) gets below power ON/OFF judgment line during up-shift control under a power ON condition, gear shift control is performed according to gear shift control rule corresponding to power OFF when elapse time A or accelerator return quantity satisfys a predetermined condition without immediately making power OFF judgment. When AT input shaft torque can not follow fluctuation of Ev value and does not get below torque zero line, gear shift control according to gear shift rule corresponding to power OFF is not performed by mistake, and a trouble such as racing of the engine and gear shift shock does not occur. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
