<p><P>PROBLEM TO BE SOLVED: To evade put-ahead lock-up ON control from becoming inoperable, by an acceleration opening getting relatively high for obtaining acceleration equivalent to that of a vehicle under a standard state, when traveling resistance of the vehicle is higher than traveling resistance of the vehicle under the prescribed standard state. <P>SOLUTION: A value obtained by adding an excessive driving force Fs to the traveling resistance FRL1 calculated by a traveling resistance calculating means is set as an upper limit driving force threshold value Ftgt for permitting execution of the put-ahead lock-up ON control (ST7), when a vehicular speed V is less than a lock-up ON vehicular speed Vluon1, and a put-ahead lock-up ON permitting vehicular speed Vluon2 or more (ST3:YES), and when a change gear ratioγof a belt type continuously variable transmission is a prescribed valueγ1 or more (ST4:YES), and the put-ahead lock-up ON control is executed (ST9), when an actual driving force Fs calculated by an actual driving force calculating means is the upper limit driving force threshold value Ftgt or less (ST8;YES). <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
