<P>PROBLEM TO BE SOLVED: To provide a control device of a drive device for hybrid vehicle that greatly improves fuel consumption without missing the opportunity of regenerative power generation and can end two operations in a shorter time than before by simultaneous control of upshift speed change operation of a transmission and release operation of a clutch. <P>SOLUTION: When an upshift speed change determination Us and a clutch engagement command Cc are continuously generated in a priority decision time Tf, two operations are simultaneously controlled, and a release side frictional engagement element is released (release pressure PA is decompressed by t2-t4). When the release side frictional engagement element becomes a release state, the front clutch is made a release state from the engagement state (t4), and when the front clutch becomes a release state, the generator motor is made to perform the regenerative power regeneration so that the motor rotation speed Nm becomes equal to the next gear change speed input shaft rotation speed Ni2 (generation of regenerative toque Tm1 by t4-t5), and when the motor rotation speed Nm and the next gear change speed input shaft rotation speed Ni2 become a predetermined relation, the engagement side frictional engagement element are engaged (rising of engagement pressure PB by t5-t6). <P>COPYRIGHT: (C)2013,JPO&INPIT |
