<P>PROBLEM TO BE SOLVED: To perform change-over from a system for calculating target torque of an input side motor/generator by rotational frequency feedback control to a system for calculating target torque of an output side motor/generator by rotational frequency feedback control without generating shock. <P>SOLUTION: In a determination part 36, a flag FLAG<SB>MG</SB>is made to be 1 when a rotation difference (Ne-No) between an engine rotational frequency Ne and a transmission output rotational frequency No is equal to or more than a set value Na* and a rotation difference (tNm2-Nm2) between an output side motor/generator target rotational frequency tMn2 and an actual rotational frequency Nm2 is equal to or more than 0, and the flag FLAG<SB>MG</SB>is made to be 0 when the rotation differences are other than the values. When the flag FLAG<SB>MG</SB>is 0, the input side motor/generator target torque tTm1 is calculated with an calculator 51 by frequency control feedback control, and the output side motor/generator target torque tTm2 is calculated with an calculator 54 by power balance. When the flag FLAG<SB>MG</SB>is 1, a calculation system is changed over so that tTm1 is calculated with a calculator 53 by power balance and tTm2 is calculated with a calculator 52 by rotational frequency feedback control. The system is changed over when the difference between tNm2 and Nm2 (tNm2-Nm2) is equal to or more than 0, and thereby tTm 2 does not become minus and the deceleration shock can be avoided. <P>COPYRIGHT: (C)2004,JPO |
