PROBLEM TO BE SOLVED: To improve fuel economy more than before by maximally accurately controlling regeneration torque at a gear change operation while suppressing the size-enlargement and cost increase of an automatic transmission.SOLUTION: In a control device 1 which controls a drive unit 9 for a hybrid vehicle, as a control object, having an engine 2, an automatic transmission 5, and a motor 4, the control device has: a hydraulic pressure indication part which indicates the first and second indication hydraulic pressure P1d, P2d of first and second friction elements which are connected and disconnected in a period in which an automatic transmission performs a shift-down gear change operation; an actual hydraulic pressure calculation part which calculates first and second actual hydraulic pressure equivalent values P1r, P2r by applying prescribed delay calculation processing to the first and second indication hydraulic pressure; a torque capacity calculation part which calculates first and second torque capacities Ta1, Ta2 on the basis of the first and second actual hydraulic pressure equivalent values; a regenerative torque calculation part which calculates regenerative torque TA on the basis of the first and second torque capacities; and a regeneration torque setting part which sets actual regeneration torque TQ within a range of the regenerative torque.SELECTED DRAWING: Figure 5 |
