[0057] FIG. 1 is a schematic diagram explaining a transmission mechanism 10 constituting a part of a drive system for a hybrid vehicle controlled by a control device according to an embodiment of the present invention. The transmission mechanism 10 includes: an input rotating member in the form of an input shaft 14 arranged on a common shaft in a transmission housing 12 serving as a stationary member mounted to the vehicle body; directly or via a pulsation absorber not shown A damper (vibration damping device) indirectly connected to the continuously variable transmission portion 11 of the input shaft 14; a stepped or multi-stage automatic transmission portion 20, which is arranged between the continuously variable transmission portion 11 and the vehicle drive wheels 38 and passes through the power transmission member (power transmission shaft) 18 is connected in series to continuously variable transmission portion 11 and drive wheels 38 of the vehicle (shown in FIG. 5 ); The ...

[0116] Referring to the block diagram of FIG. 12 , there is shown a control device according to a second embodiment of the present invention, which is arranged to execute the switching shock reduction routine shown in the flowchart of FIG. 13 . Although the present control device according to the second embodiment is configured to control the drive system including the engine 8 and the transmission mechanism 10 shown in FIGS. , instead of the power source torque variation limiting control section 82 provided in the first embodiment.
[0117] The meshing end stage judging section 88 is configured to judge whether the switching clutch C0 or the switching brake B0 to be engaged to establish the stepped shift state is in the ending stage of its meshing action, which is judged by the switching control section 50 that the transmission mechanism 10 should start from It starts when the continuously variable shift state is switched to the stepped shift state. The end phase is defined ...

[0142] 15 is a schematic diagram showing the arrangement of the transmission mechanism 70 of the vehicle drive system according to the third embodiment of the present invention. The transmission mechanism 70 can be controlled by the electronic control device in the first or second embodiment. Although the variator mechanism 70 is different from the variator mechanism 10 according to the first embodiment of FIGS. 1-11, the variator mechanism 70 is composed of the electronic components described above for the first embodiment of FIGS. 1-11 or the second embodiment of FIGS. 12-14. The control device 40 is basically controlled by the same electronic control device. FIG. 16 is a table showing different combinations of the gear positions of the transmission mechanism 70 and the engagement states of the hydraulically operated friction coupling devices used to respectively establish these gear positions, and FIG. 17 is a collinear diagram for explaining the shift operation of the trans...
