[0049] figure 1 is a schematic diagram showing a transmission mechanism 10 forming a part of a hybrid vehicle power transmission device to which a control device according to an embodiment of the present invention is applied. like figure 1 As shown in , the transmission mechanism 10 includes: an input shaft 14 serving as an input rotating member; a differential portion directly connected to the input shaft 14 or indirectly connected to the input shaft 14 through a pulse absorbing damper (vibration damper) not shown. 11. The automatic transmission part 20, which passes through the differential mechanism 11 and the driving wheels 38 via the power transmission member (power transmission shaft) 18 (see Figure 6 ) is connected in series to serve as a stepped transmission; and an output shaft 22 connected to the automatic transmission portion 20 as an output rotary member. All of these components are arranged in a transmission case 12 (hereinafter simply referred to as "case 12")...

Abstract

The invention relates to a control device for a hybrid vehicle power transmitting apparatus. A heat generation control is executed to increase a heat generation amount of an electric motor M1 when a differential portion 11 is placed in a non-differential state and a temperature of a shifting mechanism 10 is less than a given transmitting apparatus temperature determining value TEMP11. This allows the first electric motor M1 to develop a heat with which the temperature of a shifting mechanism 10 is promptly raised, thereby promptly completing a warm-up of the shifting mechanism 10 to achieve improved fuel consumption.

Description

technical field [0001] The present invention relates to a control device for a hybrid vehicle power transmission device used in a hybrid vehicle having an internal combustion engine and an electric motor. More specifically, it relates to a technique for promoting warm-up of a power transmission device of a hybrid vehicle. Background technique [0002] A known hybrid vehicle power transmission device includes a differential mechanism for distributing an output of an engine such as an internal combustion engine to a power transmission path between a first electric motor and drive wheels, a differential mechanism for limiting or canceling the differential action of the differential mechanism action limiting means, and a second electric motor connected to a power transmission means extending from the differential mechanism to the drive wheels. For example, Patent Document 1 (Japanese Patent Application Laid-Open No. 2006-46386) in figure 1 Such a hybrid vehicle power transmiss...
