Embodiment Construction

[0037] Various embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0038]

[0039] figure 1 It is a perspective view showing a shift mechanism 10 constituting a part of a drive apparatus for a hybrid vehicle to which a control device according to an embodiment of the present invention is applied. Such as figure 1 As shown, the shift mechanism 10 includes: an input shaft 14 as an input rotary element; a differential portion 11, which is directly connected to the input shaft 14 or indirectly connected thereto through a pulsation absorbing damper (vibration damping device) not shown. On: the automatic shift part 20, which passes through the power transmission element (transmission shaft) 18 and the differential mechanism 11 and the drive wheel 38 (see Figure 6 ) between the power transmission path is connected in series as a step change type transmission; the output shaft 22, which is connected to the automati...

Abstract

This invention relates to a control device for a vehicular power transmitting device. The control device has shifting-point altering means 108 operative such that when a second electric motor M2 is operated with priority to obtain a charging efficiency and / or electric power generating efficiency, a shifting point for a vehicle to run under a decelerating state (during a coast running state) is altered to a point on a higher vehicle speed than that at which a shifting point for a running-performance-conscious state is set. Therefore, when the second electric motor M2 is operated with priority for generating electric power, a downshift is initiated at a high vehicle speed than that at which the downshift is initiated at a shifting point for a running-performance-conscious state. This increases a rotation speed NM2 of the second electric motor M2, resulting in an increase in regeneration amount (electric power generation amount) of the second electric motor M2.

Description

technical field [0001] The present invention relates to a control device for a vehicular power transmission device having a shift portion constituting part of a power transmission path between a driving force source and drive wheels, and an electric motor connected to the power transmission path. In particular, the present invention relates to a technology that performs regeneration control for a coast running mode so as to compatibly realize increased regeneration amount and drivability. Background technique [0002] There is known a control device for a vehicle power transmission device comprising: a shift portion constituting a portion of a power transmission path between a driving force source and drive wheels; an electric motor connected to the shift portion; enter. For example, Patent Document 1 (Japanese Patent Laid-Open No. 2006-2913) discloses such a hybrid vehicle power transmission device. With the control device disclosed in Patent Document 1, the differential ...
