Embodiment Construction

[0050] In the following description and drawings, the invention will be described in detail in terms of exemplary embodiments.

[0051] FIG. 1 is a schematic diagram of a transmission mechanism 10 constituting a part of a drive system of a hybrid vehicle to which the present invention is applicable. In FIG. 1 , a transmission mechanism 10 includes, in sequence (in series), an input shaft 14 , an electric differential portion (hereinafter simply referred to as “differential portion”) 11 , an automatic transmission portion 20 , and an output shaft 22 . The input shaft 14 is an input rotary member arranged on a common shaft inside the transmission case 12 , which is a non-rotational part mounted on a vehicle body (hereinafter, the transmission case 12 is simply referred to as "case 12"). The differential portion 11 is a continuously variable transmission portion connected either directly to the input shaft 14 or indirectly connected to the input shaft 14 through a pulsation absor...

Abstract

In a control apparatus of a vehicular drive system, a charging / discharging-restricted shift control apparatus makes a determination to perform a shift in a shifting portion such that less power is charged to a power storage device or discharged from a power storage device when charging or discharging of the power storage device is restricted than when charging or discharging of the power storage device is not restricted.

Description

technical field [0001] The present invention relates to a control device and a control method for a vehicle drive system equipped with: i) an electric differential portion having a differential mechanism capable of differential operation (differential action); and ii ) is provided in the transmission section in the power transmission path from the electric differential section to the drive wheels. More specifically, the present invention relates to a control device and a control method for a vehicle drive system when charging or discharging of a power storage device is restricted. Background technique [0002] A known control device for a vehicle drive system includes an electric differential portion and a transmission portion. The electric differential section includes a differential mechanism having three elements, namely, a first element connected to the engine, a second element connected to the first electric motor, and a third element connected to the transmission memb...
