Embodiment Construction

[0044] Embodiments of the present invention will be described with reference to the drawings. In this embodiment, a case where the control device of the present invention is applied to a vehicle drive device 1 for a hybrid vehicle will be described as an example. figure 1 It is a schematic diagram showing the configuration of a drive transmission system and a hydraulic control system of the vehicle drive device 1 according to the present embodiment. In the figure, a solid line indicates a transmission path of driving force, a dotted line indicates a supply path of hydraulic oil, and a dotted line indicates a supply path of electric power. In addition, (P1) or (P2) arranged adjacent to the dotted line indicates that the oil pressure of the working oil in the supply path is the first oil pressure P1 or the second oil pressure P2. As shown in the figure, the vehicle drive device 1 according to the present embodiment generally has a structure including an engine 11 and a rotatin...

Abstract

A control apparatus includes a differential speed acquisition unit that acquires a differential speed representing a difference in speed between an input side drivingly connected to the input member of the fluid coupling and an output side drivingly connected to the transmission; a state determination unit that determines a shift speed in the transmission and an operating state of the direct connection clutch based on an accelerator opening and a vehicle speed of a vehicle; and a direct connection control unit that engages, if the differential speed is equal to or less than a predetermined engagement permitting threshold value when the state determination unit determines an upshift of the shift speed and a transition from a disengaged state to an engaged state of the direct connection clutch in a condition in which the accelerator opening is decreasing, the direct connection clutch regardless of an upshift operation of the shift speed.

Description

technical field [0001] The present invention relates to a control device for controlling a driving device for a vehicle, wherein the driving device for a vehicle includes a fluid coupling with a direct clutch and a speed change device for drivingly connecting an engine and a rotating electrical machine The rotation of the input member is output to the output member. Background technique [0002] In recent years, a hybrid vehicle has been put into practical use, which uses both an engine and a rotary electric machine as a driving force source, thereby enabling a reduction in the fuel consumption rate of the engine and reduction in exhaust emissions. As an example of a vehicle drive device used in such a hybrid vehicle, for example, Patent Document 1 below proposes a vehicle drive device including a fluid coupling having a direct clutch and a transmission. A device for outputting the rotation of an input member drivingly coupled to an engine and a rotating electric machine to...
