Embodiment Construction

[0026]Embodiments of the control device will be described with reference to the drawings. The control device is a control device that controls the vehicle drive device. In this embodiment, the drive control device 30 (see figure 1 ) is equivalent to "control device".

[0027] In the following description, "drive connection" refers to a state in which two rotating members are connected so that a driving force can be transmitted. This concept includes a state in which two rotating members are connected to rotate integrally, and a state in which two rotating members are connected so that driving force can be transmitted via one or more transmission members. Such transmission components include various components (shafts, gear mechanisms, transmission belts, chains, etc.) that transmit rotation at the same speed or at variable speeds, and may also include engagement devices that selectively transmit rotation and driving force (friction engagement devices, mesh engagements, etc.)...

Abstract

The present invention realizes a control device capable of reducing the shock transmitted to the wheels due to the inversion of the direction of the required torque without shifting the timing for inverting the direction of the required torque transmitted to the wheels from the start timing of the internal combustion engine. The control device performs slip control during start control for starting the internal combustion engine (ENG). In slip control, when the accelerator opening degree is decreased in a state where the rotation speed of the rotation electric machine (MG) is higher than the synchronous rotation speed, the rotation speed of the rotation electric machine (MG) is maintained at a rotation speed higher than the synchronous rotation speed .

Description

technical field [0001] The present invention relates to a control device for controlling a vehicle drive device in which a first engagement device, a rotating electrical machine, and a second engagement device are provided in order from the internal combustion engine side on a power transmission path connecting an internal combustion engine and wheels. Background technique [0002] As a control device as described above, a device described in JP 2013-47062 A (Patent Document 1) is known. Patent Document 1 describes a technique for reducing the shock when the direction of the torque transmitted to the wheels is reversed in a state where only the torque of the rotating electric machine is transmitted to the wheels to drive the vehicle. Specifically, in a configuration in which the internal combustion engine is started on the condition that the running power required by the vehicle is equal to or greater than a threshold value, the threshold value is set larger than the optimum...
