Embodiment Construction

[0014] Refer to the following Figure 1 to Figure 5 Embodiments of the present invention will be described. The vehicle drive device according to the embodiment of the present invention is applied to a hybrid vehicle including an engine and a motor generator as running drive sources. figure 1 It is an overall configuration diagram schematically showing the vehicle drive device 100 of the present embodiment.

[0015] like figure 1 As shown, the vehicle drive device 100 includes an engine (ENG) 1 as a drive source, first and second motor generators (MG1, MG2) 2, 3, and a differential mechanism 6 interposed between the drive source and the differential mechanism 6, The torque generated by the drive source is transmitted to the gear mechanism 10 of the left and right axles 4 via the differential mechanism (DF) 6 .

[0016] The vehicle drive device 100 has a plurality of rotation shafts parallel to the axle 4 . That is, it has a rotating shaft (output shaft) 11 extending along ...

Abstract

A vehicle drive device (100) is provided with: a first oil pump (35) driven by an internal combustion engine (1); a second oil pump (36) connected to a torque transmission unit (10) that transmits the driving force of the second motor generator (3) to a drive wheel; a hydraulic circuit (50) configured so as to supply lubricating oil from the second oil pump (36) to the lubrication unit (LP) when the travel mode is a first mode in which travel is performed while driving the internal combustion engine (1) is stopped, and so as to supply lubricating oil from the first and second oil pumps (35, 36) to the lubrication unit (LP) when the travel mode is a second mode in which travel is performed while driving the internal combustion engine (1); a slip detection unit that detects a slip state of the drive wheel; and a control unit (5) that switches the travel mode to the second mode when a slip state is detected when the travel mode is the first mode.

Description

technical field [0001] The present invention relates to a vehicle drive device for driving a vehicle. Background technique [0002] As such a device, a device having an engine, a first electric motor for power generation, and a second electric motor for running has been conventionally known, and the torque of the engine is transmitted to the axle through a first transmission path, and the torque of the engine is transmitted through a second transmission path. The torque of the second electric motor is transmitted to the axle. Such a device is described in Patent Document 1, for example. In the device described in Patent Document 1, the transmission path of torque is switched by switching the clutch, thereby realizing either engine running using the torque of the engine or motor running using the torque of the second electric motor. [0003] As described in Patent Document 1, an oil pump driven by rotation of an output shaft of the engine and an oil pump driven by rotation ...
