[0035] will refer to figure 1 and figure 2 One of the modes of execution of the present invention is described. For the power transmission device 1 of the hybrid vehicle according to the first embodiment of the present invention figure 1 The block diagram is shown. In the figures, arrows marked with solid lines represent power or energy flow, while arrows marked with dashed lines represent information or control flow. The power transmission apparatus 1 according to the first embodiment includes an internal combustion engine 2 , a generator motor 3 , a power interrupter 4 , a transmission device 5 and a hybrid ECU 6 .

[0036] The internal combustion engine 2 is a drive source for operating the hybrid vehicle, and outputs power from a crankshaft. The output power is input to the transmission device 5 through a clutch (not shown). The engine motor 3 has an output shaft coupled to a power transmission line through a power interrupter 4 . The engine motor 3 is connected to ...

Abstract

A power switcher mechanism includes an internal combustion engine, a generator motor, a controller and a power interrupter. The internal combustion engine outputs a power. The generator motor carries out electric power generation as well as outputs a power when a power is input. The controller selects and then controls the internal combustion engine and the generator motor as a driving source for running. The power interrupter connects the generator motor with a power transmission route for transmitting the power and then disconnects the generator motor from the power transmission route, or vice versa, intermittently. The controller activates the power interrupter and then deactivates it, or vice versa, intermittently, with reference to information on road conditions, information on traffic conditions or information on vehicular conditions.

Description

[0001] cross reference [0002] The present application is based on Japanese Patent Application No. 2009-262,841 filed on Nov. 18, 2009, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to a power transmission device for a hybrid vehicle having an internal combustion engine and a generator motor on the vehicle, the internal combustion engine and the generator motor being used as drive sources, respectively. Background technique [0004] Hybrid vehicles have entered practical applications. A hybrid vehicle has a dual drive source, ie, an internal combustion engine and a generator motor, and the hybrid vehicle intends to make use of the advantages of each of the internal combustion engine and the generator motor to realize improved fuel consumption, high output, and environmental protection. In such a hybrid vehicle, it is important to selectively control the drive source so that the generator motor driv...
