POWER TRANSMISSION MECHANISM FOR HYBRID VEHICLE
First Claim
1. A power transmission mechanism for hybrid vehicle, the power transmission mechanism comprising:
- an internal combustion engine for outputting a power;
a generator motor for carrying out electric power generation when a power is inputted, and outputting a power when not generating an electric power;
a controller for selecting and then controlling the internal combustion engine and the generator motor as a driving source for running;
a power interrupter for connecting the generator motor with a power transmission route for transmitting the power and then disconnecting the generator motor from the power transmission route, or vice versa, intermittently; and
the controller controlling the power interrupter wherein the power interrupter is activated and then deactivated, or vice versa, intermittently, with reference to at least one piece of information being selected from the group consisting of information on road conditions, information on traffic conditions and information on vehicular conditions.

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.

8. A method of controlling hybrid vehicle, the method comprising the steps of:
-
retrieving a vehicular speed of a hybrid vehicle; comparing the vehicular speed with a first predetermined speed specifying that the hybrid vehicle is creeping, wherein a power transmission mechanism is activated to connect a generator motor with a power transmission route if the vehicular speed is less than the first predetermined speed; retrieving a charged voltage of a battery that the hybrid vehicle has on board if the vehicular speed is equal to or faster than the first predetermined speed; comparing the charged voltage with a first predetermined voltage specifying that the battery is charged insufficiently, wherein the power transmission mechanism is activated to connect the generator motor with the power transmission route if the charged voltage is equal to or less than the first predetermined voltage; comparing the charged voltage with a second predetermined voltage specifying that the battery is overcharged, wherein the power transmission mechanism is deactivated to disconnect the generator motor from the power transmission route if the charged voltage is equal to or greater than the second predetermined voltage; retrieving information on road conditions if the charged voltage is less than the second predetermined voltage; judging whether or not an ordinary running requirement is met, wherein the power transmission mechanism is activated to connect the generator motor with the power transmission route if the ordinary running requirement is not met; retrieving information on traffic conditions if the ordinary running requirement is met; judging whether or not it is possible to run the hybrid vehicle ordinarily, wherein the power transmission mechanism is activated to connect the generator motor with the power transmission route if it is not possible to do so; comparing the vehicular speed with a second predetermined speed specifying that the hybrid vehicle is running ordinarily, wherein the power transmission mechanism is activated to connect the generator motor with the power transmission route if the vehicular speed is slower than the second predetermined speed, or the power transmission mechanism is deactivated to disconnect the generator motor from the power transmission route if the vehicular speed is equal to or faster than the second predetermined speed.
