Abstract

A hybrid vehicle is provided in which in the neutral range or the parking range, power can be generated in a first power generation mode by engaging an odd-numbered position clutch so as to transmit a driving force of an engine to a motor/generator via a first input shaft, and power can be generated in a second power generation mode by engaging an even-numbered position clutch so as to transmit the driving force of the engine to the motor/generator via reversing means and the first input shaft. Therefore, according to the status of the odd-numbered position clutch and the even-numbered position clutch, by engaging either one thereof, it becomes possible to generate power in the first power generation mode or the second power generation mode, thus enabling power to be supplied without interruption.

Claims

1. A hybrid vehicle comprising

an engine,

a first input shaft to which a driving force of the engine is transmitted via a first clutch,

a motor/generator that is connected to the first input shaft,

a second input shaft that is disposed in parallel to the first input shaft and to which the driving force of the engine is transmitted via a second clutch,

an output shaft that is disposed in parallel to the first input shaft,

a first power transmission path that transmits rotation of the first input shaft to the output shaft via a first gear group and a first engagement element,

a second power transmission path that transmits rotation of the second input shaft to the output shaft via a second gear group and a second engagement element,

reversing means that reverses rotation of the engine transmitted thereto via the second clutch and transmits the rotation to the first input shaft via a reverse engagement element,

a third power transmission path that transmits rotation of the engine to the output shaft via the reversing means and the first power transmission path,

the hybrid vehicle establishing a forward gear position in a drive range through the first engagement element of the first power transmission path or the second engagement element of the second power transmission path and establishing a reverse gear position in a reverse range through the reverse engagement element of the third power transmission path and the first engagement element, wherein

in a neutral range or a parking range, it is possible to switch between a first power generation mode in which the first clutch is engaged so as to transmit the driving force of the engine to the motor/generator and generate power and a second power generation mode in which the second clutch is engaged so as to transmit the driving force of the engine to the motor/generator via the reversing means and generate power, and

the reverse engagement element is engaged in the neutral range or the parking range.

2. The hybrid vehicle according to claim 1, wherein when the first clutch fails, power is generated in the second power generation mode.
