Abstract: PROBLEM TO BE SOLVED: To perform high quality retreat travel in the event of a failure of a motor generator for inputting/outputting power with a drive shaft. SOLUTION: A hybrid vehicle 10 includes a dog clutch 360 on an output shaft 320 of a power dividing mechanism 300, and is composed such that either a motor generator MG2 or a motor generator MG3 is selectively connected to the output shaft 320. The power dividing mechanism 300 includes a variable transmission mode and a fixed transmission mode as a transmission mode. The MG3 is connected to the output shaft 320 in the fixed transmission mode, and the MG2 is connected to the output shaft 320 in the variable transmission mode. Therefore, the MG3 is composed such that its generation efficiency is higher than that of the MG2 in the operation condition of the output shaft 320 corresponding to the fixed transmission mode. In the retreat travel control when the MG2 is in a failed state, an ECU 100 controls the dog clutch 360 such that the MG3 is connected to the output shaft 320 even in the variable transmission mode.

Abstract: PROBLEM TO BE SOLVED: To provide a controller for a hybrid vehicle capable of securing travel performance responding at a high level, in either case of laying stress on a mileage or of laying stress on drivability.
SOLUTION: This controller for the hybrid vehicle includes a control means such as an ECU. The control means changes a speed change ratio mode over in response to a position of a current driving operation point, on a map set with a continuously variable speed change ratio mode area and a fixed speed change ratio mode area, and defined by a target driving force and a vehicular speed. An overlapping area is set between the continuously variable speed change ratio mode area and the fixed speed change ratio mode area, to prohibit the change-over of the speed change ratio mode. The control means widens the overlapping area, when laying stress on the drivability, compared with that when laying stress on the mileage. The travel performance responding at the high level is secured by this manner, in either case of laying stress on the mileage or of laying stress on the drivability.

Abstract: PROBLEM TO BE SOLVED: To accurately detect engine torque and brake part torque even in the fixed gear ratio mode of a transmission having a continuously variable speed mode and the fixed gear ratio mode. SOLUTION: A dog clutch mechanism includes a rotary element and a fixed element engaging each other. The rotary element includes a plurality of rotary side dog teeth, and the fixed element includes the same number of fixed side dog teeth. On at least one of the fixed side dog teeth, a pair of pressure detecting parts are provided at both ends contacting the rotary side dog teeth. The pressure detecting parts detect pressure given by the rotary side dog teeth in the state that the rotary side dog teeth gear with the fixed side dog teeth. In accordance with a difference between detected pressure values and the number of the dog teeth, torque on the fixed element can be calculated. COPYRIGHT: (C)2009,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a controller for a hybrid vehicle capable of enhancing the efficiency of power generation if there is a request for power generation. SOLUTION: The controller is provided for a hybrid vehicle having a power distribution device where an input element and a reaction element are connected to a drive source and generators, respectively to permit power transmission and an output element is connected to wheels via drive shafts to permit power transmission. The controller is capable of switching between a stepless variable speed mode in which rotation speed ratio between the drive source and the drive shafts is steplessly varied and a fixed variable speed mode in which rotation speed ratio is fixed. A first and a second generator are provided as the generators, the second generator having higher efficiency of power generation than the first generator. The controller has a power generation control means (step S9 to S14) which generates power using the second generator when the fixed variable speed mode is selected as a mode for controlling the rotation speed ratio and when there is a request for power generation.
