摘要:
A gear box (9) for a vehicle having at least two driving wheels (10) each driven by a traction chain (8, 12, 9, 11) including an electric machine (12) driving a primary shaft (8), the electric machine (12) being mechanically connected to the primary shaft (8), a wheel (10) being driven by a secondary shaft (11), a gear change including a counter-rotation phase followed by a jaw clutching phase in which a sleeve (21) connected to the shaft (8, 11) meshes in the receiving clutch sleeves (41) connected to the other shaft (8, 11), wherein during the jaw clutching phase, the electric machine (12) is controlled for imparting to the primary shaft a torque that generates a rotation in a direction opposite to the rotation movement due to the ratio change.

Implemented is a control device capable of securing a desired amount of electric power while suppressing the amount of heat generation of a second engagement device, in a specific traveling state such as when a vehicle is made to travel at a low vehicle speed. The control device controls a vehicle drive device in which a first engagement device, a rotating electrical machine, a second engagement device, and an output member are sequentially arranged in this order from an input member side on a power transmission path that connects the input member drivingly coupled to an internal combustion engine to the output member drivingly coupled to wheels. The control device controls both the first engagement device and the second engagement device to a slip engaged state, and causes the rotating electrical machine to generate electric power.

In a hybrid drive device, an input shaft is connected to an engine, an output shaft is connected to wheels, and a wheel drive motor is connected between the input shaft and the output shaft. The hybrid drive device includes: a friction engagement element that is provided between the input shaft and the output shaft and of which transfer torque is controllable; and a control device that controls the friction engagement element. The control device reduces the transfer torque of the friction engagement element under a predetermined condition.

摘要:
In an on-vehicle hybrid drive apparatus including a power-transmission shaft (22) transmitting rotation generated from an engine (3) into a transmission (4), and a motor-and-generator (7) fitted on the power-transmission shaft (6) and installed between the engine (3) and the transmission (4), a first friction element (8) is installed on the engine side for coupling the engine (3) with or uncoupling it from the motor-and-generator (7). A second friction element (9) is installed on the transmission side for coupling the motor-and-generator (7) with or uncoupling it from a transmission output shaft (12). A rotating damper (24) is installed downstream of the motor-and-generator (7) and disposed in a rotating-motion transmission system ranging from the motor-and-generator (7) to the transmission output shaft (12). The rotating damper (24) is preferably interleaved in a coaxially abutted shaft portion of a central motor-and-generator shaft (22) and a transmission input shaft (5).
