Abstract:
La présente invention concerne un groupe motopropulseur de véhicule automobile de type hybride comportant une machine motrice/réceptrice (20), un moteur thermique (10), un dispositif de variation de vitesse (14) comprenant un train épicycloïdal de moteur (24) avec un planétaire (34), une couronne (44) reliés chacun à l'arbre de moteur (12) par un accouplement à commande contrôlée (26, 28) et à une partie fixe (42) du groupe par un accouplement unidirectionnel (30, 32) et un porte-satellites (48), un autre train épicycloïdal de machine (58) comprenant un planétaire (56), une couronne (66) et un porte-satellites (60) reliés à un dispositif de transmission de mouvement (79) à un essieu moteur (16), et une voie de transmission de mouvement de rotation pour la liaison entre ledit arbre de moteur et ledit dispositif de transmission de mouvement. La voie de transmission de mouvement (90, 124) comprend une liaison contrôlée (80, 94, 134) entre l'arbre de moteur (12) et au moins l'un des éléments (48, 56, 60, 66) de l'un des trains épicycloïdaux (24, 58).
Abstract:
A motorcycle (1) is disclosed wherein a crank shaft (56) is disposed in a lower portion of a power unit case (55), a clutch shaft (57) is disposed in parallel to and higher than the crank shaft (56), and a transmission shaft (58) and an electric motor shaft (59) are disposed in such a manner as to extend from one end of the clutch shaft (57) in a longitudinal (fore and aft) direction of the vehicular body. That is, the clutch shaft (57), transmission shaft (58), and electric motor shaft (59) are disposed in series and also in parallel to and higher than the crank shaft (56). Since the transmission shaft (58) and the electric motor shaft (59) are disposed in series in the longitudinal direction of a vehicular body, the direction of a force applied to the power unit case (55) becomes simple. This makes the designing of the power unit case easy.
Abstract:
A vehicle includes an engine (2), a rotary machine (MG2), at least one driving wheel (25), a first clutch (CL1) disposed between a power transmission path (11) and the rotary machine (MG2), the power transmission path (11) being defined between the engine (2) and the driving wheel (25) the first clutch (CL1) being switched to an engaged state or a disengaged state, a one-way clutch (CL2) disposed in parallel with the first clutch (CL1), an oil temperature detector (5) configured to detect a temperature of oil supplied to a power transmission part including the rotary machine (MG2), and an electronic control unit (40). The electronic control unit (40) is configured to limit an operating zone in which a predetermined traveling mode is allowed when the oil temperature detected by the oil temperature detector (5) is low compared to when the oil temperature is high, where the predetermined traveling mode is a traveling mode in which the vehicle travels with the rotation of the rotary machine (MG2) being stopped.
Abstract:
A vehicle includes an engine (2), a rotary machine (MG2), at least one driving wheel (25), a transmission member (11) arranged between the engine (2) and the driving wheel (25), a clutch (CL1) having a first engagement element (32) connected to the transmission member (11) and a second engagement element (33) connected to the rotary machine (MG2), the clutch (CL1) being configured to engage or disengage the first engagement element (32) and the second engagement element (33), and a controller. The controller includes an electronic control unit (40) configured to perform an idling mode after the clutch (CL1) is disengaged while the vehicle is traveling. The idling mode is a mode in which the rotary machine (MG2) rotates in a state where the rotation speed of the second engagement (33) element is lower than the rotation speed of the first engagement element (32).
Abstract:
The invention relates to a hybrid module for a drive train of a vehicle having an internal combustion engine and a transmission, wherein the hybrid module operates between the internal combustion engine and the transmission and has an electric drive, a clutch, and a freewheel, and wherein the clutch and the freewheel are provided parallel to each other in order to transmit torque from the internal combustion engine toward the transmission, the freewheel transmits torque coming from the internal combustion engine to the transmission and opens for torque directed in the opposite direction, and a portion of the torque produced by the internal combustion transmitted by the freewheel can be set by setting a torque that can be transmitted by the clutch so that the vehicle can be driven by the internal combustion engine or the electric drive or both at the same time.
Abstract:
A hybrid powertrain includes a hybrid electro-mechanical transmission and a power source. A planetary gear set having a first, a second, and a third member connects the power source with a first and a second motor/generator. A battery is operatively connected to the motor/generators for receiving power therefrom and delivering power thereto. An input member rotates with the first member, the first motor/generator rotates with the second member, and the second motor/generator rotates with the output member. A first torque-transmitting mechanism is engagable to connect the second motor/generator for rotation with the third member. The battery and the second motor/generator provide an electric-only operating mode to power the output member when the first torque-transmitting mechanism is not engaged; the power source, planetary gear set and first motor/generator thereby being disconnected from the output member during the electric-only operating mode to prevent parasitic drag.
Abstract:
A control system for a vehicle, the control system includes a selectable one-way clutch, a motor, and an electronic control unit. The electronic control unit is configured to (i) execute rotation control to control the motor such that negative differential rotation changes into positive differential rotation when the selectable one-way clutch is switched from a disengaged state to an engaged state while differential rotation of the selectable one-way clutch is negative and (ii) initiate engagement control by a switching mechanism such that a projecting operation of the selectable one-way clutch is completed while the differential rotation is negative.
