Abstract: In exemplary implementations, a bicycle has “power pedaling”, in which a rider's pedaling efforts are augmented by an electric motor. The rider can control the motor simply by pedaling. It is desirable that the motor torque not exceed the rider torque; otherwise the motor overpowers the rider. A radial flexure is part of the drivetrain that transmits torque from the rider to the back wheel. One part of the flexure is connected to the back wheel casing; another part of the flexure is connected to the freewheel. If motor velocity exceeds rider velocity, this causes the flexure to elastically deform. Two sensors measure the deformation, which is equal to the difference between the angular displacements of the casing and freewheel, respectively. A PD controller seeks to make this difference equal to zero, by controlling voltage levels in the motor (and thus controlling the torque contributed by the motor).

Abstract: A control device for a vehicular drive system is disclosed as including reverse drive for suppression means operative to preclude output member, such as an output shaft and drive wheels, of an automatic transmission portion from inputting a reverse drive force to a differential portion. This prevents a power transmitting member from rotating in a direction opposite to a rotational direction of the same with a running position being set. This suppresses a first electric-motor rotation speed, determined with an engine rotation speed and a power transmitting member rotation speed based on the relationship on mutually relative rotation speeds in the differential portion, from increasing to a high level. This results in improved durability of a first electric-motor.

Abstract: A control device for hybrid vehicle drive apparatus has a differential mechanism operative to perform a differential action and an electric motor. The control device prevents a second electric motor from reaching a high-speed rotation with a likelihood of degradation occurring in durability of the second electric motor when a “D” position is switched into an “N” position during a running of a vehicle. When a shift lever (49) is shifted into the “N” position during the vehicle running to interrupt a power transmitting path of an automatic shifting portion (20), a differential action of a power distributing mechanism (16) is limited. A limited differential action suppresses increases in rotation speeds of rotary members such as a clutch or a brake of the automatic shifting portion (20), a second electric motor (M2) and a differential-portion planetary gear (P0) or the like. Thus, degradation in durability of such rotary members due to high-speed rotations thereof can be minimized.

Abstract: When a torque control value (TR) is larger than a threshold value and vehicular speed (SV) is lower than a threshold value an upper temperature limit setting unit sets the upper temperature limit of a motor generator at an upper temperature limit (TS2) higher than a normally set upper temperature limit (TS1). A torque limitation control controls limiting a torque of the motor generator, as based on a motor temperature (T) and the upper temperature limit set by the upper temperature limit setting unit.

The electric motor is used for pre-lubricating and warming the transmission such that, with the vehicle clutch disengaged, the lubricant pump of the transmission is driven by the electric motor so bearings are supplied with lubricant before the engine is started, and the heat, produced by splashing the lubricant, additionally warms the transmission.

Abstract: An apparatus and method are provided to execute synchronous shifting in a powertrain system having multiple torque-generative devices each operable to independently supply motive torque to the transmission device. The exemplary transmission device comprises a two-mode, compound-split, hybrid electro-mechanical transmission. Operation includes operating in an initial fixed gear ratio, operating the transmission in a mode operation, and, operating the transmission in a final fixed gear ratio. The control system reduces reactive torque of a clutch activating the initial gear, and deactivates the first torque-transfer device when the reactive torque is less than a predetermined value. It determines that speed of an input shaft to the transmission is substantially synchronized with a rotational speed of the second torque-transfer device, and actuates the second torque-transfer device.

Abstract: In response to the driver's brake OFF operation after a gearshift operation of a gearshift lever to a parking position, a motor MG2 is controlled to sequentially output a torque in a backward direction of a vehicle and a torque in a forward direction of the vehicle. Gears are accordingly engaged in a parking lock mechanism during rotation of a parking gear by an angle corresponding to half a tooth in the backward direction of the vehicle or during subsequent rotation of the parking gear by an angle corresponding to one tooth in the forward direction of the vehicle. This arrangement effectively ensures gear engagement in the parking lock mechanism, while desirably reducing a moving distance from a vehicle stop position before gear engagement in the parking lock mechanism.
