Abstract:
1. A power transmitting apparatus for a vehicle, which has a driving-power source for generating a driving power for the vehicle, comprising; a planetary gear device having a first rotating member, a second rotating member and a third rotating member, the first rotating member being operatively connected to an energy accumulating device via an input shaft, the second rotating member being connected to a driving wheel of the vehicle via a driving shaft to which the driving-power source is operatively connected, the third rotating member being connected to a torque adjusting device; wherein the torque adjusting device generates a braking torque for applying the braking torque to the third rotating member, wherein the first rotating member, the second rotating member and the third rotating member are rotatably coupled to one another so that a rotational force is operatively transmitted to the energy accumulating device via the planetary gear device; a block-off device provided between the first rotating member and the input shaft for blocking off a power transmission from the input shaft to the first rotating member; and a control unit configured to control an operation of the power transmitting apparatus, wherein the control unit carries out a regeneration control when there is no demand for generating the driving power at the driving-power source, so that a kinetic energy of the vehicle is transmitted to the energy accumulating device via the planetary gear device and the input shaft and the kinetic energy is accumulated in the energy accumulating device, and wherein the control unit further carries out a speed-difference adjusting control when the regeneration control is not carried out, so that the braking torque to be generated at the torque adjusting device is adjusted so that a difference between a rotational speed of the first rotating member and the input shaft is reduced.
