  • Patent number: 7487026
    Abstract: A vehicle drive force control apparatus is provided that can stabilize the output of the electric motor even if the engine rotational speed experiences an acute change. The output of an engine is delivered to the left and right front wheels through a transmission and also to an electric generator. The output voltage of the electric generator is supplied to an electric motor and the output of the electric motor drives the left and right rear wheels. The drive force control device predicts if the rotational speed of the engine will decrease or increase acutely based on the upshifting and downshifting of the transmission and adjusts the field current of the electric generator up or down before the acute change in the engine rotational speed occurs.

  • Patent number: 7192022
    Abstract: An apparatus for reversing a sheet, such as a banknote, from a front face to a rear face. In the reversing apparatus a first end of a common path communicates with an exit of a first conveyance path, a second end of common path communicates with an exit of a second conveyance path, and the first end of common path communicates with a merging path. Since the merging path is immediately after the common path, no delay is caused in the timing of feeding a banknote into the next processing step, improving reversing process performance. A first reversing roller rotates based on the on or off condition of a first electromagnetic clutch and a second reversing roller rotates based on or off condition of a second electromagnetic clutch. A banknote can be quickly and surely conveyed in the common path.

  • Patent number: 7182168
    Abstract: A vehicle driving force control apparatus is configured to provide a vehicle drive force control apparatus that can expand the operating region within which an electric motor can be driven in a stable manner. The output of an engine is delivered to the main drive wheels through a transmission and also to an electric generator. The output voltage of the electric generator is supplied to the electric motor and the output of the electric motor drives the subordinate drive wheels. When it is determined that the generator output voltage will not be sufficient to meet the requirement of the electric motor, the amount of acceleration slippage allowed at the left and front wheels is increased.

  • Patent number: 7140460
    Abstract: A driving force control apparatus is provided for a vehicle capable of preventing a shock from being generated by disengaging a clutch disposed between a subordinate drive source and subordinate drive wheels during vehicle travel. When a transition determination is made in which the clutch will be released, e.g., from a four-wheel drive state to a two-wheel drive state, a clutch release section disengage the clutch, upon the drive torque of the drive source substantially reaching a target drive torque in which a difference between an output torque of the clutch and an input torque of the clutch is smaller than a prescribed value in response to the transition determination.

  • Patent number: 7004018
    Abstract: A vehicle driving force control apparatus controls a control torque command of an electric motor based on a power supplying condition of an electric power source. The power source supplies electric power to the electric motor that drives at least one wheel of the vehicle. An electric power supplying status detecting section determines an electric power supplying capacity of the electric power source based on the power supplying condition of the power source, while an electric motor torque control section controls the control torque command of the electric motor based on the power supplying condition determined by the electric power supplying status detecting section. Preferably, an internal combustion engine that drives at least one other wheel also drives a generator that acts as the power source of the electric motor. The vehicle driving force control apparatus is especially useful in a four-wheel drive vehicle.

  • Patent number: 6969337
    Abstract: A vehicle driving force control apparatus is provided for a vehicle having an electric motor transmitting a drive torque to a first wheel, and a clutch installed between the electric motor and the first wheel. The vehicle driving force control apparatus basically comprises a clutch control section and a motor control section. The clutch control section is configured to control engagement and release of the clutch. The motor control section is configured to control a motor response characteristic by increasing the motor response characteristic of the motor from a first response characteristic to a second response characteristic when the clutch control section releases the clutch. Preferably, the vehicle driving force control apparatus is configured to cancel insufficient torque generation due to undershoot armature current when controlling armature current of an electric motor and transmitting torque to subordinate drive wheels.

  • Patent number: 6905438
    Abstract: A vehicle powertrain includes an electric motor (4) and a clutch (12) between the electric motor and a motor driven road wheel (3L, 3R). Powertrain play between the electric motor (4) and the road wheel is eliminated upon determination that powertrain play elimination (PPE) is needed for motor torque transmission to the motor driven road wheel. The PPE includes controlling engagement of the clutch and regulating the electric motor to produce a very small amount of motor torque required for PPE.

  • Publication number: 20040070139
    Abstract: Apparatus for reversing a sheet such as a banknote from a front face to a rear face, and vice versa. A reversing apparatus 1 is constructed on the basis of a path configuration wherein one end of common path S communicates with an exit of a first conveyance path 6, the other end of common path S communicates with an exit of a second conveyance path 7, and the one end of common path S communicates with a merging path 8. Since this path arrangement is provided with the merging path 8 immediately after the common path S, no delay is caused in the timing of feeding a banknote R into the next processing step. As a result, an improvement is made in reversing process performance. Furthermore, first reversing roller 21 undergoes rotation based on on/off of first electromagnetic clutch 23 and, likewise, second reversing roller 22 also undergoes rotation based on on/off of second electromagnetic clutch 27. Thus, the banknote R can be quickly and surely conveyed in the common path S.
