  • Patent number: 8170792
    Abstract: A vehicle control device which can at least provide compatibility between a high grip performance and fuel efficiency or compatibility between quietness and fuel efficiency is provided. When a camber angle of a wheel 2 is adjusted to a negative camber, ground contact in a first tread 21 is increased and ground contact in a second tread 22 is decreased. Accordingly, the high grip performance or the quietness is provided. On the other hand, when the camber angle of the wheel 2 is adjusted to a positive camber, the ground contact in the first tread 21 is decreased and the ground contact in the second tread 22 is increased. Accordingly, a rolling resistance becomes low, and fuel saving is achieved. In this manner, by adjusting the camber angle of the wheel 2, the compatibility can be provided between conflicting performances of the high grip performance or the quietness and the fuel saving.

  • Patent number: 8014919
    Abstract: A vehicle control device and a vehicle are provided with compatibility between high grip performance and fuel efficiency. When a camber angle of a wheel is adjusted as a negative camber, the ground contact pressure on a first tread is increased and the ground contact pressure on a second tread is decreased, thus providing the high grip performance. On the other hand, when the camber angle of the wheel is adjusted as a positive camber, the ground contact pressure on the first tread is decreased and the ground contact pressure on the second tread is increased, thereby reducing rolling resistance and achieving fuel saving. By adjusting the camber angle of the wheel, compatibility can be provided between high grip performance and fuel saving which otherwise conflict with each other.

  • Patent number: 7246672
    Abstract: A hybrid-vehicle power train connected to an engine comprises a motor, a CVT unit, a planetary gear unit having at least two input elements, namely, first and second input elements and an output element, a first clutch for engaging/disengaging the first input element with/from a final shaft of the power train, and a second clutch for engaging/disengaging the output element with/from the final shaft of the power train. An input shaft of the CVT unit is connected to the engine and is drivingly connected to the second input element. An output shaft of the CVT unit is connected to the first input element. The motor is connected to the output shaft of the CVT unit. According this configuration, motor torque is amplified and transmitted to the final shaft when the first clutch is engaged, while motor torque is transmit directly to the final shaft when the second clutch is engaged.

  • Patent number: 6278928
    Abstract: A vehicle control device controls an automatic transmission by utilizing road information stored in a navigation system unit. In response to the road information stored in a data memory, the upper-limit of a shiftable transmission speed range is determined, thereby allowing shift-change only within the restricted transmission range. The actual down-shift is carried out after confirming a decelerating operation by the driver, such as release of the accelerator pedal, thereby providing favorable transmission control in conformity with the driver's intention.

  • Patent number: 6085137
    Abstract: There is disclosed a vehicle control system that controls an automatic transmission by utilizing road information stored in a navigation system unit. In response to the road information stored in a data memory, the upper-limit of a shiftable gear ratio range is determined, thereby allowing change of the gear ratio only within the restricted range. The actual downshift is carried out in response to initiation of a decelerating operation by the driver, such as release of the accelerator pedal, which prevents unnecessary upshift and provides favorable transmission control in conformity with the driver's intention.
