  • Publication number: 20170087995
    Abstract: A vehicle includes an electric motor and a clutch disposed on a drive shaft. The electric motor is disposed on one side from a middle of the vehicle in the vehicle width direction, while the clutch and a sprocket are disposed on a second side from the middle of the vehicle in the vehicle width direction. The clutch is connected to a clutch lever so that the state of engagement of the clutch is changed in response to an operation of the clutch lever. It is thus possible to increase the degree of freedom in torque transmission control by a driver, to increase an output torque of the electric motor, and to reduce the size of the clutch.

  • Patent number: 9586582
    Abstract: In a driving support system, a target speed profile computing unit determines a target speed on the basis of a safe-condition confirmation end point that is set to a predetermined position in a travel direction of a host vehicle. The safe-condition confirmation end point is a point at which the host vehicle passes through a section following the safe-condition confirmation end point in advance of a moving object that appears from blind areas. In this way, by determining the target speed based on the safe-condition confirmation end point, the drive support control unit is able to support driving in consideration of driving action at the time when the driver actually causes the host vehicle to pass through near the blind areas. Thus, it is possible to appropriately support driving along a feeling of the driver such that inconvenience and a feeling of strangeness are reduced.
