  • Patent number: 9346453
    Abstract: A compact transmission device that alleviates shift shock and avoids engine stall at the time of deceleration. A discharge resistance changing unit changes discharge resistance of a clutch oil pressure on a side where a clutch is disconnected due to swapping of clutches in two stages. During a shift period where the clutch on a connection side is changed over from a disconnection state to a connection state, an invalid filling zone where a friction force is not generated on a clutch plate is provided. A control unit controls the discharge resistance changing unit at a time of the shift change such that the clutch on a disconnection side is brought into a state where a friction force is not generated after finishing a half clutch zone when the clutch on a connection side is in a half clutch zone after the invalid filling zone is finished.

  • Patent number: 9346456
    Abstract: A transmission control system can include a main transmission. The transmission control system can also include a sub transmission that has two forward transmission gears mechanically shiftable in response to a shift operation. The transmission control system can further include a controller that shifts the transmission gears of the main transmission by activating a shift control motor, and control the clutches configured to enable and disable transmission of a rotational driving force of an engine. When one forward transmission gear of the sub transmission is shifted to the other forward transmission gear in response to the shift operation, the controller can relax engagement of the clutch if an engine speed exceeds a clutch release speed.

  • Publication number: 20160073083
    Abstract: An image encoding method for an encoding system includes receiving a first image captured by a main camera and a second image captured by a sub camera provided in the same plane; comparing pixel values of pixels at first coordinates of each of the first and second images to obtain a first difference value; determining the first coordinates are in surface or back region in case of the first difference value is not more than or more than a first threshold value; pixel-shifting the second image by a first shift amount; and comparing the pixel value at the first coordinates of the first image with that of the second image after the pixel shift to obtain a second difference value, determining whether the first coordinates are in the surface or back region based on the second difference value, and recording into a second frame different from the first frame.

  • Publication number: 20160053833
    Abstract: To allow a rider to sense torque in a low-speed traveling mode, a control device has a forward-and-reverse clutch oil pressure controller. In a low-speed traveling mode, the forward-and-reverse clutch oil pressure controller performs hunting control on driving torque, which is transmitted to a rear wheel from a crankshaft of an engine through a clutch device, a transmission, and a drive shaft, if vehicle speed stays within a second vehicle speed range for a predetermined time.

  • Publication number: 20160039421
    Abstract: A braking force control apparatus in a motorcycle, includes a controller which controls a transmission to reduces driving force of an engine by a predetermined speed reduction ratio and transmits the driving force to a drive wheel of a vehicle, a clutch between the engine and the transmission, and brake devices which generate braking force on the wheels. The vehicle is switchable between a normal and a slow speed driving modes. In the slow speed mode the controller detects an inclination pitching angle ?, and causes the brake devices to generate braking force on at least one of the drive wheels when ??a predetermined value, then starts switching the clutch to a connected state when a driving operation is input, and gradually releases the braking force once driving force starts to be transmitted to the drive wheel.

  • Publication number: 20160039423
    Abstract: A braking force control apparatus for a saddle ride vehicle includes a transmission controller which reduces driving force of an engine by a predetermined speed reduction ratio and transmits the driving force to a drive wheel, a clutch device which connects—disconnects the driving force between the engine and the transmission, a brake device which generates braking force on the drive wheel, and a sensor which detects a state of the transmission. The transmission switches between a neutral state and an in-gear state, and when the sensor detects that the transmission is switching from the neutral state to the in-gear state, the controller causes the brake device to generate braking force on the drive wheel, and then releases the braking force upon completion of the switching to the in-gear state.
