A straddled vehicle including a radiator, a radiator fan disposed behind the radiator and configured to generate air passing through the radiator and flowing rearward, a fan cover disposed behind the radiator fan and including a lateral blowing port configured to blow out sidewards the air flowing rearward from the radiator, a side cover covering the radiator laterally and having an opening formed therein, an inner panel disposed between the side cover and the radiator, to thereby define an accommodation space between the inner panel and the side cover, and an electrical component disposed in the accommodation space. The inner panel includes a slope that is located rearward of the radiator, slants with respect to aright-and-left direction of the straddled vehicle, is configured to lead the air blown out from the lateral blowing port to the opening in the side cover, and divides the accommodation space.

The present invention obtains a controller and a control method capable of improving safety of adaptive cruise operation in a motorcycle.

In the controller for operation of the motorcycle, to which a surrounding environment detector is mounted, an adaptive cruise operation performing section controls deceleration to be generated by the motorcycle in adaptive cruise operation to be equal to or lower than an upper limit value or to be lower than the upper limit value, determines a collision possibility of the motorcycle on the basis of the upper limit value during the adaptive cruise operation, and performs warning operation that acts on a tactile organ of a rider of the motorcycle when determining that the collision possibility is high.

A quickshifter-equipped vehicle control unit includes an engine speed calculator configured to calculate an engine speed and a shift controller configured to operate in a quick shift mode and in a normal shift mode. The quick shift mode is a mode in which upon detection of the shift operation, the shift controller adjusts an output of an engine while keeping a main clutch in an engaged state, and the normal shift mode is a mode in which upon detection of the shift operation, the shift controller controls a clutch actuator to bring the main clutch into a disengaged state. The shift controller selects the quick shift mode when the engine speed is higher than a predetermined rotational speed threshold, and selects the normal shift mode when the engine speed is lower than the rotational speed threshold.

The present invention provides a control system and a control method capable of appropriately supporting driving of a motorcycle by a rider. The control system includes a tracking target vehicle identifying unit that identifies a tracking target vehicle of adaptive cruise operation, a vehicle position information acquiring unit that acquires information on the relative position of the tracking target vehicle with respect to the motorcycle during traveling, a control amount setting unit that sets a control amount in the adaptive cruise operation, and an execution unit that causes the motorcycle to execute the adaptive cruise operation, and further includes a lane position information acquiring unit that acquires information on the relative position of a lane boundary with respect to the motorcycle during traveling, in which the tracking target vehicle identifying unit identifies the tracking target vehicle, based on the position information acquired by the lane position information acquiring unit.

A vehicle includes at least one of an electric vent valve configured to open and close an outside-air-introduction passage of a canister or an electric suction pump configured. to suck gas in a gas passage through which the gas flows. The canister and at least one of the vent valve or the suction pump are disposed such that at least one of a virtual-left-right-center plane that includes a center in a left-right direction and is perpendicular to the left-right direction, a virtual-front-rear-center plane that includes a center in a front-rear direction and is perpendicular to the front-rear direction, or a virtual-up-down-center plane that includes a center in an up-down direction and is perpendicular to the up-down direction is located between a gravity center of the canister and at least one of a gravity center of the vent valve or a gravity center of the suction pump.

A transmission includes a shift drum, an angular sensor, and a control unit. The control unit has reference values of the output values at a first rotation angle and a second rotation angle of the shift drum. The control unit is configured to obtain the output values at the first rotation angle and the second rotation angle as a first output value and a second output value, respectively. The control unit is configured to correct the output value output between the first rotation angle and the second rotation angle based on a difference between the first output value and the reference value at the first rotation angle and a difference between the second output value and the reference value at the second rotation angle.

The present invention obtains an assistance system capable of assisting with function setting of a straddle-type vehicle by a rider, a portable wireless terminal used for such an assistance system, a control method for such an assistance system, a control method for such a portable wireless terminal, and a program run on such a portable wireless terminal.

In an assistance system (1), an acquisition section (51) of a portable wireless terminal (50) wirelessly acquires information on the function setting operated on an input device (11) of a straddle-type vehicle (10), and an input section (52) of the portable wireless terminal (50) provides a guidance corresponding to the information on the function setting operated on the input device (11) of the straddle-type vehicle (10) when accepting the operation of the function setting by the rider.

A system and method for operating the same includes a drive sprocket assembly, a clutch lever, a user interface generating a reverse signal at a user interface, a wheel speed sensor generating a wheel speed signal, a transmission position sensor generating a transmission position signal and a vehicle control module receiving the reverse signal, the wheel speed signal and the transmission position signal. The vehicle control module engages a reverse gear at a drive sprocket in response to the reverse signal, the wheel speed and transmission gear position and controls the drive sprocket assembly in response to the clutch lever.

A fluid vent valve (1) for a fuel tank, comprising: a valve body (10) having an inlet opening connected or connectable to a tank, an outlet opening and a main chamber (13) interposed between said inlet opening and said outlet opening (12); a piston (20) inserted or insertable in the main chamber (13) and movable therein so as to define a closed configuration and an open configuration; a pendulum (30) hinged to the valve body (10) and coupled to the piston (20) so as to promote a movement of the piston (20) between the two configurations; a flow reducer (40) operatively interposed between the outlet opening (12) and the piston (20).

A wheel (1) includes a rim (2) and a wheel center (3) made from a fiber reinforced composite material. The wheel center (3) includes a tubular middle section (6) having a center opening (7) extending in the direction of a wheel axis (19) and having a first and a second end (8, 9). A hub (5) includes a first flange ring (10) and a second flange ring (11). At least one of the flange rings (10, 11) and the tubular middle section (6) are interconnected to each other by a form fit interconnection (12, 13).
