A drive assistance device (24) for a saddle type vehicle (1) includes a ride sensor (37) configured to detect a ride attitude of a rider, a vehicle body behavior generating part (25) configured to generate a behavior on a vehicle body by a prescribed output, and a controller (27) configured to control driving of the vehicle body behavior generating part (25), and wherein, when the vehicle body behavior generating part (25) is actuated regardless of the operation of the rider, the controller (27) firstly controls the vehicle body behavior generating part (25) such that a low output that is lower than a predetermined original target output is generated as a predictive action, and sets an output value after that according to a change of detection information of the ride sensor (37) generated by the low output.

An apparatus for providing a secondary power source for an electric vehicle, the apparatus attachable to the electric vehicle and having at least one secondary electrical power storage unit for storing electrical energy for delivery to the electric vehicle as required to replace the primary power source, a power connection assembly to connect the at least one secondary power source to the electric vehicle and a control system to control supply to the electric vehicle.

An electric motorcycle includes a housing for housing an electric motor and/or a transmission. The housing is positioned at the center of the electric motorcycle in a front view. An internal cooling device and/or an electronic component and two cooling elements extend outward from opposite sides of the housing. Exterior cooling ribs are arranged on the cooling elements. The cooling ribs extend in the longitudinal direction of the electric motorcycle, such that the cooling elements and the cooling ribs are directly in contact with the air surrounding the electric motorcycle. The cooling device and/or the electronic component is, at least in portions, housed in and thermally connected to at least one of the cooling elements.

A mounting structure for a fuel shutoff valve unit (U) includes a valve device (50) which is provided in a fuel tank (31) of a saddle type vehicle (1) and in which a breather passage (Y) which discharges volatile fuel to the outside is formed and a valve (51) which prevents leakage of liquid fuel is provided, wherein, in the saddle type vehicle including a filler tube (F) which is provided inside the fuel tank (31) and supplies fuel supplied from the outside to the inside of the fuel tank (31), a support member (B) which is provided on an outer peripheral surface of the filler tube (F) and supports the fuel shutoff valve unit (U) inside the fuel tank (31) is provided.

A clutch pedal for an electrically operated clutch system simulates the pedal forces of a hydraulically actuated clutch. An operating element is pivotably supported on a mounting so as to move along an operating path between a non-operating position and an operating position. A restoring spring applies a force towards the non-operating position. At least one friction element rubs against a curved friction surface when the operating element is pivoting along the operating path. The friction element is spring-loaded against the friction surface. During operation between the operating position and the non-operating position, the friction element moves over a cam lobe of the friction surface. The friction element is elastically movable radially in relation to the curved friction surface.

Provided is a vehicle speed-change system including the following: a transmission; a transmission case that retains the transmission; a shift mechanism that performs a speed-change operation of the transmission; and a shift actuator that operates the shift mechanism. The shift actuator includes the following: a motor; a transmission mechanism that transmits rotation of the motor; and an actuator output shaft that outputs motive power transmitted by the transmission mechanism. The shift actuator is fixed to a side surface of the transmission case, and is arranged such that at least a portion of the motor overlaps the shift mechanism in a side surface view of the vehicle.

A hybrid drive system for electric vehicle is disclosed. The system includes a rear wheel. The system also includes a first motor mechanically coupled to the rear wheel and an internal combustion engine. The first motor is configured to drive power for the electrical vehicle to reach a fraction of a predetermined threshold value of rotations per minute (RPM). The system also includes a second motor mechanically coupled to the internal combustion engine via the chain drive transmission unit with a one way bearing. The second motor is configured to receive an activation signal to power the internal combustion engine to transfer the power driven to the rear wheel via the continuously variable transmission unit upon attaining the fraction of the predetermined threshold value of rotations per minute (RPM) by the first motor.

A hybrid vehicle includes: an oil passage including a common oil passage through which lubricating oil discharged from an oil pump flows, an engine lubricating oil passage extending from the common oil passage toward an engine internal space, and a transmission lubricating oil passage extending from the common oil passage toward a transmission internal space; and a variable throttle valve that can change a flow rate in the transmission lubricating oil passage. The variable throttle valve increases an opening degree of the variable throttle valve in a mode transition in which a first traveling mode in which the hybrid vehicle travels by driving power of an engine transitions to a second traveling mode in which the hybrid vehicle stops the engine and travels by the driving power of the electric motor.
