Disclosed is a wheeled vehicle. The wheeled vehicle includes various features for operation by a rider, such as a throttle actuation assembly and various components for operation and manipulation of the vehicle.

A control method of a hybrid vehicle includes: confirming whether or not the driving mode of the vehicle is an EV mode when a controller senses shift of the position of a shift lever from the position R to the position D or from the position D to the position R; applying reverse-directional motor torque to a motor through the controller so that a motor speed is synchronized with the speed of an engagement-side clutch, as a result of confirmation of the driving mode, if the driving mode of the vehicle is the EV mode; and executing normal driving of the vehicle by applying regular-directional motor torque to the motor through the controller after synchronization of the motor speed with the engagement-side clutch speed.

A hybrid vehicle driving device includes: a first motor generator; a second motor generator; an input shaft; an output shaft; a rotating member rotatably linked to the output shaft; a connection member to which the first motor generator is connected; a connection mechanism which connects and disconnects the connection member and the rotating member; a one-way clutch connecting the input shaft and the connection member; a synchronization control portion synchronizing the rotational speed of the first motor generator with the rotational speed of the rotating member; a first engine control portion maintaining the rotational speed of an engine; a connection portion connecting the connection member and the rotating member to each other; and a second engine control portion controlling the engine such that the rotational speed of the input shaft is synchronized with the rotational speed of the connection member.

Disclosed is a method for control of a vehicle with a drive system comprising an output shaft in a combustion engine and a planetary gear with a first and a second electrical machine connected via their rotors to the components in the planetary gear, a supply of electrical power to electrical auxiliary units and/or loads present in the vehicle is carried out, by way of the combustion engine being kept running with its output shaft connected with the second electrical machine's rotor, and the electrical auxiliary units and/or loads being supplied with electrical power via the first electrical machine and/or the second electrical machine.

An all-terrain vehicle (ATV) a frame extending along a longitudinal centerline of the ATV. Additionally, the ATV includes a plurality of ground engaging members operably coupled to the frame which includes a first ground-engaging member and a second ground-engaging member positioned on a first side of the longitudinal centerline and a third ground-ground engaging member and a fourth ground-engaging member positioned on a second side of the longitudinal centerline. The ATV further includes a straddle seat supported by the frame and configured to support an operator, an engine supported by the frame, and an engine air inlet fluidly coupled to the engine and positioned forward of the straddle seat.

In accordance with an example embodiment, a transmission may include a first mode in which a low range clutch is engaged and a first synchronizer is in a first engaged condition causing an output shaft to rotate relative to a first range shaft based upon a ratio of a first range gear to a second range gear. The transmission may include a second mode in which a high range clutch is engaged and a second synchronizer is in a first engaged condition causing the output shaft to rotate relative to a second range shaft based upon a ratio of the first range gear to the second range gear. A shift from the first mode to the second mode includes engaging the second synchronizer in the first engaged condition before disengaging the low range clutch and engaging the high range clutch.

A method for controlling an electric machine (EM) during a synchronisation procedure of a first shaft and a second shaft, whereby said first shaft is in drive connection with an output shaft of said electric machine (EM) and said first shaft and said second shaft are connectable over a synchronisation mechanism, comprising: controlling the output shaft to a speed (na) close to a target speed (nt) of said second shaft by using speed control; continuously controlling an electrical torque of said electrical machine (EM), such that an output torque (Tout) of said electric machine (EM) becomes essentially equal to zero; and controlling said synchronisation mechanism to synchronise the speed of the first shaft and the second shaft.

A power transmission apparatus for a vehicle may include a first input shaft directly connected to an engine, a second input shaft selectively receiving torque of the engine through a first clutch, a third input shaft selectively receiving the torque of the engine through a second clutch, an intermediate shaft disposed in parallel with the first, second, and third input shafts, a transfer gear fixedly disposed on the intermediate shaft, an first shifting member outputting first and second preliminarily shifted torques, an second shifting member outputting third and fourth preliminarily shifted torques, a third shifting member outputting eight forward speed stage stages and one reverse speed stage, and an auxiliary power source disposed on a supply of the torque transmitted from the first shifting member and the second shifting member to the third shifting member and supplying torque to the third shifting member.

An all-terrain vehicle (ATV) includes a plurality of ground engaging members and a frame supported above a ground surface by the plurality of ground engaging members. The frame extends along a longitudinal centerline of the ATV. The ATV further includes an operator seat supported by the frame, an engine supported by the frame, and a continuously variable transmission (CVT) supported by the frame and operably coupled to the engine. Additionally, the ATV includes a CVT cooling air inlet fluidly coupled to the CVT and positioned forward of a forward end of the operator seat, and a CVT cooling air outlet fluidly coupled to the CVT and positioned forward of the forward end of the operator seat.

A control method of a hybrid vehicle includes: confirming whether or not the driving mode of the vehicle is an EV mode when a controller senses shift of the position of a shift lever from the position R to the position D or from the position D to the position R; applying reverse-directional motor torque to a motor through the controller so that a motor speed is synchronized with the speed of an engagement-side clutch, as a result of confirmation of the driving mode, if the driving mode of the vehicle is the EV mode; and executing normal driving of the vehicle by applying regular-directional motor torque to the motor through the controller after synchronization of the motor speed with the engagement-side clutch speed.
