A continuously variable transmission (CVT) is provided for use on a recreational or utility vehicle. The CVT is electronically controlled by at least one control unit of the vehicle. The CVT includes a primary clutch having a first sheave and a second sheave moveable relative to the first sheave. An actuator controls movement of the second sheave.

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 control device for a vehicle having: an engine; a variator arranged downstream of the engine in a power transmission path connecting the engine and drive wheels; a mechanical oil pump that is driven by the engine and supplies hydraulic pressure to the variator; and an electric oil pump that supplies hydraulic pressure to the variator, wherein the control device for the vehicle has a controller that executes a low standby control which downshifts the variator by moving a belt of the variator in a radial direction during stopping of the vehicle. The controller limits an output of the engine and increases an amount of oil discharged by the electric oil pump when executing the low standby control.

A control device for a vehicle having: an engine; and a variator arranged downstream of the engine in a power transmission path connecting the engine and drive wheels, wherein the control device for the vehicle has a controller that executes a low standby control which downshifts the variator by moving a belt of the variator in a vertical direction (radial direction) during stopping of the vehicle. After starting the low standby control, the controller releases an output limit of the engine based on an actual secondary pressure of the variator.

A method of controlling an engine and a transmission of a hybrid vehicle includes steps of: determining whether the vehicle starts, determining an engine RPM and a gear stage of a transmission if the vehicle has started, determining whether the engine RPM has reached an engine speed control point, determining an engine target RPM and an engine target RPM slope of the vehicle when it is determined that the engine RPM has reached the engine speed control point, controlling the engine RPM of the vehicle to follow the engine target RPM and the engine target RPM slope, determining whether the engine RPM has slipped compared to the target engine RPM, and performing PID control to follow the engine target RPM if the engine RPM slips compared to the engine target RPM.

A compression-based speed limiting for a driveline including a transmission is described herein. The driveline controller detects over speeding and controls the ratio of the transmission to therefore increase compression of the prime mover and therefore limit speed.

A control device for an automatic transmission in a vehicle with a constant speed travel mode includes: a determination section that determines whether the vehicle is traveling on a slope road; a slope adaptation control section that implements a first transmission shift control if not traveling on a slope road and, if traveling on a slope road, implements a second transmission shift control for selecting a transmission shift position of a lower speed than case of not traveling on a slope road; a delaying section that, upon switching from the second transmission shift control to the first transmission shift control, implements an upshift delay control for performing upshift one by one at a predetermined time interval; and a setting section that, in case of traveling at the constant speed travel mode, sets the time interval shorter in comparison with case of traveling not at the constant speed travel mode.
