A control unit is provided for an automatic transmission of a vehicle. The vehicle has a gear selection operating element which allows a user of the vehicle to set different gear stages of the transmission by actuating the gear selection operating element, and the vehicle has at least one setting operating element which allows the user to change the value of a parameter of a function of the vehicle by actuating the setting operating element when the function of the vehicle is activated. The control unit is designed to detect an actuation of the gear selection operating element for a period of time which is equal to or longer than a minimum duration and to determine that the function of the vehicle is deactivated. In response thereto, the control unit is additionally designed to allow a manual change of the transmission gear by actuating the at least one setting operating element.

A shifter abnormality diagnosis device for a shifter used in an automatic transmission having a manual mode, the shifter including a first switch for outputting a signal corresponding to the position of a select lever and a second switch for outputting a signal corresponding to the position of the select lever if the select lever is located in at least one of an upshift range or a downshift range, wherein the abnormality diagnosis device is configured to perform an abnormality diagnosis of the second switch on the basis of an output signal of the second switch and prohibit the abnormality diagnosis of the second switch if it is determined that the select lever is not located in any one of forward ranges including the upshift range and the downshift range on the basis of an output signal of the first switch.

A shifter simulator system comprising a frame with a gear stick hinge, a gear stick that is hingedly connected to the frame via the gear stick hinge, and a moveable frame part configured for moving relative to the frame and provided with a first contact surface and a second contact surface. The shifter simulator system also includes a magnetic contact and a tilting element configured for tilting around a tilting axis via a tilting connection in response to a movement of the gear stick and providing a first lever, and wherein the tilting element is provided with a first contact element and a second contact element configured for engaging the respective first and second contact surfaces of the moveable frame part providing a second lever, and by moving the moveable frame part defining a shifter movement with the magnetic contact. The first and/or second levers are adjustable.

A gearbox system for a vehicle includes an automated manual gearbox; a gearbox control device which controls the gearbox; a monostable toggle switch which is movable by a user in two deflection directions to select a plurality of driving ranges of the gearbox control device, and a visual device which displays graphically a gearshift diagram with driving ranges selectable by the monostable toggle switch. The gearbox control device has a further driving range which cannot be selected by the monostable toggle switch but can be exited by moving the monostable toggle switch. The visual device has at least one display to display a symbol indicating at least one deflection direction by which the further driving range can be exited. The gearbox control device may control the at least one display such that the symbol is only displayed when the further driving range is selected.

There is provided a shift device for a straddle-type vehicle that is configured to cause a transmission device to perform a shift change in accordance with rotation of a shift shaft. The shift device includes: a shift lever provided with an operation portion that is configured to receive a shift operation; a shift sensor provided on the shift shaft so as to be integrally rotatable with the shift shaft; and a shift rod that couples the shift lever and the shift sensor. The shift sensor is configured to detect the shift operation on the shift lever in accordance with a movement of the shift rod. The operation portion and the shift sensor are positioned at the same side in a manner of sandwiching the shift rod.

The present invention relates to an improved go-kart vehicle that has shifter functionality using a dash-mounted shifter control. The go-kart is configured as a rear-wheel drive go-kart for adults, and features a front mounted engine covered by a hood, headlights for illumination, front steering wheel mounted brakes for controlling front wheels, an emergency brake handle for use during drifting and sliding, a dash mounted up-shifter/down-shifter and a removable roll cage. A seat is disposed for a driver to sit with lumbar supports to keep the driver centered. A chain drives a sprocket of a rear axle, and the engine drives the rear axle for driving the go-kart in a smooth manner. The shifter control is used for providing an increased amount of power to the vehicle to generate speed.

A control unit is provided for an automatic transmission of a vehicle. The vehicle has a gear selection operating element which allows a user of the vehicle to set different gear stages of the transmission by actuating the gear selection operating element, and the vehicle has at least one setting operating element which allows the user to change the value of a parameter of a function of the vehicle by actuating the setting operating element when the function of the vehicle is activated. The control unit is designed to detect an actuation of the gear selection operating element for a period of time which is equal to or longer than a minimum duration and to determine that the function of the vehicle is deactivated. In response thereto, the control unit is additionally designed to allow a manual change of the transmission gear by actuating the at least one setting operating element.

A continuously variable transmission has a variator (4) structured to be able to continuously vary a transmission ratio and a control unit (100). The control unit (100) continuously varies a transmission ratio of the variator (4) in a continuously variable shift mode. In a manual mode in which a manual mode switch (36c) is ON, the transmission ratio is maintained. When a shift switch (36a, 36b) is operated by a driver during the manual mode, the control unit (100) performs shift of the variator (4) so as to change an input rotation speed of the variator (4) by a predetermined rotation speed (ΔN1) regardless of a vehicle speed.

A gear shift operation device for a vehicle to which a multiple-stage automatic transmission is mounted, is provided. By a control lever being manually operated in a range switchable mode, a range position is switched at least between a D-range where automatic transmission is performed and an R-range, and by the control lever being manually operated in a manual transmission mode, a gear change is performed. An operation reaction force when the control lever is manually operated is set larger when the gear change is performed in the manual transmission mode than when the range position is switched in the range switchable mode.
