A system includes a driveline, a user interface, and a control system. The driveline includes an engine, a transmission, and a clutch positioned to selectively couple the engine to the transmission. The user interface is configured to facilitate operator shifting of the transmission. The control system is configured to perform a transmission auto-shift procedure where the control system monitors engine speed of the engine for a period of time following completion of a downshift event with the transmission from a first, higher gear to a second, lower gear, compares the engine speed to at least one speed threshold, and automatically upshifts the transmission from the second, lower gear back to the first, higher gear (i) following expiration of the period of time and/or (ii) in response to the engine speed exceeding the at least one speed threshold during the period of time.

Desired is a control device for a vehicle drive apparatus capable of determining an engagement failure in an engagement device when shifting a transmission device to a neutral state and making the rotational speed of a driving force source reduced. In order to shift a transmission device from a state in which an object shift speed is established and the vehicle is traveling to a neutral state in which no shift speed is established in the transmission device (#02), when an object engagement device is disengaged while maintaining engagement of a non-object engagement device and the rotational speed of a driving force source (#04, #06) is made to be reduced, an engagement failure in the object engagement device (#02, #07) is determined based on a change in the rotational speed of an input member.

A transmission system avoids activation of a sailing functionality in a vehicle. The transmission system is configured for automatic gear-shifting in an automatic mode and manual gear-shifting by a user in a manual mode. The transmission system includes a user input device configured for manually changing the operational mode between the automatic and manual modes. The transmission system includes a transmission control unit for determining a recommended gear in the automatic and manual modes. In the manual mode, an operating gear of the transmission system is detected by the transmission control unit. A change of the operational mode from manual to automatic by means of the user input device is detected, and if the detected operating gear in the manual mode when changing to automatic mode is lower than the recommended gear, the sailing functionality in the automatic mode is deactivated.

A field management machine includes a rack, a driver, a transmission, traveling wheels, a cutter, and a gear shift lever. A first shift fork controls gear shift of the cutter. A second shift fork controls gear shift of the traveling wheels. The gear shift lever includes a traveling gear shift lever and a cutter gear shift lever. The cutter gear shift lever is connected to the first shift fork. The traveling gear shift lever is connected to the second shift fork. The field management machine includes a trigger rod between the cutter gear shift lever and the traveling gear shift lever. The trigger rod is connected to the cutter gear shift lever or the traveling gear shift lever. The traveling gear shift lever pushes the trigger rod when the traveling gear shift lever is switched to a reverse gear to shift the cutter gear shift to a neutral gear.

A method of controlling gear selection in a vehicle transmission comprises detecting a change in a direction control signal (DCS) from a neutral signal state. If the current TOS is less than or equal to a predetermined neutral shift threshold TOS, the transmission selects one of a plurality of first direction gears if the DCS was changed to a first direction signal state or one of a plurality of second direction gears if the DCS was changed to a second direction signal state. If the current TOS is greater than the predetermined neutral shift threshold TOS, the transmission selects one of the plurality of first direction gears if a machine motion direction parameter indicates that the vehicle is moving in the first direction or one of the plurality of second direction gears if the machine motion direction parameter indicates that the vehicle is moving in the second direction.

A vehicle control system is provided. The vehicle control system includes a shift-by-wire device for shifting a shift gear of a speed variator mounted in a vehicle according to a requirement of an electrical signal; a vehicle speed detecting member for detecting a vehicle speed of the vehicle; a seat belt detecting member for detecting whether a seat belt provided in the vehicle is fastened or taken off; a door open/close member for detecting whether a door provided in the vehicle is opened or closed; a presence detecting member for detecting a presence state of a passenger in the vehicle; and an automatic parking control device for controlling the shift-by-wire device to shift the shift gear to a park gear when output results of one of the door open/close member and the presence detecting member, the vehicle speed detecting member, and the seat belt detecting member satisfy predetermined conditions.

A vehicle includes an engine, a torque converter, a transmission, and a control device. The torque converter is coupled to the engine. The transmission is coupled to the torque converter. The control device is configured to control operation of the transmission. The control device includes a controller configured to perform shift hold control to prevent upshift of the transmission based on a lateral acceleration value of the vehicle.
