A hydrostatic transmission pedal stroke limiter includes a stop connected through a linkage to a range shift lever for limiting the travel of the hydrostatic transmission actuator arm when the range shift lever is in the low gear range, and reducing sound significantly when operating in the low gear range.

A controller is configured to output a control command for controlling at least one driveline component according to a control map. The control map may define a dependence of the control command on at least one of: a control position of an input device, and at least one first condition of the driveline. The controller may also be configured to receive at least one input signal, the input signal may have a plurality of signal values recorded at different times. The signal values of the at least one input signal are indicative of at least one of: the control position of the input device, the at least one first condition of the driveline, and at least one second condition of the driveline. The controller may also be configured to derive a feature from the plurality of signal values and adapt the control map based on the derived feature.

A work vehicle includes an engine, a hydrostatic transmission, a work implement pump driven by the engine, a work implement driven by hydraulic fluid discharged from the work implement pump, an accelerator, a first sensor configured to output a signal indicative of an operation amount of the accelerator, a work implement operating member, a second sensor configured to output a signal indicative of an operation amount of the work implement operating member, and a controller. The controller is configured to receive signals from the first sensor and the second sensor, determine a target input horsepower input to the hydrostatic transmission from the operation amount of the accelerator, and determine a target rotational speed of the engine from the target input horsepower and the operation amount of the work implement operating member.

A vehicle control device including: a road gradient acquisition unit configured to acquire a road gradient of a road on which a vehicle is currently traveling; a travel section determination unit configured to determine a forward travel section that is a travel section having a different road gradient from a current travel section in which the vehicle is currently traveling and that is ahead in a travel direction of the vehicle; and a horsepower limitation unit configured to limit an output horsepower of an engine based on a travel resistance of the vehicle, in which the horsepower limitation unit is configured to release the output horsepower limitation of the engine in a case where the travel resistance in the forward travel section is greater than the travel resistance of the vehicle in the current travel section.

In this vehicle control device (10), which controls operation of a vehicle provided with a transmission including a direct gear and an overdrive gear, which is a gear with a lower gear ratio than that of the direct gear, a travel segment determination unit (15) determines a next travel segment which, forward in the travel direction of the vehicle, has a road slope different from that of the current travel segment where the vehicle is currently traveling. A next gear stage selection unit (16) determines a next gear stage, which will be the gear stage of a transmission in the next travel segment, on the basis of the speed of the vehicle, an equal fuel consumption map of the engine of the vehicle, and the travel resistance of the vehicle in the next travel segment estimated on the basis of the road slope in the next travel segment. The next gear stage selection unit (16) selects the next gear stage referring to different equal fuel consumption maps depending on whether the gear stage of the transmission is the direct gear or whether the gear stage of the transmission is a normal gear.

Methods and systems for a hydromechanical transmission. In one example, a vehicle system includes a hydromechanical transmission with a power-take off (PTO) that is designed to rotationally couple to an implement. The vehicle system further includes an engine coupled to the hydromechanical transmission and a power-management control unit configured to, during a drive or coast condition, cause the power-management control unit to: determine a net available power for the hydromechanical transmission and manage a power flow between the hydromechanical transmission, a drive axle, and the implement based on the net available power.
