In a work vehicle according to the present invention, a control device calculates, for each of a plurality of speed-changing stages in a PTO transmission, an expected maximum rotational speed of PTO rotary power that is output from the PTO shaft when an engine rotational speed changing operation member is operated to a maximum extent, and shows, in a listed manner, the calculated results in a liquid crystal display part of a display device. The present invention can inform an operator of the maximum rotational speed of PTO rotary power that is output from the PTO shaft for each speed-changing stage in the PTO transmission without performing a speed changing operation on the PTO transmission.

Aspects of the present invention relate to a vehicle control system (1) for controlling a vehicle transfer case (3). The transfer case (3) is operable in a high range and a low range. The vehicle control system (1) is configured to determine an operating range for the transfer case (3) based on a selected vehicle operating mode. A range change signal is output to implement a range change to engage the determined operating range. The present invention also relates to a vehicle (5) and a related method of operating a vehicle control system (1).

An actual gear ratio change amount (Gr) is calculated by subtracting a pre-shift gear ratio (Gb) from an actual gear ratio (Gr). A gear ratio (G) is calculated by multiplying the actual gear ratio change amount (Gr) by a predetermined coefficient (C) and adding the product value to the pre-shift gear ratio (Gb). When the shift is an upshift, the gear ratio (G) is compared with aa target gear shift ratio (Ga), and the greater value is set as a virtual gear ratio (Gv). When the shift is a downshift, then the gear ratio (G) is compared with the target gear ratio (Ga) and the smaller value is set as the virtual gear ratio (Gv). A virtual input shaft rotational speed (Nv) is calculated by first dividing the actual gear ratio (Gr) by the virtual gear ratio (Gv) to obtain a quotient and by dividing the actual input shift rotational speed (Nr) by that quotient. A slip amount (S) is calculated by subtracting the actual input shaft rotational speed (Nr) of the automatic transmission (3) from the engine rotational speed (Ne). Finally, the engine rotational speed for display (Nd) is calculated by adding the slip amount (S) to the virtual input shaft rotational speed (Nv).

An equipment control apparatus for a vehicle has: a motor for vibrating that imparts, via a shift knob that contacts a vehicle occupant, vibrations as a stimulus that the vehicle occupant can feel by a somatic sensation; an electrostatic capacity sensor that detects electrostatic capacity as a state of contact of the vehicle occupant with the shift knob; and a control section that controls driving of the motor for vibrating so as to impart, to the vehicle occupant, vibrations of a strength that is determined in advance in accordance with the electrostatic capacity detected by the electrostatic capacity sensor.

A method for prompting bicycle gear shifting includes collecting cycling data of a user during cycling, comparing the collected cycling data with cycling data samples in a preset gear shifting strategy library including correspondence relationships between preset gear shifting strategies and the cycling data samples, and when the collected cycling data matches one of the cycling data samples in the gear shifting strategy library, outputting the gear shifting strategy corresponding to the cycling data sample to the user.

A change-gear transmission system includes a transmission that can be switched between multiple gears, a gearshift lever for selecting between the gears of the transmission, an automatically actuatable clutch, which is arranged in a drive train in series with the transmission and a control unit for automatically opening the clutch while maintaining a gear engaged in the transmission when a condition for the transition into coasting or gliding mode is fulfilled. The control unit is configured to detect a touch of the gearshift lever by the driver, to open the clutch only when no touch of the gearshift lever is detected, and further in the case that in the coasting or gliding mode, a touch of the gearshift lever is detected, to close the clutch while maintaining the engaged gear.

A hydraulic fracturing system includes an engine, transmission, and hydraulic fracturing pump. A driveshaft is coupled between the transmission and the hydraulic fracturing pump to transfer torque from the engine to the hydraulic fracturing pump. The hydraulic fracturing system also includes an advisory system including a display, a memory storing fuel consumption data and component durability data, and a controller. The controller is programmed to receive pump flow and pressure settings, identify an optimal transmission gear based on the pump flow and pressure settings, the fuel consumption data and the component durability data, and cause the optimal transmission gear to be displayed on the display.

A method for operating a motor vehicle, for which it is monitored whether a communication failure is present between a transmission control instrument of an automatic transmission of the motor vehicle, a selector lever control instrument of the automatic transmission, and/or a parking brake control instrument of an electronic parking brake of the motor vehicle, and/or whether, on account of a malfunction of the automatic transmission itself and/or on account of a malfunction of a selector lever itself for selection of drive stages of the automatic transmission, a parking position of the automatic transmission cannot be engaged.

A speed control system for automatically controlling the speed of a vehicle. The system operates according to a method that includes: causing automatically a vehicle to travel at a predetermined speed value at least in part by controlling an amount of torque applied to one or more wheels of a vehicle; determining a recommended transmission gear ratio for a transmission of the powertrain at a given moment in time; providing an indication of the recommended transmission gear ratio to a user; and receiving a clutch actuation signal indicative of an actuation state of a clutch that is configured to connect the transmission to a torque drive source. The system is configured automatically to control a speed of the torque drive source to achieve a speed determined in dependence at least in part on at least one predetermined parameter when a predetermined one or more conditions are met,

An actual gear ratio change amount (?Gr) is calculated by subtracting a pre-shift gear ratio (Gb) from an actual gear ratio (Gr). A gear ratio (G) is calculated by multiplying the actual gear ratio change amount (?Gr) by a predetermined coefficient (C) and adding the product value to the pre-shift gear ratio (Gb). When the shift is an upshift, the gear ratio (G) is compared with aa target gear shift ratio (Ga), and the greater value is set as a virtual gear ratio (Gv). When the shift is a downshift, then the gear ratio (G) is compared with the target gear ratio (Ga) and the smaller value is set as the virtual gear ratio (Gv). A virtual input shaft rotational speed (Nv) is calculated by first dividing the actual gear ratio (Gr) by the virtual gear ratio (Gv) to obtain a quotient and by dividing the actual input shift rotational speed (Nr) by that quotient. A slip amount (S) is calculated by subtracting the actual input shaft rotational speed (Nr) of the automatic transmission (3) from the engine rotational speed (Ne). Finally, the engine rotational speed for display (Nd) is calculated by adding the slip amount (S) to the virtual input shaft rotational speed (Nv).
