Abstract

To eliminate the need for additional operating elements for fine tuning the management of the engine and transmission of a mobile agricultural vehicle, the electronic transmission-control unit is connected via an ISO bus to the ISO bus terminal, such that current transmission data can be displayed in the cabin of the vehicle and adjustments can be made via the ISO bus terminal to modify this transmission data.

Claims

1. A mobile agricultural vehicle comprising:

a CAN bus facilitating an exchange of data and information within the vehicle;

an ISO bus;

a single display unit connected to the ISO bus;

a transmission electronic control unit being connected to the single display unit, via the ISO bus, so that transmission data stored in the transmission electronic control unit can be displayed on the single display unit;

the transmission data consisting of a current speed of a transmission drive input, current speeds of transmission drive outputs and current speeds of hydrostats;

the single display unit displaying current gearbox transmission ratios, oil-change intervals, residual life of components, and fault messages derived from the transmission control unit;

the single display unit functioning as an ISO bus terminal and including direct input means, via a touch-screen function, and at least one push-button and at least one induction regulator both being arranged adjacent the touch-screen;

the single display unit including a serial interface for uploading both new programs and upgrades of the transmission control system, via the ISO bus, to the transmission electronic control unit of the transmission;

at least one induction regulator functioning as a compression potentiometer for the transmission electronic control unit;

at least one induction regulator for controlling a magnitude of the speed;

at least one push-button for calibrating the control system; and

the touch-screen facilitating inputting codes for independently initiating special transmission functions;

the single display unit facilitating control of both the vehicle and the at least one mounted implement, by a mobile agricultural vehicle driver, by using a single display and control unit.

2. The mobile agricultural vehicle according to claim 1, wherein an intended speed is inputted by the input means to the single display unit.

3. The mobile agricultural vehicle according to claim 2, wherein a combustion engine pressure setting is inputted by the input means to the single display unit.

4. The mobile agricultural vehicle according to claim 3, wherein a combustion engine calibration is inputted by the input means to the single display unit.

5. The mobile agricultural vehicle according to claim 4, wherein the transmission is a power-branched hydrostatic-mechanical transmission.

6. The mobile agricultural vehicle according to claim 5, wherein the transmission electronic control unit is connected directly to the single display unit via the CAN bus and a bridge-ECU.

7. The mobile agricultural vehicle according to claim 6, wherein the single display unit includes a serial interface through which programs are transferred to the transmission electronic control unit.
