Definitions
- the present invention relates to a method for controlling an automatic transmission, in particular a powershift transmission, by means of an electronic transmission control.
- An automatic transmission for motor vehicles usually has a hydrodynamic converter, clutches, brakes, a hydraulic control unit and an electronic transmission control, the latter controlling the clutches and brakes in such a way, depending on certain input variables, that the clutch and brakes are controlled by a suitable clutch / brake Combination a corresponding gear or a translation is defined.
- the driver can choose from several automatic driving ranges and defined fixed gears (e.g. gears 1-3, 2-5, 3-6) to ensure that driving operations can be adapted to the terrain.
- defined fixed gears e.g. gears 1-3, 2-5, 3-6
- the upper gears should be available for road travel, whereby in most cases the lower gears are not required for starting off.
- Ge ⁇ terrain ride should as far as possible the lower gears are available, but should be avoided when driving downhill upshifts in the higher gears.
- the object of the present invention is to provide a method for controlling an automatic transmission, with which the respectively optimal gear ranges are provided and which suppresses upshifts in overrun mode.
- the electronic transmission control ensures that the automatic transmission is switched to the current starting gear in the forward driving direction V. Preselecting forward means that the driver presses a multifunction button on the travel switch and moves the travel switch with the printed button from position N m to position V.
- the electronic transmission control ensures that the automatic transmission is shifted into the speed-adapted reverse gear within the automatic driving range, the first to third reverse gears being engaged as standard (usually the first reverse gear when the vehicle is stationary).
- Preselecting backwards means that the driver presses the multifunction button on the driving switch and moves the driving switch from the position N m to the position R with the button pressed.
- the driver can also change the starting gear by moving the control switch sideways to the right (+) or left (-) and thereby shift up or down by one gear, so that instead of the one set as second gear Standard start gear the first or the third gear can be used for starting.
- the starting gear is shown to the driver on a display.
- the automatic transmission uses the electronic transmission control to select the optimum gear within the automatic driving range depending on the driving speed and load until the driver manually changes the driving range preselection.
- the travel range preselection can be changed by:
- the automatic transmission changes over to the manual mode and remains in it until the driver reactivates the automatic mode or switches the drive switch to the neutral position.
- the entire automatic range can be released by introducing the start-up gear function.
- shifting into gear the vehicle starts off in the starting gear engaged by the automatic transmission, after which the driver has access to the entire automatic driving range without manual intervention.
- the starting gear which by default is second or third gear depending on the application.
- the automatic transmission is automatically switched down to ensure optimal starting at all times. After a successful start, the transmission automatically switches to the optimum of all gears that the automatic transmission makes available, depending on vehicle speed and load.
- a z. B. provided on the torque converter load detection generates a signal that is supplied to the electronic transmission control and that ensures that when
- Overrun upshifts are suppressed, d. H. that unwanted upshifts are prevented when driving downhill or off-road, so that manual restriction of the automatic range is not necessary in these driving situations.
- the method according to the invention ensures that the driver's operation is limited to the preselection of the direction of travel and that the automatic transmission with the electronic transmission control enables the driver to intervene manually in the gear selection at any time if he desires or deems this necessary. After that no automatic switching more in the transmission until the automatic function is reactivated at the push of a button or until the driving switch is moved from the neutral position in the direction of forward or backward travel.
