Problems solved by technology

[0002] Especially in heavy-duty trucks and other transport vehicles with automatic or semi-automatic transmissions, it is a problem that the gearbox control (Getriebesteuerung) only detects the uphill or downhill when the motor vehicle is already going uphill or downhill. and select the corresponding driving class
The height change and likewise the direction change of the road section ahead of the vehicle should be detected by image evaluation, which requires relatively high technical effort

Embodiment Construction

[0019] exist figure 1 The block diagram shown in shows a device in a motor vehicle which is used, for example, to predetermine a suitable driving level for an automatic transmission. The components used in the exemplary embodiment shown include a distance sensor 1 , an inclination sensor 2 , an evaluation device 3 , a gearbox control 4 and a first data transmission device D1 and a second data transmission device D2 . Furthermore, the evaluation device 3 is connected to a display 5 for displaying information about the set driving level for the driver of the vehicle.

[0020] The transmission control 4 controls the automatic transmission 6 as a function of the driving operating parameters transmitted to the transmission control via the data transmission means D1 and D2 and as a function of the uphill or downhill of the driving route 7 ahead of the vehicle. The data transmission device D1 can be, for example, a device for adjusting a driving mode, for example for adjusting a ter...

Abstract

The invention relates to a method and a device for predetermining a suitable driving class, in particular to a route profile (A, B, C) for a driving route ( 7 ) which is located ahead of a motor vehicle ( 11 ) in the direction of travel. ) in the case of predetermining a suitable driving level of an automatic transmission (6) of a motor vehicle (11) and a device, wherein the measured values ​​in the motor vehicle (11) and in the motor vehicle ( 11) The distance between previously extended road surfaces (10), and from the measured distance a gradient value is obtained which is taken into account for determining the driving class.

Description

technical field [0001] The invention relates to a method for predetermining a suitable driving level of an automatic transmission of a motor vehicle and a device for carrying out the method. Background technique [0002] Especially in heavy-duty trucks and other transport vehicles with automatic or semi-automatic transmissions, it is a problem that the gearbox control (Getriebesteuerung) only detects the uphill or downhill when the motor vehicle is already going uphill or downhill. And select the corresponding driving class. In the case of a load-dependent adjustment of an automatic transmission, this can lead to a too late downshift into a suitable driving range, ie, when, for example, the engine power is no longer sufficient for the currently selected driving range. Shift to a lower gear. A too late detection of an uphill that requires a lower driving level then leads to a shifting error in the automatic transmission. In order to avoid this problem, the driver of the ve...
