Embodiment Construction

[0037] The synergy of drive motor and automatic gearbox is known from eg DE 19802736A1.

[0038] in addition, figure 1 The drawing shows a commercial vehicle as a whole, comprising an engine 1 , a clutch 2 , an automatic transmission 3 , a cardan shaft 4 , a main drive 5 and a hub drive 6 as drive train components.

[0039] In this case, a controller EDC is arranged in the engine 1 and a controller TCU is arranged in the transmission 3 including the clutch 2 . A vehicle control computer FFR placed in between is connected with the controller EDC and the controller TCU through the network CAN, such as figure 2 shown. other in figure 2 The inserted, unnamed blocks shown in dotted lines describe examples of other equipment of the commercial vehicle, but these are not relevant for further explanation of the invention.

[0040] The data exchange between the control unit EDC and the control unit TCU takes place via a large number of data and / or signals that have been establishe...

Abstract

A method for actuating an automated transmission, in particular an automated transmission of a commercial vehicle, which is coupled to a drive motor, where data and / or signals are supplied to a controller of the automated transmission via an interface. When a defined event occurs, a temporally predictive non-steady profile of the drive motor torque for this event is transmitted to the controller of the automated transmission. The transmission controller ascertains and / or specifies a transmission shifting strategy on the basis of the transmitted data. There is also provided an apparatus for actuating an automated transmission, and also a test bench.

Description

technical field [0001] The invention relates to a method for triggering an automatic transmission, in particular an automatic transmission for commercial vehicles. Furthermore, the invention also relates to a device for triggering an automatic transmission, in particular an automatic transmission for commercial vehicles. In addition, the invention also includes a test stand suitable for a propulsion engine, in particular a propulsion engine of a commercial vehicle. Background technique [0002] To test newly developed drive engines, such as diesel engines, dynamometers are regularly used. Representative operating conditions of the drive engine can be simulated and analyzed by one such dynamometer. As a result, test activities on certain roads can be carried out on the test bench. [0003] Before the new drive engine is finally put into series use, it is additionally necessary to test and optimize the compatibility of the drive engine with the automatic transmission, which...
