Embodiment Construction

[0036]The synergy of drive motor and automatic transmission is known from, for example, DE 198 02 736 A1.

[0037] 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.

[0038] 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.

[0039] The data exchange between the controller EDC and the controller TCU takes place via a large number of data and / or signals already def...

Abstract

The method involves supplying data and / or signals to a controller of an automated gearbox (3) over an interface i.e. controller area network (CAN)interface according to SAE 1939-71. A temporally provident incidental course of drive motor torque for a defined event is transmitted to the controller during occurrence of the event so that a gearbox switching strategy is determined and / or provided based on the transmitted course of torque. A start-up process, upshift or shift-back of the gearbox, push-pull operation and towing operation are considered as the event. Independent claims are also included for the following: (1) a device for controlling an automated gearbox of a commercial motor vehicle (2) a test stand for a drive motor of a vehicle.

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 used regularly. 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 a 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 is...
