Description

The The invention relates to an electronically controlled assembly according to The preamble of claim 1. Furthermore, the invention relates to a system with such an assembly. Finally, the invention relates a method for preparing and mounting such System.

A Such assembly is known by public prior use. The learning of the control device takes place in some of these modules the factory mounting of the module. This requires that the Control device also during the Installation of the assembly in the installation environment can not be removed may otherwise lose the training data values. For others Previously known assemblies are taught on-site, so only then, if the module is already mounted at the installation site. This is expensive because the learning then not central factory but decentralized must be done.

It It is an object of the present invention to provide an assembly of the the aforementioned type and an electronically controlled system with such an assembly in such a way that the preparation and assembly of the assembly is simplified.

These The object is achieved by an electronically controlled module with the identification part of claim 1 features and by a system according to Claim 5.

According to the invention was realized that it was to facilitate the preparatory learning the module is sufficient, a memory connected to the unit for the Provide training data values. Thus, a factory-prepared Learning the module possible, without them being final with a control unit be equipped got to. Therefore, not only the preparation is easier, but also the subsequent assembly of the module at the installation, since the Control unit later, so after this installation, can be attached.

memory types according to the claims Figures 2 to 4 are well adapted to the requirements of a store for teach-in data values when learning the electronically controlled module suitable. The programmable memory types can be advantageous to the respective memory task be adjusted.

The Advantages of the electronically controlled system according to claim 5 correspond those related to the electronically controlled Assembly executed were.

One Backup memory according to claim 6 provides the possibility of learning data values from the memory to take the aggregate / storage unit into the backup storage. In case of a failure the memory of the unit / storage unit can then easily exchanged, with the teach-in data values of Backup memory back be transferred to the memory of the aggregate / storage unit. An outage Therefore, the memory of the aggregate / memory unit does not lead to the need a re-learning.

A Another object of the invention is to provide a method of preparation and assembly of the system according to the invention to specify, which leads to a simplified preparation and assembly of the system leads.

These The object is achieved by a method having the features specified in claim 7.

The Advantages of this procedure correspond to those already mentioned above Related to the assembly and the system.

The Advantages of the method according to claim 8 correspond to those of the system according to claim 6.

A electronically controlled assembly of the type mentioned is known by public prior use.

One embodiment The invention will be explained in more detail with reference to the drawing. In show this:

1 a schematically electronically controlled system having an electronically controlled assembly and a controller;

2 the electronically controlled assembly after 1 in which a learning module is used instead of the control unit; and

3 the module after 1 So the system without the controller.

1 shows an electronically controlled system denoted overall by 1. The system 1 has an electronically controlled assembly 2 , which separately in 3 is shown. The assembly 2 has a controlled aggregate 3 , These are the Example with a dual-clutch transmission. The aggregate 3 has electronically controlled components not shown in detail in the schematic diagram.

Part of a control device 4 for the aggregate 3 is a store 5 , At the store 5 It can be an EEPROM (Electrically Erasable Programmable Read-Only Memory) memory, a flash memory, or an OTP (on time programmable) memory.

The memory 5 and the aggregate 3 are connected to a common to be assembled unit / storage unit, which in the illustrated embodiment with the assembly 2 matches. Alternatively, it is possible that the aggregate / storage unit only parts of the unit 3 , that is, the electronically controlled components to be taught-in, so that then the aggregate / memory unit is not identical to the assembly 2 ,

The memory 5 has an interface 6 for data connection of the aggregate / storage unit 2 with a control unit 7 , which together with the memory 5 the controller 4 forms. The control unit 7 has an internal backup memory 8th on.

Together with the control unit 7 forms the assembly 2 the electronically controlled system 1 ,

The preparation and installation of the system 1 goes as follows:
First, the aggregate / storage unit 2 with the help of a 2 schematically illustrated teaching module 9 learned. This process step is also known as teach-in. The teach-in module is via the interface during this teaching step 6 with the memory 5 the aggregate / storage unit 2 connected. During teach-in, the unit is put into various preselected operating states and, based on the reactions of the unit, training data values, for example gear shifting paths or clutch characteristics, are determined. These training data values are then read by the learning module 9 in the store 5 the aggregate / storage unit 2 stored. Subsequently, the learning module 9 from the aggregate / storage unit 2 separated. The teach-in data remains in memory 5 saved. The aggregate / storage unit 2 or the module 2 is then mounted at a mounting location. The relatively compact module is mounted in this step 2 without the control unit 7 , Subsequently, the control unit 7 over the interface 6 with the aggregate / storage unit 2 connected. The electronically controlled system 1 is then ready for use. A teach-in of the controller 7 eliminated.

For safety reasons, after connecting the controller 7 with the aggregate / storage unit 2 a transmission of the training data values from the memory of the aggregate / memory unit 2 in the backup memory 8th respectively. Should the memory 5 the aggregate / storage unit 2 fail in later operation, it is then possible in the backup memory 8th stored training data values in a swapped memory 5 the aggregate / storage unit 2 without having to re-teach.

In case of a defect of the control unit 7 This can easily be replaced and against a new control unit 7 change. Again, no new learning step is required.
