Definitions
- the invention relates to a method for data exchange between several participants by means of a data bus.
- bus system adapted to this application becomes another one, which is particularly suitable for audio and telecommunications scopes
- the invention has for its object to provide a method for data exchange between several participants using a data bus, which has a high performance despite a vehicle-specific varying number of participants.
- the electrical system structure according to the invention is modular and inexpensive. It enables basic components to be used in all vehicles across several model series from one manufacturer. The higher-quality vehicles can be equipped as required with additional components without being more expensive than comparable series systems.
- This data bus can be, for example, a data bus, as described in DE 19636441 A and DE 19636442 A.
- This data bus is characterized by a data rate of more than 5 Mbit / s and is suitable, for example, for passive safety systems that include airbags, belt tensioners, etc., as well as the associated sensors and actuators and their control units.
- control units are located at various points in the vehicle, e.g. in the area of the center tunnel and the B-pillars, also in the door or on the steering column. All of these control units are connected to the data bus, which is under very little load in normal situations, i.e. outside of a crash or violent misuse phase. The same applies to the utilization of the processors in the control units.
- these control units are also used for other functions. These functions belong to a different range of functions, for example body electronics and relate to, for example, light control, wiper control, central locking and window regulator control.
- the light control and the wiper control on the one hand and the central locking and the window lift control on the other are part of a sub-data bus, which has a sufficient response time due to the small number of participants (e.g. a control unit and 10 connected consumers in the light control) and also with a low data rate is functional, ie provides the connected subscribers with the required data quickly and securely or has them provided.
- the block diagram shown in the figure contains, among other things, a control unit module SGM and control units designated S1 to S4. Together, these components are part of a passive safety system and are connected by a faster data bus "Sl-Bus" with a data rate of 5Mbit / s, for example.
- Control devices marked with “K” are connected to these control devices, each of which is a sub-data bus K-Bus cluster 1, K-bus cluster 2, K-bus cluster 3, ...
- the sub-data buses are each coupled to the control units S1 to S4 and to the control unit module SGM.
- the components SGM and S1 to S4 thus contain the functions of the Safety system and the basic functions of body electronics.
- some control units K are identified separately with K1, K2 and K3 for the further explanations.
- control units SGM and S1 to S4 adapt the data of the sub data bus participants in their format to the data format of the faster data bus or convert the data from this format to the data format of the sub data bus. They also control the task of this data of the sub-data bus participants on the faster data bus or, conversely, forward the data of the participants of the other sub-data buses to the participants of their connected sub-data bus.
- the data of all sub-data bus participants and the participants of the faster data bus are provided with a unique identifier.
- the identifiers of the participants in the connected sub-data bus are stored in the respective control unit. i !
- the particular advantage of the data bus structure according to the invention is that the number of telegrams per sub-data bus is significantly less than in the case of a data bus with only one line and the waiting time until a possible bus access is small due to the small number of subscribers.
- the K-bus addresses in the overall system are unique.
- the corresponding K-bus telegrams are converted according to a fixed rule to bus telegrams of the faster data bus with the corresponding IDs.
- codable "mini gateway tables” then only implement the telegrams that are also required in the respective sub data bus. When "moving" a control device K from one sub-data bus to another, only these gateway tables then have to be recoded. The overall system behavior thus remains absolutely unchanged.
- K-bus telegram TK1 The transmission of a K-bus telegram TK1 from node K1 in K-bus cluster 1 to node K2 in K-bus cluster 2 is described as an example.
- K1 sends telegram TK1 on K-bus cluster 1, triggered z. B. by pressing a button.
- SGM receives TK1 and packs the telegram TK1 into the data field of an S1 bus telegram.
- All Sl-Bus participants receive TK1 in Sl-Bus format and look in their respective gateway tables to see whether TK1 should be translated to the associated K-Bus cluster.
- S1 unpacks TK1 from the Sl-Bus format and transmits TK1 to the K-Bus cluster 2.
- K2 receives TK1.
- K3 should receive TK1 instead of K2, only TK1 needs to be deleted from the gateway table of S1 and entered in the gateway table of S2.
