Abstract

A system and a method for controlling or regulating the operational sequences in a vehicle using a number of control units, which are each connected to a communications bus. A central data management unit, on its part, is connected to the communications bus and is designed in such a way that it makes available to the control units, respectively, specific data from a permanent memory. This makes it possible to save having permanent memories in the individual controllers for supplying configuration data of the control units, whereby operating security is increased and expenditure is decreased.

Claims

1. A system for controlling or regulating operational sequences in a vehicle, comprising:

a communications bus;

a plurality of control units, connected to the communications bus; and

a central data management unit which, on its part, is connected to the communications bus, the central data management unit including a permanent memory, the central data management unit making available to the control units, respectively, specific data from the permanent memory.

2. The system according to claim 1, wherein the central data management unit stores the specific data of the control units.

3. The system according to claim 1, wherein the central data management unit itself represents one of (a) a control unit and (b) an addition to a control unit present in the vehicle.

4. The system according to claim 1, wherein the communications bus is a serial data bus.

5. A method for controlling or regulating operational sequences in a vehicle using a plurality of control units, which are each connected to a communications bus, the method comprising:

permanently storing specific data associated with at least one respective control unit in a central data management unit that is connected to the communications bus; and

making available the specific data to the respective control unit as required.

6. The method according to claim 5, wherein specific data of each of the control units are stored in the central data management unit.

7. The method according to claim 5, further comprising loading the data made available by the central data management unit into a volatile memory of the control unit.

8. The method according to claim 5, further comprising respectively assigning a virtual address space in a memory of the data management unit to the control units for a utilization of a permanent memory of the central data management unit.

9. The method according to claim 5, further comprising using at least one of (a) transport protocols, (b) diagnosis protocols and (c) bus drivers, that are available in the vehicle, for communications between the control units and the data management unit via the communications bus.

10. The method according to claim 5, further comprising, in case of an interruption of communications via the communications bus, operating the control units using preset parameters in an emergency mode.

11. The method according to claim 5, further comprising transmitting the data from the central data management unit required for bringing up a system directly to the respective control unit via the communications bus.
