Automobile function module circuit

摘要

The invention concerns a circuit arrangement especially for functional modules that can be connected and arranged in a vehicle with a voltage supply and/or a control circuit, where the functional modules are connected via at least two bus systems with a common gateway, which is effected via a central unit. The central unit (12) has a central electricity module (14) and a driver information module (16), a first bus system (20) is connected to the driver information module (16), a second bus system (26) is connected to the central electricity module (14), and the gateway comprises a combination of microprocessor units (24) and (30) arranged respectively in the driver information module (16) and the central electricity module (14), and these are connected with one another via an interface (32) for the exchange of data.
