Control system for motor vehicles
First Claim
1. A control system for a motor vehicle having a plurality of functional subsystems, each including a plurality of control devices, and a central databus, wherein:
- control devices of different subsystems are combined to form local modules, according to their spatial arrangement in the vehicle;
the control devices within a module are connected to one another via a module bus; and
each module bus is connected to the central databus via a module interface.

Abstract
In a control system for motor vehicles having a plurality of functional subsystems, such as a passenger compartment controller, a telematics system, a drive controller and a chassis controller, each functional subsystem has a plurality of control devices, and a central databus. Control devices of different subsystems are combined, in accordance with their spatial arrangement in the vehicle, to form local modules and are connected to one another by means of a module bus. Each module bus is connected to the central databus by means of a module interface.

10. A control system for a vehicle, comprising:
-
a plurality of control subsystems, each having a plurality of controllers for vehicle components, said controllers being situated at diverse locations in the vehicle; and
a central databus;
wherein,said controllers are grouped and incorporated into a second plurality of local modules, based on their location in the vehicle, each such module including controllers of different subsystems, that are situated within a particular vehicle location;
each local module includes a local module databus for communication between controllers in the local module;
each local module includes a module interface coupled to the local module databus; and
each module interface is connected to the central databus, whereby controllers of every control subsystem can communicate with other controllers of other subsystems. - View Dependent Claims (11, 12)

13. A method for controlling components in vehicle subsystems in a vehicle having a plurality of subsystems, each of which subsystem includes a plurality of controllers situated of dispersed locations within the vehicle, said method comprising:
-
grouping said controllers according to their location within the vehicle, and combining controllers of each group to form a local module, each such module including controllers from different subsystems that are situated within a particular vehicle location;
communicating among controllers within a particular module via a module databus;
coupling each module databus to a central databus via a module interface, whereby each controller can communicate with other controllers via the central databus. - View Dependent Claims (14, 15)
