Abstract

A control system of a vehicle is suggested, which has several components (10 to 1014), which are arranged in different logical levels with at least one coordination component (14), which monitors the making available of power and the power requirement of at least one type of resource which is needed by at least two consumers, and with at least one component (101, 1011-1013) which makes the resource available, with at least two components (10, 12 ) which consume the resource; coordination components and consuming components are arranged in one logical level, characterized in that the component, which makes available the resource, is arranged in a subordinated level of a consuming component (10, 12) and the coordination component (14) inquires of the component, which makes available the resource, as to its power capacity with respect to the resource.

Claims

1. A control system of a vehicle, comprising:

several components (10 to 1014) arranged in different logical levels;

said several components (10 to 1014) including a coordinator (14) for the entire vehicle, which monitors the need and the making available of resources required throughout the vehicle;

said several components (10 to 1014) further including additional components (10, 12) with at least one of said additional components (10, 12) including a coordinator (104) which administers the resources needed in those additional components (10, 12) and which communicates with said coordinator (14) for the entire vehicle and components (101 to 103) of the next level of said additional components (10, 12); and

,

said components (101 to 103) of said next logical level including sources and consumers of said resources generated by said source.

2. The control system of claim 1, wherein the coordinator (14) is arranged in an uppermost logical level for the total vehicle and the additional components (10, 12), which consume the resources, are components for controlling the vehicle motion and for controlling the chassis and the interior.

3. The control system of claim 2, wherein the component, which makes available the resource, is an engine-transmission unit as source of mechanical power of the vehicle system, which is arranged within the logic level “

drive/brake”

of the component for controlling the vehicle motion.

4. The control system of claim 3, wherein the coordinator (14) inquires of all of said additional components (10, 12) of its detailing level as to their actual requirement of the resource (PV_Des, PNA_Des).

5. The control system of claim 4, wherein the coordinator determines a maximum permissible consumption (PV_max, PNA_max) of the resource from the power requirement for each component of its detailing level.

6. The control system of claim 5, wherein the components inquire as to this value.

7. The control system of claim 1, wherein each component is provided with a coordinator which emits orders to the component making available the resource for making available the resource in dependence upon the maximum permissible consumption.

8. The control system of claim 7, wherein the resource is the mechanical power, the values pregiven or inquired by the coordinator are power values and the order represents a torque value.
