Abstract

An electronic system for a vehicle includes first components for carrying out control tasks in response to operating sequences and second components that coordinate a cooperation of the components for carrying out control tasks. The first components carry out the control tasks by using operating functions and basis functions, wherein the system is constructed such that the basis functions are combined in a basis layer, and a system layer is superimposed on the basis functions, which includes at least two of the second components. At least one open interface of the system layer is provided for the operating functions, and the system layer links the basis functions to any and all operating functions, such that the operating functions can be interconnected and/or used in a modular fashion.

Claims

1. An electronic system for a vehicle comprising:

first components for carrying out control tasks through use of operating functions and basis functions in response to operating sequences;

second components coordinating a cooperation of the first components for carrying out the control tasks;

a basis layer containing the basis functions;

a system layer superimposed on the basis layer including at least two of the second components; and

at least one open interface between the system layer and the operating functions;

wherein the system layer links the basis functions to the operating functions such that the operating functions can be interconnected and used in a modular fashion.

2. The electronic system of claim 1, wherein functions that monitor the operating functions are additionally interconnected in the system layer.

3. The electronic system of claim 1, wherein the second components include components for regulating control tasks for at least one of an overall vehicle, vehicle motion, and a drive train, the system layer including at least one of components for an overall vehicle, a drive train and vehicle motion.

4. The electronic system of claim 1, wherein the operating functions are interconnected in a modular fashion at least one of:

before a compilation, during a compilation, before execution of the control tasks, and during execution of the control tasks.

5. A system layer of an electronic system of a vehicle comprising:

first components for carrying out control tasks in response to operating sequences of the vehicle, the first components carrying out the control tasks by using operating functions and basis functions; and

at least two second components for coordinating a cooperation of the first components for carrying out the control tasks; and

at least one open interface;

wherein the system layer links the operating functions to the basis functions via the least one open interface such that the operating functions can be at least one of linked in a modular fashion to the electronic system and interconnected to the electronic system.

6. The system layer of claim 5, wherein the system layer interconnects monitoring functions with the operating functions.

7. The system layer of claim 5, wherein the second components include components that coordinate a cooperation of the first components that control at least one of the overall vehicle, the drive train and vehicle motion.

8. A functional control system for a vehicle comprising:

a real time operating system;

a basis layer containing basis control functions superimposed on the real time operating system; and

a system layer superimposed on the basis layer;

an open interface coupled to the system layer; and

operating functions that can be added and removed from the open interface in a modular fashion.

9. The functional control system of 8, wherein the basis control functions include system core functions and a driver functions.
