Abstract

A system or method for managing devices (collectively “device management system”) is disclosed. The device management system uses a matrix, table or other data structure technique (collectively “data structure”) to configure the input parameter(s) for one or more devices. The data structure can be modified in a dynamic or static fashion to accommodate different device configurations and different device interactions. Use of the data structure can eliminate the need for multi-level “nested if” statements that are complex, deep, and difficult to modify without causing an unforeseen error. The data structure can encapsulate the hardware specific characteristics of the various devices so that the application software written for the various devices can be written independent of the hardware-specific characteristics of the devices. Thus, the data structure can act as an interface between hardware-specific characteristics relating to the various devices and various user interactions and other related factors.

Claims

1. A device management system, comprising:

a plurality of devices, wherein each said device is adapted to perform a device function, wherein each said device function is associated with an input parameter and an output parameter, wherein each said input parameter includes a range of potential input values, wherein each said output parameter includes a range of potential output values, wherein each said output parameter is determined by and associated with at least one said input parameter;

a plurality of configuration components, each said configuration component including an input matrix comprising said input values corresponding to said input parameters and a custom feature matrix comprising operating rules, wherein said input values are selected and set from said range of potential input values to result in a desired said output value within said range of potential output values according to said operating rules, wherein said input matrix is created through a software application; and

a plurality of vehicles, wherein said plurality of vehicles includes a first vehicle type and a second vehicle type, each said vehicle includes a configuration component, and each said custom feature matrix comprises substantially identical operating rules.

2. The system of claim 1, wherein said input matrix is modified through said software application.

3. The system of claim 1, wherein said plurality of devices include a plurality of programmable logic devices, and wherein said plurality of programmable logic devices are located on a vehicle.

4. The system of claim 3, wherein said vehicle includes only one said configuration component.

5. The system of claim 1, wherein said plurality of device functions includes at least two of:

a body control function, an engine control function, a transmission control function, a power seat function, a door function, an instrument cluster function, an environmental function, an overhead console function, and a power function.

6. The system of claim 5, wherein said plurality of device functions include a body control function, an engine control function, a transmission control function, a power seat function, a door function, an instrument cluster function, an environmental function, an overhead console function, and a power function.

7. The system of claim 1, wherein said configuration component further includes an output matrix.

8. The system of claim 7, wherein said input matrix, said output matrix, and said custom feature matrix are configured to replace a plurality of nested if statements in a plurality of programming code invoked to perform said device functions.

9. The system of claim 7, said custom feature matrix including a plurality of feature values, wherein said output values are stored in said output matrix, wherein said plurality of feature values are stored in said feature matrix, wherein said output values are generated from said corresponding input values in said input matrix and said corresponding feature values in said feature matrix.

10. The system of claim 7, wherein said input matrix and said output matrix are set dynamically.

11. The system of claim 7, wherein said feature matrix is a static feature table.

12. The system of claim 1, wherein said plurality of device functions includes a first device function and a second device function, wherein said plurality of input parameters includes a first input parameter corresponding to said first device function and a second input parameter corresponding to said second device function, wherein the setting of said first input parameter changes the range of potential input values for said second device function.

13. The system of claim 12, wherein said plurality of devices includes a first device and a second device, wherein said first device function is associated with said first device and wherein said second device function is associated with said second device.
