Abstract

A vehicle control software includes control data serving as information for controlling a vehicle; a public side software component serving as a software component for laying open the control data; a plurality of reference side software components each serving as a software component for referring to the control data; and data conversion software for converting a data format when transferring the control data between the public side software component and each of the reference side software components. In this vehicle control software, the data conversion software is subjected to an activate request at a predetermined timing, makes a reference request of the public side software component, and converts the acquired control data into a data format to which the public side software component refers.

Claims

1. A vehicle control software comprising:

control data serving as information for controlling a vehicle;

a public side software component serving as a software component for laying open the control data;

a plurality of reference side software components serving as a software component for referring to the control data; and

data conversion software for converting a data format when transferring the control data between the public side software component and each of the reference side software components,

wherein the data conversion software is subjected to an activate request at a predetermined timing, makes a reference request of the public side software component, and converts the acquired control data into a data format to which the public side software component refers.

2. The vehicle control software according to claim 1,

wherein the data conversion software stores the converted control data as reference data;

and

wherein each of the reference side software components refers to the reference data.

3. The vehicle control software according to claim 1, wherein the data conversion software transfers the converted control data to each of the reference side software components, using data request command prepared by each of the reference side software components.

4. The vehicle control software according to claim 1, wherein the data format converted when the control data is transferred between the public side software component and each of the reference side software components, is at least either one of a variable name and a unit of variable.

5. The vehicle control software according to claim 1, wherein the timing at which the data conversion software is subjected to an activate request is set independently of the timing at which each of the reference side software components is subjected to an activate request.

6. The vehicle control software according to claim 1, wherein the timing at which the data conversion software is subjected to an activate request is set independently of the timing at which the public side software component is subjected to an activate request.

7. The vehicle control software according to claim 1, wherein the timing at which the data conversion software is subjected to an activate request, is at least either one of a time period or an interrupt signal.

8. The vehicle control software according to claim 1, wherein the software component comprises:

a basic software component for controlling an electronic vehicle control apparatus equipped with vehicle control software, sensors, and actuators; and

a control application component for controlling the state of an object to be controlled, using the basic software component.

9. The vehicle control software according to claim 8, wherein the control data is converted by the data conversion software when the data is laid open and referred to between the basic software component and the control application component.

10. The vehicle control software according to claim 1, wherein the software component is a component that lays open the control data and that refers to the control data.

11. The vehicle control software according to claim 1, wherein the software component has an interface that clearly specifies the distinction between the public data and reference request data.

12. The vehicle control software according to claim 1, wherein the data conversion software refers to the distinction between the public data and the reference request data, the distinction being clearly specified by the software component.

13. A vehicle control apparatus for controlling a vehicle using a microcomputer, the apparatus comprising the software as recited in claim 1.
