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 apparatus comprising:

a public side software component for laying open control data which is information used for controlling a vehicle;

a plurality of reference side software components for referring to the control data;

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

a data storage used for executing a vehicle control software having the public side software component, the plurality of reference side software components and the data conversion software in order to transfer the control data between the public side software component and the plurality of reference side software components,

wherein the data conversion software converts the control data obtained from the public side software component into a plurality of reference data corresponding to periods for activating the plurality of reference side software components, storing the plurality of reference data in the data storage.

2. The vehicle control apparatus according to claim 1, wherein the data conversion software is activated at timings different from the timings for activating the plurality of reference side software components.

3. The vehicle control apparatus according to claim 1, wherein the data conversion software is activated at timing different from the timing for activating the public side software component.

4. The vehicle control apparatus according to claim 1, wherein

the data conversion software instructs the vehicle control apparatus to execute a step for storing the converted control data in the data storage as a reference data,

the plurality of reference side software components instructing the vehicle control apparatus to execute a step for referring the reference data.

5. The vehicle control apparatus according to claim 1, wherein

the data conversion software instructs the vehicle control apparatus to execute a step for transferring the converted control data to the reference side software components by using data request command prepared by the reference side software components.

6. The vehicle control apparatus according to claim 1, wherein

the data format converted when the control data is transferred between the public side software component and the reference side software components, is at least one of a variable name and a unit of variable.

7. The vehicle control apparatus according to claim 1, wherein

the vehicle control apparatus activates the data conversion software by using at least either one of a time period or an interrupt signal.

8. The vehicle control apparatus according to claim 1, wherein

each of the public side software component and the reference side software component comprises:

a basic software component for controlling the vehicle control apparatus, sensors, and actuators; and

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

9. The vehicle control apparatus according to claim 8, wherein

the data conversion software makes the vehicle control apparatus to execute a step for converting the control data when the data is laid open and referred to between the basic software component and the control application component.

10. The vehicle control apparatus according to claim 1, wherein

at least either one of the public side software component or the reference side software component makes the vehicle control apparatus to execute a step for laying open the control data and for referring the control data.

11. The vehicle control apparatus according to claim 1, wherein

each of the public side software component and the reference side software component comprises:

an input and output interface clearly specifies a distinction between a public data and the reference data.

12. The vehicle control apparatus according to claim 11, wherein

the data conversion software makes the vehicle control apparatus to execute a step for referring the distinction between the public data and the reference data.

13. The vehicle control apparatus according to claim 1, further comprising:

an IO framework software used for controlling an execution flow of the data conversion software;

an application framework software used for controlling an execution flow of the public side software component and the reference side software components; and

a task framework software used for activating the IO framework software and the application framework software,

wherein the vehicle control apparatus executes the IO framework software, the application framework software, and the task framework software.
