Abstract

A control target processing system includes: a first generating unit that generates first time-series data that are time-series data of an input value; a second generating unit that is formed of a plurality of processing units, that exchanges time-series data among the plurality of processing units, and that calculates intermediate computation values corresponding to the respective input values contained in the input time-series data in the respective processing units to thereby generate second time-series data that are time-series data of the intermediate computation value; a selecting unit that selects a selection value from among the second time-series data in accordance with a first selection condition; and an output unit that calculates and outputs a control variable for controlling a controlled object on the basis of the selection value.

Claims

1. A control target processing system comprising:

a first generating unit that generates first time-series data that are time-series data of an input value;

a second generating unit that is formed of a plurality of processing units, that exchanges time-series data among the plurality of processing units, and that calculates intermediate computation values corresponding to the respective input values contained in the first time-series data through predetermined processes in the respective processing units to thereby generate second time-series data that are time-series data of the intermediate computation value;

a selecting unit that selects a selection value from among the second time-series data in accordance with a first selection condition; and

an output unit that calculates a control variable for controlling a controlled object on the basis of the selection value and then outputs the control variable as a control target.

2. The control target processing system according to claim 1, wherein

the first generating unit estimates a future input value and generates the first time-series data containing the future input value.

3. The control target processing system according to claim 1, wherein

the first generating unit generates a plurality of pieces of first time-series data that temporally partially overlap, and

the second generating unit generates a plurality of pieces of second time-series data corresponding to the respective pieces of first time-series data.

4. The control target processing system according to claim 1, wherein

the first selection condition is set on the basis of a time at which the selection value is selected.

5. The control target processing system according to claim 1, wherein

the first generating unit generates a plurality of types of first time-series data corresponding to a plurality of types of input value,

the second generating unit generates a plurality of types of second time-series data on the basis of the plurality of types of first time-series data,

the selecting unit selects selectable data ranges from among the respective types of second time-series data in accordance with a second selection condition, and

the output unit calculates the control variable from intermediate computation values contained in the respective selectable data ranges.

6. The control target processing system according to claim 5, wherein

an input value of a predetermined type is input to the output unit, and

the output unit calculates the control variable on the basis of intermediate computation values contained in the respective selectable data ranges and the input value of the predetermined type.

7. The control target processing system according to claim 5, wherein

the second selection condition is set on the basis of a processing period of time of the respective types of second time-series data.

8. The control target processing system according to claim 1, wherein

the first generating unit generates the first time-series data having a time length set on the basis of a processing period of time.

9. The control target processing system according to claim 8, wherein

in the second generating unit, each of the processing units outputs the time-series data, having a time length set on the basis of a processing period of time of a subsequent one of the processing units, to the subsequent one of the processing units.

10. The control target processing system according to claim 9, wherein

the second generating unit outputs the second time-series data, having a time length set on the basis of a processing period of time of the output unit, to the output unit.

11. The control target processing system according to claim 8, wherein

the processing period of time includes a processing delay time.

12. The control target processing system according to claim 1, further comprising:

a calculation unit that calculates a control timing at which the controlled object is controlled in accordance with the control variable, wherein

the output unit outputs the control target on the basis of the control timing.

13. The control target processing system according to claim 1, wherein

the input value is a value detected by a sensor equipped for a vehicle, the intermediate computation value is a value regarding a driving target of the vehicle, and

the control variable is a control variable for at least any one of an engine, a brake and a steering.
