Abstract

The present invention provides a vehicle control device and a vehicle control simulation device that enable, even for parallel processing with a plurality of arithmetic devices, approximation in act between at verification of simulation operation on a model base and at verification of operation on an actual vehicle. Provided are: control model information for control of a system; hardware information for operation of a control model; arithmetic-device allocation information as to which arithmetic device in hardware is allocated to perform arithmetic processing to a control program in the control model; delay time information regarding a case where the control model operates on the hardware; and a delay-time adding unit configured to create delay-inclusive control model information in which the delay time information is inserted in the control model, based on at least either the arithmetic-device allocation information or the hardware information.

Claims (17)

1. A vehicle control device comprising:

control model information for control of a system;

hardware information for operation of a control model;

arithmetic-device allocation information as to which arithmetic device in hardware is allocated to perform arithmetic processing to a control program in the control model;

delay time information regarding a case where the control model operates on hardware; and

a delay-time adding unit configured to create delay-inclusive control model information in which the delay time information is inserted in the control model, based on at least either the arithmetic-device allocation information or the hardware information.

2. The vehicle control device according to claim 1 , wherein the delay-time adding unit inserts the delay time information, among combinations of functional blocks in the control model, into a combination of functional blocks in which the respective allocated arithmetic devices are different, based on at least the arithmetic-device allocation information and the hardware information.

3. The vehicle control device according to claim 1 , wherein the hardware information includes at least either information regarding a plurality of system controller units or information regarding a communication line through which a storage device and the system controller units are connected.

4. The vehicle control device according to claim 1 , wherein the hardware information includes at least either information regarding a plurality of processor cores or information regarding a communication line through which a storage device and the processor cores are connected.

5. The vehicle control device according to claim 1 , wherein the delay time information includes at least either information regarding time necessary for synchronous processing between a plurality of arithmetic devices or information regarding time necessary for data communication between a plurality of arithmetic devices.

6. The vehicle control device according to claim 1 , wherein the delay time information is probability distribution information regarding delay time in a case where the control model operates on the hardware a plurality of times.

7. A vehicle control simulation device comprising:

control model information for control of a system;

hardware information for operation of a control model;

arithmetic-device allocation information as to which arithmetic device in hardware is allocated to perform arithmetic processing to a control program in the control model;

delay time information regarding a case where the control model operates on the hardware; and

a delay-time adding unit configured to create delay-inclusive control model information in which the delay time information is inserted in the control model, based on at least either the arithmetic-device allocation information or the hardware information.
