Abstract

An integrated control system includes processes A-C in which request acceleration, target gear ratio, and target engine revolution are calculated in accordance with the HMI in a main control system (accelerator) controlling the driving system, and processes D-F in which the request acceleration, target gear ratio, and target engine revolution are calculated in accordance with a manual manipulation request where the driver upshifts or downshifts the gear of the transmission, for example, that is an actuator.

Claims

1. A vehicle integrated control system comprises a plurality of control units operating autonomously for controlling a running state of the vehicle based on a manipulation request,

wherein each control unit comprises

a sensing unit for sensing a request of a driver, and

a controller for controlling said vehicle by generating a control target based on a request, and manipulating an actuator set in correspondence with each unit, using said control target,

said system further comprising

a processing unit generating information to be used to accommodate a direct request towards said actuator by said driver, said information being priority information used in priority over a control target generated at said controller, and providing the generated information to each said control unit.

2. The vehicle integrated control system according to claim 1, wherein said processing unit includes a generation unit generating said priority information based on environmental information around said vehicle and said direct request.

3. The vehicle integrated control system according to claim 2, wherein said environmental information includes information related to a road on which said vehicle runs.

4. The vehicle integrated control system according to claim 2, wherein said environmental information includes information related to another vehicle in a neighborhood of said vehicle.

5. The vehicle integrated control system according to claim 1, wherein each said controller generates a control target based on said request even when the vehicle is under integrated control with said priority information used at each control unit.

11. The vehicle integrated control system according to claim 2, wherein each said controller generates a control target based on said request even when the vehicle is under integrated control with said priority information used at each control unit.

12. The vehicle integrated control system according to claim 3, wherein each said controller generates a control target based on said request even when the vehicle is under integrated control with said priority information used at each control unit.

13. The vehicle integrated control system according to claim 4, wherein each said controller generates a control target based on said request even when the vehicle is under integrated control with said priority information used at each control unit.

6. A vehicle integrated control system comprises a plurality of control units operating autonomously for controlling a running state of the vehicle based on a manipulation request,

wherein each control unit comprises

sensing means for sensing a request of a driver, and

controller means for controlling said vehicle by generating a control target based on a request, and manipulating an actuator set in correspondence with each unit, using said control target,

said system further comprising

a processing unit generating information to be used to accommodate a direct request towards said actuator by said driver, said information being priority information used in priority over a control target generated at said controller means, and providing the generated information to each said control unit.

7. The vehicle integrated control system according to claim 6, wherein said processing unit includes means for generating said priority information based on environmental information around said vehicle and said direct request.

8. The vehicle integrated control system according to claim 7, wherein said environmental information includes information related to a road on which said vehicle runs.

9. The vehicle integrated control system according to claim 7, wherein said environmental information includes information related to another vehicle in a neighborhood of said vehicle.

10. The vehicle integrated control system according to claim 6, wherein each said controller means comprises means for generating a control target based on said request even when the vehicle is under integrated control with said priority information used at each control unit.

14. The vehicle integrated control system according to claim 7, wherein each said controller means comprises means for generating a control target based on said request even when the vehicle is under integrated control with said priority information used at each control unit.

15. The vehicle integrated control system according to claim 8, wherein each said controller means comprises means for generating a control target based on said request even when the vehicle is under integrated control with said priority information used at each control unit.

16. The vehicle integrated control system according to claim 9, wherein each said controller means comprises means for generating a control target based on said request even when the vehicle is under integrated control with said priority information used at each control unit.
