IPC: B60W10/101
Filed: 1999-03-02
Abstract: PROBLEM TO BE SOLVED: To secure the optimum cooperation in order to attain a desired purpose despite the trade-off relation confirmed between the optimization results by optimizing a control module used for the normal control and then optimize another control module used for the normal control to improve or maintain the acquired characteristic. SOLUTION: When plural controlled systems exist and every control module is optimized, an optimization processing part is prepared for every control module that is evolved. Under such conditions, some characteristic changes are affected with each other according to the relation of the controlled systems and a characteristic optimization is sometimes traded off. In such a case, the cooperative optimization processing is secured among plural control modules. For example, after one control module is optimized, another control module is optimized so as to improve or maintain the acquired characteristic. Thus, it's possible to optimize the characteristic of another controlled system in the optimum characteristic range of one controlled system.
