Abstract
A control apparatus for an exhaust gas recirculation valve is disclosed. The exhaust gas recirculation valve is provided in an exhaust gas recirculation pipe for recirculating exhaust gases from an internal combustion engine to an intake system of the engine. The exhaust gas recirculation valve controls an exhaust gas recirculation amount. An opening of the exhaust gas recirculation valve is controlled to a target opening, based on a controlled object model which is obtained by modeling the exhaust gas recirculation valve.
Claims20
A control apparatus for an exhaust gas recirculation valve which is provided in an exhaust gas recirculation pipe for recirculating exhaust gases from an internal combustion engine to an intake system of said engine, said exhaust gas recirculation valve controlling an exhaust gas recirculation amount, said control apparatus comprising:
- input means for receiving data regarding an operational parameter of said internal combustion engine;
- output means for outputting a control signal;
- and
- control means for controlling an opening of said exhaust gas recirculation valve via said control signal to a target opening based on a controlled object model which is obtained by modeling said exhaust gas recirculation valve.
A control method for an exhaust gas recirculation valve which is provided in an exhaust gas recirculation pipe for recirculating exhaust gases from an internal combustion engine to an intake system of said engine, said exhaust gas recirculation valve controlling an exhaust gas recirculation amount, said control method comprising the steps of
- a) modeling said exhaust gas recirculation valve to obtain a controlled object model;
- and
- b) controlling an opening of said exhaust gas recirculation valve to a target opening based on said controlled object model.
A computer program, embodied on a computer-readable medium for causing a computer to carry out a control method for an exhaust gas recirculation valve which is provided in an exhaust gas recirculation pipe for recirculating exhaust gases from an internal combustion engine to an intake system of said engine, said exhaust gas recirculation valve controlling an exhaust gas recirculation amount, said control method comprising the steps of
- a) modeling said exhaust gas recirculation valve to obtain a controlled object model;
- and
- b) controlling an opening of said exhaust gas recirculation valve to a target opening based on said controlled object model.
A control system for an internal combustion engine, said control system comprising:
- an exhaust gas recirculation valve disposed in an exhaust gas recirculation pipe of said internal combustion engine;
- and
- a controller for controlling an opening of said exhaust gas recirculation valve to a target opening based on a controlled object model obtained by modeling said exhaust gas recirculation valve,
- wherein said exhaust gas recirculation valve controls an exhaust gas recirculation amount via said operation of said controller.
A control system for an exhaust gas recirculation valve provided in an exhaust gas recirculation pipe for recirculating exhaust gases in an internal combustion engine, said system comprising:
- modeling means for modeling said exhaust gas recirculation valve to obtain a controlled object model;
- and
- controlling means for controlling an opening of said exhaust gas recirculation valve to a target opening based on said controlled object model,
- wherein said controlling means thereby controls an exhaust gas recirculation amount.
