Engine torque control with desired state estimation |
摘要 |
An engine control system and method according to the invention controls torque in an internal combustion engine. Engine parameters are measured and an engine torque is estimated. A desired air per cylinder of the engine is calculated. A desired manifold absolute pressure of a manifold of the engine is calculated based on a function of engine torque. A desired RPM of the engine is calculated based on a measured engine RPM and a reference torque of the engine. A desired area is calculated based on the desired manifold absolute pressure. The desired area is implemented into the controller to control torque output of the engine.
