Abstract
A prediction based engine control system is disclosed. The engine control system may have sensor configured to sense a current engine operation and generate a corresponding signal and a controller in communication with the sensor. The controller may be configured to receive the signal, compare the current engine operation to an allowable range of engine operation, predict a future engine operation based on the signal, and limit current engine operation based on the prediction, even when the current engine operation is within the allowable range of operation.
Claims24
A prediction based engine control system, comprising:
- a sensor configured to sense a current engine operation and generate a corresponding signal;
- and
- a controller in communication with the sensor, the controller being configured to:
- receive the signal;
- compare the current engine operation indicated by the signal to an allowable range of engine operations;
- predict a future engine performance based on the signal by determining a future value of an engine operating parameter based on the current engine operation indicated by the signal;
- and
- limit the current engine operation based on the prediction, even when the current engine operation is within the allowable range of operation.
A method for controlling an engine, comprising:
- receiving a signal indicative of a current engine operation;
- comparing the signal to an allowable range of engine operation;
- predicting a future engine performance based on the signal by determining a future value of an engine operating parameter based on the current engine operation indicated by the signal;
- limiting the current engine operation based on the prediction, even when the current engine operation is within the allowable range of engine operation.
A machine utilizing a prediction based engine control system comprising:
- an engine;
- an exhaust system associated with the engine;
- a sensor configured to sense a current operation of the engine and generate a corresponding signal;
- and
- a controller in communication with the engine and the sensor, the controller being configured to:
- receive the signal;
- compare the current engine operation indicated by the signal to an allowable range of engine operation;
- predict a future engine operation based on the comparison by determining a future value of an engine operating parameter based on the current engine operation indicated by the signal if the current engine operation is within the allowable range of engine operation;
- and
- limit the current engine operation based on the prediction, even when the current engine operation is within the allowable range of operation.
