Abstract
A control system and method of regulating operation of an engine includes a minimum torque module that determines a torque request based upon at least two of measured revolutions per minute (RPM) of an engine, a barometric pressure, and a coolant temperature of the engine. A first engine air module can determine a first desired engine air value based upon predetermined actuator values and a torque value based upon the torque request. The predetermined actuator values can include a predetermined RPM of the engine. A throttle area module can determine a desired throttle area based upon the first desired engine air value and the predetermined RPM.
Claims20
An engine control system comprising:
- a minimum torque module that determines a torque request based upon at least two of measured revolutions per minute (RPM) of an engine, a barometric pressure, and a coolant temperature of the engine;
- a hybrid optimization module that generates a torque value based upon said torque request and that generates an electric motor torque value based upon said torque request;
- a first engine air module that determines a first desired engine air value based upon predetermined actuator values, said torque value and said torque request, wherein said predetermined actuator values include a predetermined RPM of the engine;
- and
- a throttle area module that determines a desired throttle area based upon said first desired engine air value and said predetermined RPM.
