摘要： An engine control system comprises a torque control module, an air conditioning (A/C) load comparison module, and an A/C load compensation module. The torque control module controls an engine to produce a first torque request based on a first torque maintains a current speed of the engine. The A/C load comparison module compares a transient load to a difference between a torque available to the engine and the first torque request. The A/C load compensation module selectively increases the first torque request prior to a clutch engagement based on the comparison.

摘要： A method of achieving a desired engine speed of an internal combustion engine includes determining the desired engine speed, calculating a slow response torque value based on the desired engine speed and calculating a fast response torque value based on the desired engine speed. A slow response actuator command and a fast response actuator command are generated based on the slow response torque value and the fast response torque value, respectively. Operation of the engine is regulated based on the slow response actuator command and the fast response actuator command to achieve the desired engine speed.

摘要： An engine torque control module comprises a derivative module and a cylinder torque module. The derivative module determines a derivative term for a first cylinder of an internal combustion engine based on rotation of a crankshaft and determines an average derivative term for the first cylinder based upon the derivative term. The cylinder torque module determines an operating condition of the first cylinder based on the average derivative term, adjusts a torque output of the first cylinder based on the operating condition, and adjusts a torque output of a second cylinder based on the operating condition.

摘要： A throttle area compensation system for use with an electronic throttle control of a vehicle includes a compensation datastore of compensation values indexed by pre-compensated throttle area. A compensation vector learning module receives a pre-compensated throttle area and at least one sensed vehicle condition, and informs the compensation datastore based on the pre-compensated throttle area and the sensed vehicle condition. A throttle area compensation module communicates with the compensation datastore, receives the pre-compensated throttle area, and determines a compensated throttle area based on the pre-compensated throttle area and a corresponding compensation value of the compensation data store.

摘要： An electronic throttle control (ETC) system to control an idle speed of an engine includes an accessory that increases a load on the engine and a controller that generates an idle request signal based on the increased load. The controller compares the idle request signal to an idle maximum signal and sets an idle command signal equal to the idle request signal if the idle request signal is less than the idle maximum signal. The controller determines the idle command signal based on the idle request signal, a previous idle command signal and the idle maximum increase signal if the idle request signal is greater than the idle maximum signal.

摘要： Internal combustion engine control is generally in accordance with RPM and torque modes. Transition from RPM to torque control is accomplished by employing a mass airflow term accounting for any nonequivalence between RPM mode and torque mode mass airflows corresponding respectively to an RPM mode mass airflow and a closed-throttle mass airflow contribution to a total torque mode mass airflow.
