Defining a region of optimization based on engine usage data

摘要

Methods and systems for engine control optimization are provided. One or more operating conditions of a vehicle engine are detected. A value for each of a plurality of engine control parameters is determined based on the detected one or more operating conditions of the vehicle engine. A range of the most commonly detected operating conditions of the vehicle engine is identified and a region of optimization is defined based on the range of the most commonly detected operating conditions of the vehicle engine. The engine control optimization routine is initiated when the one or more operating conditions of the vehicle engine are within the defined region of optimization.

1. A method of engine control optimization, the method comprising:
detecting one or more operating conditions of a vehicle engine; determining a value for each of a plurality of engine control parameters including a first engine control parameter and a second engine control parameter based on the detected one or more operating conditions of the vehicle engine; tracking a duration during which a value of the one or more operating conditions are detected during operation of the vehicle engine; identifying a range of operating condition values including the values of the one or more operating conditions that are detected for durations greater than a threshold duration; defining a region of optimization based on the identified range; and initiating an engine control optimization routine when the one or more operating conditions of the vehicle engine are within the defined region of optimization, and wherein the engine control optimization routine includes
determining a value of an engine performance variable,determining an initial value for the first engine control parameter and an initial value for the second engine control parameter based on the detected one or more operating conditions of the vehicle engine, andadjusting the initial value for the first engine control parameter and the initial value for the second engine control parameter to cause the engine performance variable to approach a target engine performance variable based on the determined value of the engine performance variable.
