controlling fuel injectors using correlated gain curve data

Methods and systems are provided for controlling fuel injectors included in a fuel injection system of an internal combustion engine of a vehicle. The fuel injection system includes a fuel rail. The methods and systems measure data for the fuel injector relating fuel injection flow rate and fuel injector energization time at a first rail pressure. The methods and systems transform the measured data using a correlation function t to correlated data relating fuel injection flow rate and injector energization time at a second rail pressure different from the first rail pressure. The methods and systems control the fuel injector using the correlated data relating fuel injection flow rate and injector energization time. 提供了用于控制包括在车辆内燃机的燃料喷射系统中的燃料喷射器的方法和系统。燃料喷射系统包括燃料轨。所述方法和系统测量燃料喷射器的与第轨压下的燃料喷射流量和燃料喷射器激发时间有关的数据。所述方法和系统利用相关函数t将测量数据变换成与不同于第轨压的第二轨压下的燃料喷射流量和喷射器激发时间有关的相关数据。所述方法和系统利用与燃料喷射流量和喷射器激发时间有关的相关数据来控制燃料喷射器。
