摘要:
A method of controlling a fuel injector valve solenoid includes generating a set-point signal which models a desired current profile flowing through the valve solenoid, providing a current controller which is adapted to regulate the current flowing through the valve solenoid, and regulating the current flowing through the valve solenoid such that the current flowing through the valve solenoid closely matches the set point signal. Regulating the current includes measuring the current flowing through the valve solenoid, comparing the current flowing through the valve solenoid to the current profile of the set-point signal, and adjusting the current flowing through the valve solenoid to more closely match the current profile of the set-point signal.
