Abstract (en)
Learning control is carried out to learn and correct degradation in the functionality of a fuel supply pump (3) having a solenoid coil (6) for an engine. During the learning control, a temporary present learned value (ITL) to be utilized in the calculation of a target value of driving current applied to the solenoid coil is calculated. Thereafter, a final present learned value (IFL) is calculated by adding up a previous learned value (IPL) and the temporary present learned value (ITL). The final present learned value (IFL) is not immediately utilized in the calculation of the target value of driving current. Instead, the final present learned value is just stored in a memory in place of the previous learned value when the engine is stopped.
