Automobile hydraulic unit (for HP) the electromagnetic control valve (CV) the digital closed looping circuit which controls electric current

摘要

Has a (CLS) digital closed-loop circuit for controlling the current solenoid control valve automobile hydraulic unit of (HP) for (CV) of the robust to ripple of on-board power supply, as the weight of the closed-loop operation of the circuit (CLS) automotive control apparatus adapted to improve the dynamic characteristics with respect to (ST) jump target current of (SS) in (CO), the feedback path of the digital closed-loop circuit (CLS) to (FB) at least adaptive correction filter of one 1 (KFI) provided that, (FT1, FT2) is dynamically adjustable based on level change of the target current (SS) to (S1) filter time of the adaptive correction filter.
