Patent ID: 7856961

Claim:
A method for automatically controlling pressure of a common rail system on an A side and a common rail system on a B side of a V-type internal combustion engine, comprising the steps of: automatically controlling rail pressure (pCR(A)) of the common rail system on the A side by an A-side closed-loop pressure control system, the common rail system on the A side having at least one injector; automatically controlling rail pressure (pCR(B)) of the common rail system on the B side by a B-side closed-loop pressure control system, the common rail system on the B side having at least one injector, the automatic control of each side being independent of the other, including setting a common set rail pressure (pSL) as a reference input for both closed-loop pressure control systems; and computing a set injection quantity (QSL) by a speed controller as a function of an actual speed (nIST) relative to a set speed (nSL), computing a common disturbance variable (VSRG) as a function of the set injection quantity (QSL), and correcting both a correcting variable (V(A)) of the A-side pressure controller and a correcting variable (V(B)) of the B-side pressure controller using the common disturbance variable (VSRG).
