The invention relates to a method for the open-loop control and the closed-loop control of an internal combustion engine (1) comprising an A-side and a B-side common rail system, the rail pressure (pCR(A)) of the common rail system on the A side being controlled via an A-side rail pressure control loop in a closed loop mode and the rail pressure (pCR(B)) of the common rail system on the B side being controlled via a B-side rail pressure control loop in a closed loop mode independently of each other. The invention is characterized in that once a defective A-side rail pressure sensor (8A) is detected, an A-side emergency operation mode is activated in which the A-side rail pressure (pCR(A)) is controlled in an open loop mode and the B-side rail pressure (pCR(BB)) is continued to be controlled in a closed loop mode, or once a defective B-side rail pressure sensor (8B) is detected, a B-side emergency operation mode is activated in which the B-side rail pressure (pCR(B)) is controlled in an open loop mode and the A-side rail pressure (pCR(A)) is continued to be controlled in a closed loop mode. |
