Patent ID: 7640095

Claim:
System for controlling an internal combustion engine comprising: a first cylinder line and a second cylinder line, each having a first camshaft for the gas intake valves and a second camshaft for the gas discharge valves of cylinders assigned to the respective cylinder line; an adjustment device to set a valve overlap between the gas intake valves and the gas discharge valves, wherein the adjustment devices are assigned to the first cylinder line and the second cylinder line; an actor assigned to at least one of the cylinder lines; a lambda controller assigned to each cylinder line, wherein a controller variable acts on the actuator; and a detecting and control device effective to: detect values of a variable, which are based upon a torque generated by the first cylinder line and the the second cylinder line, as non-valve-overlap values of the first cylinder line and the second cylinder line in a first operation situation of the internal combustion engine, when the valve overlap is sufficient smaller so as to have no influence on the torque, detect values of a variable, which are based upon the torque generated by the first cylinder line and the the second cylinder line, as valve-overlap values of the first cylinder line and the second cylinder line in a second operation situation of the internal combustion engine, when the valve overlap is sufficient greater so as to have an influence on the torque, determine a correction value for the adjustment device assigned to the first cylinder line based upon the valve-overlap values and non-valve-overlap values of the first cylinder line; determine a further correction value for the adjustment device assigned to the second cylinder line based upon the valve-overlap values and non-valve-overlap values of the second cylinder line; activate the adjustment device of the first cylinder line based upon the assigned correction values; and activate the adjustment device of the second cylinder line based upon the assigned correction values.
