Abstract:
1. A method for simultaneously adjusting camshafts of different cylinder banks of an internal combustion engine to a predetermined nominal angle relative to a crankshaft, where the camshafts actuate associated intake or exhaust valves of the corresponding cylinder banks of the internal combustion engine, the method comprising the steps of: detecting a difference in adjusting speeds of associated actual angles of the camshafts; and time the nominal angle of at least one of the camshafts with a higher adjusting speed being changed over time until the actual angles of the camshafts have reached the predetermined nominal angle, the nominal angle for the camshaft with the higher adjusting speed being changed over time so that a divergence between the actual angles of the camshaft with the higher adjusting speed and the actual angles of the camshaft with the lowest adjusting speed is first stopped and a then corresponding difference between these actual angles is reduced.
