Method and apparatus for determining a phase angle of a camshaft to a crankshaft of an internal combustion engine and method for monitoring the phase position of the camshaft to the crankshaft of the internal combustion engine

摘要

A method for determining a phase position of a camshaft (36) to a crankshaft (21) of an internal combustion engine, which a high-pressure pump (54) from the camshaft (36) is driven and the as a function of the switch position of a valve (56) fuel into a fuel store (55) which is operatively connected to injection valves (34), wherein the– to a predetermined crankshaft angle (crk1) a switching signal for changing the position of the valve (56) is generated and– as a function of an actual and / or expected quantity (v _ pump _ av, v _ pump _ sp) of the high-pressure pump (54) the phase position (ph _ v _ pump) is determined.
