Patent ID: 7475534

Claim:
Method for controlling fuel injection in an internal combustion engine ( 10 ) having at least one electric machine ( 26 ), wherein a direct injection system ( 18 ) for direct injection of fuel into at least one combustion chamber ( 54 ) of the internal combustion engine ( 10 ) is associated with the internal combustion engine ( 10 ), with the direct injection system ( 18 ) including a mechanically driven fuel pump ( 22 ) for generating a fuel pressure in an accumulator volume ( 20 ) upstream of the at least one combustion chamber ( 54 ), the method comprising the steps of: during a startup phase of the internal combustion engine ( 10 ), at least after fuel injection has begun, monitoring a run-up course of the internal combustion engine ( 10 ) by measuring engine rotation speed, and if a deviation of the run-up course between a desired course and the measured engine rotation speed is detected, at least substantially compensating for the deviation by performing a motor intervention with of the at least one electric machine ( 26 ) wherein the at least one electric machine ( 26 ) performs the motor intervention by supplying torque to a crankshaft of the internal combustion engine ( 10 ) to substantially compensate the detected deviation.
