1. For an electromagnetically operable valve element which is moved against an elastic restoring force by means of a capturing current pulse, which energizes an assigned solenoid, into an end position defined by a stop element, reaching an impact velocity, a method for controlling said impact velocity, comprising:

  • determining a switch-on point in time for the capturing current pulse for each valve operation cycle, which determined switch on point in time is equal to a switch-on point in time for a preceding valve operation cycle plus a control increment, defined as a minimum target function of a gradient of impact velocity with respect to switch-on point in time based on preceding operation cycles; and

    adjusting a switch-on point in time of the capturing current pulse for each valve operation to equal said determined switch on point in time.
