Abstract
In order to operate an injection valve, a freewheeling operating state is controlled as the nozzle needle moves to its closing position, and a current through the coil is detected as a freewheeling current during freewheeling. As the nozzle needle moves to its closing position, a braking current pulse (I_BR) is generated on the basis of a time derivative (DI_DT_FW) of the freewheeling current and is impressed on the coil.
