Abstract

A process is provided for the rapid and safe activation of a fuel pump, having a definable fallback level for a delivery volume of the fuel pump. The process recognizes a possible crash situation and, defines the fallback level as a first delivery volume value which is assigned to a closing position of the fuel pump in response to the recognized possible crash situation. A control system includes a crash recognition device and an electronic fuel pump with the definable fallback level, in which case the crash recognition device is connected with respect to communication with the electronic fuel pump, and the crash recognition device is constructed for implementing the process.
