Abstract:
A method for determining an instantaneous fluid level of a motor-vehicle tank, comprising the steps of:A) designating a beginning fluid-level of the motor-vehicle tank as an input value during a starting of a motor-vehicle engine; B) ascertaining a first fluid-level value from a fluid level measured by a fluid-level measuring device, and ascertaining a second fluid-level value and a window around the second fluid-level value from a fuel consumption value of the motor-vehicle engine and from the input value; C) determining whether the first fluid-level value is inside the window around the second fluid-level value; D) determining whether the first fluid-level value or the second fluid-level value is a new input value based on whether or not the first fluid-level value is inside the window around the second fluid-level value; E) displaying the new input value as the fluid level; and F) one of terminating the method if the motor-vehicle engine is shut off and repeating the steps A) to E) if the motor-vehicle engine is running.
