Abstract

A method for determining the absolute position of a motor vehicle in a global coordinate system, includes capturing a first position with a satellite-based navigation system and calculating a second position with at least one inertial sensor and integrating the measured values thereof. The absolute position of the motor vehicle is determined on the basis of the first position and the second position with the aid of a fusion filter. Provision is made for an error in the currently determined second position to be determined on the basis of a comparison of the first position captured last with an associated second position and to be taken into account when determining the current second position.
