Abstract
A computer-implemented method for motion estimation of a vehicle is disclosed. The method includes performing a first preliminary motion estimation based on radar sensor data, performing a second preliminary motion estimation based on inertial measurement unit sensor data, and determining a motion estimation for the vehicle as a weighted average of the first and second preliminary motion estimations. The weighted average is determined by application of a dynamically varying weighting. The weighting may vary dynamically based on one or more of: a speed of the vehicle, an ambient temperature of the vehicle, an ambient humidity of the vehicle, and an activity level of windscreen wipers of the vehicle.
