Method for noise reduction during tracking of measured values of surroundings sensor in driver assistance system of car for determining filtered trajectory of values, involves adaptively implementing noise reduction of measured values

摘要

The method involves adaptively implementing noise reduction (R) of measured values of a surroundings sensor e.g. ultrasonic sensor, based on a distance (d) of a tracking object from a motor vehicle (1), where noise reduction for measured values close to the vehicle is smaller than noise reduction for measured values remote from the vehicle. The noise reduction is caused by temporal averaging of the measured values. A position and/or speed and/or acceleration and/or shape parameter and/or orientation and/or yaw rate of the object in surroundings of the vehicle are determined by the sensor.
