METHOD AND SYSTEM FOR EVALUATING BRIGHTNESS VALUES IN SENSOR IMAGES OF IMAGE-EVALUATING ADAPTIVE CRUISE CONTROL SYSTEMS, ESPECIALLY WITH RESPECT TO DAY/NIGHT DISTINCTION

摘要

The invention relates to a method and a system for evaluating brightness values in sensor images of an image-evaluating adaptive cruise control system on a support. According to the invention, at least the amplification and/or the exposure time of the at least one image sensor detecting the surroundings is monitored to distinguish the light conditions in the area of the image-evaluating adaptive cruise control system with respect to day or night. A course of amplification and/or exposure time over time with relatively high amplification or relatively long exposure times characterizes night light conditions and a course of amplification and/or exposure time with relatively low amplification and/or relatively low exposure times characterizes day light conditions. The adaptive cruise control system according to the invention also allows monitoring of the detected surroundings for bright objects, the headlights of a second support being used as an additional piece of information.
