Abstract
Description
technical field
[0001] The invention relates to a method for plausibility verification of at least one light detector of a driving light assistant of a motor vehicle. Furthermore, the invention relates to a computer program and a computer program product having program code segments for carrying out such a method. Background technique
[0002] Driving light assistants or driving light assistants for motor vehicles are known in practice, which measure the light properties of the surrounding environment by means of light detectors or light sensors (ALS—Ambient Light Sensor: Ambient Light Sensor) and correspondingly Automatically turn on the low beam headlights of the motor vehicle at dusk / darkness.
[0003] Similar vehicle sensor systems, in particular rain light sensors or rain sensor arrangements, often have a self-diagnosis function which is carried out repeatedly at cyclical time intervals during operation. The process is used to detect possible faults early and to infor...
