Title:
LINEARLY POLARIZED LIGHT EMISSION BY A VEHICLE HEADLIGHT, FOR USE IN A CAMERA-BASED DRIVER ASSISTANCE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/202769
Kind Code:
A3
Abstract:
The invention relates to a driver assistance system (2) for a motor vehicle (1), comprising a vehicle headlight (4) designed to illuminate the surroundings (3) of the vehicle (1) and an image capture unit (5) designed to substantially only evaluate light with a pre-definable first polarization direction in order to generate image data in accordance with the surroundings (3) of the motor vehicle (1). The vehicle headlight (4) is designed to illuminate the surroundings by providing, during normal operation in which a pre-definable light output is provided by the vehicle headlight (4), linearly polarized light (12) with a second polarization direction according to a predefinable modulation pattern (16) and/or using a pre-definable proportion of the light output. The invention also relates to a motor vehicle (1) comprising a driver assistance system (2) of this type and to a corresponding method.
