According to foreign media reports, although the high beam can penetrate thick fog, it will cause dazzle to the oncoming drivers, because most commercial high beam systems will not automatically adjust to compensate for the brightness of the sun, so it is easy to cause dazzle. (image source: INVISTA) the drive labs Department of INVISTA has developed an artificial intelligence (AI) solution for this problem, autohighbeamnet. Based on the camera system, this scheme is a component of the autodrivingbeam module of the NVIDIA drive software, which can automatically control the output of the high beam of the car by using the road condition signal. Autohighbeamnet uses the image data of the front camera, then processes and outputs it to autodriving beam, and the automobile manufacturer can customize its format according to the speed, environmental conditions, etc. NVIDIA said autohighbeamnet would not generate control signals based on the lux intensity of other light sources, but would respond to the perceived active vehicles in the camera frame. (if there are parked vehicles on the side of the road and the lights are off, they will be ignored.). The control signal can be in one of two modes: automatic high beam (AHB) mode (control on / off) and adaptive high beam (ADB) mode (control of a single high beam LED array to create a "no glare" area). In AHB mode, the vehicle's high beam will automatically turn on in case of poor lighting conditions at night. If an active vehicle is detected, the high beam will automatically turn off and switch to the low beam. In ADB mode, if another vehicle is detected, the high beam can dim the single LED in the high beam LED array headlamp to prevent dazzling the active vehicle. NVIDIA said there was an application interface (API) to support AHB mode in the 10.0 version of the NVIDIA drive, while automakers needed to customize policies to control high beam lights.
