Hella Rain Light Sensors Begin Series Production In China

FORVIA HELLA Starts Production Of New Rain Light Sensor Technology

On July 28, Hella GmbH & Co KGaA (FORVIA HELLA) announced the start of series production for Hella Rain Light Sensors developed and manufactured locally in China. The new-generation sensor is supplied to a well-known local new energy vehicle manufacturer and combines multiple sensing functions within one compact module. The integrated system monitors rainfall, ambient light, sunlight intensity, and windshield temperature and humidity, enabling improved vehicle automation, enhanced visibility management, and better passenger comfort through intelligent environmental perception.

Integrated Multi-Sensing Capability For Intelligent Vehicle Functions

The new-generation sensor from FORVIA HELLA adopts an absolute measurement principle to detect extremely fine rainfall levels and accurately capture rain distribution patterns. This allows the vehicle system to automatically adjust wiper speed according to real-time weather conditions. By combining multiple sensing technologies into a single compact unit, the solution reduces system complexity while supporting advanced vehicle functions. The technology is designed to improve driving convenience and provide more precise environmental data for modern passenger vehicles, particularly in the growing new energy vehicle segment.

Advanced Light And Climate Monitoring Functions

The ambient light detection function uses infrared light from the vehicle front and visible light from the roof area to support intelligent low-beam switching. This approach helps optimize lighting decisions while reducing potential glare during nighttime driving conditions. The sensor also measures sunlight intensity from left and right seating positions, allowing vehicle systems to make more accurate air-conditioning adjustments. Continuous monitoring of windshield temperature and humidity further supports anti-fogging functions by identifying conditions that may reduce visibility and enabling timely corrective actions.

Local Production Supports China New Energy Vehicle Growth

The localized development and production of this sensor technology reflects the increasing demand for advanced automotive components in China's rapidly expanding new energy vehicle market. The integration of rainfall, lighting, climate, and visibility-related sensing into a single module demonstrates the industry shift toward smarter and more efficient vehicle architectures. Through this solution, FORVIA HELLA strengthens its position in intelligent vehicle systems by providing compact sensing technologies that support enhanced safety, comfort, and automated driving experiences.
