Weesp (The Netherlands), August 27, 2007 – Adaptive front lighting systems (AFS) redirect low-beam headlamp units individually in a horizontal direction in accordance with steering angle and vehicle speed. As a result, these systems can improve visibility during nighttime cornering, ensuring safer driving.
At 2007 IAA Frankfurt Motor Show, DENSO demonstrated its new AFS, currently under development, which further improves visibility in a curve. The new AFS predicts curves in the road ahead using road information from the car navigation system, and redirects headlamps to illuminate the road, before the vehicle enters the curve. This enhances visibility for the driver sooner. DENSO is working to improve the accuracy of position information from the navigation system before commercializing the new technology.
The world’s first AFS was developed by DENSO together with Toyota Motor Corporation and Koito Manufacturing Co., Ltd., in 2003. For this system, DENSO developed an AFS electronic control unit (ECU) and swivel ECU. In January 2006, DENSO launched its new AFS ECU, which is approximately 70 percent smaller in volume compared to the conventional AFS ECU. In addition to its smaller size, the new ECU can provide more detailed light distribution control in accordance with road conditions and vehicle speed, resulting in improved visibility.
DENSO is developing and supplying automobile safety systems and components in two distinct areas: active safety for collision warning and avoidance, and passive safety for damage minimization in the event of collision. In the pursuit of a safer automotive society, DENSO continues to improve safety systems.
