Mazda Motor Corporation will showcase its Adaptive LED Headlights (ALH) next-generation headlamp technology at CEATEC JAPAN 2014, a comprehensive exhibition of cutting-edge IT and electronics. Mazda will also exhibit a Mazda3 featuring a unique implementation of automated driving technology.
ALH is a next-generation headlamp system implementing LED array glare-free high beam technology. Mazda says it is the first Japanese automaker to reveal such a system to the public.
With an LED array, the LED light source for the high beams is divided into four blocks which can be switched on and off independently. The system uses a camera to detect the headlamps of oncoming vehicles or the taillights of cars ahead, and turns off only the light-source block which is illuminating in the specific direction of the other vehicles. This makes it possible to drive with the high beams on at all times, significantly improving visibility when driving at night, without dazzling drivers of other vehicles.
ALH also features wide-distribution low beams. By adding an LED light source to the side of the headlamps, wide-distribution low beams expand the area of illumination on either side of the vehicle, illuminating areas where traditional headlamps cannot. This makes it easier to see pedestrians and other obstacles at intersections at night. In addition, Highway Mode utilizes the motor of the headlamps' auto-leveling mechanism to automatically raise the axis of lighting when travelling at highway speeds, making it easier to see road signs and obstacles as early as possible.
Mazda3 with automated driving technology. Mazda is developing an automated driving system to watch over people constantly—especially the condition of the driver—with the aim of helping to avoid driving errors and situations where an accident becomes unavoidable. This model is equipped with high-precision GPS, technologies which sense the state of the vehicle, and motion control technologies that focus on human senses.
Mazda will also exhibit its new-generation HMI which puts top priority on safe driving and minimizes the factors that lead to driver distraction. The HMI includes a 7-inch center display that ensures maximum legibility, a commander control knob designed to be operated by touch alone, and an Active Driving Display which projects a virtual image of essential information, such as the vehicle speed, above the meter hood.
CEATEC JAPAN 2014 runs from Tuesday, 7 October through Saturday, 11 October 11 at the Makuhari Messe convention complex in Tokyo.
