All-new Mazda Atenza

All-new Mazda Atenza / CX-5: Adaptive LED Headlights demonstrates evolution in safety performance

One of the recent technological topics in the automotive industry is automated driving. Many automakers are competing fiercely with their respective automated driving technologies to countervail emerging players like Google. Amidst all these technologies, Mazda’s advanced safety technology, i-ACTIVSENSE, has a unique stance.

I learned from the presentation of Hiroshi Omura from Mazda’s Vehicle System Development Department that the all-new CX-5 and the all-new Atenza are both equipped with these safety technologies.

Omura said, “Mazda’s safety philosophy put emphasis on humans. I think that providing information to the driver is important. Specifically speaking, I’m referring to a technology that recognizes potential hazards. This is because we believe that drivers are more intelligent than machines.”

Mazda’s i-ACTIVSENSE performs driving support and cruise control using the milliwave radar on the front grille, the camera on the rear-view mirror, and infrared lasers in its rearview mirror. The rear sonar system uses two milliwave radars.

The updates to i-ACTIVSENSE include improvements to the Smart Brake Support (SBS/Automatic Brake). A reverse gear functionality has been added to the current SBS to prevent collision by unintentional acceleration. A first for Mazda, the all-new Atenza and CX-5 are equipped with Lane-keep Assist System (LAS) and Driver Attention Alerts (DAA). They are also equipped with Adaptive LED Headlights (ALH), a first for Japanese automakers.

Both cars serve as samples, for both domestic and imported cars, that show the qualities of a car made by Mazda. The ALH especially demonstrates their unique commitment.

Omura added, “The ALH does not use mechanical shutters to cover the headlights. Instead, it independently switches on or off the LED lights to avoid dazzling the preceding vehicle. Furthermore, the widened low beam will only work when driving at slow speeds. We want drivers driving at high speeds to be able to concentrate on what’s in front of them, so we deliberately removed the low beam coverage at high speeds.”

The demonstration using a darkroom perfectly showcased the LED brightness that changes depending on the speed and steering angle, the accurate changes to the illumination according to angle changes, and the turning off of the high-beam block shining in the direction of an oncoming or preceding vehicle to avoid impairing other motorists’ vision.

The ALH is a crystal clear example of Mazda’s stance in technology. ALH is not a technology developed for the sake of innovation; instead, it has been developed for people to use.
