Approach for Traffic Safety

From the viewpoint of securing the field of vision of drivers, we target zero traffic accident and contribute to the realization of a safe and secure mobile society.

Stanley products and functions contributing to traffic safety

AFS(Adaptive Front-lighting System)/ADB(Adaptive Driving Beam)

AFS is a system to swivel the light to match the steering angle in order to improve the view in the front direction when a driver is driving on a bend. Through the development of ADB, we target further enhancing the view during nighttime.
ADB is an image-recognition camera system, which detects preceding or approaching vehicles. The light of the high beam is partially blocked out to help prevent dazzling the driver of oncoming cars.
Thanks to this function, it enables more information necessary for driving such as information of range, pedestrians on the shoulder of a road and signposts and it is possible to drive with a high beam-like view when another car is in front.

LED headlamps

LED headlamps realize brightness equivalent to HID (high intensity discharge) headlamps, have irradiation distribution design of light that irradiates the necessary range at optimal brightness and are eco-friendly with power consumption of about 2/3 that of HID lamps.
In addition to environmental friendliness, LED headlamps can offer lamplight with high visibility when compared with conventional light sources, contributing to enhanced safety.

Laser headlamps

Laser headlamps use the next-generation laser-excited light source.*
This light source has a smaller beam size than an LED. The headlamps can be made smaller while producing much brighter light.
The high brightness of the light source improves long-range visibility for greater safety.
*A light source that uses laser beams to create white light.


Laser headlamps used in SIM-CEL

SIM-CEL, the third electric vehicle prototype by SIM-Drive Corporation, became the world’s first road licensed vehicle to use laser headlamps, which were provided by Stanley Electric.

Auto leveling

Auto leveling is an adjustment system in which the irradiation direction of headlamps is maintained in a constant direction even if the posture angle is changed depending on the riding condition. Thanks to this function, glare against oncoming cars can be prevented, while optimal irradiation distribution is provided for drivers.

Night view system/side view system
The night view system visualizes traffic conditions out of the irradiation range of the lamps by taking advantage of near infrared beams. The side view system offers the information of vision at the sides of automobiles that are in dead angles from the driver, supporting safe driving. In each system, Stanley's infrared beam units and LEDs contribute to expanding the vision of drivers.

DRL(Daytime Running Lamps)

Daytime running lamps are always lit, enhancing visibility from surrounding cars and pedestrians. With better recognition of the car's presence, it contributes to safety.

Stanley's initiatives for human factors, contributing to traffic safety

Human factor research at Stanley, focusing mainly on aspects relating to vision, evaluates how people perceive light from vehicle lamps such as headlights and brake lights, and also interior and exterior lighting.

Taking part in studies at the University of Michigan Transportation Research Institute, we obtained expertise on analyzing nighttime accident data and performing experiments for objectively evaluating safety, employing this know-how in our assessment of developed products.

As one example, we conducted experiments to determine the optimal LED light spectrum for headlamps, based on ease of night driving and visibility of center lines and other road markings. We then applied the findings to the development of LED headlamp products. We further took part in ADB (Adaptive Driving Beam) development, defining requirements based on the characteristics of human vision and from a human factor standpoint, and conducting evaluation and testing.

Our coming research efforts are not limited to lighting and vision but extend to human senses regarding operability and design, such as the usability of operating panels for car air conditioners. The aim is to develop products that are easier to use based on human characteristics.

We are committed to carrying on with efforts, from a human factor standpoint, to develop excellent products that are even safer and more convenient, contributing to the safety and peace of mind of the public.
