3. All-Around Collision Free Prototype (technology that helps the driver recover from a dangerous to safe condition)
Nissan believes the person does the driving. Based on this perspective, the company has been developing the technology to maneuver the vehicle in a manner that drivers can feel intuitively, such as with a display and sound.
In 2007, the Distance Control Assist (Intelligent Pedal), which delivers information on the vehicle in front of a driver, was introduced for the first time in the Fuga (Infiniti M) in Japan. In North America, the Lane Departure Prevention, which conveys danger at the side of a driver was introduced with the new Infiniti EX in 2007.
At the Advance Technology Briefing, we disclosed the world's first technologies, the "Side Collision Prevention" and the "Back-up Collision Prevention". The "Side Collision Prevention" is a driving support system for changing lanes and the "Back-up Collision Prevention" is the system for backing up. Combined with the existing technologies already available in our vehicles, we disclosed the All-Around Collision Free Prototype.
- Outline of the All-Around Collision Free Prototype -
We conducted test drives for the participants to experience the Side Collision Prevention system. As shown in the picture, the test drive vehicle changes lanes while another vehicle runs parallel to it slightly behind.
As another vehicle approaches behind in the next lane, a light is activated. When it backs away, the light turns off. If a lane change occurs while the light is on, a warning sound will commence and a rotating movement, which is generated by controlling each brake individually (not by steering), warns the driver in an intuitive manner that the vehicle is approaching.
Some of the participants wondered what would happen if the driver continued to change lanes, even after noticing another vehicle was approaching. As this system is not an automated driving system but a driving support system, if the driver continues to change lanes after the rotating movement is generated, the system understands and the driver can continue changing lanes.

4. Intelligent Seatbelt, Items to Promote Rear Seatbelt Fastening (technology that helps minimize damage when a collision is unavoidable)
- Experiencing Intelligent Seatbelt -
When wearing the Intelligent Seatbelt, the motor extends the belt and the anchor (buckle attached to the belt) comes closer to the hands with the belt guide supporting the seatbelt installation. In abrupt stops and skid situations, the improved restraint function pulls the belt in to secure passengers.
Items to promote rear seatbelt fastening includes the Low-friction Seatbelt and Self-standing Buckles. Incorporating a new weaving method, the low-friction Seatbelt reduces friction by 10% when the seatbelt is pulled out. Tightness is also reduced by 20%, which increases comfort. The Self-standing Buckles have belt slots that are easily identified and can be fastened with one hand. With this technology, Nissan hopes that backseat passengers always wear their seatbelts.
5. Summary of safety technologies
Nissan has been working on safety technologies from various perspectives, including it's efforts in promoting rear seatbelt fastening and the Active Headrest. We have also enhanced these safety technologies with efficiency and resourcefulness.
Our efforts are not only in the mature markets such as Japan, the US and Europe, but also in the emerging markets. While Nissan offers innovative technologies for various markets, it is working to provide improved safety for all our customers.
