Nissan’s New Techs
Nissan last week unveiled a host of technologies spanning safety, fuel cells, transmissions and a new hybrid system for front-wheel drive vehicles. Below are videos of several of the new techs.
First, let’s look at some of the new safety features.
①Acceleration Suppression for Pedal Misapplication
To help reduce collisions with obstacles such as a wall due to the driver’s accidental pushing of the accelerator or by pressing too hard in car parks or other confined areas, Nissan has developed a function to recognize whether the vehicle is on a road or in a car park using image signal data acquired by the Around View Monitor’s four unit cameras.
②Multi-Sensing System with Rear Camera
Using the Around View Monitor image-processing technology, Nissan developed the Multi-Sensing System with Rear Camera. This detects people, other vehicles and road conditions to the rear or sides of the vehicle, alerting drivers to possible risks of collision. This system has three functions—lane departure and blind spot warnings plus detecting moving objects to the rear of the car—and will be installed in new models from 2012.
③Predictive Forward Collision Warning System
To help prevent accidents when a vehicle in front slows suddenly, a front-mounted sensor analyzes relative speeds and the distance to the car ahead. When it’s necessary to brake, the system warns the driver with a buzzer, a signal on the car’s display and tightens the seatbelt.
④Multi-sensing system with front camera
Taking one’s eyes off the road even momentarily can cause serious accidents. Nissan has worked to develop a technology that supports safe driving by monitoring the road ahead—for instance, pedestrians crossing the road—and warning of potential accidents.
Next, let me introduce our latest environmental technologies:
⑤New Generation XTRONIC CVT
The new generation XTRONIC continuously variable transmission (CVT) for 2.0 to 3.5 liter engine vehicles raises fuel economy by up to 10 percent,*1 compared with the previous system. The new transmission features world-leading ratio coverage of 7.0*2, and reduces friction by up to 40 percent. When combined with Adaptive Shift Control, which tweaks shifting patterns to match each driver’s style and road conditions, the new XTRONIC CVT delivers more responsive and powerful acceleration. It also helps prevent the engine from revving too fast at high speeds, reducing noise. This generation of the XTRONIC CVT will be first introduced in North America from 2012.

*2 Specific to 2.0 to 2.5-liter engine vehicles
⑥New Hybrid System for Front-Wheel Drive Vehicles
Nissan’s new hybrid system takes an innovative approach to the twin challenges of affordability and efficient packaging. It mates a single electric motor and two clutches with the new generation XTRONIC continuously variable transmission and combines them with a compact lithium-ion battery pack and a 2.5-liter supercharged engine. The result is a compact, versatile powertrain that doesn’t require a specially designed body. It delivers power equivalent to a 3.5-liter engine, but with much better fuel economy in city and highway driving conditions. Nissan plans to release a new hybrid vehicle in North America in 2013, and later in other markets.
⑦Wireless Charging System
Nissan has developed its Wireless Charging System for electric vehicles that allows recharging to take place simply by parking the vehicle over the charger. Just like the charging system on a cordless toothbrush, it works by induction and requires no cables.
⑧Next Generation Fuel Cell Stack
With a new fuel cell system, Nissan has made great strides in two critical areas: power density and cost. A new 2011-model fuel-cell stack delivers power density at 2.5 kilowatts per liter, or 2.5 times better than the 2005 mode, helping making the pack significantly smaller. Nissan has also cut the cost by 85 percent by reducing the amount of platinum used in production by 75 percent.
