Latest Nissan Safety Technology Foils Rear-End Collisions, Boosts Parking Assist
Automakers have never shied away from implementing the latest and greatest safety technologies and Nissan’s newest contributions are the Forward Collision Avoidance Assist Concept and Moving Object Detection.
It’s a mouthful, but the Forward Collision Avoidance Assist Concept is exactly how it sounds. The technology automatically applies the brakes when radar sensors detect an imminent collision with a vehicle or object ahead, at speeds of up to 60 km/h (around 37 mph). Nissan says the speed is the highest for any collision avoidance system around and, compared to Volvo’s City Safety, this one is continuously employed at twice the Volvo system’s speed (up to 19 mph for City Safety).
In addition to the higher speed, Nissan focused on making the deceleration and stoppage as smooth as possible in an astute attempt to avoid triggering a chain reaction of rear-endings from vehicles behind. When activated, the FCAAC also tightens the driver’s seatbelt and activates visual and auditory alerts in the cabin.
The FCAAC helps vehicles in motion but Moving Object Detection assists drivers who are parking. MOD supplements Nissan’s Around View Monitor parking system and seeks out the presence of moving objects around the vehicle. Once detected, MOD alerts the driver through a screen display while a buzzer apparently emits a “PiPi” noise.
Both technologies were developed as part of Nissan’s Safety Shield concept and we should begin to see them manifest in new vehicles in the near future.

Our friends at Cars.com have put four subcompacts – the 2011 Ford Fiesta, 2010 Honda Fit, 2010 Nissan Cube and 2010 Scion xD – through their paces during a Mileage Challenge.
This group of subcompact cars demonstrates that you don’t have to sacrifice many features when downsizing or looking for a budget buy; the Mileage Challenge contenders came with power windows and locks, air conditioning, antilock brakes, side curtain airbags and more. As Cars.com’s editors discovered while driving these cars in the city and on the highway during disaster-movie-like weather, some don’t drive like a small car, either.
Which car won the Mileage Challenge and which won the hearts of our editors? Click on the links below to find out.

Stability Control Plus: New Curve Control System to Debut on 2011 Ford Explorer
Traditional stability control can help drivers avoid rollovers and stay out of slick messes. With mandatory stability control looming large for 2012, Ford is taking it to a new level by introducing âcurve controlâ for its 2011 Explorer, to help turn the SUV if the driver takes a turn too quickly.
While traditional stability control cuts power to the engine and brakes individual wheels to keep the car pointed in the right direction, curve control uses the stability control sensors to monitor vehicle inputs and dynamics 100 times per second. Curve control can intelligently apply the Explorerâs brakes, rather than cut power sharply.
Ford’s new curve control system works in conjunction with the driverâs own braking action to add more pressure to individual brakes. This works in a similar fashion to several other automakersâ electronic limited-slip differentials that brake the inside rear wheel in a turn to help the car corner better. In the case of the Explorerâs curve control, the system will apply braking pressure to all four wheels, but apply more pressure to the two inside wheels. This slows the wheels on one side of the vehicle to help the car rotate and can drop the vehicleâs speed by as much as 10 mph in one second.
Stability control systems effectively control oversteer — when the rear end loses traction and swings out, which can lead to a spin — but do little for understeer, when the driver inputs steering but the car continues straight. In practical terms, Fordâs curve control will help overzealous drivers to avoid plowing straight into oncoming traffic or a tree.
âSomething like this, weâve all done it, and you can appreciate why you would need it,â Tony Rendi, Fordâs brake control manager, told The Detroit News. Ford says that there are more than 50,000 crashes on the U.S.â curves each year.
In addition to making the new safety aid standard on the 2011 Explorer, Ford plans to add it to 90 percent of its North American SUVs, trucks, vans, and crossovers by 2015. The system debuts on the new Explorer, due out later this year.
