Compare Backup Sensors & Cameras to ParkFX

Get the Latest Information on the Most Reliable Backup Warning Technologies

Not all reversing aids are equal. The sensing technology and the indicating method are critical to your driving safety.

How a park assist system alerts you

One option is video, which at first seems like a great choice. But one major flaw with having a video camera affixed to the back of your car with a monitor on your dashboard is that it also forces you to look forward while backing up. That can disturb your perception, your reaction time, and feel very unnatural. They are also extremely expensive, and you'll pay thousands of dollars to have a video system attached to your car, whether from the dealer or an aftermarket supplier.

Compare that to other bargain basement devices which actually have LED displays (little red lights) on your dashboard. These are cumbersome -- almost useless -- for much the same reason as video: when you drive in reverse, you naturally look behind you, and you'll never see the little red lights. They are also hard to read in bright sunlight.

Some other bargain technologies use a tone which beeps more rapidly as you get closer to an obstacle. You can at least hear the relative distance just by listening to the beeps, but you have to practice a bit to really understand how far you are from danger.

That's why an audible voice sensor is best. It tells you in a spoken voice exactly how far away you are. Not only do you not have to awkwardly look forward at your dashboard, you'll know without guessing how much further you can safely back up.

How a reversing aid detects objects

If you've never seen or used a reversing aid, you might be surprised at how technically advanced they actually can be.

Reversing aids use a variety of technologies to sense an object behind the car. Some units use Doppler radar, and others use infrared sensors, but by far the most accurate method of detection is the one the U.S. Navy uses on its submarines: sonar.

Sonar can operate in any weather, including direct sunlight or rain. And it doesn't require that the car be moving in order to sense an obstruction.

Top 5 Auto Safety Technologies

Which of the often-expensive new technology might really save your life? Cars and trucks have become a lot safer in the past decade, but some 43,000 people still die every year on U.S. highways. To be sure you and your family do not wind up among these statistics, you want the latest and best auto safety equipment available when you buy a new car. But unless you can afford a luxury car--where most safety gear will be standard--you will have to make choices about how much to spend on optional auto safety equipment.

Some state-of-the-art auto safety devices--such as blind spot detection systems --aim to help you survive once an accident happens. Others--even better--help to control skids and other dangerous situations, aiming to avoid accidents entirely. To stay safe, you ideally need both preventive and protective equipment. New auto safety gear may be especially important if you are thinking about buying a sport utility vehicle (SUV).

Automakers are Designing New Car Gadgets Focused on Driver Safety and Awareness

Safer Lane Changes is Just One of the Latest Trends to Include Advanced Gadgets in New SUV Models

Every new car season brings with it a dazzling assortment of high-tech gadgets and an equally formidable barrage of hype aimed at romancing you into this year's model.

What's hot and what's hype? We posed that question to Paul Duchene, a national automotive writer based in Portland, Ore.

"There are a lot of gizmos this year and some of them are good, too," he says. "One of the reasons is there are a lot of new models and a whole bunch of updates this year, including the Nissan 350Z, Mazda's RX-8 and BMW's Z4 and 745i, the car some critics have informally dubbed 'the quarter to eight.'"

Let's put the pedal to the metal and cruise some of this year's hottest new gadgets:

Intelligent cruise control: This lends new dimension to the term "keeping up with the Joneses." Previously, cruise control was a simple proposition: You set your speed and your car maintained it until you tapped the brake or manually turned it off. Infiniti's new wrinkle uses a laser beam to measure the distance between you and the vehicle ahead and maintains a preset distance until you disengage it. The upside is you can't tailgate. The downside depends on the driving skills of the guy in front of you.

Directional stability: This is a little like having your mother-in-law in the back seat, only quieter. "You go into a corner too hard and the car basically figures out that it's about to change direction from where you want it to go and will selectively apply, say, a rear brake on one side just to keep it going in the line that it senses it's pointed," says Duchene. And he tested it. Hard. "It really works, way past the point that it makes sense."

Mouse control: It had to happen and finally does with BMW's 7 series. That dial-shaped gizmo where a stick shift would normally reside is called iDrive and it controls the heat, air, audio level and other cabin-related functions. This gives you a sleek, button-free dashboard. Beginners, however, need to look at the in-dash display to use it.

Voice-recognition system: Sure, we all talk, even scream, at our cars on occasion. Now Infiniti presents one that finally listens. The Q45 voice recognition system allows you to change CDs, adjust the temperature, access your GPS navigation system or make a hands-free cell phone call, all through voice command. The system understands 50,000 words in 150 dialects and even learns the sound of your voice. Hal, is that you?

Run-flat tires: No matter how high-tech your ride, there are four things all cars have in common, and they still go flat from time to time. Run-flat tires don't prevent flats, but they will get you to a repair shop. "When you run over a nail and the tire goes flat, if you keep it under 30 miles per hour, it will get you someplace where you can change it," Duchene explains. "Part of the reason they can do it is that performance tires are much lower profile and deform much less, so you can make stiffer sidewalls."

Mobile entertainment: New minivans approximate all the comforts of home: Pop-down DVD screens, earphone ports, even a remote control to fight over. That takes care of the kids; now what about Mom and Dad? How about coast-to-coast, commercial-free satellite radio? For the cost of a radio receiver ($300 and up) and service (less than $15 a month), you can receive 70 channels of commercial-free music and 40 channels of news, talk, sports and entertainment programming from such providers as XM and Sirius. It sure beats choruses of, "Are we there yet?"

Limp-home mode: How smart is the Cadillac Northstar engine? If you blow a radiator hose, the Northstar automatically reverts to limp-home mode, shutting the gas supply off in several cylinders and turning the engine into a quasi-air cool system. You won't set any land speed records, but your engine will survive the damage you unwittingly might have done to it.

DVD navigation: Because of the limited data storage capacity of earlier onboard GPS satellite-navigation systems, you had to reinstall a different CD of map displays if you wanted to travel to other parts of the country. With the new DVD-based systems, all of North America is now your oyster. Does it play movies, too? Duchene chuckles: "The Lexus system has the ability to play movie DVDs on its screen, but it won't play if you're in gear, so you can't be watching a movie while you're driving down the road." We really didn't think so, but had to ask.

Automatic braking: Remember your mother-in-law in the back seat? Here's a feature that cleverly simulates the effect of her panicked stranglehold on you in a traffic crisis. "There are brake systems now that have a brains-override thing where they figure you're not braking hard enough for what's going on and will actually add power to the brakes," Duchene says. Easier on the esophagus, too.

Head restraint, side curtains and pre-tensioners: Luxury cars feature all the safety money can buy. In addition to standard forward and side airbags, many models now come with inflatable head-restraint bands along the top of the windshield and inflatable side window curtains. The Lexus system automatically cinches up your seat belt with pre-tensioners just milliseconds before impact. Cadillac's Escalade SUV uses sensors to analyze the size and weight of front-seat passengers and automatically deactivates the front air bag if it detects a child or rear-facing child seat riding shotgun. "Though not yet on the market, the car companies are developing a 'catcher's mitt' seat that, if things go wrong, just kind of grabs you and holds you in place," says Duchene.

Back-up assistance: If parallel parking is not your strong suit, you'll be pleased to hear about a couple systems designed to give you a better look at your rear end. GM's Ultrasonic Rear Parking Assistant uses four sensors to triangulate the position of objects behind you and guides you with both an audible chime and LED lights at the back window. Infiniti's RearView Monitor goes one step further and actually displays on the dashboard monitor a full-color video from a rear-mounted mini-cam. Now all you've got to do is find a parking space.

Automatic accident reporting: In the event of an accident, your car can now phone for help, even if you can't. "Some of this stuff now, if you have a crash, the car calls home and 911 and says, 'I've been hurt,'" Duchene says. "But that has its drawbacks. As one of my friends pointed out, sometimes when you make a mistake, you could use about 20 minutes to get away."

Device Reads Email Messages to Drivers

Tech Digest reports on a new gadget and speech recognition system called iLane that provides drivers with a hands-free way of listening to email messages. iLane can also handle phone calls, calendar requests and SMS messages. The device plugs into the cigarette lighter.

iLane is a small device that interacts directly with existing Bluetooth-enabled handheld devices, allowing drivers to fully access their email in transit. iLane notifies the driver of incoming emails and other important information by reading a brief summary in a "natural sounding voice". The driver can then listen to the entire email message; forward or compose a response using verbal instructions. Phone calls, SMS messages, and a number of email attachment types can also be managed. In addition, filters can also be set to priorities mail, so you don't get hassled with that latest sales pitch from an online store.

Double Lane Change Increases SUV Rollover Risk

Drivaware reports on a new double lane-change test that is designed to stimulate an emergency maneuver to determine SUV handling. The test is important because the more controllable and secure a vehicle is when pushed to its handling limits the better chance the SUV occupants will avoid an accident. In situations where an obstacle is in the way, due to the compromising nature of SUVs in general, steering around it can cause the vehicle to go out of control and result in an SUV rollover. Double lane-change SUV rollovers are more common than passenger cars because of the higher center of gravity that makes SUVs more prone to rollover, especially if swerving abruptly.

The aspect of SUV safety has most often focused on risk of rollover. The National Traffic Safety Administration (NHTSA) has said the rate of SUV rollover is two to three times greater than a passenger car. Height of a SUV makes the vehicle more top heavy than one that sits lower, which is why consumers interested in purchasing a SUV are advised to choose one lower to the ground if not needing a vehicle with high ground clearance.

Accident avoidance is an important aspect of vehicle safety and the ability to sharply swerve to avoid hitting an object or a person. In a SUV, the sudden cornering forces or double lane-change can cause the SUV to tip onto two wheels and cause it to rollover. Especially after the Ford/Firestone SUV rollovers in 2000 left hundreds dead and even more injured, focus on SUV safety, like double lane-change SUV rollover risk, greater.
