Ultrasonic Sensor Parking System are becoming more commonly fitted to vehicles, but how do they work? Can a car’s design affect installation and will they look factory fitted?

How Do Parking Sensors Work?

As the car reverses into a space and moves closer to objects, an audible buzzer beeps more frequently.

This is usually achieved by four ultrasonic parking sensors fitted into the bumper of the car. They send out an ultrasonic wave, and if this hits an object, it bounces back to the same sensor. Information received is then relayed to the brain, allowing it to make the buzzer sounds.

Will Bumper Design Dictate Installation?

For most vehicles the shape of the car will determine where sensors are fitted. This is due to wide differences in design, between manufacturers and models of vehicles.

For cars with a center panel and separate corner bumper pieces that curve around the car, two low and two higher sensors are often necessary. If a vehicle has a metal panel behind the bumper, this usually means holes must rise above the obstruction, also avoiding interference issues.

What are the Differences Between Factory and Retrofit Fit?

Factory fitted parking sensors are the ones fitted to a car at the time of manufacture. Retrofit, often called ‘After-market’, are the ones fitted at some time after the vehicle was produced.

Factory fitted sensors have a certain look, devised by the car designer, which is difficult to recreate in aftermarket sensors. Retrofit devices are made for all cars from all manufacturers, and consequently have their own distinctive look.

It could be argued that some of the latest aftermarket designs are better due to their small, discreet shape. They are also constantly being redesigned for better looks or usage, and not devised and forgotten like factory ones.

What Size?

Sensor heads are getting smaller. Small is definitely less intrusive although they may have limited colour options, for example only available in black or silver.

Generally it is best to go for the smallest sensor heads possible, as once a hole is drilled it cannot be made smaller.

Do I Need Front Parking Sensors?

Factory fitted front parking sensors are integrated into the vehicle’s ECU. They will automatically switch on, and instinctively sense if you begin a parking manoeuvre. Aftermarket versions, with the same functionality, can be expensive and are not available for all vehicle models.

A realistic option for front sensors is to use a switch. This avoids the system becoming active when moving slowly, for example in a traffic jam, but means the driver switches on the system before beginning to park.

It is also worth noting that generally drivers can see the front of their cars. This means that while rear parking sensors are a significant help when parking, the gains from front ones are limited.

The Head-up Display (HUD) a safety device that is only in some cars and should be in all cars, instead of drivers looking down at the dashboard. The speed, temperature and any warning is projected out through the windscreen and across the bonnet. The driver can look through it and still see the road ahead and other traffic or animals or pedestrians coming to cross the road ahead. With the cost of electronic hardware falling, as shown by low-cost GPS devices, there is no reason why low-cost head-up displays cannot be manufactured and installed in all cars, vans, trucks and buses. The message is safety first.

Why does it take the Governments so long to get the message, after decades of use in military fighter jets, helicopters and transporters the case for making it law is compelling and needs action to encourage wider usage by all drivers. Governments show accident films on TV to discourage drink driving, but seem to be missing the point about car HUD. Since anything that helps keep the driver more awake and aware must reduce accidents.

Maybe it’s the cost of training drivers or getting them to pay more for their cars is seen as a vote looser and therefore the Governments are reluctant to enforce the use of HUDs in as many cars as possible. Drivers wearing glasses or contacts can still see through the projected HUD display and there is no reflection. The projected beam can sense light changes and adjust to meet different conditions and enhance drivers vision and safety.

Your vehicle darts along the road, continuing to speed faster and faster. You press on the brakes, and discover you’ve lost control over the vehicle’s breaking system! Seconds later, you hit a wall. Proving Newton’s law that “for every action there is an equal and opposite reaction,” your head whips back against the headrest. The airbag, which ballooned on impact, cushions your head. With your cranium buried in the inflated airbag, you feel like a dummy, and that is precisely what you are – a crash test dummy. To optimize what they could learn from you, researchers had placed a video surveillance camera on the wall. Such car camera remain useful throughout the life of an automobile.

The Production

From start to finish, the production of an automobile is a very precise and meticulous process. Video surveillance cameras are vital in ensuring that quality control is always maintained. They are mainly used for inspecting many parts, verifying that parts have been positioned properly and in 3D guidance of robots. For instance “smart” cameras are frequently used in various stages of automobile production. The camera helps robots “learn” certain parts. The robots, in turn, use a “vision processor” to verify that a correct product has been installed.

Along an automobile assembly line, video surveillance cameras are also used to monitor the totally automated installation of the windshield and rear-window. Cameras ensure that parts, such as panels, have been positioned accurately onto the vehicle’s body.

The Testing

Many tests are conducted on automobiles. These are carried out to improve their quality and safety. One example is the crash test. High speed cameras, which can capture more frames per second than other cameras, are used. The camera helps to detail what happens to the passenger and automobile during the crash. Due to the high cost of crash tests, these cameras are invaluable in helping researchers obtain as much data as possible from the test. A video surveillance camera can be used for other types of tests on cars. For example, the road test checks whether or not the car is worthy to be driven on roads. Lastly, a video surveillance camera can be used to enforce quality control at emissions test centers, where the amount of pollutants that a vehicle produces is tested.

The Protection

In addition to assisting in the production and testing of automobiles, video surveillance cameras can also be used to safeguard automobiles from auto theft, a grave problem in America. Consider the following statistics.

* Every year, over one million vehicles are stolen in the United States.

* In 2005, the 2001 BMW M Roadster was the most frequently stolen passenger vehicle in the United States.

* In 2006, more vehicles were stolen in Las Vegas than in any other metropolitan area in the United States.

Mounted in places such as driveways, parking lots, parking garages, and car alarm stores, video surveillance cameras are valuable in protecting one’s investment. In addition to capturing visual evidence against car thieves, they also serve as a deterrent for those who are thinking about taking someone else’s Jaguar, Road Runner, or Bug.

There is no doubt that from the assembly line to the junkyard, video surveillance cameras shift gears to play vital roles in the lives of automobiles – choose yours at Car Camera Singapore.

More motorbike owners are biting the in-car camera trend. In recent months, sales of these electronic video recording devices have gone up by 30 percent.

To promote use of these electronic eyes, Insurance giant NTUC Income offers a $100 discount on insurance premiums when policyholders submit video recordings that help settle a claim, regardless of which party is liable. It said that more claims are accompanied by video – about five percent now compared to three percent a year ago.

Speaking to The Straits Times, Vice President of NTUC Income’s Motor Insurance, Peh Chee Keong, said video evidence comes in handy when there are discrepancies in statements, and can help the company when fraud is suspected.

Statistics from the Traffic Police show that the number of fatalities from motorcycle accidents fell by almost 30 percent over the past three years, even as the number of registered motorcycles has remained constant at around 144,000.

The total number of traffic violations committed by motorcyclists, however, increased from 21,032 in 2012 to 26,640 last year.
