Automotive Engineers Help Save Lives And (porsche race car) Cash

It turns out all those fancy automotive safety devices cannot only help save lives, they can also save cash. According to The Economic Impact of Motor Vehicle Crashes, roughly $230.6 billion was exhausted on motor vehicle crashes in 2000 in the U.S. Nearly 42 thousand people perished that year, and 28 million vehicles were damaged.

The same government report also revealed that 5.3 million individuals suffered non-fatal injuries, 39% of all traffic-related deaths were attributed to alcohol and such substance-induced accidents cost about $51 billion. Public tax revenues, amounting to $21 billion, paid the costs incurred by 9% of crashes. That’s $200 for each household in America.

But wait. There’s more. Lost market productivity was estimated at $61 billion, property damage at $59 billion, medical expenses at $32.6 billion and the cost of travel delays at $25.6 billion. Each fatality produced a discounted lifetime cost of approximately $977,000.

Active and passive safety systems developed by automotive engineers and their colleagues may be a bigger part of the answer than we might suspect. Systems currently being developed are addressing both the monetary and safety concerns of our roadways through devices that have automatic responses to dangerous conditions or events. For instance, adaptive cruise control adjusts the speed of the vehicle to maintain a preset time gap from the vehicle ahead. Active night vision uses infrared illuminators to help drivers to see better when driving at night and electronic stability control improves the safety of a vehicle’s handling, helping the driver maintain control of the vehicle.

Surprisingly, perhaps, these are just basic safety features - ranking amongst car navigation systems, keyless entry and hybrid cars as, yes, technological innovations, but old news to vehicle manufacturers. Lane departure and forward collision warning, pre-crash mitigation systems, side alert, pedestrian and road sign recognition systems are part of the new wave. These systems “read” the road using electronics, cameras and sensors. They alert drivers when they are drifting out of the intended lane, have another vehicle in their blind spots, are in danger of crashing or are distracted. These technological gems even respond to unavoidable crashes by enacting safety precautions, such as pretensioning motorized seat belts and applying brakes during the last 400 to 500 milliseconds before a crash, when there is little a driver can do to stop it.

According to the National Highway Traffic Safety Administration (NHTSA), 50% of all crashes involve “driver inattention.” It’s impossible to pinpoint how many crashes could have been avoided if there had only been some alert system warning drivers to pay more attention during critical moments. How many crashes could have been avoided by a single alert, some notification that another vehicle was in a driver’s blind spot? By shaving off four or five miles per hour before a crash by applying the brakes?

And while saving lives and preventing injuries is of the most concern, we cannot, in all reality, ignore the financial repercussions of roadway accidents. Billions upon billions of dollars are lost every year because of these crashes. Medical expenses, property damage and lost productivity are passed on to the average citizen in the form of higher taxes and insurance premiums. What if some percentage of this cost - even if slight - could be lessened by safety systems? One percent of hundreds of billions of dollars, after all, is nothing to scoff at.

Automotive engineers are critical contributors to advancing projects with aspirations of making roads safer. Without their expertise, none of the technology currently available would have been possible and neither would future innovations. What’s more, these talented individuals are integrating these devices so they are more affordable and, thus, more accessible to the masses.

In the near future, a modestly priced vehicle could have a myriad of safety features - forward collision and lane departure warning, road sign and pedestrian recognition, adaptive cruise control, pre-crash mitigation, electronic stability control, side alert. All of it. So kiss some automotive engineers today - hiding in their offices - and tell them you’re proud. They could just save your life … and at least a few bucks on your insurance policy.

“Carputers” Becoming Options On The Open Market
By Mike Trudel

If your fingers itch for a touch screen even during the morning commute, there may be a solution — particularly when you’re carpooling in the passenger seat and have a minute to play. Vehicles are now being released with “carputers” or “carPCs” as an option, not just as a retrofit. A familiar type of “carPC” to most folks is a Global Positioning System (GPS). According to an online encyclopedia, a GPS device is much like a limited laptop running GPS software.

Basic Specs and Tech:

“Carputer” machines consist of a motherboard, processor and memory and data storage method, such as a hard drive or solid state flash memory. Interface hardware depends on non-distracting options to interact with the “carPC,” such as wireless protocols, which are commonly used to connect to GPS devices and mobile phones. Wirelessly connecting and transferring data to and from home computers is also possible.

A well-executed interface is paramount to the machine’s success, and its software runs the computer’s hardware. Good programming allows drivers to use their favorite piece of technology without being distracted. Common operating systems are available and nearly all are customizable.

Making sure “carPCs” keep their juices flowing is a slightly more complicated matter than it is for the average desktop or laptop. The danger lies in the sudden power drain to certain systems that occurs upon start-up or, of course, when the ignition is cut. To suddenly seize a computer’s supply, however, is risky; software can malfunction and data can be lost. To safeguard against this, a DC-DC power supply is often used, which provides a continuous, 12V power stream to the “carputer.” A DC-AC inverter can also be installed, but it tends to use more energy and produce more wasted heat. The right hardware and software combination allows the computer to sense when the main power source has been cut and use what’s left to safely shut down the machine.

Experiments have found that Internet users experience marked levels of frustration when a Web site takes thirty or more seconds to load. Bearing this in mind, imagine how quickly “carputer” popularity would decline without the relay circuits enabling the machine’s devices to start automatically. Without properly relaying circuits, devices such as amplifiers and screens would have to be started manually — something a portion of the general public doesn’t even know how to do anymore.

Before 2000, LCD character displays were the screen of choice for “carPC” builders. Commands were usually sent to the machine through a keyboard with this system. Soon, wireless serial port remotes were made possible, and small television screens became affordable. The majority of first screens were video input only. For over a grand a pop, though, these were hard to justify. Rapidly advancing technology and production increases have recently made touch screens available and affordable.

Lest one thinks these little “carputers” are all business, entertainment features have been added. “CarPCs” now bring nearly all the entertainment comforts of home onto that cross-country trek. Passengers feel like watching a movie? No problem. Playing a video game? Hook ‘er up. Download favorite music, tune in to satellite radio and map the next trip to Europe on advanced GPS software. It’s all there. No more “Maaa-om. Are we there yet?” “Pop in a movie,” says Maaa-om. Or, “do your homework,” which she downloaded from a desktop at home. At last — technology not only brings hope for peace and quiet but also a way to make sure no one gets too lost along the way.

The possibilities are nearly endless. After all, automobiles have already been introduced to the world of high technology. Consider infrared cameras, a variety of hands-free applications, cargo detectors, lane departure and side (blind spot) warning software — these technological offerings are all not only possible but are already being incorporated. Imagine the capabilities modern computers possess. Now imagine that in your car.

Consumers Demand Control Through Human Machine Interface Technology
By Mike Trudel

”Human-Inter-what?” clipped Simon, peeking over his morning paper with a loud crinkle. A favorite farmer of seventy-eight years at my local coffee shop, Simon never failed to give me the truth precisely as he saw it. I had asked him what he thought of Human Machine Interface Technology. “Sounds like science fiction to me. Don’t we already interact - interface, whatever - with machines? How else are we supposed to run the things?”

I laughed, but in a down-to-earth, back-to-common-sense way, Simon was right on. One encyclopedia explains Human-Machine Interface (HMI) technology, also known as user interface technology as the whole means by which human users interact with a particular system, such as a device, computer program or machine. HMI provides a mechanism by which users can input or manipulate a system, and provides the system a way to output or produce the effects of the users’ manipulation.

It’s not really so complicated. HMI is a broad term describing the “layer” between a person interacting with the machine and the machine itself. Applications are varied - from medical prostheses, such as cochlear implants, to computer-human interactions to the operation of vehicular Global Positioning System (GPS) devices.

For example, Web-based user interfaces accept input and provide output by generating Web pages transmitted via the Internet, which are then viewed by users through Web browser programs. Different implementations are utilized to provide real-time control in a separate program, effectively abolishing the need to refresh a traditional HTML-based Web browser.

The more exciting technologies include touch interfaces, which serve as excellent examples of the public’s increasing demand to be in control of their environment and their machines. Touch interfaces are graphical user interfaces using a touch-screen display as a device for both input and output.

This insistence is becoming apparent in the automotive industry, where consumers are demanding to be well-connected and in control. Most vehicular GPS devices, for example, are touch interfaces. Steering wheel controls can also use HMI technology to keep drivers connected through different wireless and electronic apparatuses. Certain corporations are even releasing vehicles in which much of the cockpit is run by HMI technology, such as reconfigurable instrument clusters, reconfigurable head-up displays (HUD), warning systems and multifunctional controls.

The trend seems to be in fewer gauges - reducing six-gauge systems, for example, to fewer with reconfigurable displays. There may be more use of a center cockpit, touch screens and reconfigurable thin film transistor (TFT) displays in the future, as well.

A report about HMI technologies stated the importance for designers to understand that HMI determines an operator’s perception about a machine. Designers are of vital importance, it went on to say, because operators need to be able to trust the apparatus - and trust their interactions with it - in order to make the technology successful. How skillful and mindful HMI designers are in their work will, in large part, determine that. HMI empowerment will come through ease-of-use features, ease of programmability, easy understanding and clear information displays.

According to that study, a portion of the designer population still considers HMI just a tool, but many technologies with vital benefits are poised to make HMI the central command station for monitoring and control operations. This technology has the power to transform equipment into better interactive instruments.

Focus will increasingly be on the integration of hardware and software across horizontal and vertical lines, as well as on security issues associated with HMI software, supervisory control and data acquisition (SCADA) systems. Escalating complexity and the high volume of connections requires this to be of current and future concern. Likewise, agility and portability are proving to be important trends in human-machine interaction and user experience research.
