Recent innovations in automotive engineering have produced active safety systems ranging from side alert, often called blind spot warning, to adaptive cruise control, to collision detection and warning. What this means to the average consumer will change over time as these products become increasingly available. What this means to the automotive engineer is increased attention to safe technology.
Many impressive innovations beyond the now customary car navigation system have existed - and even been on the market - for years now. Adaptive cruise control has been available since the early 19990s. Electronic stability control has been an option for many vehicles since 1995. Scanning radars, crash sensors, pre-crash mitigation and vehicle and occupant safety systems are also emerging. Such systems offer insights into how roads can be made safer in generations to come and where automotive technology is heading. In other words, as cars become "carputers," automotive engineers are driving shifting technologies.
The myriad of promising innovations includes vehicle occupant safety systems. For example, a crash sensor generates a signal based upon a potential crash or one already transpired via a continuously variable severity output signal. If an accident has occurred, sensors signal certain actions like deployment of airbags. If an accident is likely to occur, sensors can alert the driver in various ways so that she or he can try to take necessary actions to avoid an accident and/or the sensors can take action themselves by pretensioning seatbelts or initiating automatic braking. In many ways, this process is not dissimilar to the functioning of the human brain: The brain sends a signal to the body to complete an action, often in response to stimuli received from the outside world. Who knew humanity would serve as its own model for creating devices designed for our safety?
Often, though, such examples of automotive technology are integrated into high-end, expensive cars first, due to high pricing. As the benefits of these products become more widely known and their popularity expands, costs decrease due to economies of scale and advancing technology. As research and development pay off, these advanced products become more widely distributed.
The advantages of automotive system and component integration expertise will continue to increase over time. Such knowledge may be paramount to an industry focused on better fuel economy, safety advancements and financially feasible products. Engineers versed in not only the basics of these systems but also in how to integrate them is only the beginning. Savvy engineers who are engaging in up-integration - adding software that makes one electronic module do many things - and sensor fusion - using complementary technologies to enhance object detection and classification - may have an edge in an ever-competitive job market.
In the rush to meet consumer demand and stay competitive, suppliers tend to be increasingly eager to develop ways to integrate safety and other technology systems. Many vehicles currently come with automatic on/off, high/low beam and rain sensor technology for instance. A separate camera, of course, is not necessary for this. Install a camera for a lane departure warning system, and suddenly a world of possibilities opens up. Intelligent headlight plus pedestrian and sign recognition programs can also be added, to name a few, without the need for additional cameras. Separate module manufacturing for each technological innovation becomes unnecessary. Multiple functions and features on the same apparatus decrease cost and increase functionality
So, what's next? It seems to be the perpetual question that automotive engineers ask - no matter how far we advance. Perhaps an entirely self-driving car. Perhaps hover vehicles on highways, following designated pathways and communicating with surrounding vehicles to avoid crashes.
What do consumers want? The evolution of technology. Inventions born of new ideas. And, ultimately, innovative products that can even make us all safer. It's the engineers, though - the technological innovators themselves - who make it possible.

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.
