The Technology Behind Driver Assist Systems
Today, technology lies at the center of most facets of our lives. The automotive sector might be the most innovative industry, especially with the incorporation of driver assist systems. These systems enhance safety and are making our cars perform better and better. But are these automated systems safe? That is the question this article will explore. The authors will look at the present and potential future of driver assist technology—its use, and its misuse—to argue that it has a greater chance of reducing accidents and increasing driving efficiency than it has of doing the opposite. And with the unfortunate possibility that overreliance and complacency might be our drivers’ garnish, we refuse to let the industry serve up that experience on our plate.
According to the Insurance Institute for Highway Safety (IIHS), automatic braking and other similar driver assist technologies have the potential to decrease the number of rear-end accidents by as much as 50%. That’s a good thing, and it shows the promise of these technologies. However, the IIHS also highlights the potential for over-reliance on these technologies to lead to dangerous situations. A few researchers in automotive safety (including Dr. Emily Chen, quoted above) go so far as to say that some of these systems (especially the more advanced ones that are a step towards actual driving automation) could be giving drivers a “false sense of security.” After all, if driving is becoming safer thanks to all these technologies, then what’s the danger in losing those basic skills that make us good drivers and should also make us drive responsibly?
Understanding Sensors and Cameras in Modern Cars
Driver assist technology is a collection of features that help support drivers. These features include things like blind spot monitors and automatic emergency braking. At the core of these systems is a complex network of sensors and cameras that do the hard work of understanding and interpreting what kind of an environment the vehicle is in. For many vehicles, this entails using both radar and camera-based systems to achieve a baseline understanding of the world. However, the technology isn’t infallible. If the radar or camera system is functioning poorly due to water droplets impinging on the lens or just a very wet vehicle, the system might not be interpreting correctly. The technology can’t replace a human driver, who is quite good at understanding the environment both in and out of the vehicle, and who can work around system impairments.
The Role of Driver Monitoring Systems
To decrease the likelihood of human error, which is responsible for more than 90% of traffic accidents, assistive driving systems have been created. These systems serve to augment human performance, making it safer to travel in today’s cars, especially when human drivers are unfocused or fatigued. They do this by following the driver’s lead and also by using the car’s smart sensors to chalk out a safe driving envelope. For lane-keeping assistance, for instance, the car knows when it is about to cross into another lane and warns the driver. For adaptive cruise control, the car can sense when it is about to inadvertently speed up to a dangerous level. These are some of the safer smart car technologies in the eon of the automobile.
Driver attentiveness monitoring technology is still very new and somewhat crude. Some cars use a basic steering wheel sensor in conjunction with other low-tech monitors (like cameras aimed at the driver) to try and determine whether the driver is ready to take over. But could all of this work better, or work at all, if the steering wheel is literally not part of the driving equation? More advanced systems are needed to ensure safety, and their development raises a crucial question: When will such systems become standard across all vehicles and thus enforce an industry baseline for driver safety? Regulations are another potent factor in calculating the attentiveness of the average driver in an average car today. They represent the decision, by someone, either to ensure system safety or allow system convenience.
Challenges and Concerns with Hands-Free Driving
Some people might counter that driver assist systems are a good bet because they save lives, and that they are headed in an even better direction because they will soon be capable of doing most of the driving with little or no help from a human operator. But what these folks don’t argue—at least not convincingly—is that these systems are safe to use if you happen to be in a vehicle equipped with one. That is what’s at risk here—using these systems safely. And in trying to figure out just how much to trust them, the IIHS and the critics of these systems raise a couple of questions that are worth pondering.
It is very important for the average reader to comprehend the effects that driver assist technologies will have on our society. From what we know now about the capabilities and limitations of current technology, it is evident that we, as consumers and citizens, need to be informed. While driver assist technologies will, and in some cases already do, enhance our driving experience, they must not be thought of as a safe substitute for driving. We must also ask—and start to answer—some hard questions about the liabilities and responsibilities we and the purveyors of these technologies will have, should something go wrong.
Ultimately, driver assist technology is a great leap forward for automotive safety, but this over-reliance on the tech may overstretch its potential benefits, too. According to the IIHS, there is a “potential for reducing driver error,” but we may be tempted to take our eyes off the road too much and substitute ally for a good, old-fashioned attentive driving. Autonomous driving is already starting to happen, but it’s happening on two levels: semi-automated—or SAE Level 2—driving, which consists of features like adaptive cruise control that work together but require constant driver supervision and engagement; and fully automated—SAE Level 5—driving that requires no driver at all. Both progress and complacency are dangerous.
