The periodic cycles of excitement and disappointment over the emerging future of fully autonomous vehicles sometimes overshadow the reality that our vehicles are steadily getting more intelligent. Blind spot monitoring, which is often standard in new cars, will give you an alert anytime a driver (and maybe even a pedestrian) enters an area that generally represents the vehicle's blind spot. Adaptive cruise control automatically maintains a preset distance to the car in front of you. Lane keep assist varies by vehicle, but in vehicles with electronic power steering, it can nudge your vehicle back between the lane markers if you start to drift too far. Autonomous emergency braking forcefully engages the brakes if your car detects an imminent frontal collision. And a total of eight 2024 models available in the U.S.offer some version of hands-free driving under certain conditions. This is on top of more convenience-focused technologies, like cars that parallel park for you and those with optional one-pedal driving, where the driver brakes and accelerates with a single pedal.
Assistant Professor of Industrial and Manufacturing Systems Engineering Areen Alsaid says these driver assist features have the ability to reduce driver workload and make driving safer. But as an expert in human-technology interactions, she's also been wondering if the learning curve associated with this growing list of advanced features could limit their benefits. "For example, I have a vehicle that has both lane keep assist and adaptive cruise control, and I was under the impression that you couldn't have them both engaged at the same time, but I tried it and I totally could," she explains. "That sort of made it like an AV, because the car was controlling both its speed and lateral orientation within the lanes. I definitely did not expect that." She says sort of like an AV, of course, because, in her vehicle, she discovered these features only remain engaged as long as she has her hands on the steering wheel. But for Alsaid, the experience underscores an important caveat about new driver assist features: When drivers are purchasing a vehicle equipped with several of these advanced technologies, they don't automatically understand how they work, what their limitations are, and if features will interact with each other in ways they find intuitive. It's only once drivers become more familiar with how these technologies function that they can fully reap their benefits.
Alsaid says there is a growing body of research on individual driver assist technologies, but researchers are just scratching the surface on understanding the various scenarios when multiple features are operating simultaneously. As part of a new project funded by Toyota, Alsaid is hoping to build some foundational knowledge in this space by studying how drivers behave as they use multiple longitudinal features - technologies that, as contrasted with lateral features like lane keep assist, control the forward momentum of the vehicle. These include things like adaptive cruise control, one pedal driving, forward collision warning, autonomous emergency braking and hands-free driving at low speeds. In the first stage of her study, she'll observe 10 participants as they engage multiple driver assist features in real vehicles on real roads, monitoring their behavior with cameras and real-time questions, as well as biometrics, like eye tracking and heart-rate monitoring. Using some of the initial insights from this experiment, she and her student research assistants will then design a full driving simulator experience, where dozens more drivers will be confronted with challenging driving situations.
Alsaid says after this initial study, the team will review the results and try to identify areas where the interactions between features and the user interfaces can be made more intuitive for drivers. Her hope is that their work in this area can help drivers adapt more smoothly to these new features so they can enjoy the full potential of their smarter new cars.
