A new study reveals that prompts within partially automated driving systems can effectively engage drivers and ensure they take control when needed. However, the study also highlights a critical issue: deeply distracted drivers remain unresponsive to these prompts, posing a significant safety risk.
A new study finds that prompts do a good job of getting drivers to engage with their environment and take over control of the vehicle when necessary while using partially automated driving systems -- with one exception. If drivers are deeply distracted, these system-generated prompts have little or no effect.
"Drivers still need to be aware of their surroundings and be able to take control of the vehicle at any time, in order to deal with system failures or other unexpected situations," says Jing Feng, corresponding author of a paper on the work and a professor of psychology at North Carolina State University."Ensuring that drivers are engaged and able to assume control of the vehicle is a significant challenge.
To assess the effectiveness of conversational prompts at maintaining driver engagement, the researchers conducted two experiments. "We asked the participants in Experiment 2 to solve anagrams because that is a non-driving-related task that is cognitively demanding," Bai says."And it made a significant difference."
"Processing driving-related information is clearly valuable at helping maintain driver engagement," says Feng."However, our findings also underscore the importance of having drivers maintain the proper cognitive workload when driving with partially automated systems. "Another takeaway message is that even these prompts are insufficient to improve driver performance when drivers are cognitively engaged in demanding non-driving-related tasks," Bai says."Additional research is needed to see what, if anything, can be done to mitigate these situations."New research found that driving skills measured at the time of licensure on a virtual driving assessment , which exposes drivers to common serious crash scenarios, helps predict crash risk in ..
