Driver training for future automated vehicles: introducing CHAT (CHeck, Assess and Takeover)

A new study suggests that behavioural training for drivers is paramount for the transition into the next stage of automated vehicles, known as level 3 automation. Two groups of experienced drivers in a high-fidelity driving simulator were studied to observe their behaviour while ‘driving’ a car with level 3 automation. It was found that drivers who received behavioural training were more measured in their behaviour and better understood the car’s capabilities and limitations. The behavioural training included the provision of a checklist known as CHAT (CHeck, Assess and Takeover). The other group trained by reading an operating manual. During a period of automated driving, participants in both groups could decide whether to engage in a non-driving task, such as looking at their phone, tablet, laptop or reading materials, or nothing at all. When notified by the vehicle to take back control and transition from automated driving, the group who were trained with only an operating manual took almost 10 times longer to pay full attention to driving, continuing glances at their non-driving task for an average of 11.2 seconds, compared with 1.8 seconds in the behavioural group. The behavioural group was also markedly faster at making their first glance at the road when notified to take over – on average 7.3 seconds, in comparison to 21 seconds in the other group. This research demonstrates that the complex and changing nature of the role of the driver in an increasingly automated car should not be underestimated.
