#ICYMI: Last week IIHS announced a new safeguard ratings program for partially automated systems. Here’s what it will take to get a good rating. Thread ⬇️ (1/10)
Neither gaze monitoring nor hand position detection is adequate on its own to ensure the driver is paying attention and ready to take over. (2/10)
Evidence shows that the more types of alerts a driver receives, the more likely they will notice them and respond. (3/10)
If these escalating alerts fail to reengage the driver, the vehicle needs to safely respond. (4/10)
Participating in decision making helps keep drivers in the loop, so actions like lane changes should involve driver input. (5/10)
There need to be limitations on when ACC will reengage after a stop. (6/10)
Sharing control of the vehicle helps keep the driver focused. Some systems disengage with driver input, which can discourage drivers from trying to share control. (7/10)
Use of partial automation should be dependent on a driver using the vehicle’s safety features, like the seat belt. (8/10)
This also includes having crash avoidance features active. (9/10)

Driver mistakes play a role in virtually all crashes. That’s why automation has been held up as a potential game changer for safety. But autonomous vehicles (AVs) might prevent only around a third of all crashes if automated systems drive too much like people. 1/8
According to a national survey of crashes, driver error is the final failure in the chain of events leading to more than 9 out of 10 crashes. A new analysis suggests that only about a third of those crashes were the result of mistakes that AVs would be expected to avoid. 2/8
IIHS researchers examined more than 5,000 police-reported crashes. Collected by the National Highway Traffic Safety Administration, this sample is representative of crashes across the United States. 3/8

Thread: Level 2 automated driving systems should include escalating attention reminders to keep the driver's focus from wandering. 1/7
When the driver monitoring system detects that the driver's focus is elsewhere, that should trigger a series of escalating attention reminders. The first warning should be a brief visual reminder. 2/7
If the driver doesn't quickly respond, the system should rapidly add an audible or physical alert, such as seat vibration, and a more urgent visual message. 3/7
