October 14 (Businesshala) – The performance of advanced driver-assistance technology used to help vehicles brake automatically and stay in the lane has been significantly reduced by moderate and heavy rain, the American Automobile Association said on Thursday. One study has shown.
Researchers from the AAA, a consortium of North American motor clubs, found that vehicles’ auto emergency braking systems, in many instances during simulated rain, no longer recognized vehicles stalled ahead and that vehicles’ lane-keeping systems performed significantly worse. has done.
The researchers said this could lead to dangerous situations if drivers rely too heavily on systems whose performance is typically evaluated under ideal conditions.
“The reality is that people don’t always drive in perfect, sunny weather, so we must expand testing and take into account the things that people really struggle with in their day-to-day driving,” says AAA’s Automotive Greg Brannan, director of engineering and industry relations, said in a statement.
Advanced driver-assistance systems, or ADAS, are becoming more common in new vehicles. They do not offer autonomous driving, but can automate limited driving tasks.
Auto emergency braking is increasingly provided as a standard feature in new cars and has been shown to significantly reduce rear-end crashes in tests by insurance groups.
In the AAA study, no test car collided with a stopped vehicle under ideal conditions. But during simulated rain, 17% of test runs resulted in accidents at speeds of up to 25 mph (40 km/h), which increased to 33% at speeds up to 35 mph (56 km/h).
The pavement was dry during the rain test and the researchers noted that wet roads could result in an even higher accident rate.
Vehicles equipped with lane-keeping technology passed lane markers 37% of the time during ideal conditions in the AAA test, but that rate increased to 69% once it rained.
The group tested the 2020 Buick Enclave Avenir, 2020 Hyundai Santa Fe, 2020 Toyota RAV4 and the 2020 Volkswagen Tiguan.
