(Reuters) -The performance of advanced driver assistance technologies used to help vehicles automatically brake and stay in the lane is significantly reduced by moderate and heavy rains, a study by the American Automobile Association Thursday. It was shown to.
Researchers at AAA, a federation of North American motor clubs, found that the vehicle’s automatic emergency braking system no longer recognizes vehicles stopped in front during simulated rainfall, significantly reducing the performance of the vehicle’s lane keeping system. discovered.
If the driver is overly dependent on the system, it can lead to dangerous situations. System performance is usually evaluated under ideal conditions.
“In reality, people aren’t always driving in perfect sunny weather, so we need to expand our tests to take into account what people actually face in their daily driving,” AAA said. Greg Brannon, Dean of Automotive Engineering, said. Industry relations were stated in a statement.
Advanced Driver Assistance Systems (ADAS) are becoming more common in new vehicles. We do not offer autonomous driving, but you can automate limited driving tasks.
Automatic emergency braking is increasingly being offered as a standard feature on new vehicles and has been tested by insurance groups to significantly reduce rear-end crashes.
In a AAA study, no test car collided with a vehicle that stopped under ideal conditions. However, during the simulated rainfall, 17% of the test runs caused a crash at a speed of 25 mph (40 km / h) and increased to 33% at a speed of 35 mph (56 km / h).
The pavement during the rain test was dry, and researchers pointed out that wet roads could result in even higher collision rates.
Vehicles equipped with lane keeping technology had a 37% chance of passing the lane marker in the ideal state of the AAA test, but when it rained, that percentage jumped to 69%.
The group tested the 2020 Buick Enclave Avenir, the 2020 Hyundai Santa Fe, the 2020 Toyota RAV4, and the 2020 Volkswagen Tiguan.
