(Reuters) – The performance of advanced driver assistance technologies used to help vehicles brake automatically and stay in the lane is significantly reduced by moderate and heavy rain, a study by the American Automobile Association reported on Thursday. was shown to.
Researchers from AAA, a consortium of North American motor clubs, found that the vehicle’s automatic emergency braking system no longer recognizes vehicles parked in front during simulated rain, significantly reducing the performance of the vehicle’s lane keeping system. searched for.
If the driver is highly dependent on the system, it can lead to dangerous situations. Evaluation of system performance is usually done under ideal conditions.
“In fact, people don’t always drive in perfect sunny weather, so we need to expand our tests to take into account what people actually encounter in their daily driving,” AAA said. . said Greg Brannan, Dean of Automotive Engineering. Industry Relations was said 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 reduce rear-end crashes.
In the AAA study, no test car collided with a vehicle that stopped under ideal conditions. However, during simulated rain, 17% of test runs caused accidents at speeds of 25 mph (40 km/h) and 33% increased to speeds of 35 mph (56 km/h).
The pavement was dry during the precipitation test, and the researchers reported that wet roads could result in an even higher collision rate.
Vehicles equipped with lane keeping technology had a 37 percent chance of passing the lane marker under ideal conditions for the AAA test, but when it rained, that percentage increased to 69%.
The group tests the 2020 Buick Enclave Avenir, 2020 Hyundai Santa Fe, 2020 Toyota RAV4 and the 2020 Volkswagen Tiguan.
