AAA finds advanced driving assistance still inhaled

Rain can cause serious damage to advanced driver assistance systems (ADAS), according to a new study by the American Automobile Association (AAA). Just as highway traffic slows down in the event of a sudden flood, modern safety devices can cause real problems in practice when fog rains downpour.

Motor club organization on Thursday Announcement of closed course test results This seemed to indicate that some assistance suites had a real problem looking in bad weather. AAA reported that 33% of test vehicles equipped with automatic emergency braking collided with vehicles that stopped when exposed to simulated rainfall at 35 mph. The number of automatic lane keepings was even worse, with 69% drifting off the line. It’s a little substantiated given the number of times the people writing on this website have anecdotally criticized ADAS for cheating in snow, sleet, rain, fog, or because the car is a little too dirty. It’s hard not to feel.

But AAA doesn’t seem to want verification. After years of calm consideration of advanced drive systems, we often come to the conclusion that the industry has released substandard technology on the road. This time around, assessing ADAS under pristine conditions suggests ignoring the reality of having to use these systems 24 hours a day, 7 days a week.

“Vehicle safety systems use sensors and cameras to check for road markings, other vehicles, pedestrians, and road obstacles. Naturally, they are more vulnerable to environmental factors such as rain. “Greg Brannon, AAA’s Director of Automotive Engineering and Industrial Relations, said. “In reality, people are not 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.”

However, I’ve seen enough tests under clear skies with driving assistance. yet Allowed the vehicle to repeatedly hit simulated pedestrians Knowing that it is only part of the problem. AAA has implemented some of them, but the results have not reached what we are willing to leave to our lives. It’s actually surprising to be able to install it on more than 90% of modern cars when there isn’t really a regulatory framework for quality assurance and most objective tests show it to be unreliable. It should be (more expensive). The bluest sky.

Things get even worse when exposed to dark environments and moderate rainfall.Meanwhile, the evidence is increasing Relying on ADAS makes the driver feel dull And you can Encourage a dangerous level of complacency behind the steering wheel.. But today’s systems technically don’t get anything from it. Force you to interact as you are fully engaged It seems that the car does all the work.

A AAA study conducted in collaboration with the Automotive Research Center (ARC) Automotive Club in Southern California used vehicle detectors and windshield-sprayed mounts to simulate rain. Cars tended to have more problems fighting more rain and faster speeds. At 25 mph, 17% of test runs examining automatic emergency braking ended in a crash. At 35 mph, that number has risen to 33 percent. However, it has been reported that the situation improved when the windows were dirty with insect guts and dirt.

From AAA:

During testing with a simulated dirty windshield (bug, dirt, water concentration), there were slight differences, but no negative impact on performance. AAA testing has shown no impact on overall system performance, but ADAS cameras can be affected by windshield stains. It is important for the driver to have his own view and to keep the windshield clean so that the camera of the ADAS system is not obstructed.

Also, some systems may provide or deactivate alerts in extreme situations, but the conditions tested by AAA did not provide such alerts or warnings.

To simulate rainfall, AAA engineers designed a system that uses a reservoir to hold water, a high-pressure pump for constant water flow, and a precision injector nozzle to spray on the windshield. The system was fixed in the cargo area of ​​the test vehicle and connected to a nozzle placed over the windshield so that the spray pattern covered the entire windshield. It should be noted that the water sprayed by this system did not reach the pavement and interact with the tires of the test vehicle.

Outlets suggested that the best way to mitigate risk is to not trust these systems and follow the practice of creating enthusiastic and defensive drivers. It’s also a good idea to know how the system works in your car And it can help create unpredictable scenarios where ADAS becomes blind or tries to make you a little wonder from the road.

“AAA recognizes that these systems have the ability to reduce the likelihood of collisions and improve overall driving safety,” says Brannon. “Tweaking performance and providing a more consistent experience for the driver can be a great help in unlocking the true potential of the driver.”

I’m biased towards consumer advocacy because AAA focuses on consumer advocacy, but this study needs to point out some shortcomings. Due to the limited logistical support of researchers, the test was limited to only a handful of vehicles. However, AAA and ARC sought to mitigate this by sampling various mainstream models around the world with the most popular body styles. Vehicles include the 2020 Buick Enclave Avenir (with automatic emergency braking and lane keeping assist), the 2020 Hyundai Santa Fe (with forward collision avoidance assist and lane keeping assist), and the 2020 Toyota RAV4 (with pre-collision system and lane trace assist). Was there. ), And 2020 Volkswagen Tiguan (with front assist and lane assist).

If you are interested in avoiding aggregated data and want to know how each vehicle worked individually, It is advisable to check the complete investigation.. The same is true if you have questions about how the tests were done or what hardware was used to aggregate the data, as it is so comprehensive. AAA also has related research with a particular focus. Lane keeping function, Driving aids that pedestrians cannot see, When How these systems actually make safe driving difficult..
