advanced driverassistance systems or adas are becoming more common in newer vehicles they do not offer autonomous driving but can automate limited driving tasksthe performance of advanced driverassistance technology used to help vehicles automatically brake and stay in lanes is significantly reduced by moderate and heavy rain a study by the american automobile association showed on thursday researchers at aaa a federation of north american motor clubs found that vehicles auto emergency braking systems in several instances during simulated rainfall no longer recognized stopped vehicles ahead and that vehicles lanekeeping systems performed considerably worse advt that could lead to dangerous situations if drivers rely too heavily on the systems whose performance is typically evaluated in ideal conditions the researchers said the reality is people arent always driving around in perfect sunny weather so we must expand testing and take into consideration things people actually contend with in their daytoday driving greg brannon aaas director of automotive engineering and industry relations said in a statement advanced driverassistance systems or adas are becoming more common in newer 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 shown to significantly reduce rearend crashes in tests by insurance groups in the aaa study no test car crashed into a stopped vehicle under ideal conditions but during simulated rainfall 17 of test runs resulted in crashes at speeds of 25 mph 40 kmh increasing to 33 at speeds of 35 mph 56 kmh the pavement during the rain tests was dry and researchers noted wet roads could result in even higher crash rates vehicles equipped with lanekeeping technology crossed lane markers 37 of the time during ideal conditions in the aaa test but that rate jumped to 69 once rain was added advt the group tested a 2020 buick enclave avenir a 2020 hyundai santa fe a 2020 toyota rav4 and a 2020 volkswagen tiguan also readouster will buy sense photonics drive for more automotive dealslidar sensors build a detailed picture of a vehicles surroundings using laser light tesla aside most automakers and autonomous vehicle developers are using lidar as part of the sensor arrays in their automated driving systemssee more details reuters published on oct 15 2021 at 0802 pm ist telegram facebook copy link be the first one to comment comment now comments comment now read comment 1 all comments post post find this comment offensive choose your reason below and click on the submit button this will alert our moderators to take actions reasons for reporting foul language defamatory inciting hatred against a certain community out of context spam others report join the community of 2m industry professionals subscribe to our newsletter to get latest insights analysis download etauto app get realtime updates save your favourite articles scan to download app adas driverassistance technology automation smart technology american automobile association auto emergency braking homenewsautomotiverain impairs performance of driverassistance technology
