Research performed by the AAA discovered that moderate to heavy rain can have extreme influence on motorist help and car security systems’ capability to run properly.

The association, with aid from the Automobile Club of Southern California’s Automotive Research Center, simulated rain and other ecological aspects at a closed course to evaluate their capability to work in less than perfect conditions. It checked functions like automated emergency situation braking and lane-keeping help and discovered that simulated moderate to heavy rain adversely impacted their performance.

In aggregate, screening of automated emergency situation braking systems performed at 25 miles per hour (40 km/h) in those conditions led to an accident with a stopped lorry 17 percent of the time. Checking performed at 35 miles per hour (56 km/h) led to a crash 33 percent of the time.

Lane-keeping help systems fared much even worse. Evaluating discovered that the systems enabled an automobile to divert beyond its lane 69 percent of the time in aggregate.

““ Vehicle security systems count on video cameras and sensing units to see roadway markings, other vehicles, pedestrians, and highway barriers. Naturally, they are more susceptible to ecological aspects like rain,” ” stated Greg Brannon, AAA’’ s director of automobile engineering and market relations. “ “ The truth is individuals aren’’ t constantly driving around in ideal, bright weather condition so we need to broaden screening and take into account things individuals in fact compete with in their everyday driving.””


Although some automobiles do supply an alert or deactivate their motorist support systems in negative conditions or if their sensing units are jeopardized, none of the systems in AAA’s test informed motorists to their problems.

““ AAA acknowledges these systems have the capability to minimize the opportunity of a crash and enhance the total security of driving,” ” continued Brannon. ““ Fine-tuning their efficiency and offering chauffeurs with a more constant experience will go a long method in opening their real capacity.””


The company recommends that chauffeurs must end up being more acquainted with the manner in which these systems work and, more to the point, their limitations. It recommends that chauffeurs must keep their windscreens tidy and make sure that wipers are not spotting, boost following range, and not utilize cruise control in bad weather condition so regarding stay more alert.
