Automatic braking systems can go by many names, a practice that may confuse buyers. But consumers should be aware that some models with collision avoidance systems can actually stop a car in time to prevent crashes, according to a new Insurance Institute for Highway Safety study.

The IIHS, which ranks vehicles with crash tests, has started rating these systems with non-crash tests to see if cars stop before a collision, USA TODAY reported.

"This technology is moving into the market surprisingly quickly. It's good to see," said David Zuby, IIHS chief research officer, as quoted by USA TODAY.

"It can get very confusing" since automakers use a variety of names to designate crash detection systems, Zuby said. Some examples include Audi's "Pre-Sense Front;" BMW's range of offerings such as "Collision Warning with City Braking;" as well as General Motors' "Automatic Collision Preparation" and "Collision Mitigation Braking."

The latest non-crash test score card was announced on Thursday, following tests last September and later last year.

The IIHS examined 24 models, ranking eight as "Superior," which is the highest rating. Vehicles with Superior scores had systems that stopped the cars in time to prevent crashes at both 12 mph and 25 mph, USA TODAY reported.

Vehicles could also receive ratings of "Advanced" or "Basic." The latter served to designate cars that don't stop short of a collision but do minimize the impact during a crash.

Around 90 current models have automatic braking systems, which typically use a flashing light or audible signal to warn the driver, before halting the car if the driver doesn't use the brakes. The systems are generally found in package options beyond a model's basic trim level.
