Recent AAA research examined various simulated collisions across four popular 2023 modelyear vehicles equipped with reverse automatic emergency braking (AEB) with rear cross traffic mitigation.
The Inquiry

Reverse automatic emergency braking (AEB) systems have been shown to significantly reduce rearend collisions. Reverse AEB with rear cross traffic mitigation systems are designed to mitigate or prevent collisions with other vehicles, with some reverse AEB systems detecting rear crosstraffic and automatically applying brakes in response to other cars, pedestrians, cyclists or stationary objects. AAA Engineers wanted to know how reverse AEB systems perform when 1) backing out of a parking space into the path of an oncoming vehicle with an adjacent parked vehicle blocking the view. And 2) while encountering a stationary child pedestrian behind the vehicle.
The Results

1) Reverse AEB systems automatically applied brakes in 65% of test runs and prevented a collision in 2.5% of test runs in the context of the backingup scenarios involving a subject vehicle crossing behind the test vehicle. 2) With the stationary child target behind the test vehicle, reverse (AEB) automatically applied brakes in 75% of test runs and prevented a collision in 50% of test runs.

1) Drivers should not rely on reverse AEB systems to prevent collisions when backing up but utilize backup cameras and other sensors to enhance their awareness. 2) Back up cautiously when an object obstructs the view, allowing the ADAS sensors to “see” or detect cross traffic, giving the system more time to see a potential collision and to bring the vehicle to a stop. 3) It’s important to make sure these systems are working properly and repaired accurately.

It was determined that all test vehicles would be small to medium SUVs due to the popularity of these categories. The “2023 Hyundai Tucson Hybrid”, The “Limited AWD 2023 Lexus RX 350 “Premium,” The “2023 Mazda CX30 2.5 Turbo AWD “Premium Plus Package” and the “2023 Volkswagen Tiguan 2.0T “SEL RLine.”
