Automated Rollover Testing
ASI's Nav™ performs dynamic rollover tests that simulate real-life situations, such as when a driver drifts to the road shoulder and overreacts with extreme steering.

Replacing human drivers with in-vehicle robots has many benefits for automobile testing. Besides the huge increase in test accuracy and safety, allowing a robot to drive the test vehicles allows for entirely new tests that would be impossible with a human driver.

Rollover tests are a perfect example of this. Currently there are a few ways of doing these tests, but most of them are capital intensive and very inflexible.

Cable-pull systems can be rigged to pull a vehicle off a slope or over a tilted ramp, or dollies can carry a car sideways and then stop suddenly, throwing the vehicle off and rolling it.

Cable-pull system tests are capital intensive, often do not accurately depict real-life situations, and require infrastructure changes to modify test parameters.

With ASI's Nav™, car makers and test facilities can perform many types of dynamic rollover tests without endangering a human driver.

Durability and misuse tests attempt to replicate real-life situations that often lead to roll-overs, such as when drivers drift off the shoulder of the road and then over-correct as they turn back.

Nav can replicate these extreme situations in a manner that allows testers to isolate and alter variables without having the build or modify fixed infrastructure.

The National Highway Traffic Safety Administration (NHTSA) specifies what tests are performed on each vehicle, and these tests are constantly becoming more vigorous and will continue on that path. Autonomous Vehicle systems from ASI allow OEMs and test facilities to quickly adapt to these changing standards.
