An Evaluation of the Forward Collision Warning System and Evasive Steering Maneuvers using a 2016 Volvo XC90

Testing was conducted in daytime conditions at four speeds – 35, 50, 60, and 70 mph – to evaluate the performance of the audible and visual forward collision warning (FCW) component of the collision mitigation system in a 2016 Volvo XC90 while approaching a stationary vehicle target (SVT) in a rear collision scenario. Testing measured the time to collision (TTC) values at the issuance of the FCW, the distance from the test Volvo to the SVT at FCW, and the speed of the Volvo at FCW utilizing Racelogic VBOX data acquisition systems. The results of the testing add higher speed scenarios to the database of publicly available tests from sources like the Insurance Institute for Highway Safety (IIHS), which currently evaluates vehicles at 12 and 25 mph. In addition, the timing and accelerations of evasive steering maneuvers relative to the SVT were quantified.
