Abstract

A procedure that was developed by Honda R&D to measure and evaluate vehicle rollover resistance is described and compared to the NHTSA Roll Rate Feedback Fishhook Test. The Honda procedure, known as the AVC Reverse Steer Test, incorporates the use of an automatic vehicle controller (AVC) for precise and repeatable steering inputs and to allow the use of sensor feedback in the control algorithm. The procedure is intended to induce "worst-case" dynamic roll response for each vehicle, by using the vehicle's roll momentum. A distinguishing feature of the AVC Reverse Steer Test is the algorithm used to determine when the steering reversal is to occur. The reversal occurs at a time corresponding to the second local maximum value of roll rate, following the initial steering input. It was found that this algorithm provided a reversal timing that induced worst-case roll response for a variety of vehicles.
