Real-time dynamic simulation of vehicles with electronic stability control: modelling and validation

摘要

This paper presents an approach to real-time dynamic simulation of vehicles with electronic stability control (ESC). The approach involves the integration of ESC software into the powertrain and brake models of the real-time vehicle dynamic simulation environment of the National Advanced Driving Simulator (NADS). The ultimate goal of this integration is the use of ESC equipped vehicles in simulator based, human factors experimentation, assessing the effectiveness of ESC in avoiding 'loss of control' accidents. The effectiveness of this approach in simulating ESC is demonstrated through the development and validation of two vehicle models, one for a 2003 Ford Expedition and the other for a 2002 Oldsmobile Intrigue, both equipped with ESC. Results show close correlation of vehicle behaviour between the test data and the simulation data. In addition, the timing and magnitude of the simulated ESC activity correlates closely with the test results.
