Computer aided engineering (CAE) methods have been part of Electronic Stability Control (ESC) system development since its introduction to the market in 1995, especially in the testing and verification phase. Over time, additional CAE tools and methods have been introduced, ranging from small self-learning algorithms to automatic tuning tools for individual functions. Since the end of 2009, ECE regulations have allowed the use of CAE methods for ESC homologation, and in North America, the exemption from FMVSS126 compliance for aftermarket parts was phased out in 2012. Following these legislative changes, several original equipment manufacturers, aftermarket companies and ESC suppliers are using vehicle dynamics computer simulation methods to predict ESC performance and homologate vehicles.
