Introduction In the first part of this series, we introduced the operating principles of the Electronic Stability Control (ESC) system, its main components, the sensors it employs, and the way it intervenes to maintain vehicle stability. However, the proper performance of a control system cannot be ensured solely through sound design; it must also be evaluated under real-world driving conditions and critical maneuvers. For this reason, international standards define a set of dynamic test procedures to assess ESC performance. These
