通过辅助驾驶员控制车辆方向盘，电动助力转向（EPS）系统改善了方向控制和乘客安全性，同时减少了引擎负载，从而提高了燃油效率。

电动助力转向（EPS）系统使用电机——通常是三相无刷直流（BLDC）电动机——来代替液压驱动机构。EPS可以改善驾驶员对车辆的方向控制，减少引擎负荷，从而提高其燃油效率。它还可以实现可变辅助力功能，在车速较低时提供较大辅助力，在车速较高时提供较小辅助力。

ST的EPS解决方案包括用于驱动BLDC电机的全系列三相栅极驱动器和功率MOSFET，包括用于48 V范围。专用电源管理IC和CAN收发器，以及各种灵活创新的、应用特定的标准产品（ASSP），涵盖任何可能的系统分区。SPC5 32位汽车微控制器提供整体系统控制。
