主要产品
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DC(BLDC)电动机——来代替液压致动机构。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功能,在速度较低且最需要辅助的情况下提供较多辅助,在速度较高时提供较少辅助。

BLDC电机解决方案

意法半导体的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。
