The invention discloses a three-phase symmetric brushless EPS controller, which relates to the field of EPS controllers and comprises an MCU, a power management module, a relay protection module, a pre-driving module, a driving power module, a communication module, an end voltage acquisition module, a torsional angle sensor sampling module, a temperature acquisition module and a PCB. According to the invention, three-phase current flows through symmetrically, so that the rotation and reversing of the control motor are more stable and smooth, the vibration and noise of the motor are reduced, and the steering hand feeling and the driving comfort are greatly improved. Meanwhile, through the three-phase symmetrical design, the product consistency is greatly improved, and the production and maintenance cost is reduced.

    本发明公开了一种三相对称式无刷EPS控制器,涉及到EPS控制器领域,包括MCU、电源管理模块、继电保护模块、预驱动模块、驱动功率模块、通讯模块、端压采集模块、扭角传感器采样模块、温度采集模块和PCB板。本发明流过三相电流对称,使得控制电机转动及换向更加稳定顺滑,减小电机振动及噪音,极大的提高了转向手感和驾乘舒适性。同时通过三相对称式设计,也极大的提高了产品一致性,降低了生产维护成本。
