Abstract
本发明提供了一种无位置传感器冗余控制方法及系统、设备、介质，属于汽车线控制动系统技术领域，所述方法包括：获取RPS信号；当RPS信号为无效时，估算电机的转子角度和速度，并输出估算的转子角度和速度以代替RPS信号；基于估算的转子角度和速度进行电机闭环控制。本发明能有效屏蔽瞬时干扰，避免因传感器瞬时故障导致的频繁功能降级，提升用户体验；本发明在传感器真实失效后，提供功能冗余，确保车辆始终具备基础制动能力，消除安全隐患；本发明通过分阶段报码和详细LOG记录，精准定位问题，区分是偶发干扰还是硬件损坏，指导售后维修，降低误换件成本；本发明无需增加或更改任何硬件传感器，即可实现系统可靠性的大幅提升，经济性极佳。
