    • This invention provides methods for electric vehicle motor control and rotor position detection and fault-tolerant processing. The rotor position signal sampled by the system is compared with the previous rotor position θ0. When there is a sudden change, the current position signal acquired is discarded. Instead, a fault-tolerant processing strategy for use during an error condition is employed where the previous sampled rotor position θ0 is used as a base to determine the corrected current rotor position angle Θ1′. Then the correcting value is used to control the electric motor. Thus, during the motor operation, when the detection of the motor rotor position is erroneous because of a sensor such as a revolver that may be interfered by external conditions such as electromagnetic fields or vibrations or when there is a breakdown in other related hardware components or transmitting circuits, the fault-tolerant processing methods of this invention can effectively prevent the motor from losing control and allow it to maintain its continuity and stability.
    • 本发明提供电动车辆电动机控制和转子位置检测和容错处理的方法。 将系统采样的转子位置信号与先前的转子位置进行比较; 0。 当发生突然变化时,取消当前位置信号。 相反,采用在错误状态期间使用的容错处理策略,其中先前采样的转子位置和角度0用作确定校正的当前转子位置角度θ1'的基准。 然后使用校正值来控制电动机。 因此,在电动机运转中,当电动机转子位置的检测由于诸如电动机或振动之类的外部条件等受到干扰的左轮传感器或者其他相关的硬件部件的故障而导致错误时, 传输电路,本发明的容错处理方法可以有效地防止电机失去控制并使其保持其连续性和稳定性。
