    • Apparatus and methods are provided for diagnosing faults in multiple, associated motor-resolver systems. One apparatus includes a swapping circuit coupling a first resolver to a first or second decoder, and a swapping circuit coupling a second resolver to the first or second decoder. One method includes applying a signal from a resolver to a first decoder to determine that the first decoder is malfunctioning if the first decoder continues to generate a fault signal, and applying a signal from a different resolver to a second decoder to determine that a motor associated with the first decoder is malfunctioning if the second decoder generates a fault signal. Another method includes transmitting a signal from a resolver to first and second decoders, transmitting a signal from a different resolver to the first and second decoders, and determining if the first decoder, second decoder, a first motor, or a second motor is malfunctioning.
    • 提供了用于诊断多个相关联的电动机 - 解算器系统中的故障的装置和方法。 一种装置包括将第一解析器耦合到第一或第二解码器的交换电路和将第二解析器耦合到第一或第二解码器的交换电路。 一种方法包括:将来自解算器的信号应用于第一解码器,以确定第一解码器是否故障,如果第一解码器继续产生故障信号,以及将来自不同解析器的信号施加到第二解码器,以确定电动机相关联 如果第二解码器产生故障信号,则第一解码器出现故障。 另一种方法包括将来自解算器的信号发送到第一和第二解码器,将来自不同分解器的信号发送到第一和第二解码器,以及确定第一解码器,第二解码器,第一电动机或第二电动机是否发生故障。

    • A method is provided for detecting an insufficient or missing phase current in a permanent magnet synchronous motor, and includes determining a composite vector position of a combined three-phase phase current with respect to a stationary portion of the motor, and assigning a sector to the position. The method includes comparing the phase current to a calibrated threshold current corresponding to the sector, and executing a response when the absolute value is less than the threshold. A vehicle includes an energy storage device (ESD), a motor/generator configured as a permanent magnet synchronous motor, a voltage inverter, and a bus for conducting DC current from the ESD to the inverter. A controller detects an insufficient phase current, determines a current vector position of the three-phase AC, assigns a sector to the position, and executes a response when an absolute value of the phase current is less than a calibrated threshold.
    • 提供了一种用于检测永磁同步电动机中不足或缺少相电流的方法,包括确定组合的三相相电流相对于电动机的静止部分的复合矢量位置,并将扇区分配给 位置。 该方法包括将相电流与对应于扇区的校准阈值电流进行比较,以及当绝对值小于阈值时执行响应。 车辆包括能量存储装置(ESD),被配置为永磁同步电动机的电动机/发电机,电压逆变器和用于将DC电流从ESD引导到逆变器的总线。 控制器检测到不足的相电流,确定三相AC的当前矢量位置,将该扇区分配给该位置,并且当相电流的绝对值小于校准阈值时执行响应。
