摘要： The present invention provides an accessory drive system for a hybrid vehicle. The accessory drive system includes an inverter operatively connected to a direct current battery. The inverter is configured to convert the direct current from the battery into three-phase alternating current. The accessory drive system also includes a transmission having a first motor/generator operable to drive the hybrid vehicle. The first motor/generator is a Y-connected three phase motor/generator that defines a first neutral point. A second motor/generator is connected to an accessory and to the first neutral point. Output from the battery is transferable through the first neutral point to the second motor/generator such that the accessory is driven at a selectable rate.

摘要： A method for operation of an internal permanent magnet motor having a rotor includes determining whether a neutral point access signal is received from the rotor and operating the internal permanent magnet motor using sensorless signals corresponding to a rotor position and a rotor speed derived by a first sensorless signal estimation method when the neutral point access signal is received, wherein the first sensorless signal estimation method utilizes the neutral point access signal to generate the rotor position and the rotor speed. The method further includes operating the internal permanent magnet motor using sensorless signals corresponding to a rotor position and a rotor speed derived by a second sensorless signal estimation method when the neutral point access signal is not received, wherein the second sensorless signal estimation method does not utilize the neutral point access signal to generate the rotor position and the rotor speed.
摘要翻译：一种具有转子的内部永磁电动机的操作方法包括：确定是否从转子接收中性点存取信号，并使用与转子位置相对应的无传感器信号和由第一无传感器导出的转子速度来操作内部永磁电动机信号估计方法，其中所述第一无传感器信号估计方法利用所述中性点存取信号来产生转子位置和转子速度。该方法还包括：当没有接收到中性点接收信号时，使用与转子位置相对应的无传感器信号和由第二无传感器信号估计方法导出的转子速度来操作内部永磁电动机，其中第二无传感器信号估计方法不利用中性点存取信号产生转子位置和转子转速。
