Description

双三相BSG电机容错运行方法
技术领域
本发明涉及电机控制领域，具体为一种双三相BSG电机容错运行方法。
背景技术
三相故障的检测，目前可以实现如下几种：
1. 功率器件短路，检测方法：某一相电流超过设定阈值；
2. 功率器件断路，检测方法：某一相电流无法正常输出，系统可以通过检测三相的电流波形正弦度及相位；
3. 电路对地短路，检测方法：三相电流之和是否为0。
现有BSG系统及BSG电机由于还未大面积应用，其系统可靠性和稳定性没有得到充分验证并达到理想的状态，尤其是功率器件部分，是BSG电机故障的主要来源。并且配备BSG系统的车辆依然属于传统车范畴，但是其传统发电机已经由BSG电机替代，即BSG电机既需提供BSG轻混功能，也需要满足车上用电器的供电需求。
在该架构下，当前的很多应用是：一旦BSG电机出现故障，为了驾驶安全性，系统一般直接上报BSG系统故障，并且停止BSG系统的工作，包括BSG电机发电功能也因此被停止。即BSG电机的故障可以直接导致整车的12V系统馈电，因此车辆需要马上进行维修，车辆在BSG电机故障情况下的跛行能力非常有限，对于驾驶员的人身和财产安全产生重大影响。
发明内容
为了克服现有技术的缺陷，提供一种反映灵敏、控制精确的电机控制方法，本发明公开了一种双三相BSG电机容错运行方法。
本发明通过如下技术方案达到发明目的：
一种双三相BSG电机容错运行方法，其特征是：按如下步骤依次实施：
① 识别：当双三相BSG电机控制器的故障监控系统识别到双三相BSG电机中的任意一相中有故障发生，且该故障还仅局限于其所在三相中，并未导致其他部件损坏情况，
② 停止混动：双三相BSG电机控制器及时停止BSG混动系统的混动功能，并发送该故障信息给BSG混动系统，
③ 切换：双三相BSG电机控制器切换控制模式，从双三相控制切换为单三相控制，并且限制功率输出；在容错模式下，单三相控制模式的输出功率满足整车车上用电器的用电需求，提升双三相BSG电机在故障下BSG混动系统的容错运行能力，缓解BSG电机失效带来的BSG混动系统失效和整车馈电影响，以保障驾驶人员的人身财产安全。
所述的双三相BSG电机容错运行方法，其特征是：
步骤①时，双三相BSG电机中的任意一相的故障包括功率器件短路、功率器件断路和电路对地短路中的至少一种；
步骤②时，BSG混动系统的混动功能包括助力、能量回收和自动起停。
本发明可以让双三相BSG电机在功率器件发生故障的情况下，通过系统设计实现双三相BSG电机的容错运行，其单三相控制模式的输出功率能满足整车车上用电器的用电需求，提升双三相BSG电机在故障下BSG混动系统的容错运行能力，缓解BSG电机失效带来的BSG系统失效和整车馈电影响，以保障驾驶人员的人身财产安全。
附图说明
图1是双三相的BSG电机拓扑图。
具体实施方式
以下通过具体实施例进一步说明本发明。
实施例1
一种双三相BSG电机容错运行方法，双三相BSG电机1如图1所示：双三相BSG电机1包括第一三相绕组11和第二三相绕组12，外接的直流电源2通过第一逆变装置31中的六个功率器件即第一一MOS管311、第一二MOS管312、第一三MOS管313、第一四MOS管314、第一五MOS管315和第一六MOS管316转换成三相交流电后分别输入第一三相绕组11的A相、B相和C相，外接的直流电源2通过第二逆变装置32中的六个功率器件即第二一MOS管321、第二二MOS管322、第二三MOS管323、第二四MOS管324、第二五MOS管325和第二六MOS管326转换成三相交流电后分别输入第二三相绕组12的U相、V相和W相，
其中：第一一MOS管311、第一二MOS管312和第一三MOS管313这三者的D极都通过导线连接直流电源2的正极；第一一MOS管311的S极通过导线连接第一四MOS管314的D极并通过导线连接第一三相绕组11的A相，第一二MOS管312的S极通过导线连接第一五MOS管315的D极并通过导线连接第一三相绕组11的B相，第一三MOS管313的S极通过导线连接第一六MOS管316的D极并通过导线连接第一三相绕组11的C相；第一四MOS管314、第一五MOS管315和第一六MOS管316这三者的S极都通过导线连接直流电源2的负极；
第二一MOS管321、第二二MOS管322和第二三MOS管323这三者的D极都通过导线连接直流电源2的正极；第二一MOS管321的S极通过导线连接第二四MOS管324的D极并通过导线连接第二三相绕组12的U相，第二二MOS管322的S极通过导线连接第二五MOS管325的D极并通过导线连接第二三相绕组12的W相，第二三MOS管323的S极通过导线连接第二六MOS管326的D极并通过导线连接第二三相绕组12的V相；第二四MOS管324、第二五MOS管325和第二六MOS管326这三者的S极都通过导线连接直流电源2的负极；
正常情况下，
第一一MOS管311、第一二MOS管312、第一三MOS管313、第一四MOS管314、第一五MOS管315、第一六MOS管316、第二一MOS管321、第二二MOS管322、第二三MOS管323、第二四MOS管324、第二五MOS管325和第二六MOS管326都正常有序工作，保证第一三相绕组11和第二三相绕组12共同输出扭矩实现双三相BSG电机1的轻混功能。
容错运行方法按如下步骤依次实施：
① 识别：当双三相BSG电机1的控制器的故障监控系统识别到第一逆变装置31中的六个功率器件即第一一MOS管311、第一二MOS管312、第一三MOS管313、第一四MOS管314、第一五MOS管315和第一六MOS管316中的任意一个功率器件工作异常时，即当故障监控系统识别到双三相BSG电机1中A、B和C这三相中的任意一相有故障发生，且该故障还仅局限于该三相中，并未导致其他部件损坏情况，及时切断第一逆变装置31的输出，只有第二逆变装置32中的六个功率器件即第二一MOS管321、第二二MOS管322、第二三MOS管323、第二四MOS管324、第二五MOS管325和第二六MOS管326继续被电机控制器控制输出，
双三相BSG电机1中的任意一相的故障包括功率器件短路、功率器件断路和电路对地短路中的至少一种；
② 停止混动：双三相BSG电机1的控制器及时停止BSG混动系统的混动功能，并发送该故障信息给BSG混动系统，BSG混动系统的混动功能主要包括助力、能量回收和自动起停；
③ 切换：双三相BSG电机1的控制器切换控制模式，从双三相控制切换为单三相控制，并且限制功率输出，在容错模式下，单三相控制模式的输出功率能满足整车车上用电器的用电需求，提升双三相BSG电机1在故障下BSG混动系统的容错运行能力，缓解双三相BSG电机1失效带来的BSG混动系统失效和整车馈电影响，以保障驾驶人员的人身财产安全，此时双三相BSG电机1只有其正常时约一半的能力，因此双三相BSG电机1需要限制功率输出，其容错模式下其能力等效于一个传统的车用发电机，电动车辆可以继续以传统车形式继续运行，等待维修。
本实施例以第一逆变装置31发生故障为例，实际使用时若第二逆变装置32发生故障，也可参考本实施例以同样的方法予以控制，即切断第二逆变装置32的输出仅控制第一逆变装置31的输出。
