Abstract

本发明提出了一种高电压联锁回路(HVIL)***和控制策略，其用于替代燃料车辆，如电动车辆、混合动力电动车辆、或者燃料电池车辆。总体上，提出了具有包括HVIL电路的相关逻辑电路的HVIL***，以基于HVIL***的运转状态而允许车辆在由电源供电的高电压(HV)或供电模式下或HVIL中断模式下运转。当HVIL电路出现高短路、低短路、或开路时，设置诊断故障码(DTC)并亮起立刻维修指示灯以指示维修技术员在维修HV***时需要额外注意安全防范。当不希望HV出现在连接器与HV装置时，可以启动或者可以不启动HV接触器向车辆提供HV。

Description

高电压联锁***和控制策略
技术领域
本发明总体上涉及一种高电压联锁，更具体地，涉及一种具有监控***的高电压联锁。 
背景技术
现代的车辆通常包括许多高电压电气装置。高电压装置会面临在传统的低电压***中没有遇到的挑战。如果发生车辆事故或车辆部件故障，短路的高电压***会由于相对的高电压电平而持续造成严重损害。另一个担心是不希望车辆使用者或其他人直接或间接地接触到高电压电平。 
现有的高电压联锁确实为预期会接触高电压电气***的使用者(诸如维护人员)提供了一定程度的安全性，但是不能够在使用者不经意间接触高电压电力***的情况下提供保护。 
尽管现有的装置适合于它们的预期目的，但所需要的是一种允许监控与线路故障有关的高电压联锁回路(High Voltage Interlock Loop，简称HVIL)的***。这允许在维修高电压***之前提醒线路故障***的维修人员需要额外防范。 
发明内容
本发明提供了一种高电压联锁回路(HVIL)***和控制策略，其用于替代燃料车辆，例如，电动车辆、混合动力电动车辆(hybrid electric vehicle)、或者燃料电池车辆。总体上，提供了具有包括 HVIL电路的相关联逻辑电路的HVIL***，以允许车辆基于HVIL***的运转状态而在由电源供电的供电模式或高电压(HV)模式、或HVIL中断模式下运转。 
附图说明
本发明的这些目标或其他目标、特征与优点将从以下的详细描述与附图中变得显而易见，在附图中： 
图1示出了根据本发明一个实施例的HVIL监控器和控制策略。 
图2示出了根据本发明一个实施例的监控策略的表格。 
图3示出了根据本发明一个实施例的HVIL控制策略。 
具体实施方式
图1示出了一种示例性的燃料电池车辆，并且包括根据本发明一个实施例的HVIL控制***10和策略。然而，在不背离本发明范围的情况下，本发明可以与任意的混合动力电气***一起使用，这些混合动力电气***包括由内燃机驱动的车辆、串联式混合动力电动车辆(series hybrid electric vehicle，简称SHEV)、并联式混合动力电动车辆(parallel hybrid electric vehicle，简称PHEV)、以及与车辆电池结合来使用高电压电源的电动车辆。图1示出了根据本发明一个实施例的HVIL控制***的电路图。 
示例性的燃料电池车辆10包括电气运转或控制的部件，这些部件包括燃料电池154、变速器16、及车辆电池220。这些部件与变速器内的行星齿轮组24、IPT 72内的逆变器28、电动机/发电机26一起运转，以驱动半轴38(位于变速器的输出端)与车轮40。集成动力系驱动桥(Integrated Powertrain Transaxle，简称IPT)72控制 并监控发动机14和电动机/发电机26的扭力输出量。如图1中所示出的与进一步详细论述的，燃料电池154、变速器16、及车辆***控制器(VSC)78配合来形成用于车辆10的***。 
车辆***控制器(VSC)78控制车辆运转的所有方面。VSC 78监控车辆运转并控制车辆10。VSC 78生成信号并将信号传送至车辆部件。这些部件按照VSC 78的指示运转。VSC 78可以独立地和共同地控制各个部件以控制车辆运转。 
在本发明的一个实施例中，车辆10包括HVIL监控器与控制器模块微处理器86。HVIL监控器与控制器模块微处理器86通过惯性开关192、多个HV附件连接器(accessory connector)193、及HV继电式接触器194向一个或多个HV接触器182、184提供HVIL控制逻辑。 
在图1中所示的本发明的实施例中，HVIL控制***10包括两个HV接触器182、184。在本发明的其他实施例中，可以包括一个或多个HV接触器。 
如图1中所示，在本发明的一个实施例中，控制器模块86与相关联的控制逻辑电路可以设在VSC 78内。 
在本发明的一个实施例中，HVIL模块86可以与VSC 78运转地通信，但可以设在与VSC 78相分离的位置。 
在本发明的实施例中，VSC 78包括相关联的HVIL启动开关80，HVIL启动开关80与VSC 78进行信号通信并用于选择性地使车辆电池220与VSC 78耦合或退耦。高电压联锁***逻辑电路与车辆***控制器(VSC)进行电通信并可以集成为VSC内的子模块。 
将来自HVIL 212源信号的信号输入到惯性开关192中。当惯性开关192关闭(close)或未触发时，HVIL源212成为连接至配电箱206和与其相关联的部件的HVIL输出214。当监控到HVIL源212和HVIL读出信号204中断时，则HVIL输出214被输入至HV连接器193并成为HVIL读出信号204。当惯性开关192关闭时以及当HV连接器193与启动的HV继电式接触器194对接时，HVIL源212与HVIL读出信号204为相同的信号，如此配合来形成将车辆电池220的电能提供至HV接触器182、184的HVIL电路224。基于HVIL电路的运转，VSC 78能够控制车辆10内所感应和分配的电能的运转。 
图1示出了示例性的燃料电池车辆10。燃料电池车辆包括类似于下面描述的与具有内燃机的车辆相关的那些部件的部件。 
图1中所示的燃料电池车辆10包括燃料电池154和牵引电动机/发电机26。燃料电池154取代传统的发动机，但是类似地由VSC78来控制该燃料电池。由逆变器28与齿轮24所驱动的牵引电动机/发电机26由VSC 78来控制。逆变器28与牵引电动机/发电机26依靠高电压母线160提供的电能来运转。高电压母线160接收来自燃料电池154的电能。直流/直流转换器162接收来自HV电能母线160的电能输入，并供应12V至车辆低电压电气***且对12V的电池220再充电。燃料电池154进一步包括空气调节压缩机68与相关联的控制器70、空气模块66、以及HV水泵52。 
图1示出了根据本发明一个实施例的用在具有HVIL模块86的车辆中的高电压联锁控制***10和策略。 
HVIL控制***10包括与多条信号线进行信号通信的VSC 78，这些信号线包括：HVIL源线(source line)212，当惯性开关192关闭时HVIL源线从VSC 78引出到HVIL输出线214；以及惯性读 出线216，当惯性开关192断开(trip)时惯性读出线进一步与能量管理模块(EMM)23进行通信；以及HVIL读出线204，其进一步与HV接触器控制器继电器(contactors controller relay)194、配电箱(PDB)206进行信号通信，并且使用CAN网络协议218进一步与IPT接口202、扭力控制器222和其他车辆***进行运转地通信。 
VSC 78提供用于HVIL电路224的源，并运转以控制HVIL***以及监控非一致性的HVIL运转状况。 
在本发明的实施例中，HVIL电路224进一步地与监控高电压电池读数的能量管理模块23进行运转地通信，其中，为使HV电源154向与PDB 206进行信号通信的模块供电，HVIL读出线204的输入必须高且惯性读出线216必须低。 
在本发明的另一实施例中，如果VSC 78使用来自车辆电池220的电能，则VSC 78可以不必监控用于HV电池就绪的HVIL电路224，其中，EMM 23读取惯性读出线216的输入。 
PDB 206经由与包括空气模块66、A/C压缩机68、以及HV水泵54的多个模块进行通信218的HV母线160来控制VSC 78、IPT接口202、辅助电池220、以及电源154之间的通信。 
HVIL控制***10的运转依赖HV接触器控制器194，在图1中显示为作为开关运行的继电器，在图1中显示为未启动，鉴于HV接触器182、184没有触发或打开，从而阻止电能从HV母线160到所选择的车辆***或部件。当由HVIL读出电路204启动HV接触器控制器继电器194时，HV接触器182、184在正常车辆运转模式下关闭，随后当HV接触器182、184被触发或关闭时，如本文所公开以及如图1所示，HV电源154为所选择的车辆部件54、66、 68供电。如图1所示，HV接触器182、184是作为单刀单掷开关来运转的常开继电器(normally open relay)。 
对于与VSC 78和EMM 23的通信采用了惯性开关192。当惯性事件发生时，惯性开关192断开，从而在HVIL源线212与惯性读出线216之间形成连接。惯性开关192运转在与HV控制器194的开关状态相反的开关状态，当惯性开关192断开时，惯性读出线216将第二数字输入164传送到EMM 23中，其中，第二数字输入164具有相关联的第二下拉电阻器176，该第二下拉电阻器被引入到EMM 23并且根据HVIL电路224的运转模式(具体地，惯性读出线216的运转状态)在高状态或低/开状态之间切换。 
在图1中所示的本发明实施例中，IPT 72包括相关联的IPT微处理器202，该IPT微处理器202与VSC 78进行信号通信。 
第一数字输入160具有相关联的引入到VSC 78与EMM 23的下拉电阻器174，并连接至HVIL读出线204，其根据HVIL电路224的运转模式(具体地，HVIL惯性读出线204的状态)在高状态或低/开状态之间切换。 
HVIL电路224根据接收到的来自VSC 78的命令来为HV接触器182、184供电。 
HVIL电路224包括：HVIL源线212，其由VSC 78控制导通并为HV接触器182、184供电直至HV接触器开路事件(open event)发生时关闭；HVIL读出线204，如果惯性读出开关192没有断开或者由于HVIL读出电路204没有断路(broken)而关闭，则HVIL读出线与HVIL源线212处于相同的电势；惯性读出线216，如果惯性读出开关192断开或关闭，则惯性读出线与从VSC 78引出的HVIL源线212处于相同的电势。VSC 78与用于车辆通信的CAN ***218进行信号通信并提供用于HVIL控制***10的协议检查。HVIL电路224包括：作为从VSC 78到多个HVIL相关模块的引出线的HVIL源线212，这些相关模块包括空气模块66、A/C压缩机68、相关联的A/C压缩机控制器70、及HV水泵52；以及作为从多个HVIL相关模块到VSC 78和HV接触器控制器继电器194两者的引出线的HVIL读出线204。 
如果惯性开关192没有断开，则HVIL输出线214与HVIL源线212处于相同的电势，然而，HVIL输出线214不被HVIL控制***10监控。 
图3示出了基于特定的车辆运转模式使用HVIL控制***10来执行多种选项的HVIL控制策略与方法230的流程图。 
最初，在启动HVIL启动开关80之前，由VSC 78与控制器模块微处理器86来监控HVIL源212(231)，用于判断它是否为12V短路(232)。如果HVIL源212为低(233)，则假定HVIL源没有高短路(shorted high)(234)并准备启动。如果HVIL源212为高(235)，则假定HVIL源212短路并设置DTC。随后启动HVIL启动开关80(236)，车辆能够运转。 
在本发明的实施例中，随后监控HVIL读出线204(237)。如果HVIL读出线204的输入为低(239)，则HVIL源212和/或HVIL读出线204为开路或低短路(shorted low)，其中，也设置DTC(240)。如果HVIL读出线204的输入为高(238)，则***良好并且不需要做出动作(241)。 
在本发明的实施例中，当VSC 78从HVIL读出线204读出低输入时，则四个事件中的一个事件已经发生，指示选自以下事件中的一个事件：HVIL开路、本地开路、惯性开关断开、或接地短路。 
如果检测到HVIL开路，则HV接触器182、184处于打开状态，从而禁止HV母线160和燃料电池154连接。VSC 78从CAN 218确认HV运转状态。 
如果检测到本地开路，则存在HV接触器182、184可以能处于打开状态或关闭状态以及HV母线160的电势为高。 
VSC 78从CAN 218检查HVIL电路224的运转状态。此外，可以从CAN检查车辆内的其他模块的状态，该CAN包括但不限于HVIL读出线204和惯性读出线216。 
在本发明的另一实施例中，EMM 23读取来自惯性开关192的输入，并确定惯性开关是否处于断开状态或关闭状态。 
在本发明的另一实施例中，当车辆行驶时，VSC 78确定HVIL电路224的HVIL源线212是否存在接地短路。如果存在接地短路，则与HV接触器控制器194相关联的保险丝48会熔断，从而HV接触器182、184处于打开状态，从而将12V电池220与HVIL电路224退耦。 
HVIL读出信号204是从HVIL读出线204或间接地从HVIL电路224输入至VSC 78中的高输入或低输入的逻辑信号，其中，HVIL读出信号204向HV继电式接触器194提供控制，HV继电式接触器194为HV接触器182、184供电。当HVIL电路224断路时，辅助电池220将不为HV接触器182、184供电。 
图2示出了指示车辆与特别是HVIL控制***10的运转状态的逻辑表格300。 
图2中所示的逻辑表格示出了在应用HVIL启动开关80之前和之后监控HVIL源212的状态。该表格指示了HVIL源212是否为 12V短路。HVIL启动开关80一启动，则使用与引入到VSC 78的HVIL读出线204相关联的第一数字输入160来监控HVIL读出线204。与HVIL源212有关的HVIL读出线204的电平指示了HVIL电路的可以能故障情况。
