Description

带有超速离合器的功率分流式混合动力传动系统
技术领域
本公开涉及用于混合动力电动车辆的动力传动系统。
背景技术
一类混合动力电动车辆的动力传动系统，通常被称为功率分流式动力传动系统，具有两个动力源。第一动力源包括内燃发动机，而第二动力源包括电动马达、发电机和电池的组合。发动机和发电机连同行星齿轮组、中间轴和马达一起建立流向车辆牵引车轮的机械式扭矩流动路径和机电式扭矩流动路径。电池是用于发电机和马达的能量存储设备。在任何发电机转速和车速，发动机功率被分成两个功率流动路径。发动机转速由发电机控制，这就意味着在容许的发电机转速范围内，发动机转速可与车速脱钩。当发电机使用发动机的机械动力输入产生电力时，这种操作模式被称为“正动力分配”。
由于行星齿轮组的机械性能，发电机可将动力分配给行星齿轮组来驱动车辆。这种操作模式被称为“负动力分配”。因此，发电机、马达和行星齿轮组的组合可被认为具有电无级变速器(e-CVT)的特性。
可激活发电机制动器使得发动机输出功率仅通过机械路径以固定齿轮比传递到动力传动系统的扭矩输出侧。因为没有倒挡齿轮(reverse gear)，所以第一动力源只能影响车辆的向前推进。发动机需要发电机控制或应用发电机制动器来传递用于前向驱动的输出功率。
当第二动力源被激活时，电动马达从电池汲取电力并独立于发动机驱动车辆以进行前向驱动和反向驱动两者。如果发动机产生的功率超过驾驶员需求，或者在捕获车辆动能的再生模式下，马达也可产生功率并给电池充电。此外，发电机能够从电池汲取电力并依靠发动机功率输出轴上的单向离合器的反作用而驱动以沿向前方向推进车辆。这种操作模式被称为“发电机驱动模式”。车辆系统控制器协调这两个动力源，使它们无缝地协同工作以在不超过动力传动系统系统限制的情况下满足驾驶员的扭矩需求。车辆系统控制器允许针对任何给定的车速和功率请求而连续调节发动机转速。机械式动力流动路径通过行星齿轮组为驱动轴提供有效的动力传递。

具体实施方式

现参照图1，示出了具有功率分流式动力传动系统的混合动力电动车辆。动力传动系统包括连接到传动系的两个动力源：(1)经由行星齿轮传动装置20连接在一起的发动机16和电机50(可被称为发电机)；(2)电驱动系统，包括电池12、电机46(可被称为马达)和发电机50。电池12是用于马达46和发电机50的能量存储系统。
车辆系统控制器(VSC)10被配置为将控制信号发送到电池12、发动机16、马达46以及发电机50中的一个或更多个并从它们那里接收感测的反馈信息，以为车辆牵引车轮40提供用于推进车辆的动力。控制器10控制电池12和发动机16之间的功率配比以提供推进车辆的动力，并因此控制电池12的荷电状态(SOC)。
传动装置14包括行星齿轮传动装置20，它包括环形齿轮22、中心齿轮24和齿轮架总成26。环形齿轮22将扭矩分配到包括啮合齿轮元件28、30、32、34和36的阶梯传动比齿轮。传动装置14的扭矩输出轴38通过差速器和车桥机构42可驱动地连接到车轮40。齿轮30、32和34安装在中间轴31上，齿轮32与马达驱动的齿轮44啮合。马达46驱动齿轮44。齿轮44用作中间轴31的扭矩输入。发动机16通过输入轴18将扭矩分配到传动装置14。电池12通过功率流动路径48将电力输送到马达46。如52处所示，发电机50电连接到电池12和马达46。
在发动机16关闭而电池12用作唯一的动力源时，输入轴18和齿轮架总成26由超越联轴器(即，单向离合器(OWC))53制动。当发动机16开启且动力传动系统处于并联驱动模式时，机械制动器55使发电机50的转子和中心齿轮24固定，中心齿轮24用作反作用元件。
控制器10接收来自传动装置挡位选择器的信号PRND(驻车、倒车、空挡、前进)63，该信号连同如71处所示的期望的车轮扭矩、期望的发动机转速和发电机制动命令一起被分配到传动装置控制模块(TCM)67。电池开关73在车辆“点火开关接通”启动后关闭。根据加速器踏板位置传感器(APPS)的输出65，控制器10向发动机16发出期望的发动机扭矩请求，如69处所示。如61处所示，制动踏板位置传感器(BPPS)将车轮制动信号分配到控制器10。制动系统控制模块(未示出)可基于来自BPPS的信息向控制器10发出再生制动命令。TCM 67向发电机制动器55发出发电机制动控制信号。TCM 67还将发电机控制信号分配到发电机50。
现参照图2，示出了图1的动力传动系统的各个组件之间的功率流动路径的框图。在驾驶员使用发动机节气门的控制下，燃料被输送到发动机16。发动机16将发动机功率(τeωe，其中τe是发动机扭矩，ωe为发动机转速)输送到行星齿轮传动装置20。行星齿轮传动装置20将功率(τrωr，其中τr是环形齿轮扭矩，ωr是环形齿轮转速)输送到中间轴31。输出轴38将功率(Pout＝τsωs，其中τs和ωs分别是输出轴38的扭矩和转速)输出到车轮40。发电机50可将功率输送到行星齿轮传动装置20或者可由行星齿轮传动装置20驱动。类似地，马达46和中间轴31之间的功率分配可沿任一方向进行。来自电池12的驱动功率或电池12的充电功率由双向箭头48表示。
发动机输出功率(τeωe)可分成机械功率流动路径(τrωr)和电功率流动路径(τgωg到τmωm，其中τg是发电机扭矩，ωg是发电机转速，τm是马达扭矩，ωm是马达转速)。在这种所谓的正分配操作模式下，发动机16将功率输送到行星齿轮传动装置20，行星齿轮传动装置20将功率(τrωr)输送到中间轴31，中间轴31进而驱动车轮40。行星齿轮传动功率中的一部分(τgωg)被分配给发电机50，发电机50将充电功率输送到电池12。电池12驱动马达46，马达46将功率(τmωm)分配到中间轴31。
如果发电机制动器55被激活，则建立并联操作模式。在并联操作构造中，发动机16开启而发电机50被制动。电池12为马达46提供电力，马达46在动力从发动机16传递到行星齿轮传动装置20再传递到中间轴31的同时为中间轴31提供动力。在利用第二动力源(被描述为包括电池12、马达46和发电机50)的操作期间，马达46从电池12汲取电力并独立于发动机16向动力传动系提供推进。
如上所述，HEV具有两个动力源，用以将驱动功率输送到车轮40。第一动力源包括发动机16，第二动力源包括电池12。发动机16和电池12可同时或独立地提供牵引功率。控制器10控制电能和燃料能的配比以满足推进要求，从而相应地控制发动机16和电池12。
如可以观察到的，行星齿轮传动装置20在发动机16、发电机50和车辆牵引车轮40之间施加转速和扭矩关系。如上所讨论的，发电机50可被控制为使用行星齿轮传动装置20作为CVT而将动力从发动机16传递到车辆牵引车轮40。然而，在一些工况下，运转发电机50引起的损失超过CVT的能量效益。
作为示例，当车辆处于“稳态”操作(诸如以大致恒定的速度巡航)时，发电机50引起的运转损失可能超过1千瓦，而发动机16和牵引车轮40之间的齿轮比大致保持不变。这里，稳态操作是指车速恒定、驾驶员功率请求恒定以及用于给车辆充电的发动机功率的量大体上一致。这通常发生在驾驶员功率需求与“道路负载”或作用于车辆的力(例如滚动阻力、空气动力阻力等)的总和大致相同时。
现参照图3，示出了根据本公开的动力传动系统。该动力传动系统包括连接到传动系的两个动力源：(1)经由行星齿轮传动装置20'连接在一起的发动机16'和发电机50'；(2)电驱动系统，包括电池12'、电动马达46'和发电机50'。行星齿轮传动装置20'连同啮合齿轮元件28'、30'、32'、34'和36'限定发动机16'、发电机50'和牵引车轮40'之间的第一机械联动装置。啮合齿轮元件30'、32'和34'围绕共同的输出轴79旋转，啮合齿轮元件34'和36'在输出轴79和牵引车轮40'之间限定主减速比。
另外，该动力传动系统包括固定地结合到齿轮元件30'而与输出轴79共同旋转的并联超速轴80。超速轴80结合到齿轮元件82，齿轮元件82与齿轮元件84啮合旋转。离合器86可操作为选择性地将齿轮元件84结合到发动机16'。在优选的实施例中，离合器86是牙嵌式离合器或电子控制的液压摇臂单向离合器。当离合器86接合时，啮合齿轮元件84和82具有被配置为在发动机16'和输出轴79之间限定超速转速和扭矩关系的固定齿轮比。如将在下面参照图4A和图4B所讨论的，控制器88被配置为响应于各种工况而选择性地命令离合器86接合或分离。当然，可以使用在发动机16'和输出轴79之间施加超速转速关系的其他齿轮传动装置。
现参照图4A和图4B，以流程图的形式示出了控制动力传动系统的操作的方法。如在块90处所示，在离合器分离的情况下，根据正常逻辑(nominal logic)操作混合动力车辆的动力传动系统。然后确定是否满足第一工况，如在操作92处所示。第一工况通常对应于从非稳态操作变为稳态操作，或对应于驾驶员功率需求和道路负载之间的差的大小降低。第一工况可以是在块94处示出的列表A中的工况之一。第一工况可以是在第一稳定加速事件中的大致恒定的驾驶员功率需求。第一工况也可为：在第二加速事件之后，功率需求降低到大致等于道路负载。第一工况也可以是：在第三加速事件之后，驾驶员功率需求降低和再生制动的激活。应当注意的是，关于所述加速事件，“第一”、“第二”和“第三”是为了清楚起见而使用的，并非表示任何顺序或要求同时发生。如果不满足第一工况，则控制返回到块90。如果满足第一工况，那么使离合器接合并以超速模式控制动力传动系统，如块96处所示。
然后确定是否满足第二工况，如在操作98处所示。第二工况通常对应于稳态操作的继续，或对应于驾驶员功率需求和道路负载之间的差大致恒定。第二工况可以是在块100处示出的列表B中的工况之一。第二工况可包括车速或驾驶员功率需求的小的偏差。在一些实施例中，可设置速度偏差阈值或者功率需求偏差阈值。在这样的实施例中，速度偏差或功率需求偏差不超过各自的阈值可满足第二工况。第二工况也可以是在车辆充电模式改变的情况下大致恒定的驾驶员功率需求。在一些转速和扭矩范围内使用马达充电更有效，而在其他范围内使用发电机充电更有效。从马达充电切换到发电机充电或从发电机充电切换到马达充电连同大致恒定的驾驶员功率需求将因此满足第二工况。类似地，从“不充电”模式变为充电模式连同大致恒定的驾驶员功率需求将因此满足第二工况。如果确定满足第二工况，则如在块102处所示，离合器保持在接合位置。随后控制返回到操作98。因此以超速模式控制动力传动系统同时稳态操作继续。
如果确定不满足第二工况，则如在块104处所示，确定是否满足第三工况。第三工况通常对应于从稳态操作变为非稳态操作，或对应于驾驶员功率需求和道路负载之间的差的大小增加。第三工况可以是在块106处所示的列表C中的工况之一。第三工况可以是功率需求的大幅降低或功率需求的大幅增加。在一些实施例中，设置功率需求偏差阈值，且如果驾驶员功率需求偏差超过阈值则满足第三工况。这可包括针对功率需求降低的第一阈值和针对功率需求增加的第二阈值。第三工况也可以是车辆制动器的重度应用。在一些实施例中，设置制动阈值，且如果驾驶员制动应用超过阈值则满足第三工况。第三工况也可以是车速的大幅降低。在一些实施例中，设置速度偏差阈值，如果车速的降低超过阈值则满足第三工况。第三工况可以是发动机关闭请求。如果电池的荷电状态足以支持电动操作，并且发出发动机关闭请求，则满足第三工况。如果确定不满足第三工况，则控制行进到块102。如果满足第三工况，则如在块108处所示，使离合器分离。然后控制返回到块90。
现参照图5和图6，示意性地示出了可与本公开一起使用的电磁单向离合器110。单向离合器110包括具有凹口(pocket)114的摇臂板112，每个凹口114容纳相应的摇臂116，摇臂116可枢转地铰接于相应的凹口114内。离合器110还包括凸轮板118，凸轮板118具有限定齿的多个缺口120。当摇臂116相对于凹口114枢转时，齿可以卡住摇臂116的向内延伸部。摇臂116通过弹簧121被偏置以保持在凹口内而不伸出。在该配置中，摇臂116和缺口120之间没有接合，因此在摇臂板112和凸轮板118之间不传递扭矩。图5示出了处于该分离位置的离合器110。
凸轮板118包含线圈(未示出)，线圈可选择性地通电以产生磁力并使离合器110接合。响应于该磁力，摇臂116抵抗弹簧121的偏置力而从凹口114向外枢转，使得摇臂116的一部分伸出超过摇臂板112的径向内面。摇臂116的伸出部可与缺口120接合，并沿一个旋转方向在摇臂板112和凸轮板118之间传递扭矩。图6示出了处于该接合位置的离合器110。
现参照图7A和图7B，示出了使离合器接合的方法，该方法可连同本公开一起使用。图7A示出了使单向离合器接合的方法。如在块122处所示，控制发电机以使离合器超越。这可通过沿分离方向旋转摇臂板来执行。然后离合器被激活，如在块124处所示。如上面关于图6所讨论的，这可包括响应于摇臂枢转并接合凸轮板中的缺口，使线圈通电以产生磁场。然后离合器接合，如在块126处所示。这通过沿接合方向旋转摇臂板短距离以使摇臂与凸轮板中的齿接合而执行。然后发电机承载的扭矩被传递到离合器，如在块128处所示。
图7B示出了接合牙嵌式离合器的方法。如在块130处所示，发电机转速被控制为与离合器同步的目标转速。然后离合器接合，如在块132处所示。然后发电机承载的扭矩被传递到离合器，如在块134处所示。
现参照图8A和图8B，示出了使离合器分离的方法，该方法可连同本公开一起使用。图8A示出了使单向离合器分离的方法。如在块136处所示，离合器承载的扭矩被传递到发电机。如在块138处所示，控制发电机以使离合器超越。这可通过沿分离方向旋转发电机来执行。然后停用离合器，如在块140处所示。然后发电机控制恢复到正常操作，如在块142处所示。
图8B示出了使牙嵌式离合器分离的方法。如在块144处所示，离合器承载的扭矩被传递到发电机。然后离合器分离，如在块146处所示。然后发电机控制恢复到正常操作，如在块148处所示。
虽然以上描述了示例性实施例，但并不意味着这些实施例描述了本发明的所有可能的形式。更确切地，在说明书中使用的词语是描述性词语而不是限制性词语，应理解的是，在不脱离本发明的精神和范围的情况下，可进行各种改变。此外，可将各个实施的实施例的特征进行组合以形成本发明的进一步的实施例。
