技术领域
本发明涉及机电变速器的控制***。
背景技术
这个部分中的声明仅提供与本发明相关的背景信息，但是可以不构成现有技术。
已公知的动力系机构包括转矩产生装置，所述转矩产生装置包括内燃机和电机，其将转矩通过变速器装置传递到输出元件。一个典型的动力系包括双模式、复合分解的机电变速器，其利用输入元件和输出元件，其中输入元件从原动机功率源，优选内燃机，接收驱动转矩。输出元件可操作地连接到机动车辆的动力传动***以向其传递牵引转矩。电机，可以作为马达或发电机，独立于来自内燃机的输入转矩，为变速器产生转矩输入。电机可以通过车辆的动力传动***将车辆动能转换为电能储存在电能储存装置中。控制***监控来自车辆和操作者的各种输入，提供动力系的操作控制，包括控制变速器运转状态和齿轮换档，控制转矩产生装置，并且调节电能储存装置和电机之间的电能转换以管理包括转矩和转速的变速器的输出。液压控制***已公知地为实现整个动力系的许多功能而提供加压液压油。
混合动力驱动车辆的上述装置的操作要求控制许多转矩齿轮轴或装置，其表现为连接到上面提到的发动机、电机和动力传动***。来自发动机的输入转矩和来自电机或多个电机的输入转矩被应用，从而单独的或协同的提供输出转矩。混合动力驱动***各种前述构件之间的各种控制方案和操作连接是已公知的，为了执行混合动力系***的功能，控制***必须能够从变速器接合和脱离各种构件。已公知的接合和脱离通过采用选择性的操作离合器在变速器内完成。
离合器是本领域的公知装置，用于接合和脱离轴，包括管理轴与轴之间不同的转速和转矩。离合器在各种设计和控制方法中是已公知的。一个已公知类型的是通过分离或连接两个连接表面而操作的机械离合器，连接表面例如离合器从动盘，操作时，应用摩擦转矩彼此连接。一个用于操作这样的机械离合器的控制方法包括应用液压控制***实现通过液压管线传递流体压力来加入或释放两个连接表面之间的夹紧力。这样操作，离合器没有操作在二元方式下，而是有能力具有一定范围的接合状态，从完全脱离到非接合的同步，到接合但是只有极小夹紧力，到具有最大夹紧力的接合。可以应用到离合器的夹紧力确定了离合器在离合器滑移之前能够承受多少反作用转矩。
如上所述的液压控制***，利用充满液压油的管路选择性的致动变速器内的离合器。然而，液压控制***执行混合动力系中的许多其它功能也是公知的。例如，混合动力系内使用的电机产生热量。已公知的实施例利用来自液压控制***的液压油以连续流体形式来冷却电机，执行基本机器冷却功能。另外的已公知的实施例，具有可选择的或温度驱动的主动机器冷却功能对更高的电机温度起作用，在更高温度条件下提供附加的冷却。另外，已公知的实施例利用液压油润滑机械装置，例如轴承。包括某种水平的内部泄露的液压管路也已公知的。
已公知地，液压油在液压控制***内使用泵被加压。泵可以电力驱动或优选为机械驱动。除了第一主液压泵之外，已公知的液压控制***也包括辅助液压泵。内部推进机构以某一速度旋转工作，拖曳回路中的液压油，给液压控制***加压。通过泵或多个泵的液压流体供应受泵的速度，液压管路压力(PLINE)施加的背压，以及液压油的温度(TOIL)影响。
液压控制***内的合压力或净压力PLNE受许多因素的影响。图1示意性的解释了根据本发明的影响典型液压控制***的液压流的因素的模型。作为本领域的技术人员所知道的，质量守恒解释了，在稳态下，进入***的流量必须等于从***流出的流量。其应用到图1，液压油流体通过液压泵被供应至液压控制***。流体通过液压控制***具有的各种功能流出液压控制***。该典型实施例包括以下功能：如上所述，液压油充满离合器机构以提供锁止离合器所需的夹紧力；液压油提供电机和其它组件所需的基本冷却和主动冷却功能；液压油被用来润滑部分变速器；以及液压油通过内部泄露流入液压管路中。PLINE描述了保存在***中的液压油的总负荷：对任何通过***的流体，***内的总压力依赖于***内的流体阻抗。对于给定的流体，***里更高的流体阻抗导致更高的***压力。相反，对于给定的流体，***里更低的流体阻抗导致更低的***压力。应用到图1，PLINE或液压控制***内的压力，依赖于液压控制***的使用而改变。例如，充满预先未充满的变速器离合器从液压控制***消耗大量的液压油。为了短时期吸入大量的液压油，到离合器的孔口具有低阻抗。结果，在离合器充满过程中，在另外的未改变的液压控制***中的PLINE将会减少。相反，对于通过液压控制***提供的给定的功能设置，PLINE基于泵所供应的流体而改变。对于任何给定设置的，与所提供功能相关的流体阻力，来自泵的增加的流体将导致更高的PLINE。
如上所述，已公知的主液压泵由机械供能，作为发动机的寄生装置被驱动。已公知的混合动力系随着发动机的运行或停止进行运行，这依赖于当前混合动力控制策略。在使用机械驱动主泵的动力系中的发动机停止工作的条件下，主泵不可能提供液压流，并且另一种可选方式是，辅助泵必须被用来提供操纵车辆所需的PLINE。在混合动力系中通过发动机运行和停止操作下准确控制PLINE的方法为液压控制***提供有用的控制。
发明内容
一种控制机电变速器中液压控制***的液压管路压力的方法，所述机电变速器适用于选择性地传递机械功率至输出部件，所述方法包括确定来自主液压泵的可用流量，确定来自辅助液压泵的可用流量，确定被液压控制***提供的功能的流量消耗，基于来自主液压泵的流量，来自辅助液压泵的流量，以及流量消耗来确定液压管路压力估算值，确定满足液压控制***执行功能的期望液压管路压力，比较期望液压管路压力和估算的液压管路压力，以及基于期望液压管路压力与估算液压管路压力的比较结果，控制主液压泵和辅助液压泵。

典型的动力系选择地在几个工作范围状态中的一个进行操作，可以描述为包括发动机工作状态(‘ON’)和发动机停止状态(‘OFF’)之一的发动机状态和包括多个固定档和无级变速的操作模式的变速器状态，在下面的表1中进行相关描述。
表1
每个变速器工作范围状态在表中描述并显示了离合器C1 70、C2 62、C3 73和C4 75中的哪个应用于各个工作范围状态中。第一无级变速模式，即EVT模式I或MI仅在为了“固定”第三行星齿轮组28的外部齿轮元件时通过使用离合器C1 70被选择。发动机状态为ON(‘MI_Eng_On’)或OFF(‘MI_Eng_Off’)中之一。第二无级变速模式，即EVT模式II或MII仅在将轴60连接到第三行星齿轮组28的托架时由使用离合器C2 62被选择。发动机状态为ON(‘MII_Eng_On’)或OFF(‘MII_Eng_Off’)中之一。为了描述的目的，当发动机状态为OFF时，发动机输入速度等于0转每分钟(‘RPM’)，即发动机曲轴没有旋转。固定档位运行提供变速器10的输入-输出速度的固定比值，即获得NI/NO。第一固定档位运行(‘FG1’)通过应用离合器C1 70和C4 75来选择。第二固定档位运行(‘FG2’)通过应用离合器C1 70和C2 62来选择。第三固定档位运行(‘FG3’)通过应用离合器C2 62和C4 75来选择。第四固定档位运行(‘FG4’)通过应用离合器C2 62和C3 73来选择。由于行星齿轮24、26和28的减速传动比降低，随着固定档位运行的增加，输入-输出速度的固定比值运行也增加。第一和第二电机56和72的转速分别为NA和NB，依靠于由离合器限定的机构的内部转动，并与输入轴12测量的输入速度成比例。
响应在用户界面13获得的操作者通过加速踏板113和制动踏板112的输入，HCP5和一个或多个其它控制模块确定指令输出转矩TCMD以满足操作者的转矩要求TO-REQ，并在输出元件64执行并传递到动力传动***90。车辆最终加速度被其它因素影响，例如道路载荷、道路等级和车辆重量。基于动力系的各种操作特征为变速器10确定工作范围状态。这包括操作者的转矩要求，如上所述通过加速踏板113和制动踏板112与用户界面13通信。可以基于动力系转矩要求预测工作范围状态，该转矩要求是根据在电能产生模式或转矩产生模式中操作第一和第二电机56和72的指令所生成。工作范围状态能够被最佳算法或程序确定，其确定了基于操作者对功率、电池充电状态和发动机14和第一和第二电机56和72的功率要求的最佳***效率。控制***管理基于执行的最佳程序的结果管理来自发动机14和第一和第二电机56和72的转矩输入，以及因此***效率最优化，以管理燃油经济性和电池充电。此外，可以基于构件或***的错误确定操作。HCP5监控转矩产生装置，并确定来自变速器10的输出，车轮输出转矩要求达到要求的输出转矩以满足操作者的转矩要求。从上面的描述可以看到，ESD74和第一和第二电机56和72是电操作连接的，其间有能量流。此外，发动机14，第一和第二电机56和72，以及机电变速器10是机械操作连接的，在其间传递功率以产生能量流到输出元件64。
图4示出了液压控制回路42的示意图，其在典型变速器中用于控制液压油的流动。主液压泵88由发动机14的输入轴12驱动，而辅助泵110被TPIM19控制以通过阀140向液压控制回路42提供加压流体。辅助泵110优选包括具有适合尺寸和容量的电动泵，其在运行中向液压控制回路42提供充足的加压液压油流体。液压控制回路42选择性地将液压分配给多个装置，包括转矩传递离合器C1 70、C2 62、C3 73和C4 75，第一电机56和第二电机72的主动冷却回路(未示出)以及通过管道142、144(未详细描述)冷却和润滑变速器10的基础冷却回路。如前所述，TCM17致动各种离合器以通过对液压回路流动控制装置的选择性致动以实现一种变速器操作范围状态，液压回路流动控制装置包括可变的压力控制螺线管(‘PCS’)PCS1 108、PCS2 114、PCS3 112、PCS4 116和螺线管控制的流动管理阀，X-阀119和Y-阀121。液压控制回路42分别通过管路122、124、126和128流体连接到压力开关PS1、PS2、PS3和PS4。压力控制螺线管PCS1 108具有通常比较高的控制位置，并且可操作地通过与可控压力调节器107和滑阀109之间的流体作用调节液压回路中流体压力的幅度。可控的压力调节器107和滑阀109与PCS1 108相互作用以在一定的压力范围内控制液压控制回路42中的液压，并且可以为液压控制回路42提供额外的功能。压力控制螺线管PCS3 112具有通常比较高的控制位置，并且流体连接到滑阀113，其在致动的情况下可操作地影响流动。滑阀113通过管路126流体连接到压力开关PS3。压力控制螺线管PCS2 114具有通常比较高的控制位置，并且流体连接到滑阀115，其在致动的情况下可操作地影响流动。滑阀115通过管路124流体连接到压力开关PS2。压力控制螺线管PCS4 116具有通常比较低的控制位置，并且流体连接到滑阀117，其在致动的情况下可操作地影响流动。滑阀117通过管路128流体连接到压力开关PS4。
在典型***中，X-阀119和Y-阀121均相应地包括被螺线管118、120各自控制的流动管理阀，并都具有高(‘1’)和低(‘0’)的控制状态。控制状态涉及每个阀的位置，这些位置控制在液压控制回路42和变速器10的不同装置中的流动。X-阀119基于下文所述的流体输入源可操作地将加压流体导入离合器C3 73和C4 75，以及分别通过液压管路136、138、144和142将加压流体导入第一电机56和第二电机72的定子的冷却***。Y-阀121基于下文所述的流体输入源可操作地分别通过流体管路132和134将加压流体导入离合器C1 70和C2 62。Y-阀121通过管路122流体连接到压力开关PS1。
液压控制回路42包括提供液压流体以对第一电机56和第二电机72的定子进行冷却的基础冷却回路。基础冷却回路包括来自阀140的流体管路，其直接流入通往流道144的节流器和通往流路142的节流器，其中流道144通往第一电机56的定子的基体冷却回路，流路142通往第二电机72的定子的基体冷却回路。第一电机56和第二电机72的定子的主动冷却受到压力控制螺线管PCS2114、PCS3 112和PCS4 116和螺线管控制的流动管理阀X-阀119、Y-阀121的选择性致动的影响，其导致在选择定子周围液压流体的流动，并允许首先通过传导将热量传输。
在下文的表2中给出了在一种变速器工作范围状态下实现对典型液压控制回路42的控制以控制变速器10的运行的典型逻辑表格。
表2
低范围定义成一种变速器工作范围状态，其包括第一无级变速模式和第一第二固定档位操作中的一种。高范围定义成一种工作范围状态，其包括第二无级变速模式和第三第四固定档位操作中的一种。X-阀119和Y-阀121的选择性控制和螺线管PCS2 112、PCS3 114以及PCS4 116的致动使得液压流体到离合器C1 70、C2 63、C3 73和C4 75的流动变得简单，并为第一电机56和第二电机72的定子提供冷却。
在操作中，为典型变速器10选择变速器工作范围状态，即固定档位模式和无级变速模式中的一种，基于动力系的各种运行特性被选择。这包括操作者转矩请求，其如前所述典型地通过到UI 13的输入通讯。此外，基于包括道路坡度、路面状况或风阻在内的外部状况预测输出转矩指令。工作范围状态可通过动力系转矩指令预测，该指令由控制模块指令引起，以在电能产生模式或转矩产生模式下操作电机。工作范围状态可通过最优化算法或程序确定，其可操作地基于操作者转矩请求、电池充电状态、发动机14与第一电机56和第二电机72的能量效率确定最优化的***效率。控制***基于执行的最优化程序的结果管理来自发动机14、第一电机56和第二电机72的输入转矩，并且实现***最优化以改善燃油经济性并管理电池充电。此外，该操作可以基于构件或***的错误确定。
如上所述，液压控制***的目的是提供加压液压油，实现整个混合动力系的许多功能。本领域的技术人员知道，液压控制***的控制，为了通过供应液压油实施的功能操作能够平顺与连续地进行，需要对PLINE的理解。PLINE对于理解满足所需功能的液压控制***的容量很重要。PLINE也对管理用来为液压控制***提供液压流体的泵或泵组的运行很重要。
PLINE描述了液压控制***拥有的满足要求地功能的能力。例如，在离合器控制功能中，PLINE描述了对离合器即时可用的最大夹紧力。如上所述，离合器传递反作用转矩的能力依赖于施加到离合器上的夹紧力。另外，将被了解，PLINE描述了离合器能被多快的填满。在另一个例子里，本领域的技术人员将了解，关于电机冷却，无论是通过电机提供的基础电机冷却功能，或着是选择性的提供的主动机器冷却功能，通过电机热交换机构的液压油的数量以及该功能引起的热交换能力作为PLINE功能而上升。在另一个例子里，液压油能被用来润滑一种装置，例如，轴承。通过固定孔口流到该装置产生的流体，以及满足润滑功能的液压流体产生的能力是PLINE的能力。
由于许多原因，理解被液压控制***提供的许多功能的流体消耗是重要的。如这些例子所述的，结合要求地功能的理解，最小的PLINE或PMIN可以用来描述为给定的环境设置实现所需功能的每种功能的管路压力。影响每种功能PMIN的环境情况可能包括TOIL，描述为该功能提供的液压油的特征，以及描述功能需要的功能专用变量，例如，电机的热损耗率。另外，理解被液压控制***提供的功能的流体消耗，对于理解由如图1所示的，从液压泵进入的流体和提供的功能的流体消耗之间的前述平衡所产生的PLINE也是重要的。
PLINE对于管理用来为液压控制***提供液压流体的泵或泵组的操作是重要的，通过描述施加在泵上的背压描述为对泵的操作的输入，也提供泵或泵组的运行的反馈，提供驱动PLINE与期望的管路压力值的比较。如上所述，每个供应到液压控制***的液压流的泵受施加到泵上的背压的作用。另外，为了提供期望的管路压力的液压泵的准确控制需要某些当前管路压力或PLINE的测量。
基于已公知的泵或泵组的条件和操作，对于泵产生管路压力的能力可以做出不同的估算。例如，最大当前管路压力或PMAX能被定义，描述为如果当前工作泵被控制到其最高流量设置所能产生的最大的PLINE。PMAX能包括激活泵，例如辅助泵，不在当前激活，以及可能包括消耗来自液压控制***的液压流的供应的调节或限制功能。PMAX对提供液压流实现需要高PLINE的值的优先功能是有用的，例如，被需要来快速的充满变速器离合器。
如上所述，PLINE是一个重要术语，对于描述被液压控制***实现的需求，以及在控制泵工作中的需求是有用的。然而，PLINE经常不直接测量。图5示意性的描述了根据本发明能够估算PLINE的典型管路压力估算模块。如上所述，已公知的许多来自液压控制***的液压管路的因素影响PLINE，包括从泵进入液压管路的有效流体，以及各种消耗液压力的装置。模块产生PLINE或PLINEEST的估算值。此外，PLINEEST反馈到该模块，包括在确定PLINEEST中的PLINE引起的背压。按这种方式，影响PLINE的因素能够被建模来产生PLINEEST，用于液压控制***的控制。
图6示意性描述了根据本发明的，能够描述最大可用压力值的典型可用压力估算模块，所述最大可用压力值在当前给定的车辆条件下通过液压控制***产生。在如上所述的对管路压力估算模块的相似操作中，最大可用管路压力估算模块输入描述的各种描述引起的PLINE，以及对估算的最大可用压力或PMAX建模。按此方式，影响PMAX的因素能够被建模来产生PMAX，用于液压控制***的控制。
如上所述，主液压泵已公知为通过发动机机械的供能。混合动力系，充分利用燃油效率操作策略，已公知为随着发动机的运行或停止而操作。在利用机械驱动的主液压泵的动力系中，在发动机停止操作时，主液压泵不可能提供液压流体的供应，另一种可选方式是，一个辅助液压泵必须被用来提供通过液压控制***提供的各种功能运转所需的PLINE。在与发动机运行和停止工作相联系的混合动力系中，一种准确控制PLINE的方法被提供。为了满足通过液压控制***提供的功能需求和解释例如TOIL和PLINE背压的操作特征的需求，通过监测PLINEEST，主液压泵和辅助液压泵的工作能够在发动机运行和发动机停止工作期间被控制。
结合液压控制***提供的功能的理解，对PLINE的理解允许期望管路压力或者PDESIRED的确定。PDESIRED可能包括液压控制***基于PLINEEST的瞬时需要，例如，基于目前应用的填充离合器的过程将引起PLINE下降到PMIN的预测。此外，PDESIRED可能包括期望需求的预测，例如，一种预计的切换，其基于加速踏板位置或来自作为历史驱动方式或数字地图装置这样的源头的有效数据或预期很快需要主动冷却的增加的电机温度。确定PDESIRED的数值、偏差和调整因素可能通过建模或其它足够准确预测液压控制***操作的技术实验的、经验的、预计的确定，以及多种设置PDESIRED的标准可能被同样的发动机用于每个汽缸以及不同的发动机设置、条件或工作范围。许多能够影响PDESIRED选择的因素被预测，以及本发明的目的不是被限定为这里描述的特殊的实施方式。如果没有因素或动机表明PDESIRED被设置于提高的水平，为了减少液压泵的功率需求到最低功率水平，PDESIRED能被设置到PMIN。在对高的PLINE的极大需求被预期，例如，响应加速踏板位置的大的变化，表明瞬时填充离合器以及供应离合器的最大夹紧力的需要，PLINE能被设置到PMAX或简单的被控制到一个最大值。
图7示意性的描述了根据本发明的一个利用PLIINEST控制主泵和辅助泵在被PMIN和PMAX设定的范围内的典型***。泵控制***500包括主泵流量模块505，辅助泵流量模块510，流量最大值计算模块515，有效流量计算模块520，管路压力估算模块525，PLINE最大值确定模块530，PLINE最小值确定模块535，泵控制模块540，以及辅助泵550。主泵流量模块505接收作为输入的NMAIN，主泵的指示速度；主泵控制因素，指示调节由主泵操作导致PLINE的液压流量的任意测量值；TOIL；以及PLINEEST的反馈指示。将会了解，NMAIN能被由主泵直接监测，或在与驱动该泵的发动机转速具有直接驱动比的机械驱动泵的情况下，NMIAN可以通过监测发动机转速和应用该直接驱动比来获取。主泵控制因素可以包括被该***利用来调节主泵输出的任何已公知方式的描述，例如，可选择的限流器的使用，可选择的流体旁路的使用，或用来影响产生的PLINE的电磁线圈的使用。主泵流量模块505利用输入来对FLOW MAIN项建模或对其进行估算，该FLOW MAIN项描述当前来自主泵并对PLINE作出贡献的液压流量。此外，主泵流量模块505估算FLOW MAIN MAX，其描述了当前给定车辆工况下能从主泵传递的最大流量。辅助泵流量模块510接收作为输入的NAUX，辅助泵550的指示速度；TOIL；以及PLINEEST的反馈指示。依赖于液压控制***设置，描述辅助泵控制因素的附加输入能附加地被实现。辅助泵流量模块510利用输入来对FLOW AUX项建模或对其估算，该FLOW AUX项描述来自辅助泵并对PLINE作出贡献的当前液压流量。此外，辅助泵流量模块510估算了FLOW AUX MAX，其描述了当前给定车辆工况下能从辅助泵传递的最大流量。流量最大值计算模块515接收来自前述流量模块的FLOW MAIN MAX和FLOW AUX MAX信号，并提供一个流量最大值项，其描述了当前给定车辆工况下能被主泵和辅助泵提供的最大流量。相似地，有效流量计算模块520接收来自前述流量模块的FLOWMAIN和FLOW AUX信号，并提供一个有效流量项，其描述了被主泵和辅助泵提供的总的当前流量。关于图5，如上所述，管路压力估算模块525可操纵的接收输入并提供PLINEEST，其描述当前估算的PLINE。应该注意，PLINE能通过压力传感器直接测量。PLINE最大值确定模块530利用输入，包括从上述的模块515和525中产生的项，来产生PMAX。PLINE最小值确定模块535利用输入，包括描述必须被液压控制***满足的功能需求所生成的项，来产生PMIN。泵控制模块540接收来自如上所述的模块525，530，和535的输入和PDESIRED。泵控制模块包括到辅助泵550的控制输出。泵控制模块540能描述一个单独装置，其发出控制指令至影响来自主泵流量的装置，例如，流量调节器，以及至辅助泵550和任何影响来自辅助泵550的流量的装置。另一种可选方式是，泵控制模块540能包含的描述多个装置，其提供与泵及其输出的操作与调节有关的指令及控制功能。另一种可选方式是，泵控制模块540能与其它模块通讯，例如，所述压力调节器控制模块560。
虽然上述实施例描述了一个利用被发动机及一个电驱动辅助泵驱动的主泵的***，但本领域的技术人员将会懂得，所述的方法能在广泛种类的液压控制***结构中使用。例如，单一电驱动泵能被用来代替上述的双泵实施例，以及PLINE能被用来控制这样一种结构。
应当理解在本发明的范围内可以进行修正。已经特别参考优选实施例和其变型来对本发明进行了说明。进一步的修正和替换还可以基于阅读和理解说明书来对其它部分进行。其旨在包括所有这些修正和替换，只要其进入本发明的范围内。
