各控制模块内控制和状态估计的算法通常在预定循环期间执行,使得各循环至少执行一次各算法。存储在非易失性存储装置内的算法由中央处理器中的一个执行,其可操作以监测感测装置的输入,并执行控制和诊断程序,以使用预定标准控制各装置的操作。循环通常以规则的间隔进行,例如在正运行的发动机和车辆运行期间,每3.125、6.25、12.5、25和100毫秒执行一次。可选择地,可响应于事件的发生执行该算法。
响应于操作员的动作,如UI 13所捕获的,管理HCP控制模块5及其它控制模块中的一个或多个确定轴64的操作员扭矩需求。适当地控制和操作变速器10的有选择性操作组件,以响应于操作员需求。例如,在图1和2所示的典型实施例中,当操作员选择前进档范围,并且操作加速踏板或制动踏板时,HCP 5确定输出扭矩,这影响了怎样以及何时车辆加速或减速。最终的车辆加速受其它因素影响,包括,如道路载荷、道路坡度和车辆重量。HCP 5监测扭矩发生装置的参数状态,并确定获得操作员扭矩需求所需的变速器输出。在HCP 5的指令下,变速器10在从低至高的输出速度范围内操作,以满足操作员需求。
典型的双模式复合分配机电变速器以下面参考图1和表1描述的几个固定传动操作模式和连续可变操作模式操作。
表1
变速器操作模式 | 致动的离合器 | |
模式I | C1 70 | |
固定速比(GR1)固定速比(GR2) | C1 70C1 70 | C4 75C2 62 |
模式II | C2 62 | |
固定速比(GR3)固定速比(GR4) | C2 62C2 62 | C4 75C3 73 |
表格中所示的各种变速器操作模式表示对于各操作模式,离合器C1、C2、C3和C4中具体哪个接合或致动。另外,在各种变速器操作模式中,MG-A和MG-B可各自操作为产生运动扭矩的电动机,或产生电能的发电机。当为了将第三行星齿轮组28的外齿轮元件“接地”而致动离合器C1 70时,选择第一模式或齿轮系。当松开离合器C1 70,同时致动离合器C2 62以将轴60连接到第三行星齿轮组28的行星架时,选择第二模式或齿轮系。当电机56、72操作为电动机和发电机时,影响了本发明范围外的其它因素,这里不再描述。
图2中主要示出的控制***可操作,以在各操作模式内,在轴64提供多较慢至较快的变速器输出速度范围。在各模式中具有慢至快输出速度范围的双模式组合允许变速器10将车轮从稳定状态推进为调整,并且如上所述地满足各种其它需求。另外,控制***与变速器10联合操作,以允许各模式之间的同步转换。
第一和第二连接可变操作模式指的是变速器功能由一个离合器(即,或者离合器C1 62,或者离合器C2 70)及电机56与72的受控速度和扭矩控制的情形,其可称为连续可变传动模式。下面描述通过应用另外的离合器获得固定速比的特定操作范围。该另外的离合器可为离合器C3 73或C4 75,如上面表格中所述。
当应用另外的离合器时,获得变速器输入对输出速度的固定比,即,NI/NO。电机MG-A 56和MG-B 72的旋转依赖于由离合器限定的机构的内部旋转,与在轴12检测的输入速度成比例。电机MG-A和MG-B用作电动机或发电机。它们完全独立于发动机来输出动力流,从而能够一起用作电动机、一起用作发电机、或者其任意组合。例如,这允许在固定速比1的操作期间,在轴64处从变速器输出的运动动力通过接收ESD 74的动力的行星齿轮组28,由发动机的动力和MG-A与MG-B的动力提供。
参考图3,示出了更加详细描述用于控制典型变速器内液压流体流动的典型电动液压***的示意图。由发动机10驱动输入轴的主液压泵88和由TPIM 19可操作地电控制的辅助泵110通过阀140向液压回路42提供增压流体。辅助泵110优选包括大小及容量适于在操作时向液压***提供充足增压液压流体的电动泵。增压液压流体流入电动控制回路42,该回路可操作,以将液压压力有选择地分配到一系列装置,包括:扭矩传递离合器C1 70、C2 62、C3 73和C4 75,机械A和B的主动冷却回路,通过通路142、144(未详细示出)冷却和润滑变速器10的基本冷却回路。如前所述,TCM 17优选可操作,以致动各种离合器来通过液压回路流动控制装置(包括可变压力控制螺线管(‘PCS’)PCS1 108、PCS2 112、PCS3 114、PCS4 116及电磁控制流量管理阀X-阀118和Y-阀120)的选择性致动获得各种变速器操作模式。该回路通过通路124、122、126和128分别流体连接到压力开关PS1、PS2、PS3和PS4。压力控制螺线管PCS1 108具有常高的控制位置,并且可操作,以通过与可控压力调节器109的相互作用来调节液压回路内的流体压力大小。未详细示出的可控压力调节器109与PCS1 108相互作用,以便依赖于下述操作条件在一定压力范围内调节液压回路42内的液压压力。压力控制螺线管PCS2 112具有常低的控制位置,并且流体地连接到滑阀(spool valve)113,其可操作以便在致动时影响从其通过的流量。滑阀113通过通路126流体连接到压力开关PS3。压力控制螺线管PCS3 114具有常低的控制位置,并且流体地连接到滑阀115,其可操作以便在致动时影响从其通过的流量。滑阀115通过通路124流体地连接到压力开关PS1。压力控制螺线管PCS4116具有常低的控制位置,并且流体地连接到滑阀117,其可操作以便在致动时影响从其通过的流量。滑阀117通过通路128流体地连接到压力开关PS4。
在典型***中,X-阀119和Y-阀121各包括分别由电磁线圈118、120控制的流量控制阀,并具有高(‘1’)和低(‘0’)的控制状态。控制状态指的是各阀控制流向液压回路42和变速器10内不同装置的位置。X-阀119可操作,以依赖于流体输入源,分别通过流体通路136、138、144、142将增压流体引导至离合器C3和C4以及用于MG-A和MG-B的定子的冷却***,如下所述。Y-阀121可操作,以依赖于流体输入源,分别通过流体通路132和134将增压流体至离合器C1和C2,如下所述。Y-阀121通过通路122流体地连接到压力开关PS2。在共同拥有的美国专利申请No.11/263216、代理卷号No.GP 306089、题为“A MultiplexedPressure Switch System for an Electrically Variable Hybrid Transmission”中提供了对典型电动液压控制回路42更加详细的描述,这里通过参考将其并入本文。
液压回路包括用于提供液压流体来冷却MG-A 56和MG-B 72的定子的基本冷却回路。基本冷却回路包括从阀140直接流向限流器146和148的流体管道,其中限流器146通往流体通路144,而流体通路144通往用于MG-A 56的定子的基本冷却回路,限流器148通往流体通路142,而流体通路142通往用于MG-B 72的定子的基本冷却回路。用于MG-A56和MG-B 72的定子的主动冷却由压力控制螺线管PCS2 112、PCS3114和PCS4 116以及电磁控制流量管理阀X-阀118和Y-阀120来实施,这使得液压流体绕着所选的定子流动,并允许热量在其间主要通过传导的方式传递。
下面参考表2,提供实现典型电动液压控制回路42的控制的典型逻辑表。
表2
操作状态 | X-阀逻辑未闭锁 | Y-阀逻辑C2闭锁 | PCS1常高 | PCS2常高 | PCS3常高 | PCS4常低 |
EVT模式I | 0 | 0 | 线路调节 | MG-B定子冷却 | C1 | MG-A定子冷却 |

低范围高范围 | 11 | 01 | 线路调节线路调节 | C2C2 | C1C3 | C4C4 |
X和Y阀的选择性控制以及电磁阀PCS2、PCS3和PCS4的致动利于液压流体致动离合器C1、C2、C3和C4的流动,并给MG-A和MG-B的定子提供了冷却。
在操作中,对于典型的变速器,基于动力系的多种操作特征确定操作模式,即,固定速比和连续可变模式操作之一。这包括操作员对扭矩的需求,如上所述,其通常通过对UI 13的输入来通信。另外,对于输出扭矩的需求以外部条件为基础,包括,如道路坡度、道路表面条件或风力载荷。操作模式可以控制模块指令引起的动力系扭矩需求为基础,来将电机操作于电能产生模式或扭矩产生模式。操作模式可由最优化算法或程序确定,该最优化算法或程序可操作,以便基于操作员对动力的需求、电池充电状态、发动机14及MG-A 56和MG-B 72的能量效率来确定最优的***效率。该控制***基于执行的最优化程序的结果来管理发动机14及MG-A 56和MG-B 72的扭矩输入,***最优化优化了***效率,以提高燃料经济性和管理电池充电。另外,可基于组件或***内的故障来确定操作。
现在参考对照图1、2和3及表1和2描述的变速器,这里描述变速器和控制***的具体方面。该控制***可操作,以基于对扭矩的需求、故障的存在、和电动机的温度来有选择地致动压力控制装置和流量管理阀。该控制***还基于X-阀118和Y-阀120流量管理阀的选择性致动,有选择地控制低范围连续可变操作、高范围连续可变操作、低范围状态和高范围状态之一。当指令低范围连续可变操作时,该控制***基于压力控制装置PCS2、PCS3和PCS4来实施用于第一电机的定子冷却***(MG-A定子冷却)、用于第二电机的定子冷却***(MG-B定子冷却)和第一液压致动离合器(C1)的致动。另外,当指令高范围连续可变操作时,该控制***可操作,以基于压力控制装置的选择性致动实施MG-A定子冷却***、MG-B定子冷却***和第二液压致动离合器C2的致动。当指令低范围状态(包括通过离合器的选择性致动操作于第一、第二和第三固定速比之一)时,该控制***可操作,以基于压力控制装置的选择性致动实施第一、第二和第四液压致动离合器(即,C1、C2、C4)的致动。当指令高范围状态(包括通过离合器的选择性致动操作于第三和第四固定速比之一)时,该控制***可操作,以基于压力控制装置的选择性致动实施第二、第三和第四液压致动离合器(即,C1、C2、C4)的致动。
如上所述,从各第二、第三和第四压力控制装置(即,PCS2、PCS3和PCS4)的流体输出基于第一和第二流量管理阀的指令位置,有选择地对应于四个液压致动离合器和用于MG-A及MG-B的定子冷却***中的一个。因此,当X-阀和Y-阀都指令为低时,PCS2的选择性致动实施向MG-B的定子提供冷却的液压流体流。当X-阀和Y-阀中的一个指令为高时,PCS2的选择性致动实施致动离合器C2的液压流体流。当X-阀和Y-阀都指令为低时,PCS3的选择性致动实施致动离合器C1的液压流体流。当X-阀指令为低,并且Y-阀中指令为高时,PCS3的选择性致动实施向MG-B的定子提供冷却的液压流体流。当X-阀指令为高,并且Y-阀指令为低时,PCS3的选择性致动实施致动离合器C1的液压流体流。当X-阀和Y-阀都指令为高时,PCS3的选择性致动实施致动离合器C3的液压流体流。当X-阀指令为低时,不管Y-阀指令的位置,PCS4的选择性致动都实施向MG-A的定子提供冷却的液压流体流。当X-阀指令为高时,不管Y-阀指令的位置,PCS4的选择性致动都实施致动离合器C4的液压流体流。
现在参考图4中所示的流程图,参考对照图1、2和3及表1和2所述的典型变速器,描述典型变速器和控制***的控制操作的具体方面,包括用于有选择性地控制压力控制装置(即,PCS2、PCS3和PCS4)和流量管理阀X-阀118和Y-阀120,以便提供实施MG-A和MG-B的定子冷却的液压流体流的控制模式。
控制***使用定子温度传感器的信号输入监测定子的操作温度(方框210)。当传感器在MG-A和MG-B的任一定子检测的温度超过预定阈值时,控制***就高潮通过向定子增加液压流体流来提高电机冷却(方框212)。对于该实施例,预定的阈值温度标定在200C的范围内,优选包括基于定子和转子组件以及其它周围组件的材料特性确定的温度,以防止产生组件故障。
为了通过向定子增加液压流体流来提高电机冷却(方框212),确定有效冷却定子所需的总液压流体流率(方框214)。增加液压流体流包括增加通过基本冷却管道中的一个的流量、以及当条件允许时使得流过主动冷却管道中的一个。
所需的总液压流体流率包括足以获得所需离合器容量来通过变速器传递运动扭矩的流量,以及定子冷却流量。定子冷却流量包括通过基本冷却管道的流量,以及当可以时,通过主动冷却管道的流量。其目的是提供足以将定子温度通过从定子至液压流体的热交换,有效降低至低于阈值温度的液压流率,其液压流体随后可通过已知的液压变速器流体冷却装置来冷却。
然后确定流量管理阀118、120是否处于允许通过主动冷却管道来主动冷却电机的位置(方框216)。允许主动电机冷却的流量管理阀位置包括模式I、模式II和中间中的任意一个,如参考表2所述的。当允许主动电机冷却时,确定获得起动主动冷却所需总流量的主压力最小值,包括保持离合器致动的压力(方框218)。主动冷却优选包括操作所选的压力控制螺线管‘PCSn’(即,PCS2、PCS3和PCS4)至全开位置,以实施冷却定子的最大液压流体流(方框220)。主动冷却还包括确定液压***所需的总液压流量,考虑了通过全开的致动压力控制螺线管的液压流量、获得可传递运动扭矩的离合器扭矩容量所需压力所必要的液压流量、以及变速器操作通常必需的任何其它流量(方框226)。该控制***使用PCS1 108调节通过阀107的流量,以获得以所需压力流入液压管道的充足液压流体流,其中所需压力使用调节器109来控制(方框228)。
当不允许主动电机冷却,并且定子温度超过阈值时,保留使用通过基本冷却管道的流量来冷却定子的需求。确定基本冷却流率(方框222)。确定获得通过基本冷却管道来有效冷却定子所需总流量的主压力最小值(方框224)。确定获得实现传递运动扭矩的离合器扭矩容量所需压力的基本冷却、以及变速器操作通常必需的任何其它流量的总液压流率(再次,方框226)。该控制***使用PCS1 108调节通过阀107的流量,以获得以所需压力流入液压管道的充足液压流体流(再次,方框228)。
当定子温度不超过阈值时,使用基准冷却管道来冷却定子(方框212)。基于定子温度确定基本冷却流率(方框222),并确定获得通过基本冷却流量的最小主压力(方框224)。确定液压***所需的总流量,考虑实现传递运动扭矩的离合器扭矩容量的压力所必需的液压率、以及变速器操作通常必需的任何其它流量的总流量(方框226)。该控制***使用PCS1 108和调节器109调节通过阀107的流量,以获得流入液压管道所必需的液压流体流和获得所需的压力(方框228)。
