Description

用于控制电动、混合动力或燃烧式发动机车辆的动力传动系的传动系状态的方法
技术领域
本发明涉及用于控制混合动力车辆的动力传动系的策略的领域。
目标策略是目的在于通过控制混合动力传动系(PT)的传动系的状态的变化来优化混合动力传动系的运行点的策略。
更精确地，本发明涉及一种用于控制动力传动系的传动系的状态的方法，该动力传动系包括至少一个动力源以及一组联接器和减速器，这些联接器和减速器的对应接合限定了多个传动系状态，这些状态是可通过接合提供转矩的一个或多个能量源、并且通过该一个或多个能量源与车轮的传动比来实现的。
本发明优选地应用于混合动力车辆的PT，该PT包括至少一个燃烧式发动机和一个电动牵引机器，在一个或多个运行模式(即，混合、热或电动运行模式)上具有多个传动比。本发明同样适用于没有电动牵引机器的燃烧式PT。
背景技术
PT的传动系的状态是由特定于所讨论的车辆的体系结构的联接器和减速器的组合限定的。
在常规变速箱情况下，传动系的状态是由(例如一档的)减速器的接合并且由输入离合器的闭合来限定的。在混合动力车辆的情况下，不仅输入离合器(如果有一个的话)和减速器起作用，而且(具体是经由后轮)推动车辆的电动马达也起作用。
在混合PT情况下，主要差异如下：
-燃烧式发动机不再是唯一的动力源，
-对于在车轮处的相同功率而言，可能在由燃烧式发动机传送的功率与由电动牵引机器传送的功率之间有多种不同组合，
-根据所设想的技术定义，电动机器的功率可以是或可以不是通过变速器传输的，
-PT的静态或动态局限性可能取决于电池的电量状态，并且
-电动模式或ZEV“零排放汽车”以与单独的比率相同的方式将一个或多个传动系状态组合。
公开文件US6067495披露了用于将自动变速器的可用比率在固定表格中排名的一种方法。然而，该方法不能够对变速箱的传动系的状态实时排名。
在仅限燃烧式或仅限电动式的PT中，降档仅仅是改变到降低比率(从n到n-1)，例如从第五档到第四档，并且升档仅仅是从n到n+1(例如从第四档到第五内燃)的比率变化。当驾驶员执行降档时，他寻求为他的车辆获得更大的牵引力或使发动机制动(制动或把脚从加速器踏板上移开)。然而，由于可用比率与车轮转矩源的不同的可能组合，燃烧式车辆的齿轮比的简单分级结构(例如，比率1、2、3、4、5和6)不足以对混合动力车辆的传动系的状态加以排名。
此外，对于相同的运行点(速度、动力)，声学现象取决于电动功率与燃烧功率之间的分配。实际上，如果电动机器单独运行，则PT会比如果两种机器(燃烧式和电动式)一同运行时更加安静。
最后，在混合动力车辆情况下，驾驶舒适性(与PT的性能相关联)取决于电池的电量状态。如果电池是充好电的，则可以同时使用由电动机器传送和由燃烧式发动机传送的功率。如果电池是放过电的，则燃烧式发动机是唯一可用的能量源，并且性能可能降低。两个能量源之间的功率的分配是通过能量管理法则来决定的，该能量管理法则引入了根据电池的电量状态来在燃烧式发动机传送的功率与电动机传送的功率之间加以分配。实施这些法则具体是为了满足油耗和去污染要求。
发明内容
本发明的目的是开发车辆的传动系的状态的设定点，从而使得能够优化车辆的声级、驾驶舒适性、降低消耗、以及去污染要求之间所寻求的折衷。
以此目标，本发明提出根据传动系的当前状态定下的其目标状态基于当前状态下与在每个目标状态下可用的动力之间的差异来进行实时排名。
在这些状态中的每一种状态下，优选地基于齿轮比、电动机器和燃烧式发动机能够提供的最大转矩、以及发动机转速或车速来限定最大动力。
附图说明
通过阅读对参照附图给出的本发明的非限制性实施例的以下描述将更好地理解本发明，在附图中：
-图1是所提出的用于对“升”和“退”的传动链状态进行排名的策略的流程图，并且
-图2示出了基于速度针对动力学链的每个状态的可用于车轮的力。
具体实施方式
如以上指明的，由于车轮转矩源和传动比的不同的可能组合，针对燃烧式车辆的变速箱比率建立的传动链状态的排名在混合PT情况下是无效的。策略是基于PT中在这些可用的传动链状态中的每个状态下可用的所有牵引力并且基于相应的车辆体系结构提出的。与常规变速器相类似，术语“升”适用于混合PT的一种目标状态(当这个状态为车轮提供小于当前比率的牵引力的牵引力时)。类似地，术语“退”或降适用于为车轮提供了与当前比率的牵引力相比较更大的牵引力的目标传动链状态。
图1的流程图示出了该策略。第一步骤是计算在当前状态下在车轮处可用的牵引力与在被选为目标的运动链状态下在车轮处可用的牵引力之间的差值。示出了三种情况：
-如果这个差值大于或等于第一经校准的阈值(被称为“阈值_升”)，则该目标状态与当前状态相比较被认为是“升状态”。
-如果这个差值小于或等于第二经校准的阈值(被称为“阈值_退”)，则该目标状态与当前状态相比较被认为是降或“退”状态。
-如果该差值严格大于“阈值_退”并且严格小于“阈值_升”，则可能有两种评估：
a.如果目标状态之前被认为是“退”状态，那么它保持“退”，
b.如果目标动力学链状态之前被认为是“升”状态，那么该状态保持“升”。
这种策略适用于所有混合动力或燃烧式构架，尤其适用于包括燃烧式发动机和电动机器的混合动力变速器，如在公开文件WO2012/131259中所述的混合动力变速器，包括两个同心主轴，每个主轴在连接至车辆的车轮上的副轴上承载了至少一个调低速档小齿轮。这种变速器包括两个联接装置。第一个联接装置可以占用至少三个位置，在这些位置上：
-燃烧式发动机与将电动机器连接至车轮的动力学链解除联接，
-燃烧式发动机在有或没有添加电动机器的情况下以长比率驱动车轮，并且
-燃烧式发动机与电动机器联接以便将它们在车轮方向上的对应转矩相加在一起。
第二联接装置同样可以占用三个位置，即，空挡位置和两个比率接合位置(短的和中间的)。
这一变速器具有三个比率和七个运动学链状态，针对每种状态，图2示出了基于车辆速度的可用力(最大牵引力Fmaxtrs)。这两个第一比率(短的和中间的)是可在电动模式下获得的。它们限定了两种状态“ZEV1”和“ZEV2”。第三比率(或长比率)是可在燃烧模式下获得的。它限定了状态“ICE3”。根据这两个联接装置的位置而可获得四个混合状态：第一混合状态“HY1/1”，在该状态下，这两个主轴联接并且在该状态下转矩落在该短比率；第二混合状态(HY2/2)，在该状态下转矩落在该中间比率；第三混合状态“HY3/1”，在该状态下，这两个主轴解除联接并且在该状态下燃烧式发动机的转矩落在该长比率并且电动马达的转矩落在该短比率；以及第四混合状态“HY3/2”，在该状态下，这两个主轴解除联接并且在该状态下燃烧式发动机的转矩落在该长比率并且电动马达的转矩落在该中间比率。在这些状态中的每一个状态下，最大力是基于相关联的齿轮比、电动机器和燃烧式发动机能够提供的最大转矩、还以及发动机转速或车辆的速度限定的。目标状态根据可用力的差值是正的还是负的而被排名为升或降。下表展示了根据车辆的速度、基于当前状态“HY31”对传动链的目标状态的排名，假设的是前一状态为“HY32”并且这一状态之前被认为是“升”(HY32升)或“降”(HY32降)。
当车辆以30km/h行驶并且当前状态HY31具有比在目标状态HY32下可用的力大1000N的力时，之前为升的该目标状态保持为升(a)。
然而当车辆以50km/h行驶并且当前状态HY31具有比在状态HY32下可用的力小10N的力时，因为差值没有大到足以避免滞后现象(b)，所以后者状态保持为升类型。
当车辆以55km/h行驶并且当前状态HY31具有比在状态HY32下可用的力小200N的力时，后者状态则变为退类型(c)。
当车辆以70km/h行驶并且当前状态HY31具有比在状态HY32下可用的力小1500N的力时，后者状态保持为退类型(d)。
然而当车辆以49km/h行驶并且当前状态HY31具有比在状态HY32下可用的力大10N的力时，因为差值没有大到足以使之变化而不出现滞后，所以后者状态保持为退类型(e)。
当车辆以45km/h行驶并且当前状态HY31具有比在状态HY32下可用的力大200N的力时，后者状态变为升类型(f)。
根据该方法，所有目标状态的排名是基于车辆的移动速度并且基于在当前状态下与在每个目标状态下可用的动力之间的差值实时实施的。
目标状态(以上实例中的HY32)的这种排名或“分型”同样使得能够为被采用为当前比率而实时限定出有待由这一目标状态满足的最低水平或“力约束”。在表格中限定了两个取决于目标状态是“升”的还是“退”的约束级C1或C2。
升比率约束C1优选地大于退比率约束C2。C1与C2之间的距离的目的在于为升转换引入比降转换更大的功率储备，以便不选择在动力设定点的轻微上升情况下存在被放弃的风险的传动链状态。
如果目标状态HY32下的可用的力小于所需要的约束级(用于HY32的C1或C2)，这一状态就不能被采用。在(a)、(b)以及(f)情况下，在状态HY32下可用的力必须大于力约束C1；在其他(c)、(d)以及(f)情况下，为了可采用状态HY32，此力大于约束C2就足够了。
目标状态的排名因此实时确定了为能够被采用为当前状态在每个目标状态下可用的动力的最小水平。升目标比率的最小力水平大于降目标比率的最小力水平。
此表格示出了在具体情况下如何能够控制从一个特定传动链状态(此处是HY31)到另一个状态(HY32)的转换。用所提出的方法，针对状态ICE3、ZEV1、ZEV2、HY1/1、HY2/2、HY3/1、HY3/2之间的所有可能的变化进行这种排名。因此，控制了这些状态之间的所有转换。这一排名对于传动链的最优状态选择是决定性的。
在所描述的实例中，PT具有分布在变速器的三个比率上的七个传动链状态：电动模式下的短比率和中间比率，混合模式下的短比率、中间比率和长比率，以及燃烧模式下的长比率。该方法使得能够控制该链在电动模式下、在混合模式下和在燃烧模式下的不同状态之间的所有转换。
基于其在具有七个标识状态的混合动力变速器的具体情况下的应用加以描述的这种方法通常使得能够通过将提供转矩的一个或多个能量源接合并且通过该一个或多个能量源与车轮的传动比来控制动力传动系的每个传动链状态，该动力传动系包括至少一个动力能量源和一组联接器和减速器，这些联接器和减速器的对应接合限定了多个可达到的链状态。
总体上，该方法可以应用于装备有可与一个或多个传动比一起使用的一个或多个能量源的任何PT，因此使得能够控制电动、混合与燃烧模式之间的多个状态之间的转换。
该方法具有许多优点。首先，它使得能够优化车辆的油耗和去污染。因为PT的电气化主要是由油耗的减少来证明的，所以所实施的策略可以有利地与其能量管理法相互影响。该方法还使得能够在运行期间通过改变的电池的电量状态水平来优化车辆的驾驶舒适性并且还优化所希望的性能。

6.如权利要求3、4或5所述的控制方法，其特征在于，如果该目标状态与该当前状态之间的动力的差值小于一个第二经校准的阈值，则该目标状态与该当前状态相比较被认为是降的。
7.如权利要求5或6所述的控制方法，其特征在于，如果该差值严格大于该第二阈值并且严格小于该第一阈值，则之前被认为是一个“降”状态的目标状态保持为降状态并且之前被认为是一个“升”状态的目标状态保持为升。
8.如上述权利要求之一所述的控制方法，其特征在于，这些目标状态的排名为能够被采用为一个当前状态而实时确定了在每个目标状态下可用的动力的最小水平。
9.如权利要求5所述的控制方法，其特征在于，一个升目标比率的最小力水平大于一个降目标比率的最小力水平。
10.如以上权利要求之一所述的用于动力传动系的控制方法，该动力传动系包括：两个同心主轴，每个主轴承载了在连接至该车辆的车轮的一个副轴上的至少一个调低速档小齿轮；一个第一联接装置，该第一联接装置能够占用三个位置，其中，该燃烧式发动机与将该电动机器联接至这些车轮的运动链解除联接，该燃烧式发动机在有或没有添加该电动机器的情况下以一个长比率驱动这些车轮，以及该燃烧式发动机与该电动机器联接来将它们在这些车轮方向上的对应转矩相加在一起；以及一个第二联接装置，该第二联接装置同样能够占用三个位置，即，一个空挡位置和两个比率接合位置(短的和中间的)；其特征在于，该方法使得能够控制在电动模式、混合模式以及在燃烧模式下在该动力传动系的传动链的不同状态之间的所有转换。
