Abstract

本发明涉及一种用于混合动力传动总成(1)的电机(13)的控制方法，以对电力牵引用的一定功率的蓄电池(17)充电。所述控制方法被配置为使得电机(13)从热力发动机(11)中提取出具有上限的提取扭矩，并且所述上限已经减去了驾驶员的设定值以遵守声学约束。根据本发明，当驾驶员的设定值大于扭矩阈值时，所述方法将所述提取扭矩限制为下限以保证对电力牵引用的蓄电池(17)的充电。

Description

根据驾驶员的设定值控制混合动力传动总成的电机的方法
技术领域
本发明的领域涉及用于根据驾驶员的设定值控制混合动力传动总成的电机以遵守声学约束并且保证蓄电池的充电水平的方法。
背景技术
混合动力车辆的动力传动总成存在大量的架构。其中一种架构包括：与前桥联接的牵引用的热力机、由大功率蓄电池供电且与后桥或前桥联接的牵引用的电机以及适于从发动机扭矩中提取出提取扭矩以对蓄电池充电的电机，其中所述发动机扭矩由牵引用的的热力发动机提供。出于驾驶的舒适性的目的，不断研究以减少由动力传动总成产生并主要由热力发动机发出的声学噪声和振动噪声。然而，在行驶过程中对蓄电池充电提高了热力发动机的负荷并因此增大了噪声和振动。
一种已知的解决方法在于，使充电水平与驾驶员的驾驶相适应以便由热力发动机提供的总发动机扭矩不超过扭矩的最高限度。所述最高限度被选取以遵守乘客所能够接受的声学约束(contrainte)和振动约束。此外，所述动力传动总成被配置为：当驾驶员的设定值增大时，减小提取扭矩。但是，该解决方法延长了充电时间，因此这样减少了在车辆的纯电动模式下的行驶时间。
还已知，专利US6,137,250描述了一种对牵引用的电机供能的发电机的传动装置所排他地专用的热力发动机的起动的控制方法。所述方法规定了当允许满足动力传动总成的噪声及振动的行驶状况出现时热力发动机的起动或停止。尽管该控制方法有利，但是其仅能应用于混合动力类的架构。
发明内容
因此，存在提高混合动力车辆的充电能力的需求及提出驾驶员和乘客所能够接受的声学危害和振动危害水平的需求。还要为了以下目标寻求解决方法：更先进的混合动力架构，尤其是在这些混合动力架构中通过部分地提取出车辆的牵引用的热力发动机的扭矩的方式来实现充电。
更确切地，本发明涉及机动车辆的混合动力传动总成的第一电机的控制方法，所述机动车辆包括牵引用的热力发动机以及由蓄电池供电的牵引用的第二电机，其中，牵引用的热力发动机提供经计算的发动机扭矩以至少满足作用在车轮的扭矩所专用的驾驶员的设定扭矩的需求且满足少用于对蓄电池充电的第一电机所提取的提取扭矩的需求，所述提取扭矩被控制为第一设定值，所述第一设定值等于预定的扭矩的上限，所述预定的扭矩的上限已经减去了驾驶员的设定扭矩。根据本发明，当驾驶员的设定扭矩大于预定阈值时，提取扭矩被控制为第二设定值，所述第二设定值等于预定的扭矩的下限。
有利地，扭矩的上限被配置为使得动力传动总成所产生的声学噪声小于预定声学约束。
有利地，扭矩的下限被配置为使得提取扭矩所提供的蓄电池的充电水平等于蓄电池的预定充电水平。
在变型中，所述上限和所述下限在车辆的速度小于车辆的速度阈值时为定值。
在变型中，所述下限和所述上限在车辆以大于速度阈值的速度行驶时根据车辆的速度的值而增大。
在变型中，扭矩阈值被配置为使得其等于所述上限和所述下限之间的扭矩差。
根据本发明，还提供一种包括混合动力传动总成的机动车辆，所述混合动力传动总成被配置为用于实施上文所述的方法的实施例中的任一个实施例。
由于本发明，电力牵引所专用的蓄电池的充电水平在驾驶员的设定值增大时被维持在一个足够的水平上。由于驾驶员带着强烈的意愿踩在加速踏板上，该控制功能准许热力发动机所提供的总发动机扭矩的增大。考虑到动力传动总成的声学准则，因为所述噪声的增大是与驾驶员的扭矩需求相关联的，所以在这种情况下驾驶室中所感受到的动力传动总成的噪声的增大是可接受的。

具体实施方式
本发明特别涉及混合动力电动车辆。车辆优选地但非必需地是对外部电网可充电的车辆。本发明提出了适于对牵引用的第二电机供电所专用的大功率蓄电池充电的第一电机的控制方法。所述控制方法用以限制动力传动总成的声学危害和振动危害，尤其是在驾驶员的设定值增大的情况下降低充电。然而，本方法确保了蓄电池的最低充电水平以对车辆的电力牵引供电，有利地，根据驾驶员的设定值来控制所述最低充电水平，以不妨碍驾驶员。
首先，描述适合实施根据本发明的控制方法的动力传动总成架构。图1和图1b示出了这种动力传动总成的示意图的示例。在图1中，混合动力传动总成1包括：对蓄电池16、17充电的第一电机13、由牵引用的热力发动机11牵引的第一前车轮总成以及由牵引用的第二电机19牵引的第二后车轮总成。
在图1中，前车轮总成与变速器10连接，该变速器实现车轮与热力发动机11之间的传动。所述热力发动机11适于通过例如为传动皮带或联接装置的传动装置12驱动第一电机13。热力发动机11提供被分配以尤其用于满足作用于车轮的驾驶员的设定扭矩的需求和充电的需求的发动机扭矩。起动器14也能够提供对热力发动机11的起动的辅助作用。在变型中，动力传动总成1未配备有辅助起动器14。
在发电机工作期间，第一电机13由热力发动机11驱动并从热力发动机11的发动机扭矩中提取出提取扭矩。第一电机13的提取扭矩经计算为使得其一方面满足车载网络和车辆设备的供电需求，另一方面满足电力牵引的需求。还设置为，在某些行驶情况下例如在热力发动机11的起动阶段中，第一电机13能够像电动机一样运行。
此外，动力传动总成1包括连接到低压电网上的蓄电池17，第一电机13和牵引用的第二电机19在低压电网上经由换流器18连接。第一电机13和牵引用的第二电机19适于对蓄电池17充电以满足动力传动总成1的电力牵引的需求。
电压转换器15一方面连接到低压网上，一方面连接到超低压网上。超低压网对第二蓄电池16、车载网络以及起动器14供电。应当注意，超低压网主要由第一电机13供电以维持蓄电池16中足够的能量水平并保证车载网络的正常运行。
确切的说，通过本发明实施的第一电机13的控制方法尤其涉及电力牵引的充电的需求所专用的提取扭矩的计算。说明书的下文中描述的提取扭矩涉及经计算以用于对为牵引用的第二电机19供电的蓄电池17进行充电的扭矩。
更确切地，动力传动总成1的电力牵引包括与后桥总成联接的牵引用的第二电机19。包括联接装置191的传动器将牵引用的第二电机机械地连接到后桥总成的车轮上。牵引用的第二电机19是可逆电机，所述第二电机通过其转子的结构可以在车辆的加速过程中为车轮提供扭矩，或者可以在车辆的减速过程中提供用于充电的扭矩。还应注意到，由牵引用的第二电机19牵引的后桥总成与由热力发动机11牵引的前桥总成在机械上是独立的。
确切地说，其它混合动力传动总成的架构也适于实施根据本发明的控制方法。例如，在图1b示出的变型中，动力传动总成1区别于图1中所示出的动力传动总成，因为牵引用的第二电机19及牵引用的热力发动机11与同一车轮总成联接。图1b中，组成动力传动总成1的元件通过与图1相同的附图标记示出。机械传动器的适配及电机的提取扭矩的计算能够由本领域技术人员进行适配而不会超出本发明的范围。
更确切地，图2示出了根据本发明的能够维持蓄电池17的充电水平的电机13的控制方法的实施例。在由附图标记“MTH停止”表示的初始步骤E0中，热力发动机11停止，第一电机13不处于充电状况。当热力发动机11起动(即在图中与附图标记Cd1对应的事件)时，第一电机13可以从热力发动机11提供的扭矩中提取出提取扭矩。然而，对提取扭矩Cprev的操作可能以其它参数为条件，例如充电的需求、蓄电池17的充电水平、热力发动机的运转情况、发动机扭矩的水平以及发动机转速。
假定，对提取扭矩Cprev的操作的条件同时具备以控制所述提取扭矩，为了限制动力传动总成1的噪声水平，在步骤E1中，第一电机13被控制为使得提取扭矩Cprev被控制为第一设定值CS1，所述第一设定值等于预定的扭矩的上限Lsup，预定的扭矩的上限已经减去了驾驶员的设定扭矩Ccond。所述上限至少确保对一定功率的蓄电池17的充电。
已知，由热力发动机11提供的扭矩经计算以满足与驾驶员的加速或减速以达到期望车速的意愿对应的驾驶员的设定扭矩的需求，且满足蓄电池17的充电需求和车载网络的供电需求。因此，由热力发动机11提供的发动机扭矩等于提取扭矩Cprev和驾驶员的设定扭矩Ccond之和。在步骤E1中，发动机扭矩被限定为预定的扭矩的上限，这是由于已经从提取扭矩Cprev中删除了与乘客所能接受的动力传动总成的声学噪声水平相应的驾驶员的设定扭矩。
当满足条件Cd2时，即对应的在驾驶员的设定扭矩大于预定的扭矩阈值SC的情况下，所述方法被配置为进行步骤E2，使得提取扭矩Cprev被控制为第二设定值CS2，所述第二设定值等于预定的扭矩的下限Linf。被视为底限的该下限阻止提取扭矩Cprev的持续降低并能够确保对蓄电池17的充电。在这种情况下，因为驾驶员是带着强烈的意愿踩在加速踏板上，所以由热力发动机11提供的总发动机扭矩的增大从声学的角度而言是可以接受的。因为所述噪声的增大与驾驶员的扭矩需求相关联，所以驾驶室中所感受到的动力传动总成的噪声的增大在这种情况下是可以接受的。
更确切地，扭矩的下限Linf被配置为使得由提取扭矩Cprev提供的蓄电池17的充电水平等于蓄电池17的预定充电水平。
此外，扭矩阈值SC被配置为使得其等于所述上限Lsup与所述下限Linf之间的扭矩差。扭矩阈值在配置电机13的控制功能时被预定并且与驾驶员用来施加强烈需求的加速踏板的位置对应。该配置还确保了提取扭矩的连续性，从而在扭矩阈值SC改变时不会导致扭矩发生剧烈变化。
当热力发动机11停止(对应的事件为条件Cd1或Cd3的控制)时，本方法返回初始步骤E0。
此外，设定为：上限Lsup和下限Linf在车辆的速度小于例如确定为25km/h的车辆的速度阈值时为定值。从行驶的噪声方面和空气动力噪声方面来看，在较低的速度时，动力传动总成的噪声是主要噪声。这些恒定的上限和下限保证了在声学上的控制。然而，该方法被配置为使得：下限Linf和上限Lsup在车辆以大于速度阈值的速度行驶时根据车辆的速度的数值而增大。因此，该方法利用空气动力噪声和行驶的噪声来提高蓄电池17的充电水平。
作为非限制性的示例，图3示出了在驾驶员的设定扭矩Ccond增大的情况下的第一电机13的提取扭矩Cprev。在横轴上示出了驾驶员的设定扭矩Ccond和扭矩阈值SC，所述扭矩阈值例如确定为30N.m。在纵轴上，以N.m为单位示出了由虚线表示的提取扭矩Cprev，由实线表示的扭矩的下限Linf和扭矩的上限Lsup。作为非限制性的示例，下限Linf和上限Lsup分别为30N.m和60N.m的定值。应当注意，上限Lsup和下限Linf对应于至少确保对蓄电池17的充电并且在有需要的情况下确保车载网络的最低需求的充电水平。此外，发动机扭矩Cmth由第二条虚线表示。如上文提及，发动机扭矩Cmth等于提取扭矩Cprev与驾驶员的设定扭矩Ccond之和。
当驾驶员的设定扭矩为零时，所述提取扭矩Cprev等于上限Lsup，并且等于热力发动机的发动机扭矩。这允许将动力传动总成的噪声控制为以可接受的水平发出。
当驾驶员的设定扭矩增大时，提取扭矩Cprev减小，且发动机扭矩Cmth保持恒定，且所述发动机扭矩的水平一直恒定为等于由声学约束限定的上限Lsup的水平。
当驾驶员的设定扭矩Ccond大于扭矩阈值SC时，提取扭矩Cprev被限制为下限Linf。所述下限Linf至少确保蓄电池17的充电水平。
图4示出了混合动力传动总成1的监测装置30，并且更确切地，图4示出了第一电机的控制方法的功能。所述监测装置30包括计算装置31，所述计算装置用于根据与驾驶员的设定扭矩Ccond和充电的设定值Crec对应的参数来确定第一设定值CS1的数值和第二设定值CS2的数值，充电的设定值可以是尤其取决于蓄电池17的充电水平的充电触发信号。计算装置31包括输入接口和输出接口，所述输入接口用于获取所述参数，而所述输出接口用于将扭矩的设定值CS1、CS2发送到第一电机13的控制装置32的输出接口。
所述监测装置30还包括将提取扭矩Cprev的设定值发送到第一电机13的控制装置32。特别地，控制装置由作为参数的驾驶员的设定扭矩和预定的扭矩阈值SC来控制，以按照扭矩的第一设定值CS1或扭矩的第二设定值CS2来控制第一电机13。
应当注意，驾驶员的设定扭矩Ccond由监测装置根据加速踏板的位置并且如有必要根据车辆的行驶性能的参数(例如，驾驶的运动模式或者经济模式)来确定。此外，用于控制扭矩的第一设定值CS1或扭矩的第二设定值CS2的预定的扭矩阈值SC是在监测装置30的存储器中存储并且在第一电机13的控制程序中使用的参数。在说明书中，上文提及的用以增大下限和上限的速度阈值也是在监测装置30中存储的参数。
