Description

用于机动车辆的动力系及其控制方法
相关申请的交叉引用
本专利申请要求于2019年12月12日提交的申请号为102019000023805的意大利专利申请的优先权，其全部公开内容通过引用并入本文。
技术领域
本发明涉及一种用于机动车辆的动力系和一种用于控制所述动力系的方法。
本发明优选地但不排他地应用于混合动力系，在不丧失任何一般性的情况下，在下文中将以混合动力系为参考。
背景技术
众所周知，混合动力牵引车辆包括内燃发动机和至少一个电机，电机可以用作发电机或用作马达，以根据车辆操作条件与内燃发动机结合(或替代内燃发动机)递送扭矩。
其中使用连接在内燃发动机与车辆传动装置之间的电机的配置常规地被称为“P2”。已知的是，模块化单元设计成插入在车辆的内燃发动机与传动装置之间(因此目前称为“P2模块”)，除了电机之外，模块化单元还包括一个或多个离合器，该一个或多个离合器选择性地将内燃发动机和/或电机以及相关致动器和传动装置元件连接到传动装置。
还已知用于机动车辆的动力系，该动力系设置有布置在内燃发动机的与传动装置相反的一端(通常由“前端”或“P0”表示)上的附件驱动装置。附件驱动装置，通常为带驱动装置，将一个或多个附件连接到曲轴。所述附件典型地包括作为交流发电机和/或马达操作的电机以及用于空调系统的压缩机，并且附件驱动装置包括连接到曲轴和附件中每一者的相应带轮、与上述带轮协作的带以及设计成确保最小带张力的张紧器。
如果电机专门用作交流发电机(发电机)，则通常的做法是在电机与相关带轮之间插入单向接头或自由轮(free wheel)，目的是当电机由发动机驱动时将扭矩从带轮传递到电机，但允许电机在可能发生这种情况的短暂操作条件下(例如在曲轴突然减速的情况下)超控(overide)带轮。这防止了使带经受不希望的张力峰值的电机的高惯性。
另一方面，如果如越来越频繁发生的那样，电机也用作马达，则如上所描述的自由轮的使用是不可能的，因为电机必须能够根据操作条件接收扭矩或将扭矩传递到相关带轮。
在这种情况下，为了确保在所有操作条件下的最小带张力，使用具有作用在电机上游的带跨度上的第一张紧器带轮和作用在电机下游的带跨度上的第二张紧器带轮的双张紧器，因为根据操作条件，两个跨度都可以是松弛跨度。
以上描述的已知的解决方案可以被组合以产生具有处于位置P0的电机(下面：电机P0)和处于位置P2的电机(下面：电机P2)的混合动力系；两个电机可以使用不同的控制策略(例如，一台仅作为马达，另一台以可逆方式)。
此外，内燃发动机可以借助于电机P0、电机P2或者借助于与发动机飞轮(flywheel)相关联的第三电机(传统的起动马达)来起动。
例如，如果电机P0仅用作马达，并且内燃发动机借助于电机P2或起动马达起动，则附件驱动带的张力可以达到不可接受的最小值，如图3所示，这可以确定带的噪音和过早磨损。
发明内容
本发明的目的是生产一种解决上述问题的动力系。
上述目的通过根据权利要求1的附件驱动装置来实现。
本发明还涉及一种根据权利要求6所述的动力系的控制方法。
附图说明
为了更好地理解本发明，通过非限制性示例并参考附图来描述优选实施例，其中：
图1是根据本发明的动力系的示意性平面视图；
图2是根据本发明的动力系的示意性前视图；
图3是示出常规动力系的附件驱动装置中带张力变化的曲线图；和
图4是示出了根据本发明的动力系的附件驱动装置中的带张力变化的曲线图。
具体实施方式
参考图1，数字1总的来说表示机动车辆的动力系。
动力系1包括具有曲轴3和混合动力模块4的内燃发动机2(为了简洁起见，以下称为“热力发动机2”)。
在使用中，混合动力模块4插入在车辆的热力发动机2与传动装置T之间，并且连接到曲轴3的面向传动装置T的一端5。
混合动力模块4包括电机6和设计成选择性地将电机6连接到曲轴3和传动装置T的分离离合器7。
离合器7包括至少离合器盘8以及板10，离合器盘8轴向固定并与连接在曲轴3的端部5处的飞轮9旋转地成一体，板10可轴向移动并与模块4的中间轴11旋转地成一体。离合器7还包括作用在板10上用于控制离合器的液压致动器12。
中间轴11借助于容纳在带轮内的已知类型的扭振减振器(未示出)连接到带轮14。
带轮14通过带15连接到连接到电机6的带轮16。
挠性板17固定到带轮14，所述板构成模块4的输出构件，该输出构件设计成连接到构成传动装置T的输入构件的变矩器(torque converter)18。
动力系1还包括连接到曲轴3的与端部5相反的一个端部20的附件传动装置19。
附件传动装置19(图2)包括固定到曲轴3的端部20的第一带轮21、与第二电机23相关联的第二带轮22和用于驱动调节系统的压缩机25的第三带轮24。三个带轮21、22和24通过带26相互连接。常规张紧器28作用在第二带轮22与第三带轮24之间的带26的跨距26a上。带轮21、22和24沿图3中箭头所示的相同旋转方向R旋转，并且与曲轴3的旋转方向一致。
动力系1包括作为起动马达操作的第三电机30，该第三电机30设置有与飞轮9的齿啮合的输出小齿轮31。便利地，第三电机30为能够快速起动热力发动机2的无刷电机。
动力系1还包括可编程控制单元34，该可编程控制单元34响应于代表动力系1和驱动器控制装置的操作条件的输入信号来控制电机。
动力系1的操作如下。
当离合器7闭合时，中间轴11连接到热力发动机2和电机6以及车辆传动装置T。
在这种情况下，根据操作条件，控制单元34可以将电机6作为发电机(在热牵引期间给电池充电，或者作为再生制动装置)和作为与电机23结合的用于递送附加扭矩(增压)的马达而操作。本文不描述电机的具体控制逻辑，因为它们不构成本发明的一部分。
当离合器7打开时，电机6可以用于电力牵引、电力制动和在热力发动机关闭的情况下滑行(coast)。
热力发动机2借助于第三电机30被起动(冷起动和从电力牵引的条件下起动)。在这个阶段，离合器7被打开。
在热力发动机2起动期间，电机30驱动曲轴3和连接到曲轴3的第一带轮21。
根据本发明，为了防止带26的跨度26c(在带的移动方向上紧挨着第一带轮21的下游)中的张力下降到预定水平以下，电机23由控制单元34操作，以便向带轮22提供有效扭矩。这个附加扭矩导致带26的跨度26c中的张力增加，因此消除了彰显的技术问题。
为了更好地理解根据本发明的附加扭矩的效果，图3和图4示出了常规动力系的附件传动装置和本发明的动力系的附件传动装置中的带26的张力趋势。
特别地，在分别布置在带轮22和24之间、带轮24和21之间以及带轮21和22之间的三个跨度26a、26b和26c中测量张力，并在曲线图中示出为时间的函数。在0至2s之间的时间间隔中，在热力发动机关闭(由电机6驱动)的情况下观察张力的趋势；从2s开始，借助于电动马达30在热力发动机2的起动阶段观察到张力的趋势。
从图3中可以容易地看出，当马达被驱动时，平均带张力值大约为大致350N，在带跨度26c中在起动时出现显著的张力振荡，大约为大致400N峰-峰，其中最小峰值大约为20-30N。在起动时存在由燃烧引起的扭转振动的情况下，基本上由于电机23的惯性的这样的低值可以确定打滑和噪音。
图4示出了在借助电动马达30起动的同时存在由电机23传递到带轮22的附加扭矩的情况下所述张力的趋势。
要传递给带轮22的有效扭矩的值可以容易地通过实验确定。例如，对于排量为1.0升的三缸发动机，所需的有效扭矩仅大约为5Nm。必须仅在发动机的第一次点火循环期间保持有效扭矩；一旦达到稳定的燃烧状态，有效扭矩就不再需要，可以被中断。
从图4可以看出，带26的跨度26c中的张力值增加的效果是明显的，其中最小峰值大约为210N。
最后，清楚的是，可以对所描述的动力系1进行不脱离由权利要求限定的范围的修改和变型。
