Abstract

一种启动发动机的方法，包括：在转动曲柄发动发动机之前，通过经由离合器将具有小于发动机起动扭矩的量值的扭矩从电动机传递至弹簧而预加载扭振减震器的弹簧、增加离合器的扭矩容量以及利用电机响应于启动发动机的命令转动曲柄发动发动机。

Description

利用预加载的减震器弹簧的混合动力车辆发动机启动方法
技术领域
本发明总体上涉及一种通过经由离合器和减震器将扭矩从起动电动机传递至发动机而启动混合动力车辆(HEV)的发动机的方法。
背景技术
模块化混合动力传动系统(MHT)是一种产生并联式混合电力驱动(HEV)的传动系统组件的布置形式。传动系统包括串联设置在发动机与变速器之间的扭振减震器(torsion damper)、输送泵、电机以及液力变矩器。
在发动机重新启动期间，扭振减震器由于用于转动曲柄起动发动机的巨大的扭矩而会发生触底或振动。减震器的这样的触底会损坏飞轮或者对应当始终如一的发动机重启的控制产生不利影响。发动机重启可以使用双质量飞轮。
发明内容
一种启动发动机的方法，包括：在转动曲柄起动发动机之前通过经由离合器将具有小于发动机起动扭矩(engine cranking torque)的量值的扭矩从电动机传递至弹簧而预加载扭振减震器的弹簧、增加离合器的扭矩容量以及利用电动机响应于启动发动机的命令转动曲柄发动发动机。
本方法减少启动时的发动机振动，并减少发动机启动时的可变性。
本方法通过消除当发动机控制器发出启动发动机的命令之后产生弹簧位移的需要而减少了发动机启动时长。当发动机重新启动即将发生时，减震器通过分离离合器预加载。
优选实施例的应用范围将从下面的详细的说明书、权利要求书和附图中变得显而易见。应当理解的是，说明书和具体示例，尽管表明了本发明的优选实施例，但仅以举例的方式给出。对描述的实施例和示例进行多种变化和修改对所属技术领域的技术人员来说将是显而易见的。
附图说明
通过参考下面的说明，结合附图，本发明将会更容易理解，附图中：
图1为显示与HEV的传动系统相关的组件的布置的示意图；
图2显示了启动图1的发动机的方法的步骤；以及
图3为显示在本发动机启动方法期间弹簧位移与弹簧扭矩的变化的图表。
具体实施方式
图1说明了传动系统10组件的MHT配置，它包括内燃发动机12、发动机分离离合器14、高压电池16、高压到低压DC/DC转换器18、低压电池20、低压启动器22、扭转减震器24、电机26、液力变矩器28、液力变矩器旁路离合器30、齿轮变速箱32、传动轴34、主减速器齿轮(finaldrive gearing)36、半轴38、40，以及从动轮42、44。
扭振减震器24包含螺旋弹簧或者包括多个螺旋弹簧的机械装置，其中应用于减震器的扭矩导致该弹簧机械装置的位移。
由电机26驱动的主输送泵46向齿轮变速箱32的液压系统以及液力变矩器28供应加压的液压流体。由电动机(未示出)驱动的辅助油泵48在发动机关闭时向齿轮变速箱32的液压系统和液力变矩器28供应加压的液压流体。
内燃发动机(ICE)12通过分离离合器14连接到电机26和齿轮变速箱32，分离离合器14能够接合和分离发动机与传动系统，以满足混合动力车辆在不同模式下的操作要求。
高压电机26固定在液力变矩器28的叶轮轴50上。电机26由高压电池16供电。
HEV传动系统10可以共享与传统车辆相同的变速器硬件，但是HEV传动系统10采用不同的控制算法，比如，常规的阶比变速器(step ratiotransmission)可以用在该传动系统中以驱动车辆。
用在本配置中的液力变矩器28优选与传统自动变速器中用到的液力变矩器完全相同。当旁路离合器30打开时，在变速器输入轴52与叶轮轴50之间具有差速是可能的。当旁路离合器30关闭时，液力变矩器叶轮与涡轮机械地连接，在这种情况下，电机26的转速与变速器输入52实质上完全相同。
作为选择，其它类型的自动变速器可以用在MHT传动系统10中，例如，具有与两个皮带轮接合的传动皮带的无级变速器(CVT)，或手自一体变速器。总体的混合动力操作是相似的，但是将电动机与变速器分离的机械装置的细节是不同的。
扭振减震器24是具有调整或消除来自传动系统10的高频扭转振动的主要功能的机械组件。发动机12通过高压电机26转动曲柄发动而启动。
为了达到发动机启动的最小扭矩，减震器24中的弹簧被扭转地盘卷至参考角位移。弹簧的角位移足够之前需要几百毫秒的一段时间。在这个时间段内，减震器弹簧存储由电机26传递的势能。在此过程中弹簧的这样的角位移在齿轮启动器电机用于直接转动曲柄发动发动机的传统车辆传动系统中是不存在的。
图2所示为传统传动系统的发动机启动的连续的步骤或者阶段。通过产生减震器的弹簧机构的角位移，存储减震器中的势能发生在第一阶段60。减震器弹簧机构优选具有两级弹性刚度，如图3所示。第一级弹簧常数62低于弹簧常数72，以使相当大的弹簧位移——角位移或轴向位移——发生。
通过在发动机控制器发出代表启动发动机12的命令的信号后执行的发动机启动方法步骤中消除第一阶段60，以此缩短传动系统10中发动机启动所需要的时期。该时间期缩短了是因为当发动机启动即将发生时并且在转动曲柄发动发动机之前，传动系统控制器优选使用液压驱动分离离合器14以产生离合器14的扭矩传递容量64，使得利用通过离合器14从充当起动电动机的电机26传递的势能预加载减震器24的弹簧机构。
在离合器14上的预加载扭矩应该略小于从静止状态位置转动发动机曲轴68所需的最小扭矩66，也就是说，小于发动机起动扭矩。参考发动机曲轴68的静摩擦扭矩、发动机辅助负载以及发动机的活塞压缩发动机汽缸70内空气所需的扭矩确定起动发动机12的最小扭矩66。
当发动机启动由控制系统给出命令时，离合器14的扭矩容量充分增加，这样，离合器可以经由减震器24将具有大于发动机起动扭矩66的量值的扭矩从电机26传递到发动机曲轴68。减震器24可以具有第二操作范围，该操作范围的弹簧常数72大于弹簧常数62。但是，尽管发动机12被起到起动电动机26的作用的电机转动曲柄发动，但不管减震器24的弹簧常数是多少，减震器24的弹簧常数在最低范围62内。
当应用到发动机12的曲轴的扭矩的量值超过发动机启动的最小扭矩时，发动机12进入起动阶段74。此后，燃料76供应给发动机12，控制发动机转速(阶段78)为发动机怠速，从而完成发动机启动程序。
低压启动器22用于当没有电力时启动发动机，比如当高压电池16的电荷不足以如描述的那样通过电机26、离合器14和减震器24的操作来转动曲柄发动并启动发动机的时候。
根据专利法规的规定，已经对优选实施例进行了说明。然而，应当注意的是除了具体说明和描述之外，可以实施替换的实施例。
