Description

用于控制车辆变速模式和发动机速度的方法
技术领域
本发明涉及一种车辆的控制方法，更具体涉及一种用于控制换档模式和发动机速度的方法，其中防止车辆离合器过热。
背景技术
一般来说，双离合变速器(DCT)是利用干式离合器传递发动机扭矩的自动变速器类型，其不同于具有扭矩转换器和湿式多盘离合器的普通自动变速器。干式离合器在产生热量期间难以冷却。当干式离合器中的温度升高时，其摩擦力显著降低，因此难以传递功率。此外，当离合器连续打滑时，离合器会受到磨损，因此导致离合器发生故障。
DCT可被实施为具有各种功能以保护离合器免于过热。然而，这些功能的实施会限制车辆的驱动性能，因此，有必要防止车辆进入离合器高温模式。
因此，人们已提出用于监控驾驶者的驾驶倾向、驾驶者主要驾驶车辆的道路条件、和离合器条件的方法，以及用于控制离合器以确保耐久性和可靠性的方法。
在背景技术部分中公开的上述信息仅仅用于增强对本发明背景的理解，因此可能包含不构成在本国中本领域普通技术人员公知的现有技术的信息。
发明内容
本发明正是考虑到以上问题而提出。本发明一方面提供一种车辆的控制方法，其中基于根据所估算的离合器温度的离合器保护逻辑的进入频率来控制换档模式或发动机每分钟转数(RPM)，以防止离合器过热。
根据本发明一个示例性实施例，通过控制器根据估算的离合器温度执行多个离合器保护逻辑中的一个离合器保护逻辑；根据所执行的离合器保护逻辑对控制常数进行计数；以及基于所计数的控制常数，调节换档模式和发动机每分钟转数(RPM)中的至少一个。
在执行多个离合器保护逻辑中的一个离合器保护逻辑的步骤中，如果所估算的离合器温度高于相应的离合器保护逻辑的进入温度值，则可执行相应的离合器保护逻辑。
在对控制常数进行计数的步骤中，当所执行的离合器保护逻辑的进入温度值增大时，控制常数的计数值可增大。
在调节换档模式和发动机每分钟转数中的至少一个的步骤中，控制器可调节升档模式和降档模式，以便当控制常数增大时，以高于当前换档模式的车速进行升档，且以高于当前换档模式的车速进行降档。
在调节换档模式和发动机每分钟转数中的至少一个的步骤中，当控制常数增大时，控制器可将发动机每分钟转数调节成低于当前的发动机每分钟转数。

图5为示出根据本发明实施例的发动机RPM调节的图示。
具体实施方式
现将详细参考本发明的示例性实施方式，在附图中示出这些实施方式的实施例。在任何可能的情况下，在整个附图中使用相同的附图标记表示相同或相似的部件。
图1为示出根据本发明实施例的用于控制车辆变速模式和发动机速度的方法的流程图，图2是示出根据本发明实施例的用于控制车辆变速模式和发动机速度的装置的方框图。
参考图1和图2，用于控制车辆变速模式和发动机速度的方法可包括以下步骤：由控制器140根据所估算的离合器温度执行多个离合器保护逻辑中的一个离合器保护逻辑(S10)；然后，根据所执行的离合器保护逻辑对控制常数进行计数(S20)；由控制器140基于控制常数调节换档模式和发动机每分钟转数(PRM)中的至少一个(S30)。
控制器140接收用于通过发动机控制单元(ECU)130、变速器120等估算离合器110的温度的特征值，以计算离合器110的温度。控制器140可基于所接收的特征值估算离合器110的温度，并执行一个离合器保护逻辑来防止离合器110过热。在本发明中可使用各种常规方法来估算离合器110的温度，因此，在此省略对其的详细描述。
如上所述，控制器140估算离合器110的温度，并基于各个经估算的离合器温度执行一个离合器保护逻辑(S10)。在此，可以根据所估算的离合器110的温度，在各个级执行多个离合器保护逻辑。
在步骤S10中，如果所估算的离合器温度高于相应的进入温度值，则可以执行离合器保护逻辑。
例如，图3是示出根据本发明实施例的多个离合器保护逻辑的图表。参考图3，可以理解的是，车辆根据所估算的离合器110的温度进入不同的保护逻辑。如果至少一个离合器110的估算温度高于200℃，则执行第一级离合器保护逻辑。如果至少一个离合器110的估算温度高于250℃、270℃和300℃，则可分别执行第二级、第三级以及第四级离合器保护逻辑。如果所有离合器110的估算温度高于300℃，则可执行第五级离合器保护逻辑。
以上描述的各个离合器保护逻辑被设置成减小各个离合器110的滑移，以执行对一个离合器110的控制或者执行释放所有离合器110的功能，从而防止离合器110产生热量。进入温度值、释放温度值以及在图3中陈述的各个离合器保护逻辑的功能仅对应于一个示例性实施例，因此，它们可根据制造商或车辆进行变化，而不限于具体值。
根据本发明的控制器140，根据所执行的离合器保护逻辑对控制常数进行计数。也就是说，当控制常数增大时，离合器110的温度更频繁地增加，并且更频繁地执行离合器保护逻辑。例如，如果驾驶者具有执行突然加速和减速的驾驶倾向或者主要在不平整道路上驾驶车辆，则离合器110处于恶劣环境中，离合器保护逻辑可被频繁地执行，因此控制常数增大。
在步骤S20中，当所执行的离合器保护逻辑的进入温度值增大时，控制常数的计数值也增大。
也就是说，随着离合器110的估算温度升高，离合器110的恶劣程度也增加，因此，要计数的控制常数的值需要根据离合器保护逻辑的种类而变化。参考图3，控制常数为根据相应离合器保护逻辑的计数值a、b、c、d和e。当离合器保护逻辑的级数增加时，控制常数的计数值可增加(e>d>c>b>a)。例如，在离合器保护逻辑中，当执行具有最小入口温度值的第一级离合器保护逻辑时，控制常数可被计数为数值1。当所执行的离合器保护逻辑的级数增加时，可以通过对第一级离合器保护逻辑的控制常数的计数值加1，从而对控制常数进行计数。因此，控制常数值增大。在此，仅作为一个实施例来对控制常数进行计数，还可根据车辆和制造商来改变控制常数。
在步骤S30中，可以调节升档模式。因此，当控制常数增加时，以高于当前档位模式的车速执行升档模式。也就是说，当控制常数增大时，甚至当车速增大时，执行换档的时间点变得延迟。因此，即使车速增大，也不是立即地进行升档。此外，可以防止因频繁升档引起的离合器110滑移量增大而导致的离合器110过热。
图4为示出根据本发明实施例的换档模式调节的图，其中由虚线显示的换档模式是指当前的换档模式，由实线显示的换档模式是指调节后的换档模式。
可以理解的是，随着控制常数的增大，沿着朝更大车速的方向调节换档模式。例如，对于从第一档位升档至第二档位的换档模式，以及对于从第二档位升档至第三档位的换档模式，沿更大车速的方向进行调节。未示出的其它升档模式还可以沿更大车速的方向调节。
此外，在步骤S30中，控制器140可调节降档模式。因此，当控制常数增大时，以高于当前换档模式的车速执行降档。
也就是说，当控制常数增大时，驾驶者使车辆突然加速和减速的频率增大。因此，有利于以高扭矩状态驱动发动机。例如，当驾驶者突然对车辆加速时，加速器位置传感器(APS)的开度和车速增大，并且会产生换档至低档位的强制降档(kichdown)。然而，在以此方式调节降档模式时，可通过减小因强制降档换档引起的离合器110的滑移量，来降低强制降档的频率和离合器110过热。
因此，如上所述，当控制常数增大时，根据车速来调节升档和降档模式，因而使因恶劣环境中离合器110的打滑所引起的离合器110的过热最小。
此外，在调节换档模式或发动机RPM中的至少一个的过程中，当控制常数增大时，控制器140可调节发动机RPM，以使其低于当前的发动机RPM。
图5为示出根据本发明实施例的调节发动机每分钟转数(RPM)的图示。参考图5，当APS的开度增大时，发动机的RPM和离合器速度都增大。在图5所示的图示中，发动机RPM线与离合器速度线之间的面积可对应于滑移量。
也就是说，随着控制常数增大，发动机RPM从当前发动机RPM减小，以便减小与离合器速度的速度差，从而使发动机RPM和离合器速度在短时段内相互匹配，因此使离合器110的滑移量最小。从而，可以使离合器110产生的热量最少。
通过上述描述显而易见，在用于控制根据本发明的车辆变速模式和发动机速度的方法中，可以根据离合器保护逻辑的进入频率来调节车辆的变速模式或发动机RPM，从而防止离合器过热以及对离合器造成损害。
尽管已出于示例性的目的公开了本发明的示例性实施例，但是本领域技术人员应该清楚的是，在不背离如在所附权利要求中公开的本发明的范围和精神的情况下，还可以进行各种修改、添加和替代。
