用于控制具有全轮驱动传动系的车辆的方法
相关申请的交叉引用
本申请要求2017年6月7日递交的美国临时申请No.62/516311的权益，其公开内容如同在此详细充分陈述那样通过引用被合并。
技术领域
本公开涉及一种用于控制具有带有断开式驱动单元的全轮驱动传动系的车辆的方法。
背景技术
该部分提供与本公开相关的背景信息，其不一定为现有技术。
公开号为2010/0038164的美国专利申请公开了一种具有带有断开式驱动单元的全轮驱动传动系的车辆。更具体地，该全轮驱动传动系包括前差速器、动力输出单元和后驱动单元。前差速器被连续驱动以驱动一对前车轮，并向动力输出单元的输入部提供旋转动力。动力输出单元可将旋转动力提供到后驱动单元以驱动一对后车轮。在动力输出单元和后驱动单元中的每个中可采用一个或多个离合器或联接器，用于使动力输出单元的输出部和后驱动单元与前差速器选择性地断开，以允许传动系以前轮驱动模式操作。以这种方式构造传动系可能是有利的，因为其允许传动系在需要那些能力时以全轮驱动(AWD)模式操作，并在不需要全轮驱动能力时为了更好的燃料经济性而以两轮驱动(2WD)模式操作。
应当理解，在车辆操作期间使这种断开式全轮驱动传动系的操作模式在AWD模式和2WD模式之间切换可能是期望的。根据车辆动力系(即，发动机、变速器和扭矩转换器)的构造和传动系的构造，在某些情况下，当传动系的操作模式从AWD模式改变到2WD模式时，车辆可能产生噪声。由此，在本领域中仍然需要用于操作具有带有断开式驱动单元的全轮传动系的车辆的改进的方法。
发明内容
该部分提供公开的大致概要，并不是其全部范围或所有其特征的完全公开。
在一种形式中，本公开提供一种用于操作具有带有断开式驱动单元的全轮驱动传动系的车辆的方法。该方法包括：使所述断开式驱动单元以连接状态操作，以在所述驱动单元的输入部和一对车轮之间传输旋转动力；判定所述驱动单元的操作状态将从所述连接状态改变到断开状态，在所述断开状态，在所述驱动单元的输入部和所述一对车轮之间不传输旋转动力；以及响应于判定所述驱动单元的操作状态将从所述连接状态改变到所述断开状态，响应判定所述车辆的扭矩转换器被解锁的时间段未超过预定时间阈值而将所述驱动单元的操作状态改变到所述断开状态。
在另一中形式中，本公开提供一种用于操作具有带有断开式驱动单元的全轮驱动传动系的车辆的方法。该方法包括：使所述断开式驱动单元以连接状态操作，以在所述驱动单元的输入部和一对车轮之间传输旋转动力；判定所述驱动单元的操作状态将从所述连接状态改变到断开状态，在所述断开状态，在所述驱动单元的输入部和所述一对车轮之间不传输旋转动力；以及响应于判定所述驱动单元的操作状态将从所述连接状态改变到所述断开状态，响应下述情况将所述驱动单元的操作状态改变到所述断开状态：判定所述车辆的速度超过第一预定车辆速度阈值；或者判定所述车辆的速度在小于所述第一预定车辆速度阈值的预定车辆速度范围内，并且判定所述车辆的扭矩转换器已经被解锁的时间段超过预定时间阈值。
进一步的应用领域将根据在此提供的描述变得明显。在此概要中的描述和特定示例仅旨在例示的目的，并且不旨在限制本公开的范围。
附图说明
在此描述的附图仅用于所选实施例而不是所有可能的实施方式的例示目的，并且不旨在限制本公开的范围。
图1是根据本公开的教导控制的具有带有断开式驱动单元的全轮驱动传动系的示例性车辆的示意图；以及
图2是根据本公开的教导的用于操作带有断开式驱动单元的全轮驱动传动系的示例性方法的流程图形式的示意图。
在附图的若干视图中，对应的附图标记始终指示对应的部件。
具体实施方式
示例性车辆10在图1中被示出为具有动力系12和断开式全轮驱动传动系14。动力系12包括诸如内燃机16的原动机、变速器18和设置在内燃机16的输出部与变速器18的输入部之间的扭矩转换器20。断开式全轮驱动传动系14可包括前差速器30、动力输出单元32、传动轴34和后驱动模块36。从变速器18输出的旋转动力可被传输到前差速器30的输入部。动力输出单元32可包括PTU输入构件40、PTU输出构件42和第一断开装置44，PTU输入构件40可被联接到前差速器30的输入部，第一断开装置44可被设置在PTU输入构件40和PTU输出构件42之间的动力传输路径中。传动轴34可将PTU输出构件42联接到后驱动模块36的RDM输入构件50。后驱动模块36可包括后差速器52、第一RDM输出构件54、第二RDM输出构件56和第二断开装置58，第二断开装置58可被设置在RDM输入构件50和第一RDM输出构件54之间的动力传输路径中。断开式全轮驱动传动系14可以断开模式操作，在断开模式，第一断开装置44不在PTU输入构件40和PTU输出构件42之间的第一动力传输路径中传输旋转动力，并且第二断开装置58不在RDM输入构件50和第一RDM输出构件54之间的第二动力传输路径中传输旋转动力。断开式全轮驱动传动系14还可以连接模式操作，在连接模式，第一断开装置44在PTU输入构件40和PTU输出构件42之间的第一动力传输路径中传输旋转动力，并且第二断开装置58在RDM输入构件50和第一RDM输出构件54之间的第二动力传输路径中传输旋转动力。
典型地，当车辆10以超过诸如10、15、20或25英里每小时的预定速度阈值的速度操作时，断开式全轮驱动传动系14的模式从连接模式改变到断开模式。当断开式全轮驱动传动系14的模式从连接模式改变到断开模式时，车辆10的乘坐者可能在某些情况下遭受噪声和振动(根据扭矩转换器20和变速器18的构造)。为了在断开式全轮驱动传动系14从连接模式改变到断开模式时减弱或消除潜在的噪声和振动，断开式全轮驱动传动系14的操作与扭矩转换器20和变速器18中的至少一者的操作协调。
在提供的示例中，断开式全轮驱动传动系14响应于模式改变条件的识别而从连接模式至断开模式的模式改变另外将不会发生，直到扭矩转换器20已经被解锁的时间段大于或等于预定时间阈值。模式改变条件可基于车辆10的速度，和/或可选地还可基于车辆10的各种其它操作参数，诸如转向角和/或车轮打滑。预定时间阈值可被设定至任何期望的量，诸如450毫秒。可替代地，预定时间阈值可被设定至零秒(即，由此仅需要扭矩转换器20处于解锁状态)。
断开式全轮驱动传动系14的操作可另外地或可替代地与变速器18的操作协调，从而断开式全轮驱动传动系14从连接模式至断开模式的模式改变将另外地被协调，使得从连接模式至断开模式的改变不与变速器18中的齿轮传动比之间的转变一致。术语“一致(coincide)”在此旨在包括：在开始齿轮传动比之间的转变所需要的变速器中的离合开始之前的第一预定量的时间，以及在变速器18接合至新选择的齿轮传动比之后的第二预定量的时间。
本公开的方法可由联接到动力系12和断开式全轮驱动传动系14的一个或多个控制器(未具体示出)实现。
参考图2，本方法的另一示例以流程图的形式被示意性例示。该方法可开始于气泡100，并前进到方框102，在方框102，控制使断开式全轮传动系14以连接模式操作。控制可前进到决策方框104。
在决策方框104，控制可判定全轮驱动传动系的操作状态是否将从连接状态改变到断开状态。控制可判定全轮驱动传动系的操作状态是否将基于收到改变全轮驱动传动系的操作状态的请求或通过评估诸如车辆速度等的各种车辆参数而被改变。如果全轮驱动传动系的操作状态将不从连接状态改变到断开状态，则控制可循环回到决策方框104。如果全轮驱动传动系的操作状态将从连接状态改变到断开状态，则控制可前进到决策方框106。
在决策方框106，控制可判定车辆速度是否大于或等于第一预定车辆速度阈值，第一预定车辆速度阈值诸如为10或15英里每小时。如果车辆速度不大于或不等于第一预定车辆速度阈值，则控制循环回到决策方框106。如果车辆速度大于或等于第一预定车辆速度阈值，则控制可前进到决策方框108。
在决策方框108，控制可判定车辆速度是否大于更大的第二预定车辆速度阈值，该更大的第二预定车辆速度阈值诸如是20或25英里每小时。如果车辆速度不大于第二预定车辆速度阈值，则控制可前进到决策方框110。
在决策方框110，控制可判定扭矩转换器已经被解锁的时间是否大于或等于预定时间阈值。预定时间阈值可被设定成任何期望的值，诸如450毫秒。在提供的特定示例中，预定时间阈值被设定成零秒(意味着扭矩转换器仅需要处于解锁状态)。如果扭矩转换器被解锁的时间还未超过预定时间阈值，则控制可循环回到决策方框106。如果扭矩转换器已经被解锁的时间超过预定时间阈值，则控制可前进到方框112。
返回决策方框108，如果车辆速度大于第二预定车辆速度阈值，则控制可前进到决策方框114，在决策方框114，控制可判定车辆速度是否大于比第二预定车辆速度阈值大的第三预定车辆速度阈值，第三阈值车辆速度阈值诸如是45或50英里每小时。在提供的示例中，第三预定车辆速度阈值是54英里每小时。如果车辆速度不大于或不等于第三预定车辆速度阈值，则控制可循环回到决策方框106。如果车辆速度大于或等于第三预定车辆速度阈值，则控制可前进到方框112。
在方框112，控制可使全轮驱动传动系改变操作模式并以断开模式操作。控制可前进到气泡114，在气泡114处控制可结束。
实施例的前述描述已被提供用于例示和描述的目的。其不旨在是详尽的或限制本公开。特定实施例的单独的元件或特征一般地不限于该特定实施例，而是，在适用的情况下能互换并且能够用于所选实施例，即使未特别示出或描述。特定实施例的单独的元件或特征也可以许多方式变化。这种变化不视为偏离本公开，并且所有这种变更旨在包括在本公开的范围内。
