Abstract
本发明涉及一种混合动力车辆。混合动力车的电动机-发电机旋转轴被连接到一个转矩变换器的输出轴,后者连接到内燃发动机的输出轴。在转矩变换器随变速控制而产生滑差的时间段内,通过按电动机或发电机模式控制电动机-发电机来辅助车辆的加速或减速控制。
Description
技术领域
本发明涉及装备有内燃发动机和电动机-发电机的一种混合动力车。本发明涉及一种实现混合动力车的技术,在具有包括转矩变换器和多级变速器的一个动力变速器系统的车上安装作为动力源的一个内燃发动机和一个电动机-发电机。本发明涉及改善混合动力车的驱动性能,并且降低因车辆的转矩变换器造成的能量损失。
背景技术
为了在广阔速度范围内有效利用车辆内燃发动机的转矩作为其动力源,在动力源和车轴之间设有变速器。此外,具有自动变速器、在驾驶中不需要用离合器踏板换档的车也在日益普及,当今几乎所有的驾驶员都熟悉这样的自动变速器。
尽管行星齿轮式变速器或无级变速式变速器都属于自动变速器,还有一种广泛使用的具有液压转矩变换器和与液压转矩变换器串联组合的多级变速器的自动变速器系统。多级变速器具有这样的结构,按照来自程序控制电路的控制信号,自动控制机械变速操作。此类变速器对设计和制造以及驾驶员座位处的变换杆结构等有所改进,其设计对提高操作性能非常合理。在这种环境中,有可能按合理的价格提供极为可靠的变速器,这明显改善了车的驾驶性能。
日本专利JP2000-203287A(Toyota)公开了一种混合动力车,所采用的变速器包括液压转矩变换器和与液压转矩变换器组合的机械多级变速器。JP2000-203287A中所公开的变速器的主要目的是在再生发电制动中防止电动机-发电机的转轴超速。迄今为止,安装有包括和机械多级变速器组合的液压转矩变换器的变速器的混合动力车还没有作为实用的车辆出售。
在车辆加速或减速或是在执行变速操作时,在液压转矩变换器中,转矩变换器的输入轴和输出轴之间存在滑差。在转矩变换器的输入轴和输出轴之间传送动力时也会产生这种滑差。借助于滑差,就能随着速度变化平滑地执行转矩变换。然而,转矩变换器会因滑差而发热,因而有能量损失。为了减少与机械多级变速器和动力变速器系统串联连接的液压转矩变换器的滑差,考虑到在其输入轴与输出轴之间的转速差小于预定值时,用一个机构机械锁定转矩变换器的输入轴和输出轴。利用这种机构,就能防止转矩变换器持续发热。这种机构因而得到了广泛的应用。
上述的液压转矩变换器是一种利用二者之间的滑差来控制输入轴和输出轴的装置,使得输入轴和输出轴之间的转速差变小。因此,只要车辆采用这种转矩变换器,理论上就必然会增加车辆特定燃料的消耗。也就是说,采用液压转矩变换器与通过采用内燃发动机和电动机-发电机的混合动力来明显改善燃料经济性彼此是有矛盾的。因而,可以说在混合动力车中尚未使用包括液压转矩变换器的变速器。
发明内容
本发明的发明人注意到这样的事实,即使在转矩变换器的输入轴和输出轴之间存在滑差,也能制造出能量损失随滑差减少的混合动力车。
本发明的目的是提供一种混合动力车,即使在变速器中使用转矩变换器,也能够减少转矩变换器特别是液压转矩变换器的能量损失。本发明的另一目的是提供一种具有优异驾驶性能的混合动力车。本发明的再一目的是提供一种装备有带跟踪记录的变速器的混合动力车。本发明的又一目的是提供一种装备有多数驾驶员能熟练操作的变速器的混合动力车。
在按照本发明的混合动力车中,转矩变换器和多级变速器与动力变速器系统串联连接在内燃发动机的输出轴和用来驱动车轴的一个推进轴之间。也就是说,转矩变换器的输入轴被直接连接到内燃发动机的输出轴,而多级变速器的输入轴被连接到转矩变换器的输出轴。推进轴被连接到多级变速器的输出轴。
另外,电动机-发电机的转轴被藕合到转矩变换器的输出轴一侧。提供给电动机-发电机的励磁电流受程序控制电路的控制,电动机-发电机根据这一控制作为电动机或发电机工作。在电动机-发电机按电动机工作的电动机模式下,安装在车上的蓄电池向电动机-发电机供应电能,并且向转矩变换器的输出轴一侧提供旋转动力。在电动机-发电机按发电机工作的发电机模式下,从转矩变换器的输出轴或是通过多级变速器从推进轴向电动机-发电机提供旋转动力。动能被变换成电能对安装在车上的蓄电池充电。
若是在转矩变换器中产生滑差,连接到转矩变换器输出轴一侧的电动机-发电机就工作以减少滑差。也就是说,车的运行负荷被施加在转矩变换器的输出轴一侧。若是在连接到转矩变换器输入轴一侧的内燃发动机转速反抗运行负荷而上升的模式下产生滑差,电动机-发电机就在程序控制电路的控制下切换到电动机模式。由电动机产生的旋转动力变成转矩变换器的输出轴也就是推进轴加速旋转的辅助动力。在这种情况下,电动机-发电机所需的电能是由车辆的蓄电池提供的。
另一方面,在转矩变换器输出轴的转速超过其连接到内燃发动机输出轴的输入轴转速并且车辆进入发动机制动模式时,若是在转矩变换器的输出轴与输入轴之间产生滑差,程序控制电路就控制电动机-发电机按发电机方式工作。发电机对车辆形成电气制动状态,并且将旋转能量变换成电能。由电动机-发电机产生的电能重新对车辆的蓄电池充电。
按照这种控制方式,即使在转矩变换器的输入轴和输出轴之间存在转速差,仍有可能这样来控制车辆,使得大部分这种转速差转变成转矩变换器内部的机械阻力而不会影响到变换器电路。也就是说,即使在转矩变换器的输入轴和输出轴之间存在转速差,在转矩变换器内部传送的动力也很小,从而有可能控制变换器电路,使得在转矩变换器内部基本上没有机械阻力。这样,转矩变换器内部的发热就很少,而转矩变换器的动能损失就很小。
即使在转矩变换器中存在滑差,执行这样的控制也能用电动力使车辆加速,或是在滑差变小的方向上,通过用电气制动使车辆减速。对变换器电路的这种控制一直持续到转矩变换器的滑差变小并且转矩变换器被锁定。
也就是说,在具有内燃发动机,其输入轴连接到内燃发动机输出轴的转矩变换器,连接到转矩变换器输出轴的多级变速器,电动机-发电机,蓄电池,用来在蓄电池和电动机-发电机之间双向传输电能的变换器电路,以及用来控制变换器电路的程序控制电路的这种混合动力车中,本发明的特征在于电动机-发电机的转轴被连接到转矩变换器的输出轴一侧,而程序控制电路包括一个控制装置,用来在车辆行驶中改变多级变速器的过程中在转矩变换器内产生滑差的时间周期阶段,使电动机-发电机相对于车轴共享正、负转矩。
控制装置中包括一个装置,从检测到转矩变换器输出轴的转速小于其输入轴转速并且产生滑差的时刻到对其执行锁定的时刻的一个时间周期中,按电动机操作电动机-发电机。这种模式是混合动力车的辅助加速模式。控制装置还包括一个装置,用于在从检测到转矩变换器输出轴的转速大于其输入轴转速并且产生滑差的时刻到对其执行锁定的时刻的一个时间周期中,按发电机操作电动机-发电机。这种模式是混合动力车的再生发电制动模式。
附图说明
以下要参照附图举例说明本发明的具体实施例,在附图中:
图1的方框图表示按照本发明一个实施例的混合动力车的结构;并且
图2是图1所示实施例的控制流程图。
具体实施方式
图1的方框图表示按照本发明一个实施例的混合动力车的结构。内燃发动机1的输出轴被直接连接到液压转矩变换器2的输入轴.液压转矩变换器2的输出轴通过一个耦合单元9被固定连接到多级变速器3的输入轴。多级变速器3包括用来机械控制多级变速器3的换档-组合的一个致动器31,以及用于电气控制致动器的变速器控制电路32。变速器控制电路32包括一个程序控制电路(ECU)。
变速器控制电路32按照包括车速、发动机转速、加速踏板的操作信息等输入信息确定多级变速器的最佳齿轮比。致动器31按照变速器控制电路32的控制输出机械控制多级变速器3的变速器操作。致动器是公知的类型。本实施例中的多级变速器3是具有4个正向驱动档和1个反向驱动档的公知的标准变速器。
液压转矩变换器2通过流体在其输入轴(在内燃发动机一侧)和输出轴(在变速器一侧)之间双向传送旋转动力。若是在液压转矩变换器的输入轴和输出轴之间存在转速差,液压转矩变换器就在传送转矩的同时减少这一转速差,若是转速差下降到一个预定值(预定比例),就按照变速器控制电路32的控制机械锁定输入轴和输出轴。由于工作方式如上所述的这种液压转矩变换器的结构是公知的,在此省略对其细节的描述。在传动轴4上设有一个速度传感器,并在这一机构中的各个旋转部位设有旋转传感器。由这些旋转传感器产生的旋转信息被提供给变速器控制电路32。由于这些旋转传感器及其线路会造成附图复杂化,在图1中没有表示。
图1中的电动机-发电机5是一个三相AC旋转机器。电动机-发电机5在提供给电动机-发电机励磁绕组的三相AC电流的旋转相位速度大于机械旋转速度时,按照电动机工作,而在提供给电动机-发电机励磁绕组的三相AC电流的旋转相位速度小于机械旋转速度时,按照发电机工作。变换器电路8在从各种旋转传感器获得旋转信息的程序控制电路6的控制下产生旋转相位。变换器电路8的DC端子被连接到蓄电池7。本实施例中的蓄电池7是一个镍氢电池。由于变换器电路8的结构及其在混合动力车中的相位控制是公知的,在此省略对其细节的描述。
诸如汽油或柴油等液体燃料通过燃料泵11供应给内燃发动机1。燃料泵11受一个发动机控制电路12的控制。来自混合动力车的加速踏板的踏板操作状态信息被提供给发动机控制电路12。发动机控制电路12,用来执行混合动力车能量控制的程序控制电路6,以及用来控制变速器的变速器控制电路32都被连接到一条单独的连接总线14,以便它们可以共用各自的信息。由于这些结构也是公知的,在此省略了具体的说明。
本发明特有的结构体现在电动机-发电机5的旋转轴被连接到液压转矩变换器2的输出轴一侧。在此实施例中,在液压转矩变换器2的输出轴上设有耦合单元9,并且电动机-发电机5的旋转轴通过耦合单元9固定连接到液压转矩变换器2的输出轴上。在这一耦合齿轮中设定对应着内燃发动机1特性和电动机-发电机5特性的适当齿轮比。此外,在这一耦合单元9中,液压转矩变换器2的输出轴还直接连接到多级变速器3的输入轴。
本发明的特征还在于程序控制电路6的控制操作是控制混合动力。也就是说,在车辆行驶过程中,在变速器控制电路32的控制下,用多级变速器3的一个轴执行操作的定时抵消液压转矩变换器2的锁定。并且在变速器控制电路32和致动器31的控制下,在多级变速器3中设定一个新的齿轮比。在混合动力车按照多级变速器3新设定的齿轮比加速或减速时,就会形成可能在液压转矩变换器2中产生滑差的状态。当程序控制电路6从旋转传感器(因上述理由没有表示)的输出检测到这一滑差时,程序控制电路就将电动机-发电机5设定在辅助加速模式或再生发电制动模式。
也就是说,在程序控制电路检测到因转矩变换器2输出轴的转速小于其输入轴(内燃发动机1的输出轴)转速的状态而产生滑差时,程序控制电路按电动机控制电动机-发电机5,将车辆置于辅助加速模式.在多级变速器3加档而车辆被内燃发动机1加速时往往会产生这一方向的滑差。在此情况下,按照本发明的混合动力车仍然靠电力加速,因此,车辆的操作被控制在减少液压转矩变换器2内产生的滑差的方向上。当液压转矩变换器2的滑差变小到一个预定值时,在变速器控制电路32的控制下锁定液压转矩变换器2,并且转矩变换器2的输入和输出轴彼此间机械连接。在此时间点暂停辅助加速模式。
若是在多级变速器3的换档过程中因转矩变换器2输出轴的转速大于其输入轴(内燃发动机1的输出轴)转速的状态而产生滑差,就控制电动机-发电机5按照发电机来操作。因此,车辆就进入再生发电制动模式,在此模式中,执行电气制动也就是发电,由此产生的电能用来对蓄电池7重新充电。这样车辆就会减速,使得转矩变换器2中的滑差变小。当滑差变小到一个预定值时,在变速器控制电路32的控制下执行锁定,使转矩变换器2的输入和输出轴彼此间机械连接。在执行锁定之后由变速器控制电路执行的控制类似于混合动力车的普通控制。
图2是用来解释这种操作的控制流程图,能够体现根据本发明的混合动力车的特征。这种混合动力车在车辆通过液压转矩变换器2加速或减速以及在转矩变换器2中产生滑差的操作时间段中的操作以外的其它操作与普通的混合动力车的操作相同。
按照这种控制方式,电动机-发电机5在转矩变换器2中产生滑差的时间段发出辅助动力或辅助制动力。由于车辆因辅助动力或辅助制动力而加速或减速,达到转矩变换器2锁定的时间周期被缩短。另外,由内燃发动机1产生的驱动力或在转矩变换器2中产生滑差的时间段内因内燃发动机1的发动机制动所消耗的制动力会相应地变小。因此,通过转矩变换器2传送的动能就变小,从而有可能减少转矩变换器2的发热也就是转矩变换器2的能耗。
按照本发明,有可能提供这样一种混合动力车,在其动力系统中具有一个转矩变换器,并且能减少转矩变换器的能耗。按照本发明,有可能改善混合动力车的驾驶性能。按照本发明,还有可能提供一种混合动力车,它装备有被驾驶员公认是可靠的变速器系统,并具有驾驶员所熟悉的驾驶性能。
