Description

提升电动车辆模式中驱动性能的混合动力车辆系统
相关技术的交叉引用
本申请要求了2011年11月10日在韩国知识产权局申请的申请号10-2011-0117203的韩国专利申请的优先权及其利益，其全部内容作为参考合并在此。
技术领域
本发明涉及混合动力车辆的系统，相比于传统混合动力车辆，其提升了在电动车辆模式中的驱动性能。
背景技术
混合动力车辆为使用两种或多种不同的动力源推动车辆的车辆。该术语通常是指混合动力电动车辆(HEV)，其结合了一个内燃机与一个或多个由电池提供能量的电动机。然而，还存在混合动力车辆的可替换形式，如混合动力燃料电池车辆。
在过去的几年内，由于混合动力车辆的高燃油效率以及对环境的低影响，它们已经变得越来越普及。
通常混合动力车辆可以分为两种不同种类，并联式混合动力以及串联式混合动力。在并联式混合动力中，安装一个或多个电动机与一个内燃机，以使得它们可以单独或一起为车辆提供动力。然而，在串联式混合动力中，通过不与发动机机械连接的电动机驱动车辆。相反，发动机被配置为在供应于发动机的电池组能量充电或者不充电时用以运行发电机。
然而，最近制造商已经开始引进另一种被称为插电式混合动力车辆(PHEV)的混合动力车辆。在PHEV中，相比于传统混合动力电池增加了电池容量，并且经由市电为电池充电，而不是通过再生制动或发电机。因此，这些车辆使驾驶员可以在行驶短距离时仅使用电能操作车辆(即，EV模式)，而在电池没电了的时候可以用传统HEV模式操作车辆。
因此，可以根据驾驶员行驶远近，选择通过同时使用内燃机与电动机或者使用内燃机与电动机中之一来驱动PHEV。在这些类型的混合动力车辆中，要将容易用电充电、并且通常具有较大容量的高压电池安装于插电式混合动力车辆中的某个地方。
因为通常认为混合动力车辆能实现与传统内燃机相似的功能，而且消费者还期望在电动车辆模式中提升驱动性能，因此其电动机的输出容量相比于传统混合动力车辆需要增大。
为了增加电动机的输出容量，材料成本的增加通常是不可避免的，并且总的制造成本也因此增加。
特别地，因为在电动车辆模式中释放离合器1，如图1所示，第一电动机/发电机MG1不能用作类似于传统混合动力系统中的动力源以提供驱动力。进一步，因为第二电机/发电机MG2负责提供用于驱动车辆所输出的全部驱动力，并且第一电机/发电机MG1仅用于发动机启动并在EV模式中产生电力。因此，通过在EV模式中操作的第二电机/发电机MG2不能保证足够的驱动性能。
在本背景技术部分公开的以上信息仅用于提升对本发明的背景技术的理解，因此其可能包含不构成本国的本领域技术人员已知的现有技术的信息。
发明内容
本发明努力提供一种用于混合动力车辆的系统，其具有提升在电动车辆模式(EV模式)中的驱动性能的优势，同时降低制造成本。
根据本发明的典型实施例的用于混合动力车辆的系统包括发动机、变速器以及电池。该系统还可以包括配置成将发动机与变速器连接、并且具有第一部与第二部的第一离合器；配置成连接于第一部、并且直接连接于变速器的第一电动机/发电机；配置成连接于第二部的第二电机/发电机；以及配置成将第二电机/发电机与变速器连接的第二离合器。特别地，第一部与第二部可以是独立操作的离合器。
在一个或多个典型实施例中，当车辆在EV模式下进行操作时，可以释放第一部与第二部，并且可以接合第二离合器，以操作第一与第二电机/发电机驱动车辆。
在一个或多个典型实施例中，在车辆在EV模式下进行操作时，可以释放第一部以通过第一电机/发电机驱动车辆，可以接合第二部，并且释放第二离合器，以当启动发动机时，发动机由第二电机/发电机启动。
在一个或多个典型实施例中，当车辆在混合动力模式下进行操作时，可以接合第一部，并且可以释放第二部与第二离合器，以通过来自发动机与第一电机/发电机的动力驱动车辆。
在一个或多个典型实施例中，当车辆在混合动力模式下进行操作时，可以接合第一部，可以释放第二部，并且可以接合第二离合器，以通过来自发动机以及第一与第二电机/发电机的动力驱动车辆。而且，当需要再生制动时，可以释放第一部，以使第一电机/发电机产生电力。
在一个或多个典型实施例中，当还需要再生制动时，可以释放第一部，以使第一电动机/发电机产生电力，并且可以接合第二离合器，以使第二电机/发电机产生电力。

在以下的详细说明中，已经简单地通过示例，仅示出并且说明了本发明的特定典型实施例。如本领域技术人员应该认识到的是，在不脱离本发明的精神与范围的情况下，可以以多种不同的方式修改所描述的实施例。因此，附图与说明被认为在本质上是示例性的，但不是限制性的。在整个说明书中，相同的参考数字指定相同的元件。

将在下文中参照附图详细描述本发明的典型实施例。
图2为根据本发明的一个典型实施例的用于混合动力车辆的系统的示意图。如图2中所示，根据本发明的一个典型实施例的用于混合动力车辆的系统100包括发动机200，变速器300，以及电池400。此外，用于混合动力车辆的系统100进一步包括将发动机200与变速器300相连接，并且具有第一部510与第二部520的第一离合器500；连接于第一部510，并且直接连接于变速器300的第一电机/发电机600；连接于第二部520的第二电机/发电机700；以及选择性地将第一电机/发电机700与变速器300相连接的第二离合器800。此处，第一部510与第二部520为第一离合器500的组成元件，并且为可以独立操作的离合器。
根据本发明的典型实施例的用于混合动力车辆的系统100尤其可以用于插电式混合动力车辆(PHEV)。插电式混合动力车辆(PHEV)具有与传统混合动力车辆的结构相似的结构，但在插电式混合动力车辆中安装有大容量的高压电池。高压电池400可以通过电力充电。因为需要混合动力车辆提升电动车辆模式下的驱动性能，所以与传统混合动力车辆相比，应当增加电动机的输出容量。
第一离合器500将发动机200与变速器300选择性地相连接，以使得将发动机200的动力传送至变速器300或不传送至变速器300。而且，根据本发明的一个典型实施例的第一离合器500，如图2所示，分为第一部510与第二部520。第一部510连接于第一电机/发电机600，以便将发动机200选择性地连接于第一电机/发电机600。
第一电机/发电机600直接连接于变速器300，以使得将第一电机/发电机的动力直接传送至变速器300。当释放第一部510时，第一电机/发电机600接收来自电池400的动力，并且通过再生制动产生电力，为电池400充电。
同时，第一离合器500的第二部520连接于第二电机/发电机700。此外，将第二电机/发电机700连接于另外设置于变速器300的一个从动轴处的第二离合器800，并且当接合第二离合器800时，将第二电机/发电机700的动力通过第二离合器800传送至变速器300。
当接合第一部510、并且释放第二离合器800时，第二电机/发电机700也接收来自电池400的动力，并且经由发动机200的驱动转矩产生电力，为电池400充电。
根据本发明一个典型实施例的用于混合动力车辆的系统100同时使用第一电机/发电机600与第二电机/发电机700作为在EV模式下驱动车辆的动力源，其经由第二离合器800将来自第二电机/发电机700的动力传送至变速器300。
也就是说，不像如图1中所示的传统技术，其仅使用第一电机/发电机MG1通过例如皮带直接连接于发动机，以启动发动机或产生电力，本发明的示例性实施例在车辆处于EV模式时，能够同时经由第一与第二电机/发电机将驱动输出供给至变速器TM。
也就是说，在根据本发明的一个典型实施例的用于混合动力车辆的系统100的情况中，如图2中所示，通过将第二离合器800插入第二电机/发电机700与变速器300之间而将第二电机/发电机700连接于变速器300，从而可以将第二电机/发电机700的动力传送至变速器300。因此，可以移除传统技术中的连接发动机与第一电机/发电机MG1的皮带。
根据本发明的一个典型实施例，因为第一电机/发电机600与第二电机/发电机700可以同时将动力传送至变速器300，所以相比于传统技术可以提升EV模式中的驱动性能。
此外，根据本发明的一个典型实施例，因为通过如图2所示的第二部520连接第二电机/发电机700与发动机200，所以可以通过驱动第二电机/发电机700启动发动机200。
在下文中，将详细描述根据本发明的一个典型实施例的用于混合动力车辆的系统100在每种驱动模式下的操作。
当车辆在电动车辆(EV)模式下进行操作时，系统释放第一离合器500的第一部510与第二部520，并且接合第二离合器800。通过释放第一离合器500从而使发动机200的驱动转矩不输送至变速器300，并且因此将第一电机/发电机600与第二电机/发电机700的驱动转矩输送至变速器300。因为由两个电机/发电机600与700供给驱动转矩，所以可以提升电动车辆模式的驱动性能。
当车辆在电动车辆(EV)模式下进行操作时，要重新启动发动机，系统释放第一部510与第二离合器800，并且接合第二部520。
通过释放第一部510而将发动机200从变速器300分离，并且仅将第一电机/发电机600的驱动转矩输送至变速器300。此外，通过释放第二离合器800而将第二电机/发电机700从变速器300分离，并且通过接合第二部520而连接第二电机/发电机700与发动机200。因此，通过来自第二电机/发电机700的动力可以启动发动机200。
当车辆在混合动力模式下进行操作时，系统接合第一部510，并且释放第二部520与第二离合器800。在这种情况下，由于第一部510的接合，将发动机200的驱动转矩输送至变速器300，并且还将第一电机/发电机600的驱动转矩输送至变速器300，从而同时从发动机200与第一电机/发电机600将动力提供至变速器。此时，可以释放第二部520与第二离合器800。因此，车辆在HEV模式下进行操作的过程中，不将来自第二电机/发电机700的驱动转矩输送至变速器300。
同时，当处于混合动力模式时，系统可以接合第一部510，释放第二部520，并且接合第二离合器800，以使得由于第一部510的接合，将来自发动机200的驱动转矩传送至变速器300，由于第二离合器800的接合，将来自第二电机/发电机700的驱动转矩传送至变速器300，并且还将第一电机/发电机600的驱动转矩也传送至变速器300。因此，在以上的方案中，混合动力车辆由发动机200、第一电机/发电机600以及第二电机/发电机700驱动。
当车辆制动时，系统释放第一部510，以从变速器300分离发动机200，并且第一电机/发电机600通过再生制动产生电力。电池400由第一电机/发电机600产生的电力充电。
当再生制动时，为了获得更大的再生力，系统释放第一部510以使第一电机/发电机600产生电力，并且接合第二离合器800以使第二电机/发电机700也产生电力。以上描述了第一电机/发电机600通过再生制动产生电力。
此外，通过接合第二离合器800以连接第二电机/发电机700与变速器300。因此，将由再生制动得到的动能通过变速器300输送至第二电机/发电机700。通过使用动能，第二电机/发电机700产生电力，并且通过由第二电机/发电机700产生的电力为电池400充电。因此，因为通过同时使用第一电机/发电机600与第二电机/发电机700为电池400充电，所以可以获得更大的再生力。
根据本发明的典型实施例的有利之处在于，因为第一电机/发电机与第二电机/发电机可以将驱动转矩传送至变速器，所以可以提升电动车辆模式下的驱动性能。而且，根据本发明的典型实施例，因为不需要额外的开发成本与材料成本来增加电动机的输出容量，所以还可以降低制造成本。
尽管已经结合目前认为实用的典型实施例来描述本发明，但应该理解的是，本发明并不限于所公开的实施例，相反，其旨在覆盖包括在所附权利要求的精神与范围内的各种改装以及等同装置。
