Description

混合动力电动车辆中的双步换挡
技术领域
本发明总体上涉及具有发动机、电动机械、及多级动力换挡变速器的混合动力电动车辆的传动系。具体地，本发明涉及控制变速器中的双步换挡。
背景技术
动力换挡变速器是利用两个用来在正向驱动和反向驱动中产生多个传动比的输入离合器的齿轮机构。动力换挡变速器使用同步的离合器-离合器(clutch-to-clutch)换挡连续地传递动力。
变速器包括在变速器输入和变速器输出之间的双中间轴(layshaft)配置中设置的传动装置。一个输入离合器在输入和关联于偶数挡位的第一中间轴之间传递转矩；另一个输入离合器在变速器输入和关联于奇数挡位的第二中间轴之间传递转矩。通过交替地接合第一输入离合器并以当前挡位运行，分离第二输入离合器，准备以目标挡位运行的变速器中的动力路径，分离第一离合器，接合第二离合器，准备以下一个挡位运行的变速器中的另一个动力路径，变速器产生传动比变化。
在传动系包括动力换挡变速器的混合动力电动车辆(HEV)中，动力由包括发动机、两个电动机械：曲轴集成式起动机/发电机(CISG)及电动后轴驱动(ERAD)的多个动力源供应。
CISG可以位于发动机和变速器输入之间的驱动路径中，具有常规交流发电机和起动机的功能，提供转矩助力。
ERAD与变速器输出连接并提供转矩到后传动系用于只电(electric-only)驱动和动力推进。在制动车轮时ERAD通过后传动系还提供车辆动能的再生回收。
在两个偶数挡位或在两个奇数挡位之间的换挡称为“双步换挡”。当在相同的中间轴上的挡位之间执行双步换挡时，动力换挡变速器可以在变速器输入处的动力中产生短暂、急剧的减少，有时称为“转矩空洞(torque holes)”。车辆乘员察觉转矩空洞为瞬时的粗劣换挡。
当对动力换挡变速器执行双步换挡时，在工业中具有减少或消除转矩空洞的技术的需要。
发明内容
在双步换挡期间该控制方法使用ERAD马达向车轮提供转矩，从而提供仅包括单个离合器完成双步换挡的方法。该方法明显改进了双步换挡事件时间。
该控制系统及方法消除了转矩空洞，提供正转矩并提供在现有自动变速器中执行换挡的感觉。
该控制明显缩短了在重大驾驶员要求工况下执行降挡的时间，改进了改变主意(change-of-mind)换挡中的响应性，即当车辆驾驶员在踩加速器踏板和松开加速器踏板之间改变时。
由于输入离合器和同步装置在重大驾驶员要求工况下很少使用，在该控制下的传动系操作使输入离合器和同步装置具有加强的耐久性。
若一个输入离合器或该输入离合器的中间轴损坏，该控制方法可以用来执行相同的换挡，然而，在现有的传动系中受到变速器操作的性能约束限于单个挡位。
若车辆驾驶员“改变主意”并松开节气门，改变主意换挡事件发生更快。当松开发生时，改变主意换挡控制策略返回到第五挡位，将再次为相同的轴换挡事件。在现有的车辆中这要求附加的步骤，因为动力流传递到偶数轴，而需要另一个传递返回到奇数轴。
在包括发动机，具有输入、当前挡位、输入离合器、目标挡位、及用于驱动负载的输出的变速器，及驱动负载的电动机械的车辆的传动系中，执行从当前挡位换挡到目标挡位的方法包括以下步骤：开启输入离合器，释放在当前挡位和输出之间的驱动连接，在目标挡位和输出之间产生驱动连接，使用电动机械在负载上产生转矩，闭合输入离合器，及减少电动机械产生的转矩。

具体实施方式
如图1和图2所示，HEV传动系12包括发动机14，如柴油发动机或汽油发动机；变速器16，如双输入离合器动力换挡变速器或没有转矩变换器的另一个多级变速器；第一电动机械18，如可驱动地连接到变速器输入20的CISG；及第二电动机械22，如可驱动地连接到变速器输出24和后轴25的电动马达或ERAD。
ERAD 22位于车轴25的附近且以电动驱动操作模式或混合动力驱动操作模式向轴25提供推进能力。ERAD 22的动力输出通过ERAD传动装置和最终传动单元30，如轮间差动机构驱动车轮26、27。类似地，变速器输出24可以通过包括轮间差动机构的驱动单元36可驱动地连接到第二组车轮34、35。
或者，在第二实施例中，变速器输出24连接到前轮34、35，但不连接到后轮26、27，在该例子中ERAD 22驱动后轮，但不驱动前轮。图6示出第二实施例。
在第三实施例中，变速器输出24连接到前轮34、35，但不连接到后轮26、27，ERAD除去，第三电动机械XX，如电动前轴驱动(EFAD)可驱动地连接到前轮34、35。图7示出第三实施例。
在发动机起动过程期间CISG 18用来起动转动发动机14。当CISG由发动机或由ERAD驱动时，或CISG或ERAD，或CISG和ERAD两者由车辆的车轮驱动时，CISG 18和ERAD 22用来使电池28再充电。
图2示出变速器16的细节，包括第一输入离合器40，第一输入离合器40选择性地交替连接变速器16的输入20到关联于第一中间轴44的偶数挡位46，及第二输入离合器45，第二输入离合器45选择性地交替连接输入20到关联于第二中间轴49的奇数挡位47。
电子变速器控制模块(TCM)50通过发送到驱动输入离合器的电磁驱动伺服系统的指令信号控制输入离合器40、45。电子发动机控制模块(ECM)52控制发动机14的操作。TCM 50和ECM 52每个包括可存取到电子存储器并包含以计算机代码表示，可以在频率间隔中重复执行的控制算法的微处理器。
轴44支撑各自通过轴颈安装在轴44上的小齿轮60、62、64和固定到轴44上的连接器66、68。小齿轮60、62、64分别关联于第二、第四和第六挡位。连接器66包括轴套70，轴套70可以向左移动以接合小齿轮60并可驱动地连接小齿轮60到轴44。连接器68包括轴套72，轴套72可以向左移动以接合小齿轮62并可驱动地连接小齿轮62到轴44，且可以向右移动以接合小齿轮64并可驱动地连接小齿轮64到轴44。
轴49支撑各自通过轴颈安装在轴49上的小齿轮74、76、78和固定到轴49上的连接器80、82。小齿轮74、76、78分别关联于第一、第三和第五挡位。连接器80包括轴套84，轴套84可以向左移动以接合小齿轮74并可驱动地连接小齿轮74到轴49。连接器82包括轴套86，轴套86可以向左移动以接合小齿轮76并可驱动地连接小齿轮76到轴49，且可以向右移动以接合小齿轮78并可驱动地连接小齿轮78到轴49。
输出24支撑各自固定到轴24的齿轮88、90、92。齿轮88与小齿轮60和小齿轮74啮合。齿轮90与小齿轮62和小齿轮76啮合。齿轮92与小齿轮64和小齿轮78啮合。
连接器66、68、80、82可以是同步装置，或牙嵌式离合器(dog clutch)或这些装置的组合。
图3示出在位于使用ERAD 22参与换挡的传动系12中的动力换挡变速器16中执行和控制从第五挡位到第三挡位的开机的，双步换挡的步骤。注意不要求第四挡位的接合和两个输入离合器的接合/分离。
当变速器16以第五挡位操作时，在步骤100，连接器82的轴套86与小齿轮78接合，输入离合器40完全地分离或开启，输入离合器45完全地接合。因为变速器16这样设置，在步骤102，在第五挡位中，连接器86通过离合器45和轴49连接小齿轮78到输入20，小齿轮78通过齿轮92、输出24、ERAD 22及驱动单元30可驱动地连接到驱动车辆或负载的车轮26、27，或连接到车轮34、35或连接到车轮26、27、34及35。
在步骤104通过开启离合器45开始从第五挡位到第三挡位的变速器16的双步降挡。图4B示出首先在步骤108减少输入离合器45的转矩能力，然后沿着斜坡110到量值112进一步减少，量值112保持恒定一段期间，然后沿着第二斜坡114减少到零转矩能力。
在步骤116，连接器82的轴套86向左移动到离开与小齿轮78接合的分离的位置并停止以第五挡位操作，离合器80的轴套84向左移动以与小齿轮74接合，从而将变速器16设置为以第三挡位操作。
在步骤118，ERAD 22开始产生输出转矩。图4B示出ERAD 22的转矩输出首先在121期间中沿着斜坡120增加到量值122，量值122保持恒定一段期间123，然后在期间125中沿着斜坡124减少到零转矩能力。在期间121中转矩能力沿着斜坡120增加与斜坡114同时发生。在图4B中所示的转矩交联确保转矩中的平滑切换。
在步骤126，当ERAD转矩减少到零转矩且输入离合器的转矩能力沿着上升128增加时，发生从ERAD 22到输入离合器45的转矩的传递。
在步骤130，输入离合器45闭合以便其转矩能力沿着上升128快速增加到完全接合的转矩能力132，维持完全接合的转矩能力132并保持恒定。
图4C示出当输入离合器45减少其转矩能力时由输出24传递的转矩的量值在134仅略微地降低。由输出24传递的转矩的量值在从第五挡位到第三挡位的降挡切换操作期间为恒定的量值136。
在图4A-图4C中，垂线138表示第五挡位操作结束的时间中的点，垂线140表示第三挡位操作开始的时间中的点。当发生从第五挡位到第三挡位的切换时在降挡期间ERAD 22产生的输出转矩为最大值。
图4A示出由于从第五挡位142到第三挡位144的变化，输入49的转速的变化，和发动机转速146的变化。
输入离合器40、45不能同时完全接合，或导致的关联将损坏变速器16。当换挡发生时，输入离合器40、45必须平滑地、同步地在轴44、49之间传递转矩。没有从一个轴到另一个轴的同步的转矩的传递，将导致在换挡期间到车轮的转矩损耗。
控制来自ERAD 22的转矩可以在换挡之前准备，因为安排的换挡是已知的。ERAD22是用于在从第五挡位到第三挡位的切换期间向车轮提供转矩的快速转矩装置。随着离合器45的再接合ERAD转矩停止斜升(ramp off)。使用ERAD充填转矩绕过中间换挡进入第四挡位导致明显地更快双步换挡。
虽然参考动力换挡变速器描述本发明，但本发明可以应用到任何现有的手动变速器、自动换挡手动变速器、或在位于发动机和变速器输入之间的动力路径中没有转矩变换器的自动变速器。动力换挡变速器16的输入离合器40、45可以是液压驱动的湿式离合器，或可以是电动或电磁驱动的干式离合器。
图5示意性地示出图1的传动系，其中变速器输出24通过差动机构36可驱动地连接到前轮34、35，及连接到ERAD 22两者，ERAD 22可驱动地通过差动机构30连接到后轮26、27。在发动机14的输出60和CISG 18的输出产生的转矩输送到150用于传递到变速器输入20。
图6示意性地示出传动系的第二实施例，其中变速器输出24可驱动地通过差动机构36连接以仅驱动前轮34、35。在发动机14的输出60和CISG 18的输出产生的转矩输送到150用于传递到变速器输入20。ERAD 22驱动后轮26、27。
图7示意性地示出传动系的第三实施例，其中变速器输出24可驱动地连接到EFAD152，EFAD 152的输出154通过差动机构36驱动前轮34、35。在发动机14的输出60和CISG 18的输出产生的转矩输送到150用于传递到变速器输入20。
虽然参考第五挡位到第三挡位的开机的降挡描述该方法，该控制方法和系统可以应用到任何双步换挡中。
根据专利法的规定，已描述了优选实施例。然而，应理解除了具体所述和所示的实施例外还可以实施替代的实施例。
