Abstract

一种控制车辆再生制动的方法包括：如果变矩器离合器为锁定该状态则减小再生制动，以使再生制动扭矩在变矩器离合器由于车辆速度达到参考速度而打开以前达到零；如果变矩器离合器预定要打开，则减小再生制动，以使再生制动扭矩可在变矩器离合器由于车辆速度达到参考速度而打开以前达到零；以及运用车轮制动来制动车辆。

Description

再生制动和变矩器控制
技术领域
本发明总体上涉及一种用于混合动力电动车中控制再生制动事件的方法，其中混合控制与变矩器控制相配合。
背景技术
为了实现混合动力电动车燃油经济性的最大化，通过用电动机在制动事件过程中的再生制动来节约能源成为该***的主要组成部分。高电压电池可以在车辆减速时通过再生制动来充电。另一方面，为保持车辆安全，当再生制动其本身不能够满足驾驶员的需求时，传统的摩擦制动也会被使用。在再生制动变得不可用或效率低下之前的低速下；再生制动扭矩应该逐渐下降至零，并且传统摩擦制动扭矩应该逐渐增大至驾驶员的需求，以促进制动扭矩平稳地过渡。这个过程被称为再生制动扭矩融合。因此，能够以合意的车辆驾驶性能、燃料效率以及车辆安全性满足驾驶员的制动需求。
在模块式的混合动力电动车中，有级式变速器和变矩器位于电动机和连接有车轮的驱动桥之间。在再生制动的过程中，车辆的动能通过变速器和变矩器来旋转电机为高电压电池充电。为了将车辆动能充分地传递至电动机，变矩器离合器必须锁定。如果变矩器必须打开，车辆动能将会传递得更少。在这种情况下，再生制动扭矩融合应该在变矩器打开前完成以防止电动机停转。
发明内容
一种控制车辆再生制动的方法包括：如果变矩器离合器为锁定，则减小再生制动，以使再生制动扭矩在变矩器离合器由于车辆速度达到参考速度而打开以前达到零；如果变矩器离合器预定要打开，则减小再生制动，以使再生制动扭矩在变矩器离合器由于车辆速度达到参考速度而打开以前达到零；以及运用车轮制动来制动车辆。
燃油经济性，驾驶性能以及车辆安全性是混合动力电动车控制的主要关注问题。变矩器与再生制动***控制之间的配合提供了动态的、即时的再生制动融合(blend-out)控制，这有益于燃油经济性，驾驶性能以及车辆安全性。首先，变矩器离合器打开状态的预测和通知允许再生制动***在变矩器离合器打开之前充分利用时机获得尽可能多的动能。其次，斜坡曲线(ramp curve)提供了平稳的扭矩过渡。
优选实施例的适用范围通过以下详尽的说明书、权利要求以及附图会变得更明显。需要了解的是，说明书和具体实施例虽然显示了发明的较佳实施方案，但其仅以例示方式给出。所述方案的各类变动和修订将对所属领域的技术人员来说变得明显。
附图说明
通过参照以下描述并结合附图，本发明将会更容易理解，其中：
图1是显示用于机动车辆的模块化混合动力***的示意图；
图2A和2B包括了一种在与变矩器离合器运行的配合中用于控制再生制动扭矩融合的算法的流程图；以及
图3包括了一些图表，该图表说明了与变矩器控制时间图相配合的再生制动扭矩融合控制。
具体实施方式
首先参考图1，并联混合动力***10包含内燃发动机12，发动机断开离合器14，电机或发动机/发电机16，变速箱液压泵18，变矩器20，变矩器锁止离合器22，传动装置24，最终传动装置26，轴28、29以及从动轮30。由低电压电池34驱动的低电压启动器32在启动发动机12和进行持续燃烧时曲柄启动发动机。高电压电池36为发动机/发电机16提供电力。
变矩器20为液压耦合器，其在泵轮(impeller)与涡轮之间产生液动力驱动连接，其中泵轮当离合器14闭合时驱动地与发动机12相连接，而涡轮驱动地与从动轮30相连接。
变矩器锁止离合器22交替地打开和闭合变矩器涡轮与轴38之间的驱动连接。
装备有该动力***10的车辆能够产生电驱动和混合电驱动，并且不仅能够通过再生制动给电池36充电，即在制动事件过程中将车辆动能回收并转化为可以保存在电池36中的电能，还能运用发动机为电池36充电。
混合动力电动车中的燃料经济效益主要是由其实行再生制动的能力产生的。在动力***10中，电动机16通过变矩器20、传动装置24以及最终传动装置26与车轮耦合。如果变矩器离合器22滑动，则变矩器20通过液压路径与机械路径相结合来传递扭矩。如果变矩器离合器22完全打开，则扭矩仅能通过液压路径来传递。如果变矩器离合器22完全锁定，则扭矩仅能通过机械路径来传递。
在再生制动过程中，扭矩由车轮30被传递至电机16。如果离合器22是打开的，则变矩器反向传递扭矩的能力是十分有限的。为了运用再生制动回收最多的动能，变矩器离合器22应该在车辆减速时保持锁定状态。
然而，变矩器离合器22由于各种各样的原因必须打开。当泵轮转速低时，离合器22必须打开以便使电动机和/发动机12不会停止。当离合器22打开时，液压路径作为耦合器来将扭矩平稳地传递给车轮30。
所述控制协调再生制动***控制和变矩器控制。在再生制动运行过程中，车辆控制***协调制动扭矩中再生制动部分和制动扭矩中传统摩擦部分，以确保整体制动扭矩满足驾驶员的制动需求和车辆减速的性能。如果由于一些原因，再生制动扭矩必须减小，则必须加以控制以便使再生制动扭矩平稳地减小以及与此同时传统摩擦制动扭矩能够填补其空缺。该控制过程称为再生扭矩融合。在维持不打折扣的整体的车辆减速性能和安全性能时，再生扭矩融合控制关于制动扭矩的来源和两种来源对制动扭矩的贡献度变化应该对车辆再生扭矩融合操作者来说是明显的。
在再生扭矩融合控制过程中，制动扭矩的再生部分相对于总的制动扭矩减小。这种减小称为再生扭矩倾斜下降。
图2A和图2B的流程图阐明了用于控制与变矩器离合器22操作相配合的再生制动扭矩融合的控制算法40的各个步骤。控制算法40被分为3个阶段。在阶段1中，变矩器控制预测是否要在一段时间内打开变矩器。如果变矩器即将打开，则控制预测变矩器打开时车辆的速度。在第2阶段，变矩器控制命令变矩器离合器22打开，并继续监控离合器22在任何正常和紧急情况下变矩器打开时的状态。在第3阶段，控制确定并报告变矩器实际打开状态。
在再生制动运行过程中，车辆控制***协调制动扭矩中的再生制动部分与制动扭矩中的传统摩擦部分，以确保整体制动扭矩满足驾驶员的制动需求和车辆的减速性能。如果由于一些原因，再生制动扭矩必须减小，则必须加以控制以便使再生制动扭矩平稳地减小以及与此同时传统摩擦制动扭矩能够填补其空缺。该控制过程称为再生制动扭矩融合。成功的再生制动扭矩融合控制在制动扭矩来源和贡献度变化方面对于车辆驾驶员来说应该是明显的，以及产生不打折扣的整体的车辆减速性能和安全性能。
在再生制动融合控制过程中，制动扭矩中的再生部分减小了其在整体制动扭矩中的贡献度。这种制动扭矩中的再生制动部分的减小称为再生制动扭矩倾斜下降。
再生制动融合控制要在所有三个阶段与变矩器打开控制保持一致。在每个阶段的再生制动扭矩融合是通过被设计为单调递减的倾斜率(rampratio)来控制的，拥有不同的可校准的持续时间，直到融合完成。在第1阶段，融合持续时间将与用于变矩器的打开预测的时间相对应。在第2阶段，持续时间将与变矩器在常规或紧急打开事件中打开运行的时间相对应。在第3阶段，再生制动扭矩将由于变矩器离合器打开而立即减小至零。为确保平稳的扭矩过渡，在第1阶段和第2阶段中，倾斜率变化率是基于完成事件的预期时间和目标倾斜率与变矩器上一个相位变化时的倾斜率的差来计算的。在步骤42，车辆正常运行，没有再生制动，变矩器离合器22完全锁定。
在步骤44，执行测试以确定再生制动是否发生。如果测试44的结果为逻辑错误，则控制回到步骤42。
如果测试44的结果为逻辑正确，则在步骤46执行测试以确定变矩器离合器22是锁定、正在打开或打开。如果变矩器离合器22为打开状态，则通过设置任何再生制动扭矩请求至零，于步骤48开始第3阶段控制。然后控制前进至步骤50，传统制动扭矩，即由摩擦产生的车轮制动，增大至可以满足整体车辆制动扭矩的需求。
如果测试46得出变矩器离合器22为锁定，在步骤52基于适当的一个或多个速率传感器的输出结果来确定当前车辆速度和车辆减速速率。
在步骤54，将确定预测车辆速度，该速度是基于可校正的预测时间内的当前车辆速度和车辆减速速率而确定的。
在步骤56，执行测试以确定预测车辆速度是否低于参照变矩器解锁速度。如果测试56的结果为否，在步骤58中确定车辆在变矩器离合器22锁定状态下运行后，控制回到步骤42。
如果测试56的结果为是，在步骤60，因变矩器离合器22在预测时段即将打开而开始第1阶段的控制。
在步骤62，再生制动扭矩渐变倾斜下降速率根据预测时间的长度而确定。
在步骤64，再生制动扭矩请求基于倾斜下降速率而减小，直至再生制动扭矩请求为零。然后控制前进至步骤50。
如果测试46得出变矩器离合器22为正在打开，在步骤66执行测试以确定变矩器离合器22是在正常事件还是在紧急事件下打开的。
如果测试66得出结果表明是紧急事件导致了变矩器离合器22的打开，则在步骤68由于变矩器离合器22在紧急情况下的打开而开始第2a阶段的控制。在步骤70，再生制动扭矩倾斜下降速率基于紧急情况打开的时间长度建立。
在步骤72，再生制动扭矩请求基于倾斜下降速率减小，直至再生制动扭矩请求将至零。然后控制前进至步骤50。
但是如果测试66得出结果表明是正常事件导致了变矩器离合器22的打开，则在步骤74由于变矩器离合器22在正常情况下的打开而开始第2b阶段。
在步骤76，再生制动扭矩倾斜下降速率基于正常情况打开的时间长度而建立的。
在步骤78，再生制动扭矩请求基于倾斜下降速率减小，直至再生制动扭矩请求将至零。然后控制前进至步骤50。
图3说明了MHT(模块化混合动力传动***)混合动力电动车典型的再生制动运行事件。当变矩器锁定100且车辆驾驶员通过踩制动踏板102发起制动请求时，再生制动运行。负的总制动扭矩，包括再生制动扭矩和传统摩擦制动扭矩，满足驾驶员制动扭矩的需求。再生制动扭矩在电动机16中用于为高压电池36补充电力。
在再生制动过程中，当车辆速度以特定减速速率104减小时，车辆减速。基于车辆速度以及车辆减速速率，在可校正的预测时间窗口108内，可计算出预测车辆速率。当该预测车辆速率跨越到低于变矩器解锁速率临界值110时，变矩器离合器22即将在预测期108内打开。然后，负的再生制动扭矩112在预测期间108内并基于预测期间108倾斜下降114。
当实际车辆速度104在116跨越到低于变矩器解锁速率临界值110时，变矩器离合器22处于打开阶段118。如果还没有倾斜下降至零，再生制动扭矩将基于打开时间继续倾斜下降。
变矩器离合器22实际打开120时，如果还没有倾斜下降至零，再生制动扭矩会立即在122设置为零。这样可以确保当变矩器离合器22打开时没有再生制动。
与此同时，贯穿整个再生制动事件，控制传统摩擦制动扭矩124以填补由于再生制动扭矩变化造成的任何空缺。从而使总体为负的制动扭矩126总是满足驾驶员对制动扭矩的需求。
在128、130和132的再生制动事件过程中，会产生齿轮比转变。
按照专利法相关规定，优选方案已经说明。然而，需要注意的是，与具体说明和描述不同的可选方案也可以实施。
