Abstract
一种混合动力系***包括分别连接至第一驱动轴和第二驱动轴的发动机和电机,其中电机与发动机分离。***包括电池组和控制器。控制器具有滑移积分器,其具有用于给定的一个驱动轴的对应积分器值。积分器值指示在所校准持续时间或窗口上的驱动轮滑移的累加量。积分器值响应于轴扭矩和牵引控制状态信号而改变。积分器值加在一起以得出积分器和。响应于积分器和超过所校准积分器阈值,控制器执行控制动作,包括自动执行天气模式,其中电池组的能量使用被保留用于车辆的牵引控制/推进。
Description
引言
混合动力系使用多个扭矩生成装置来生成扭矩并将扭矩传递到耦合负载。扭矩生成装置可以包括内燃机和一个或多个电力牵引电机。发动机扭矩可以用于在一些混合动力系中发电并且主动地对车载推进电池组充电。电池组为电力牵引电机提供能量,电力牵引电机又耦合至一个或多个驱动轴或驱动轮。在一些动力系配置中,牵引电机可以与发动机分离,在这种情况下,不能实现电池组的发动机充电。这种配置中的电池组通过驱动轮和道路表面之间的接触而被再充电,其中牵引电机在负电机扭矩期间作为发电机操作。
发明内容
本文公开了一种混合动力系***,其具有高压推进电池组、内燃机和电机。如本文所用,术语“高压”是指超过辅助电压电平的电压,对于实例性汽车应用,其标称值为12-15伏。发动机和电机分别耦合至不同的驱动轴,例如后驱动轴和前驱动轴。另外,电机和发动机彼此分离,即,在发动机和电机/电池组之间不存在电力流动路径。因此,不能经由电机实现发动机驱动的电池组的充电。
混合动力系***还包括控制器。每当采用动力系***的车辆在具有低摩擦系数的道路表面上操作时,相对于其它能量需求,控制器优先考虑电池组的功率输出和充电。这种通常称为“低μ”表面的表面可以是冰或雪覆盖的、湿的、油性的或其它光滑的,因此易于引起与道路表面接触的驱动轮的滑移。经由执行体现本文所述方法的指令,控制器实时地自动执行这种电力流动控制。
执行指令使控制器修改控制输入,而不需要操作员这样做的肯定请求。由于发动机与电机分离,因此在没有本方法的情况下,可能难以在延长的正扭矩请求期间保留或节省用于牵引控制/推进目的的电池能量,并且同时采用可用的电机扭矩来补偿发动机的燃料消耗。所公开的方法旨在解决在上述低μ表面上操作时的这种潜在功率消耗和功率分配问题。
根据实例实施例的混合动力系***包括分别连接至第一驱动轴和第二驱动轴的发动机和电机。如上所述,电机与发动机分离。高压推进电池组经由功率逆变器模块(PIM)连接至电机。电池组还可以经由在本文称为辅助功率模块(APM)的DC-DC功率转换器连接至辅助电池。
控制器包括多个滑移积分器,即基于逻辑的信号值累加器,其中给定的滑移积分器和相关联的积分器值分别对应于第一驱动轴和第二驱动轴。积分器值响应于所报告轴扭矩和具有混合动力系***的车辆的牵引控制***的启动状态而改变,其中启用状态在滑移事件期间改变为二进制开启或真状态。控制器添加驱动轴的积分器值以得出积分器和。响应于积分器和(积分器的总值)超过所校准积分器阈值,控制器相对于动力系执行一个或多个对应的控制动作。例如,控制器可以可选地考虑增加滑移严重性的多个不同阈值,然后逐渐执行绑定至超过特定阈值的不同控制动作。控制动作(或多个动作)建立动力系操作模式,其仅从支持牵引控制/推进功能的电池组分配电能,并且可能采取支持这种分配的其它动作。
控制器可以根据所报告轴扭矩和所校准滑移阈值来计算滑移增益值。当轴扭矩小于或等于所校准滑移阈值时,滑移增益值可以是正的。当启动状态信号开启/为真时,即当检测到滑移并且滑移增益值为正时,控制器将滑移积分器值增加滑移增益值的量。相反,当轴扭矩超过所校准滑移阈值时,滑移增益值可以是负的。对于这种情况,将应用滑移增益值来减小滑移积分器的值。
控制动作可以包括仅经由发动机(例如经由交流发电机)临时为辅助功率负载供电,而不使用APM和来自高压电池组的电力。
控制器可以可选地配置为响应于例如风挡玻璃刮水器电机的速度和/或来自环境温度传感器的温度信号而实时调整滑移阈值。
在可选实施例中,第一驱动轴和第二驱动轴可以分别是后驱动轴和前驱动轴。
控制动作可以包括相对于在普通操作模式期间使用的默认水平将电池组的充电状态目标阈值增加至少30%。
控制动作可以包括禁用发动机停止-起动功能,其需要来自高压功率组的功率分配,从而节省用于牵引控制/推进事件的能量。除此之外或作为替代,控制动作可以包括禁用电动“推进增压”功能,其协助来自发动机的扭矩只是为了改善燃料经济性。提升燃料经济性的这种电动增压动作的一个实例是延长主动燃料管理(AFM)操作的电动推进增压的动作。
从以下结合附图对实现本发明的最佳模式的详细描述中,本公开的上述特征和优点以及其它特征和优点将变得显而易见。

本公开易于进行修改和替代形式,其中代表性实施例在附图中以实例的方式示出并在下面详细描述。本公开的发明方面不限于所公开的特定形式。相反,本公开旨在覆盖落入由所附权利要求限定的本公开的范围内的修改、等同物、组合和替代。
具体实施方式
本文描述了本公开的实施例。各种实施例是本公开的实例,鉴于本公开,本领域普通技术人员可以想到其它替换形式的实施例。附图不一定按比例。某些特征部可以夸大或减到最小,以便显示特定部件的细节。因此,本文公开的具体结构和功能细节不应被解释为限制,而是作为用于教导本领域技术人员以各种方式采用本公开的代表性基础。
如本领域普通技术人员还将理解的,参考给定的一个附图示出和描述的特征可以与一个或多个其它附图中示出的特征组合,以便产生未明确示出或描述的实施例。因此,所示特征的组合用作典型应用的代表性实施例。然而,对于特定应用或实施方式,可能需要与本公开的教导一致的特征的各种组合和修改。
参考附图,其中相同的附图标记表示相同的部件,图1中示意性地描绘了车辆10。车辆10包括混合动力系***12,其操作由控制器(C)14实时控制。控制器14的物理位置可以是***12内的任何地方,例如,与具有牵引电机(正扭矩)和发电机(负扭矩)能力的功率逆变器模块(PIM)29和/或电机(ME)20并置。
动力系***12包括多个用于推进的扭矩源。在例如示意地描绘P4型动力系配置的图1的实例实施例中,扭矩源包括内燃机(E)15和电机20。发动机15配置为燃烧汽油、柴油、乙醇或生物燃料以生成发动机扭矩(箭头TE)。当通过高压电池组(BHv)22在高压总线(VHV)上被提供能量时,电机20分别生成扭矩(双向箭头TM),即取决于电机20是否作为电机或发电机操作的分别的正扭矩或负扭矩,其中电池组22电连接至电机20。如上所述,“高压”是指超过12-15伏的电压电平,例如30-300V或更高,这取决于电力牵引电机20的配置。
图1所示的车辆10包括后驱动轴16R和前驱动轴16F,每个后驱动轴16R和前驱动轴16F分别机械耦合至驱动轮18。电机扭矩(双向箭头TM)可以经由图1的示例性实施例中的驱动桥布置21传递到前驱动轴16F,不限于这种配置。混合动力系***12提供全轮驱动能力,其中,在所示的示例性实施例中,发动机15连接至后驱动轴16R并且电机20连接至前驱动轴16F。在其它实施例中,发动机15和电机20的位置可以相反,即,发动机15连接至前驱动轴16F并且电机20连接至后驱动轴16R。替代地,电机20可以体现为,设置在无论驱动轴16F或16R的驱动轮18上的轮毂电机不连接至发动机15。发动机15和电机20彼此分离,使得发动机扭矩(箭头TE)不可用于对电池组22充电。
图1的代表性混合动力系***12包括变速器(T)24,其经由行星齿轮布置(未示出)接收并将发动机扭矩(箭头TE)传递到所连接驱动轴,例如后驱动轴16R。尽管为了示例清楚和简洁从图1中省略,液力变矩器或输入离合器和减震器组件可以设置在发动机15和变速器24之间,以将发动机15与变速器24连接和断开。
发动机15可以经由示出为皮带和滑轮组件的驱动布置28连接至交流发电机(ALT)26。交流发电机26是发动机驱动发电机。在发电机模式中,交流发电机26通过辅助电压总线(VAUX)向辅助电池(BAUX)32的正端子和负端子(+,-)输出辅助充电电压,交流发电机26的操作由此保持辅助电池32的充电状态和/或根据需要将辅助电压供应至所连接辅助负载34(例如低压电力总线)、所连接照明效果、风挡玻璃刮水器电机13或洗涤器流体泵、娱乐***等。
在一些实施例中,电池组22可以体现为高压能量存储***,例如锂离子或镍金属氢化物推进电池组。在这种实施例中的辅助电池32可以经由辅助功率模块(APM)36电连接至电池组22,辅助功率模块36是直流-直流(DC-DC)电压转换器,其可操作用于将来自电池组22和高压总线(VHV)的总线电压降低至适合于对辅助电池32充电或为辅助负载34供电的辅助电平。
控制器14被编程为执行体现方法100的指令,其实例关于图2和图3在下面详细描述。控制器14可以是车辆10的其它电子控制器或控制处理器的整体部分,或可操作地连接至其它电子控制器或控制处理器的单独模块。控制器14可以包括处理器(P)和存储器(M),即,参与以可以由处理器(P)读取的形式提供数据或指令的暂时和非暂时(例如,有形)存储器。数据和指令可以由一个或多个传输介质或传递导体(例如,控制器区域网络总线)传输。
当执行方法100时,控制器14检测车辆10在低μ表面上的操作并且使用基于轴扭矩的滑移积分作为执行如下所述的动力系控制动作的开端。也就是说,当滑移被检测到并持续一段时间时,控制器14响应地执行各种控制动作或其组合以自动命令本文称为“天气模式”的命令。当在天气模式下操作时,电池组22的能量/充电状态被保留/保存并分配以支持推进和牵引控制目的,以排除为其它高压功能供电。为此,控制器14接收控制输入并实时生成各种控制输出,即,在混合动力系***12的持续操作期间。
如下所述,控制器14包括作为其编程逻辑的一部分的一对滑移积分器,其中为前驱动轴16F和后驱动轴16R中的每一个分别计算单独的积分器值。积分器值响应于车辆10的所报告轴扭矩(箭头TAXL)和牵引控制状态信号(箭头TC)随时间改变,从而使得牵引控制***19能够操作,牵引控制***19在检测到滑移时被触发或激活。尽管为了示例的简洁示意性地示出了牵引控制***19,但是本领域普通技术人员将认识到,这种牵引控制***19可以自动地使一个或多个驱动轮18的车辆制动器(未示出)循环以降低车轮速度并且减少车轮滑移,和/或可以减少从发动机15和/或电机20到滑移驱动轮18的扭矩分配。因此,控制器14在确定何时开始修改积分器值时查看这种牵引控制***19的逻辑状态,如下所述。为了示例简洁,示出了控制器14与动力系***12分开。然而,为了执行所公开的功能,控制器14可以可选地定位在电池组22和电机20之间,例如,与PIM29集成或者作为电机控制处理器或单独控制模块。
控制器14被配置为将相应的前驱动轴16F和后驱动轴16R的积分器值相加在一起,从而导出积分器和。响应于积分器和超过所校准积分器阈值,控制器14执行关于混合动力系***12的一个或多个控制动作,包括控制或改变操作模式,可能如下所解释包括控制发动机15的某些功能,并且节省电池组22的能量水平或充电状态,以便支持车辆10的牵引和推进功能。控制器14可以可选地考虑增加滑移严重性的多个不同阈值,然后逐渐执行绑定至超过特定阈值的不同控制动作。
更具体地,控制器14确定或接收来自ABS***17的所报告轴扭矩(箭头TAXL)、牵引控制状态信号(箭头TC)、车辆速度(箭头N10)以及可能的防抱死制动***状态信号(箭头ABS)。控制器14可以可选地接收附加信息,例如来自环境温度传感器11的环境温度信号(箭头TMP)和/或天气相关信息(箭头W),例如道路状况或风挡玻璃刮水器电机13的速度,控制器14可能使用附加信息修改控制动作,例如,如下所述实时调谐或调整滑移阈值。方法100的执行使得控制器14生成控制信号(箭头CCO),其最终控制混合动力系***12的操作,即,改变***12的操作状态。现在将参考图2和图3描述方法100的实施方式。
参考图2,方法100开始于图1的控制器14的起动和初始化,并且继续到逻辑块B102和B104。逻辑块B102和B104(每个逻辑块可以使用图3的子过程A来执行)包括启动用于图1的相应前驱动轴16F和后驱动轴16R的对应滑移积分器,即两个滑移积分器,每个滑移积分器对应于驱动轴16F或16R中的给定一个。可以认识到,在逻辑控制环路中使用的术语“积分器”是在给定的采样时间窗口内对特定信号值进行积分(即累加或求和)的逻辑元件。在图1的控制器14内,累加的信号值是在驱动轮18在低μ道路表面上滑移期间的所计算滑移增益,例如,由图1的牵引控制***19确定的这种滑移。积分器基于各种状况实时递增或递减。
用于实施逻辑块B102/B104的一种可能方法是图3中所示的子过程A。在逻辑块B1处,图1的控制器14根据所校准滑移阈值和上述所报告轴扭矩(图1的箭头TAXL)计算滑移增益值(calc KS),其中所校准滑移阈值是预定扭矩阈值,低于该阈值时牵引控制事件有效并且滑移积分器递增。所校准滑移阈值可以是相对于车辆速度的变化的函数和/或相对于车辆速度的变化而改变(图1的箭头N10)。即:
KS=(滑移阈值-TAXL)/滑移阈值
其中,当所报告轴扭矩(上面表示为TAXL)小于所校准滑移阈值时,滑移增益值(KS)为正,并且当所报告轴扭矩超过这个阈值时,滑移增益值为负,并且其中,轴扭矩为报告给控制器14的轴扭矩值的绝对值。
逻辑块B1前进到逻辑块B2,其中控制器14接下来确定是否经由逻辑块B2计算的滑移增益值(KS)是零还是更高,即,是否KS≥0。当滑移增益值等于或超过零时,方法100前进到逻辑块B3。当滑移增益值为负时,在替代方案中执行逻辑块B4。
逻辑锁B3可以包括确定车辆10上的牵引控制是否有效(“TC=1?”),即,使用图1中所示的牵引控制状态信号(箭头TC)。该逻辑块可能需要从牵引控制***19接收布尔值或真/1位标志,这种布尔值表示这种牵引控制***19经由自动轴扭矩改变主动控制滑移。当牵引控制有效时,逻辑块B3前进到逻辑块B4。然而,当牵引控制无效时,零值被前馈到节点40。
在前进到块B5之前,逻辑块B4包括将特定的一个驱动轴16F或16R的滑移积分器值(INT)的值修改为来自逻辑块B1的滑移增益值(KS)的量(“INT=INT+KS”)。基于滑移增益值(KS)的符号,积分器将相应地递增或递减。
在逻辑块B5处,控制器14接下来确定滑移积分器值是否具有负值(“INT<0?”)。当积分器值为负时,控制器14前进到逻辑块B6。当滑移积分器具有零或正值时,该值被馈送到节点40。
逻辑块B6包括将滑移积分器的值设置为零(“INT=0”),然后将该值传递给节点40。
在图3的节点40处,逻辑块B3、B5和B6输出(“**”)给定时间窗口的积分器的值。块B102/B104的逻辑流程确保滑移积分器值递增(在正方向上增加),特别是当牵引控制有效且所报告轴扭矩低于所校准滑移阈值时。当所报告轴扭矩超过所校准滑移阈值时,滑移积分器递减,即向下计数,这意味着认为存在足够的牵引。
在一个可能的实施例中,用于驱动轴16F和16R的积分器可以限于正值(包括零),其中积分器也具有最大值。也就是说,在存在滑移的情况下的延伸牵引事件期间,如果没有作为积分器限制的这种最大值,当道路状况最终充分改善以停用牵引控制***19时,积分器可能花费不合需要的长时间来倒计时/递减。因此,方法100可以包括将积分器值限制为所校准最大值。
再次参考图2,逻辑块B106接收来自各个前驱动轴16F和后驱动轴16R的积分器的子过程A的输出,并且前进到逻辑块B108之前将两个积分器的值相加。
在逻辑框B108处,图1的控制器14接下来确定来自逻辑块B106的和是否超过一个或多个所校准积分器和阈值。块108可以可选地包括使用增加滑移严重性的多个不同阈值,其中不同的控制动作可能与特定阈值绑定。当没有超过阈值时,方法100前进到逻辑块B110。当超过一个或多个这种阈值时,在替代方案中执行块B112。
当来自逻辑块B106的和不超过所校准积分器和阈值中的一个或多个时到达的块B110可以包括在天气模式中自动禁用操作,并且此后默认为标称动力系操作状态。例如,“标称”动力系操作状态可以包括执行“燃料经济性”模式,其中例如根据最小化发动机15对化石燃料的消耗的成本模型,控制器14和/或专用混合动力控制模块向推进电池组22分配能量并且从推进电池组22分配能量以为电机20提供能量,以及为其它高压部件(例如图1的APM36)供电和/或其它电压附件。
块B112需要执行关于图1的动力系12的控制动作。这可以包括如上所述的自动启用天气模式以节省仅用于支持牵引控制事件(即提供电力推进)的高压电池电力。响应于启用天气模式,控制器14可以基于在块B108处确定的严重性(例如,基于滑移积分器值超过积分器阈值的量值或量的高、中或低严重性)来执行各种控制动作。
响应于自动进入天气模式的实例控制动作对于使用方法100的混合动力系***12的配置是特定的。作为实例而非限制,并且使用图1的实例混合动力系***12作为参考,控制器14可以临时禁用发动机15的起动-停止功能。控制器14还可以从正常操作期间(即当天气模式有效时)使用的默认目标充电状态增加电池模块22的目标充电状态。例如,在可能的实施例中,如果默认目标充电状态是最大充电状态的约50-60%,则逻辑块B112可以包括将目标充电状态增加至少30%,例如,高达65-78%的充电状态。可以保持这种增加的目标充电状态,直到在执行方法100的过程中,控制器14最终退出天气模式。
其它可能的控制动作包括禁用发动机15的主动燃料管理(AFM)功能。这种类型的功能的一个实例是在巡航时命令主动气缸停用(该事件中,为了减少燃料消耗,图1的发动机15的一些气缸未被点火)。
同样可能的是自动禁用低节气门/踏板踩紧逻辑,即在光节气门期间的电动辅助的瞬态时段,其中在来自发动机15的扭矩响应的瞬态延迟或滞后期间,来自图1的电机20的电机扭矩(双向箭头TM)可以在同位的方向上(即,作为电机扭矩)被命令。控制器14还可以禁用图1的APM36或者至少限制APM36的功率输出,以便在天气模式下操作的持续时间内优先考虑从电池组22到电机20的能量分配。这可以包括经由图1的发动机15和交流发电机26临时为辅助功率负载34供电,而不是经由APM36。
作为逻辑块B112范围内预期的可能控制动作范围的一部分,图1的控制器14可以修改电池组22的通路充电策略。该动作可以响应于对于主轴的正滑移而发生牵引控制事件的阈值,该主轴是图1的非限制性实例中的后驱动轴16R。当主轴(例如后轴16R)的滑移没有主动发生时,这种操纵可以帮助最大化电池组22的可用充电水平。换句话说,可能的控制动作确保充电扭矩与主轴扭矩的和限于主轴的滑移阈值。可以在本公开的范围内设想这些和其它可能的控制动作。
详细描述和附图是对本公开的支持和描述,但是本公开的范围仅由权利要求限定。虽然已经详细描述了用于执行所要求保护的公开内容的一些最佳模式和其它实施例,但是存在用于实践所附权利要求中限定的本公开的各种替代设计和实施例。此外,附图中示出的实施例或本说明书中提到的各种实施例的特征不必被理解为彼此独立的实施例。而是,可以将实施例的一个实例中描述的每个特征与来自其它实施例的一个或多个其它期望特征组合,从而导致未在文字中或通过参考附图描述的其它实施例。因此,这种其它实施例落入所附权利要求的范围的框架内。
