Description
技术领域
本发明涉及混合动力车辆,且详细地涉及能够执行向外部装置进行外部供电的混合动力车辆。
背景技术
常规地,作为此类型的混合动力车辆,已提出了可从外部电源充电的插电式混合动力车辆,所述混合动力车辆估计了罐的蒸发燃料吸收状态,且基于估计的吸收状态和行驶载荷从电动行驶切换到混动行驶,在所述混动行驶中发动机被驱动(例如,日本专利申请公开No.2009-085036)。插电式混合动力车辆基于罐的蒸发燃料吸收状态执行混动行驶。因此,甚至具有关于发动机驱动而言的很少的时间和频度的插电式混合动力车辆能够确定地将在罐中吸收的蒸发的燃料清除到发动机。在此,车辆基于外侧空气温度估计罐的蒸发燃料吸收状态。
作为混合动力车辆,存在不仅接收来自外部电源的充电而且向车辆外侧的外部装置供电的混合动力车辆。在此情况中,当电池的蓄电状态SOC由于外部供电而变低时,混合动力车辆起动发动机,且通过使用来自发动机的动力以发电机生成的电力为电池充电。在外部供电期间的这样的发动机驱动被执行用于某种程度的电池充电。因此,发动机的运行时间经常是短的,且将在罐中吸收的蒸发的燃料清除到发动机的执行条件经常不满足。同时,在外部供电期间,车辆处于停止,且因此罐清除对于可驾驶性的影响比在行驶期间更小。
发明内容
本发明提供了一种混合动力车辆,所述混合动力车辆增加了清除在罐中吸收的蒸发的燃料的机会。
根据本发明的一个方面的混合动力车辆是如下一种混合动力车辆,所述混合动力车辆包括:发动机,该发动机接收在燃料箱中储存的燃料的供给且输出动力;罐,该罐吸收在燃料箱中产生的蒸发的燃料;清除阀,该清除阀附接到供给管,所述供给管是将蒸发的燃料气体供给到发动机的进气管的管,蒸发的燃料气体包含被罐吸收的蒸发的燃料;电子控制单元,所述电子控制单元构造为执行清除阀的开闭控制,使得蒸发的燃料气体被供给到进气管;发电机,该发电机使用来自发动机的动力发电;电池,该电池通过电力线与发电机连接;和外部供电设备,该外部供电设备执行外部供电,通过所述外部供电将电力线上的电力供给到外部装置,其中电子控制单元构造为在外部供电设备正在执行外部供电的情况中使用执行条件执行清除阀的开闭控制,所述执行条件是与在外部供电设备不在执行外部供电的情况中相比蒸发的燃料气体更容易地被供给到进气管的条件。
在外部供电设备正在执行外部供电的情况中,根据本发明的以上方面的混合动力车辆使用执行条件执行被附接到供给管的清除阀的开闭控制,通过所述供给管将蒸发的燃料气体供给到发动机的进气管,在所述执行条件下与在外部供电设备不在执行外部供电的情况中相比更容易地将蒸发的燃料气体从罐供给到发动机的进气管。因此,在外部供电设备正在执行外部供电的情况中,蒸发的燃料气体从罐到进气管的供给(所谓的罐清除)被容易地执行。作为结果,可增加执行罐清除的机会,且提高蒸发排放性能。此外,可抑制由于在外部供电之后由于罐清除导致的发动机的运行时间的增加。
在根据本发明的以上方面的混合动力车辆中,在外部供电设备不在执行外部供电的情况中,执行条件可以是发动机的冷却水的温度是第一温度或更高的温度的条件,且在外部供电设备正在执行外部供电的情况中,执行条件可以是发动机的冷却水的温度是第二温度或更高的温度的条件,第二温度低于第一温度。因此,在外部供电设备正在执行外部供电的情况中,与在外部供电设备不在执行外部供电的情况中相比,在发动机起动之后可更早地执行罐清除。
此外,在根据本发明的以上方面的混合动力车辆中,在外部供电设备不在执行外部供电的情况中,执行条件可以是最大清除率是第一清除率的条件,且在外部供电设备正在执行外部供电的情况中,执行条件可以是最大清除率是第二清除率的条件,第二清除率高于第一清除率。因此,在外部供电期间可迅速地完成罐清除。

发动机22由发动机电子控制单元(在后文中称为“发动机ECU”)24控制。发动机ECU24构造为定心在CPU 24a上的微处理器,且除CPU 24a之外包括其中存储了处理程序的ROM24b、其中临时地存储了数据的RAM 24c和未图示的输入和输出端口和未图示的通信端口。发动机ECU 24通过输入端口接收来自检测发动机22的状态的多种传感器的信号。将通过输入端口输入的信号例如包括如下:来自曲柄位置传感器140的曲柄位置,曲柄位置传感器140检测曲轴26的旋转位置;来自水温传感器142的冷却水温度Tw,该水温传感器检测发动机22的冷却水的温度;来自未图示的压力传感器的气缸压力,该压力传感器附接在燃烧室中;来自凸轮位置传感器144的凸轮位置,该凸轮位置传感器144检测用于打开和关闭用来执行燃烧室的进气和排气的进气门128和排气门的凸轮轴的旋转位置;来自节气门位置传感器146的节气门位置,该节气门位置传感器146检测节气门124的位置;来自空气流量计148的吸入空气量Qa,该空气流量计148附接到进气管125;来自温度传感器149的进气温度,该温度传感器149类似地附接到进气管125;来自温度传感器134b的催化剂温度Tc,该温度传感器134b检测净化催化剂134a的温度;来自空燃比传感器135a的空燃比AF;和来自氧传感器135b的氧信号。此外,发动机ECU 24通过输出端口输出用于驱动发动机22的多种控制信号。将通过输出端口输出的控制信号例如包括如下:到燃料喷射阀126的驱动信号;到节气门马达136的驱动信号,节气门马达136调节节气门124的位置;到与点火器整合的点火线圈的控制信号;到可改变进气门128的开闭正时的可变气门正时机构150的控制信号;到燃料泵162的驱动信号;和到清除控制阀178的控制信号。与混合动力电子控制单元70通信的发动机ECU 24通过来自混合动力电子控制单元70的控制信号执行发动机22的运行控制,且按需要地输出与发动机22的运行状态有关的数据。在此,发动机ECU 24基于来自曲柄位置传感器140的曲柄位置计算曲轴26的速度,即发动机22的速度Ne。
行星齿轮30构造为单小齿轮型行星齿轮机构。行星齿轮30的太阳齿轮与马达MG1的转子连接。行星齿轮30的环齿轮与驱动轴36和马达MG2的转子连接,所述驱动轴36通过差速齿轮37与驱动轮38a、38b链接。行星齿轮30的行星架与发动机22的曲轴26连接。
马达MG1例如构造为同步发电机-马达。如上所述,马达MG1的转子与行星齿轮30的太阳齿轮连接。马达MG2例如构造为同步发电机-马达。如上所述,马达MG2的转子与驱动轴36连接。利用电力线54将逆变器41、42与电池50连接在一起。马达MG1、MG2的旋转驱动由马达电子控制单元(后文中称为“马达ECU”)40通过对于逆变器41、42的未图示的多个切换元件的切换控制来执行。
马达ECU 40构造为未图示的定心在CPU上的微处理器,且除CPU外包括其中存储了处理程序的ROM、其中临时地存储了数据的RAM、输入和输出端口和通信端口。马达ECU 40通过输入端口接收来自对于马达MG1、MG2的驱动控制而言所必需的多种传感器的信号。来自多种传感器的信号例如包括如下:来自检测马达MG1、MG2的转子的旋转位置的旋转位置检测传感器43、44的旋转位置θm1、θm2;和来自检测以马达MG1、MG2的相位流动的电流的电流传感器的相电流。马达ECU 40通过输出端口将切换控制信号输出到逆变器41、42的未图示的切换元件等。马达ECU 40与HVECU 70通过通信端口连接。马达ECU 40通过来自HVECU 70的控制信号执行马达MG1、MG2的驱动控制。此外,马达ECU 40按需要将与马达MG1、MG2的驱动状态有关的数据输出到HVECU 70。马达ECU 40基于从旋转位置检测传感器43、44获得的马达MG1、MG2的转子的旋转位置θm1、θm2计算马达MG1、MG2的转速Nm1、Nm2。
电池50例如构造为锂离子二次电池,且如上所述利用电力线54而与逆变器41、42连接在一起。电池50由电池电子控制单元(在后文中称为“电池ECU”)52管理。
电池ECU 52构造为未图示的定心在CPU上的微处理器,且除CPU外包括:其中存储了处理程序的ROM、其中临时地存储数据的RAM、输入和输出端口和通信端口。电池ECU 52通过输入端口接收来自对于管理电池50而言所必需的多个传感器的信号。来自多个传感器的信号例如包括如下:来自布置在电池50的终端之间的电压传感器51a的电池电压Vb;来自附接到电池50的输出终端的电流传感器51b的电池电流Ib(当电池50执行放电时,该值为正);和来自附接到电池50的温度传感器51c的电池温度Tb。电池ECU 52通过通信端口与HVECU70连接。电池ECU 52按需要将与电池50的状态有关的数据输出到HVECU 70。电池ECU 52基于来自电流传感器51b的电池电流Ib的积分值计算蓄电状态SOC。蓄电状态SOC是电池50的可放电的电力容量与电池50的总容量的比。此外,电池ECU 52基于计算出的蓄电状态SOC和来自温度传感器51c的电池温度Tb计算输入和输出极限Win、Wout。输入和输出极限Win、Wout是电池50可充电和放电的最大可允许电力。
外部供电设备60与电力线54和电力出口64连接,所述电力出口用于与不作为车辆的组成元件的外部装置连接。外部供电设备60包括未图示的逆变器。逆变器将电力线54上的直流电力转换为带有希望的电压的交流电力(例如,带有AC 100V的电力),且将交流电力供给到与电力出口64连接的外部装置。在后文中,在电力线54上的电力到外部装置的供给也称为“外部供电”。在逆变器中,未图示的多个切换元件的切换控制由HVECU 70执行。
HVECU 70构造为未图示的定心在CPU上的微处理器,且除CPU外包括:其中存储了处理程序的ROM、其中临时存储了数据的RAM、输入和输出端口和通信端口。HVECU 70通过输入端口接收来自多种传感器的信号。来自多种传感器的信号例如包括如下:来自电力传感器62的供给电力Ph,电力传感器62检测通过外部供电设备60进行的外部供电的供给电力;来自点火开关80的点火信号;来自检测换档杆81的操作位置的换档位置传感器82的换档位置SP;来自检测加速器踏板83的步进量的加速器踏板位置传感器84的加速器位置Acc;来自检测制动器踏板85的步进量的制动器踏板位置传感器86的制动器踏板位置BP;和来自速度传感器88的车辆速度V。HVECU 70通过输出端口向外部供电设备60的逆变器的切换元件输出切换控制信号等。如上所述,HVECU 70通过通信端口与发动机ECU 24、马达ECU 40和电池ECU 52连接。HVECU 70与发动机ECU 24、马达ECU 40和电池ECU52交换多种控制信号。
在此,在根据实施例的混合动力车辆20中,作为被换档位置传感器82检测到的换档位置SP,存在如下位置:在驻车时使用的驻车位置(P位置)、用于向后行驶的倒档位置(R位置)、处于空档的空档位置(N位置)、用于向前行驶的驱动位置(D位置)等。然而,当换档位置SP处于P位置时,驱动轮38a、38b被未图示的驻车锁定机构锁定。
根据以此方式构造的该实施例的混合动力车辆20基于加速器位置Acc和车辆速度V设定用于驱动轴36的要求驱动动力,且执行发动机22和马达MG1、MG2的运行控制,使得将与要求驱动动力可比较的要求动力输出到驱动轴36。作为发动机22和马达MG1、MG2的运行模式,存在如下模式(1)至(3):(1)转矩转换运行模式:在该模式中执行发动机22的运行控制,使得从发动机22输出对应于要求动力的动力,且执行马达MG1、MG2的驱动控制,使得将从发动机22输出的所有动力的转矩转换通过行星齿轮30和马达MG1、MG2来执行且将要求动力输出到驱动轴36;(2)充电/放电运行模式,在该模式中执行发动机22的运行控制使得从发动机22输出与要求动力和对于电池50的充电或放电所必需的电力的加和可比较的动力,且执行马达MG1、MG2的驱动控制使得在电池50充电/放电的情况下将从发动机22输出的动力中的全部动力或一些动力的转矩转换通过行星齿轮30和马达MG1、MG2来执行,并且将要求动力输出到驱动轴36;和(3)马达运行模式,在该模式中停止发动机22的运行且执行马达MG2的驱动控制,使得将要求动力输出到驱动轴36。
此外,当换档位置SP处于P位置时,根据实施例的混合动力车辆20基本上停止了发动机22的运行。然后,当由于未图示的辅助机器(空气调节设备等)的电力消耗、通过外部供电设备60进行的外部供电等使得电池50的蓄电状态SOC变成等于或小于先前决定的阈值Sst时,马达MG1通过转动曲轴起动发动机22。然后,发动机22和马达MG1被控制为使得通过马达MG1使用来自发动机22的动力进行发电来对电池50充电。在后文中,该控制称为“预先确定的充电控制”。然后,当电池50的蓄电状态SOC变成等于或大于比阈值Sst更大的阈值Ssp时,预先确定的充电控制结束,且发动机22的运行停止。
然后,将描述根据以此方式构造的该实施例的混合动力车辆20的行为,特别是在罐清除方面的行为。图3是示出了当确定由于在罐174中蒸发的燃料被吸收到一定程度而必需执行罐清除时被发动机ECU 24执行的示例性的清除执行过程的流程图。该过程以预先确定的时间间隔(例如,每数秒)重复地执行,直至罐清除被执行。
当清除执行过程被执行时,发动机ECU 24首先确定外部供电设备60是否正在执行外部供电(步骤S100)。该确定可通过如下方式执行,即通过通信接收HVECU 70是否正在执行由外部供电设备60进行的外部供电的控制信号(例如,标志),且检查接收到的控制信号。
在外部供电设备60不在执行外部供电的情况中,先前决定的温度T1(例如,35℃、40℃等)被设定为水温阈值Tref以用于确定是否允许罐清除(步骤S 110),且将先前决定的值P1(例如,8%、10%等)设定为最大清除率Pmax(步骤S120)。在此,清除率是蒸发的燃料气体量与吸入空气量的比(蒸发的燃料气体量/吸入空气量)。最大清除率Pmax是在罐清除中允许的清除率的最大值。然后,确定发动机22是否运行(步骤S150),且当发动机22不运行时,该过程结束而不执行罐清除。当发动机22运行时,输入来自水温传感器142的冷却水温度Tw(步骤S160),且确定冷却水温度Tw是否是水温阈值Tref或更高(步骤S170)。当冷却水温度Tw低于水温阈值Tref时,该过程结束而不执行罐清除。当冷却水温度Tw是水温阈值Tref或更高时,执行罐清除(步骤S180),且然后过程结束。在罐清除时,蒸发燃料清除系统170的清除控制阀178的开度在最大清除率Pmax的范围内调节,且蒸发的燃料被从罐174清除到进气管125。
另一方面,当在步骤S100中确定外部供电设备60正在执行外部供电时,水温阈值Tref设定为温度T2(例如,20℃、25℃等),所述温度T2低于当外部供电设备60不在执行外部供电时的温度T1(步骤S130),且最大清除率Pmax设定为值P2(例如,18%、20%等),所述值P2大于当外部供电设备60不在执行外部供电时的值P1(步骤S140)。然后,使用温度T2的水温阈值Tref和值P2的最大清除率Pmax,执行步骤S150至S180的过程。即,当发动机22不在运行时或当冷却水温度Tw低于水温阈值Tref时不执行罐清除,且当发动机22运行且冷却水温度Tw是水温阈值Tref或更高时执行罐清除。因此,与其中外部供电设备60不在执行外部供电的情况相比,在其中外部供电设备60正在执行外部供电的情况中,当冷却水温度Tw等于或高于比温度T1更低的温度T2时执行罐清除。因此,即使当冷却水温度Tw低于温度T1也可执行罐清除。因此,可增加执行罐清除的机会。此外,在此情况中,在设定为比值P1更大的值P2的最大清除率Pmax的范围内执行罐清除,且因此可迅速地完成罐清除。在此,可在外部供电期间使用冷却水温度Tw是较低的温度T2或更高且最大清除率Pmax是较大的值P2的条件而执行罐清除的原因是车辆在外部供电期间处于停止。即,这是因为认为在车辆处于停止的同时对于可驾驶性的影响是小的,即使在发动机22的速度由于罐清除而波动时也是如此。
在根据以上实施例的混合动力车辆20中,在其中外部供电设备60不在执行外部供电的情况中,当发动机22运行中且冷却温度Tw等于或高于设定为水温阈值Tref的温度T1时,执行罐清除。另一方面,在其中外部供电设备60正在执行外部供电的情况中,当发动机22运行且冷却水温度Tw等于或高于设定为水温阈值Tref的温度T2(T2<T1)时,执行罐清除。即,与其中外部供电设备60不在执行外部供电的情况相比,在其中外部供电设备60正在执行外部供电的情况中,当冷却水温度Tw等于或高于比温度T1更低的温度T2时,执行罐清除。因此,可增加执行罐清除的机会,且提高蒸发排放性能。此外,可抑制由于在外部供电结束之后由于罐清除导致的发动机22的运行时间的增加。
此外,在根据实施例的混合动力车辆20中,在其中外部供电设备60不在执行外部供电的情况中,在设定为值P1的最大清除率Pmax的范围内执行罐清除。另一方面,在其中外部供电设备60正在执行外部供电的情况中,在设定为比值P1更大的值P2的最大清除率Pmax的范围内执行罐清除。因此,在其中外部供电设备60正在执行外部供电的情况中,与其中外部供电设备60不在执行外部供电的情况相比可更快地完成罐清除。
在根据实施例的混合动力车辆20中,在其中外部供电设备60正在执行外部供电的情况中,使用值P2的最大清除率Pmax执行罐清除,所述值P2比在其中外部供电设备60不在执行外部供电的情况中更大。然而,即使在其中外部供电设备60正在执行外部供电的情况中,也可使用在外部供电设备60不在执行外部供电的情况中使用的值P1的最大清除率Pmax来执行罐清除。
在根据实施例的混合动力车辆20中,来自马达MG2的动力被输出到与驱动轮38a、38b链接的驱动轴36。然而,如在根据图4中的修改的混合动力车辆120中所列示,来自马达MG2的动力可输出到车轴(在图4中的与车辆39a、39b连接的车轴),所述车轴和与驱动轮38a、38b连接的车轴不同。
根据实施例的混合动力车辆20采取了如下构造,其中发动机22和马达MG1通过行星齿轮30与和驱动轮38a、38b链接的驱动轴连接,且马达MG2与驱动轴36连接。然而,如在根据图5中的修改的混合动力车辆220中所例示,可允许采取如下构造,即其中马达MG通过变速器230与和驱动轮38a、38b链接的驱动轴36连接,且发动机22通过离合器229与马达MG的旋转轴连接。为了在外部供电设备60正在执行外部供电的同时起动发动机22且通过以马达MG生成的电力为电池50充电,混合动力车辆220仅需要使离合器229接合且将变速器230换档到空档。此外,本发明可应用于所谓的串联混合动力车辆。
将描述在实施例的主要元件和在“发明内容”的部分中描述的发明的主要元件之间的对应关系。在实施例中,发动机22对应于“发动机”,罐174对应于“罐”,清除控制阀178对应于“清除阀”,发动机ECU 24对应于“电子控制单元”,马达MG1对应于“发电机”,电池50对应于“电池”,且外部供电设备60对应于“外部供电设备”。
在此,实施例是用于具体地描述用于实施在“发明内容”部分中所述的本发明的模式的示例,且因此实施例的主要元件和在“发明内容”部分中描述的发明的主要元件之间的对应关系不限制在“发明内容”部分中描述的发明的元件。即,在“发明内容”部分中描述的发明应基于在该部分中的描述来解释,且实施例仅是在“发明内容”部分中描述的发明的特定的示例。
因此,用于实施发明的模式已使用实施例来描述。然而,本发明根本不限制于实施例,且当然本发明可实施为在不偏离本发明的精神的范围内的多种模式。
本发明可用于混合动力车辆的制造工业等中。
