Description

插电式混合动力车辆
技术领域
本公开涉及插电式混合动力车辆，尤其涉及具有排气净化部的插电式混合动力车辆。
背景技术
一般而言，车辆的排气净化装置具有：氧化废气中的烃(HC)、一氧化碳(CO)的氧化催化剂、选择性还原净化废气中的氮化合物(NOx)的选择性还原催化剂等。由于氧化催化剂或选择性还原催化剂在低温时为惰性，因此为了有效地发挥这些催化剂的排气净化性能，需要使催化剂温度为催化剂活性温度以上。鉴于上述问题，例如，在专利文献1中公开了在氧化催化剂低于催化剂活性温度的情况下，使废气温度上升而将氧化催化剂升温至催化剂活性温度以上的燃料喷射控制技术。
[现有技术文献]
[专利文献]
专利文献1：日本特开2010-31833号公报
发明内容
但是，在专利文献1所公开技术中，由于仅使NOx催化剂的上游侧附近的入口附近的废气升温，因此不仅无法得到充分的升温效果，而且以行驶时燃料喷射为条件。因此，产生以下问题：在使车辆从停止状态开始行驶时，根据周边环境温度，到达到催化剂活性温度为止需要时间，而且需要复杂的喷射控制。
本公开的技术，通过在电池充电时利用加热器部进行加热，从而缩短了升温至催化剂活性温度的时间，且改善了燃料消耗性能。
[用于解决课题的手段]
本公开的插电式混合动力车辆，包括:燃料动力部，其利用液体燃料的燃烧；电动力部，其利用从可充电电池供给的电力；排气部，其与所述燃料动力部连通，对伴随所述液体燃料的燃烧而产生的废气进行排气；排气净化部，其配置在所述排气部的中途部，除去废气中含有的杂质；以及充电部，其与所述电池电连接，以外部电力进行充电。所述充电部包括加热器部，在所述燃料动力部和所述电动力部停止的状态下以外部电力向所述电池充电时，该加热器部利用蓄积在所述电池中的电力或外部电力对所述排气净化部进行加热。
在上述插电式混合动力车辆中，也可以是，所述充电部在来自监视所述排气净化部温度的温度检测部的温度达到规定温度以上时，停止所述加热部的加热。
在上述插电式混合动力车辆中，也可以是，在成为停止以外部电力向所述电池充电、并从所述燃料动力部和所述电动力部停止的状态起开始驱动的状态时，在来自监视所述排气净化部温度的温度检测部的温度未达到规定温度以上的情况下，所述充电部从所述电池供给电力，并继续所述加热部的加热。
在上述插电式混合动力车辆中，也可以是，在监视从所述燃料动力部的驱动开始起的暖机状态的暖机监视部检测到暖机完成状态时，所述充电部停止从所述电池向所述加热器部的电力供给。
在上述插电式混合动力车辆中，也可以是，在所述各动力部停止且不对所述电池进行外部电力的充电时，在来自对所述排气净化部温度进行监视的温度检测部的温度为规定温度以下、且所述电池的蓄电量为规定值以上的情况下，所述充电部从所述电池向所述加热器部供给电力，并对所述排气净化部进行预加热。
在上述插电式混合动力车辆中，也可以是，所述充电部在所述电池的蓄电量成为规定值以下时，停止所述预加热。
[发明效果]
根据本公开的技术，通过在电池充电时利用加热器部进行加热，从而能够缩短升温至催化剂活性温度的时间，实现燃料消耗性能的提高。
附图说明
图1是示出包括本公开一个实施例涉及的充电系统的插电式混合动力车辆的示意性整体结构图。
图2是说明本公开一个实施例涉及的ECU的作用的流程图。
图3是示出包括本公开的一个实施例涉及的另一充电系统的插电式混合动力车辆的示意性整体结构图。
具体实施方式
以下，基于附图，对本公开一个实施方式涉及的催化剂的升温装置进行说明。对相同的部件标注相同的符号，它们的名称和功能也相同。因此，不重复对它们的详细说明。另外，在各部分的名称中包含功能性表现的情况下，省略送假名的标记，与功能本身的表现进行区别。
图1是表示本实施方式的插电式混合动力车辆(以下简称为"车辆")1的示意性整体结构图。插电式混合动力方式(也称为PHV等)是能够并用电动汽车(EV模式)和混合动力车(HV模式)的方式。因此，所搭载的电池26能够由所谓家庭用的商用电源(外部电力)进行充电。
车辆1搭载了发动机DE作为动力源之一。发动机DE例如使用柴油发动机。因此，发动机DE作为利用液体燃料的燃烧的燃料动力部发挥功能。
柴油发动机省略了详细的结构(图示)，将蓄积在共轨中的高压化的燃料均匀地供给到配置在各燃烧室中的燃料喷射装置，从燃料喷射装置喷射高压的燃料，通过自点火使其完全燃烧，由此生成旋转能量。
由此，将减少包括作为黑烟源头的碳(C)在内的颗粒物(PM：Particulate Matter：粒状物质)的排放，并通过多次进行喷射，防止燃烧室的高温化，降低氮氧化物(NOx)。此时的燃料的喷射压力、喷射正时和次数、喷射量等由电子控制单元(以下也简称为"ECU"构成。)进行细致的控制。
另外，在作为柴油发动机的发动机DE中，能够采用各种燃料消耗率降低技术以及废气降低技术。
例如，可以采用利用发动机DE的排气能量来提高燃烧效率的涡轮增压器，以及通过冷却进气来提高燃烧效率的同时，能够降低二氧化碳(CO2)排出量的带中冷器的涡轮增压器。
此外，通过将排气再次与进气混合，降低燃烧室内的氧浓度，使燃烧缓慢，同时降低NOx的排气再循环(EGR：Exhaust Gas Recirculation)
另外，通过使每个气缸的进/排气阀分别设为2个，实现进气排气效率的提高，并且通过将燃料喷射装置配置在燃烧室的中央，实现均质的燃料喷射，也可以采用实现PM降低、高输出化、燃料消耗率的提高的四阀化。或者，也可以采用通过改变使燃烧室的进气绕中心轴旋转的涡流的产生来实现废气的降低和燃料效率的提高的可变涡流化。
发动机DE具有输出所生成的旋转能量的动力传递部10、动力取出机构部(以下也简称为"PTO：Power Take-Off")20、处理燃烧后的排气的排气处理部30、充电用的外部充电机构40、以及对它们进行电控制的ECU50。
动力传递部10包括离合器装置11、变速机(变速器)12、传动轴13、差速齿轮14、驱动轴15、以及左右驱动轮16。
由发动机DE生成的旋转能量根据离合器装置11的接通、断开而传递到变速机12。变速机12的动力经由传动轴13在保持旋转平衡的同时传递到差速齿轮14。差速齿轮14，以将传动轴13的绕轴方向的旋转力切换为直角并且保持转弯行驶时的旋转平衡的方式使驱动轴15旋转。驱动轴15将旋转力传递到左右驱动轮16。
动力取出机构20包括动力取出齿轮21、PTO轴22、PTO离合器23、电动发电机24、逆变器25、以及可充电电池26。因此，动力取出机构20作为利用了从可充电的电池26供给的电力的电动力部发挥功能。
动力取出齿轮21始终与变速机12的未图示的齿轮啮合。PTO轴22的一端侧与动力取出齿轮21连接，另一端侧与电动发电机24连接。PTO离合器23设置在PTO轴22上，将从动力取出齿轮21经由PTO轴22传递到电动发电机24的动力进行断开/连接。
电动发电机24例如在相对于与驾驶员对未图示加速踏板的操作量对应的要求转矩仅用发动机DE的输出转矩不足的情况下，将经由电池26向逆变器25供给的电力作为电动机进行驱动。另外，电动发电机24的驱动力从动力取出机构20通过动力传递部10辅助左右驱动轮16的旋转力。另一方面，电动发电机24在车辆1减速时，利用从左右驱动轮16经由动力传递部10传递的制动力进行发电驱动。伴随该发电驱动的再生电力经由逆变器25用于电池26的充电。
排气处理部30具有排气歧管31、排气通路(排气管)32、氧化催化剂(以下也简称为"DOC")33、柴油微粒过滤器(以下也简称为"DPF")34、尿素水添加喷嘴35、以及选择性催化还原部(以下也简称为"SCR")36。另外，排气处理部30通过作为温度检测部的第一排气温度传感器37和第二排气温度传感器38监视温度。因此，排气处理部30与发动机(燃料动力部)DE连通，构成对伴随液体燃料的燃烧而产生的废气进行排气的排气部。
排气歧管31与发动机DE的各排气口(未图示)连通，将来自各排气口的废气排出到一个排气通路32。
DOC33和DPF34构成对废气中含有的PM进行净化的废气净化装置(DPD：柴油机微粒扩散器)，通过反复进行PM的过滤器捕集和积存的PM的强制性处理和再生来连续地处理PM。因此，DOC33和DPF34配置在排气处理部(排气部)30的中途部，作为除去废气中含有的杂质的排气净化部发挥功能。
DOC33具有通过在规定温度(例如200℃)下对PM中的由未燃燃料或润滑油构成的SOF进行氧化净化来降低PM的功能。DOC33例如以铂(Pt)或钯(Pd)等贵金属为催化剂，使用废气的氧将PM中含有的以烃(HC)为主的未燃烧物质(SOF)氧化，转化为水和二氧化碳。DOC33例如在蜂窝结构体等的陶瓷载体表面担载氧化催化剂成分。DOC33在通过发动机DE的远后喷射或排气管喷射器的排气管喷射供给HC时，将其氧化而使排气温度上升。
DPF34例如沿着排气的流动方向配置由多孔质性的隔壁划分的多个室，交替地对这些室的上游侧和下游侧进行封孔。DPF34将废气中PM捕集到隔壁的细孔或表面，且当PM堆积估计量达到规定量时，实施将其燃烧除去的过滤器强制再生(自我再生)。过滤器强制再生通过远后喷射或排气管喷射向DOC33供给HC，使流入DPF34的废气的温度上升到PM燃烧除去温度以上(例如，600℃以上)来进行。
这样，DPF34是通过电子控制式共轨系统的细致的燃料喷射、采用排气节阀等进行的排气温度控制，从而使捕集的PM高效燃烧，并使过滤功能自我再生的后处理技术。此时，自我再生在车辆行驶中自动地进行、或者是使车辆1停车而强制地进行再生所谓强制再生，在上升到PM燃烧除去温度以上(例如，600℃以上)之前，PM几乎不能燃烧而保持捕集状态。
尿素水添加喷嘴35将从未图示的尿素水箱通过尿素水泵汲取的尿素水喷射到比SCR36靠上游侧的排气通路32。从尿素水添加喷嘴35向排气通路32喷射的尿素水通过废气的排气热而被水解，能够生成氨。
SCR(选择性催化剂还原部)36例如在多孔陶瓷载体上担载沸石等。SCR36发挥氮氧化物净化功能，即从尿素水添加喷嘴35将作为还原剂的尿素水吹到废气中而生成氨，并在规定的温度下(例如，200℃)，使氨与废气中的NOx反应，从而无害化为水和氮。SCR36的NOx削减率高，能够减少对燃料消耗率的不良影响。
第一排气温度传感器37配置在DOC33和DPF34之间，检测流入DPF34的废气的排气温度。
第二排气温度传感器38配置在SCR36的上游侧，检测流入SCR36的废气的排气温度。
外部充电机构40包括:经由充电连接器(例如插座)3与外部电力2连接充电端口41、充电器42、第一加热器部43以及第二加热器部44。因此，外部充电机构40作为与电池26电连接并以外部电力进行充电的充电部发挥功能。
充电端口41构成为能够插入经由电缆与外部电力2连接的充电连接器3。充电端口41是具有与充电连接器3的种类对应的连接口的端口，例如能够应对急速充电等。
充电器42电连接在充电端口41和电池26之间，将来自充电端口41的外部电力转换为能够对电池26进行充电的电力。外部充电机构40在车辆停车时将充电连接器3插入充电口41时，从外部电力2经由充电连接器3向充电端口41供给的外部电力经由充电器42向电池26充电。充电器42监视电池26的蓄电量。由此，在电池26达到规定的蓄电量时，结束基于外部电力的充电。
另外，充电器42具有作为电力转换器的功能，例如，为了从作为交流商用电源的外部电力2对作为以直流电流进行充电以及放电的锂离子电池的电池26进行充电，将来自外部电力2的供给电力变换为直流。因此，也可以将该充电器42的功能设置在充电连接器3上，而不使用充电器42。
如上所述，DPF34在上升到PM燃烧除去温度以上(例如600℃以上)之前，成为几乎不能使PM燃烧而保持捕集的状态。为了使DPF34达到PM燃烧除去温度，例如需要10分钟左右的连续行驶。
另外一方面，对电池26的充电优选在使用前预先完成，但实际上大多在即将使用之前进行。特别是在卡车等商业车(营业车)中，使用率高。因此，往往在使车辆1停止(使ACC断开)状态下，例如在未营业(行驶)的时间段进行充电，在下一营业开始时停止充电，紧接着起动车辆1(接通ACC)，开始行驶。因此，无论充电是否完成，都必须使车辆1行驶。
因此，鉴于难以确保通过空转等使DPF34的升温结束的时间状况，通过在充电中在DPF34的上游侧及下游侧强制地使温度上升，实现了达到PM燃烧除去温度的时间的缩短化。
具体而言，采用由电加热器构成各加热器部43、44，并配置在DPF34的上游侧及下游侧的加热系统。另外，各加热器部43、44也可以是其他方式的加热装置、或者蓄热式的蓄热装置或蓄热材料。因此，外部充电机构40作为配置在排气处理部30的中途部的排气净化部，以DOC33及SCR36为对象由各加热器部43、44加热。
第一加热器部43配置在DOC33的外周部分，对DOC33进行加热。因此，能够发挥DOC33净化性能。在车辆停车时充电连接器3插入充电端口41时，第一加热器部43经由电池26发热。第一加热器部43与ECU50电连接，由ECU50控制。第一加热器部43是电气式加热器。
在第一排气温度传感器37测定的排气温度为200℃以下的情况下，ECU50使第一加热器部43动作，在第一排气温度传感器37测定的排气温度超过200℃的情况下，ECU50控制使第一加热器部43不动作。因此，在排气温度超过200℃的情况下，能够防止第一加热器部43进行加热而无谓地消耗电力。鉴于这样的状况，将作为温度检测部之一的第一排气温度传感器37中的规定温度设定为200℃，但设定温度没有限定。
第二加热器部44设置在SCR36的外周部分，对SCR36进行加热。因此，能够发挥SCR36净化性能。第二加热器部44在车辆停车时将充电连接器3插入充电端口41时，经由电池26发热。第二加热器部44与ECU50电连接，由ECU50控制。第二加热器部44是电气式加热器。
在第二排气温度传感器38测定的排气温度为200℃以下的情况下，ECU50使第二加热器部44动作，在第二排气温度传感器38测定的排气温度超过200℃的情况下，ECU50控制使第二加热器部44不动作。因此，在排气温度超过200℃的情况下，能够防止第二加热器部44进行加热而无谓地消耗电力。鉴于这样的状况，将作为温度检测部之一的第二排气温度传感器38中的规定温度设定为200℃，但设定温度没有限定。
ECU50是进行车辆1的各种控制的设备，包括公知的CPU、ROM、RAM、输入端口、输出端口等。ECU50包括PTO离合器23、电动发电机24、逆变器25、尿素水添加喷嘴35、第一排气温度传感器37、第二排气温度传感器38、第一加热器部43、以及第二加热器部44电连接。
ECU50代替充电器42(或并用)监视电池26的蓄电量和点火开关(ACC)的接通/断开。
在这样的结构中，车辆1包括：利用液体燃料的燃烧的发动机DE；利用从可充电的电池26供给的电力的动力取出机构20；与发动机DE连通，对伴随液体燃料的燃烧而产生的废气进行排气的排气处理部30；配置在排气处理部30的中途部，除去废气中含有的杂质的DOC33和SCR36；以及，与电池26电连接而以外部电力2进行充电的外部充电机构40。外部充电机构40包括：在各动力部DE、20停止的状态下将外部电力2向电池26充电时，利用电池26中储存的电力对DOC33以及SCR36进行加热的第一加热器部43及第二加热器部44。
接着，基于图2的流程图说明由ECU50控制各加热器部43、44的加热的情况的例子。
(步骤S1)
在步骤S1中，ECU50除了ACC开关处于断开状态时来自各传感器37、38的检测温度之外，例如还取得ACC开关断开后的经过时间、来自外部气温传感器的周边环境温度等。由此，ECU50推定DOC33的出口附近的温度以及SCR的入口附近的温度是否为催化剂活性温度以下。即，ECU50即使在车辆1刚刚结束行驶之后等、DOC33及SCR36处于催化剂活性温度附近，也不需要执行加热，因此，事先根据这些经过时间或温度等推定是否为催化剂活性温度以下。另外，由于存在由于怠速限制等而频繁地断开ACC可能性，因此无需每次检测充电的有无等，因此事先根据这些经过时间或温度等推定是否为催化剂活性温度以下。因此，考虑到ECU50的简化，该程序也可以不执行。ECU50在基于来自各传感器37、38的检测温度等推定为催化剂活性温度以下的情况下(是)，转移到步骤S2。ECU50在未推定来自各传感器37、38的检测温度为催化剂活性温度以下的情况下(否)，继续监视该程序。
(步骤S2)
在步骤S2中，ECU50判定是否通过外部充电机构40对电池26进行外部电力的充电。ECU50在判定为正在进行外部电力的充电的情况下(是)，转移到步骤S3。ECU50在未判定为正在进行外部电力的充电的情况下(否)，继续监视该程序。
(步骤S3)
在步骤S3中，ECU50判定电池26的蓄电量(SOC)是否为规定值以上。ECU50在电池26蓄电量为规定值以上的情况下(是)，转移到步骤S4。ECU50在未判定为电池26的蓄电量为规定值以上的情况下(否)，为了优先进行外部充电而向步骤S2循环。另外，相对于电池26的蓄电量的规定值，除了换算为在将所谓的满充电设为100％时，根据剩余的蓄电量，使用电池26行驶的大致行驶距离等电池26本身的蓄电量以外，也可以换算为可行驶距离等。另外，电池26的蓄电量或大致的可驱动时间等可以使用公知的电池监视技术。
(步骤S4)
在步骤S4中，ECU50通过来自电池26的电力供给使各加热器部43、44接通，转移到步骤S5。
(步骤S5)
在步骤S5中，ECU50判定外部充电是否继续。ECU50在判定为外部充电继续的情况下(是)，转移到步骤S6。ECU50在未判定为外部充电继续的情况下(否)，即充电连接器3从充电口41拔出，车辆1开始行驶的情况下，跳到步骤S7。
(步骤S6)
在步骤S6中，ECU50监视通过各加热器部43、44对DOC33及SCR36加热，来自各传感器37、38的温度是否达到规定温度以上。ECU50在判定为达到了规定温度的情况下(是)，转移到步骤S7。ECU50在未判定为达到规定温度的情况下(否)，循环到步骤S4，继续该程序，直到判定为充电完成或充电中止为止。此时，也可以使ECU50的循环向步骤S3循环。即，由于某种原因(例如，电池26劣化)，在消耗(加热器加热)比电池26的充电大的情况下，由于是电池26的蓄电量减少的环境，因此在这样的情况下优先充电。
(步骤S7)
在步骤S7中，ECU50停止对各加热器部43、44的电力供给，结束该程序。此时，由于设想到电池26达到满充电为止需要时间的情况，因此该一系列的程序包括中断，循环(返回)到步骤S1～步骤S3中的任一程序。
但是，在图2的流程中，ECU50在各动力部DE、20停止的状态下以外部电力2向电池26充电时，在通过各加热器部43、44加热DOC33和SCR36情况进行了说明。但是，ECU50在加热停止等时也能够进行各种控制。
例如，外部充电机构40在来自监视DOC33以及SCR36的温度的各传感器37、38的温度达到规定温度以上时，也可以停止基于各加热器部43、44的加热。由此，不需要无用地消耗多余的加热或电池26的蓄电量。
另外，ECU50在由用户停止了对电池26的外部电力的充电时，对其进行检测。之后，ECU50在检测到各动力部DE、20驱动开始时，在来自各传感器37、38的温度未达到规定温度以上的情况下，优选从电池26供给电力，继续利用各加热器部43、44进行加热。由此，能够确保更迅速升温。
另外，ECU50也可以在从发动机DE的驱动开始检测到暖机完成状态时，停止从电池26向各加热器部43、44的电力供给。由此，能够有助于ECU50对发动机整体的控制的简化。
另外，ECU50也可以在各动力部DE、20停止、未对电池26进行外部电力的充电时，来自各传感器37、38的温度为规定温度以下，并且，在电池26的蓄电量为规定值以上的情况下，进行预加热。
预加热是在通过各加热部43、44加热DOC33以及SCR36时，控制向各加热器部43、44的电力供给使得成为设定得比规定温度低的预热温度(例如，100°～150°范围的任意的温度)。另外，在电池26的蓄电量有富余的情况下的寒冷地区等，能够事先进行加热。
另外，外部充电机构40也可以在电池26的蓄电量成为规定值以下时，停止预加热。这是为了抑制电池的蓄电量消失的情况。
另外，本公开不限于上述实施方式，在不脱离本公开的主旨的范围内，可以进行适当变形来实施。
例如，公开了各加热器部43、44在车辆停车时充电连接器3插入充电端口41时，从电池26接受电力供给而发热的结构，但是，如图3所示，也可以从充电端口41直接接受电力供给。
另外，发动机DE不限于柴油发动机，也可以广泛地适用于汽油发动机等其他内燃机。
进而，第一加热器部43以及第二加热器部44根据第一排气温度传感器37及第二排气温度传感器38检测出规定温度，可以独立地对任一方进行ON/OFF控制。在这种情况下，例如，可以根据作为加热对象的DOC33和SCR36所使用的材料(例如厚度、大小、热传导特性等)或催化剂活性温度进行设定、变更。
例如，在上述实施方式中，示出了在对电池26进行充电时，第一加热器部43以及第二加热器部44将DOC33和SCR36加热至能够确保一定净化率的催化活性温度(例如200℃)的情况。由此，能够在行驶前使DOC33及SCR36迅速升温至催化剂活性温度，而不会大幅降低对电池26的充电效率。但是，该规定温度也可以设定为成为更高净化率的催化剂活性温度(例如300℃)。
在本公开的插电式混合动力车辆中，通过在电池充电时利用加热器部进行加热来缩短升温至催化剂活性温度的时间，由此，具有实现燃料消耗性能的提高的效果，能够应用于全部包括排气净化部的插电式混合动力车辆。
