但是，在专利文献1公开的结构中，对动力控制单元与该动力控制单元的周边部件的位置关系没有任何考虑。因此，例如，当用于从发动机排出废气的排气管等与动力控制单元相比成为高温的高温部件配置于动力控制单元的附近时，高温部件的热有可能对动力控制单元造成不良影响(热损害)。
本发明是鉴于上述课题做出的，其目的在于提供能够抑制高温部件的热对动力控制单元造成不良影响的混合动力车辆。
用于解决课题的技术方案
为了解决上述课题并达到目的，本发明涉及的混合动力车辆具备：内燃机；旋转电机；蓄电装置；及动力控制单元，在所述旋转电机与所述蓄电装置之间进行电力转换，并且进行所述旋转电机的控制，所述混合动力车辆能够使用所述内燃机和所述旋转电机的至少一方的动力使驱动轮旋转而行驶，其特征在于，所述动力控制单元设置于所述旋转电机的下方，从车辆宽度方向的一侧向另一侧，以与所述动力控制单元相比成为高温的热产生源、用于抑制热从所述热产生源向所述动力控制单元的传递的热传递抑制部、所述动力控制单元的顺序进行配置。
由此，本发明涉及的混合动力车辆将动力控制单元设置于旋转电机的下方，并且从车辆宽度方向的一侧向另一侧以热产生源、热传递抑制部、动力控制单元的顺序进行配置，由此动力控制单元不易受到来自热产生源的热，能够抑制热产生源的热对动力控制单元造成不良影响。
另外，也可以是，在上述说明中，所述混合动力车辆具备排出来自所述内燃机的废气的排气管，所述热产生源是所述排气管。
由此，能够抑制排气管的热对动力控制单元造成不良影响。
另外，也可以是，在上述说明中，所述旋转电机设置于所述内燃机与所述驱动轮之间的动力传递路径，所述混合动力车辆具备：连接/断开装置，连接或切断所述内燃机与所述旋转电机之间的动力传递路径；壳体构件，至少收容所述旋转电机及所述连接/断开装置；罩构件，覆盖在所述壳体构件的下部形成的开口；及固定构件，将罩构件可装卸地固定于所述壳体构件，所述动力控制单元收容于由所述壳体构件的下部和所述罩构件划分出的下部收容室。
由此，能够从混合动力车辆的下方拆下罩构件而容易地进行动力控制单元的更换作业。
另外，也可以是，在上述说明中，所述混合动力车辆具备：油底壳，设置于所述壳体构件的所述热产生源侧的侧部，储存有用于所述连接/断开装置的工作的工作油；及阀体，收容于由所述壳体构件的所述热产生源侧的侧部和所述油底壳划分出的侧部收容室，调整向所述连接/断开装置供给的液压，所述热传递抑制部是所述阀体。
由此，与动力控制单元相比具有耐热性的阀体能够抑制热从热产生源向动力控制单元的传递，从而能够更有效地抑制热产生源的热对动力控制单元造成不良影响。
另外，也可以是，在上述说明中，在所述壳体构件内设置有将所述旋转电机与所述动力控制单元电连接的汇流条。
由此，能够在壳体构件内直接进行旋转电机与动力控制单元的电连接。
另外，也可以是，在上述说明中，以在车辆前后方向上向前侧或后侧成凸形状的方式构成所述动力控制单元。
由此，通过缩短动力控制单元的车辆宽度方向的宽度，能够使设置动力控制单元的壳体构件的下部处的车辆宽度方向的宽度变窄，能够在车辆宽度方向上容易地确保周边部件与壳体构件之间的间隙。
发明效果
本发明涉及的混合动力车辆通过将动力控制单元设置于旋转电机的下方，并且从车辆宽度方向的一侧向另一侧，以热产生源、热传递抑制部、动力控制单元的顺序进行配置，由此取得动力控制单元不易受到来自热产生源的热而能够抑制热产生源的热对动力控制单元造成不良影响的效果。
附图说明
图1是表示实施方式涉及的混合动力车辆的概略结构的图。
图2是从车辆前后方向的前侧观察前模块及其周边的剖视图。
图3是表示将PCU以在车辆前后方向上向前侧成为凸形状的方式构成的情况的图。
具体实施方式
以下，对本发明涉及的混合动力车辆的实施方式进行说明。此外，本发明不被本实施方式限定。
图1是表示实施方式涉及的混合动力车辆1的概略结构的图。图2是从车辆前后方向的前侧观察前模块200及其周边的剖视图。
如图1所示，实施方式涉及的混合动力车辆1具备发动机2、减震装置3、旋转电机4、PCU(动力控制单元)5、蓄电池6、变矩器7、自动变速器8、输送机9、排气管21、废气净化催化剂装置22、连接/断开离合器40、油泵130、前传动轴101、前差速器102、前驱动轴103、前轮104、后传动轴105、后差速器106、后驱动轴107以及后轮108等。另外，在实施方式涉及的混合动力车辆1中，例如，旋转电机4、连接/断开离合器40以及变矩器7收容于作为壳体构件的壳体201而构成前模块200。
混合动力车辆1是能够使用发动机2和旋转电机4的至少一方的动力，从而使作为驱动轮的前轮104及后轮108旋转而行驶的4轮驱动的车辆。
发动机2是汽油发动机或柴油发动机等内燃机。在发动机2连接有形成用于排出废气的排气路的排气管21。排气管21构成为将废气向车身的后方侧排出。在排气管21的中途，设置有废气净化催化剂装置22。
减震装置3与发动机2的曲轴23连结。另外，在发动机2与旋转电机4之间的动力传递路径，设置有连接或切断该动力传递路径的作为连接/断开装置的连接/断开离合器40。连接/断开离合器40例如是通过液压进行摩擦卡合的湿式多板离合器，经由旋转轴31与减震装置3连结。
旋转电机4设置于发动机2与驱动轮之间的动力传递路径。旋转电机4是由转子41及定子42等构成的电动发电机，通过从蓄电池6经由PCU5供给的电力被驱动。另外，旋转电机4通过由从发动机2或驱动轮传递的动力使转子41旋转而发电，能够经由PCU5对蓄电池6进行充电。
PCU5在旋转电机4与蓄电池6之间进行电力转换，并且进行旋转电机4的控制，构成为将控制基板、变换器、电容器等电子部件收容在PCU壳体50内。PCU5与设置在用于与作为搭载于混合动力车辆1的蓄电装置的蓄电池6连接的电缆61的PN(正/负)连接器连接，蓄电池6和PCU5经由电缆61电连接。PN连接器62是蓄电池6与PCU5的连接部，是将蓄电池6的正负极与PCU5相连的两极的连接器。如图2所示，PCU5在壳体201内经由设置于端子台110的汇流条111与旋转电机4电连接。由此，旋转电机4经由PCU5与蓄电池6电连接。另外，在PCU5连接有供冷却液在内部流动的冷却器120，通过冷却器120进行PCU5的各电子部件的冷却。
变矩器7具备泵叶轮7a、涡轮转轮7b、定子7c、锁止离合器7d。泵叶轮7a经由旋转轴43与旋转电机4的转子41连结，能够与转子41的旋转联动地旋转。基于来自ECU10的控制信号，锁止离合器7d被控制为卡合状态、释放状态、半卡合状态中的任一种。
自动变速器8经由旋转轴71与变矩器7连结，设置于变矩器7与输送机9之间的动力传递路径。自动变速器8例如是能够选择性地形成变速比不同的多个档位的有级式的自动变速器。
输送机9将从自动变速器8输入的动力分配给前传动轴101和后传动轴105。分配给前传动轴101的动力经由前差速器102及左右的前驱动轴103传递给左右的前轮104。另外，分配给后传动轴105的动力经由后差速器106及左右的后驱动轴107传递给左右的后轮108。
机械式的油泵130经由圆筒状的连结构件131与变矩器7的泵叶轮7a连结，与泵叶轮7a的旋转联动地工作，吸入储存在后述的油底壳203的工作油而向阀体140喷出。在阀体140，设置有例如切换阀、液压控制阀以及液压回路等。阀体140例如将从油泵130供给的液压作为初压，在进行连接/断开离合器40及锁止离合器7d的卡合及释放的动作控制时，根据来自ECU10的控制信号分别调整向连接/断开离合器40及锁止离合器7d供给的连接/断开离合器40的控制液压、锁止离合器7d的控制液压。
如图2所示，前模块200在车辆宽度方向上配置在排气管21与前传动轴101之间。排气管21相对于壳体201在车辆宽度方向上向右侧隔开间隔地配置。前传动轴101相对于壳体201在车辆宽度方向上向左侧隔开间隔地配置。此外，排气管21和前传动轴101也可以相对于壳体201在车辆宽度方向上配置在左右相反的位置。
在壳体201，分别通过作为固定构件的螺栓211、212可开闭地固定有将形成于壳体201的排气管21侧的侧部的开口堵塞的油底壳203、和将形成于壳体201的下部的开口堵塞的底罩202。在由壳体201的排气管21侧的侧部和油底壳203划分出的侧部收容室204，储存有用于连接/断开离合器40及锁止离合器7d的工作的工作油，并且收容有阀体140。另外，在由壳体201的下部和底罩202划分出的下部收容室205，收容有PCU5。
在实施方式涉及的混合动力车辆1中，在壳体201的下部且旋转电机4的铅垂方向的下方，PCU5与旋转电机4以机电一体(在壳体201的内部直接进行旋转电机4与PCU5的电连接的构造)的方式搭载。另外，在实施方式涉及的混合动力车辆1中，在壳体201的车辆宽度方向上，在排气管21侧的侧部搭载阀体140，而使阀体140和前模块200在壳体201共存。由此，也能够确保排气管21、前传动轴101这样的前模块200的周边部件与PCU5及阀体140之间的间隙，并且能够在前模块200的周边配置PCU5及阀体140。
在实施方式涉及的混合动力车辆1中，通过在收容前模块200的壳体201的下部搭载PCU5，例如，在来自车辆侧方的碰撞时，能够降低由与周边部件的夹持等引起的PCU5的损伤风险。
另外，在实施方式涉及的混合动力车辆1中，通过在收容前模块200的壳体201的下部搭载PCU5，例如能够从由汽车用升降机抬起的混合动力车辆1的下方拆下底罩202而容易地进行PCU5的更换作业。
另外，在实施方式涉及的混合动力车辆1中，通过在收容前模块200的壳体201的下部搭载PCU5，与在壳体201的排气管21侧的侧部搭载PCU5的情况相比，能够使PCU5不易受到来自与PCU5相比成为高温的作为热产生源的排气管21的热，能够抑制排气管21的热对PCU5造成不良影响(热损害)。
另外，在实施方式涉及的混合动力车辆1中，从车辆宽度方向的右侧(一侧)向左侧(另一侧)，以排气管21、阀体140、PCU5的顺序进行配置。由此，比PCU5具有耐热性的阀体140作为用于抑制热从排气管21向PCU5的传递的热传递抑制部发挥功能，能够更有效地抑制排气管21的热对PCU5造成不良影响(热损害)。
图3是表示将PCU5以在车辆前后方向上向前侧成为凸形状的方式构成的情况的图。
在实施方式涉及的混合动力车辆1中，例如，如图3所示，也可以将PCU5构成为在车辆前后方向上向前侧成为凸形状。此时，在PCU5的凸部，例如，如图3所示，能够配置电容器51，或者配置与支承汇流条111的端子台110、PN连接器62连接的PCU侧端子等。通过将PCU5构成为在车辆前后方向上向前侧成为凸形状，能够缩短PCU5的车辆宽度方向的宽度。此外，PCU5也可以构成为在车辆前后方向上向后侧成为凸形状，在该情况下，也能够缩短PCU5的车辆宽度方向的宽度。这样，通过缩短PCU5的车辆宽度方向的宽度，能够使搭载PCU5的壳体201的下部处的车辆宽度方向的宽度变窄，能够容易地在车辆宽度方向上确保排气管21、前传动轴101等周边部件与壳体201之间的间隙。
