发明内容
发明要解决的课题
在于专利文献1中记载的方案中，比如，在车辆的制动时，通过第1电动发电机和第2电动发电机，产生再生电力，但是，由于为了使车辆不产生异常的举动，使姿势稳定，调整前后的再生制动器的制动量，故在制动中，相应的再生电力变动。为了将像这样而变动的再生电力积蓄到共同的电池中，具有控制非常复杂的问题。于是，于专利文献2中，通过下述的方式，提出上述的问题的解决方案，该方式为：设置电源装置，该电源装置仅仅对以只在其与从动轮之间传递动力的方式设置的电动发电机，进行供电，并且仅仅积蓄来自电动发电机的再生电力。
但是，按照专利文献2的方案，辅助电力系统形成下述的机构，其中，电池和电动发电机连接，上述电动发电机经由离合器、动力分配机构、驱动轴将动力传递给从动轮(轮胎)。由此，通过装载辅助动力系统，如上所述，形成与4轮驱动车等同的部件结构，结构复杂，车辆重量也增加。
另外，在不需要电动发电机时，通过切换离合器，不与从动轮连接，但是，由于动力分配机构、驱动轴与从动轮连接，故行驶阻力增加。另外，由于装载电动发电机专用的电池，故人们认为其重量增加，并且因电池的充电状态，耗油量恶化。
本发明的目的在于提供一种车辆动力辅助系统，其中，可进行从动轮的驱动辅助、再生驱动、发电，可提高行驶性能、制动性能、燃料消耗量等的车辆性能，并且用于获得辅助驱动力的结构简单即可，还可抑制车辆的重量的增加。本发明的另一目的在于布线方面和可靠性确保的方面优良。本发明的再一目的在于提供一种车辆从动轮再生系统，其中，可进行从动轮的再生制动、发电，使制动性能、燃料消耗量等的车辆性能提高，并且谋求部件数量的减少，使结构简化，还可抑制车辆的重量的增加。在下面，采用表示实施方式的附图中的标号，对本发明的概述进行说明。
用于解决课题的技术方案
本发明的车辆动力辅助系统用于下述车辆2，该车辆2具有从动轮4，该从动轮4从机械方面来说不与进行驱动轮3的行驶驱动的主驱动源5连接，其中，在支承上述从动轮4的车轮用轴承31上，装载行驶辅助用的电动发电机8，该行驶辅助用的电动发电机8通过借助该从动轮4的旋转而进行发电且供电，由此可旋转驱动上述从动轮4，在上述电动发电机8中，转子42在不夹设增减速机构的情况下固定于上述车轮用轴承31的旋转侧圈上，另外包括蓄电机构，该蓄电机构积蓄上述电动发电机8发出的再生电力，将该已积蓄的电力供给上述电动发电机8。另外，上述从动轮4通过上述电动发电机8而驱动，但是其仅仅为辅助的驱动，从机械方面来说因不与主驱动源5连接，称为从动轮。上述主驱动源5既可仅仅为内燃机，或为内燃机5和电动机的并用，也可仅仅为电动机。
按照该方案，由于包括通过从动轮4的旋转而进行发电的电动发电机8，故可将目前通过机械式制动器进行热变换的能量，将电动发电机8作为发电机，在上述电池中积蓄再生电力，由此可产生制动力。通过与机械式制动器的并用、分开使用，还可提高制动性能。
另外，通过与车辆2的车速、行驶阻力等的行驶状态一起地驱动电动发电机8，可按照形成效率良好的转数·转矩的方式驱动主驱动源5，可提高行驶性能。比如，在加速时，进行电动发电机8的驱动力辅助，或在恒速行驶、常速行驶状态，起电动发电机8的驱动力的附加或发电的作用，由此，可以良好的效率而驱动主驱动源5，另外获得适合的再生电力。特别是，在上述主驱动源5包括内燃机(汽油发动机、柴油发动机)的场合，转数、转矩的效率的不同变大，进行上述电动发电机8的驱动力辅助的主驱动源5的效率提高的效果变大。
上述电动发电机8为下述的直接驱动类型，其装载于车轮用轴承31上，其转子42在不夹设增减速机构的情况下固定于车轮用轴承31的旋转侧圈上，故离合器、动力分配机构、驱动轴等是不需要的，用于提供辅助电力的结构简单即可，还抑制车辆的重量的增加。像这样，可提高行驶性能、制动性能、燃料消耗量等的车辆性能，而且用于提供辅助电力的结构简单即可。
还可在本发明中，在上述车辆2中，在多个从动轮4上设置上述电动发电机8，分别在各从动轮4中设置多个单独控制机构9，该单独控制机构9控制上述电动发电机8。在该方案的场合，在行驶变道等用的加速时、转弯时，通过分别控制电动发电机8，更加稳定的行驶是可能的。
还可在该方案的场合，在进行上述车辆2的综合控制的高级ECU 10中，设置单独电动发电机指令机构15，该单独电动发电机指令机构15向上述各电动发电机8的上述单独控制机构9输出进行驱动和再生的控制的指令。通过在高级ECU 10中设置上述单独电动发电机指令机构15，分别采用各电动发电机8，容易进行上述行驶变道或转弯的支持的控制。
也可在本发明中，上述车辆2包括低电压电池20和中等电压电池19，该低电压电池20构成进行上述车辆的综合控制的高级ECU 10的电源，该中等电压电池19的蓄电电压高于该低电压电池20，该中等电压电池19用作附属部件的电源，与上述电动发电机8连接的上述蓄电机构为上述中等电压电池19。
在驱动车辆的附属部件的场合，在电压高的场合，电流小即可，在布线的粗度、覆盖等的方面，布线上优选。但是，从可靠性的方面来说，最好高级ECU 10等的基本电子部件采用长年使用的12V电池。另外，如果电池的电压过高，则具有进行维修时的触电的问题。由此，从布线方面，可靠性确保的两个方面来说，最好包括独立于构成高级ECU 10的电源的12V的低电压电池20的中等电压电池19，用作基本电子部件以外的电气辅机类的电源。在具有这样的中等电压电池19的场合，从布线等的方面来说，最好，在上述行驶辅助用的电动发电机8用于再生发电、驱动的电源采用上述中等电压电池19。另外，在本说明书中，“附属部件”指车辆的电气部件中的除了作为对于行驶来说必须要求的部件的基本部件以外的部件。
还可在本发明中，上述车辆动力辅助系统包括：低电压电池20，该低电压电池20对低电压负荷22进行供电；中等电压电池19，该中等电压电池19的蓄电电压高于上述低电压电池20，对中等电压负荷23进行供电，该中等电压负荷23的负荷电压高于上述低电压负荷22；转换器21，该转换器21将上述低电压电池20和中等电压电池19连接，上述电动发电机8与上述中等电压电池19电连接，通过上述从动轮4的旋转进行再生，对上述中等电压电池19进行供电，并且通过来自中等电压电池19的供电，旋转驱动上述从动轮4。
同样通过该方案，与前述相同，可进行从动轮4的驱动辅助、再生制动、发电，可提高行驶性能、制动性能、燃料消耗量等的车辆性能，并且用于获得辅助驱动力的结构简单，还可抑制车辆的重量的增加。另外，在该方案的场合，由于独立于低电压电池20而设置中等电压电池19，低电压负荷22通过低电压电池20而进行供电，中等电压负荷23通过中等电压电池19而进行供电，故对应于装载于车辆上的部件，分开地形成低电压的部件、中等电压部件。与上述相同，布线面以及可靠性确保的方面优良。
还可在本发明中，上述电动发电机8可收纳于制动钳37和上述车轮用轴承31的外圈32之间的径向范围内，该制动钳37与安装于上述车轮用轴承31的上述旋转圈上的制动盘36的外周部接触。如果行驶辅助用的电动发电机8为收纳于制动钳37和车轮用轴承31之间的容积，则可仅仅通过转向节部的改造，简单地安装于过去类型的车辆的从动轮上，另外可不管车的种类而安装。
权利要求书和/或说明书和/或附图中公开的至少2个结构中的任意的组合均包含在本发明中。特别是，权利要求书中的各项权利要求的2个以上的任意的组合也包含在本发明中。
附图说明

图2为装载该辅助或车轮从动轮再生系统的车辆的一个例子的电源系统图；
图3为表示装载该车辆动力辅助系统或车轮从动轮再生系统中的电动发电机的从动轮和其下部的纵向剖视图；

图5为通过与轴向相垂直的平面剖开而观看该发电机的放大剖视图(沿图3中的V—V线的剖视图)。
具体实施方式
根据图1～图5，对本发明的一个实施方式进行说明。该车辆动力辅助系统1在具有作为前轮驱动或后轮驱动等的非驱动轮的从动轮4的车辆2中，装载于从机械方面来说不与主驱动源5连接的从动轮4上。主驱动源5为汽油发动机或柴油发动机等的内燃机，或电动发电机(电动机)、或由该两者组合成的混合型的驱动源。另外，“电动发电机”称为可进行旋转施加造成的发电的电动机。在图示的例子中，车辆2为，前轮为驱动轮3，后轮为从动轮4的前轮驱动车，其属于由主驱动源5为内燃机5a的驱动源侧的电动发电机5b构成的混合动力车(在下面称为“HEV”)。具体来说，驱动轮侧的电动发电机5b为通过48V等的中等电压而驱动的微混合动力。
混合动力大致分为强混合动力和微混合动力，但是，强混合动力与微混合动力的区别在于，主要驱动源为内燃机，在出发时、加速时等通过电动机主要进行行驶的辅助的类型，即使在EV(电动汽车)模式的场合暂时进行通常的行驶的情况下，也无法长时间进行，此点与强混合动力相区别。该图的例子的内燃机5a通过离合器6和减速器7，与驱动轮3的驱动轴连接，上述驱动轮侧的电动发电机5b与上述减速器7连接。
车辆动力辅助系统1包括：行驶辅助用的电动发电机8，该行驶辅助用的电动发电机8进行从动轮4的旋转驱动；单独控制机构9，该单独控制机构9进行该电动发电机8的控制；单独电动发电机指令机构15，该单独电动发电机指令机构15设置于高级ECU 10上，将进行驱动和再生的控制的指令输出给上述单独控制机构9。上述电动发电机8与蓄电机构连接。该蓄电机构可采用电池(蓄电池)、电容器、电容等，对于其类型、在车辆上的装载位置，是没有关系的，但是，在本实施方式中，采用装载于车辆2上的低等电压电池20和中等电压电池19。
从动轮用的电动发电机8为没有采用变速器的直接驱动电动机，其通过供给电力，用作电动机，另外还用作将车辆2的运动能量变换为电力的发电机。
图3、图4表示装载上述电动发电机8的从动轮4。上述电动发电机8设置于支承从动轮4的车轮用轴承(也称为“轮毂轴承”)31和制动器35的制动钳37之间。车轮用轴承31按照在构成固定轮的外圈32和构成轮毂圈的内圈33之间设置多排的滚动体34的方式构成，外圈32通过螺栓而紧固于转向节部等的下部支架部件39上。内圈33具有轮毂法兰33a，其以从动轮4的轮4a和上述制动器35的制动盘36重合的方式，通过螺栓40而固定于该法兰33a上。轮4a包括安装于上述内圈33上的圆板状部分4aa、和从其外周延伸到车辆内侧的锥状的圆筒状部4ab，在该圆筒状部4ab上安装轮胎4b。上述车轮用轴承31的整体收纳于轮4a的轴向宽度内。
制动盘36为盘型，其由圆板状部分36a、中间圆板状部分36b与外径侧圆板状部36c构成，该圆板状部分36a安装于上述内圈33上，该中间圆板状部分36b按照从其外周缘包围车轮用轴承31的外周的一部分的方式延伸，该外径侧圆板状部36c从其前端延伸到外径侧，该外径侧圆板状部36c通过由上述制动钳37而开闭的一对制动垫37a、37b夹持。制动钳37也可为液压式和机械式中的任意者，另外还可为电动机。制动钳37安装于上述下部支架部件39上。
像图3～图5所示的那样，电动发电机8由内周侧的环状的定子41和位于其外周的环状的转子42构成，定子41通过嵌合而固定于车轮用轴承31的外圈32上，另外通过螺栓的紧固而一体地固定。定子41和转子42以简化方式进行图示，在本例子中，电动发电机8为IPM电动机等的同步电动机，定子41由定子磁芯41a和定子线圈41b构成。在定子磁芯41a的各齿上，卷绕有定子线圈41b。转子42由磁性体42a和永久磁铁42b构成。转子42在轴向的一端，通过安装部件43借助嵌合或紧固等方式，以固定状态而固定于作为轮毂圈的内圈33的法兰部33a上。转子42的轴向的一部分收纳于制动盘36的上述中间圆筒状部36b上。
由于在上述电动发电机8中，转子42安装于作为轮毂圈的内圈33上，故如果从中等电压电池19对电动发电机8施加电流(供电)，则对内圈33进行旋转驱动，相反地，在电力再生时，通过负荷感应电压可获得再生电力，可对中等电压电池19进行供电。
由于上述电动发电机8设置于车轮用轴承31的外周和制动钳37之间，更具体地说，设置于制动盘36的中间圆筒状部36b之间，故在装载于车辆2上时，不必要求从动轮周边的衰减器等的结构的变更。另外，同样对于车轮用轴承31，外圈32以外的内圈33等的结构部件可沿用已有部件。此外，对于图示的车轮用轴承31，其是针对内圈旋转型的第3代的适用例子而给出的，但是，也可适用于外圈旋转型、第1、第2代等的车轮用轴承。另外，图示的电动发电机8为外转子型的IPM电动机，但是也可为内转子型。另外，电动发电机8可为SPM电动机、IM、SR电动机等的各种电动机。线圈也可为分布卷、集中卷的任意者。
在上述车轮用轴承31中，在内圈33的轮毂法兰部33a和外圈32之间，设置旋转检测器45。该旋转检测器45由编码部45a和传感部45b构成，该编码部45a设置于内圈33上，该传感部45b设置于外圈32上，对上述编码部45a进行读取处理。对于该旋转检测器45，旋转角传感器、霍耳元件、光学式、磁式等，其类型和装载位置是没有关系的。
结合图1，对车辆2的控制系统进行说明。高级ECU 10为进行车辆2的综合控制的机构，在其中，设置按照从加速踏板等的加速操作机构46和制动踏板等的制动操作机构47而分别输入的操作量的信号，形成转矩指令的转矩指令机构13。由于该车辆2包括作为主驱动源5的内燃机5a和驱动轮侧的电动发动机5b，另外，包括分别驱动2个从动轮4、4的2个电动发电机8、8，故在高级ECU 10中设置转矩指令分配机构14，该转矩指令分配机构14按照在上述各驱动源5a、5b和8、8中确定的规则，分配上述转矩指令。对内燃机5a的转矩指令传递给内燃机控制机构17，通过内燃机控制机构17，用于阀打开度控制等。针对驱动轮侧的电动发电机5b的转矩指令传递给驱动轮侧电动发电机控制机构18而执行。针对从动轮侧的电动发电机8、8的转矩指令传递给上述单独控制机构9、9。上述转矩指令分配机构14中的向单独控制机构9、9进行输出的部分称为单独电动发电机指令机构15。该单独电动发电机指令机构15还具有下述的功能，该功能指，相对制动操作机构47的操作量的信号，将构成电动发电机8通过再生制动而分担制动的制动力的指令的转矩指令提供给单独控制机构9。
单独控制机构9为逆变装置，其包括：逆变器11，该逆变器11将中等电压电池19的直流电变换为3相的交流电；控制部12，该控制部12根据上述转矩指令等，通过PWM控制等，控制逆变器11的输出。逆变器11包括半导体开关元件等的桥接电路(在图中没有示出)与充电电路(在图中没有示出)，该充电电路将电动发电机8的再生电力充电到中等电压电池19中。另外，单独控制机构9相对2个电动发电机8、8而分别地设置，但是也可为单独控制机构9收纳于一个外壳内部，2个单独控制机构9、9共用控制部12的结构。
图2为图1所示的(微)混合动力车的电气系统图。在图2的例子中，设置作为电池的低电压电池20和中等电压电池19。2个电池19、20经由DC/DC转换器21而连接。电动发电机8为2个，但是作为代表，在图中仅仅示出1个。另外，图1的驱动轮侧的电动发电机5b与从动轮侧的电动发电机8并列地与中等电力系统连接，虽然关于这一点的图2的图示省略。在低电压系统上连接低电压负荷22，在中等电力系统上连接中等电压负荷23。低电压负荷22和中等电压负荷23分别具有多个，但是在图2中，作为代表仅仅示出1个。
低电压电池20为作为控制系统等的电压而一般用于各种汽车的电池，其电压比如为12V或24V。作为低电压负荷22，包括有内燃机5a的起动电动机、灯类、高级ECU 10或其它的ECU(在图中没有示出)等的核心部件。低电压电池20为电气辅机类用的辅助电池，中等电压电池19为电动系统用的辅助电池等。
中等电压电池19的电压高于低电压电池20，并且其电压低于用于强混合动力车的高压电池(100V以上，比如在200～400V的范围内)，并且为在作业时没有触电对人体的影响的问题的电压，中等电压电池19最好为用于强混合动力的48V电池。48V电池等的中等电压电池19可较容易地装载于过去的装载有内燃机的车辆上。由此，作为微混合动力系统，通过电力的动力辅助、再生，可降低耗油量。
上述48V系统的中等电压负荷23为上述附属部件，其为其电压高于低电压负荷22的负荷。上述48V系统的中等电压负荷23为作为上述驱动轮侧的电动发电机5b的动力辅助电动机、以及其它的电动泵、电动动力操纵机构、超级充电器、空气压缩机等。虽然通过借助48V系统而构成附属部件的负荷，动力辅助的输出低于高电压(100V以上的强混合动力车等)，但是可对乘客、维修作业人员的触电的危险性较低。由于减小电线的绝缘膜的厚度，故可减少电线的重量、体积。另外，由于可以小于12V的电流量输入输出大的电力量，故可减少电动机、发电机的体积。由于这些原因，有助于车辆耗油量降低的效果。
该车辆动力辅助系统适合于这样的微混合动力车的附属部件，适合用作动力辅助器、电力再生产部件。另外，与过去相比较，在微混合动力车中，在内燃机和传动装置之间、齿轮箱和后差速器之间装载电动发电机或(称为CMG，GMG)，在内燃机上直接装载皮带驱动式起动电动机(均在图中没有示出)，但是由于它们均针对内燃机或动力装置，进行动力辅助、再生，故受到传动装置、减速器等的效果的影响。由于相对该情况，该车辆动力辅助系统1装载于从动轮4上，故内燃机5b或电动机(在图中没有示出)等的主驱动源切断开，可在电力再生时，通过从动轮4的旋转进行再生，由此，直接地利用车身1的运动能量。
另外，在于从内燃机5b到轮胎的动力传递部之间，装载电动发电机8时，必须要求从车辆2的设计阶段而进行考虑，进行组装，后加装这一点是困难的。收纳于从动轮4的内部的该车辆动力辅助系统1的电动发电机8即使为成品车的情况下，仍可以与部件更换相同的工时而进行安装，即使相对仅仅内燃机5b的成品车，仍可构成48V的系统。另外，还可在装载该车辆动力辅助系统1的车辆中，像图1的例子那样，装载另外的辅助驱动用的电动发电机5b。此时，可增加车辆2的动力辅助量、再生电力量，另外有助于耗油量的降低。
对上述结构的车辆动力辅助系统1的动作和作用效果进行整理，在下面给出。
(1)制动时
针对到目前通过机械式制动器而进行热变换的能量，将电动发电机8用作发电机，在与电动发电机8电连接的上述中等电压电池19中积蓄电力。由此，产生制动力，可回收到目前的废弃的能量。
(2)加速、稳定行驶时
在主驱动源5具有内燃机(发动机)5a的车辆2的场合，按照与车辆2的行驶状态(车速、行驶阻力等)一起形成发动机效率良好的转数·转矩的方式驱动电动发电机8。由此，发动机效率良好，可有助于耗油量的改善。比如，可在加速时在电动发电机8的驱动力辅助、恒速行驶、常速行驶状态，实现驱动力的附加或发电作用。
(3)行驶性能的提高
在变道用的加速时、转弯时，由于分别控制电动发电机8，故可进行更加稳定的行驶。
(4)低摩擦路面的行驶
在雨天时、雪道等的低摩擦路面的出发，停止时，通过电动发电机8控制轮胎的牵引力，可进行稳定的行驶。由于在接近路面的车轮4b内部具有电动发电机8，故获得响应性良好的操作性。由于具有旋转检测器45(参照图3)，故可省略车载的制动传感器等。
(5)安装性
在过去的普通的内燃机驱动的汽车中，采用通过下部支架部件39的简单的设计变更，安装于下部支架部件39上的简单安装方法。
另外，在上述实施方式中，对适用于混合动力车的场合进行了说明，但是，本发明还可适用于主驱动源5仅仅为内燃机的车辆、或主驱动源5仅仅为电动机的车辆。
在上述实施方式中，给出下述的例子，其中，车辆动力辅助系统1包括电动发电机8，电动发电机8通过从动轮4的旋转进行发电，并且通过供电，旋转驱动电动发电机8。但是，作为车辆动力辅助系统1的变形例子，具有进行发电的功能，但是也可形成不进行供电的旋转驱动的车辆从动轮再生系统1。
即，像图1～图3所示的那样，对于该车辆从动轮再生系统1，在包括从机械方面来说不与进行驱动轮3的行驶驱动的主驱动源5连接的从动轮4的车辆2中，从动轮4通过车轮用轴承31而进行支承，在车轮用轴承31上装载通过从动轮4的旋转而进行发电的发电机8。在该发电机8中，转子42在没有夹设增减速机构的情况下固定于车轮用轴承31的内圈(旋转侧圈)33上，包括积蓄发电机8所发出的再生电力的中等电压电池(蓄电机构)19。
即使为这样的方案，与上述实施方式相同，仍可回收到目前废弃的能量。即，通过将发电机8所发出的再生电力积蓄于中等电压电池19中，可产生制动力。通过与机械式的制动器35的并用、分开使用，还可提高制动性能。
由于在从动轮用的轴承用轴承31上装载发电机8，故容易确保装载发电机8的空间，可在不大大地对已有的车轮用轴承的设计进行变形的情况下设置发电机8。由此，可提高车辆从动轮再生系统1的通用性。
由于发电机8为直接驱动型，其装载于轴承用轴承31上，其转子42不经由增减速机构而固定于轴承用轴承31的内圈(旋转侧圈)33上，故离合器、动力分配机构、驱动轴等是不需要的。由此，可谋求部件数量的降低，使结构简化，还可抑制车辆的重量的增加。由于可简化结构，故谋求成本的降低。另外，由于可抑制车辆的重量的增加，故可抑制燃料消耗量。
在限定于像这样而进行发电的功能的场合，单独控制机构9不为逆变装置，而可作为AC/DC转换装置(在图中没有示出)而构成。上述AC/DC转换装置具有通过将3相交流电变换为直流电压，将发电机8的再生电力充电给中等电压电池19的功能，如果与逆变器相比较，控制方法简单，可小型化。另外，上述实施方式的电动发电机8仅仅用于发电，在此场合，也可将电动发电机8表述为发电机8。
以上，对用于实施本发明的方式进行了说明，但是，在这里公开的实施方式在全部的方面是列举性的，没有限制性。本发明的范围不通过上述的说明，而通过权利要求书而给出，打算包括与权利要求书等同的意思和范围内的全部的变更。
另外，上述实施方式包括下述的形态1、2。即，
(形态1)
形态1涉及辅助车辆的动力的车辆动力辅助系统，其包括：低电压电池，该低电压电池对低电压负荷进行供电；中等电压电池，该中等电压电池的蓄电电压高于上述低电压电池，对中等电压负荷进行供电，该中等电压负荷具有高于上述低电压负荷的电压；转换器，该转换器将上述低电压电池和上述中等电压电池连接；电动发电机，该电动发电机设置于上述车辆的从动轮的车轮用轴承上，与上述中等电压电池电连接，上述电动发电机通过上述从动轮的旋转进行再生，对该中等电压电池进行供电，并且通过来自该中等电压电池的供电，旋转驱动上述从动轮。
按照该形态1，与上述实施方式相同，可进行从动轮的驱动辅助、再生制动、发电，可提高行驶性能、制动性能、燃料消耗量等的车辆性能，并且用于获得辅助气动力的结构简单，还可抑制车辆的重量的增加。另外，在该形态1的方案的场合，由于独立于低电压电池而设置中等电压电池，低电压负荷通过低电压电池而进行供电，中等电压负荷通过中等电压电池而进行供电，故可对应于装载于车辆上的部件，对形成低电压的部件，还是形成中等电压部件的情况分开使用，与上述实施方式相同，在布线方面，以及可靠性的确保的方面，是优良的。
(形态2)
形态2涉及具有从机械方面来说不与进行驱动轮的行走驱动的主驱动源连接的从动轮的车辆从动轮再生系统，该从动轮通过车轮用轴承而支承，通过上述从动轮的旋转而进行发电的发电机装载于上述车轮用轴承上，在上述发电机中，转子在不夹设增减速机构的情况下，固定于上述车轮用轴承的旋转侧圈上，包括蓄电机构，该蓄电机构积蓄上述发电机所发出的再生电力。另外，上述主驱动源也可仅仅为内燃机，或内燃机与电动机的并用，还可仅仅为电动机。
按照该形态2，由于具有通过从动轮的旋转而进行发电的发电机，故可回收到目前废弃的能量。即，通过将发电机发出的再生电力积蓄于蓄电机构中，可产生制动力。通过与机械式制动器的并用、分开使用，还可提高制动性能。由于在从动轮用的车轮用轴承上装载发电机，故容易确保装载发电机的空间，可在不大大地对已有的车轮用轴承进行设计变更的情况下，设置发电机。上述发电机为直接驱动型，其装载于车轮用轴承上，该转子在不夹设增减速机构的情况下，固定于车轮用轴承的旋转侧圈上，离合器、动力分配机构、驱动轴等是不需要的。由此，谋求部件数量的降低，使结构简化，还可抑制车辆重量的增加。由于可简化结构，故谋求成本的降低。另外，由于可抑制车辆的重量的增加，故可抑制燃料消耗量。
