驱动系统100有利地配置在前轮驱动布置中，以在多种可选模式之一中操作，例如包括但不限于仅发动机驱动模式、纯电驱动模式、再生制动模式和发动机/电辅助模式。当PTU93的输出构件99与联接到后轮(未示出)的第二差速齿轮组(未示出)联接时，驱动系统100的这种配置还能够进行全轮驱动(AWD)操作。替换地，驱动系统100可以被配置为后轮驱动系统。本文所述的驱动系统100有利地使用变矩器50，其实现改进的驾驶性能。此外，驱动系统100配置为提供混合动力推进系统，其中电机30联接到变速器61和差速齿轮组92之间的齿轮系60。此外，混合动力部件能够利用现有的结构安装件和功率传输接口。此外，断开离合器24可以整合到变矩器50的壳体中，从而有助于再生制动模式和惯性滑行，有助于在电动驱动模式中的操作，并且增强油门关闭下的滑行和航行。在一个实施例中(如图所示)，断开离合器24配置为在启用时将发动机曲轴12联接到变矩器50的泵部分56。替换地(未示出)，断开离合器24可以被配置为在启用时将变矩器50的叶轮58联接到变速器61的输入构件51。替换地(未示出)，断开离合器可以被配置为在启用时将变速器61中的中间齿轮(未示出)联接到变速器61的输出构件62。
发动机10优选地配置为通过热力学燃烧过程将燃料转换为机械扭矩的多气缸内燃发动机。发动机10配备有多个促动器和感测装置，用于监测操作和输送燃料，以在气缸中形成燃烧负载(combustion charge)，其能在活塞上产生膨胀力，其中这种力传递到曲轴12，以产生扭矩。发动机10优选地包括起动器20，该起动器包括起动器开关和起动器齿轮22，其中起动器齿轮22啮合地与设置在飞轮14的外周上的齿轮齿接合，所述飞轮在一个实施例中联接到曲轴12。起动器20优选地配置为单相电动机，其包括联接到起动器齿轮22的输出轴，其中单相电动机通过起动器开关的启用而电连接到低压电池78。在一个实施例中，起动器齿轮22与飞轮14永久地啮合。在一个实施例中，飞轮14还联接到输入构件18，该输入构件经由断开离合器24联接到变矩器50的泵部分56。在一个实施例中，断开离合器24是可选择单向离合器。替换地，可以采用任何合适的离合器装置。包括起动开关的发动机10的促动器优选地由发动机控制器控制。

传动系90被设置成经由相应的第一和第二中间驱动轴构件94、95将从变速器61输出的推进功率传递到第一和第二车轮96、97，该第一和第二中间驱动轴构件联接到差速齿轮组92。在一个实施例中，传动系90设置为前轮配置。输入构件91联接到电机30的转子32。第一和第二中间驱动轴构件94、95中的一个(例如第二中间驱动轴构件95)联接到PTU93，如图所示。PTU 93优选地包括能够将扭矩传递到输出构件99的锥齿轮结构98。传动系90可以配置为，在PTU 93联接到第二组车轮时，经由车轮96、97和位于后部位置(未示出)的第二组车轮，在变速器61的输出构件62、电机30、PTU93、和道路表面之间传递牵引功率。驱动系统100是说明性的，并且本文所述的原理适用于类似配置的其它驱动系统。
逆变器模块36配置为具有包括功率晶体管的适当控制电路，例如用于将直流电功率转换成交流电功率并将交流电功率转换为直流电功率的集成栅极双极型晶体管(IGBT)。逆变器模块36优选地对IGBT进行脉宽调制(PWM)控制，以将来自48V电池70的存储直流电功率转换为交流电功率，以驱动电机30，产生转矩。类似地，逆变器模块36将传递到电机30的机械功率转换为直流电功率，以产生可存储在48V电池70中的电能，作为再生制动控制策略的一部分。逆变器模块36从控制器15接收电动机控制命令，并控制逆变器状态，以提供期望的电动机驱动操作或再生制动操作。在一个实施例中，辅助DC/DC电功率转换器76电连接到低压电功率总线，并提供电功率，以通过低压电功率总线对低压电池78充电。这样的电功率连接是可以理解的且在本文没有详细描述。低压电池78向驱动系统100和车辆上的低压系统提供低压电功率，包括例如起动器20、电动窗、HVAC风扇、座椅和其它装置。在一个实施例中，低压电池78被配置为额定12Vdc电压电平工作。
48V电池70优选设置为以额定48Vdc电压电平提供电功率，并且可以是任何直流电源，例如多电池锂离子装置、超电容器或其他合适的装置，而不限于此。与48V电池70相关的监测参数优选包括充电状态(SOC)、温度等。在一个实施例中，48V电池70可以经由车载电池充电器电连接到远程离车电源，以在车辆静止时进行充电。
控制器15可以信号地连接到操作员接口(未示出)，并且操作以提供多个控制装置的分级控制，以实现对驱动系统100的各个元件的操作控制，包括例如逆变器模块36、发动机控制器和变速器控制器。控制器15直接或经由通信总线16与逆变器模块36、发动机控制器和变速器控制器中的每一个进行通信，以监测其操作和控制操作。
