Description

一种混合动力汽车动力系统和发动机起停机减噪方法
技术领域
本发明属于混合动力汽车技术领域，具体涉及一种混合动力汽车动力系统和发动机起停机减噪方法。
背景技术
混合动力汽车有发动机和动力电源两个动力平台，其结构如图1所示，包括发动机1，扭转减震器2，主动端齿轮3，从动端齿轮4，行星架5，太阳轮6，驱动电机7，后桥8，驱动轴9，交直流变换器10，动力电源11，太阳轮12，发电机13和输出轴14。其中发动机1能够通过输出轴14驱动发电机13向动力电源11充电，也能通过驱动轴控制后桥8，为车辆提供动力，动力电源11也能够通过驱动电机7驱动轴控制后桥8，为车辆提供动力。
由于混合动力汽车的机械结构比较复杂，导致发动机在起/停机时产生的振动通过变速箱、发电机和驱动电机等机械结构的联轴振动放大，造成的噪音极大影响了乘客及驾驶员的舒适感。目前采用的方法是通过增加隔音棉的方式来降低噪音，这种方式虽然会减小对声觉影响，但是会增加车辆的制造成本，而且并未从噪声产生的根源来进行本质上的改善。

本发明提供的一种混合动力汽车动力系统和发动机起停机减噪方法，在混合动力汽车的发动机启动或停机时，对驱动电机进行堵转，使发动机的振动不能通过变速箱等机械结构将振动放大，从而降低混合动力汽车发动机在起停机时造成的振动，提高车辆的舒适性。
附图说明
图1为混合动力车辆的混合动力驱动系统结构图；
图2为混合动力汽车发动机起停减噪方法的流程图。
具体实施方式
本发明提供一种混合动力汽车动力系统和发动机起停机减噪方法，不仅适用于采用图1所示结构的混合动力驱动系统的混合动力车辆，也适用于采用其他混合动力驱动系统的车辆，用于降低混合动力汽车发动机起停机时造成的振动。
下面结合附图对本发明进行详细说明。
方法实施例：
本实施例提供一种混合动力汽车发动机起停机减噪方法，其流程如图2所示，包括降低车辆发动机启动时和停机时振动的方法。具体方法如下：
当车辆发动机启动或停机时：以200Nm(或200Nm以下)的扭矩进行正向拖动驱动电机，使驱动电机在整个发动机启动过程产生堵转动作，抑制整个动力系统的末端振动，降低噪音，直到驱动电机的转速达到发动机启动或停机过程所对应的目标转速。
发动机启动过程所对应的目标转速，是指发动起在启动过程中，当达到该转速之后不会再产生较大的振动。
发动机停机过程所对应的目标转速，是指发动起在停机过程中，当达到该转速之后不会再产生较大的振动。
在发动机起动时，需要在驱动电机转速交底时进行堵转，所以在发动机起动开始时就进行堵转。
在发动机停机时，由于惯性发动机依然工作，此时部分能量会传输到发电机进行发电，然后对动力电源进行充电，所以为了对能量进行回收，并进一步的加快对发动机的制动，当驱动电机的转速较大时不堵转，当转速达到堵转开始设定值时再制动。
在本实施例中，将堵转开始设定值设为50rpm，作为其他实施方式，也可以根据发动机的实际工作情况，将其设置为其他值。
在本实施例所提供的一种混合动力汽车发动机起停机减噪方法，在车辆发动机启动或停机，对驱动电机堵转时，如果发生如下情况，则停止堵转：
(1)堵转时间达到时间设定值；
对驱动电机进行堵转时间太长会对驱动电机造成一定的损害，所以不能堵转时间太长，时间设定值最大为3s；
(2)驱动电机转速达到堵转停止设定值；
在对驱动电机堵转时，可能会由于车辆的手刹出现故障(即有信号但手刹机械损坏)而出现不受控的“溜车”现象，使驱动电机的转速加大，在这种情况下，当驱动电机的转速达到堵转停止设定值时，需要停止堵转；堵转停止设定值大于堵转开始设定值，在本实施例中，堵转停止设定值为100rpm；
(3)接收到取消堵转的指令。
当发动机停机时对驱动电机进行堵转，如果接受到取消堵转的指令，可能是控制策略上有所调整，所以需要根据指令停止堵转。
系统实施例：
本实施例所提供一种混合动力汽车动力系统，包括发动机、驱动电机和驱动轴，发动机和驱动电机均传动连接驱动轴。当发动机停机或者启动时，采用上述方式实施例提供的混合动力汽车发动机起停机减噪方法降低振动。上面方法实施例中已经对混合动力汽车发动机起停机减噪方法进行了详细的介绍，这里不多做说明。
以上给出了本发明涉及的具体实施方式，但本发明不局限于所描述的实施方式。在本发明给出的思路下，采用对本领域技术人员而言容易想到的方式对上述实施例中的技术手段进行变换、替换、修改，并且起到的作用与本发明中的相应技术手段基本相同、实现的发明目的也基本相同，这样形成的技术方案是对上述实施例进行微调形成的，这种技术方案仍落入本发明的保护范围内。
