背景技术
通常，混合动力电动车辆一起使用内燃机和电池电源。混合动力电动车辆有效地组合了内燃机的扭矩和马达的扭矩。
根据发动机和马达之间的功率分配比例，混合动力电动车辆可以被分成重度型(hard type)和中度型(mild type)。在中度型混合动力电动车辆(以下称为中度混合动力电动车辆)的情况下，使用被配置为起动发动机或根据发动机的输出产生电力的中度混合动力起动器和发电机(MHSG)，而不是交流发电机。在重度型混合动力电动车辆的情况下，除了被配置为起动发动机或产生电力的集成起动器和发电机(ISG)之外，还采用被配置为用于产生驱动扭矩的驱动马达。
MHSG可以根据车辆的行驶状态辅助发动机的扭矩，并且可以通过再生制对电池(例如，48V电池)充电。因此，可以提高中度混合动力电动车辆的燃料效率。
在中度混合动力电动车辆滑行的状态下，可以阻止从发动机传递到变速器的扭矩，以增加中度混合动力电动车辆的行驶距离。当解除滑行时，发动机的扭矩可被再次传递到变速器。在当前情况下，当发动机的速度不与变速器的输入轴的速度同步时，可能对变速器施加冲击。仅使用发动机的燃烧扭矩使发动机的速度与变速器的输入轴的速度同步需要很长时间。
本发明的背景技术部分中公开的信息仅用于增强对本发明的一般背景的理解，并且不应被视为承认或以任何形式建议该信息形成本领域技术人员已知的现有技术。

在以下详细描述中，将参考附图更完整地描述本申请的示例性实施例，其中示出本发明的示例性实施例。然而，本发明不限于本文描述的示例性实施例，并且可以以各种不同的方式修改。
为了清楚地描述本发明的示例性实施例，省略了与描述无关的部分，并且在整个说明书中相同的附图标记指代相同或相似的元件。
由于为便于描述任意地示出了附图中的每个部件，本发明并不特别限于附图中所示的部件。
图1是根据本发明的示例性实施例的中度混合动力电动车辆的框图。
如图1所示，根据本发明的示例性实施例的中度混合动力电动车辆包括发动机10、变速器20、中度混合起动机和发电机(MHSG)30、电池40、差动齿轮装置50和车轮60。
发动机10燃烧燃料和空气以将化学能转化成机械能。可以控制点火正时、空气量、燃料量和空燃比，以产生发动机10的燃烧扭矩。
参考中度混合动力电动车辆的扭矩传递，从发动机10产生的扭矩被传递到变速器20的输入轴25，并且从变速器20的输出轴27输出的扭矩经由差动齿轮装置50被传递到轴。所述轴旋转车轮60，使得中度混合动力电动车辆通过从发动机10产生的扭矩运行。
变速器20包括换挡离合器21和齿轮系23。换挡离合器21设置在发动机10和齿轮系23之间，并选择性地将发动机10连接到齿轮系23。换句话说，换挡离合器21选择性地将发动机10的扭矩传递到齿轮系23。齿轮系23根据中度混合动力电动车辆的行驶状态改变传动比，以执行到目标挡位的换挡。
MHSG 30将电能转换成机械能或将机械能转换成电能。MHSG30起动发动机10或者根据发动机10的输出来产生电力。另外，MHSG30可以辅助发动机10的扭矩。发动机10的扭矩可以用作主扭矩，并且MHSG 30的扭矩可以用作辅助扭矩。发动机10和MHSG 30可以通过皮带32彼此连接。
电池40可以向MHSG 30供电，并且可以通过由MHSG 30回收的电力来充电。电池40可以是48V电池。中度混合动力电动车辆可进一步包括将从电池40供应的电压转换成低电压的低电压电池DC-DC转换器(LDC)，以及将低电压供应到多个电气负载(例如，头灯和空调)的低电压电池(例如，12V电池)。
图2是示出根据本发明的示例性实施例的用于控制中度混合动力电动车辆的MHSG的装置的框图。
如图3所示，根据本发明的示例性实施例的用于控制中度混合动力电动车辆的MHSG的装置包括数据检测器70和控制器80。
数据检测器70检测用于控制MHSG 30的数据，并且由数据检测器70检测到的数据被发送到控制器80。数据检测器70可以包括加速器踏板位置检测器71、制动踏板位置检测器72、车辆速度检测器73、挡位检测器74、坡度检测器75和发动机速度检测器76。
加速器踏板位置检测器71检测加速器踏板的位置值(即，加速器踏板的推动程度)，并将与其对应的信号发送到控制器80。当加速器踏板被完全推动时，加速器踏板的位置值为100％，并且当加速器踏板未被推动时，加速器踏板的位置值为0％。
制动踏板位置检测器71检测制动踏板的位置值(即，制动踏板的推动程度)，并且将与对应的信号发送到控制器80。当制动踏板被完全推动时，制动踏板的位置值为100％，并且当制动踏板未被推动时，制动踏板的位置值为0％。
车辆速度检测器73检测中度混合动力电动车辆的速度，并且将与其对应的信号发送到控制器80。
挡位检测器74检测当前正在接合的挡位(在下文中，被称为“当前挡位”)，并且向控制器80发送与其对应的信号。例如，可以接合的挡位可以是八速变速器中的第一挡、第二挡、第三挡、第四挡、第五挡、第六挡、第七挡和第八挡以及倒车挡。
坡度检测器75检测道路的坡度，并将与其对应的信号发送到控制器80。
发动机速度检测器76检测发动机10的速度，并将与其对应的信号发送到控制器80。
控制器80基于由数据检测器70检测到的数据来控制MHSG 30的操作。控制器80可以确定是否满足滑行驱动进入条件，并且可以基于数据确定是否满足滑行驱动解除条件。可以通过预定程序执行的一个或多个处理器来实现控制器80，并且预定程序可以包括用于执行根据本发明的示例性实施例的用于控制中度混合动力电动车辆的MHSG的方法中包括的每个步骤的一系列命令，这将在下面描述。
图3是示出根据本发明的示例性实施例的用于控制中度混合动力电动车辆的MHSG的方法的流程图。
如图3所示，根据本发明的示例性实施例的用于控制中度混合动力电动车辆的MHSG的方法开始于步骤S100处检测用于控制MHSG30的数据。加速器踏板位置检测器71检测加速器踏板的位置值，制动踏板位置检测器72检测制动踏板的位置值，车辆速度检测器73检测中度混合动力电动车辆的速度，挡位检测器74检测当前挡位，并且坡度检测器75检测道路的坡度，以及发动机速度检测器76检测发动机10的速度。
在步骤S110，控制器80基于数据确定是否满足滑行驱动进入条件。控制器80可基于加速器踏板的位置值、制动踏板的位置值、中度混合动力电动车辆的速度、当前挡位以及道路的梯度来确定是否满足滑行驱动进入条件。例如，当加速器踏板的位置值是第一预定位置值(例如0％)，制动踏板的位置值是第二预定位置值(例如0％)，中度混合动力电动车辆的速度等于或大于第一预定速度(例如，30KPH)，当前挡位等于或大于预定挡位(例如，第四挡位)，并且道路的坡度在预定坡度范围内(例如-4％和4％之间)时，可满足滑行驱动进入条件。
当在步骤S110中不满足滑行驱动进入条件时，控制器80完成根据本发明的示例性实施例的用于控制中度混合动力电动车辆的MHSG30的方法。
当在步骤S110满足滑行驱动进入条件时，在步骤S120，控制器80解除换挡离合器21。在这种情况下，控制器80停止发动机10或将发动机10维持在空转状态。发动机10的速度在空转状态下可以是800RPM至1000RPM。因此，在发动机10和变速器20之间的连接被阻断的状态下，中度混合动力电动车辆的行驶距离根据滑行驱动增加，从而改善中度混合动力电动车辆的燃料消耗。在中度混合动力电动车辆滑行的状态下，中度混合动力电动车辆的速度可以降低，并且因此可以执行降挡。换句话说，控制器80可以通过使用基于加速器踏板的位置值和中度混合动力电动车辆的速度的换挡模式映射来改变齿轮系23的传动比。在换挡模式映射中设置对应于加速器踏板的位置值和中度混合动力电动车辆的速度的目标挡位。例如，当前挡位为第四挡位，并且中度混合动力电动车辆的速度减小时，可以执行到第三挡位的换挡。
在中度混合动力电动车辆滑行的状态下，控制器80在步骤S130确定是否满足滑行驱动解除条件。控制器80可以基于加速器踏板的位置值、制动踏板的位置值、中度混合动力电动车辆的速度、当前挡位以及道路的坡度来确定是否满足滑行解除条件。例如，当加速器踏板的位置值大于第一预定位置值，制动踏板的位置值大于第二预定位置值，中度混合动力电动车辆的速度小于第二预定速度(例如25KPH)，当前挡位小于预定挡位或者道路的坡度超出预定坡度范围时，可满足滑行解除条件。
当在步骤S130未满足滑行解除条件时，维持中度混合动力电动车辆的滑行。
当在步骤S130满足滑行解除条件时，控制器80在步骤S140确定发动机10的目标速度。在解除换挡离合器21的状态下，发动机10的速度与变速器的输入轴25的速度之间存在差异。换句话说，当解除换挡离合器21并且停止发动机10时，发动机10的速度可以是0RPM，并且当发动机10处于空转状态时，发动机10的速度可以是800RPM到1000RPM。变速器20的输入轴25的速度可以基于中度混合动力电动车辆的速度和当前挡位的传动比来确定。在发动机10的速度与变速器20的输入轴25的速度不同步的状态下，当接合换挡离合器21时，可能发生接合冲击。发动机10的目标速度可以基于加速器踏板的位置值和中度混合动力电动车辆的速度来确定。例如，当驾驶员在滑行期间推动加速器踏板时，可需要从当前挡位换挡到目标挡位，并且控制器80可以基于加速器踏板的位置值和中度混合动力电动车辆的速度确定对应于目标挡位的发动机10的目标速度。
在步骤S150，控制器80可以控制MHSG 30，使得发动机10的速度增加到目标速度。当使用MHSG 30的扭矩来增加发动机10的速度时的时间(例如，大约1.2秒)短于当使用发动机10的燃烧扭矩来增加发动机10的速度时的时间(例如，大约1.6秒)。换句话说，就响应而言，MHSG 30的扭矩控制比通过燃料和空气的燃烧的扭矩控制更快。
在步骤S160，控制器80确定发动机10的速度是否达到目标速度。
当在步骤S160发动机10的速度没有达到目标速度时，控制器80继续执行步骤S150。
当在步骤S160发动机10的速度达到目标速度时，控制器80在步骤S170接合换挡离合器21。因此，发动机10的扭矩可以被传递到变速器20。
如上所述，根据本发明的示例性实施例，可以减少换挡离合器21的接合冲击和接合时间。
