Description

混合动力作业机械
技术领域
本发明涉及并用发动机动力和电力的混合动力作业机械。 
背景技术
以作为本发明的优选例的挖掘机为例来说明背景技术。 
挖掘机如图3所示，通过在履带式的下部行进体1上旋转自如地搭载上部旋转体2，并在该上部旋转体2上安装作业附属装置3而构成。 
该作业附属装置3，包括俯仰自如的动臂4、安装在该动臂4的末端的斗杆5、安装在该斗杆5的末端的铲斗6、和作为驱动它们的液压致动器的动臂、斗杆、铲斗各压力缸7、8、9。 
此外，作为使上部旋转体2旋转的旋转用致动器，在液压挖掘机的情况下使用液压马达，在混合动力挖掘机的情况下使用作为电动致动器的旋转电动机。 
在该混合动力挖掘机中，公知有采用所谓的并联方式的驱动形式的挖掘机(参照特开2001-12274号公报)。 
在该方式中，将液压泵以及发挥发电机作用和电动机作用的发电电动机并联到作为共同的动力源的发动机上，一方面借助液压泵驱动液压致动器，一方面借助发电电动机的发电机作用或者蓄电装置驱动旋转电动机。 
此外，蓄电装置借助发电电动机的发电机作用而充电，在适当时候，发电电动机通过该蓄电装置的放电而发挥电动机作用来辅助发动机。 
例如在进行发动机速度传感(ESS)控制的机械中，对应于发动机转速的降低，在泵的马力降低控制之外，还进行控制辅助力的辅助控制。 
此外，有时与该ESS控制无关，在高负荷时，即仅通过发动机无法维持负荷时，通过辅助动作来弥补该不足的部分。 
在这样通过发电电动机进行发动机辅助动作的混合动力挖掘机中，只要满足发动机的转速或负荷等辅助条件，则无条件地进行辅助控制，所以在不需要辅助动作(造成浪费)的情况下，即在由于超负荷等而导致发动机停止了的情况或明显将发生发动机停止的情况(包括燃料用尽) 下，也会继续辅助动作。 
在该情况下，会发生蓄电力的浪费或过放电，不仅从节能的观点出发不优选，而且会导致蓄电装置的寿命降低。 
发明内容
本发明的目的在于提供一种混合动力作业机械，在无需利用发电电动机进行发动机辅助的情况下可使辅助动作自动停止。 
首先，本发明的混合动力作业机械具有以下的基本构成。 
本发明是一种混合动力作业机械，驱动液压致动器的液压泵、与发挥发电机作用和电动机作用的发电电动机被作为共同的动力源的发动机驱动，蓄电装置借助上述发电电动机的发电机作用而充电，并且借助该蓄电装置的电力而驱动发电电动机来发挥辅助发动机的电动机作用，其中，具备控制利用上述发电电动机进行的发动机辅助动作的控制机构、和检测发动机停止或将直接导致发动机停止的运转状态的运转状态检测机构，控制机构，在借助上述运转状态检测机构检测到发动机停止或者将直接导致发动机停止的运转状态时使上述发动机辅助动作停止。 
根据本发明，在检测出发动机停止或者将直接导致发动机停止的运转状态时，借助控制机构使利用发电电动机进行的发动机辅助动作自动停止，所以可防止蓄电力的浪费或过放电，从蓄电装置的寿命或节能的观点出发优选。 
此外，本发明，在上述基本的构成中，优选地，作为运转状态检测机构，具有检测发动机的实际转速的发动机转速检测机构，控制机构求出发动机的目标转速和检测到的发动机实际转速的偏差，当该偏差在被作为会使发动机停止或直接导致发动机停止的值而预先设定的值以上时，使发动机辅助动作停止。该构成的情况下，发动机的目标转速和实际转速的偏差为设定值以上的时候，相当于上述检测到发动机停止或者将直接导致发动机停止的运转状态的时候。 
此外，本发明，在上述基本的构成中，优选地，作为运转状态检测机构而具有检测燃料的剩余量的燃料检测机构，当燃料剩余量在被作为会使发动机停止或直接导致发动机停止的燃料剩余量而预先设定的值以下时，使发动机辅助动作停止。该构成的情况下，燃料剩余量为设定值以下从而由于燃料用尽导致的发动机停止变得很明显的时 候，相当于上述检测到发动机停止或者将直接导致发动机停止的运转状态的时候。 
附图说明
图1是表示本发明的实施方式的模块构成图。 
图2是用于说明实施方式的作用的流程图。 
图3是作为本发明的优选例的挖掘机的概要侧视图。 
具体实施方式
借助图1、2说明本发明的实施方式。 
图1表示实施方式的混合动力挖掘机的模块构成。 
如该图所示，经由动力分配装置(动力分配器)11而在发动机10上并联连接可变容量型的液压泵12、和发挥发电机作用和电动机作用的发电电动机13，它们由发动机10驱动。 
在液压泵12上连接液压回路14，除图3的动臂压力缸7以外的液压致动器(统一标注附图标记15)由来自液压泵12的液压油驱动。另外，在图1中，表示仅连接一台液压泵12的情况，但有时也并联多台。 
来自发电电动机13的电力经由发电电动机控制器16以及电动机控制器17而送到旋转电动机18，该旋转电动机18的回转力经由减速器19而传递到图3的上部旋转体2，该旋转体2旋转。 
另一方面，在发电电动机13上，经由发电电动机控制器16连接作为蓄电装置的蓄电池(例如锂离子蓄电器)20，成为旋转电动机18的第2动力源。 
该蓄电池20借助发电电动机13的发电机作用而被充电，在适当的时候，发电电动机13借助该蓄电池20的放电力而发挥电动机作用来辅助发动机。 
例如，在进行ESS控制的混合动力挖掘机的情况下，与发动机10的转速降低对应地，在泵马力降低控制的基础上进行该发动机辅助动作。 
发电电动机控制器16，切换发电电动机13的发电机作用和电动机作用，控制发电电力、以及作为电动机时的电流或者转矩，并且根据发电电动机13的发电机输出的过量或不足而控制蓄电池20的充放电。 
此外，电动机控制器17控制旋转电动机18的电流或者转矩。 
作为对利用蓄电池20以及发电电动机13实现的发动机辅助动作进行控制的控制机构，设置发动机转速设定机构21、发动机转速检测机构22、辅助动作实施/停止判断机构23、发电电动机控制机构24。 
发动机转速设定机构21，根据油门25的操作量而设定发动机目标转速，并将其送到辅助动作实施/停止判断机构23。 
发动机转速检测机构22，根据来自发动机转速传感器26的信号而检测(计算)出发动机10的实际转速，并将该值输送到辅助动作实施/停止判断机构23中。 
辅助动作实施/停止判断机构23，求得输入的发动机目标转速和实际转速的偏差，并根据该偏差是否在被作为会使发动机停止或直接导致发动机停止的值而预先设定的值以上，判断辅助动作的实施/停止，并将作为该判断结果的信号输送到发电电动机控制机构24。 
发电电动机控制机构24，若被输入辅助动作实施的信号，则向发电电动机控制器16输出用于发动机辅助的发电电动机转矩指令，而若被输入辅助动作停止的信号，则向发电电动机控制器16输出转矩指令0。 
此外，向辅助动作实施/停止判断机构23输入来自检测发动机燃料的剩余量的燃料传感器27的信号，当燃料剩余量变成被作为直接导致发动机停止的量而预先设定的值以下时，在该机构23中进行辅助动作停止的判断。 
借助图2进一步说明这一点的作用。 
在步骤S1中读入发动机实际转速ω2以及燃料剩余量Fv，在步骤S2中计算发动机目标转速ω1和发动机实际转速ω2的偏差Δω。 
在步骤S 3中，比较该偏差Δω和设定值Δωs，在“否”(Δω＜Δωs)时，在步骤S4中进一步进行燃料剩余量的检测值Fv和设定值Fvs的比较。 
在此，在Fv＞Fvs时(“否”时＝燃料剩余量足够时)，判断为不是发动机停止或者将直接导致发动机停止的状态，而在步骤S5中判断为继续实施辅助动作，继续向图1的发电电动机控制机构24送出辅助动作信号。 
与之相对，在步骤S3中为“是”(Δω≥Δωs)时，以及在步骤S4中为“是”(Fv≤Fvs)时，判断为处于发动机停止或者将直接导致发动机停止的状态而在步骤S6中判断辅助动作停止，并向图1的发电电动机控制机构24发送辅助动作停止信号作为转矩指令0。 
通过该控制，在发动机停止或将直接导致发动机停止的情况下，使发电电动机13进行的发动机辅助动作自动停止，所以可防止蓄电池蓄电力的浪费或过放电，从蓄电池寿命以及节能的观点出发优选。 
另外，作为将直接导致发动机停止的运转状态变化，也可检测泵压力上升到设定值以上的情况或发动机的过热(发动机温度)。 
虽然参照附图和优选实施方式对本发明进行了描述，但显然可以在不脱离本发明权利要求的范围内进行等同替换。
