Description

混合动力车辆及其控制方法
技术领域
本发明涉及混合动力车辆及其控制方法,更详细而言,涉及促进混合动力***的起动的混合动力车辆及其控制方法。
背景技术
近年来,从燃料经济性提高及环境对策等观点来看,包括混合动力***的混合动力车辆(以下称为“HEV”)备受瞩目,该混合动力***具有根据车辆的运转状态而被复合性地控制的引擎及电动发电机。在该HEV中,一方面在车辆加速时或起步时,由电动发电机辅助产生驱动力,另一方面在惯性行驶时或制动时,由电动发电机进行再生发电(例如,参照专利文献1)。
在电动发电机上,电连接有逆变器、高电压电池、DC/DC转换器及低电压电池。在混合动力***起动时,虽然会开启被内置于高电压电池的继电器,并开始对逆变器的电力供给,但是为了防止因较大的冲击电力流动到被内置于逆变器的电容器而导致的继电器的破损,需要进行事先对电容器充电来抑制冲击电流的预充电。
因此,因为混合动力***的起动需要时间,所以在HEV起步时,会存在给驾驶员带来迟滞感这样的问题。

发明内容
发明要解决的课题
本发明的目的在于提供一种能够促进混合动力***的起动的混合动力车辆及其控制方法。
用于解决课题的手段
达成上述目的的本发明的混合动力车辆包括:混合动力***,其具有被连接在传递引擎的动力的输出轴上的电动发电机;内置有电容器的逆变器、高电压电池、DC/DC转换器及低电压电池,其被依次电连接在上述电动发电机上;锁定机构,其设定及解除驾驶员席的门锁;以及控制装置;在上述混合动力车辆中,其特征在于,上述控制装置被构成为进行如下控制:在上述引擎停止时,在由上述锁定机构解除了上述门锁时,通过上述DC/DC转换器,从上述低电压电池向上述电容器供电,从而对该电容器进行充电。
此外,一种达成上述目的的本发明的混合动力车辆的控制方法,该混合动力车辆包括:混合动力***,其具有被连接在传递引擎的动力的输出轴上的电动发电机;内置有电容器的逆变器、高电压电池、DC/DC转换器及低电压电池,其依次被电连接在上述电动发电机上;以及锁定机构,其设定并解除驾驶员席的门锁;该控制方法的特征在于,确认上述引擎是否停止,在上述引擎停止时,判定是否由上述锁定机构解除了上述门锁,在上述门锁被解除时,通过上述DC/DC转换器,从上述低电压电池向上述电容器供电,从而对该电容器进行充电。
发明效果
根据本发明的混合动力车辆及其控制方法,因为使混合动力***起动时的预充电与驾驶员乘上引擎停止的混合动力车辆同时开始,所以能够促进混合动力***的起动。
附图的简要说明
图1是由本公开的实施方式构成的混合动力车辆的构成图。
图2是说明由本公开的实施方式构成的混合动力车辆的控制方法的流程图。
具体实施方式
以下,参照附图说明本发明的实施方式。图1表示由本发明的实施方式构成的混合动力车辆。
该混合动力车辆(以下称为“HEV”)是不仅包含普通乘用车,还包含公共汽车或卡车等的车辆,其包括混合动力***30,该混合动力***30具有根据车辆的运转状态而被复合性地控制的引擎10及电动发电机31。
在引擎10中,利用由燃料在被形成在引擎本体11中的多个(在本例中为4个)汽缸12内燃烧而产生的热能,旋转驱动曲轴13。在该引擎10中,使用了柴油引擎或汽油引擎。曲轴13的旋转动力通过连接在曲轴13的一端部上的离合器14(例如,湿式多片离合器等)而被传递到变速器20。
由变速器20变速后的旋转动力通过驱动轴22而被传递到差动器23,并作为驱动力而被分别分配到一对驱动轮24。
混合动力***30具有:电动发电机31;以及电连接在该电动发电机31上的逆变器35、高电压电池32、DC/DC转换器33及低电压电池34。
作为高电压电池32,例示优选锂电池或镍氢电池等。此外,铅电池被用于低电压电池34。
在逆变器35中,内置有电容器103。DC/DC转换器33具有控制高电压电池32与低电压电池34之间的充放电的方向及输出电压的功能。此外,低电压电池34将电力供给到各种车辆电子产品36。
通过被内置于高电压电池32的继电器(未图示)接通,而开始对逆变器35的电力供给,从而起动该混合动力***30。另外,继电器被设置在高电压电池32的正极侧及/或负极侧。
混合动力***30中的各种参数,例如电流值、电压值或电池的充电状态(State ofCharge;SOC)等由电池管理***(BMS)39来检测。
电动发电机31经由被紧绕在第1带轮15与第2带轮16之间的环状的带状构件17而在与引擎10之间传递动力,上述第1带轮15被安装在旋转轴37上,上述第2带轮16被安装在引擎本体11的输出轴,即曲轴13的另一端部上。另外,也可以不使用2个带轮15、16以及带状构件17,而是使用齿轮箱等来传递动力。此外,引擎本体11的连接在电动发电机31上的输出轴并不限于曲轴13,例如也可以为引擎本体11与变速器20之间的传递轴或驱动轴22。
该电动发电机31也具有代替起动引擎本体11的起动电动机(未图示)来进行起动的功能。
此外,在HEV的驾驶员席的门100上,设置有进行门锁的设定及解除的锁定机构101。该锁定机构101由驾驶员在上车或下车时操作。
引擎10及混合动力***30两者由控制装置80控制。具体而言,一方面在HEV起步时或加速时,混合动力***30通过由高电压电池32供给电力的电动发电机31来辅助产生驱动力的至少一部分,另一方面在惯性行驶时或制动时,由电动发电机31进行再生发电,将剩余的动能转换为电力,从而对高电压电池35进行充电。
作为控制装置80的功能,以下基于图2说明这种HEV的控制方法。另外,控制装置80通过信号线(由单点划线表示)与各部连接。
控制装置80确认引擎10是否停止(S10),在其停止的情况下,判定是否由锁定机构101解除了驾驶员席的门锁(S20)。
接着,控制装置80在门锁被解除时,通过BMS39来检测高电压电池32的状态,例如电压值V(S30)。
然后,控制装置80将由DC/DC转换器33升压后的电力从低电压电池34向逆变器35内的电容器103进行供给,从而对电容器103进行充电,直到成为预先被设定的条件,例如电容器103的电压的大小成为电压值V为止(S40)。
最后,控制装置80接通被内置于高电压电池32的继电器,将电力供给到逆变器35(S50),并使混合动力***30起动(S60)。
如此,因为使混合动力***30起动时的预充电与驾驶员乘上引擎10停止的HEV同时开始,所以是能够促进混合动力***30的起动的。
本申请基于2015年12月3日申请的日本专利申请(特愿2015-236756),并将其内容作为参照援引于此。
