Abstract

本发明提供一种混合动力汽车,运算出表示利用外部充电的程度的利用指标IDX并向车外系统发送(S140)。车外系统基于利用指标IDX来提高服务或征收罚金(S160~S190)。此时,若车外系统在通过利用指标IDX判断为外部充电的利用的程度低时与判断为高时相比提供冷淡的服务或征收重度的罚金,则车辆的驾驶者或所有者会采取将利用指标判断为利用外部充电的程度高的行动。其结果是,能够促进外部充电的利用。

Description

混合动力汽车
技术领域
本发明涉及混合动力汽车,详细而言,涉及进行蓄电池的充电和向燃料罐的供油的混合动力汽车。
背景技术
以往,作为这种混合动力汽车,提出了从对蓄电池进行外部充电起的与基于内燃机的燃料使用量对应的参数的变化达到预定值时限制电动机及内燃机的输出中的至少一方的方案(例如,参照日本特开平8-19114)。在该混合动力汽车中,在参数的变化达到预定值时限制电动机及内燃机的输出的至少一方,由此催促驾驶员进行外部充电,促进不依赖于内燃机的行驶,保留在紧急时能够通过内燃机行驶这样的富余度,并且能够充分地得到电动汽车的本来目的的大气的污染的抑制效果。
然而,在上述混合动力汽车中,仅限制电动机及内燃机的输出中的至少一方的话,有时促进利用外部充电的效果不充分。例如,对于总是以比较低的动力行驶地驾驶的驾驶员来说,电动机或内燃机的输出限制不具有任何意义。
发明内容
本实施例的混合动力汽车包括:
发动机;
燃料罐,向上述发动机供给燃料;
电动机;
蓄电池,向上述电动机供给电力;
充电器,进行使用外部电源对上述蓄电池进行充电的外部充电;及
通信装置,将表示在预定期间内利用上述外部充电的程度的利用指标向车外系统发送。
在本实施例的混合动力汽车中,将表示预定期间内的利用外部充电的程度的利用指标向车外系统发送。车外系统能够基于接收到的利用指标而提供各种服务或征收各种罚金。此时,若车外系统在通过利用指标而判断为利用外部充电的程度低时,与判断为高时相比,提供冷淡的服务或者征收重度的罚金,则车辆的驾驶者或所有者要采取将利用指标判断为利用外部充电的程度高的行动。其结果是,能够促进外部充电的利用。在此,作为“预定期间”,可以使用1个月或2个月那样的按照时间预先确定的期间或20次的行程期间或30次的行程期间那样的按照机会预先确定的期间等。
另外,作为车外系统提供的服务或征收的罚金,可列举例如收费道路的通行费用的多少、是否许可多个车道的道路中的优先车道或专用车道的利用、是否许可停车场等的入场、是否许可停车场中的优先停车地点或专用停车地点的利用、充电站的充电费用的多少等。
上述通信装置(通信控制单元)也可以构成为在上述通信装置接收到来自上述车外系统的通信要求时发送上述利用指标。这样一来,只要仅在从车外系统具有通信要求时发送利用指标即可。
“利用指标”是表示预定期间内的利用外部充电的程度的指标,在本说明书中使用表示越大则越能良好地利用外部充电的关系的指标。例如,可以将以下的(1)~(14)直接用作利用指标,或者可以将基于(1)~(14)中的一个或多个而运算得到的指标用作利用指标。
(1)充电次数相对于行程次数的比率(充电次数/行程次数);
(2)将充电器与外部电源连接的总时间相对于系统关闭而停车的总时间的比率(充电器连接总时间/停车总时间);
(3)EV行驶的总距离相对于HV行驶的总距离的比率(EV行驶总距离/HV行驶总距离);
(4)EV行驶的总时间相对于HV行驶的总时间的比率(EV行驶总时间/HV行驶总时间);
(5)EV行驶的总距离相对于总行驶距离的比率(EV行驶总距离/总行驶距离);
(6)EV行驶的总时间相对于总行驶时间的比率(EV行驶总时间/总行驶时间);
(7)充电器对蓄电池的充电的总充电量相对于向燃料罐供油的总供油量的比率(总充电量/总供油量);
(8)通过来自外部电源的电力对蓄电池充电的能量的累计值相对于行驶消耗的能量的累计值的比率(外部充电能量累计值/行驶消耗能量累计值);
(9)因EV行驶而消耗的能量的累计值相对于因HV行驶而消耗的能量的累计值的比率(EV行驶能量累计值/HV行驶能量累计值);
(10)将充电器与外部电源连接的总时间(充电器连接总时间);
(11)充电器对蓄电池的充电的总充电量;
(12)行驶的总行驶距离相对于二氧化碳的总排出量的比率(总行驶距离/二氧化碳总排出量);
(13)车辆处于能够进行外部充电的状态时进行了外部充电的次数(机会内充电次数)相对于车辆处于能够进行外部充电的状态的充电机会的次数(机会次数)的比率(机会内充电次数/机会次数);
(14)从进行外部充电起的基于内燃机的燃料使用量的倒数(1/外部充电后燃料使用量)。

虽然未图示,但是HVECU70构成为以CPU为中心的微型处理器,除了CPU之外,还具备存储处理程序的ROM和暂时存储数据的RAM、闪存72、输入输出端口、通信端口。来自各种传感器的信号经由输入端口而向HVECU70输入。作为向HVECU70输入的信号,可以列举例如来自点火开关80的点火信号、来自挡位传感器82的挡位SP、来自加速器踏板位置传感器84的加速器开度Acc、来自制动踏板位置传感器86的制动踏板位置BP。而且,能够列举来自车速传感器88的车速V、来自行驶距离计89的行驶距离Lpre、来自安装于燃料罐25的燃料计25a的燃料量Qf。此外,还能够列举来自安装于电源插头61而判定电源插头61是否与外部电源69连接的连接开关62的连接信号SWC、来自导航装置90的数据等。从HVECU70经由输出端口而输出各种控制信号。作为从HVECU70输出的控制信号,能够列举例如向充电器60的控制信号、向安装于驾驶席前方的仪表板的显示装置92的显示控制信号等。HVECU70经由通信装置94而向车外系统发送车辆信息或者从车外系统接收信息。而且,如上所述,HVECU70经由通信端口而与发动机ECU24、电动机ECU40、蓄电池ECU52连接。另外,HVECU70在向燃料罐25供油时基于来自燃料计25a的燃料量Qf来计算供油量Qin。
在这样构成的实施例的混合动力汽车20中,以CD(Charge Depleting:电量消耗)模式或CS(Charge Sustaining:电量保持)模式进行混合动力行驶(HV行驶)或电动行驶(EV行驶)。在此,CD模式是与CS模式相比使EV行驶更优先的模式。HV行驶是伴随着发动机22的运行而行驶的模式。EV行驶是不伴随发动机22的驾驶而行驶的模式。
在实施例中,在自家或充电站等充电点处进行系统关闭(系统停止)而停车时,如果电源插头61与外部电源69连接,则HVECU70以使用来自外部电源69的电力对蓄电池50充电的方式对充电器60进行控制。并且,在系统接通(系统启动)时,在蓄电池50的蓄电比例SOC比阈值Shv1(例如45%、50%、55%等)大时,以CD模式行驶直至蓄电池50的蓄电比例SOC达到阈值Shv2(例如25%、30%、35%等)以下为止,在蓄电池50的蓄电比例SOC达到阈值Shv2以下之后,以CS模式行驶直至系统关闭为止。而且,在系统接通时,在蓄电池50的蓄电比例SOC为阈值Shv1以下时,以CS模式行驶直至系统关闭为止。
接下来,说明这样构成的实施例的混合动力汽车20的动作,尤其是将表示充电器60对蓄电池50的利用充电(外部充电)的程度的利用指标IDX向车外系统发送时的动作。首先,对利用指标IDX进行说明。图2是表示利用指标运算处理程序的一例的流程图。本程序在系统接通(系统启动)时、系统关闭(系统停止)时、在外部电源69连接电源插头61而蓄电池50的充电完成时、向燃料罐25进行了供油时等的预先确定的启动定时执行。以下,假定本程序在系统接通(系统启动)时执行的情况来进行说明。
当执行利用指标运算处理程序时,HVECU70首先执行输入反映为了运算预先确定的预定期间内的利用指标IDX所需的车辆利用状况的数据的处理(步骤S100)。在此,作为“预定期间”,能够使用1个月或2个月那样的按照时间预先确定的期间、或者20次的行程的期间或30次的行程的期间那样的按照机会预先确定的期间等。而且,作为反映车辆利用状况的数据,作为从上次的行程的系统接通的定时至本次的行程的系统接通的定时为止的数据,能够列有无举充电器60对蓄电池50的充电(有无外部充电)、将充电器60的电源插头61与外部电源69连接的充电时间(充电器连接时间)、充电器60对蓄电池50的充电量。而且,能够列举供油量和燃料量Qf、从上次的行程的系统关闭的定时至本次的行程的系统接通为止的停车时间、上次的行程的行驶距离、上次的行程的行驶时间。此外,能够列举上次的行程的EV行驶距离、上次的行程的EV行驶时间、上次的行程的HV行驶距离、上次的行程的HV行驶时间。而且,还能够列举上次的行程中的因EV行驶而消耗的能量(EV行驶能量)、上次的行程中的因HV行驶而消耗的能量(HV行驶能量)、蓄电比例SOC、车辆的当前位置等。
当这样输入为了运算利用指标IDX所需的数据时,使用输入的数据来运算利用指标IDX,并存储于HVECU70的未图示的RAM或闪存72(步骤S110),结束本程序。在实施例中,利用指标IDX被作为以下的(1)~(14)中的任一个而运算,或者基于(1)~(14)中的以个或多个而运算出。另外,利用指标IDX被作为越大则充电器60对蓄电池50的充电(外部充电)的利用越良好地进行的利用指标而算出。

接下来,说明将利用指标IDX向车外系统发送时的动作。为了便于说明,使用以下的具体例进行说明。作为具体例,作为车外系统,是电子费用收受系统(Electronic TollCollection System:ETC),作为其费用区分,假定为费用最优惠的“电动汽车”、第二优惠的“插电式混合动力汽车”、通常费用的“一般汽车”这三种。而且,实施例的混合动力汽车20搭载有ETC车载器,ETC车载器兼用作通信装置94。图3是表示作为车辆侧的ETC车载器发挥作用的通信装置94与作为电子费用收受系统发挥作用的车外系统的通信的流程的一例的说明图。
在实施例的混合动力汽车20要通过ETC门时,作为电子费用收受系统发挥作用的车外系统对行驶车辆进行识别(步骤S100),向混合动力汽车20侧发送通信要求(步骤S110)。作为ETC车载器发挥作用的通信装置94当接收到来自车外系统的通信要求时(步骤S120),从HVECU70取得利用指标IDX(步骤S130),将车辆信息和利用指标IDX向车外系统侧发送(步骤S140)。
车外系统当接收到车辆信息和利用指标IDX时(步骤S150),基于车辆信息来判别混合动力汽车20的车辆种类(步骤S160)。当判别为车辆种类为电动汽车(EV车辆)时,设定为适用最优惠的低额的EV通行费用(步骤S180)。当判别为车辆种类为不是电动汽车(EV车辆)或插座式混合动力汽车(PHV车辆)的一般车辆时,设定为适用不优惠的比较高额的一般车辆用的一般通行费用(步骤S190)。当判别为车辆种类为插座式混合动力汽车(PHV车辆)时,对利用指标IDX与阈值Iref进行比较(步骤S170)。在此,阈值Iref被预先设定为认为外部充电的利用的程度比较低的值。在利用指标IDX为阈值Iref以上时,判断为利用外部充电的程度高或比较高,设定为适用EV通行费用与一般通行费用的中间的PHV通行费用(步骤S185)。另一方面,在利用指标IDX小于阈值Iref时,判断为利用外部充电的程度低或比较低,设定为适用一般通行费用(步骤S190)。这样设定通行费用后,将设定的通行费用向混合动力汽车20发送(步骤S200)。
通信装置94从车外系统接收到通行费用时(步骤S210),进行接收到的通行费用的支付处理(步骤S220)。该通行费用的支付处理包括“通行费用为○○日元。”等的广播处理或向显示装置92的显示处理。
以上,说明了作为ETC车载器发挥作用的通信装置94与作为电子费用收受系统发挥作用的车外系统之间的利用指标IDX的通信、及基于利用指标IDX的车外系统提供的服务或征收的罚金。基于利用指标IDX的车外系统提供的服务或征收的罚金不限定于这样的电子费用收受系统,例如,可列举是否许可多个车道的道路中的优先车道或专用车道的利用、是否许可停车场等的入场、是否许可停车场中的优先停车地点或专用停车地点的利用、充电站的充电费用的多少等各种。
在以上说明的实施例的混合动力汽车20中,运算出表示利用外部充电的程度的利用指标IDX并向车外系统发送。车外系统基于利用指标IDX来提供服务或征收罚金。此时,如果车外系统在根据利用指标IDX而判断为外部充电的利用的程度低时与判断为高时相比提供冷淡的服务或征收重度的罚金,则车辆的驾驶者或所有者会采取将利用指标判断为利用外部充电的程度高的行动。其结果是,能够促进外部充电的利用。
在实施例的混合动力汽车20中,具备将电源插头61与外部电源69连接而对蓄电池50进行充电的充电器60,但是也可以具备非接触地接受来自外部电源69的电力而对蓄电池50进行充电的充电器。
在实施例的混合动力汽车20中,将发动机22、电动机MG1、驱动轴36与行星齿轮30连接并在驱动轴36上连接电动机MG2。也可以如图4的变形例的混合动力汽车220例示那样,在与驱动轮38a、38b连接的驱动轴36上经由变速器230连接电动机MG,并在电动机MG的旋转轴上经由离合器229连接发动机22,将来自发动机22的动力经由电动机MG的旋转轴和变速器230向驱动轴36输出,并将来自电动机MG的动力经由变速器230向驱动轴输出。而且,可以设为所谓串联混合动力汽车的结构。即,只要是具备与发动机、电动机、蓄电池、外部电源连接而对蓄电池进行充电的充电器的混合动力汽车即可,可以设为任意的结构。
对实施例的主要要素与用于解决课题的方案部分记载的发明的主要要素的对应关系进行说明。在实施例中,发动机22相当于“发动机”,燃料罐25相当于“燃料罐”,电动机MG2相当于“电动机”,蓄电池50相当于“蓄电池”,充电器60相当于“充电器”,通信装置94相当于“通信装置”。
另外,实施例的主要要素与用于解决课题的方案部分记载的发明的主要要素的对应关系是用于具体地说明实施例实施用于解决课题的方案部分记载的发明的方式的一例,因此没有对用于解决课题的方案一栏记载的发明的要素进行限定。即,关于用于解决课题的方案部分记载的发明的解释应基于该部分的记载进行,实施例只不过是用于解决课题的方案部分记载的发明的具体的一例。
以上,关于具体实施方式,使用实施例进行了说明,但是本发明不受这样的实施例的任何限定,在不脱离本发明的主旨的范围内,能够以各种方式实施,这是不言而喻的。
本发明能够利用于混合动力汽车的制造产业等。
