Description

车辆控制装置
技术领域
本发明涉及车辆控制装置,特别是涉及具有使发动机自动地启动的功能的车辆控制装置。
背景技术
在使用发动机的车辆中,长期间不运转发动机而放置的状况对汽油、发动机而言不优选。作为其理由,例如能够列举由于蒸发、氧化从而汽油的成分发生变化、发动机的润滑欠缺等。
在增程式(以下RE)、插入式混合动力(以下PHV)车辆中,若满充电后行驶距离不超过电池续航距离则发动机不启动,所以若反复进行每一次充电的行驶距离比电池续航距离短的行驶,则存在产生即使车辆频繁地行驶发动机也长期间不运转的状况的情况。这样的状况产生的概率与通常的汽油发动机车辆相比较高。
为了避免这样的状况,已知有在发动机在一定期间内未启动的情况下使发动机自动地启动的技术。这样的技术的例子记载于专利文献1。
专利文献1:美国专利申请公开第2011/0066352号说明书
然而,在以往的技术中,由于不管车辆是否行驶发动机均自动地启动,所以存在不符合驾驶员的利益这样的问题。例如,对于对RE车辆、PHV车辆期待汽油的消耗减少的驾驶员来说,在停车中强制地启动发动机而消耗汽油的情况违背期待。这违背驾驶员的利益。此外,这里所说的“利益”包括取决于驾驶员的主观的利益,并不一定与那样的控制客观地说是否对汽油的消耗减少作出贡献一致。
发明内容
本发明是为了解决这样的问题而完成的,目的在于在发动机在一定期间内未启动的情况下以符合驾驶员的利益的方式使发动机启动。
为了解决上述的问题,该发明所涉及的车辆控制装置是搭载于车辆的车辆控制装置,车辆具备内燃机、蓄电池、电动发电机或者电动机及发电机,车辆控制装置存储表示内燃机最后启动的日期的内燃机启动日,车辆控制装置具备第一控制功能,第一控制功能是在以内燃机启动日为起点经过了第一期间之后,在车辆行驶时使内燃机启动的功能。
根据这样的构成,在经过了第一期间之后,在车辆行驶时发动机自动地启动。
根据本发明的车辆控制装置,由于在经过了第一期间之后,在车辆行驶时发动机启动,所以能够以符合驾驶员的利益的方式使发动机启动,另外,也能够防止发动机长期间不启动的状况。
附图说明
图1是表示包含本发明的实施方式1所涉及的车辆控制装置的构成的图。
图2是表示图1的车辆控制装置的处理的流程的流程图。
图3是表示包含实施方式1的变形例所涉及的车辆控制装置的构成的图。
具体实施方式
以下,基于添附的附图对该发明的实施方式进行说明。
实施方式1.
图1表示包含本发明的实施方式1所涉及的车辆控制装置10的构成。车辆控制装置10搭载于车辆并控制车辆的动作。车辆具备车辆控制装置10、发动机40(内燃机)、电动发电机50以及蓄电池60。车辆控制装置10与发动机40以及电动发电机50连接,并控制这些设备。另外,电动发电机50具备从蓄电池60被供给电力来驱动发动机40的功能、和利用发动机40的动力发电并将其充电至蓄电池60的功能。也可以在电动发电机50与蓄电池60之间设置逆变器。
车辆控制装置10具有作为公知的计算机的构成,具备运算单元20以及存储单元30。运算单元20例如是微处理器,作为接受日程的输入的输入单元21、进行与日期等有关的判定的判定单元22以及进行与发动机40的自动启动有关的警告的警告单元23发挥作用。
存储单元30例如是半导体存储介质,存储行驶日程31、发动机启动日32(内燃机启动日)以及电池续航距离33。行驶日程31包括车辆行驶的预定的日期(行驶预定日)和表示每个行驶预定日的行驶预定距离的信息。表示行驶预定距离的信息例如是表示行驶的出发地以及目的地的坐标数据,例如能够以适合公知的GPS系统的形式来定义。基于表示行驶的出发地以及目的地的坐标数据计算行驶距离的方法,若为本领域技术人员,能够适当地设计。
发动机启动日32是表示发动机40最后启动的日期的值。
电池续航距离33能够由本领域技术人员适当地定义或者指定。例如,是表示从蓄电池60被充电到一定状态的状态(例如满充电的状态)到充电量成为零或者不能行驶的量为止,车辆仅靠电力能够行驶的距离的值。
输入单元21具有从驾驶员等使用者接受行驶日程31的输入的功能。该输入能够经由公知的接口进行,也可以经由汽车导航系统等所使用的触摸面板进行,也可以经由智能手机以无线进行,也可以从外部的计算机(自家设置的PC等)经由附属于充电电缆的信号线来进行。
图2是表示车辆控制装置10的处理的流程的流程图。图2的处理例如每当车辆的点火开关接通时开始执行。
首先车辆控制装置10获取行驶日程31(步骤S1)。另外,车辆控制装置10获取发动机启动日以及电池续航距离(步骤S2)。
接下来,车辆控制装置10作为判定单元22发挥作用,参照行驶日程31,判定在行驶预定日中,是否存在行驶预定距离比电池续航距离大的日子(步骤S3)。由于认为这样的日子需要发动机40的启动,所以能够认为是发动机启动预定日。
在存在发动机启动预定日的情况下,判定单元22判定该发动机启动预定日是否以发动机启动日为起点存在于规定的期间内(第二期间内)(步骤S4)。在存在多个发动机启动预定日的情况下,判定是否其中至少一个在规定的期间内。在本实施方式中第二期间为六周。该期间表示在保持发动机未启动的状态而经过的情况下对汽油、发动机带来负面影响的期间,能够由本领域技术人员适当地决定。
在发动机启动预定日存在于六周以内的情况下,判定单元22直至经过发动机启动预定日为止进行待机(步骤S5)。在存在多个相符合的发动机启动预定日的情况下,直至经过该所有相符合的发动机启动预定日为止进行待机。
其后,判定单元22判定发动机40在发动机启动预定日是否启动(步骤S6)。在启动了的情况下,判定单元22更新存储于存储单元30的发动机启动日(步骤S7)。即,将该发动机启动预定日的值作为新的发动机启动日进行存储。
在步骤S3中判定为不存在发动机启动日的情况下、在步骤S4中判定为行驶预定日不存在于六周以内的情况下、以及在步骤S6中判定为发动机40在发动机启动预定日没有启动的情况下,判定单元22判定在规定的期间内(以发动机启动日为起点,经过了第一期间后并且在经过第二期间之前)是否存在行驶预定日(步骤S8)。在本实施方式中第一期间为五周,第一期间能够由本领域技术人员适当地决定。其中,第一期间的长度在第二期间的长度以下。
在该期间内存在行驶预定日的情况下,判定单元22在该期间内以发动机启动日为起点经过了五周之后,在车辆行驶时使发动机40启动(步骤S9)。将该步骤S9的功能设为第一控制功能。作为一个例子,第一控制功能是在以发动机启动日为起点经过了五周的时刻车辆未行驶的情况下,在其后车辆最初开始行驶的时刻使发动机40启动,在以发动机启动日为起点经过了五周的时刻车辆正行驶的情况下,在该时刻使发动机40启动的功能,但并不限定于严格地实现这样的动作的功能。例如,也可以在以发动机启动日为起点经过了五周的时刻车辆正行驶的情况下,从该时刻起规定时间后(例如几分钟后)使发动机40启动。此外,基于该控制的发动机40的启动,只要车辆不行驶就不被执行,所以即使是不依赖于驾驶员意思的强制的自动启动,也不会违背驾驶员的利益。
此外,也可以在步骤S9后设置与步骤S6相同的分支。例如,也可以在以发动机启动日为起点经过六周而车辆不行驶,作为结果未执行第一控制功能的情况下,处理移至步骤S10。
在执行了步骤S9之后,判定单元22更新存储于存储单元30的发动机启动日(上述的步骤S7)。
如根据上述所明确的那样,步骤S9的控制在步骤S3以及S4中向下侧分支的情况下(即,在判定为在以发动机启动日为起点六周以内存在发动机启动预定日的情况下)不执行。即,在存在那样的发动机启动预定日的情况下,即使在以发动机启动日为起点经过了五周之后,到经过该发动机启动预定日为止也不执行步骤S9的控制。作为结果,即使在保持发动机40不启动的状态经过五周,其后车辆行驶了的情况下,只要没有其他的事由,发动机40就不启动。
在步骤S8中,在经过五周后经过六周前不存在行驶预定日的情况下,警告单元23在六周以内发动机40未启动的情况下进行警告(步骤S10)。该警告例如在点火开关接通时进行。警告的内容例如包括表示从发动机启动日开始经过了六周的信息、和表示在从进行了警告的时刻起24小时以内发动机40未启动的情况下进行使发动机40自动地启动的控制的信息。另外,该警告例如经由公知的接口(触摸面板以及扬声器等)进行。
接下来,判定单元22判定警告后24小时以内发动机40是否启动(步骤S11)。这里,也可以在警告后24小时以内车辆行驶的情况下,将处理移至步骤S9,自动地使发动机40启动。
在警告后24小时以内发动机40启动的情况下,判定单元22更新存储于存储单元30的发动机启动日(上述的步骤S7)。另一方面,在即使警告后经过24小时发动机40也未启动的情况下,判定单元22在24小时经过后自动地使发动机40启动(步骤S12)。该步骤S12的处理也可以在点火开关断开的情况下延期执行,在该情况下也可以在点火开关接通的时刻执行。
以下对沿着以上那样的流程图的车辆控制装置10的实际的动作的例子进行说明。
设作为发动机启动日32,存储了3月24日(例如2013年,以下相同)这样的日期。另外,设作为电池续航距离33,存储了200km这样的值。
另外,设作为行驶日程31,存储了以下的内容。
-3月25日~4月28日工作日自家与工作地之间的往复(行驶距离20km),休息日不行驶
-5月1日从自家向观光地移动(行驶距离300km)
-5月2日~5月3日不行驶
-5月4日从观光地向自家移动(行驶距离300km)
-5月5日~8月11日工作日自家与工作地之间的往复(行驶距离20km),休息日不行驶
在该例中,发动机启动预定日即行驶距离比电池续航距离(200km)大的日子是5月1日和5月4日,均符合以发动机启动日(3月24日)为起点经过五周后经过六周前。因此处理移至步骤S5,到经过5月4日为止,即使车辆行驶也不执行发动机40的自动启动。在违背预定而在5月1日和4日发动机40均未启动的情况下,根据步骤S9,在经过了5月4日的时刻即5月5日,在车辆行驶的时刻发动机40启动。并且,在经过六周为止(即经过5月5日为止)车辆不行驶从而发动机40未启动的情况下,处理移至步骤S10,在警告后,发动机40自动地启动。
这样,根据实施方式1所涉及的车辆控制装置10,通过存储行驶日程31并进行参照,能够基于行驶日程31来决定何时使发动机启动才高效,并与该结果对应地自动地启动发动机40。在上述的例子中,到经过发动机启动预定日(5月4日)为止,即使车辆行驶也不执行发动机40的自动启动,所以能够抑制汽油的消耗来提高燃料经济性。另外,在经过了发动机启动预定日之后,在经过六周之前,在车辆行驶的时刻发动机40启动,所以能够以符合驾驶员的利益的方式使发动机40启动。并且,在经过了六周的情况下,与车辆的行驶无关地启动发动机40,所以能够更可靠地避免对发动机40等的负面影响。
在上述的实施方式1中,能够实施以下那样的变形。
车辆控制装置10也可以还与蓄电池60连接,并控制蓄电池60。另外,车辆控制装置10也可以具备获取表示蓄电池60的状况的信息,例如如图3所示与劣化程度有关的信息的功能。蓄电池60存在因充放电的反复进行而劣化的情况,在那样的情况下存在电池续航距离变动的可能性,但即使在那样的情况下,通过车辆控制装置10获取与劣化程度有关的信息并使用于控制,也能够进行更适应于蓄电池60的状况的车辆控制。例如,车辆控制装置10也可以具备基于获取的劣化程度决定电池续航距离33的功能、和将决定的电池续航距离33存储于存储单元30的功能(或者更新存储于存储单元30的电池续航距离33的功能)。
另外,电动发电机50也可以是独立地设置的电动机和发电机的设备。
第一期间(五周)以及第二期间(六周)能够适当地变更。特别是,也可以对于第一期间能够由驾驶员变更。该情况下,也可以输入单元21接受表示第一期间的值的输入并存储于存储单元30。这样一来,根据驾驶员的喜好,能够通过缩短第一期间来更频繁地使发动机40自动启动,使警告的频率减少,也能够通过延长第一期间来提高燃料经济性。
在实施方式1中,发动机启动预定日以日期单位来决定,但也可以以充电机会为单位进行。例如,在考虑经过多日没有充电机会的情况下(不能够回到自家的情况下等),也可以以从充电机会到下一个充电机会为止为单位来决定发动机启动预定期间,并将其代替发动机启动预定日来使用。在这样的构成中,在实施方式1的动作例中,从5月1日到5月5日作为单一的发动机启动预定期间来处理。
