Abstract

本发明的启动控制在电动机温度Tm1或Tm2从预定初始启动温度Tset每升高10℃的定时,重复执行用于启动在电动机冷却系统压力供给油流的油泵的启动处理(步骤S100到S180)。该方案即使在由于较低的外界空气温度Tout而导致油流具有高粘度时,可提高成功启动油泵的可能性。在经重复执行启动处理的油泵启动失败的情况下,在外界空气温度Tout不低于预定参考温度Tref时,该启动控制判定在油泵中或在对油泵的供电中发生异常,而在外界空气温度Tout低于预定参考温度Tref时,不判定在油泵中或在对油泵的供电中发生异常(S190至S220)。这种方案有效地排除了在油泵中或在对油泵的供电中的异常的错误检测。

Description

冷却装置、冷却装置的控制方法和异常判定方法
技术领域
本发明涉及一种电动机的冷却装置,该冷却装置的控制方法,和在冷却装置启动时的异常判定方法。更具体而言,本发明涉及一种提供冷却油流以冷却安装在车辆上且被驱动以输出驱动力的电动机的冷却装置,以及该冷却装置的控制方法,和判定在所述冷却装置启动时发生的异常情况的异常判定方法。
背景技术
提议的一种冷却装置在油流的温度达到或超过预定温度水平时,驱动电动油泵将作为变速器的驱动源的油流供给散热器,并冷却该油流(参见,例如,日本专利特开2000-227150号公报)。在该现有技术结构中,电动机布置得距离与变速器处于同一壳体内的变矩器非常近。冷却所述油流从而防止电动机温度升高。
发明内容
在现有技术的借助通过经散热器与外界空气进行的热交换而冷却的油流来冷却电动机的冷却装置中,在外界空气温度非常低的情况下,散热器中的油处于低温和高粘度。油流的高粘度可能防碍电动油泵的成功启动。电动油泵的启动故障自然导致电动机的冷却故障。冷却装置可被设计为在启动故障时发出电动油泵的异常通知。即使在电动油泵的启动故障是由于低温外界空气导致的情况下,现有技术的冷却装置也会发出正常电动油泵的异常情况的错误通知。
因此,本发明的冷却装置和冷却装置控制方法的目的是提高压力供给单元,例如压力供给冷却油流的电动油泵,的成功启动的可能性。本发明的冷却装置、冷却装置控制方法和异常判定方法的目的是正确判定发生在压力供给单元,例如压力供给冷却油流的电动油泵,中的异常情况。
为了实现至少部分上述和其它有关目的,本发明的冷却装置,冷却装置的控制方法和异常判定方法具有下文所述的构造。
本发明的第一冷却装置是一种供给冷却油流以冷却安装在车辆上并被驱动以输出驱动力的电动机的冷却装置。该第一冷却装置包括:通过与外界空气进行热交换来冷却冷却油流的热交换单元;设置在形成于所述电动机和所述热交换单元之间的冷却油循环路径中、以压力供给所述冷却油流并经冷却油循环路径循环所述冷却油流的压力供给单元;测量电动机的温度的电动机温度测量单元;和启动控制模块,该启动控制模块在测得的所述电动机的温度升高到预定启动温度时,执行用于启动所述压力供给单元的启动控制,并且在所述压力供给单元启动失败的情况下,在每当测得的所述电动机的温度升高到高于所述预定启动温度的多个不同温度之一时,重复执行所述启动控制达到预定次数,直到所述压力供给单元成功启动为止。
当测得的被驱动以输出驱动力的电动机的温度升高到预定启动温度时,本发明的第一冷却装置执行用于启动压力供给单元的启动控制,该压力供给单元设置在形成于所述电动机和通过与外界空气进行热交换来冷却冷却油流的热交换单元之间的冷却油循环路径中、以压力供给所述冷却油流并经冷却油循环路径循环所述冷却油流。在压力供给单元的启动失败的情况下,所述第一冷却装置在测得的电动机温度每升高到高于预定启动温度的多个不同温度之一时,重复执行启动控制达到预定次数,直到压力供给单元成功启动为止。在压力供给单元的启动失败的情况下,重复执行启动控制达到预定次数。与尝试执行压力供给单元的启动仅一次的传统冷却装置相比较,这种方案提高了压力供给单元成功启动的可能性,从而有效地冷却了电动机。
在本发明的第一冷却装置中,所述高于预定启动温度的多个不同的温度可具有预定温度间隔的温度差。在测得的电动机温度每升高预定温度间隔的定时,冷却装置执行用于启动压力供给单元的启动控制。这就提高了压力供给单元成功启动的可能性。
在本发明的第一冷却装置的一个优选应用中,在通过重复所述启动控制所述预定次数而所述压力供给单元启动失败的情况下,所述启动控制模块发出异常的通知。与尝试执行压力供给单元的启动仅一次且在压力供给单元启动失败时发出异常通知的传统冷却装置相比较,这种方案发出适当的异常通知。在本申请的一个优选实施例中,第一冷却装置还包括测量外界空气温度的外界空气温度测量单元。当测得的外界空气温度低于预定低参考温度时,在通过重复所述启动控制所述预定次数而所述压力供给单元启动失败的情况下,所述启动控制模块不发出异常的通知。当压力供给单元的启动失败是由于在低外界空气温度的情况下冷却油的高粘度而导致时,本实施例的第一冷却装置不发出压力供给单元异常的通知。因此,这种方案有效地避免了正常压力供给单元异常的错误通知。
本发明的第二冷却装置是一种供给冷却油流以冷却安装在车辆上并被驱动以输出驱动力的电动机的冷却装置。该第二冷却装置包括:通过与外界空气进行热交换来冷却所述冷却油流的热交换单元;设置在形成于所述电动机和所述热交换单元之间的冷却油循环路径中、以压力供给所述冷却油流并经所述冷却油循环路径循环所述冷却油流的压力供给单元;测量电动机的温度的电动机温度测量单元;测量外界空气温度的外界空气温度测量单元;启动控制模块,该模块在测得的所述电动机的温度升高到预定启动温度时,执行用于启动所述压力供给单元的启动控制;和异常判定模块,该异常判定模块在通过所述启动控制模块的启动控制而所述压力供给单元启动失败的情况下,在测得的外界空气温度不低于预定低参考温度时,判定异常发生,而在测得的外界空气温度低于预定低参考温度时,不判定异常发生。
当测得的被驱动以输出驱动力的电动机的温度升高到预定启动温度时,本发明的第二冷却装置执行用于启动压力供给单元的启动控制,该压力供给单元设置在形成于所述电动机和通过与外界空气进行热交换来冷却冷却油流的热交换单元之间的冷却油循环路径中、以压力供给所述冷却油流并经冷却油循环路径循环所述冷却油流。在经启动控制的压力供给单元的启动失败的情况下,所述第二冷却装置在测得的外界空气温度不低于预定低参考温度时判定异常发生,而在测得的外界空气温度低于预定低参考温度时不判定异常发生。本发明的第二冷却装置有效地检测导致压力供给单元启动失败的压力供给单元的异常,但不将由于在低外界空气温度时冷却油的高粘度而导致的压力供给单元的启动失败归因于压力供给单元的异常。因此,这种方案有效地避免了正常压力供给单元异常的错误检测。
本发明的冷却装置控制方法是一种控制冷却装置的冷却装置控制方法,所述冷却装置包括:通过与外界空气进行热交换来冷却冷却油流的热交换单元;设置在形成于被驱动以输出车辆驱动力的电动机和所述热交换单元之间的冷却油循环路径中、以压力供给所述冷却油流并经所述冷却油循环路径循环所述冷却油流的压力供给单元。在测得的所述电动机的温度升高到预定启动温度时,所述冷却装置控制方法执行用于启动所述压力供给单元的启动控制,在所述压力供给单元的启动失败的情况下,在每当测得的所述电动机的温度升高到高于所述预定启动温度的多个不同温度之一时,重复执行所述启动控制达到预定次数,直到所述压力供给单元的启动成功为止。

在本发明的冷却装置控制方法中,所述高于预定启动温度的多个不同的温度具有预定温度间隔的温度差。在测得的电动机温度每升高预定温度间隔的定时,冷却装置执行用于启动压力供给单元的启动控制。这就提高了压力供给单元成功启动的可能性。
在一个优选应用中,在通过重复所述启动控制所述预定次数而所述压力供给单元启动失败的情况下,所述冷却装置控制方法判定异常发生。与尝试执行压力供给单元的启动仅一次且在压力供给单元启动失败时发出异常通知的传统冷却装置控制方法相比较,这种方案发出适当的异常通知。在本申请的一个优选实施例中,当测得的外界空气温度低于预定低参考温度时,即使在通过重复所述启动控制所述预定次数而所述压力供给单元启动失败的情况下,所述冷却装置控制方法也不判定异常发生。当压力供给单元的启动失败是由于在低外界空气温度的情况下冷却油的高粘度而导致时,本实施例的冷却装置控制方法不发出压力供给单元异常的通知。因此,这种方案有效地避免了正常压力供给单元异常的错误通知。

本发明的异常判定方法在冷却装置启动时判定异常。该异常判定方法在测得的电动机的温度升高到预定启动温度时执行用于压力供给单元的启动的启动控制。在经启动控制的压力供给单元启动失败的情况下,在测得的外界空气温度不低于预定低参考温度时,所述异常判定方法判定异常发生,而在测得的外界空气温度低于预定低参考温度时,不判定异常发生。本发明的异常判定方法有效地检测导致压力供给单元启动失败的压力供给单元的异常,但不将由于在低外界空气温度时冷却油的高粘度而导致的压力供给单元的启动失败归因于压力供给单元的异常。因此,这种方案有效地避免了正常压力供给单元异常的错误检测。

具体实施方式
实施本发明的一种方式作为优选实施例在下文中进行说明。图1示意性显示了装有本发明一个实施例中的电动机冷却装置的混合动力车10的构造。本实施例的混合动力车10具有在发动机电子控制单元14(发动机ECU14)的运行控制下驱动的发动机12,包括与发动机12的曲轴相连的行星架和与前轮车轴连接的驱动轴相连的齿圈的行星齿轮机构16,具有与行星齿轮机构16的太阳齿轮相连的旋转轴且具有发电能力的电动机MG1,和具有与驱动轴相连的旋转轴且具有发电能力的电动机MG2。本实施例的混合动力车10还具有:包括散热器34和被驱动从而经过散热器34和发动机12之间的冷却水循环路径32来循环冷却水流的冷却水泵36的发动机冷却循环系统30,冷却作为用于润滑和冷却电动机MG1和MG2的润滑/冷却介质的油流的电动机冷却循环系统40,和控制整个混合动力车10的运行的混合动力电子控制单元50。伴随着电池24的充电和放电,电动机MG1和MG2在电动机电子控制单元20(电动机ECU20)的控制下被驱动。电动机ECU20执行包含在分别作为电动机MG1和MG2的驱动电路的逆变器21和22中的开关元件的开关控制。
电动机冷却循环系统40包括:位于混合动力车10的前部且通过与外界空气进行热交换来冷却油流的油冷却器44,与油冷却器44并联连接电动机MG1和MG2且在油冷却器44与电动机MG1和MG2之间循环油流的油循环路径42,从电动机MG1和MG2将油流压力供给油冷却器44并经过油循环路径42循环油流的油泵46。
混合动力电子控制单元50被构造成包括CPU52、存储处理程序的ROM54、临时存储数据的RAM56、输入和输出端口(未示出)、以及通信端口(未示出)的微型计算机。该混合动力电子控制单元50经由其输入端口,从分别与电动机MG1和MG2相连的温度传感器60和62接收电动机温度Tm1和Tm2,从位于混合动力车10的前部外侧的外界空气温度传感器64接收外界空气温度Tout,从换档位置传感器72接收换档位置SP或换档杆71的当前放置位置,从加速器踏板位置传感器74接收加速器开度Acc或驾驶员对加速器踏板73的压下量,从制动踏板位置传感器76接收制动踏板位置BP或驾驶员对制动踏板75的压下量,从车速传感器78接收车速V。混合动力电子控制单元50经由其输出端口将驱动信号输出给油泵46。混合动力电子控制单元50经由其通信端口与发动机ECU14和电动机ECU20建立通信,从而向发动机ECU14和电动机ECU20发送和从发动机ECU14和电动机ECU20接收各种控制信号和数据。
这样构造的本实施例的混合动力车10,根据车速V和对应于驾驶员对加速器踏板73的压下量的加速器开度Acc设定将输出给驱动轴的扭矩需求,并控制发动机14和电动机MG1、MG2的运行,以确保将相当于所述扭矩需求的所需动力输出给驱动轴。混合动力车10的运行控制并不是本发明的特征,因此在本说明书中对其不进行特别说明。
在本实施例的结构中,电动机的冷却装置包括:具有油循环路径42、油冷却器44和油泵46的电动机冷却循环系统40,与电动机MG1和MG2相连的温度传感器60和62,外界空气温度传感器64和混合动力电子控制单元50。
本说明书与上述构造的本实施例的冷却装置的操作有关。图2为流程图,显示了在油泵46启动时,由混合动力电子控制单元50执行的启动控制程序(例程)。在本实施例的冷却装置中,当由温度传感器60和62测量的电动机MG1和MG2的电动机温度Tm1和Tm2之一达到初始启动温度Tset,例如,100C°或120C°时,混合动力电子控制单元50执行该启动控制程序。
在图2的启动控制程序中,混合动力电子控制单元50的CPU52首先将计数器N复位为0(步骤S100),执行用于启动油泵46的启动处理(步骤S120),等待经过预定时间间隔(步骤S120),并确认油泵46的启动是成功还是失败(步骤S130)。由于响应油泵46的启动指令以完成油泵46的启动需要花费时间,因此在经过所述预定时间间隔之后,判定油泵46的启动成功还是失败。经电动机冷却循环系统40中的油循环路径42循环的油流在低温时具有较高的粘度,从而增加了经油冷却器44进行循环的阻力。增加的油流阻力可能导致油泵46启动失败。在油泵46故障或异常的情况下,或者在供给油泵46电力失败的情况下,油泵46自然不能启动。本实施例的启动控制程序在步骤S130判定由于这些原因中的任何一个而导致的油泵46启动故障。除非外界空气温度非常低或者除非油泵46中或油泵46的电力供给中发生任何异常,油泵46都会立即启动。在步骤S130中当判定油泵46的启动成功时,CPU52立即从图2的启动控制程序中退出。
相反,在步骤S130中当由于任何原因而导致油泵46的启动故障时,CPU52判定计数器N是否仍低于预定参考值Nref(步骤S140)。当计数器N仍然低于该预定参考值Nref时,CPU52使计数器N加1(步骤S150),并将十倍计数器N增加到初始启动温度Tset,以设定启动温度Tst(步骤S160)。CPU52等待,直到从温度传感器60和62输入的电动机温度Tm1和Tm2之一达到该启动温度Tst(步骤S170和S180)为止,并返回步骤S110以便再次执行用于使油泵46启动的启动处理。在步骤S130中当判定油泵46的启动失败时,在电动机温度Tml和Tm2之一从初始启动温度Tset每升高10C°的定时,启动控制程序重复执行用于启动油泵46的启动处理,直到判定油泵46的启动成功时为止。例如,在电动机温度Tml和Tm2之一从120C°的初始启动温度Tset升高到130C°、140C°和150C°的定时,启动控制程序重复执行用于启动油泵46的启动处理,直到判定油泵46的启动成功时为止。按照这种方式,在电动机温度Tml和Tm2之一每升高10C°的定时,尝试启动油泵46。在外界空气温度较低时具有较高粘度的油流借助电动机MG1和MG2的热量被逐渐加热。因此,油流的粘度降低并使油泵46成功启动。参考值Nref判定用于启动油泵46的启动处理的重复次数。例如,参考值Nref设定为3,用于重复启动处理4次,参考值Nref设定为4,用于重复启动处理5次。在电动机温度Tml和Tm2之一从初始启动温度Tset每升高10C°的定时,重复执行用于启动油泵46的启动处理期间,可在步骤S130判定油泵46的启动成功。这种判定表示油泵46的启动目的的实现,并结束启动控制程序。
在电动机温度Tm1和Tm2之一从初始启动温度Tset每升高10C°的定时重复执行用于启动油泵46的启动处理期间,当计数器N不低于预定参考值Nref而在步骤S140中达到预定参考值Nref时,CPU52从外界空气温度传感器64输入外界空气温度Tout(步骤S190)。在步骤S200中,当输入外界空气温度Tout不低于预定参考温度Tref时,CPU52判定在油泵46中或在对油泵46的供电中发生异常,并发出发生异常的通知(步骤S210)。该通知可点亮位于驾驶员座位前的仪表盘上的故障灯。然后,CPU52从图2的该启动控制程序中退出。所述参考温度Tref表示油流增大的粘度导致油泵46启动困难的温度值,并且取决于油泵46的性能,用于电动机冷却循环系统40的油的特性和油冷却器44的结构。相反,在步骤S200中,当外界空气温度Tout低于预定参考温度Tref时,CPU52将油泵46启动的故障归因于由于低外界空气温度Tout而导致的油流的高粘度。CPU52将启动故障标记F设定为值1(步骤S220),而不通知异常,并从图2的启动控制程序中退出。设定启动故障标记F有效地鉴别了是由于低外界空气温度Tout而导致的油泵46启动失败,还是由于油泵46中或对油泵46的供电中的异常导致的油泵46启动失败。
在电动机的冷却装置中,本实施例的启动控制在电动机温度Tm1和Tm2之一从初始启动温度Tset每升高10C°的定时重复执行用于启动油泵46的启动处理。该启动控制提高了油泵46成功启动的可能性,即使是在相对较低的外界空气温度时油流具有高粘度的情况下也是如此。在重复执行启动程序的油泵46启动失败的情况下,在相对较低的外界空气温度Tout的状况下,所述启动控制不判定在油泵46中或在对油泵46的供电中发生异常。这种方案有效地排除了在油泵46中或在对油泵46的供电中的异常的错误检测。
在电动机的冷却装置中,本实施例的启动控制在电动机温度Tm1和Tm2之一从初始启动温度Tset每升高10C°的定时重复执行用于启动油泵46的启动处理。启动处理每次重复的温度升高度数并不限于10C°,而可以设定为任意值。例如,可以在电动机温度Tm1和Tm2之一从初始启动温度Tset每升高5C°的定时重复执行用于启动油泵46的启动处理。另一种可能的变化可以为执行用于启动油泵46的启动处理设定多个温度。所述多个温度可不具有固定的温度间隔。该多个温度的温度间隔可在较高温度时变窄,例如,120C°,130C°,137C°和142C°。所述多个温度可以随机设定,而没有任何特定规律。
在电动机的冷却装置中,即使在借助重复执行启动处理的油泵46的启动失败的情况下,本实施例的启动控制在相对较低的外界空气温度Tout的情况下不判定在油泵46或者在对油泵46的供电中发生异常。启动控制的一种可能的变化在借助重复启动处理的油泵46的启动失败的情况下,可以独立于外界空气温度Tout来判定在油泵46中或在对油泵46的供电中发生异常。
在电动机的冷却装置中,在电动机温度Tm1和Tm2之一从初始启动温度Tset每升高10C°的定时借助重复执行启动处理的油泵46的启动失败的情况下,本实施例的启动控制在外界空气温度Tout不低于预定参考温度Tref时判定在油泵46中或者在对油泵46的供电中发生异常。该启动控制在外界空气温度Tout低于预定参考温度Tref时,不判定在油泵46中或者在对油泵46的供电中发生异常。所述启动控制的一种可能的变化可在电动机温度Tm1和Tm2之一达到初始启动温度Tset时仅执行用于启动油泵46的启动处理一次。在油泵46的启动失败的情况下,所述变化的启动控制在外界空气温度Tout不低于预定参考温度Tref时判定在油泵46中或者在对油泵46的供电中发生异常。在外界空气温度Tout低于预定参考温度Tref时,所述变化的启动控制不判定在油泵46中或者在对油泵46的供电中发生异常。
本实施例涉及用于冷却装备有发动机12、行星齿轮机构16、和电动机MG1和MG2的混合动力车辆10中的电动机MG1和MG2的冷却装置。本发明的冷却装置可具有任何设计,来冷却安装在任何结构的车辆上且被驱动以输出驱动力的电动机和发电机。例如,一种变化的例子的冷却装置安装在如图3所示的机动车10B上,并被致动以冷却驱动电动机MG。该变化的例子的冷却装置具有电动机冷却循环系统40B。所述电动机冷却循环系统40B包括位于机动车10B前部的油冷却器44B,在油冷却器44B和电动机MG之间循环油流的油循环路径42B,和将油流从电动机MG压力供给到油冷却器44B的油泵46B。
本实施例涉及用于冷却安装在混合动力车10上的电动机MG1和MG2的冷却装置。本发明的技术还可作为用于冷却安装在混合动力车10上的电动机MG1和MG2的冷却装置的控制方法,或者作为在冷却装置启动时的异常判定方法来实施。
无论从哪个方面来看,上文所述实施例及其变化都是举例说明性的而非限制性的。在不背离本发明的主要特征的范围或精神的情况下,还可以进行多种其它改变、变化和变更。
本发明的技术优选应用于电动机冷却装置的制造业以及其它相关行业。
