本发明提供一种用于当TMED混合动力车被驱动时防止电动机过热的控制方法及系统，其可通过在基于车辆以EV模式驱动时的驱动状态以及电动机的当前温度来限制电动机输出之前运行发动机以改善行驶性能。所述方法包括：监测混合动力车的电动机温度，并且当所述车辆以EV模式驱动，且所述电动机的当前电动机温度为第一电动机温度或者更高时，运行发动机。此外，在发动机运行后，当所述当前电动机温度等于或者大于第三电动机温度时，电动机输出受限，其中所述第三电动机温度大于所述第一电动机温度。

Description

用于防止当TMED混合动力车被驱动时电动机过热的控制方法 及系统
技术领域
本发明涉及用于防止当安装有离合器的电动设备的(TMED：transmissionmounted electric device)混合动力车被驱动时电动机过热的控制系统及方法。更特别地，其涉及用于防止当TMED混合动力车以电动车(EV:electric vehicle)模式驱动时，由于发动机过热导致的发动机性能劣化的控制方法及系统。
背景技术
混合动力车是利用发动机及电动机作为动力源的环境友好车辆。总体来说，混合动力车通过电动机利用电池电能进行驱动，直到其在起动后达到预设速度，以及其可基于驾驶意图与电池状态，适当地联合电动机动力及发动机动力进行驱动。
安装有离合器的电动设备的(TMED)混合动力车是采用了TMED的混合动力车，并且电动机安装在TMED混合动力车中以连接到变速器。即，电动机置于发动机离合器与变速器之间。TMED混合电动车也能通过电动机使用电池电能进行驱动，直到其在起动后达到预设速度，并且TMED混合动力车的驱动模式可被分为混合电动车(HEV:hybrid electriccehicle)模式及EV模式，在混合电动车(HEV)模式中，发动机及电动机都被驱动，在EV模式中，电动机被驱动。
同时，当电池中还留有足够电量时，现有技术中的TMED混合电动车和插电式混合电动车(PHEV:plug-in hybrid electric vehicle)使用电池中积累的电能，以最优燃料效率控制在EV模式下进行驱动。此外，车辆可通过使用具有高容量的电动机，在不单独需要驱动力的驱动情况下，执行再生制动，因此，其通过混合操作能够获得相较于现有普通车辆更高的燃料效率。
然而，当车辆在足够高的速度下进行驱动或者以电动机高幅输出进行驱动时，由电动机排放的热量增多，并且当电动机的温度升高至预设值水平或者更高水平时，发动机不顾驾驶意图进行运行，或是由于电动机过热引起的限制输出而导致在维持行驶性能中限制将会存在。
即，当现有技术中的TMED混合动力车在EV模式下以足够高的速度或者以相当大的负载进行驱动时，且当电动机过热至预设水平或者更高水平时，执行限制电动机功率的操作，用以保护电动机系统，电动机输出受限，因此，发动机补偿不足的动力。
然而，当由于电动机输出劣化，发动机不顾驾驶意图突然被操作时，可能无法获得驾驶者所需的驱动力，直至源自发动机的驱动力被充分传送至车轮上，因此，在允许发动机以线性方式进行操作中存在限制。更进一步地，由于电动机输出的限制，车辆不能以最大输出进行驱动，即，直至电动机冷却至预设水平或者更低水平。
特别地，对于PHEV，与现有HEV相比，当车辆通过使用电动机及具有高容量的电池以高负载在EV模式下驱动时，由电动机排放的热量进一步地增多，因此，用于解决在车辆被驱动时电动机过热问题的替代品被认为与改善驱动系统相关。
在本部分如上所公开的信息仅用于增强对于本发明背景的理解，因此它可以包含对于该国本领域普通技术人员已知的不构成现有技术的信息。
发明内容
本发明提供用于防止当TMED混合动力车被驱动时电动机过热的控制方法，该方法能够考虑TMED混合动力车以EV模式驱动的驱动状态与当前电动机温度，在限制电动机输出之前，通过运行发动机来预防电动机过热，以及改善行驶性能。
本发明一方面提供了用于防止当TMED混合动力车被驱动时电动机过热的方法，该方法包括：监测混合动力车的电动机温度；当车辆以EV模式驱动时，且电动机的当前电动机温度为第一电动机温度或者高于第一电动机温度时，运行发动机；以及在运行发动机后，当该当前电动机温度等于或者大于第三电动机温度时，限制电动机的输出，其中该第三电动机温度高于该第一电动机温度；此外，限制电动机输出的步骤可包括使用已经达到第三电动机温度的当前电动机温度作为输出限制因素，确定最终电动机的输出，并且将电动机输出限制到该已确定的最终电动机的输出或限制在该已确定的最终电动机的输出以下。
更进一步地，在电动机的当前电动机温度等于或者高于第二电动机温度时，可以限制该电动机的输出，其中该第二电动机温度高于第一电动机温度且低于第三电动机温度，在执行再生制动时，使用已经达到第二电动机温度的当前电动机温度作为输出限制因素，可以确定最终电动机的输出，并且该电动机的输出可被限制到已确定的最终电动机输出或已确定的最终电动机输出以下。当车辆外界温度为预设温度或者高于预设温度时，或者当变速器油温为参考温度或者高于参考温度时，使用外界温度或者变速器油温作为温度校正因素来校正电动机温度值，并将校正后的电动机温度值用作当前电动机温度。
根据用于防止根据本发明的TMED混合动力车被驱动时电动机过热的控制方法，发动机可在电动机输出受限之前进行操作，其中电动机输出受限是由于车辆被驱动时电动机温度升高导致电动机过热所引起的，如此使得电动机输出可逐渐减少，因此能够防止电动机过热，保证线性制动性能，改善起动及加速性能。

在下文中，本文将进行描述以便于本发明所属技术领域内的技术人员能够容易地实施本发明。值得注意的是，下述方法可通过具有存储器与处理器的处理器执行。
在本发明中如图1，当TMED混合动力车以EV模式驱动，且电动机温度升高时，发动机可在电动机温度达到电动机输出需要限制的温度之前运行，并且电动机输出逐步减少，因此防止了电动机过热，保证了线性制动特性并且改善了起动及加速性能。由于电池放电引起的电动机输出(例如：驱动转矩)限制以及由于电池充电引起的电动机输出(例如：充电转矩)限制被区分开，再生制动的可能性减小，因此甚至在再生制动过程中可防止电动机过热。
根据图2及图3，当TMED混合动力车以EV模式驱动时电动机的当前温度可以被监测，其用于防止当TMED混合动力车驱动时电动机过热。
特别地，车辆的驱动条件将同时被监测，并且影响电动机温度的外界温度，以及变速器油温也将被监测。当外界温度高于预设温度或者当变速器油温高于参考温度时，基于驱动条件，电动机温度值可使用外界温度值及变速器油温值作为温度校正因素来进行校正，并且随后可基于校正的电动机温度值(例如：当前电动机温度)判断是否应当运行发动机。
变速器油温指的是安装在发动机后侧的变速器中油的温度。在TMED混合动力车中，变速器连接到通过发动机离合器与发动机相连的电动机的后侧。即，电动机被连接至发动机离合器与变速器之间。当车辆通过电动机运行被驱动时，即，当车辆以EV模式驱动时，其中车辆被驱动同时电池被放电，可以比较当前电动机温度与第一电动机温度T1。基于比较结果，当当前电动机温度等于或者大于第一电动机温度T1时，电动机控制器可以配置成请求发动机控制器运行发动机。
上述被电动机控制器请求运行发动机的发动机控制器，可被配置成产生发动机转矩命令，运行发动机，并且接合电动机与发动机之间的发动机离合器，并且也可被配置成将发动机转矩应用至与电动机连接的车轮上，以允许车辆在电动机输出减少时能被驱动。
当车辆以EV模式驱动时，同时发动机运行时，电动机输出可相对的减少至驾驶员所需的转矩(例如，发动机转矩+电动机转矩)。特别地，当当前电动机温度升高至等于或者大于第三电动机温度T3时，电动机的驱动转矩(例如：放电输出)可被限制于预设值及其以下。即，当当前电动机温度为第三电动机温度T3或者更高时，由于电池放电引起的电动机输出可被限制于预设值及其以下，且当当前电动机温度为第三电动机温度或者更低时，电动机温度将被再次监测。
特别地，电动机转矩可使用为第三电动机温度T3或者更高的当前电动机温度作为放电限制因素，基于驱动操作进行限制，并且基于该当前电动机温度限制的电动机转矩值可被确定为最终电动机转矩。
当车辆被驱动同时电池正在充电时，即，当车辆以再生制动模式驱动以给电池充电时，当前电动机温度可与第二电动机温度T2相比较。基于比较结果，当当前电动机温度为第二电动机温度T2或者更高时，电动机的充电转矩(例如：充电输出)可被限制至预设值，并且当当前电动机温度为第二电动机温度T2或者更低时，电动机温度可被再次监测。
当当前电动机温度为第二电动机温度T2或者更高时，电动机的充电转矩可使用为第二电动机温度或者更高的当前电动机温度作为充电限制因素(例如：输出限制因素)，依据再生制动进行限制，并且基于该当前电动机温度所限制的电动机转矩值可被确认为最终电动机转矩。
如上所述，根据本发明，在车辆使用电动机输出作为动力而被驱动时(例如：在驱动操作的过程中)，且当当前电动机温度值(例如：基于驱动条件校正的电动机温度值)达到第一电动机温度T1时，发动机将被运行，并且电动机输出将被减少(例如：EV线将缩短)。更进一步地，当当前电动机温度值达到第三电动机温度T3时，电动机的驱动转矩(例如：电动机输出)将开始受限。
当当前电动机温度达到第二电动机温度T2时，以及当电池通过再生制动使用电动机输出进行充电时(例如，当车辆被驱动的同时电池进行充电)，电动机的充电转矩(例如：电动机输出)将开始受限。特别的，当车辆以EV模式驱动，发动机运行，用以将发动机转矩应用于车轮上时，第一电动机温度T1可被达到，当电动机的充电转矩受限于预设值及其以下时，第二电动机温度T2可被达到，并且当电动机的放电转矩受限于预设值及其以下时，第三电动机温度T3可被达到。
特别地，第一电动机温度T1可以高于第二电动机温度T2，第二电动机T2可以高于第三电动机温度T3，并且第一电动机温度T1、第二电动机温度T2、第三电动机温度T3可由重复性实验预先确定。输出限制因素(例如：当前电动机温度)可依据驱动条件进行区分，并且电动机输出可如上文所述进行限制。即，电动机输出可根据基于驱动模式改变的当前电动机温度而进行限制，因此能够改善车辆驱动性能。
同时，根据图4，由于现有技术中的电动机转矩仅当车辆行驶时电动机过热达到预设温度或者更高时才受到限制，因此由于源自电动机排放的热量快速增长使得发动机突然运行，或者由于电动机过热引起的输出限制导致驱动性能劣化。在本发明中，在由于车辆被驱动时电动机达到过热状态导致电动机输出受限之前，发动机可以先运行，且因此电动机输出将会缓慢减少，因此能够防止电动机过热，保证线性制动性能，并且改善起动与加速性能。
本发明参考其示例性实施例进行了详细的描述。然而，本领域技术人员应当理解的是在不违背本发明的原则和精神、不脱离所附权利要求及其等同形式所定义的范围，可对本发明示例性的实施例做出修改。
