Description
技术领域
本发明涉及将在连接与内燃机驱动连结的输入部件和与车轮驱动连结的输出部件的动力传递路径上,从上述输入部件侧开始依次设置了接合装置、旋转电机、以及自动变速器的车辆用驱动装置作为控制对象的控制装置。
背景技术
关于在上述那样的车辆用驱动装置中启动内燃机的情况下的控制技术,例如在下述的专利文献1公开了以下那样的控制装置。即,该控制装置在内燃机停止的状态下将旋转电机的转矩传递到车轮的EV模式下的行驶中有内燃机的启动要求的情况下,执行通过内燃机与旋转电机之间的第一离合器的拖拽转矩摩擦启动停止状态的内燃机,并且在这样的内燃机的启动中,使作为构成变速档的自动变速器的紧固离合器之一的第二离合器滑动的控制。另外,在专利文献1记载了在这样的内燃机的启动中,也可以在由于降档等而变速档移行的情况下,根据在该移行的前后的紧固离合器的变化,使滑动的第二离合器移行。
然而,在上述那样的EV模式的行驶中由驾驶员较大地踩下加速器的情况下,为了能够将较大的转矩传递到车轮,而与内燃机的启动一起进行自动变速器的降档。在这样的状况下,要求根据驾驶员的请求,尽早地将较大的转矩传递到车轮。然而,在上述专利文献1的控制技术中,在内燃机的启动中,旋转电机除了用于车轮的驱动的转矩之外,还需要输出用于使内燃机上升至能够启动的旋转速度的转矩、和用于与自动变速器的降档配合地使内燃机以及旋转电机的旋转速度上升的转矩。由于旋转电机能够输出的转矩有限,所以传递到车轮的转矩相应地减少。因此,不管驾驶员的请求,到内燃机的启动和自动变速器的降档双方完成为止,只能够将与旋转电机的最大转矩相比大幅度地减小的转矩传递到车轮,成为使驾驶员感到车辆的加速较慢的重要因素。
专利文献1:日本特开2007-131070号公报
发明内容
因此,期望即使在从内燃机停止,向车轮传递旋转电机的转矩的状态开始,执行内燃机的启动和自动变速器的降档的情况下,也能够较早地将较大的转矩传递到车轮的技术的实现。
鉴于上述的、将在连接与内燃机驱动连结的输入部件和与车轮驱动连结的输出部件的动力传递路径上,从上述输入部件侧开始依次设置了接合装置、旋转电机、以及自动变速器的车辆用驱动装置作为控制对象的控制装置的特征构成在于,将对上述内燃机进行点火而能够启动的旋转速度设为可启动旋转速度,并将进行向更大的侧变更上述自动变速器的变速比的降档的情况下的该降档的完成后的上述旋转电机的旋转速度设为降档后同步旋转速度,在从上述内燃机停止,上述接合装置被释放,并向上述车轮传递上述旋转电机的转矩的状态开始,执行上述内燃机的启动和上述降档的情况下,使上述接合装置接合使上述内燃机的旋转速度上升至上述可启动旋转速度,在上述内燃机的旋转速度上升至上述可启动旋转速度之后,使上述内燃机点火,然后使上述接合装置释放,在上述内燃机的点火后,通过该内燃机的转矩使该内燃机的旋转速度朝向上述降档后同步旋转速度上升,在使上述接合装置释放之后,使上述旋转电机的旋转速度朝向上述降档后同步旋转速度上升,来执行上述自动变速器的上述降档,在上述降档的完成后使上述接合装置接合。
根据该特征构成,由于在使接合装置接合使内燃机的旋转速度上升至可启动旋转速度之后使接合装置释放,所以能够以使旋转电机从内燃机分离的状态进行用于降档的旋转速度变化。由此,没有内燃机的惯性,相应地能够在早期使旋转电机的旋转速度接近降档后同步旋转速度,能够在早期完成自动变速器的降档。因此,能够在早期以降档后的变速比将未减去用于使内燃机以及旋转电机的旋转速度变化的惯性转矩的旋转电机的转矩传递到车轮。另外,对于内燃机来说,在旋转速度上升至可启动旋转速度并进行点火之后,通过内燃机自身的转矩使旋转速度朝向降档后同步旋转速度上升,所以能够在降档的完成后顺利地使接合装置接合。在接合装置的接合后,也能够以降档后的变速比将内燃机的转矩传递到车轮,所以能够将较大的转矩传递到车轮。

具体实施方式
对本实施方式所涉及的控制装置1进行说明。该控制装置1是将车辆用驱动装置3作为控制对象的控制装置1。成为控制对象的车辆用驱动装置3是用于驱动具备内燃机EG以及旋转电机MG作为车轮W的驱动力源的所谓的混合动力车辆的驱动装置(混合动力车辆用驱动装置)。在本实施方式中,车辆用驱动装置3成为用于驱动并联式的混合动力车辆的并联混合动力车辆用驱动装置。
在以下的说明中,“驱动连结”是指两个旋转构件以能够传递驱动力(转矩)的方式连结的状态。该概念包含两个旋转构件连结为一体旋转的状态、连结为能够经由一个以上的传动部件传递驱动力的状态。这样的传动部件包含以同速或者变速地传递旋转的各种部件(例如,轴、齿轮机构、传送带、链等),也可以包含有选择地传递旋转以及驱动力的接合装置(例如,摩擦接合装置、啮合式接合装置等)。
另外,“旋转电机”作为包含马达(电动机)、发电机(发电器)、以及根据需要实现马达以及发电机双方的功能的电动发电机的任何一个的概念使用。
另外,关于摩擦接合装置的接合的状态,“接合状态”是指在该摩擦接合装置产生传递转矩容量的状态。这里,传递转矩容量是摩擦接合装置能够通过摩擦传递的最大转矩,其大小与相互推压该摩擦接合装置具备的一对接合部件(输入侧接合部件和输出侧接合部件)的压力(接合压)成比例地确定。该“接合状态”包含在一对接合部件间没有旋转速度差(滑动)的“直接连结接合状态”、和有旋转速度差的“滑动接合状态”。另一方面,“释放状态”是指除了一对接合部件间的拖拽转矩以外,在摩擦接合装置未产生传递转矩容量的状态。
如图1所示,在该车辆用驱动装置3中,在连接与内燃机EG驱动连结的输入部件31和与车轮W驱动连结的输出部件36的动力传递路径上,从输入部件31侧开始依次设置有传递接合装置32、旋转电机MG以及自动变速器35。另外,这里,旋转电机MG与自动变速器35之间经由变速输入部件34连结。因此,在本实施方式中,沿着上述动力传递路径,从内燃机EG侧开始依次配置有输入部件31、传递接合装置32、旋转电机MG、变速输入部件34、自动变速器35、以及输出部件36。
输入部件31与内燃机EG驱动连结。内燃机EG是通过内燃机内部的燃料的燃烧进行驱动取出动力的原动机,例如是汽油发动机、柴油发动机、燃气轮机等。输入部件31例如由轴部件(输入轴)构成。输入部件31以一体地旋转的方式与内燃机EG的输出部件亦即内燃机输出部件(曲轴等)驱动连结。因此,输入部件31的旋转速度与内燃机EG的旋转速度Neg基本一致。此外,输入部件31与内燃机输出部件既可以直接连结,也可以经由减振器等其它的部件连结。输入部件31经由传递接合装置32与旋转电机MG驱动连结。
传递接合装置32有选择地连结输入部件31与旋转电机MG。换句话说,传递接合装置32能够状态变化为连结内燃机EG与旋转电机MG之间的状态、和解除了该连结的状态。由此,传递接合装置32作为从具备旋转电机MG以及自动变速器35的车辆用驱动装置3断开内燃机EG的内燃机断开用接合装置发挥作用。在本实施方式中,传递接合装置32是摩擦接合装置,例如能够使用湿式多板离合器等。
旋转电机MG包含固定于作为非旋转部件的壳体的定子、和在该定子的径向内侧被支承为自由旋转的转子。旋转电机MG经由逆变器装置与蓄电装置连接。旋转电机MG从蓄电装置接受电力的供给进行动力运行,或者,使通过内燃机EG的转矩Teg、车辆的惯性力等发电的电力供给至蓄电装置使其蓄电。旋转电机MG的转子以一体旋转的方式与变速输入部件34连结。因此,在本实施方式中,变速输入部件34的旋转速度Nin与旋转电机MG(转子)的旋转速度一致。变速输入部件34例如由轴部件(变速输入轴)构成。与转子一体旋转的变速输入部件34与自动变速器35驱动连结。
在本实施方式中,自动变速器35是有级自动变速器。例如如图2所示,本实施方式的自动变速器35具备多个行星齿轮机构、和多个变速用接合装置35C。在本实施方式中,行星齿轮机构包含双小齿轮型(或者单小齿轮型)的第一行星齿轮装置、拉维娜式第二行星齿轮装置。在变速用接合装置35C包含有离合器C1、C2、C3、C4、制动器B1、B2。在本实施方式中,构成变速用接合装置35C的各离合器C1、C2、C3、C4以及各制动器B1、B2是摩擦接合装置,例如能够使用湿式多板离合器、湿式多板制动器等。此外,也可以在变速用接合装置35C包含有一个或者多个单向离合器,在本例中,包含一个单向离合器F1。
自动变速器35例如能够根据图3所示的工作表,根据各离合器C1、C2、C3、C4以及各制动器B1、B2(或者单向离合器F1)各自的接合的状态,选择性地形成多个变速档的任意一个。例如自动变速器35在第一离合器C1以及第二制动器B2的直接连结接合状态,并且,在其它的变速用接合装置35C的释放状态下,形成第一档(1st)。另外,例如自动变速器35在第一离合器C1以及第一制动器B1的直接连结接合状态,并且,在其它的变速用接合装置35C的释放状态下,形成第二档(2nd)。也能够同样地考虑其它的变速档(3rd~8th)。此外,图3中的“(○)”表示仅在从车轮W侧传递负转矩的状态,即所谓的发动机制动器中或者再生制动中的状态下接合。
自动变速器35基于与形成的变速档对应的变速比对变速输入部件34的旋转速度Nin进行变速并传递到输出部件36。这里,“变速比”是变速输入部件34的旋转速度Nin相对于输出部件36的旋转速度的比,作为将变速输入部件34的旋转速度Nin除以输出部件36的旋转速度的值进行计算。即,随着变速比增大从变速输入部件34传递到输出部件36的旋转较大地减速,随着变速比增大从变速输入部件34传递到输出部件36的转矩被放大来传递。
如图1所示,输出部件36经由差动齿轮装置37,与左右一对的车轮W驱动连结。传递到输出部件36的转矩经由差动齿轮装置37分配并传递到左右两个车轮W。由此,车辆用驱动装置3能够将内燃机EG以及旋转电机MG的一方或者双方的转矩传递到车轮W使车辆行驶。输出部件36例如由轴部件(输出轴)、齿轮机构(输出齿轮)等构成。
控制装置1作为进行上述的车辆用驱动装置3的各部的动作控制的核心发挥作用。在本实施方式中,如图4所示,控制装置1具备统合控制部11、旋转电机控制部12、接合控制部13、启动控制部14、以及启动变速重叠控制部15。通过存储于存储器等存储介质的软件(程序)或者另外设置的运算电路等硬件,或者它们双方构成这些各功能部。各功能部构成为能够相互进行信息的交换。另外,控制装置1构成为能够获取搭载了车辆用驱动装置3的车辆的各部所具备的各种传感器(第一传感器51~第四传感器54)的检测结果的信息。
第一传感器51检测输入部件31以及与该输入部件31一体地旋转的部件(例如,内燃机EG)的旋转速度。第二传感器52检测变速输入部件34以及与该变速输入部件34一体旋转的部件(例如,旋转电机MG)的旋转速度。第三传感器53检测输出部件36的旋转速度,或者,与输出部件36同步旋转的部件(例如,车轮W)的旋转速度。此外,“同步旋转”是指以与基准旋转速度成比例的旋转速度进行旋转。控制装置1能够基于第三传感器53的检测结果计算车速。第四传感器54检测加速器开度。控制装置1能够基于第四传感器54的检测结果计算驾驶员的要求驱动力(要求转矩)。控制装置1构成为除了这些检测结果以外,例如还能够获取制动器操作量、蓄电装置的蓄电量等信息。
统合控制部11进行作为车辆整体统合对内燃机EG、旋转电机MG、传递接合装置32、以及自动变速器35(变速用接合装置35C)等进行的各种控制(转矩控制、旋转速度控制、接合控制等)的控制。统合控制部11基于传感器检测信息(主要是加速器开度以及车速的信息),计算为了车辆(车轮W)的驱动而要求的车辆要求转矩。
另外,统合控制部11基于传感器检测信息(主要是加速器开度、车速、以及蓄电装置的蓄电量的信息),决定行驶模式。在本实施方式中,统合控制部11能够选择的行驶模式包含电动行驶模式(以下,称为“EV模式”。)和混合动力行驶模式(以下,称为“HEV模式”。)。EV模式是从车轮W分离内燃机EG,而将旋转电机MG的转矩Tmg传递到车轮W而使车辆行驶的行驶模式。HEV模式是将内燃机EG以及旋转电机MG双方的转矩传递到车轮W而使车辆行驶的行驶模式。
统合控制部11基于决定的行驶模式、传感器检测信息等,决定对内燃机EG要求的输出转矩(内燃机要求转矩)、对旋转电机MG要求的输出转矩(旋转电机要求转矩)。另外,统合控制部11基于决定的行驶模式、传感器检测信息等,决定传递接合装置32的接合的状态、使自动变速器35形成的目标变速档等。
在本实施方式中,控制装置1(统合控制部11)经由内燃机控制装置20,控制内燃机EG的动作点(输出转矩以及旋转速度)。内燃机控制装置20能够根据车辆的行驶状态切换内燃机EG的转矩控制和旋转速度控制。内燃机EG的转矩控制是对内燃机EG指示目标转矩,使内燃机EG的输出转矩追随该目标转矩的控制。内燃机EG的旋转速度控制是对内燃机EG指示目标旋转速度,以使内燃机EG的旋转速度Neg追随该目标旋转速度的方式决定输出转矩的控制。
旋转电机控制部12控制旋转电机MG的动作点(输出转矩以及旋转速度)。旋转电机控制部12能够根据车辆的行驶状态切换旋转电机MG的转矩控制和旋转速度控制。旋转电机MG的转矩控制是对旋转电机MG指示目标转矩,使旋转电机MG的输出转矩追随该目标转矩的控制。旋转电机MG的旋转速度控制是对旋转电机MG指示目标旋转速度Nt,以使旋转电机MG的旋转速度追随该目标旋转速度Nt的方式决定输出转矩的控制。
接合控制部13控制传递接合装置32的接合的状态、自动变速器35具备的多个变速用接合装置35C(C1、C2、C3、C4、B1、B2)的接合的状态。在本实施方式中,传递接合装置32、多个变速用接合装置35C是液压驱动式的摩擦接合装置。接合控制部13通过经由液压控制装置41控制供给至各传递接合装置32、变速用接合装置35C的液压,来控制传递接合装置32、变速用接合装置35C各自的接合的状态。
各接合装置的接合压与供给至该接合装置的液压的大小成比例地变化。据此,在各接合装置产生的传递转矩容量的大小与供给至该接合装置的液压的大小成比例地变化。而且,各接合装置的接合的状态根据供给的液压被控制为直接连结接合状态、滑动接合状态、以及释放状态的任意一个。液压控制装置41具备用于调整从油泵(未图示)供给的工作油的液压的液压控制阀(线性电磁阀等)。油泵例如可以是被输入部件31或者变速输入部件34等驱动的机械泵,或者通过泵用旋转电机驱动的电动泵等。液压控制装置41通过根据来自接合控制部13的液压指令来调整液压控制阀的开度,而向各接合装置供给与该液压指令对应的液压。
接合控制部13将传递接合装置32的接合的状态控制为形成由统合控制部11决定的行驶模式。接合控制部13例如在EV模式的形成时将传递接合装置32控制为释放状态,在HEV模式的形成时将传递接合装置32控制为直接连结接合状态。另外,在从EV模式向HEV模式的移行中,将传递接合装置32控制为滑动接合状态。
另外,接合控制部13将多个变速用接合装置35C(C1、C2、C3、C4、B1、B2)各自的接合的状态控制为形成由统合控制部11决定的目标变速档。接合控制部13将与目标变速档对应的两个变速用接合装置35C控制为直接连结接合状态,并且将它们以外的全部的变速用接合装置35C控制为释放状态(参照图3)。另外,接合控制部13在车辆的行驶中变更了目标变速档的情况下,基于在变更前后的目标变速档分别应该成为直接连结接合状态的变速用接合装置35C的差分,将特定的变速用接合装置35C从直接连结接合状态控制为释放状态,并且将其它的特定的变速用接合装置35C从释放状态控制为接合状态。这样,将变更成为直接连结接合状态的变速用接合装置35C的动作称为变速动作。“变速动作”有向减小变速比的一侧进行变更的“升档”、和向增大变速比的一侧进行变更的“降档”。
在以下的说明中,将在变速动作中从接合状态变为释放状态的变速用接合装置35C称为“释放侧接合装置35R”,并将从释放状态变为接合状态(紧固)的变速用接合装置35C称为“紧固侧接合装置35A”。另外,将在变更前后的目标变速档均为直接连结接合状态,在变速动作中维持为直接连结接合状态的变速用接合装置35C称为“直接连结维持接合装置35S”。参照图3,例如在进行从第四档(4th)向第三档(3rd)的变速动作(降档)的情况下,第一离合器C1成为直接连结维持接合装置35S,第四离合器C4成为释放侧接合装置35R,第三离合器C3成为紧固侧接合装置35A。另外,例如若为从第五档(5th)向第六档(6th)的变速动作(升档),则第二离合器C2成为直接连结维持接合装置35S,第一离合器C1成为释放侧接合装置35R,第四离合器C4成为紧固侧接合装置35A。关于其它的变速档间的变速动作,也能够同样地考虑。
启动控制部14在从EV模式向HEV模式的模式移行时,不伴随降档的情况下,执行通常的内燃机启动控制。在EV模式中,成为内燃机EG停止,传递接合装置32被释放,旋转电机MG的转矩Tmg传递到车轮W的状态。在该状态下,例如若因驾驶员的加速器操作而车辆要求转矩增大,或者蓄电装置的蓄电量降低,而有向HEV模式的模式移行要求(内燃机启动要求),则启动控制部14执行内燃机启动控制。
在本实施方式中,启动控制部14在通常的内燃机启动控制中,与接合控制部13配合地使多个变速用接合装置35C中的一个成为滑动接合状态。这里,成为滑动接合状态的变速用接合装置35C是在假定从该状态开始进行变速动作的情况下成为直接连结维持接合装置35S的可能性较低(即,成为释放侧接合装置35R的可能性较高)的变速用接合装置35C。这样一来,有在其后在内燃机启动控制的执行中有变速要求的情况下,能够迅速地推进变速动作这样的优点。这里,启动控制部14根据内燃机启动控制的开始时的变速档,使不为成为直接连结维持接合装置35S的可能性较高的变速用接合装置35C(在本例中为第一离合器C1或者第二离合器C2)的变速用接合装置35C成为滑动接合状态。
另外,在内燃机启动控制中,启动控制部14与旋转电机控制部12配合地通过旋转电机MG的旋转速度控制使该旋转电机MG的旋转速度(变速输入部件34的旋转速度Nin)上升。例如启动控制部14通过旋转电机MG的旋转速度控制使该旋转电机MG的旋转速度与同步旋转速度相比上升。这里,同步旋转速度是根据当前的变速档的变速比和输出部件36的旋转速度(或者与其同步旋转的车轮W的旋转速度)决定的速度。具体而言,对输出部件36的旋转速度乘以当前的变速档的变速比来计算同步旋转速度。启动控制部14将旋转电机MG的旋转速度控制中的目标旋转速度Nt设定为比同步旋转速度高预先决定的转速差的旋转速度,使旋转电机MG的旋转速度与同步旋转速度相比上升。考虑能够使释放侧接合装置35R稳定地成为滑动接合状态的旋转速度差预先决定该转速差,例如能够在100~300〔rpm〕等的范围内适当地设定。
并且,在内燃机启动控制中,启动控制部14与接合控制部13配合地使传递接合装置32成为滑动接合状态。这样一来,通过经由滑动接合状态的传递接合装置32从旋转电机MG侧传递到内燃机EG侧的旋转电机MG的转矩Tmg,使内燃机EG的旋转速度上升。然后,在内燃机EG的旋转速度Neg变为可启动旋转速度Nig以上之后,启动控制部14与内燃机控制装置20配合对内燃机EG进行点火使内燃机EG启动。可启动旋转速度Nig是通过对内燃机EG进行点火而内燃机EG能够开始(启动)自主运转的旋转速度。在本实施方式中,在通常的内燃机启动控制中,在释放侧接合装置35R的滑动接合状态下启动内燃机EG,所以能够避免内燃机EG的初爆时的转矩变动直接传递到车轮W。由此,能够降低伴随内燃机EG的启动的冲击(启动冲击)。
另一方面,在从EV模式向HEV模式的模式移行时,伴随降档的情况下,执行通过启动变速重叠控制部15的启动变速重叠控制。在该启动变速重叠控制中,执行与上述的通常的内燃机启动控制不同的控制。启动变速重叠控制是在从内燃机EG停止,传递接合装置32被释放,旋转电机MG的转矩Tmg传递到车轮W的状态,即从EV模式开始,执行内燃机EG的启动和自动变速器35的降档的情况下进行的控制。这里,并行地执行用于内燃机EG的启动的内燃机EG的旋转速度Neg的变化和用于自动变速器35的降档的变速用接合装置35C的接合压的变化。启动变速重叠控制部15与内燃机控制装置20、旋转电机控制部12、以及接合控制部13配合地执行启动变速重叠控制。在该控制中,启动变速重叠控制部15将传递接合装置32接合并在内燃机EG的旋转速度Neg变为可启动旋转速度Nig以上之后,释放传递接合装置32而断开内燃机EG,仅利用旋转电机MG引起旋转变化,其后进行自动变速器35的降档。由此,迅速地完成降档,成为能够以降档后的变速比将旋转电机MG的转矩Tmg传递到车轮W的状态。另外内燃机EG在可启动旋转速度Nig以上进行点火,之后通过自身的转矩使旋转速度Neg朝向降档后同步旋转速度Na上升,使其与降档后同步旋转速度Na同步,其后使传递接合装置32接合。然后,在传递接合装置32接合之后,内燃机EG的转矩Teg也能够以降档后的变速比传递到车轮W,所以能够将更大的转矩传递到车轮W。
这里,作为相对于本实施方式的启动变速重叠控制的比较例,对在执行内燃机EG的启动控制和自动变速器35的降档的情况下,将传递接合装置32接合而启动内燃机EG后,将传递接合装置32保持为接合状态的状态下进行降档的动作的例子进行说明。图8是该比较例的时序图。在该时序图中,“Ti”是从作为车轮W的驱动力源的旋转电机MG以及内燃机EG传递到变速输入部件34的变速输入传递转矩。“N”是旋转速度,这里示出变速输入部件34(旋转电机MG)的旋转速度Nin和内燃机EG的旋转速度Neg。“T”是转矩,这里示出旋转电机MG的转矩Tmg和内燃机EG的转矩Teg。“P”是接合装置的接合压,这里示出传递接合装置32的接合压P1、释放侧接合装置35R的接合压P2、以及紧固侧接合装置35A的接合压P3。此外,在图8中,作为各接合装置的接合压示出液压指令。
如该图8所示,在比较例中,在从EV模式进行内燃机EG的启动和自动变速器35的降档的情况下,首先开始传递接合装置32的接合准备(t31)。在本例中,此时的变速输入传递转矩Ti为比较小的转矩Ti1。另外其后,利用使变速输入部件34的旋转速度Nin追随目标旋转速度Nt的旋转速度控制来控制旋转电机MG。在该时刻,旋转电机MG被控制为使变速前同步旋转速度Nb成为目标旋转速度Nt。这里,变速前同步旋转速度Nb是根据降档前的当前的变速档的变速比和输出部件36的旋转速度(或者与其同步旋转的车轮W的旋转速度)决定的速度。然后,若传递接合装置32的接合压P1逐渐上升而传递接合装置32开始滑动接合(t32),则经由传递接合装置32传递到内燃机EG侧的转矩增加,所以相应地旋转电机MG的转矩Tmg增加,但变速输入传递转矩Ti(=Ti1)被维持。
其后,使释放侧接合装置35R的接合压P2降低(t33)。此外,释放侧接合装置35R在从开始用于降档的变速输入部件34的旋转速度Nin的变化到该旋转速度Nin达到降档后同步旋转速度Na为止(t39)的期间,为滑动接合状态。另外,随着传递接合装置32的滑动接合所带来的传递转矩的上升,内燃机EG的旋转速度Neg开始上升(t34)。在本例中,此时旋转电机MG的转矩Tmg达到最大转矩Tmg·Max,但只能够向车轮W传递减去用于使内燃机EG的旋转速度Neg上升的内燃机启动转矩A1后的转矩A3,所以变速输入传递转矩Ti停留在Ti2。
接下来,开始紧固侧接合装置35A的接合准备(t35)。其后,若内燃机EG的旋转速度Neg变为可启动旋转速度Nig以上,则对内燃机EG进行点火使内燃机EG启动。由此,内燃机EG的转矩Teg开始上升(t36)。另外,内燃机EG的旋转速度Neg也继续上升。然后,在内燃机EG的旋转速度Neg与变速输入部件34的旋转速度Nin同步时(t37),传递接合装置32成为直接连结接合状态。其后,使传递接合装置32的接合压P1上升至用于维持直接连结接合状态的完全接合压。另外,通过旋转电机MG的转矩Tmg,使一体旋转的内燃机EG以及变速输入部件34(旋转电机MG)的旋转速度Neg、Nin朝向降档后同步旋转速度Na上升(t37~t39)。在本例中,在此期间也是旋转电机MG的转矩Tmg成为最大转矩Tmg·Max,但只能够对车轮W传递减去用于使内燃机EG以及变速输入部件34(旋转电机MG)的旋转速度Neg、Nin上升的变速用旋转变化转矩A2后的转矩A3,所以变速输入传递转矩Ti继续停留在Ti2。
接下来,若内燃机EG以及变速输入部件34(旋转电机MG)的旋转速度Neg、Nin相对于降档后同步旋转速度Na接近至设定旋转速度差(t38),则使紧固侧接合装置35A的接合压P3的上升开始。然后,在内燃机EG以及变速输入部件34(旋转电机MG)的旋转速度Neg、Nin与降档后同步旋转速度Na同步时(t39),紧固侧接合装置35A成为直接连结接合状态。由此,移至混合动力模式。在本例中,在这里结束旋转电机MG的旋转速度控制。其后,使紧固侧接合装置35A的接合压P3朝向用于维持直接连结接合状态的完全接合压上升,并且使作为滑动接合状态的释放侧接合装置35R的接合压P2逐渐朝向完全释放压降低。另外,在紧固侧接合装置35A成为直接连结接合状态之后,使内燃机EG的转矩Teg上升(t39~t40)。由此,变速输入传递转矩Ti从Ti2上升至Ti4。另外在本例中,随着内燃机EG的转矩Teg的上升,使旋转电机MG的转矩Tmg降低。通过以上完成内燃机EG的启动和自动变速器35的降档,其后,将内燃机EG的转矩Teg传递至车轮W使车辆行驶。此外,在该状态下,旋转电机MG根据需要进行发电,或者动力运行来进行转矩辅助。
如以上那样,在比较例的控制中,到内燃机EG的启动和自动变速器35的降档双方完成为止,对于传递到变速输入部件34的变速输入传递转矩Ti来说,只能够将和与旋转电机MG的最大转矩Tmg·Max所对应的转矩相比大幅度地减小的转矩Ti2传递到变速输入部件34,有使驾驶员感到车辆的加速较慢的可能性。但是,通过进行本实施方式所涉及的启动变速重叠控制,如以下所说明的那样,能够快速地将较大的转矩传递到车轮W。
图5是表示内燃机启动控制的处理顺序的流程图,图6是表示本实施方式所涉及的启动变速重叠控制的处理顺序的流程图。另外,图7是表示该启动变速重叠控制的一个例子的时序图。在该图7的时序图也示出与图8相同的指标。
如图5所示,控制装置1在内燃机EG停止,传递接合装置32被释放,旋转电机MG的转矩Tmg传递到车轮W的状态亦即EV模式中(#1),有内燃机EG的启动要求的情况下(#2:是),判断是否也有自动变速器35的降档的要求(#3)。而且,在有内燃机EG的启动要求和降档的要求双方的情况下,执行启动变速重叠控制(#4)。另一方面,在仅有内燃机EG的启动要求,没有降档的要求的情况下,执行上述的通常的内燃机启动控制(#5)。
接下来,使用图6的流程图以及图7的时序图,对本实施方式所涉及的启动变速重叠控制的例子进行说明。在该启动变速重叠控制中,概略而言,首先使传递接合装置32接合而使内燃机EG的旋转速度上升至可启动旋转速度Nig,并在内燃机EG的旋转速度上升至可启动旋转速度Nig之后,使内燃机EG点火,其后使传递接合装置32释放。然后,在内燃机EG的点火后,通过该内燃机EG的转矩Teg使该内燃机EG的旋转速度朝向降档后同步旋转速度Na上升。另外,在使传递接合装置32释放之后,使旋转电机MG的旋转速度朝向降档后同步旋转速度Na上升,执行自动变速器35的降档。然后,在降档的完成后使传递接合装置32接合。
在启动变速重叠控制中,具体而言,首先开始传递接合装置32的接合准备(t11)。在本例中,此时的变速输入传递转矩Ti是比较小的转矩Ti1。另外其后,利用使变速输入部件34的旋转速度Nin追随目标旋转速度Nt的旋转速度控制来控制旋转电机MG(#11)。在该时刻,旋转电机MG被控制为将变速前同步旋转速度Nb作为目标旋转速度Nt。然后,传递接合装置32的接合压P1逐渐上升而传递接合装置32开始滑动接合(t12、#12)。由此,经由传递接合装置32传递到内燃机EG侧的转矩增加,所以相应地旋转电机MG的转矩Tmg增加,但变速输入传递转矩Ti(=Ti1)被维持。
其后,开始用于降档的自动变速器35的变速用接合装置35C的接合压的变化(#13)。具体而言,首先,使释放侧接合装置35R的接合压P2的降低开始(t13)。此外,释放侧接合装置35R在从开始用于降档的变速输入部件34的旋转速度Nin的上升到该旋转速度Nin达到降档后同步旋转速度Na为止(t18)的期间,为滑动接合状态。这里,紧固侧接合装置35A成为滑动接合状态为止的期间(t13~t17),即释放侧接合装置35R进行向车轮W的转矩传递的期间的、使释放侧接合装置35R的接合压P2降低的期间相当于降档的准备期间。另外,随着传递接合装置32的滑动接合所带来的传递转矩的上升,内燃机EG的旋转速度Neg开始上升(t14)。在本例中,与使传递接合装置32接合使内燃机EG的旋转速度Neg上升至可启动旋转速度Nig的期间重叠地作为降档的准备使释放侧接合装置35R的接合压降低。此时虽然旋转电机MG的转矩Tmg达到最大转矩Tmg·Max,但只能够向车轮W传递减去用于使内燃机EG的旋转速度Neg上升的内燃机启动转矩A1后的转矩A3,所以变速输入传递转矩Ti停留在Ti2。
接下来,开始紧固侧接合装置35A的接合准备(t15)。其后,若内燃机EG的旋转速度Neg变为可启动旋转速度Nig以上(#14、t16),则对内燃机EG进行点火使内燃机EG启动(#15)。另外,在该启动变速重叠控制中,与上述的比较例不同,在内燃机EG的旋转速度上升至可启动旋转速度Nig之后,使传递接合装置32的接合压P1降低,使传递接合装置32释放(#16、t16)。然后,通过旋转电机MG的转矩Tmg,使变速输入部件34(旋转电机MG)的旋转速度Nin朝向降档后同步旋转速度Na上升(#17、t16~t18)。此时,由于释放传递接合装置32,所以能够以从内燃机EG分离变速输入部件34以及旋转电机MG的状态,进行用于降档的变速输入部件34的旋转速度Nin的上升。由此,没有内燃机EG的惯性,相应地能够在早期使变速输入部件34的旋转速度Nin接近降档后同步旋转速度Na,能够在早期完成自动变速器35的降档。此外,由于在该降档中,也是虽然旋转电机MG的转矩Tmg成为最大转矩Tmg·Max,但只能够对车轮W传递减去用于使变速输入部件34以及旋转电机MG的旋转速度Nin上升的变速用旋转变化转矩A2后的转矩A3,所以变速输入传递转矩Ti继续停留在Ti2。
接下来,若变速输入部件34(旋转电机MG)的旋转速度Nin相对于降档后同步旋转速度Na接近至设定旋转速度差,则使紧固侧接合装置35A的接合压P3的上升开始(t17)。然后,在变速输入部件34(旋转电机MG)的旋转速度Nin与降档后同步旋转速度Na同步时(#19:是、t18),紧固侧接合装置35A成为直接连结接合状态。其后,进一步使紧固侧接合装置35A的接合压P3朝向用于维持直接连结接合状态的完全接合压上升,并且使作为滑动接合状态的释放侧接合装置35R的接合压P2逐渐朝向完全释放压降低。由此,用于降档的自动变速器35的接合装置的接合压的变化结束(#20),自动变速器35的降档完成。在本例中,在此结束旋转电机MG的旋转速度控制,并开始使旋转电机MG的转矩Tmg追随目标转矩的转矩控制。即,在本实施方式中,在从为了使内燃机EG的旋转速度上升而开始使传递接合装置32接合(t12)开始到降档完成(t18)为止的期间,执行使旋转电机MG追随目标旋转速度Nt的旋转速度控制。由此,能够不管传递接合装置32的接合所引起的转矩变动、用于降档的旋转电机MG的旋转速度的上升所引起的转矩变动,而稳定地使旋转电机MG的旋转速度与目标旋转速度Nt一致。因此,能够使该期间的车辆的行驶状态稳定。
然后,在变速输入部件34(旋转电机MG)的旋转速度Nin的变化结束之后,能够将未减去用于使变速输入部件34以及旋转电机MG的旋转速度Nin上升的变速用旋转变化转矩A2的旋转电机MG的最大转矩Tmg·Max传递到变速输入部件34。因此,变速输入传递转矩Ti从Ti2增加至Ti3。这样一来,根据本实施方式所涉及的启动变速重叠控制,能够在早期以降档后的变速比将未减去用于使内燃机EG以及旋转电机MG的旋转速度变化的惯性转矩的旋转电机MG的转矩Tmg传递到车轮W。
另外,在内燃机EG的点火后,内燃机EG的转矩Teg开始上升。而且,通过该内燃机EG的转矩Teg,使内燃机EG的旋转速度Neg朝向降档后同步旋转速度Na上升(#18、t16~t20)。因此,在本例中,在降档的完成后,内燃机EG的旋转速度也通过该内燃机EG的转矩Teg朝向降档后同步旋转速度Na上升(t18~t20)。这样,通过内燃机EG的转矩Teg,进行内燃机EG的旋转速度Neg的向降档后同步旋转速度Na的旋转配合(同步),从而能够在降档的完成后顺利地使传递接合装置32接合。而且,在该期间,再次开始暂时成为释放状态的传递接合装置32的接合准备(t19)。
在本实施方式中,在降档的完成后,在内燃机EG的旋转速度比降档后同步旋转速度Na高之后使传递接合装置32接合。这样一来,能够抑制在使传递接合装置32接合时负转矩传递到车轮W侧。因此,能够抑制在加速中的车辆产生减速方向的冲击。因此,以内燃机EG的旋转速度Neg超过降档后同步旋转速度Na之后接近降档后同步旋转速度Na的方式,进行内燃机EG的旋转速度控制。这里,若内燃机EG的旋转速度Neg接近降档后同步旋转速度Na,则使内燃机EG的转矩Teg降低减缓内燃机EG的旋转速度Neg的变化(t20),使该旋转速度Neg缓慢接近降档后同步旋转速度Na(t20~t21)。另外,在内燃机EG的旋转速度Neg超过降档后同步旋转速度Na之后(#21:是、t20),使传递接合装置32的接合压P1逐渐上升,使传递接合装置32的滑动接合开始(#22、t20~t21)。通过以上,使内燃机EG的旋转速度Neg与降档后同步旋转速度Na同步,并使传递接合装置32为直接连结接合状态(t21)。如上述那样,在本实施方式中,在开始暂时成为释放状态的传递接合装置32的接合的时刻,降档完成而紧固侧接合装置35A成为直接连结接合状态。因此,在本实施方式中,在通过降档而紧固侧接合装置35A成为直接连结接合状态之后,使传递接合装置32为直接连结接合状态。另外在本例中,与使传递接合装置32的滑动接合开始配合地(#22、t20),使内燃机EG的转矩Teg上升(#23)。由此,变速输入传递转矩Ti从Ti3逐渐上升至Ti4(t20~t22)。另外在本例中,随着内燃机EG的转矩Teg的上升,使旋转电机MG的转矩Tmg降低。
在本实施方式中,在从通过使传递接合装置32接合而内燃机EG的旋转速度开始上升(t14),到在降档的完成后通过传递接合装置32的接合开始向输出部件36传递内燃机EG的转矩Teg为止(t20)的期间,旋转电机MG输出最大转矩Tmg·Max。由此,能够缩短到使内燃机EG的旋转速度上升至可启动旋转速度Nig,其后使旋转电机MG的旋转速度朝向降档后同步旋转速度Na上升完成自动变速器35的降档为止的期间。另外,在降档的完成后,能够将相当于旋转电机MG的最大转矩Tmg·Max的转矩Ti3传递到变速输入部件34。
其后,使传递接合装置32的接合压P1上升至用于维持直接连结接合状态的完全接合压(#24、t22)。由此,移至混合动力模式。在传递接合装置32的接合后,也能够以降档后的变速比向车轮W传递内燃机EG的转矩Teg,所以能够将较大的转矩Ti4传递到车轮W。此外,在该状态下,旋转电机MG根据需要进行发电,或者动力运行来进行转矩辅助。
以上结束启动变速重叠控制。
〔其它的实施方式〕

〔上述实施方式的概要〕
以下,对在上述中说明的控制装置1的概要进行说明。
该控制装置(1)将在连接与内燃机(EG)驱动连结的输入部件(31)和与车轮(W)驱动连结的输出部件(36)的动力传递路径上,从上述输入部件(31)侧开始依次设置有接合装置(32)、旋转电机(MG)、以及自动变速器(35)的车辆用驱动装置(3)作为控制对象,将对上述内燃机(EG)进行点火而能够启动的旋转速度设为可启动旋转速度(Nig),并将进行向更大侧变更上述自动变速器(35)的变速比的降档的情况下的该降档的完成后的上述旋转电机(MG)的旋转速度(Nin)设为降档后同步旋转速度(Na),在从上述内燃机(EG)停止,上述接合装置(32)被释放,并向上述车轮(W)传递上述旋转电机(MG)的转矩(Tmg)的状态开始,执行上述内燃机(EG)的启动和上述降档的情况下,使上述接合装置(32)接合使上述内燃机(EG)的旋转速度(Neg)上升至上述可启动旋转速度(Nig),在上述内燃机(EG)的旋转速度(Neg)上升至上述可启动旋转速度(Nig)之后,使上述内燃机(EG)点火,然后使上述接合装置(32)释放,在上述内燃机(EG)的点火后,通过该内燃机(EG)的转矩(Teg)使该内燃机(EG)的旋转速度(Neg)朝向上述降档后同步旋转速度(Na)上升,在使上述接合装置(32)释放之后,使上述旋转电机(MG)的旋转速度(Nin)朝向上述降档后同步旋转速度(Na)上升,来执行上述自动变速器的上述降档,在上述降档的完成后使上述接合装置(32)接合。
根据该构成,在使接合装置(32)接合使内燃机(EG)的旋转速度(Neg)上升至可启动旋转速度(Nig)之后使接合装置(32)释放,所以能够以从内燃机(EG)分离旋转电机(MG)的状态进行用于降档的旋转速度变化。由此,没有内燃机(EG)的惯性,相应地能够在早期使旋转电机(MG)的旋转速度(Nin)接近降档后同步旋转速度(Na),能够在早期完成自动变速器(35)的降档。因此,能够在早期以降档后的变速比将未减去用于使内燃机(EG)以及旋转电机(MG)的旋转速度(Nin)变化的惯性转矩的旋转电机(MG)的转矩(Tmg)传递到车轮(W)。另外,对于内燃机(EG)来说,在旋转速度上升到可启动旋转速度(Nig)而使其点火之后,通过内燃机(EG)自身的转矩使旋转速度朝向降档后同步旋转速度(Na)上升,所以能够在降档的完成后顺利地使接合装置(32)接合。在接合装置(32)的接合后,也能够以降档后的变速比将内燃机(EG)的转矩(Teg)传递到车轮(W),所以能够将较大的转矩传递到车轮(W)。
这里,优选在从为了使上述内燃机(EG)的旋转速度(Neg)上升而开始使上述接合装置(32)接合开始到上述降档完成为止的期间,执行使上述旋转电机(MG)追随目标旋转速度(Nt)的旋转速度控制。
根据该构成,能够不管接合装置(32)的接合所引起的转矩变动、用于降档的旋转电机(MG)的旋转速度(Nin)的上升所引起的转矩变动,而稳定地使旋转电机(MG)的旋转速度(Nin)与目标旋转速度(Nt)一致。因此,能够使该期间的车辆的行驶状态稳定。
另外,优选在从由于使上述接合装置(32)接合而上述内燃机(EG)的旋转速度(Neg)开始上升到在上述降档的完成后通过上述接合装置(32)的接合而上述内燃机(EG)的转矩(Teg)开始传递到上述输出部件(36)为止的期间,上述旋转电机(MG)输出最大转矩(Tmg·Max)。
根据该构成,能够缩短到使内燃机(EG)的旋转速度(Neg)上升至可启动旋转速度(Nig),其后使旋转电机(MG)的旋转速度(Nin)朝向降档后同步旋转速度(Na)上升完成自动变速器(35)的降档为止的期间。另外,在降档的完成后,能够将旋转电机(MG)的最大转矩(Tmg·Max)传递到车轮(W)。
另外,优选在上述降档的完成后,在上述内燃机(EG)的旋转速度(Neg)变得比上述降档后同步旋转速度(Na)高之后使上述接合装置(32)接合。
根据该构成,能够抑制在使接合装置(32)接合时对车轮(W)侧传递负转矩。因此,能够抑制在加速中的车辆产生减速方向的冲击。
另外,优选在上述自动变速器(35)具备的多个变速用接合装置(35C)中,将通过上述降档从接合状态变化为释放状态的上述变速用接合装置(35C)设为释放侧接合装置(35R),与使上述接合装置(32)接合使上述内燃机(EG)的旋转速度(Neg)上升至上述可启动旋转速度(Nig)的期间重叠地使上述自动变速器(35)的释放侧接合装置(35R)的接合压(P2)降低,作为上述降档的准备。
根据该构成,能够利用使内燃机(EG)的旋转速度(Neg)上升至可启动旋转速度(Nig)的期间,使释放侧接合装置(35R)的接合压(P2)降低。因此,能够在启动内燃机(EG)并使接合装置(32)释放之后,迅速地执行降档。由此,能够迅速地以降档后的变速比将旋转电机(MG)的转矩(Tmg)传递到车轮(W)。
另外,优选在上述自动变速器(35)具备的多个变速用接合装置(35C)中,将通过上述降档从释放状态变化为接合状态的上述变速用接合装置(35C)设为紧固侧接合装置(35A),在通过上述降档而上述紧固侧接合装置(35A)成为直接连结接合状态之后,使上述接合装置(32)为直接连结接合状态。
根据该构成,在降档完成后使接合装置(32)接合,所以能够在启动内燃机(EG)之后,以降档后的变速比将内燃机(EG)的转矩(Teg)适当地传递到车轮(W)。
本公开所涉及的技术能够合适地利用于将在连接与内燃机驱动连结的输入部件和与车轮驱动连结的输出部件的动力传递路径上,从上述输入部件侧开始依次设置有接合装置、旋转电机、以及自动变速器的车辆用驱动装置作为控制对象的控制装置。
