Abstract
本发明涉及一种用于控制混合动力电动车辆的转矩干预的***和方法,所述混合动力电动车辆包括作为动力源的电动机和发动机,所述***包括:驱动信息检测器,检测所述车辆的运行状态和所述车辆的驾驶员的所需信息;变速器控制单元(TCU),基于来自所述驱动信息检测器的信号,在所述车辆换挡时,请求转矩减少;牵引力控制***(TCS),为了防止所述车辆的车轮打滑,通过输出干预转矩,请求转矩减少;以及控制器,当从所述TCU或所述TCS接收所述转矩减少请求时,通过将请求转矩减少的量划分给所述发动机和所述电动机,来控制转矩干预,其中当在所述转矩干预之前所述电动机的状态是辅助状态时,所述控制器首先减少电动机辅助转矩,当在转矩干预之前所述电动机的所述状态是充电状态时,保持电动机充电转矩,并且按所述发动机的可用的减少范围和所述电动机的可用的减少范围的比例来划分额外的减少需求。
Description
技术领域
本公开一般涉及用于控制混合动力电动车辆的转矩干预的***和方法。更特别地,本公开涉及用于控制混合动力电动车辆的转矩干预的***和方法,当请求转矩干预时,通过考虑电动机状态和可用的减少范围的比率,该***和方法划分请求转矩减少的量。
背景技术
一般都知道,混合动力电动车辆由从燃料燃烧产生转矩的发动机和从电池组产生转矩的电动电动机驱动。混合动力电动车辆通常包括用于控制混合动力电动车辆的发动机操作的混合控制单元(HCU)、用于控制发动机的操作的发动机控制单元(ECU)、用于控制驱动电动机的操作的电动机控制单元(MCU)、用于控制变速器的操作的变速器控制单元(TCU)和用于管理电池的状况的电池管理***(BMS)。另外,牵引力控制***(TCS)可以被安装在混合动力电动车辆内,所述牵引力控制***(TCS)是用于在启动或加速时通过控制刹车和发动机来防止车轮打滑且提高驱动稳定性的安全***。
当TCU或TCS请求转矩减少时,混合动力电动车辆通常实行转矩干预控制以将请求转矩减少的量划分给发动机和电动机。例如,图1是示出用于控制首先减少发动机转矩且另外相对于不足量减少电动机转矩的混合动力电动车辆的转矩干预的传统方法的图。然而,当持续请求转矩减少时,电池的充电的状态(SOC)可被耗尽,并且电动机的功率性能可能会恶化。
图2是示出用于控制首先减少电动机转矩且另外相对于不足量减少发动机转矩的混合动力电动车辆的转矩干预的传统方法的图。然而,即使请求转矩干预,发动机转矩也不改变,可过度发生发动机噪声,并且噪声、振动和刺耳性(NVH)性能可能会恶化。
在该背景技术部分公开的上述信息仅用于增强本公开的背景的理解,并且因此,它可以包含不构成在该国家中对于本领域普通技术人员来说已知的相关技术的信息。
发明内容
本公开致力于提供用于控制混合动力电动车辆的转矩干预的***和方法。当请求转矩干预时,根据电动机状态和可用的减少范围的比率通过划分请求转矩减少的量,该转矩干预***和方法具有确保电池SOC和NVH性能的优势。

为了本公开的目的,如上所述的混合***的详细解释是不必要的且将被省略。
图4是根据本公开的实施例用于控制混合动力电动车辆的转矩干预的***的方框图。
如图4所示,根据本公开用于控制混合动力电动车辆的转矩干预的***包括驱动信息检测器30、TCU 16、TCS 32、控制器11、发动机20和电动机24。
可以由ECU 12和MCU14实行将在下面描述的根据本公开的实施例在用于控制混合动力电动车辆的转矩干预的方法中的一些过程,并且可以由HCU 10实行一些其他过程。因此,为了描述方便,在该说明书和权利要求书中,在混合动力电动车辆中提供的很多控制器,诸如ECU 12、MCU 14和HCU 10在本文是指控制器11。
本公开的实施例所应用于的混合动力电动车辆包括至少一个发动机20和至少一个电动机24。另外,混合动力电动车辆提供驱动模式,在该驱动模式中,发动机20和电动机24独立地操作,或同时为动力源。为了这个目的,发动机离合器被布置在发动机20和电动机24之间以选择性地连接发动机20和电动机24。
驱动信息检测器30通过从检测车辆速度的车辆速度传感器、检测电动机速度的电动机速度传感器、检测发动机速度的发动机速度传感器、检测油门踏板的位置值的油门踏板位置传感器(APS)、检测制动踏板的位置值的制动踏板位置传感器(BPS)和检测电池的充电状态的电池管理***(BMS)接收信号,检测混合动力电动车辆的运行状态和驾驶员的所需信息。
控制器11可以基于来自驱动信息检测器30的信号,依据发动机离合器22的接合,确定混合动力电动车辆是否处于电动车辆(EV)模式或混合动力电动车辆(HEV)模式。
为了可靠的驾驶性能,在换挡时,TCU 16向控制器11请求转矩减少。
当因为混合动力电动车辆在滑路上出发或加速车轮发生自旋时,TCS 32通过输出干预转矩请求转矩减少。
当从TCU 16或TCS 32接收转矩减少请求时,控制器11实行转矩干预控制以将请求转矩减少的量划分给发动机20和电动机24。
例如,图5是示出根据同时减少发动机转矩和电动机转矩的用于控制混合动力电动车辆的转矩干预的方法的转矩的图。如图5所示,当请求混合动力电动车辆的转矩减少时,控制器11实行以相同的比例同时减少发动机转矩和电动机转矩的转矩干预控制。
同时减少发动机转矩和电动机转矩的方法与传统的方法相比较可以降低发动机噪声;然而,当持续请求转矩减少时,电池SOC可以被耗尽。
为了解决该问题,根据本公开的实施例,控制器11确认在转矩干预之前电动机24的状态(即,“电动机状态”),并且根据在转矩干预之前电动机状态将请求转矩减少的量划分给发动机20和电动机24。即,当在转矩干预之前电动机状态是辅助状态时,控制器11首先减少电动机辅助转矩。另一方面,当在转矩干预之前电动机状态是充电状态时,控制器11保持电动机充电转矩。之后,控制器11执行转矩干预控制,该转矩干预控制按发动机的可用的减少范围和电动机的可用的减少范围的比例来划分额外的减少需求。
将参考图6和图7更详细地描述根据本公开的实施例由控制器11的转矩干预控制。
图6是示出当电动机状态是辅助状态时根据本公开的实施例的用于控制混合动力电动车辆的转矩干预的方法所应用于的转矩的图。
如图6所示,当从TCU 16或TCS 32接收转矩减少请求时,根据本公开控制器11确认在转矩干预之前的电动机状态。
当在转矩干预之前电动机状态是辅助状态,控制器11首先减少电动机辅助转矩直到电动机辅助转矩被用尽。如果由电动机辅助转矩不满足请求转矩减少的量,则控制器11按发动机的可用的减少范围和电动机的可用的减少范围的比例划分额外的减少需求。此时,发动机20可以被控制由0转矩到在转矩干预之前的发动机转矩,所以发动机的可用的减少范围可以被设置为从在转矩干预之前的发动机转矩到0转矩。
相反,电动机24可以被控制从充电极限到0转矩,所以电动机的可用的减少范围可以被设置为从0转矩到充电极限。另外,如图6所示,在发动机20和电动机24之间的可用的减少比率被确定为2:1。因此,控制器11首先减少电动机辅助转矩,并且根据2:1的可用的减少比率划分额外的减少需求。
图7是示出当电动机状态是充电状态时根据本公开的实施例的用于控制混合动力电动车辆的转矩干预的方法所应用于的转矩的图。
如图7所示,当在转矩干预之前电动机状态是充电状态时,根据本公开的实施例控制器11保持电动机充电转矩,并且按发动机的可用的减少范围和电动机的可用的减少范围的比例来划分请求转矩减少的量。
此时,发动机20可以被控制从0转矩到在转矩干预之前的发动机转矩,所以发动机的可用的减少范围可以被设置为从在转矩干预之前的发动机转矩到0转矩。另一方面,电动机24可以被控制从充电极限到在转矩干预之前的充电转矩,所以电动机的可用的减少范围可以被设置为从在转矩干预之前的充电转矩到充电极限。
另外,如图7所示,在发动机20和电动机24之间的可用的减少比率被确定为3:1。因此,控制器11保持在转矩干预之前的电动机充电转矩,并且根据可用的减少比率3:1划分请求转矩减少的量。即,控制器11可以由发动机转矩的减少满足请求转矩减少的量的3/4且由电动机充电转矩的增加满足请求转矩减少的量的1/4。
如上所述,当在转矩干预之前电动机状态是充电状态时,保持电动机充电转矩,从而提高电动机的充电量。因此,可以有效地管理电池SOC。为了这些目的,控制器11可以被实施为由预定确定的程序操作的至少一个处理器,并且为了实行根据本公开的实施例的用于控制混合动力电动车辆的转矩干预的方法的每个步骤,该预先确定的程序可以进行编程。
例如,本文所描述的各种实施例可以在记录介质内实施,所述记录介质可以通过使用软件、硬件或其组合由计算机或类似的设备读取。根据硬件实施,本文所描述的实施例可以通过使用专用集成电路(ASIC)、数字信号处理器(DSP)、数字信号处理设备(DSPD)、可编程逻辑设备(PLD)、现场可编程门阵列(FPGA)、处理器、控制器、微控制器、微处理器和被设计用于实行任何其他功能的电动单元中的至少一个来实施。根据软件实施,可以由单独的软件模块实施实施例诸如在本实施例中所描述的过程和功能。每个软件模块可以实行在本公开中所描述的一个或多个功能和操作。软件代码可以由以适当的程序语言编写的软件应用程序来实施。
在下文中,将参考图8和图9详细描述根据本公开的实施例的用于控制混合动力电动车辆的转矩干预的方法。
图8和图9是根据本公开的实施例示出用于控制混合动力电动车辆的转矩干预的方法的流程图。
如图8和图9所示,当在步骤S101从TCU 16或TCS 32请求转矩减少时,根据本公开用于控制混合动力电动车辆的转矩干预的方法从检测用于控制转矩干预的数据开始。即,控制器11可以检测在转矩干预之前的发动机转矩EngTq、在转矩干预之前的电动机转矩MotTq、请求转矩减少的量RedTgt和电动机的充电极限ChgLmt。
当在步骤S101检测数据,在步骤S102,控制器11通过把在转矩干预之前的发动机转矩EngTq和在转矩干预之前的电动机转矩MotTq加起来计算在转矩干预之前的总需求转矩DmdTq。
之后,当在步骤S103请求转矩干预时,控制器11将在转矩干预之前的总需求转矩DmdTq与请求转矩减少的量RedTgt相比较。
当在步骤S103在转矩干预之前的总需求转矩DmdTq小于或等于请求转矩减少的量RedTgt时,在步骤S104,控制器11将在转矩干预之前的发动机转矩EngTq和在转矩干预之前的电动机转矩MotTq确定为与在转矩干预之后的发动机转矩EngTqInt和在转矩干预之后的电动机转矩MotTqInt相同。
另一方面,在步骤S103,当在转矩干预之前的总需求转矩DmdTq大于请求转矩减少的量RedTgt时,在步骤S105,控制器11确定在转矩干预之前的电动机状态是辅助状态还是充电状态。
当在步骤S105在转矩干预之前的电动机状态是辅助状态时,在步骤S106,控制器11确定由电动机辅助转矩是否满足请求转矩减少的量RedTgt。
在步骤S106,当通过从在转矩干预之前的总需求转矩DmdTq减去请求转矩减少的量RedTgt而获得的值小于或等于在转矩干预之前的电动机转矩MotTq时,控制器11确定由在转矩干预之前的电动机转矩MotTq满足请求转矩减少的量RedTgt。因此,在步骤S107,控制器11确定在转矩干预之后的发动机转矩和在转矩干预之后的电动机转矩。即,控制器11可以将在转矩干预之前的发动机转矩EngTq确定为和在转矩干预之后的发动机转矩EngTqInt相同,并且可以将在转矩干预之后的电动机转矩MotTqInt确定为通过从请求转矩减少的量RedTgt减去在转矩干预之前的发动机转矩EngTq而获得的值。
另一方面,当在步骤S106通过从在转矩干预之前的总需求转矩DmdTq减去请求转矩减少的量RedTgt获得的值大于在转矩干预之前的电动机转矩MotTq时,控制器11确定不能仅由在转矩干预之前的电动机转矩MotTq满足请求转矩减少的量RedTgt。因此,在步骤S108,控制器11首先减少在转矩干预之前的电动机转矩MotTq,并且通过以下方程式1计算额外的减少需求。
(方程式1)
RedRq=(DmdTq-RedTq)-MotTq
可以通过从在转矩干预之前的总需求转矩DmdTq减去请求转矩减少的量RedTgt获得的值减去在转矩干预之前的电动机转矩MotTq来计算额外的减少需求RedRq。
之后,在步骤S109,当在转矩干预之前的电动机状态是辅助状态时,控制器11设置发动机的可用的减少范围和电动机的可用的减少范围。
本文中,发动机和电动机的可用的减少范围意指在转矩干预之前发动机20和电动机24的可用的转矩减少的量。发动机20可以在转矩干预之前减少全部转矩,所以发动机的可用的减少范围EngCap可以设置与在转矩干预之前的发动机转矩EngTq相同(EngCap=EngTq)。
另外,电动机24提前将电动机辅助转矩减少到0转矩,并且电动机的可用的减少范围MotCap可以被设置为从0转矩到充电极限(MotCap=0-ChgLmt)。
在步骤S110,控制器11确定在转矩干预之后的发动机转矩和在转矩干预之后的电动机转矩,以按发动机的可用的减少范围EngCap和电动机的可用的减少范围MotCap的比例划分额外的减少需求RedTq。此时,可以由以下的方程式2计算在转矩干预之后的发动机转矩EngTqInt。
(方程式2)
EngTqint=EngTq-RedRq×EngCap/(EngCap+MotCap)
本文中,EngTqInt是在转矩干预之后的发动机转矩,EngTq是在转矩干预之前的发动机转矩,RedTq是额外的减少需求,EngCap是发动机的可用的减少范围,以及MotCap是电动机的可用的减少范围。
另外,可以由以下的方程式3计算在转矩干预之后的电动机转矩MotTqInt。
(方程式3)
MotqInt=0-RedRq×MotCap/(EngCap+MotCap)
之后,在步骤S114,控制器11根据确定的在转矩干预之后的发动机转矩和在转矩干预之后的电动机转矩实行转矩减少。
同时,将参考图9描述在步骤S105在转矩干预之前的电动机状态是充电状态的案例。在步骤S111,控制器11保持电动机充电转矩,并且由以下的方程式4计算额外的减少需求。
(方程式4)
RedRq=(DmdTq-RedTq)-0
本文中,可以通过从在转矩干预之前的总需求转矩DmdTq减去请求转矩减少的量RedTgt获得的值减去0来计算额外的减少需求RedRq。
在步骤S112,当在转矩干预之前的电动机状态是充电状态时,控制器11设置发动机的可用的减少范围和电动机的可用的减少范围。发动机20可以减少在转矩干预之前的全部转矩,所以发动机的可用的减少范围EngCap可以设置与在转矩干预之前的发动机转矩EngTq相同(EngCap=EngTq)。
另外,电动机24可以将转矩减少为与充电极限一样多,所以电动机的可用的减少范围可以被设置为从在转矩干预之前的充电转矩MotTq(<0)到充电极限ChgLmt(MotCap=MotTq<0-ChgLmt)。
在步骤S113,控制器11确定在转矩干预之后的发动机转矩和在转矩干预之后的电动机转矩,以按发动机的可用的减少范围EngCap和电动机的可用的减少范围MotCap的比例划分额外的减少需求RedTq。
此时,可以由上面的方程式2计算在转矩干预之后的发动机转矩EngTqInt。另外,可以由以下的方程式5计算在转矩干预之后的电动机转矩MotTqInt。
(方程式5)
MotqInt=MotTq(<0)-RedRq×MotCap/(EngCap+MotCap)
之后,在步骤S114,控制器11根据确定的在转矩干预之后的发动机转矩和在转矩干预之后的电动机转矩实行转矩减少。
如上所述,根据本公开的实施例,混合动力电动车辆首先减少在转矩干预之前的电动机辅助转矩,并且按发动机的可用的减少范围和电动机的可用的减少范围的比例划分额外的减少需求,从而防止电池SOC的耗尽。另外,当在转矩干预之前的电动机状态是充电状态时,保持电动机充电转矩,从而提高电动机的充电量。此外,发动机转矩与电动机转矩一道被减少,所以发动机噪声可以被减少,并且NVH性能可以被提高。
虽然结合目前认为是实用的实施例已经描述了本公开,但应当理解,本公开并不局限于所公开的实施例,相反,本公开旨在覆盖包括在随附权利要求书的精神和保护范围内的各种修改和等效布置。

将通过从在转矩干预之前的总需求转矩减去所述请求转矩减少的量获得的值与在转矩干预之前的所述电动机转矩相比较;
将在转矩干预之后的所述发动机转矩确定为等于在转矩干预之前的所述发动机转矩;以及
当所述请求转矩减少的量的值小于在转矩干预之前的所述电动机转矩时,将在转矩干预之后的所述电动机转矩确定为通过从所述请求转矩减少的量减去在转矩干预之前的所述发动机转矩获得的值。
11.根据权利要求10所述的方法,其中当所述请求转矩减少的量的值大于或等于在转矩干预之前的所述电动机转矩时,通过从在转矩干预之前的所述总需求转矩减去所述请求转矩减少的量和在转矩干预之前的所述电动机转矩,计算所述请求转矩减少的量。
12.根据权利要求7所述的方法,其中当在转矩干预之前所述电动机的所述状态是所述辅助状态时,所述发动机的可用的减少范围被设置为从在转矩干预之前的发动机转矩到0转矩,并且所述电动机的可用的减少范围被设置为从0转矩到所述充电极限。
13.根据权利要求7所述的方法,其中当在转矩干预之前所述电动机的所述状态是所述充电状态时,通过从在转矩干预之前的总需求转矩减去所述请求转矩减少的量,来计算所述额外的减少需求。
14.根据权利要求7所述的方法,其中当在转矩干预之前所述电动机的所述状态是所述充电状态时,所述发动机的可用的减少范围被设置为从在转矩干预之前的所述发动机转矩到0转矩,并且所述电动机的可用的减少范围被设置为从在转矩干预之前的充电转矩到所述充电极限。
