Description

车辆及车辆控制方法
技术领域
本发明涉及利用可间歇运转的内燃机驱动的车辆及此车辆的对应控制方法。
背景技术
在未完成用于调整发动机的怠速至目标怠速的节气门开度的回馈控制的控制量的学习的情况下，一种应用于设有该发动机的车辆的提案是禁止停止发动机直到完成该学习(参见，例如，  日本专利特开平No.H11-107834)。此提案不停止车辆的发动机直到完成用于调整怠速的控制量的学习。此提案可应用于对用于调整怠速的控制量的学习机会少的混合动力车。在此应用中，设定适当的学习值和充分反映用于节气门开度的回馈控制的学习值实现发动机的良好怠速运转。
发明内容
此现有车辆的提案无条件地禁止停止发动机，且继续该发动机的运转直到完成用于调整怠速的控制量的学习。在一些情况中，发动机的此继续运转与驾驶员的设想(估计，假想)相反，且使该驾驶员感到某部件发生故障。
因此，本发明的车辆及车辆控制方法的目的是确保用于内燃机的怠速运转的控制量的学习机会而不使驾驶员感到某部件发生故障。
为至少部分实现以上和其它相关目的，此车辆和车辆控制方法具有下述构造。
本发明旨在一种利用可间歇运转的内燃机驱动的车辆。该车辆包括：怠速控制量学习装置，该怠速控制量学习装置学习用于内燃机的怠速运转的控制量；以及间歇运转禁止装置，该间歇运转禁止装置在怠速控制量学习装置未完成控制量的学习的情况下，基于存在或不存在驾驶员的预定运转来禁止内燃机的间歇运转直到完成该学习。
在未完成用于内燃机的怠速运转的控制量的学习的情况下，本发明的车辆基于驾驶员的预定操作来禁止内燃机的间歇运转直到完成该学习。此布置有效地避免内燃机与驾驶员的设想相反地继续运转，同时禁止该内燃机的间歇运转。此布置理想地确保内燃机的运转而不使驾驶员感到某部件发生故障。驾驶员的预定操作是例如使该驾驶员设想内燃机的间歇运转的操作。
在本发明车辆的一种优选应用中，间歇运转禁止装置响应于驾驶员的换档操作禁止内燃机的间歇运转。此应用充分禁止内燃机的间歇运转。在此应用的一例中，间歇运转禁止装置响应于作为驾驶员的换档至驻车档位的操作而允许内燃机的间歇运转，并且响应于作为该驾驶员的换档至除该驻车档位以外的可行驶档位而禁止该内燃机的间歇运转。
在本发明车辆的另一优选应用中，间歇运转禁止装置响应于驾驶员的驻车制动的操作而禁止内燃机的间歇运转。此应用充分禁止内燃机的间歇运转。
在本发明车辆的又一优选应用中，车辆还包括用于驱动该车辆的电动机。本发明车辆还包括：三轴式动力输入输出机构，该三轴式动力输入输出机构与三根轴连接，并基于从该三根轴中任何两根轴输入的动力和向该三根轴中任何两根轴输出的动力来从剩余一根轴输入动力和向该剩余一根轴输出动力，其中，该三根轴是内燃机的输出轴、与车轴连接的驱动轴和第三轴；以及发电机，该发电机从第三轴输入动力和向第三轴输出动力。
本发明还旨在一种车辆控制方法，该车辆控制方法控制利用可间歇运转的内燃机驱动的车辆。该车辆控制方法包括以下步骤：学习用于内燃机的怠速运转的控制量；以及在步骤(a)中未完成该控制量的学习的情况下，基于存在或不存在驾驶员的预定操作来禁止内燃机的间歇运转直到完成该学习。
在未完成用于内燃机的怠速运转的控制量的学习的情况下，本发明的控制方法基于驾驶员的预定操作来禁止内燃机的间歇运转直到完成该学习。此布置有效地避免内燃机与驾驶员的设想相反地继续运转，同时禁止该内燃机的间歇运转。此布置理想地确保用于内燃机的怠速运转的控制量的学习机会而不使驾驶员感到某部件发生故障。
在本发明控制方法的一种优选应用中，步骤(b)响应于作为驾驶员的预定操作的该驾驶员换档至驻车档位的操作而允许内燃机的间歇运转，并且响应于作为该驾驶员的预定操作的该驾驶员换档至除该驻车档位以外的可行驶档位而禁止该内燃机的间歇运转。
附图说明
图1示意性示出在本发明一种实施例中的车辆的构造；以及
图2是示出利用安装在本发明车辆上的混合动力电子控制单元执行的间歇运转禁止控制程序的流程图。
具体实施方式
以下参照附图说明作为一种优选实施例的本发明实施方式。图1示意性示出在本发明一种实施例中的车辆20的构造。如图1所示，此实施例的车辆20包括发动机22、用于运转和控制该发动机22的发动机电子控制单元24(以下称为发动机ECU24)，以及包括与该发动机22的曲轴26或输出轴连接的行星架和经由差速齿轮31与驱动轮32a和32b连接的驱动轴34的行星齿轮单元30。车辆20还包括与行星齿轮单元30的中心齿轮连接且具有发电能力的原动机(电机)MG1、与驱动轴34连接且具有发电能力的原动机MG2、经由逆变器42和44向原动机MG1和MG2传递电力和从该原动机MG1和MG2传递电力的电池46、用于运转和控制原动机MG1和MG2的原动机电子控制单元48(以下称为原动机ECU48)，以及用于控制整个车辆20的运转的混合动力电子控制单元50。
发动机ECU24从用于测量和检测发动机22的运转状态的各种传感器接收各种信号，且执行燃料喷射控制、点火控制和进气量调节控制。当在起动车辆20的过程中起动发动机22时，车辆ECU24学习用于当该发动机22内的冷却水的温度上升至预定温度或以上时调整怠速至目标怠速所需的控制量(例如，节气门开度)。发动机ECU存储所学到的控制量，且随后利用此所学到的控制量控制发动机22的怠速运转。发动机ECU24还存储与用于调整怠速的控制量的学习状态即完成或未完成该控制量的学习有关的信息。
原动机ECU48从用于测量和检测原动机MG1和MG2的运转状态的各种传感器接收各种信号，且对包括在各个逆变器42和44内的开关件执行开关控制。
混合动力电子控制单元50被构造成一种包括CPU52、存储处理程序的ROM54、暂时存储数据的RAM56、输入输出端口(未示出)和通信端口(未示出)的微处理器。混合动力电子控制单元50经由其输入端口接收来自点火开关60的点火信号、来自档位传感器62的换档杆61的档位SP或当前设定位置、来自加速器踏板位置传感器64的加速器踏板63的加速器开度Acc或驾驶员的下压量、来自制动器踏板位置传感器66的制动器踏板65的制动器踏板位置BP或驾驶员的下压量，以及来自车速传感器68的车速V。混合动力电子控制单元50经由其通信端口建立与发动机ECU24和原动机ECU48的通信，且从该发动机ECU24和原动机ECU48发送各种控制信号和向该发动机ECU24和原动机ECU48发送各种控制信号。
具有以上构造的此实施例的车辆20基于给定的车速V和给定的加速器开度Acc(等于驾驶员下压加速器踏板63的量)设定将输出给驱动轴34的要求转矩，并驱动和控制发动机22和原动机MG1和MG2以确保输出与此预设的要求转矩相等的要求动力。发动机22和原动机MG1和MG2有多种运转控制模式。转矩变换运转模式下，在发动机22被驱动和控制以输出与要求动力对应的规定水平动力的同时，原动机MG1和MG2被驱动和控制以能够利用行星齿轮单元30和该原动机MG1和MG2对发动机22的所有输出动力进行转矩变换以输出给驱动轴34。在充放电运转模式下，发动机22被驱动和控制以输出与要求动力和用于给电池46充电或从该电池46释放的电力的和对应的规定水平动力。原动机MG1和MG2被驱动和控制以能够利用行星齿轮单元30和该原动机MG1和MG2对与给电池充放电的要求电力相等的发动机22的输出动力的全部或部分进行转矩变换并输出给驱动轴34。在原动机运转模式下，原动机MG2被驱动和控制以能够输出与要求动力对应的规定水平动力给驱动轴34，同时发动机22停止。当电池46的充放电电力为0时，转矩变换运转模式等同于充放电运转模式。即，转矩变换运转模式被看作是充放电运转模式的一种状态。因此，此实施例的车辆20通过在原动机运转模式与充放电运转模式之间的运转控制的切换来驱动。
在以充放电运转模式动作的此实施例的车辆20中，当电池46的剩余电荷或充电状态SOC进入预设管理范围且对应于驾驶员下压加速器踏板63的量设定的车辆要求动力减小至预设第一参考水平例如2或3kW、5kW、7kW或10kW以下时，满足发动机22的自动停止条件。当满足这些发动机自动停止条件时，车辆20自动停止该发动机22并切换运转控制至原动机运转模式。在以原动机运转模式动作的此实施例的车辆20中，当对应于驾驶员下压加速器踏板63的量设定的车辆要求动力增大至比预设第一参考水平高的预设第二参考水平例如4或5kW、8kW、10kW或15kW或以上时，或者当电池46的充电状态SOC低于预设管理范围时，满足发动机22的自动起动条件。当满足这些发动机自动起动条件时，车辆20由停止自动地重新起动发动机22并切换运转控制至充放电运转模式。
本说明关于禁止发动机22的自动停止(间歇运转)而不论是否满足以上发动机自动停止条件。图2是示出利用混合动力电子控制单元50执行的间歇运转禁止控制程序的流程图。以预设的时间间隔重复执行此间歇运转禁止控制程序。
在图2的间歇运转禁止控制程序中，混合动力电子控制单元50的CPU52首先输入控制所需的各种数据，例如，来自档位传感器62的档位SP和用于调整发动机22的怠速的控制量的学习状态(步骤S100)。利用例如一种标识表示用于调整发动机22的怠速的控制量的学习状态，该标识被设定为代表完成学习的1以及被重设为代表未完成学习的0。控制量的学习状态经由通信从发动机ECU24接收。
在输入数据后，CPU52识别完成或未完成用于调整怠速的控制量的学习(步骤S110)。响应于在步骤S110完成用于调整怠速的控制量的学习，CPU52允许发动机22间歇运转(步骤S120)且退出此间歇运转禁止控制程序。间歇运转的允许在满足以上给出的发动机自动停止条件时能使车辆20自动地停止发动机22并以原动机运转模式动作，同时在满足以上给出的发动机自动起动条件时能自动地重新起动该发动机22并以充放电运转模式动作。
另一方面，响应于在步骤S110未完成用于调整怠速的控制量的学习，CPU52识别所输出的档位SP(步骤S130)。当判定所识别的档位SP为不可行驶档位例如驻车(P)档位时，CPU52允许发动机22的间歇运转(步骤S120)。另一方面，当判定所识别的档位SP为可行驶档位例如行驶(D)档位时，CPU52禁止发动机22的间歇运动(步骤S140)且退出此间歇运转禁止控制程序。间歇运转的禁止不允许车辆20自动停止发动机22而不论是否满足发动机自动停止条件。若未完成用于调整怠速的控制量的学习，在档位SP被设定为D档位的情况下禁止发动机22的间歇运转。此发动机22的间歇运转的禁止确保用于调整怠速的控制量的学习机会且在更早的时期完成学习以使发动机22的怠速运转稳定。另一方面，若未完成用于调整怠速的控制量的学习，在档位SP被设定为P档位的情况下允许发动机22的间歇运转。驾驶员一般设想在档位SP被设定为P档位时停止发动机22。此发动机22的间歇运转的允许避免发动机22与驾驶员的设想相反地继续运转，且由此防止该驾驶员感到某部件发生故障。
如上所述，若未完成用于调整怠速的控制量的学习，换档杆61被设定在D档位的此实施例的车辆20禁止发动机22的间歇运转直到完成该用于调整怠速的控制量的学习。另一方面，换档杆61被设定在P档位的车辆20允许发动机22的间歇运转。于是，此实施例的车辆20有效地避免发动机22与驾驶员的设想相反地继续运转，同时禁止该发动机22的间歇运转直到完成用于调整怠速的控制量的学习。这种布置确保用于调整怠速的控制量的学习机会而不使驾驶员感到某部件发生故障。
若未完成用于调整发动机22的怠速的控制量的学习，此实施例的车辆20基于档位SP禁止该发动机22的间歇运转。然而，此实施例的禁止控制完全不是限制性的。可响应于驾驶员希望发动机22间歇运转的任何其它操作来确定该发动机22的间歇运转的禁止。例如，可响应于驾驶员的驻车制动操作、该驾驶员的开关车辆20门的操作、或者此驾驶员的操作组合来禁止发动机22间歇运转。在基于驻车制动的激活或失活来禁止发动机22的间歇运转的变形结构中，若未完成用于调整该发动机22的怠速的控制量的学习，间歇运转禁止控制响应于驾驶员开启停止制动的操作允许该发动机22的间歇运转，同时响应于驾驶员的关闭驻车制动的操作禁止该发动机22的间歇运转。
此实施例有关本发明应用于设有发动机22、行星齿轮单元30和原动机MG1和MG2的车辆20。然而，本发明的技术不限于此构造的车辆20，也可应用于具有作为驱动源的发动机和原动机的其它构造的混合动力车，以及仅具有作为驱动源的发动机的传统机动车辆。应用本发明的车辆要求具有当满足发动机自动停止条件时自动停止且当满足发动机自动起动条件时自动重起的可间歇运转发动机。
上述实施例在所有方面都应被认为是示意性而非限制性的。存在许多变形、变化和变更而不脱离本发明主要特征的范围或精神。在与权利要求书等同的意思和范围内的所有变化都试图被包含在内。
