Description

用于车辆的变速控制装置
技术领域
根据本发明的实施例涉及一种用于车辆的变速控制装置。
背景技术
已知一种用于混合动力车辆的控制装置，其使用电机转矩来弥补在升挡变速期间传送到驱动轮的转矩的瞬时中断，从而防止由于转矩遗漏而引起的驾驶员的不适感，加强加速感。
当伴随着升挡变速，离合器的断开使从发动机向驱动轮的转矩传送暂时停止时，该用于混合动力车辆的控制装置使电机运转，并将电机转矩传送到驱动轮以弥补转矩。该用于混合动力车辆的控制装置使通过下一级变速齿轮传送的发动机转矩与由电机补偿的转矩基本上相互匹配，以防止转矩遗漏(参见专利文献1(日本专利公开No.2013-56618))。
发明内容
近年来，已经提出一种配备有级变速器的混合动力车辆作为混合动力车辆的一种形式。在配备有级变速器的混合动力车辆中，在变速时离合器切断从发动机到驱动轮的动力传送路径，因此发生转矩遗漏。
因此，该传统混合动力车辆的控制装置在变速齿轮切换到下一级的瞬间通过电机转矩进行补偿。
然而，配备有级变速器的混合动力车辆一方面进行所谓的EV行驶，即利用电机的动力转矩行驶，以及进行所谓的电机辅助，即，用电机的动力转矩补充发动机转矩；另一方面在减速时使用输入到电机的再生转矩来发电，即所谓的再生发电，以及由电机使用发动机转矩来发电。
车辆行驶期间进行电机辅助还是使用发动机转矩来发电，换句话说，电机输出动力转矩还是输出再生转矩取决于加速器开度和可充电电池的充电状态，因此，在不是固定的。
当电机进行再生发电或使用发动机转矩进行发电时，即，电机输出再生转矩时，在离合器断开以改变变速器的速度的瞬间，电机被驱动以使车辆减速。当电机的动力转矩增加以弥补(补充，补偿)发动机转矩时，总转矩，即发动机转矩+电机转矩，突然减小。总转矩的突然减小给驾驶员带来不适感。
为了解决上述问题，本发明的目的是提供一种用于车辆的变速控制装置，其减小变速开始时转矩的显著变化，以抑制驾驶员的不适感。
为了实现上述目的，本发明的一个方面提供一种用于车辆的变速控制装置，包括：电机，其使用驱动轮的再生转矩或发动机产生的发动机转矩来发电，并且使用可充电电池的电力来产生用于所述驱动轮的动力转矩；变速器，其将所述发动机转矩传送到所述驱动轮；离合器，其在所述发动机和所述变速器之间传送和切断所述发动机转矩；和控制器，其控制所述电机的所述动力转矩、所述离合器的断开和接合以及所述变速器的变速。当所述控制器在所述电机进行发电期间使所述变速器改变速度时，所述控制器减小所述电机的转矩，开始所述离合器的断开，然后开始所述变速器的变速。
优选地，所述控制器基于车速和加速器开度之间的关系允许所述变速器的变速，并且在减小所述电机的所述转矩的过程中，对应于所述电机的所述转矩的减小量，减小所述发动机转矩。
优选地，所述控制器将所述电机的所述转矩基本上减小到零值，然后基于车速和加速器开度之间的关系来增加所述电机的所述动力转矩。
优选地，所述控制器在所述离合器断开期间用所述电机的所述动力转矩驱动所述驱动轮。
优选地，所述控制器在所述变速器的变速完成之后，减小所述电机的所述动力转矩，并且对应于所述动力转矩的减小量，增加所述发动机转矩。
根据本发明，所述用于车辆的变速控制装置减小了变速开始时转矩的显著变化，以抑制驾驶员的不适感。

具体实施方式
将参照图1至图6描述根据本发明的用于车辆的变速控制装置的一实施例。
图1是根据本发明该实施例的用于车辆的变速控制装置的系统配置图。
如图1中所示，根据该实施例的变速控制装置1安装在车辆2中。
车辆2是配备有内燃发动机5和电机7作为动力源的混合动力车辆(HEV，HybridElectric Vehicle)。
发动机转矩Te通过离合器9和变速器11从发动机5传送到驱动轮12。电机7的动力转矩Tp通过变速器11传送到驱动轮12。驱动轮12的再生转矩Tr通过变速器11传送到电机7。
离合器9在发动机5和变速器11之间传送和切断发动机转矩Te。
当离合器9接合时，发动机5和变速器11通过离合器9连接。在这种情况下，发动机转矩Te通过变速器11的变速齿轮中的任一个传送到驱动轮12。
当离合器9断开时，发动机5和变速器11之间的连接被取消。在这种情况下，发动机转矩Te不传送到驱动轮12，但是动力转矩Tp传送到驱动轮12，或者再生转矩Tr传送到电机7。离合器9的接合和断开由致动器(未示出)进行。
变速器11是以手动变速器为基础的。变速器11的速度由致动器(未示出)改变。当改变变速器11的速度时，使离合器9断开。结果，从发动机5传送到变速器11的发动机转矩Te被暂时切断。
电机7使用驱动轮12的再生转矩Tr进行再生发电，并且使用可充电电池15的电力来产生用于驱动轮12的动力转矩Tp。此外，电机7也使用发动机转矩Te来发电。
可充电电池15例如是锂离子电池。可充电电池15通过逆变器16连接到电机7。逆变器16将可充电电池15的直流(DC)电转换成交流(AC)电以使电机7工作，而当电机7发电时，逆变器16将所产生的交流电转换为直流电，以对可充电电池15充电。
车辆2根据发动机5和电机7的操作状态以及离合器9的接合或断开状态切换行驶模式。行驶模式包括电机行驶模式、发动机行驶模式以及电机和发动机行驶模式。在电机行驶模式中，车辆2使离合器9断开，使发动机5停止以停止发动机转矩Te的输出，使电机7工作以产生动力转矩Tp，并且通过变速器11将电机7的动力转矩Tp传送到驱动轮12以行驶。在发动机行驶模式中，车辆2使电机7停止以停止动力转矩Tp的输出，使离合器9接合，使发动机5工作以产生发动机转矩Te，并且通过离合器9和变速器11将发动机转矩Te传送到驱动轮12以行驶。在电机和发动机行驶模式中，车辆2使离合器9接合，使发动机5工作，使电机7工作，并且将发动机转矩Te和电机7的动力转矩Tp传送到驱动轮12以行驶。电机7还用作交流发电机，并且在减速时使用驱动轮12的再生转矩Tr进行再生发电。
根据本实施例的变速控制装置1配备有：电机7，其使用驱动轮12的再生转矩Tr或发动机5的发动机转矩Te来发电，并且使用可充电电池15的电力来产生用于驱动轮12的动力转矩Tp；变速器11，其将发动机5产生的发动机转矩Te传送到驱动轮12；离合器9，其在发动机5和变速器11之间传送和切断发动机转矩Te；和控制器18，其控制电机7的动力转矩Tp、离合器9的断开和接合以及变速器11的变速。
变速控制装置1还配备有检测车辆2的车速的车速检测器21和检测由驾驶员操作的加速器(未示出)的操作量的加速器开度检测器22。
控制器18是所谓的发动机控制单元(ECU)。
控制器18通过控制燃料喷射量、喷射正时和发动机5的其他特性来操作发动机5。此外，控制器18驱动变速器11的致动器以进行变速。控制器18与变速控制相关联地驱动离合器9的致动器以进行离合器9的断开和接合。即，变速器11用作有级自动变速器。
控制器18通过逆变器16控制可充电电池15的充电和放电，并且将可充电电池15的充电状态(SOC)控制在预定范围内。
也就是说，控制器18通过将发动机5的操作、电机7的操作、变速器11的变速以及离合器9的断开和接合相互联系来进行行驶模式的切换控制。
为了进行各种控制，各种传感器的检测信号，如车速检测器21的检测信号、加速器开度检测器22的检测信号和发动机转速检测器(未示出)的检测信号，被输入到控制器18。电机7的动力转矩Tp和再生转矩Tr的测量值被输入到控制器18。由连接到可充电电池15的电流检测器(未示出)检测到的充电和放电电流值、由连接到可充电电池15的电压检测器(未示出)检测到的电压值和由连接到可充电电池15的温度检测器(未示出)检测到的可充电电池温度被输入到控制器18。控制器18基于该充电和放电电流值、该电压值和该可充电电池温度来计算可充电电池15的SOC。
当电机7进行再生发电或使用发动机转矩Te进行发电时，即，当电机7输出再生转矩Tr时，在离合器9断开以改变变速器11的速度的瞬间，电机7被驱动而使车辆2减速。当在这种情况下增加电机7的动力转矩Tp以弥补(补充，补偿)发动机转矩Te时，总转矩(发动机转矩Te+电机转矩Tp，Tr)突然减小，并最终给驾驶员带来不适感。
图2是传统变速控制的时序图。
如图2中所示，在该传统变速控制中，在电机7进行再生发电期间，即在电机7输出再生转矩Tr(负转矩)期间，离合器9断开(图2中的时刻A)时，总转矩(发动机转矩Te+电机转矩Tp，Tr)减小并且转变到负值。这种现象是由于离合器9断开时的速度快于电机7的动力转矩Tp开始时的速度而发生的。
当离合器9断开时，总转矩基本上等于电机转矩Tp和Tr。也就是说，在该传统变速控制中电机7输出再生转矩Tr的状态下，当离合器9断开(图2中的虚线区域)时，总转矩突然减小，并且车辆出现拖曳感或不舒服的变速冲击，最终给驾驶员带来不适感。当电机7使用发动机转矩Te进行发电时，也会发生该现象。
因此，控制器18进行可以减小变速开始时转矩的显著变化的变速控制。将详细描述根据本实施例的变速控制。
图3是根据本发明该实施例的用于车辆的变速控制装置的变速控制流程图。
图4是根据本发明该实施例的用于车辆的变速控制装置的变速控制时序图。
图5是根据本发明该实施例的用于车辆的变速控制装置的变速控制中的变速映射的例子。
图6是根据本发明该实施例的用于车辆的变速控制装置的变速控制中的转矩映射的例子。
如图3和图4中所示，当电机7进行发电期间，根据本实施例的用于车辆的变速控制装置1的控制器18改变变速器11的速度时，控制器18减小电机7的再生转矩Tr，开始离合器9的断开，然后开始变速器11的变速。
此外，控制器18根据车速和加速器开度之间的关系允许变速器11的变速，并且在减小电机7的再生转矩Tr的过程中，对应于再生转矩Tr的减小量，减小发动机转矩Te。
此外，控制器18将再生转矩Tr基本上减小到零值，然后根据车速和加速器开度之间的关系增加电机7的动力转矩Tp。
此外，控制器18在离合器9断开期间用电机7的动力转矩Tp驱动驱动轮12。
此外，控制器18在变速器11的变速完成之后，减小电机7的动力转矩Tp，并且对应于动力转矩Tp的减小量，增加发动机转矩Te。
具体地，控制器18接收车速检测器21的检测信号和加速器开度检测器22的检测信号，即，最终得到车速和加速器开度(步骤S1)。
接下来，控制器18将该车速和该加速器开度与变速映射(图5)进行比对，并且确定是否允许变速器11的变速(步骤S2)。当控制器18允许变速器11的变速时，控制器18开始变速，并执行步骤S3和后续步骤。当控制器18不允许变速器11的变速时(图4中的时刻A)，控制器18在保持变速器11的变速位置的同时重复变速控制。
图5是变速映射的例子。该变速映射是预先根据加速器开度和车速之间的关系设定的。例如，当车辆2以10％的加速器开度加速时，当车速达到10km/小时时，允许从第一档向第二档变速。
当控制器18允许变速器11的变速时(步骤S2“是”)，控制器18停止电机7再生发电(步骤S3)。电机7的再生转矩Tr减小，并且最终达到零值，终止电机7的再生发电。控制器18在减小电机7的再生转矩Tr的过程中(图4中从时刻A到时刻B)，对应于再生转矩Tr的减少量，减小发动机转矩Te。
随后，控制器18使离合器9断开，以进行变速器11的变速(步骤S4，图4中的时刻B)。
在进行变速器11的变速的过程中，控制器18将电机7的再生转矩Tr基本上减小到零值，然后根据车速和加速器开度之间的关系，例如，图6中的转矩映射，增大动力转矩Tp。
图6是转矩映射的例子。该转矩映射是预先根据加速器开度和车速之间的关系设定的。控制器18控制发动机5和电机7的动作，使得例如当加速器开度为10％并且车速为0km/小时时，总转矩(发动机转矩Te+电机转矩Tp，Tr)达到300牛顿米。
此外，在离合器9断开期间，即，在进行变速器11的变速期间，控制器18利用电机7的动力转矩Tp驱动驱动轮12(图4中从时刻C到时刻D)。从而使变速器11能够平滑地进行变速。
此外，控制器18在变速器的变速11完成之后，减小电机7的动力转矩Tp，并且对应于动力转矩Tp的减小量，增加发动机转矩Te(图4中，时刻D之后)。由此，可以抑制总转矩(发动机转矩Te+电机转矩Tp，Tr)的变化。
根据本实施例的变速控制装置1在减小电机7的再生转矩Tr之后(图4中，从时刻A到时刻B)使离合器9断开。结果，变速控制装置1消除了变速时的拖曳感或不舒服的变速冲击，并且能够防止驾驶员的不适感。注意，在使离合器9断开之前(图4中的时刻B)，不必将再生转矩Tr减小到零值。也就是说，在离合器9断开之前，即使再生力矩Tr稍微减小，也可以减少拖曳感或不舒服的变速冲击，并且可以降低驾驶员的不适感。
当根据本实施例的变速控制装置1在电机7进行再生发电期间改变变速器11的速度时，变速控制装置1减小电机7的再生转矩Tr，开始离合器9的断开，然后开始变速器11的变速。结果，变速控制装置1减少了变速时总转矩的变化，并且可以最终抑制驾驶员的不适感。
根据本实施例的变速控制装置1在减小电机7的再生转矩Tr的过程中，对应于再生转矩Tr的减小量，减小发动机转矩Te。结果，变速控制装置1可靠地减少了变速时总转矩的变化，并且最终能够进一步抑制驾驶员的不适感。
根据本实施例的变速控制装置1将电机7的再生转矩Tr基本上减小到零值后，根据车速和加速器开度之间的关系增加电机7的动力转矩Tp。结果，变速控制装置1抑制了变速时的不适感，并且能够实现驾驶者对加速器操作之后的加速。
根据本实施例的变速控制装置1在离合器9断开期间用电机7的动力转矩Tp驱动驱动轮12。结果，变速控制装置1能够进行变速器11的平滑变速。
根据本实施例的变速控制装置1在变速器11的变速完成之后，减小电机7的动力转矩Tp，并且对应于动力转矩Tp的减小量，增加发动机转矩Te。结果，变速控制装置1能够抑制变速后总转矩的变化。
当电机7使用发动机转矩Te进行发电时，变速控制装置1也类似地展现出这些效果。
因此，基于根据本发明的变速控制装置1，能够减少变速开始时转矩的显著变化，以能够抑制驾驶员的不适感。
