Description

具有至少一个用于控制混合动力车辆中的内燃机的电子的控 制单元的控制***
技术领域
本发明涉及一种具有至少一个用于控制混合动力车辆中的内燃机的电子的控制单元的控制***。
背景技术
已从许多年以来，混合动力车辆也已经作为批量生产车辆已知，它们包含至少一个内燃机和至少一个电动机作为驱动马达。这种混合动力车辆具有控制***，所述控制***具有至少一个电子的控制单元，所述电子的控制单元尤其是通过相应编程的功能模块执行不同的运行方法，用于选择适配于相应当前的行驶状况的运行模式。可选择的运行模式尤其是纯电动行驶(仅电动机驱动，或者说“E模式”，或者说“E行驶”)、纯内燃机驱动行驶(仅内燃机驱动)和/或混合驱动行驶(不仅电动机而且内燃机驱动)。
已知的运行方法优先考虑电池组或其他蓄电器(例如超级电容)的充电状态来选择运行模式。
发明内容
本发明的目的是，对开头提及类型的控制***在防止无意的运行模式变换的纯电动行驶稳健性方面以及在内燃机起动舒适性方面进行改进。
所述目的按本发明通过权利要求1的主题达到。本发明的有利的扩展方案包含在从属权利要求中。
按本发明的控制***具有至少一个用于控制混合动力车辆中的内燃机的电子的控制单元，该控制单元至少得到车辆速度以及得到驾驶员、安全调节***或驾驶员辅助***的行驶功率期望。控制单元构成为(尤其是编程为)，使得在低于预定的车辆速度阈值时和/或在识别到市内区域时，从纯电动行驶出发，仅在当前的行驶功率期望超过预定的上阈值时，优选在至少达到用于纯电动行驶的在车轮上的(已知的)最大可能的牵引力之后，控制单元才接通内燃机。
通过本发明，尤其是在市内区域中行驶时，纯电动行驶保持尽可能久，但是在相对高的行驶功率期望时保证足够的起动稳健性。
在本发明的一种扩展方案中，控制单元构成为，使得行驶功率期望的预定的上阈值定义为低于为逃离功能设置的与车辆速度无关的行驶功率期望阈值(尤其是加速踏板的强制降挡位置)。通过本发明的该扩展方案，在良好的起动稳健性的同时达到充足的起动舒适性。
优选控制单元也构成为，使得在高于预定的车辆速度阈值时和/或在市内区域之外时能进行动态的行驶功率期望预测，通过动态的行驶功率期望预测，已经在当前的行驶功率期望超过行驶功率期望的预定的上阈值之前和/或在超过用于纯电动行驶的在车轮上的最大可能的牵引力之前能接通内燃机。动态的行驶功率期望预测可以例如借助于当前的行驶功率期望(尤其是当前的加速踏板角度)和借助于当前的行驶功率期望的当前的梯度来预先计算出，是否因此用于纯电动行驶的在车轮上的最大可能的牵引力以相对高的概率马上要被超过。本发明的该扩展方案有助于在较高速度时进一步提高起动舒适性，在市内区域之外时尤其如此。
附图说明
在附图中描述本发明的实施例。附图如下：
图1显示用于工作运行按本发明的在混合动力车辆中的控制***的主要组件；
图2显示在已经已知的“自动电动行驶模式”中用于接通内燃机的工作运行的与特性曲线相关的视图，描述为在平坦车道上的与速度相关的车辆加速度潜能；
图3显示在已经已知的带有逃离功能的“最大电动行驶模式”中用于接通内燃机的工作运行的与特性曲线相关的视图，描述为在平坦车道上的与速度相关的车辆加速度潜能；
图4显示在新的“市内电动行驶模式”中借助于按本发明的控制***用于接通内燃机的工作运行的与特性曲线相关的视图，描述为在平坦车道上的与速度相关的车辆加速度潜能。
具体实施方式
在图1中描述所谓的在公路上运行的混合动力车辆F(例如BWM i8)，其包括电动机1和内燃机3，该电动机作为第一驱动马达例如作用在前轴VA上，该内燃机作为第二驱动马达作用在后轴HA上。第二电动机2可以附加于内燃机3地设置。另外，第二变速器4优选以可电子控制的自动变速器的形式(如由BMW批量生产车辆的现有技术已知)在输入侧与内燃机3连接。本发明也可以类似地应用于组件2、3和4的其他设置的顺序。也可能的是，电动机1设置在后轴上并且内燃机3设置在前轴上。电动机1在没有中间连接的离合器的情况下与两挡变速器7共同作用。
混合动力车辆F可以通常在具有能按需要自动地接通和断开的内燃机3的运行模式(自动电动行驶)中运行。此外，混合动力车辆F可以具有能由驾驶员操纵的选择装置(“最大电动行驶”按键)，用于手动地变换到运行模式(最大电动行驶)中，在该模式中，原则上尽可能纯电动行驶。
另外，在混合动力车辆中存在本身已知的(例如由BMW批量生产车辆已知的)电子的变速器选择装置9，通过该变速器选择装置能够由驾驶员选择通常的为自动变速器4设置的行驶位置P、R、N和D以及换挡模式“S”或“M”。
最后在图1中示意性地描述也已知的加速踏板，加速踏板的偏转、尤其是以加速踏板角度FP的形式按已知方式例如经由电位计被检测。
混合动力车辆F的驱动控制优选通过第一电子控制器5执行，通过该控制器原则上能执行用于所有存在的驱动马达的与车轮力矩相关的总驱动控制。另外例如也在控制器5中或者优选(如在此所示的那样)在机电一体化地在地点上更靠近地配设给两挡变速器7的辅助控制器8中包含用于控制变速器的功能模块GS-E。
为了识别在市内区域中的车辆运行，导航***10也可以与控制单元5连接。
控制器5和8优选通过数据总线(例如CAN总线)相互连接和按照需要交换传感器信号和控制信号。例如控制器5能够从控制器8得到车辆速度v作为信息。
控制器5具有按本发明的功能模块11，例如功能模块的形式为软件程序模块。功能模块11构成为(尤其是编程为)，使得功能模块使按本发明的控制***能工作运行。
在控制器5中或者在功能模块11中存储特性曲线和/或算法，用于转换运行模式，例如从已知的最大电动行驶模式转换到自动电动行驶模式或者相反地转换，它们在下面借助于图2～4更详细地解释。
在图2中示意性地描述原则上已知的自动电动行驶模式，在该自动电动行驶模式中，尤其是根据纯电动时在车轮上的最大可能的牵引力(描述为在平坦车道上的与速度相关的车辆加速度潜能(极限)特性曲线a/v max_e)和对于组合行驶(电动和内燃机驱动的行驶)在车轮上的最大可能的牵引力(描述为在平坦车道上的与速度相关的车辆加速度潜能(极限)特性曲线a/v max_g)，按照需要自动地接通和断开内燃机3。
在图3中示意性地描述已知的最大电动行驶模式，在该最大电动行驶模式中，按照对于纯电动行驶在车轮上的最大可能的牵引力(a/v max_e)，原则上纯电动地行驶。但是然而在逃离功能的意义中接通内燃机3，如果尤其是经由加速踏板发出强制降挡指令的话。缩写Z表示内燃机3的接通。
用图4更具体地解释与现有技术不同的按本发明的控制***及其工作运行方式。在图4中规定在此大约65km/h的车辆速度阈值。该阈值是示例性地选择的，因为该阈值反映在市内区域(城市)中的通常最大的行驶速度v。按本发明的新的运行模式因此也由申请人称为“市内电动行驶”。按本发明，在低于在此大约65km/h的车辆速度阈值时和/或在通过导航***10识别到市内区域时，从纯电动行驶出发，仅在当前的行驶功率期望FP超过在此大约90％的预定的上阈值时，优选在至少达到用于纯电动行驶的加速度-速度(极限)特性曲线a/v max_e之后，控制单元5或功能模块11才接通内燃机3。
在此大约90％的行驶功率期望FP的上阈值优选定义为低于按图3为逃离功能规定的与车辆速度无关的行驶功率期望阈值(在此为强制降挡位置)。
按图4，控制单元5构成为，使得在大于在此大约65km/h的预定的车辆速度阈值时，进行动态的行驶功率期望预测P_dyn，通过动态的行驶功率期望预测，内燃机3已经在行驶功率期望FP超过在此90％的预定的上阈值之前和/或在超过对于纯电动行驶在车轮上的最大可能的牵引力a/v max_e之前能被接通。动态的行驶功率期望预测P_dyn例如借助当前的行驶功率期望FP及其当前的梯度计算出预测的行驶功率期望FP’。控制单元5检验，是否因此使得用于纯电动行驶的在车轮上的最大可能的牵引力a/v max_e以相对高的概率马上要被超过。如果是这种情况，那么在达到纯电动最大可能的牵引力a/v max_e之前，接通内燃机3。
