Description

方向盘预调节
技术领域
本发明涉及车辆内部，并且更具体地涉及车辆中的方向盘的加热和冷却。
背景技术
正在开发许多将作为电池电动车辆或插电式混合动力电动车辆被供电的机动车辆。对于这些车辆，要么没有内燃发动机，在这种情况下，没有发动机驱动的交流发电机，要么希望避免起动发动机来驱动交流发电机。因此，乘客舱或乘客舱中的部件的加热和冷却使用来自用于推进车辆的电池的电力。但是为此目的而使用推进电池会不利地影响车辆的行驶续航里程。
许多机动车辆还包括舒适特征件，诸如加热和冷却后的方向盘。然而，如上文所论述，对于电动化车辆，这种特征件可能会消耗推进电池的电力。一些人提出通过激活方向盘加热器或冷却器来对方向盘进行预调节，但这仅适用于方向盘总成中内置有加热/冷却件的车辆。其他人提出了通过远程控制预先对乘客舱进行空气调节，所述远程控制可以包括通过红外传感器检测方向盘的表面温度、从方向盘附近的HVAC风道出口调整HVAC通风件，并且从出口吹出空气以在驾驶员进入车辆之前降低方向盘的温度。这可以用于方向盘不具有其自己的加热/冷却元件的车辆中。然而，这些系统不能确保以最小的电力使用来完成对方向盘的调节以实现期望的温度。
发明内容
一个实施例设想了一种加热/冷却车辆的内部的方法，所述方法包括：接收加热/冷却请求；自动地将来自HVAC风道的加热/冷却后的空气通过邻近方向盘的通风件引导到乘客舱中；以及自动地来回旋转所述方向盘以改变所述加热/冷却后的空气被吹到所述方向盘上的位置。
一个实施例设想了一种加热/冷却车辆的内部的方法，所述方法包括：接收加热/冷却请求；自动地将来自HVAC风道的加热/冷却后的空气通过邻近方向盘的通风件引导到乘客舱中；利用红外相机获取所述方向盘的图像；以及基于所述图像自动地来回旋转所述方向盘以改变所述加热/冷却后的空气被吹到所述方向盘上的位置。
实施例的优点是方向盘将在出行之前被加热/冷却，同时使用来自车辆车载电池的最小电力。即使对于方向盘没有嵌入式加热和冷却部件的车辆，也能提供这种加热/冷却。
附图说明
图1是车辆的乘客舱的一部分的示意性透视图。
具体实施方式
图1示出了车辆20的乘客舱22的一部分。车辆20可以是例如电池电动车辆或插电式混合动力电动车辆。因此，车辆20可以连接到电池充电器23，如本领域中已知的。
在座椅26前面并且邻近具有换挡器30的中央控制台28的方向盘24可以位于乘客舱22中。方向盘24可以安装在转向柱32上、邻近仪表板34并且在加速踏板36和制动踏板38上方。仪表板34可以包括各种量表40和开关42。这些元件在本领域中是公知的。
仪表板34还可以包括位于方向盘24的左手侧和右手侧上的暖通空调(HVAC)风道44。风道44中的每一个包括多组通风件46，所述通风件允许进行调整以上下和左右地引导来自每个风道的空气。
通风件致动器48控制通风件46的移动，从而允许从控制器50自动调整气流方向。控制器50可以由如本领域中已知的电子硬件和软件的各种组合构成，并且可以通过有线或无线通信与通风器致动器48通信。通风件致动器48可以包括马达和齿轮装置以影响通风件46的移动。
一个或多个车厢温度传感器52可以位于乘客舱22中，例如位于仪表板34中，并且与控制器50通信。一个或多个车厢温度传感器52可以用于检测乘客舱22的内部的温度。
红外相机54可以位于允许相机54检测方向盘24的各个部分(特别是在车辆操作期间驾驶员的手可能位于的上部部分56)的温度的位置。该安装位置可以是任何可行的地方，诸如仪表板34、中央控制台28、后视镜或车辆车顶内衬。
除了方向盘24和转向柱32之外，转向总成58还可以包括影响转向柱32的上下倾斜的柱倾斜致动器60、影响转向柱32的前后伸缩的柱伸缩致动器62以及影响方向盘24的顺时针和逆时针旋转的转向旋转致动器64。致动器60、62、64全部可以与控制器50通信，并且各自可以包括马达和齿轮装置以影响转向柱32和方向盘24的移动。
车辆20可以包括远程信息处理系统66，所述远程信息处理系统与控制器50通信并且还与远程位置68无线地通信，这可以包括通过互联网或蜂窝通信网络进行的通信，如本领域中已知的。
现在将讨论方向盘24的冷却/加热。如本文所使用的术语“加热/冷却”或“冷却/加热”意指基于乘客舱和/或方向盘的温度进行的加热或冷却。例如，在寒冷的冬日，因为乘客舱和方向盘将是冷的，所以请求将是针对加热的。检测车辆中是需要加热还是冷却的能力在本领域中是已知的，因为车辆中的许多当前自动控制的HVAC系统提供了这种功能。
可以设定预定的行程开始时间，可以预先在车辆20中设定，也可以通过远程装置70(例如手机或其他互联网连接的装置)设定；或者可以采用远程装置来指示行程时间将很快开始，例如在十五至二十分钟内开始。该提前的行程时间通知允许电动车辆或插电式混合动力电动车辆在车辆20据推测仍连接到电池充电器23时开始冷却/加热过程。因此，可以采用来自电池充电器23的电力，而不是开始消耗车辆的车载电池。
在行程开始时间之前的预定时间(这可取决于乘客舱22和/或环境温度有多热或多冷)，激活空调/加热(视情况而定)。这种空调/加热可以用于冷却/加热方向盘24的特定目的，但是在具体地寻址方向盘24之前可以首先用于冷却/加热乘客舱22。在后一种情况下，冷却/加热经由HVAC风道44通过通风件46吹入乘客舱22，直到达到期望的乘客舱温度。期望的温度可以由请求预调节的人预设。
大约在达到乘客舱22中的期望温度时(这可以是快要达到期望温度时)，控制器50自动地控制通风器致动器48以将来自HVAC风道44的空气引向方向盘24。如果需要，这个方向可以朝向方向盘24的上部部分56。
当冷却/加热后的空气被引向方向盘24时，红外相机54可以获取方向盘24的图像。根据该图像，控制器50确定方向盘24的哪些部分是最冷/最热的，并且采用转向旋转致动器64来旋转方向盘24，以确保冷却/加热后的空气被最有效地引导到这些最冷/最热的部分上。方向盘24可以顺时针和逆时针旋转，以确保完成方向盘24的所有期望的冷却/加热。红外相机54可以在该过程期间获取多个图像，以便在进行方向盘冷却/加热过程时允许控制器50调整到方向盘24上的最近冷点/热点。替代地或另外地，可以通过使用计算机辅助设计(CAD)和计算机辅助工程(CAE)来确定方向盘24和通风件46的预定最佳定位，在这种情况下，通风件46和方向盘24可以在启动方向盘24冷却/加热过程时预先定位到优选的冷却/加热位置。
另外，如果认为方向盘24的旋转不足以确保期望的冷却/加热，则控制器50可以采用柱倾斜致动器60和/或柱伸缩致动器62以便将方向盘24上的冷点/热点与从通风件46流动的空气更好地对准。这可以在冷却/加热过程期间根据需要基于最新的红外相机图像在任何时间发生。
因此，当人到达车辆20并将其与电池充电器23断开连接时，乘客舱22、特别是方向盘24被冷却/加热到对于将开始行程的人来说舒适的水平。继而，在行程开始时，这减少了车载电池上的负载。此外，该过程允许冷却/加热方向盘24，即使对于在方向盘中未内置有冷却/加热元件的车辆也是如此。
虽然已经详细描述了本发明的某些实施例，但是熟悉本发明所涉及领域的技术人员将认识到用于实践由所附权利要求限定的本发明的各种替代设计和实施例。
