首先参考图1a和图1b说明现有技术中方向盘控制面板组件的控制原理。图1a示出了现有技术中方向盘总成的一个示意图，图1b示出了现有技术中方向盘控制面板组件的一个面板透视示意图。
同时参考图1a和图1b，在现有技术中，方向盘总成10包括方向盘骨架组件11和方向盘控制面板组件12。方向盘控制面板组件12以机械方式(图1a中未示出)装配到方向盘骨架组件11上。方向盘控制面板组件12包括面板121，其中间部分为喇叭功能区122，喇叭功能区122两侧分别设有若干个触摸按键(如字符按键，用于调节音量、温度、激活或取消辅助驾驶功能等)。面板121背侧安装(如紧密粘贴)有触摸检测膜，图1b中的阴影部分为触摸检测膜上分别与每个触摸按键对应的触摸按键检测区123a或123b。触摸检测膜产生检测信号，并提供给方向盘控制面板组件12的控制芯片。
控制芯片在经由触摸检测膜的各个触摸按键检测区的触摸和按压时，向车辆的控制***发送对应的功能触发信号以执行该功能。但是，在车辆转弯时，驾驶员通常需要对方向盘施加控制力，此时，该控制力不可避免地会外溢到面板边缘处，因此需要在驾驶员仅仅是因为转向而误碰到触摸按键时不触发该触摸按键的功能。
有鉴于此，本公开内容提出了一种能够准确地防止按键功能被误触发的方向盘控制组件和按键功能触发方法。下面根据若干个实施例来说明本公开内容的内容。
接下来参考图2和图3，图2示出了根据本公开内容实施例的方向盘控制面板组件的一个面板透视示意图，图3示出了根据本公开内容的一个实施例的按键功能触发方法的一个示意性流程图。
在图2和图3的实施例中，方向盘控制面板组件20包括面板组件、分别位于左右两侧的两个智能开关组件(图中未示出)。面板组件包括面板201。面板201上设有分别位于左右两侧的两个第一区域202a、202b以及 位于它们中间的第二区域203。第一区域202a和202b用作触摸按键的操纵面，第二区域203用作按键功能的操纵面。在面板201背侧与两个第一区域202a和202b对应的位置处分别设有(如粘贴有)触摸检测膜。触摸检测膜例如可以是电容触控膜，其紧密贴合在面板201背侧。电容触控膜可以采用自容或互容类型。第一区域202a和202b中分别布置有若干个触摸按键。相应地，触摸检测膜上设有对应的若干个按键检测区210a和210b，用于检测对象(如驾驶员)对触摸按键的触摸。此外，触摸检测膜上还设有与按键检测区210a和210b不重合的多个非按键检测区，在图2中示例性地示出了左右两侧各三个非按键检测区211a和211b，用于检测对象对第一区域202a和202b中触摸按键之间的空白区域的触摸。在其它实施例中，触摸检测膜上可以设有其它数量的非按键检测区，如四个或六个。面板201可以由低强度且具有一定弹性的材料制成，例如TPO塑料。
以下同时参考图3说明根据本公开内容实施例的按键功能触发方法。图3示出了根据本公开内容实施例的按键功能触发方法的一个示意性流程图。该方法300例如可以由图2中智能开关组件的控制芯片执行，也可以由其它计算设备执行，例如由车辆的控制***执行。
方法300用于车辆的方向盘控制面板组件。方向盘控制面板组件包括具有靠近方向盘边缘的第一区域和靠近方向盘中部的第二区域的面板、设置在面板背侧并与第一区域对应的触摸检测设备(如图3中的触摸检测膜)，其中，所述按键被设置在所述第一区域。
参考图3，在步骤301中，经由所述触摸检测设备检测对象对所述第一区域非按键区域的触摸，并获取触摸检测结果。
如图2中示出的那样，触摸检测膜具有与面板201上的触摸按键对应的多个按键检测区210b以及与按键检测区210b不重合的三个非按键检测区211b。因此，智能开关的控制芯片经由非按键检测区211b检测对象对第一区域202b中触摸按键以外的区域的触摸。触摸检测结果包括每个非按键检测区211b的触摸检测结果。
在步骤302中，基于所述触摸检测结果，判断所述对象是否触摸所述第一区域的非按键区域。
在步骤303中，智能开关的控制芯片经由按键检测区210b检测对象对 第一区域202b中对应的触摸按键的触摸，也就是说，经由所述触摸检测设备检测所述对象对所述按键的按压，并获取按键按压检测结果，以判断所述对象是否按压所述按键。
应当指出，步骤303并非必须要在步骤301和302之后执行，而是可以独立于步骤301和302执行，例如并行地执行或者以相反顺序执行。
在步骤304中，若确定所述对象在按压所述按键之前的第一时间段内未触摸所述第一区域的非按键区域，则触发所述按键功能。以这样的方式使得误触得以避免。
在图3的实施例中，优选地，在所述按键按压检测结果大于1牛顿的情况下，判断出所述对象按压所述按键。更优选地，在所述按键按压检测结果大于2牛顿的情况下，判断出所述对象按压所述按键。此外，优选地，在一些实施例中，所述第一时间段的持续时间不超过1秒。更为优选地，在一些实施例中，所述第一时间段的持续时间不超过400毫秒。在此，所述按键包括靠近方向盘边缘的最外侧字符功能按键。当然，本领域的技术人员应当了解，该按键也能够包括其他按键。换句话说，如果驾驶员在操作时，例如在转向时操作方向盘，先行触碰到非按键区域然后再触碰到按键区域，这通常是误操作，所以不启动按键功能的触发。相应地，如果驾驶员在操作时，例如在转向时操作方向盘，同时触碰到非按键区域并且触碰到按键区域，这通常也是误操作，所以不启动按键功能的触发。本公开内容的发明人意识到只有在确定所述对象在按压所述按键之前的第一时间段内未触摸所述第一区域的非按键区域时才会触发所述按键功能，这将确保按键功能被正确开启。
在图3的实施例中，控制芯片可以生成按键功能触发信号并发送给车辆的控制***。控制***在接收到按键功能触发信号之后，控制该按键对应的功能，并向控制芯片返回结束信息。
在上述实施例中，无需增加硬件成本便能够准确地防止方向盘控制面板上的按键功能被误触发，从而提高了方向盘控制面板的控制性能，避免了潜在的交通违章行为和驾驶安全隐患，提高了用户的驾驶体验，同时还能为面板的外观面造型留下更大的设计空间。
本公开内容还提出了一种按键功能触发装置。按键功能触发装置的各 模块可以利用软件、硬件(例如集成电路、FPGA等)或者软硬件结合的方式来实现。该按键功能触发装置用于车辆的方向盘控制面板组件，所述方向盘控制面板组件包括具有靠近方向盘边缘的第一区域的面板、设置在所述面板背侧并与所述第一区域对应的触摸检测设备，其中，所述按键被设置在所述第一区域。

优选地，在一些实施例中，在所述按键按压检测结果大于1牛顿的情况下，判断出所述对象按压所述按键。更为优选地，在一些实施例中，在所述按键按压检测结果大于2牛顿的情况下，判断出所述对象按压所述按键。
此外，优选地，在一些实施例中，所述第一时间段的持续时间不超过1秒。更为优选地，在一些实施例中，所述第一时间段的持续时间不超过400毫秒。在此，所述按键包括靠近方向盘边缘的最外侧字符功能按键。
在一些实施例中，第一区域包括至少一个触摸按键，触摸检测设备包括触摸检测膜，其具有对应的至少一个按键检测区以及与按键检测区不重合的至少一个非按键检测区。
图5示出了根据本公开内容实施例的计算设备的示意图。计算设备500例如可以上述的智能开关组件的控制芯片。从图5中可以看出，计算设备500包括处理器(例如，中央处理单元(CPU))501以及与处理器501耦合的存储器502。存储器502用于存储计算机可执行指令，当计算机可执行指令被执行时使得处理器501执行以上实施例中的方法。处理器501和存 储器502通过总线彼此相连，输入/输出(I/O)接口也连接至总线。计算设备500还可以包括连接至I/O接口的多个部件(图5中未示出)，包括但不限于：输入单元，例如键盘、鼠标等；输出单元，例如各种类型的显示器、扬声器等；存储单元，例如磁盘、光盘等；以及通信单元，例如网卡、调制解调器、无线通信收发机等。通信单元允许该计算设备500通过诸如因特网的计算机网络和/或各种电信网络与其他设备交换信息/数据。
