Description

汽车转向盘及车载电子设备交互控制方法 技术领域
本发明涉及汽车电子技术领域，尤其涉及一种汽车转向盘及车载电子设备交互控制方法。
背景技术
目前，对于车载电子设备的交互控制，一方面可以通过设置于汽车中控台上的功能按钮或者触控式中控屏来实现，另一方面可以通过集成于多功能转向盘上的功能按钮来实现。然而，由于中控台离驾驶位较远，驾驶人在对中控台上的功能按钮或触控式中控屏进行操作时，需要将视线朝向中控台方向偏移，存在驾驶安全隐患。同时，多功能转向盘上的功能按钮大都集中在一个较小的按键区域，且按钮的接触面积小，需要驾驶人依靠触感或通过视觉分离进行精确的定位方可进行操作，同样容易造成驾驶人分神，不利于提升汽车驾驶的安全性。
发明内容
鉴于现有技术中存在的上述问题，本发明实施例提供一种汽车转向盘及车载电子设备交互控制方法，以简化车载电子设备交互控制操作，提升汽车驾驶的安全性。
一种汽车转向盘，包括：主控板、传感器模块、盘毂、辐条及盘缘，所述盘毂通过所述辐条与所述盘缘连接；
所述传感器模块用于检测所述汽车转向盘的转动方向及转动角度；
所述盘缘的表面设置有触摸感测器件，所述触摸感测器件包括位置坐标可配置的第一触摸区域和第二触摸区域；
所述主控板用于根据所述汽车转向盘的转动方向及转动角度，将所述第一触摸区域和所述第二触摸区域的位置坐标分别配置为与汽车驾驶位的左右两侧相对；
所述第一触摸区域和/或所述第二触摸区域用于接收触控手势，所述主控板还用于根据所述触控手势对车载电子设备进行交互控制。

根据所述汽车转向盘的转动方向及转动角度，将所述第一触摸区域和所述第二触摸区域的位置坐标分别配置为与汽车驾驶位的左右两侧相对；
通过所述第一触摸区域和/或所述第二触摸区域接收触控手势，并根据所述触控手势对车载电子设备进行交互控制。
所述汽车转向盘通过在盘缘上设置所述触摸感测器件，且将所述触摸感测器件上的第一触摸区域和第二触摸区域的位置坐标设置为可配置的，进而通过所述传感器模块检测汽车转向盘的转动方向及转动角度，并根据所述转动方向和转动角度将所述第一触摸区域和所述第二触摸区域的位置坐标分别配置为与汽车驾驶位的左右两侧相对，以方便驾驶人对所述第一触摸区域和/或所述第二触摸区域进行触控手势操作，进而根据所述触控手势对车载电子设备进行交互控制。由于所述第一触摸区域和所述第二触摸区域始终位于驾驶位的左右两侧，可以提升驾驶人的操作舒适性，同时，仅需通过触控手势即可实现对车载电子设备的交互控制，极大地简化了车载电子设备的交互控制操作，有利于提升汽车驾驶的安全性。

其中，所述车载电子设备可以包括但不限于音响、空调、蓝牙电话等。所述主控板120可以通过有线或无线的方式与所述车载电子设备建立电连接关系，进而通过有线通信或无线通信的方式将交互控制信号传输给所述车载电子设备。
在一种实施方式中，所述第一触摸区域141与所述第二触摸区域143的分界线经过所述盘缘150的中心，所述第一触摸区域141的位置坐标和所述第二触摸区域143的位置坐标由所述分界线的坐标确定。所述主控板120还用于根据所述汽车转向盘100的转动方向及转动角度，配置所述第一触摸区域141和所述第二触摸区域143的分界线相对于所述柔性触摸板140的转动方向及转动角度。
可以理解，所述第一触摸区域141和所述第二触摸区域143的分界线相对于所述柔性触摸板140的转动方向与所述汽车转向盘100的转动方向相反，所述第一触摸区域141和所述第二触摸区域143的分界线相对于所述柔性触摸板140的转动角度与所述汽车转向盘100的转动角度相同。
请参阅图2，若将所述柔性触摸板140展开，得到一带状的柔性触摸板。假设沿所述柔性触摸板140的长度方向的坐标轴为X，沿所述柔性触摸板140的宽度方向的坐标轴为Y，则所述所述第一触摸区域141和所述第二触摸区域143的位置坐标可以由坐标轴X上的两条分界线确定。可以理解，当所述柔性触摸板140首尾拼接并设置到所述盘缘150上时，所述两条分界线的连线经过 所述盘缘150的中心。
请参阅图3，若X的取值范围为0-999，且初始情况(即所述汽车转向盘100处于回正状态)下，所述第一触摸区域141的位置坐标在X轴上的取值范围为0-499，所述第二触摸区域143的位置坐标在X轴上的取值范围为500-999，且所述第一触摸区域141和所述第二触摸区域143的位置坐标分别与汽车驾驶位的左右两侧相对。
请参阅图4，在一种实施方式中，若所述汽车转向盘100顺时针转动了90度，为将所述第一触摸区域141和所述第二触摸区域143的位置坐标分别配置为与汽车驾驶位的左右两侧相对，需要将所述第一触摸区域141的位置坐标在X轴上的取值范围调节为750-999、0-249，并将所述第二触摸区域143的位置坐标在X轴上的取值范围调节为250-749。可以理解，由于所述柔性触摸板140相对于所述盘缘150静止，在完成调节之后，所述第一触摸区域141和所述第二触摸区域143的分界线相对于所述柔性触摸板140逆时针转动了90度。
在一种实施方式中，所述主控板120还用于检测所述触控手势的触控位置坐标，并根据所述触控位置坐标的轨迹确定所述触控手势。可以理解，由于驾驶人在用触控手势操控所述柔性触摸板140时，手掌与所述柔性触摸板140之间可能同时存在多个接触点。在本实施例中，选取由所述触控手势在所述第一触摸区域141和/或所述第二触摸区域143形成的多个触控接触点围成的区域的几何中心作为所述触控手势的触控位置坐标。
在一种实施方式中，所述触控手势包括在所述第一触摸区域141的滑动手势，所述主控板120还用于根据所述滑动手势控制车载电子设备切换交互控制菜单。其中，所述滑动手势沿所述X轴方向滑动，即沿所述盘缘150的圆周方向的滑动。例如，所述交互控制菜单可以包括车载电子设备中不同功能的菜单选项，如空调、音响、蓝牙电话等，通过在所述第一触摸区域141的滑动手势，可以将菜单的选择光标在空调、音响、蓝牙电话功能菜单之间切换。
在一种实施方式中，所述触控手势还包括在所述第一触摸区域141和所述第二触摸区域143的同步双击手势，所述主控板120还用于根据所述同步双击手势控制车载电子设备选择交互控制菜单中的当前选项。其中，所述同步双击手势是指在预设时间间隔内，驾驶人双手连续两次同步轻拍所述第一触摸区域 141和所述第二触摸区域143。例如，当通过在所述第一触摸区域141的滑动手势将菜单的选择光标切换到音响功能菜单上时，进一步通过所述同步双击手势即可完成对所述音响功能菜单的选择。可以理解，所述音响功能菜单还可以包括多个子菜单，例如音量控制菜单、歌曲切换菜单等，因而可以进一步通过在所述第一触摸区域141的滑动手势切换对应的子菜单，并通过所述同步双击手势选择对应的子菜单，例如音量控制菜单。
在一种实施方式中，所述触控手势还包括在所述第二触摸区域143的滑动手势，所述主控板120还用于根据所述滑动手势控制车载电子设备调节所述被选择的当前选项的参数。其中，所述在所述第二触摸区域143的滑动手势与所述在所述第一触摸区域141的滑动手势相同，即沿所述X轴方向的滑动。例如，当通过所述同步双击手势完成对所述音量控制菜单的选择之后，可以进一步通过在所述第二触摸区域143的滑动手势来对所述音量控制菜单的参数进行调节，例如通过朝向远离驾驶位的方向滑动来增大音量或通过朝向驾驶位的方向滑动来减小音量。
在一种实施方式中，所述触控手势还包括在所述第一触摸区域141和所述第二触摸区域143的同步三击手势，所述主控板120还用于根据所述同步三击手势控制车载电子设备退出当前层级的交互控制菜单，并返回上一层级的交互控制菜单。其中，所述同步三级手势是指在预设时间间隔内，驾驶人双手连续三次同步轻拍所述第一触摸区域141和所述第二触摸区域143。例如，在完成对音量的调节之后，可以通过所述同步三击手势退出音量控制菜单。
可以理解，在本发明实施例的任一种实时方式中，在通过所述触控手势对所述车载电子设备进行交互控制时，还可以通过车载音响同步播放对应交互控制菜单的语音提示，例如，当选择光标切换到音响功能菜单上时，则可通过语音提示驾驶人当前菜单为音响功能菜单；此外，还可以通过车载中控台上的中控屏显示对应的交互控制菜单。
