具体实施方式
下面详细描述本公开的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本公开，而不能理解为对本公开的限制。
下面参考附图描述本公开实施例的车机屏幕旋转显示方法和装置。本公开实施例的车机屏幕旋转显示方法的执行主体是车辆中可以旋转的车机设备上，该车机设备在旋转时，车机屏幕也会伴随适应性的旋转。
图1是根据本公开一个实施例的车机屏幕旋转显示方法的流程图，如图1所示，该方法包括：
步骤101，获取当前周期的车机屏幕的第一加速度数据，并根据预设的匹配策略确定与第一加速度数据匹配的屏幕显示方向为第一屏幕显示方向。
在本公开的实施例中，可以基于三轴传感器检测加速度数据等，其中，加速度数据应当至少包括水平方向的加速度数据以及竖直方向的加速度数据，其中，基于旋转机制不难理解的是，当车机屏幕的水平方向的加速度数据大于竖直方向的加速度数据的绝对值时，则认为车机屏幕当前的放置方向为竖直放置，从而，如图2-1所示，为了适应这种放置方向，车机屏幕的显示方向应当为竖直方向，当车机屏幕的竖直方向的加速度数据大于水平方向的加速度数据的绝对值时，则认为车机屏幕当前的放置方向为水平放置，从而，如图2-2所示，为了适应这种放置方向，车机屏幕的显示方向应当为水平方向，因而，基于这种旋转规则，构建预设策略，在该匹配策略中包括提取加速度数据中的横向加速度数据(水平方向加速度数据)和纵向加速度数据(竖直方向的加速度数据)，比如可以基于滤波算法提取，当横向加速度数据的绝对值大于纵向加速度数据的绝对值时，确定匹配的屏幕显示方向为竖屏显示方向，当纵向加速度数据的绝对值大于横向加速度数据的绝对值时，确定匹配的屏幕显示方向为横屏显示方向。
当然，在实际执行过程中，根据车机屏幕的放置方向不同，该车机屏幕的旋转方向还可以包括除了横屏显示方向和竖屏显示方向的其他方向，比如，如图2-3所示的倾向纵向的显示方向，以及如图2-4所示的，倾向横向的显示方向等。
在本公开的示例中，获取当前周期内的车机屏幕的第一加速度数据，根据上述预设的匹配策略确定与第一加速度数据匹配的屏幕显示方向为第一屏幕显示方向，其中，在当前周期为初始周期时，为了不影响车机屏幕的正常显示，控制车机屏幕根据第一屏幕显示方向显示。
步骤102，获取下一个周期的车机屏幕的第二加速度数据，并根据预设的匹配策略确定与第二加速度数据匹配的屏幕显示方向，若与第二加速度数据匹配的屏幕显示方向为第二屏幕显示方向，则确定下一个周期为屏幕旋转有效周期。
步骤103，判断屏幕旋转有效周期的连续个数是否超过预设个数，若是，则控制车机屏幕由第一屏幕显示方向旋转为第二屏幕显示方向。
相关技术中，基于每个当前周期内的车机屏幕的加速度数据进行屏幕显示方向的适配，然而，这种适配方式无法屏蔽某些特殊路况下导致的屏幕误旋转，为了解决这种问题，本公开的实施例中，拉长了车机屏幕旋转动作的触发周期，当确定多个后续周期内均需要旋转屏幕时，才进行车机屏幕旋转，保证了车机屏幕旋转的准确，排除了突变情况导致的车机屏幕的误旋转。
在本公开的示例中，在本公开的实施例中，获取下一个周期的车机屏幕的第二加速度数据，并根据预设的匹配策略确定与第二加速度数据匹配的屏幕显示方向，如果与第二加速度数据匹配的屏幕显示方向为第二屏幕显示方向，此时第二屏幕显示方向与第一屏幕显示方向不一样，从而确定下一个周期为屏幕旋转有效周期，其中，在一些可能的示例中，第一屏幕显示方向为横屏显示方向，第二屏幕显示方向为竖屏显示方向，在另一些可能的示例中，第一屏幕显示方向为竖屏显示方向，第二屏幕显示方向为横屏显示方向。
在本公开的实施例中，当确定下一个周期为屏幕旋转有效周期时，并不直接改变车机屏幕的显示方向，而是判断屏幕旋转有效周期的连续个数是否超过预设个数，也就是说是否接下来的多个周期内的加速度数据匹配的屏幕显示方向均为第二屏幕显示方向，如果是，则控制车机屏幕由第一屏幕显示方向选准为第二屏幕显示方向，由此避免了车机屏幕的误旋转。
其中，上述预设个数与加速度数据的采集的周期时长有关，当加速度周期的采集时长较长时，则为了降低屏幕显示方向更改的迟滞，预设个数相对较小，当加速度周期的采集时长较长时，则为了提高屏幕显示方向更改的准确性，预设个数相对较高。
当然，为了提高预设个数的适配性，提高资源利用率，在本公开的一个实施例中，根据路况信息来调整预设个数，在本实施例中，如果路况相对较为平整，比如处于较为平坦的高速公路上行驶，则认为发生颠簸等情况的概率较低，从而，认为旋转事件的误触发概率较低，设置的预设个数较低，反之，当路况较为复杂，比如，处于较为颠簸的山路地段，则认为发生颠簸等情况的概率较高，从而，认为旋转事件的误触发概率较高，设置的预设个数较高。
在本公开的示例中，在本示例中，获取车辆当前行驶的路况信息，比如，可以基于定位位置识别当前行驶的路况信息，比如，当前位置在山区，则路况信息为有关地图中显示 的该山区的地图，或者，可以基于车辆中的摄像头采集得到的路面情况作为路况信息，进而，基于路况信息识别路况特征，比如识别是否具有山地，是否具有高度路线等，进而，根据路况特征调整预设个数，当属于高速路等较为平坦的路况特征时，将预设个数调整为相对较低值，当属于山地等较为颠簸的路况特征时，将预设个数调整为相对较高值。
为了使得本领域的技术人员更加清楚的了解本公开实施例的车机屏幕旋转显示方法，下面结合在本公开的示例中示例进行说明，在该示例中，预设个数为10，横向加速度数据为x轴加速度数据，纵向加速度数据为y轴加速度数据，说明如下：
如图3所示，车机系统上电后，传感器数据上电初始化，周期性的检测三轴原始数据，如果为首次获取到三轴加速度数据，则判断x轴加速度数据的绝对值是否大于y轴加速度数据的绝对值，若大于，则上报竖屏状态，并对数据状态进行记录，如果不大于，则判断y轴加速度数据的绝对值是否大于x轴加速度数据的绝对值，若是，则上报横屏数据，并记录数据状态。
如果不是首次获取到三轴加速度数据，则判断上一次屏幕状态是否为横屏，若是，则判断后续周期内x轴加速度数据的绝对值是否大于y轴加速度数据的绝对值，如果是，则记录x轴加速度数据的绝对值大于y轴加速度数据的绝对值的次数x-count，判断x-count是否为10，若是，则对x-count清零并上报竖屏数据，若没有达到10就出现了x轴加速度数据的绝对值小于y轴加速度数据的绝对值的情况，则上报横屏数据。
在本实施例中，若上次车机屏幕的显示状态为竖屏状态，则确定后续周期内y轴加速度数据的绝对值是否大于x轴加速度数据的绝对值，若是，则记录y轴加速度数据的绝对值大于x轴加速度数据的绝对值的次数y-count，判断y-count是否为10，若是，若是，则对y-count清零并上报竖横屏数据，若没有达到10就出现了x轴加速度数据的绝对值大于y轴加速度数据的绝对值的情况，则上报竖屏数据。
综上，本公开实施例的车机屏幕旋转显示方法，获取当前周期的车机屏幕的第一加速度数据，并根据预设的匹配策略确定与第一加速度数据匹配的屏幕显示方向为第一屏幕显示方向，获取下一个周期的车机屏幕的第二加速度数据，并根据预设的匹配策略确定与第二加速度数据匹配的屏幕显示方向，若与第二加速度数据匹配的屏幕显示方向为第二屏幕显示方向，则确定下一个周期为屏幕旋转有效周期，进而，判断屏幕旋转有效周期的连续个数是否超过预设个数，若是，则控制车机屏幕由第一屏幕显示方向旋转为第二屏幕显示方向。由此，避免了车机屏幕的误旋转，提高了用户和产品之间的粘性。
为了实现上述实施例，本公开还提出了一种车机屏幕旋转显示装置，图4是根据本公开一个实施例的车机屏幕旋转显示装置的结构示意图，如图4所示，该车机屏幕旋转显示 装置包括：第一确定模块100、第二确定模块200、第三确定模块300和处理模块400。
其中，第一确定模块100，用于获取当前周期的车机屏幕的第一加速度数据，并根据预设的匹配策略确定与第一加速度数据匹配的屏幕显示方向为第一屏幕显示方向。
