 本发明的实施方式
为使得本发明的发明目的、特征、优点能够更加的明显和易懂，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而非全部实施例。基于本发明中的实施例，本领域技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
随着智能设备的进步，用户对操作过程的各种体验要求越来越高，其中触感效果的体验要求也越来越突出。比如，智能设备上的虚拟按键操作中，一个极其短促有力的触感反馈效果不仅可以给操作带来即时的确认感，还可以给人愉悦的满足感。而目前市场上触感效果还停留在简单、缺少精确控制的设计阶段，并且这些触感效果的振动时间长，效果缺少控制，致使触感效果粗糙，无法满足干净迅速、软硬舒适、强弱合理、厚重有力、细致集中等体验要求。
为了解决相关技术中的终端设备所提供的触感效果较为简单且触感效果类型较少的问题，本发明第一实施例提供了一种振动控制方法，如图1为本实施例提供的振动控制方法的基本流程图，该振动控制方法包括以下的步骤：
步骤101、参考触感效果需求指标，在预设振动效果设计模型中获取目标效果参数。
具体的，本实施例的振动效果设计模型中的效果参数基于三个维度设计，具体包括：粒度感参数、锐度感参数以及硬度感参数。如图2所示为本实施例提供的一种振动效果设计模型的示意图，P（a，b，c）表示对触感效果需求进行参数化后所得到的效果参数，振动效果设计模型中不同效果参数对应不同效果质感，其中a反应粒度感参数，b反应锐度感参数，c反应硬度感参数，粒度感、硬度感和锐度感参数的不同组合可以得到任意所期待的效果质感。
其中，粒度感反应效果质感的粗细程度，粒度感越大效果质感越粗糙，反之，效果质感越细致，粒度感采用1~100的量化方式进行参数化，例如，粒度感参数为1时，效果质感最细致，粒度感参数为100时，触感效果的质感最粗糙，有明显沙沙质感；在实际应用中，其它的粒度感参数对应的效果介于最细致和最粗糙之间，具体的对应方式可以是线性的对应关系，也可以非线性的对应方式。
锐度感反应效果质感的锐利程度，锐度感越大效果质感越锐利清晰，反之，效果质感越浑厚；锐度感采用1~100的量化方式进行参数化，例如，锐度感参数为1时，效果质感最锐利，锐度感参数为100时，触感效果的质感最浑厚，有明显沙沙质感；其他的锐度感参数对应的效果介于最锐利和最浑厚之间，具体的对应方式可以是线性的对应关系，也可以非线性的对应方式。
硬度感反应效果质感的软硬程度，采用1~100的量化方式进行参数化，硬度感反应效果质感的强硬冲击程度，硬度感越大效果质感越强硬，反之，效果质感越柔和；例如，硬度感参数为1时，效果质感最柔和，硬度感参数为100时，触感效果的质感最强硬，冲击力最强；其他的硬度感参数对应的效果介于最柔和最强硬之间，具体的对应方式可以是线性的对应关系，也可以非线性的对应方式。
在本实施例的一些实施方式中，上述参考触感效果需求指标，在预设振动效果设计模型中获取目标效果参数的步骤之前，还包括：获取终端当前触发的振动应用场景；根据振动应用场景确定相应的触感效果需求指标。
具体的，在本实施例中，触觉反馈基于终端上的特征振动应用场景触发，而振动应用场景在实际应用中具有多种类型，用户对于不同振动应用场景的触感需求程度有所不同，本实施例根据实时振动应用场景适应性确定触感效果需求指标，以保证触感效果的多样性以及与场景的适用性。应当说明的是，本实施例的振动应用场景可以分为不同层级的振动应用场景，例如上级振动应用场景包括如下任意一种：生物特征识别场景、游戏场景、按键输入场景、通知场景，以上级振动应用场景“按键输入场景”为例，其下级振动应用场景则还可以包括多种细分使用场景：使用拨号盘进行拨号、使用输入法键盘进行文字输入、使用时钟拨盘进行时间设定等，本实施例对此不做唯一限定。
进一步地，在本实施例的一些实施方式中，上述根据振动应用场景确定相应的触感效果需求指标的步骤，包括：根据振动应用场景查询预设的需求指标库；若查询无结果，则基于振动应用场景的场景属性在需求指标库中查询关联振动应用场景；基于需求指标库中关联振动应用场景相应的触感效果需求指标，确定当前触发的振动应用场景相应的触感效果需求指标。
具体的，本实施例的需求指标库包括预设的振动应用场景与触感效果需求指标的映射关系，在实际应用中，考虑到需求指标库在构建时并未全面考量所有实际的振动应用场景，异或在终端使用过程中应用更新而产生新的未预期的振动应用场景，导致实际终端使用过程中所触发的振动应用场景无法在预置需求指标库中查询到相应的触感效果需求指标。基于此，为了保证触觉反馈的正常进行，本实施例分析不同振动应用场景之间的关联性，基于当前振动应用场景在需求指标库中的相似振动应用场景的触感效果需求指标，来模糊设定当前振动应用场景的触感效果需求指标，进而保证需求指标库中未预先覆盖的新振动应用场景均可有效输出触觉反馈。
更进一步地，在本实施例的一些实施方式中，上述基于需求指标库中关联振动应用场景相应的触感效果需求指标，确定当前触发的振动应用场景相应的触感效果需求指标的步骤，包括：获取当前触发的振动应用场景与关联振动应用场景的关联评价指标；参考关联评价指标，对需求指标库中关联振动应用场景相应的触感效果需求指标进行相应调整，得到当前触发的振动应用场景相应的触感效果需求指标。
具体的，为了提高当前触发的振动应用场景相应的触觉效果需求指标的准确性，本实施例对当前振动应用场景与关联振动应用场景的关联性进行评价，也即对两者进行差异分析，根据两者的差异来对适用于关联振动应用场景的触感效果需求指标进行调整，以提高最终所确定的触感效果需求指标与当前振动应用场景的适配性。
进一步地，在本实施例的一些实施方式中，上述根据振动应用场景确定相应的触感效果需求指标的步骤，包括：获取振动应用场景所归属的上级振动应用场景相应的通用触感效果需求指标；其中，上级振动应用场景包括多个细分类型不同的振动应用场景，多个振动应用场景的触感效果需求等级不同；基于振动应用场景的触感效果需求等级对通用触感效果需求指标进行调整，得到相应的触感效果需求指标。
具体的，在本实施例中，上级振动应用场景通常包含众多下级振动应用场景，若分别针对各下级振动应用场景设置对应触感效果需求指标则会导致需求指标库的复杂度较高，基于此，本实施例可以仅在需求指标库中针对上级振动应用场景关联一通用触感效果需求指标，然后上级振动应用场景中各下级振动应用场景均在此通用触感效果需求指标基础上获取相应触感效果需求指标，具体的可以是参考各下级振动应用场景的触感效果需求等级获取相应系数，然后在通用触感效果需求指标基础上乘以该系数即可得到相应的触感效果需求指标，由此，可以有效降低需求指标库的复杂度。
步骤102、根据目标效果参数生成相应振动控制信号。
具体的，本实施例的振动控制信号可以理解为电压信号，该电压信号施加于制动器时，用于激励致动器振动。在实际应用中，该电压信号通常可以为一稳态电压信号，以控制致动器从静止状态达到稳态振动。应当理解的是，针对不同效果参数，该振动控制信号的幅度、频率、周期等有所不同。
步骤103、基于振动控制信号控制致动器振动。
具体的，本实施例的致动器是一种将电能直接转换为机械能的电子器件，致动器通过产生振动以向终端用户输出触觉反馈，应当说明的是，本实施例的应用进程可以为视频、游戏、音乐等，致动器优选的可以为线性马达。
在本实施例的一些实施方式中，前述参考触感效果需求指标，在预设振动效果设计模型中获取目标效果参数的步骤之前，还包括：通过不同振动控制信号激励致动器振动；采集致动器的振动参数以及电压；基于预设响应值计算公式计算致动器的响应值；参考不同响应值分别对振动效果设计模型中不同效果参数相应进行校正。其中，响应值计算公式表示为：dB =mlog{y(n)/x(n)}，dB表示响应值，y(n)表示振动参数，x(n)表示电压，m为自然常数。
如图3所示为本实施例提供的一种致动器性能测试分析系统的结构示意图，本实施例可以将致动器LRA与工装粘性贴合，工装放置在海绵体上以避免环境对测量结果的准确性产生影响，工装上电性连接有加速度计ACC，在实际应用中，在PC上生成的数字信号送入采集卡NI-DAQ进行数模转换得到模拟信号，并通过放大器AMP2对该模拟信号进行放大，然后输出至致动器LRA以激励致动器LRA振动，致动器LRA振动过程中会带动工装反向振动，可以通过加速度计ACC采集工装的振动参数并通过放大器AMP1放大后反馈至采集卡NI-DAQ，另外，采集卡NI-DAQ还对致动器的电压进行回采，最后，PC基于致动器的振动参数以及电压即可计算出不同振动控制信号实际触发的振动响应值。在实际应用中，受客观因素影响，振动控制信号相应的理论振动响应与实际振动响应可能会存在一定差异，本实施例通过对致动器的实际振动效果进行测试，然后参考实际振动响应值对振动效果设计模型中相应效果参数进行校正，可有效提高致动器振动效果的准确性。
在本实施例的一些实施方式中，上述基于振动控制信号控制致动器振动的步骤，包括：对振动控制信号进行放大生成第一控制信号；参考振动控制信号，采用单调递减函数对第一控制信号进行衰减处理，得到第二控制信号；将第一控制信号、第二控制信号以及振动控制信号在时域进行拼接，得到优化后的振动控制信号；按照优化后的振动控制信号控制致动器振动。
具体的，在实际应用中，通过以一个特定周期的稳态电压信号来激励致动器振动时，致动器的前期振动响应存在一定的缓冲过程，用户感知振动的滞后感较大。从而，在本实施例中，对原始振动控制信号进行优化后产生的振动控制信号由第一控制信号、第二控制信号以及振动控制信号三个分段在时域顺序拼接而成，其中，处于前段的第一控制信号输出放大后的启动电压，处于中段的第二控制信号则为电压缓冲区，从启动电压平稳下降至稳态电压，处于后段的振动控制信号则用于持续输出稳态电压，本实施例通过适当调整加速段激励电压，可以有效缩短致动器振动响应前期的加速时间，实现快速达到稳态振动，降低了致动器振动反馈至用户的滞后感。
与相关技术相比，本实施例所提供的振动控制方法，参考触感效果需求指标，在预设振动效果设计模型中获取目标效果参数，其中，振动效果设计模型中的效果参数包括：粒度感参数、锐度感参数以及硬度感参数；根据目标效果参数生成相应振动控制信号；基于振动控制信号控制致动器振动。通过本发明的实施，根据不同触感效果需求场景可适应性设计致动器的振动控制方式，保证了触感效果的多样性以及与场景的适应性，并且致动器的振动效果中考量了多方面的感知因素，可为用户提供更复杂的触觉反馈体验。
为了更好的理解本发明，本发明实施例还提供了一种细化的振动控制方法，图4为本发明第二实施例提供的一种细化的振动控制方法的流程示意图，该振动控制方法包括：
步骤401、获取终端当前触发的振动应用场景，并获取振动应用场景所归属的上级振动应用场景相应的通用触感效果需求指标。
在本实施例中，上级振动应用场景包括多个细分类型不同的振动应用场景，多个振动应用场景的触感效果需求等级不同。
步骤402、基于振动应用场景的触感效果需求等级对通用触感效果需求指标进行调整，得到相应的触感效果需求指标。
具体的，本实施例可以仅在需求指标库中针对上级振动应用场景关联一通用触感效果需求指标，然后上级振动应用场景中各下级振动应用场景均在此通用触感效果需求指标基础上获取相应触感效果需求指标，由此，可以有效降低需求指标库的复杂度。
步骤403、参考触感效果需求指标，在预设振动效果设计模型中获取目标效果参数。
具体的，在本实施例中，振动效果设计模型中的效果参数包括：粒度感参数、锐度感参数以及硬度感参数。
步骤404、根据目标效果参数生成相应振动控制信号。
步骤405、对振动控制信号进行放大生成第一控制信号。
步骤406、参考振动控制信号，采用单调递减函数对第一控制信号进行衰减处理，得到第二控制信号。
步骤407、将第一控制信号、第二控制信号以及振动控制信号在时域进行拼接，得到优化后的振动控制信号。
具体的，在本实施例中，对原始振动控制信号进行优化后产生的振动控制信号由第一控制信号、第二控制信号以及振动控制信号三个分段在时域顺序拼接而成，其中，处于前段的第一控制信号输出放大后的启动电压，处于中段的第二控制信号则为电压缓冲区，从启动电压缓冲至稳态电压，处于后段的振动控制信号则用于持续输出稳态电压。
步骤408、按照优化后的振动控制信号控制致动器振动。
与相关技术相比，一方面，本发明根据不同触感效果需求场景可适应性设计致动器的振动控制方式，保证了触感效果的多样性以及与场景的适应性，并且致动器的振动效果中考量了多方面的感知因素，可为用户提供更复杂的触觉反馈体验；另一方面，本发明通过适当调整加速段激励电压，可以有效缩短致动器振动响应前期的加速时间，实现快速达到稳态振动，降低了致动器振动反馈至用户的滞后感。
