下面结合附图和实施方式对本发明作进一步说明。
参见图1，图1为本发明实施例中触觉反馈的生成方法的步骤流程示意图，本实施例中，上述触觉反馈的生成方法包括：
步骤101、监测预置触摸组件的表面是否有摩擦力产生。
其中，上述触摸组件可以是设置在终端设备显示界面上或者终端设备外壳上的虚拟按键，或者也可以是触摸显示器本身。
当虚拟按键设置于终端设备外壳上时，虚拟按键可位于终端设备外壳的侧面、正面或背面。虚拟按键的材料可以采用具有触摸感应功能的材料或者传感器。当虚拟按键设置于终端设备显示界面上时，该虚拟按键可设置为以一定形状悬浮在屏幕界面上的某一预设区域，或以应用图标的形式显示在当前界面上。
其中，通过触摸、拨动或滑动上述虚拟按键即可以发出触发信号。
可以理解的是，当用户在触摸、拨动或滑动上述触摸组件时，便会在该触摸组件的表面产生摩擦力，该摩擦力包括静摩擦力与滑动摩擦力，因此，通过监测上述触摸组件的表面是否有摩擦力产生，即可监测到用户是否对上述触摸组件进行触摸操作。
步骤102、当监测到所述触摸组件的表面有摩擦力产生时，获取所述摩擦力对应的摩擦力数据。
其中，在监测到触摸组件的表面有摩擦力产生时，即表示用户正在对触摸组件的表面进行触摸操作，此时即可获取上述摩擦力对应的摩擦力数据。
可以理解的是，当触摸组件中不同虚拟按键或不同触摸区域的摩擦力系数不同时，用户在进行触摸操作时，产生的摩擦力也会有所差别，因此通过获取触摸组件表面产生的摩擦力所对应的摩擦力数据，经过分析后即可有助于区分用户的触摸操作，进而产生不同的触摸反馈。
步骤103、根据所述摩擦力数据确定预置马达的驱动参数，并按照所述驱动参数驱动所述马达。
其中，在获取到上述摩擦力数据之后，既可以根据该摩擦力数据确定预置的马达所对应的驱动参数。该马达可以是指线性马达、LRA（Linear
Resonant Actuators，线性谐振制动器）等。摩擦力数据包括摩擦力方向与摩擦力大小等，驱动参数包括马达的振动强度与振动波形等。
其中，可以预先确定一些摩擦力数据样本，如确定一些不同方向、不同大小的摩擦力样本，然后分别对各个摩擦力数据样本对应关联一个马达参数样本，例如，沿终端设备预先设定的X轴滑动，大小为0.1N的摩擦力，其对应的马达振动频率为a；沿终端设备预先设定的X轴滑动，大小为0.2N的摩擦力，其对应的马达振动频率为b，其中，a≠b。然后，建立摩擦力数据样本与马达驱动参数样本之间的对应关系，并保存至终端设备中。
在根据摩擦力数据确定预置马达的驱动参数时，则可以通过查找已保存的摩擦力数据样本与马达驱动参数样本之间的对应关系，确定与上述摩擦力数据对应的马达驱动参数样本，然后将已确定的马达驱动参数样本确定为上述驱动参数。
具体的，以不同的驱动参数驱动上述马达时，马达会产生不同波形或不同强度的振动，从而能够以差异化的反馈方式对用户的触摸操作进行反馈。
本发明实施例所提供的触觉反馈的生成方法，当监测到触摸组件的表面有摩擦力产生时，获取该摩擦力对应的摩擦力数据，然后根据该摩擦力数据确定预置马达的驱动参数，并按照该驱动参数驱动上述马达，即在本发明中，当用户在触摸组件的表面进行触摸或滑动操作时，该触摸或滑动操作能够驱动马达，从而让用户在操作时能够从指间或手掌感受到马达振动反馈，由此可以有效的降低用户误触或重复操作的概率。
进一步地，基于上述实施例，本实施例中，上述触摸组件具体包括虚拟按键，且当该虚拟按键的数量为两个或两个以上时，各个虚拟按键表面的摩擦系数不相同。
由此，上述步骤101中监测预置触摸组件的表面是否有摩擦力产生的步骤具体包括：监测虚拟按键的表面是否有摩擦力产生。
为了便于理解，本实施例以移动终端为例进行说明，手机作为典型的移动终端，其通常都会在机身侧面设置一些案件，如开关按键、音量+按键、音量-按键等。而目前在引入全面屏之后，侧边按键成了各大智能设备厂商都希望用虚拟按键替代的器件，但由于虚拟按键是没有凹凸感的，当用户对其进行操作时，比较容易出现操作失误的情况，如在需要放大音量时误触到音量-按键。
本实施例中，当移动终端上的虚拟按键的数量为两个或两个以上时，将各个虚拟按键表面的摩擦系数设置为不同的数值，例如将“音量+虚拟按键”表面设置为较大的摩擦系数，用于“音量-虚拟按键”表面设置为较小摩擦系数。这样，当用户在触摸“音量+虚拟按键”表面时，就会感受到较大的摩擦力，当用户在触摸“音量-虚拟按键”表面时，就会感受到较小的摩擦力，从而帮助用户区分各个虚拟按键。
进一步的，为了更好的帮助用户区分各个虚拟按键，本实施例中，可以通过检测上述虚拟按键表面产生的摩擦力数据，来确定预置马达的驱动参数，然后通过已确定的驱动参数驱动马达振动，来向用户反馈触摸操作。
例如，可以设定摩擦力越大，马达的振动强度越强，这样，当用户在触摸“音量+虚拟按键”表面时，就会感受到较大的振动感；当用户在触摸“音量-虚拟按键”表面时，就会感受到较小的振动感，从而帮助用户更好的区分各个虚拟按键。
另外，本实施例中，还可以将“音量+虚拟按键”与“音量-虚拟按键”之间的间隙表面的摩擦系数设置为一个不同的系数值，该系数值与 “音量+虚拟按键”、“音量-虚拟按键”表面的摩擦系数均不相同，这样，用户在“音量+虚拟按键”与“音量-虚拟按键”之间来回操作时，若感觉到摩擦力发生短暂的变化，则可以确定此时已从触摸“音量+虚拟按键”转换成了触摸“音量-虚拟按键”，或已从触摸“音量-虚拟按键”转换成了触摸“音量+虚拟按键”。
本实施例所提供的触觉反馈的生成方法，在触摸组件包括虚拟按键的情况下，监测虚拟按键的表面是否有摩擦力产生，当监测到虚拟按键的表面有摩擦力产生时，获取该摩擦力对应的摩擦力数据，然后根据该摩擦力数据确定预置马达的驱动参数，并按照该驱动参数驱动马达。其中，由于当虚拟按键的数量为两个或两个以上时，各个虚拟按键表面的摩擦系数不相同，从而使得用户在触摸不同的虚拟按键时，感受到的摩擦力以及马达振动也会不同，由此便能够帮助用户区分各个虚拟按键，可以有效的降低用户误触或重复操作的概率。
进一步的，进一步地，基于上述实施例，本实施例中，上述触摸组件具体还可以为触摸面板。
由此，上述步骤101中监测预置触摸组件的表面是否有摩擦力产生的步骤具体包括：监测触摸面板表面预设区域是否有摩擦力产生。
为了便于理解，本实施例以车载中控面板为例进行说明，目前的车载中控面板已经可以通过触摸操作来完成大部分的触摸操作，例如在调节空调温度时，便可以通过滑动车载中控面板中的温度控制条或温度控制滚轮来实现。
本实施例中，先监测触摸面板表面预设区域是否有摩擦力产生，该预设区域即为上述温度控制条或滚轮所在的区域；当监测到该预设区域有摩擦力产生时，获取该摩擦力对应的摩擦力数据，然后根据该摩擦力数据确定预置马达的驱动参数，并按照该驱动参数驱动马达，以此来向用户进行反馈。
其中，上述预设区域的摩擦力可以由用户手指的滑动或拖动操作而产生。
即本实施例中，用户在对触摸面板表面预设区域进行滑动或拖动操作时，触摸面板可以通过驱动马达振动的方式来对用户的触摸操作进行实时反馈，从而可以降低用户误触或重复操作的概率。
进一步的，本实施例中，在监测到触摸面板表面预设区域有摩擦力产生之后，且在获取该摩擦力对应的摩擦力数据之前，还包括以下步骤：
确定触摸面板上产生上述摩擦力的触摸区域，以及触摸区域接收到的触摸指令，基于该触摸指令的变化，调节触摸区域的摩擦系数。
为了便于理解，还是以车载中控面板为例进行说明，由于温度控制条或滚轮一般是由一格一格的刻度构成，在从一个刻度变换到另一个刻度时，用户如果不是特别仔细的查看，有可能会滑动超出自己想调节的温度范围，即目前用户在通过触摸调节的过程中，难以确定触控调节的进度。
本实施例中，可以通过确定触摸面板上产生上述摩擦力的触摸区域，以及触摸区域接收到的触摸指令，然后基于该触摸指令的变化，调节触摸区域的摩擦系数，这样以来，触摸面板上产生上述摩擦力就也会随之变化，而进一步确定的马达的驱动参数也会随之发生变化。即随着触摸指令的变化，反馈至用户的摩擦力以及马达振动效果也会同步发生变化。
例如，假设上述温度控制条包括a、b、c、d、e五个刻度，其分别代表五个不同的触摸指令，并且每个刻度所对应的摩擦系数不同。例如，在将温度控制条由b刻度滑动至c刻度时，表示将温度调节至w1℃，此时可以将用户手指所在的区域的摩擦系数从k2调节为k1；在将温度控制条由c刻度滑动至d刻度时，表示将温度从w2℃调节至w3℃，此时可以将用户手指所在的区域的摩擦系数从k1调节为k2；在将温度控制条由d时刻滑动至e刻度时，表示将温度从w3℃调节至w4℃，此时可以将用户手指所在的区域的摩擦系数从k2调节为k1。其中，k1≠k2。
即本实施例中，在用户从“b刻度”滑动至“e刻度”的过程中，用户所感受到的摩擦力变化为F2→F1→F2→F1，其中，摩擦力F1是由摩擦系数k1计算得到的，摩擦力F2是由摩擦系数k2计算得到的。
可以理解的是，本实施例通过上述方式，当用户在触摸面板上滑动时，随着触摸指令的变化，用户所感受到的摩擦力也会随着变化。与此同时，当摩擦力变化时，用户感受到的马达振动效果也会随着变化。
另外，本实施例中，可以采用反向电振动技术、压电陶瓷技术、超声波震动等技术来调节上述触摸区域的摩擦系数。
其中，反向电振动技术是通过用户在使用触摸屏时，向用户全身施加难以察觉的电信号，在皮肤周围形成一个振荡静电场。当用户手指触摸屏幕时，静电力便会改变手指和屏幕之间的摩擦系数。
压电陶瓷技术则主要是把电能转化为机械能，通过屏幕的振动来改变摩擦系数。
超声波震动技术则是使用超声波震动来改变触屏与用户手指间的摩擦系数，该项技术能够使触摸屏幕提供粗糙或是平滑的触觉体验。
应当理解的是，本实施例中所提供的触觉反馈的生成方法，不仅仅可以应用于上述车载中控面板，其还可以应用于其它任意具有触控面板的终端设备，例如手机、平板电脑、智能手表、智能电视、笔记本电脑、游戏机等。
其中，以手机为例，目前大部分的游戏操作（如：上、下、左、右方向控制、枪击、打拳、转弯、加速等）都已经在触屏上使用虚拟按键替代。由于屏幕大小的限制，会出现按键较多，各个按键边界不清晰的情况，导致容易产生误触碰。如果采用上述实施例所提供的触觉反馈的生成方法，便能够根据各个操作指令的变化，向用户反馈差异化的摩擦力与马达振动，使用户在操作上更具有辨识度。
例如，在上、下按键的切换动作之间，可以使用摩擦力结合马达振动，提示用户切换完成。摇杆区域可以依据用户转动遥感的角度或屏幕上特定移动空间，或距离遥杆转动圆心的距离，设定不同的摩擦系数变化，然后利用屏幕表面摩擦力的变化，加上马达振动变化，来模拟按键边缘的边界感、材质杆或摇杆等的阻尼感。
本实施例通过上述方式，用户在触摸面板上滑动时，随着触摸指令的变化，用户所感受到的摩擦力与马达振动效果也会随着变化，即本实施例能够针对用户不同的触摸操作，反馈不同的摩擦力与振动，故能够有效的降低用户误触或重复操作的概率。
进一步的，本发明还提供一种触觉反馈的生成装置200，参照图2，图2为本发明实施例中触觉反馈的生成装置的程序模块示意图。本实施例中，触觉反馈的生成装置200包括：

进一步的，基于上述实施例，本实施例中，上述触摸组件包括虚拟按键，且当该虚拟按键的数量为两个或两个以上时，各个虚拟按键表面的摩擦系数不相同。
其中，监测模块201具体用于：监测所述虚拟按键的表面是否有摩擦力产生。
