马达软件系统将马达振动波形输入到马达驱动芯片中,进而驱动马达按照马达振动波形振动。不同的马达振动波形能给用户带来不同的振动体验,如图3所示,若马达振动波形较平缓如波形1和波形2,当手机振动时,可能手机振感较为和缓,持续时间较长,用户的振动体验也会较为平和;若马达振动波形较为尖锐如波形3,当手机振动时,可能手机振感较为强烈,持续时间较为短促,用户会获得较为刺激的振动体验。其中,形状相似的马达振动波形能给用户带来相似的振动体验,但振动量不同,用户所能感受到的振感强度会不同。比如某两个马达振动波形均为较平缓的波形,其中一个波形的振动量为0.8g,另一个波形的振动量为0.4g,那么用户会感觉振动量较大的振动波形振感更为强烈。
在一些实现方式中,可以预先设计不同的马达振动波形,将这些马达振动波形保存至马达波形库。在马达波形库中,可对马达振动波形进行编号,便于后续调用不同的马达振动波形号即可调用对应的马达振动波形。
可选的,在本申请实施例的一些实现方式中,根据用户振动体验等条件将马达波形库中的振动波形进行分类。如图4所示,示例性的给出了四种不同的包含峰值波形的部分马达振动波形,可以根据用户振动体验将这四个振动波形分为两组,第一组为用户振动体验较为和缓的振动波形包括图4中的(a)和图4中的(b)两个波形。这两个波形形状相似但振动量不同,则用户虽然可以获得相似的振动体验,但振感强度不同。第二组为用户振动体验较为刺激的振动波形包括图4中的(c)和图4中的(d)两个波形,这两个波形形状相似,则用户可以获得振动体验相似的振动。
不同的马达振动波形为用户带来的振动体验不同,手机厂家预配置上述马达波形库。在开发过程中,手机厂家从马达波形库中为不用应用或手势选择马达振动波形;第三方应用开发商在第三方应用开发过程中,从马达波形库中选择马达振动波形。将预配置的不用应用或手势对应的马达振动波形情况存储于电子设备100的内部存储器121中。其中,马达波形的存储有两种方式:一种是存储马达振动波形数据,即将马达振动波形存储于内部存储器121中,需要时直接调用对应的马达振动波形。另一种是存储马达振动波形参数,如输入电压特征值、输入电流特征值等。即将输入电压特征值、输入电流特征值等马达振动波形参数存储于内部存储器121中,需要时调用对应的马达振动波形参数,根据马达振动波形参数生成马达振动波形数据。实际应用中,当手机检测到用户的某些操作时,手机驱动马达按照不同的振动波形振动,使得用户可以根据振动体验直接判断当前操作是否正确。比如,单击对应波形1,双击对应波形2,长按对应波形3。波形1、波形2和波形3为波形不同的马达振动波形,振动体 验差别较大,进而用户执行双击后可以根据振动体验感应当前振动波形是否为振动波形2,进而判断手机是否检测到该双击操作,若检测错误,如手机检测为单击操作,驱动马达按照波形1振动,则用户可以根据振动体验感知到该操作异常,重新进行单击操作。又比如,为短息和电话设置不同的振动模式(不同的振动波形),当手机接收短息或接收来电后,用户可以不必查看手机屏幕,根据振动体验的不同就能获知当前振动提示为新信息或新来电。
在本申请实施例的一些实现方式中,可以通过降低马达191的振动功耗,以适应于电池142带载能力较低的场景,如电池温度较低和/或电池电量较低的场景。具体的,可以通过采用功耗较低的振动波形或降低输入电压的方式以降低马达191振动时产生的瞬间振动峰值电流,进而有效的防止电池142超载掉电。
一般地,马达振动波形的振幅越小,电压、电流值越小,功耗越低。如图3所示,示例性的给出了输入电压或电流随时间的变化生成的马达振动波形。比如,波形1和波形2为两个用户振动体验类似的马达振动波形,波形2比波形1振幅小,即波形2的振动电流比波形1的振动电流小,则波形2的功耗比波形1的功耗低。如此,若手机之前某应用对应的马达振动波形为波形1,当手机处于带载能力较低的场景,需要选择相似用户振动体验且功耗较小的振动波形时,马达软件系统可以选择波形2输入到马达驱动芯片中,驱动马达按照波形2振动。
本申请实施例提供的一种马达振动控制方法。如图5所示,该方法可以包括以下步骤:
S101、手机发送马达振动请求。
在一种可能的实现方式中,当手机收到提醒时,如收到来电信号或短信信号时,需要马达振动以提示用户,或者手机检测到用户的一些操作时,需要进行触摸振动反馈用户。此时,手机发送马达振动请求至上述马达软件系统205,进而驱动马达振动。在马达振动请求处理过程中,需要确定马达振动波形,此时,手机会查询当前电池状态,以匹配对应的马达振动波形或输入电压。
需要说明的是,在本申请实施例中,当马达软件系统205接收到马达振动请求时(马达振动波形可以静态存储,也可以动态加载),判断需要的马达振动波形,并将振动命令下发到马达驱动芯片202,驱动马达191振动。
S102、手机查询电池状态。
在一种可能的实现方式中,参见图2,手机可以从电池供电系统201或电池管理软件系统204查询当前电池状态,该电池状态包括电池温度,或者电池温度及电池电量,或者电池供电能力。该电池状态用于后续判断是否需要降低马达振动功耗。当需要降低马达振动功耗时,可以根据当前电池状态数据判断需要切换的马达振动参数。该马达振动参数可以包括马达振动波形或马达振动波输入电压。可以理解的是,马达波形库中的马达振动波形具有编号,当需要切换马达振动参数为马达振动波形时,该马达振动参数即为马达振动波形编号,调用马达振动波形编号即可调用对应的低功耗马达振动波形。
S103、手机确定是否需要降低马达振动功耗。若是,执行步骤S104,即切换低功耗马达振动参数。若否,执行步骤S105,即继续使用当前马达振动参数驱动马达振动。
在一种可能的实现方式中,设定预设条件,当电池状态满足预设条件时,判断当前需要驱动马达低功耗振动,以防止高功耗马达振动的瞬间峰值电流高于电池的供电电流,导致手机异常关机。其中,预设条件为:电池供电能力低于第一阈值,或者当前电池温度低于第二阈值,或者当前电池温度&电池电量低于第三阈值数组。第一阈值和第二阈值和第三阈值可以根据电池建模数据、测试数据以及经验数据获得,预先配置于手机等终端中。手机可以根据电池状态参数及第一阈值和第二阈值和第三阈值判断当前是否需要驱动马达低功耗振动。若需要驱动马达低功耗振动,则手机需要切换马达振动参数,驱动马达低功耗振动;若不需要低功耗处理,则手机可以继续按照当前马达振动参数驱动马达振动。
S104、手机切换马达振动参数。
通过切换马达振动参数的方式降低马达振动时产生的瞬间峰值电流,进而降低马达振动功耗,防止电池过载。其中,切换马达振动参数包含如下方式:
方式一:
在一种可能的实现方式中,根据手机供电能力,切换低功耗振动波形驱动马达振动,例如:可以根据电池供电能力划分不同的供电能力档位,如1A-1.1A,1.1A-1.2A等。选择峰值电流小于手机的最大供电电流(对应供电能力档位下限)的振动波形,进而有效的降低马达振动功耗。其中,可以根据电池温度及电池电量获得手机供电能力档位,也可以由电池管理软件系统直接获得供电能力值,主要包括手机的最大供电电流值。
为了保证用户振动体验,当手机电池负载能力较低,需要切换低功耗波形时,手机可以为用户切换振动体验类似的低功耗波形。如下表2所示,示例性的给出上述马达波形库中波形相似,用户振动体验类似的4个波形36-39号波形,即这四个波形属于同一分类组。表2中还包括44号波形,该44号波形属于另一组低功耗波形,与36-39号波形的振动体验不同。为了统一度量标准,保证获得同一电压条件下的振动峰值电流,需将电压归一化处理。下表2为将电压归一化到3.8V时,不同马达振动波形的振动量和振动峰值电流。
表2
可选的,当电池带载能力降低,某一应用或手势需要振动反馈时,可以根据当前电池的供电能力,在预配置的马达波形库中选择与操作该应用或手势对应的振动波形振动体验相似的低功耗波形。比如,原马达振动波形为36号,当电池带载能力降低时,可以将马达振动波形切换为37号。
可选的,电池温度及电池电量会对电池供电能力产生影响。由此,可以根据电池供电能力及马达振动峰值电流选择当前温度及电量条件下可用的马达振动波形,即选择的振动波形的振动峰值电流要低于电池的供电能力,使得电池当前的供电电流满足马达振动所需,而不会造成手机电池超载异常。
比如,根据表1及表2得到下表3,手机根据当前电池温度及电池电量判断当前电池供电能力,进而根据电池供电能力匹配对应的低功耗马达振动波波形,驱动马达振动。

表5

可选马达振动波 | 38 | 38 | 39 | 39 |
又比如,手机可以直接获得电池供电能力时,参见下表6,手机可以直接根据当前电池供电能力匹配对应的低功耗马达振动波波形,驱动马达振动。
表6
供电能力(A) | 1.5 | 1.2 | 0.95 | 1.4 | 1.26 | 0.94 | 0.78 | 0.568 |
可选马达振动波 | 38、39 | 38、39 | 39 | 38、39 | 38、39 | 39 | 39 | 39 |
可选的,当存在多个可选的马达振动波形时,可以在多个可选的马达振动波形中,根据用户实际体验需求进行选择。比如,相似振动体验的波形中,可以根据振动量的大小选择对应的波形,振动量大对用户的振感也会较为强烈。参见表3,当当前电池温度为-5℃,电池电量为30%时,可选的振动波形有两个为38号和39号。示例性的,可以选择振动量较大的马达振动波形,用户可以获得较大振感的振动体验。如选择38号振动波形驱动马达振动。或者,若用户处于较为嘈杂的环境中(如用户正在逛街),参见表2,则可以选择振动量较大的38号振动波形驱动马达振动,以便用户可以快速感知该振动。或者,若用户处于较为安静的环境中(如用户正在图书馆看书),参见表2,则马达可以选择振动量较小的39号振动波形实现振动,以使用户可以感知该振动,而又不会影响到其他读者。
可选的,可以在马达波形库中,建立一组通用低功耗马达振动波形。参见下表6,该通用低功耗马达振动波形组包括90-94号低功耗马达振动波形。将电池供电能力按照一定的区间进行划分,每一区间对应该通用低功耗波形组中的一个波形,当手机在 马达波形库中选择用户振动体验相似的波形时,未能匹配到对应的波形,手机可以选择当前电池供电能力大于等于表4中供电能力下限对应的通用低功耗波形,进而实现切换低功耗波形,防止电池超载。比如,当前电池供电能力为0.94A,未能匹配到与当前马达振动波形的具有相似用户振动体验的低功耗马达振动波形。此时,可以参见下表7,0.94A>0.7A,选择91号马达振动波形驱动马达振动。
表7
电池温度(℃) | -25 | -20 | -5 | -5 | -5 |
电池电量(%) | 20 | 40 | 15 | 20 | 30 |
供电能力下限(A) | 0.3 | 0.7 | 1 | 1.2 | 1.5 |
可选马达振动波形 | 90 | 91 | 92 | 93 | 94 |
需要说明的是,上述表1和表2仅为示例性的给出部分电池状态条件及部分马达振动波参数。由此,可以理解的是,表3、表4及表5应该还可以包括更多电池状态条件及对应的可选马达振动波形。并且上述表2、表3、表4、表5及表6均为将电压归一化到3.8V时,确定振动峰值电流,进而选择可选的振动波型号。该对于电压的归一化处理目的为统一度量标准,保证获得同一电压条件下的振动峰值电流,该归一化电压也可以为其他数值,如4.2V等,本申请实施例不做具体限定。
进一步的,上述表3、表4、表5及表6中,选择可选马达振动波形的过程中,仅考虑马达振动峰值电流需小于电池供电能力,可以理解的是,由于电池还需要为手机中其他部件供电,因此,可以设定预设阈值,当马达振动峰值电流与电池供电能力的电流差值大于预设阈值时,对应的振动波形为可选的马达振动波形,该预设阈值可以为试验获得的经验数据,本申请实施例不做具体限定。
如此,如表3、表4、表5及表6所示,建立电池温度,电池电量,供电能力与可选振动波型号的对应关系表存储于手机存储器中。当手机判断当前马达需要低功耗振动时,可以利用对应的表格,匹配用户振动体验类似的振动波形中对应的可选马达振动波形。
方式二:
在一种可能的实现方式中,改变驱动马达振动的输入电压,以降低马达振动时产生的功耗。比如,可以根据电池的供电能力(供电电流)获得当前可以提供的驱动马达振动的输入电压。示例性的,可以利用公式v=k*i*(V/I),建立电压和电流的峰值关系,进而获得对应的低功耗输入电压。其中,V表示原马达振动波形的峰值输入电压;I表示原马达振动波形的供电电流;v表示当前电池状态条件下需要的马达振动波形的低功耗峰值输入电压;i表示当前电池给马达供电电流能力;k表示马达系数,和马达规格、马达设计系统相关,不同的马达规格、马达设计系统测出来的经验k值不一样。示例性的,当k=1时,由上述公式可以获得v/i=V/I,即可获得当前实现马达振动的输入电压,该输入电压为马达振动波形的峰值电压。根据该峰值电压和当前马达振动波形的峰值电压计算压缩比例,将当前马达振动波形按照该比例等比例压缩,得到切换后的马达振动波形,有效降低马达振动功耗。
可选的,可以将上述按比例压缩后的马达振动波形存储到上述方式一中的马达波形库中,进而,当后续再次需要该马达振动波形时,可以直接调用该马达振动波形, 而不必再次进行计算。
需要说明的是,计算马达振动波形的输入电压,还可以和具体的马达模型建模相关。当手机厂商为手机配置马达时,会对影响马达质量的参数进行建模训练验证,筛选出较优的参数,以控制马达质量。不同型号及质量的马达,在输入电压的实现上会存在偏差。当厂家利用马达模型为手机配置马达后,手机根据上述公式获得输入电压即可,而不必再考虑不同的马达模型对输入电压的影响。
如此,当手机带载能力降低,需要马达更换参数时,可以首先在手机预配置的马达波形库中根据电池供电能力,或电池温度及电池电量匹配可选的用户振动体验相似的低功耗马达振动波形。若未能在马达波形库中匹配到可选的马达振动波形,那么,也可以利用上述公式确定当前电池状态可为马达提供的输入电压,进而使电池提供该按比例压缩的输入电压,实现马达的低功耗振动。或者,当未能在马达波形库中匹配到可选的用户振动体验相似的马达振动波形时,可以匹配满足当前供电能力的通用的低功耗马达振动波形,以降低马达振动功耗,防止手机异常掉电关机。
S105、手机驱动马达振动。
在一种可能的实现方式中,当步骤S103中,手机确定当前电池状态可以满足当前马达振动条件,即不必低功耗振动时,不必执行步骤S104,而直接执行步骤S105,手机利用当前马达振动参数驱动马达振动。
在一种可能的实现方式中,马达软件系统匹配到上述切换后的低功耗马达振动参数后,根据该振动参数驱动马达振动为用户提供振动反馈,实现在电池低带载能力条件下的马达振动。
在又一种可能的实现方式中,可以在马达中增加大电容器件,用于对马达振动波形的振动峰值进行滤波,实现平滑峰值电流。即使得马达振动时不会产生加大的瞬时电流,进而不会超过电池的供电能力,使电池过载。在电池带载能力较低的条件下,也可以保证手机振动功能而不会造成振动导致的手机异常掉电关机。
在又一种可能的实现方式中,当步骤S103中,手机确定马达需要低功耗振动,即手机判断当前场景为手机带载能力较低的场景时,可以使手机电池的输出电压中马达振动时使用电压的峰值和高功耗应用使用电压的峰值实现错峰供应。即,将防止马达振动波形达到峰值时,同时运行高功耗应用,导致瞬时电流过高,电池过载掉电。示例性的,手机拍照时,快门按下拍照瞬间,瞬时峰值电压较高,此时,若有来电或短消息提醒振动,可以将该马达振动的峰值与拍照电压的峰值在时间上分离,以保证当前电池状态的供应能力足够实现当前马达振动波形的振动。
由此可见,本申请提供的一种马达振动控制方法,可以在电池带载能力低的场景下,通过切换低功耗马达振动波形或改变马达振动波形输入电压,动态调整马达振动功耗,实现低功耗马达振动,而不会造成手机异常掉电关机。以改善现有技术中,当手机处于电池带载能力低的场景下时,禁用马达振动功能,使得用户体验感较差的问题。
