为使本发明的上述目的、特征和优点能够更加明显易懂,下面结合附图和具体实施方式对本申请做进一步详细的说明。
实施例1
本实施例提出的一种振动信号的校准方法,所述振动信号用于驱动一校准马达振动,请参阅图1,所述振动信号的调整方法包括:
S1、确定一预置马达的振动效果参数与一预置马达的校准参数的映射关系。
具体来说,需要先确定振动效果参数与校准参数的映射关系才能进行后续的校准操作。以下对上述步骤S1中的各个参数进行解释:
预置马达为虚拟的马达模型,在一些场景下可以用来模拟实际的马达。
振动效果参数为体现马达的振动效果的参数。更具体的,振动效果参数为体现马达振动刹车效果的参数。
结构参数为只与马达自身构造相关的参数,更具体的,结构参数包括会影响马达振动的参数,比如弹簧劲度系数、马达音圈电感系数、马达电磁力系数或阻尼器的力阻系数等。在本实施例中,结构参数为支撑所述马达振动的弹性件的弹簧劲度系数。
校准参数为体现马达的结构参数与马达的振动位移的关系的参数。更具体的,校准参数为一位移偏移量,具体为:在以马达的振动位移为横坐标(横坐标的正方向为马达的初始位移方向)、以结构参数为纵坐标的坐标系中,结构参数的极值点所对应的位移值与位移原点的差值。
进一步地,所述步骤S1包括:
若干次改变所述预置马达的结构参数,驱动配置了每一结构参数的预置马达并获取相应的校准参数的值和相应的振动效果参数的值,以生成所述映射关系。
具体来说,在一次改变预置马达的结构参数后用一振动信号驱动该预置马达,可以获取一个结构参数的极值点,该极值点与位移原点的差值就为一个校准参数(即一个位移偏移量);另外,驱动后还可以获取一个振动效果参数,也就是说,一次改变预置马达的结构参数,可以获取到一个校准参数与一个对应的振动效果参数。因此,通过若干次改变预置马达的结构参数并用同一个振动信号去驱动,就可以得到若干个校准参数和若干个对应的振动效果参数。如此,通过若干个校准参数和若干个对应的振动效果参数,就可以生成振动效果参数与校准参数的映射关系。
在本实施例中,请参阅图2,通过若干次改变预置马达的弹簧劲度系数并用同一振动信号驱动,得到振动效果参数与校准参数的映射关系。
S2、提供一初始振动信号X,驱动所述校准马达振动,并获取所述校准马达的所述校准参数的检测值。其中振动信号为电压信号。
具体来说,在马达的批量使用中都采用固定的信号(即初始振动信号X)进行驱动,但由于结构参数的原因,每一个马达单体(即一校准马达)都需对初始振动信号X做适应性校准。因此,步骤S2用于获取用于校准的检测值。
进一步地,所述步骤S2还包括:
所述校准马达振动后,采集所述校准马达的加速度、电压、电流中的至少一者,以计算获得所述校准马达的所述结构参数与所述校准马达的振动位移的关系。
具体来说,用初始振动信号X驱动校准马达振动后,通过采集校准马达的加速度、电压、电流中的至少一者,进行计算后即可得到校准马达的结构参数与其振动位移的关系,进而获取关系曲线的极值点,该极值点所对应的振动位移与位移原点之间的差值即为检测值。
在本实施例中,请参阅图3,用初始振动信号X驱动校准马达后,通过采集加速度、电压和电流后生成弹簧劲度系数与振动位移的关系,从关系曲线图可知,极值点所对应的位移与位移原点之间的差值大约为0.1mm。
S3、对照所述映射关系,判断对应所述检测值的负值的振动效果参数的值是否优于对应所述检测值的振动效果参数的值,若是,则设置所述振动信号为-X,若不是,则设置所述振动信号为X。
具体来说,在步骤S2中得到的检测值,通过步骤S1得到的映射关系,判断检测值的负值所对应的振动效果参数的值是否优于与检测值所对应的振动效果参数的值。若优于,则将初始振动信号X设置为-X(简单理解就是将始振动信号X沿着横坐标进行翻转),若不优于,则将初始振动信号X设置为X,即不需进行校准。如此,校准马达(即马达单体)在校准后的振动信号下振动,能提高马达单体的振动触觉反馈。
在本实施中,检测值为0.1,其检测值的负值为-0.1,从图2的映射关系中可以看出-0.1所对应的振动效果参数要小于0.1所对应的振动效果参数。需要说明的是,图2中该振动效果参数为体现马达振动刹车效果的参数,且值越小,刹车效果越好。因此,检测值的负值所对应的振动效果参数要优于检测值所对应的振动效果参数,因此请参阅图4,需要将初始振动信号X设置为-X。校准马达在校准后的振动信号驱动下,请参阅图5,明显改善了振动拖尾情况,如此增强了振动触觉反馈。
综上所述,本实施例中先确定一校准马达的振动效果参数与其校准参数的映射关系(该校准参数为体现马达的结构参数与马达的振动位移的关系的参数),如此在初始振动信号X驱动校准马达后得到校准参数的检测值,在映射关系中判断检测值的负值所对应的振动效果参数的值是否优于检测值所对应的振动效果参数的值,若是则将初始振动信号设置为-X,若否则将初始振动信号设置为X,从而增强了校准马达的触觉反馈。如此,在马达的批量使用过程中,每一个马达单体均可以根据其结构参数对振动信号进行适应性校准,提高了马达的批量使用过程中振动反馈的一致性,增强了触觉反馈。
基于同一发明构思,本发明实施例中还提供了与上述振动信号的校准方法相对应的计算机存储介质和电子设备,由于本发明实施例中的计算机存储介质和电子设备解决问题的原理与本发明实施例1所述的振动信号的校准方法相似,因此其具体实施可以参见前述振动信号的校准方法的实施,重复之处不再赘述。
