Motor vibration control method and device and computer readable storage medium

Abstract

The invention provides a motor vibration control method and device and a computer readable storage medium. The method comprises the steps: amplifying a steady-state voltage to generate a first voltagesignal for controlling the accelerated vibration of a motor to a target vibration amplitude lower than the steady-state vibration amplitude; attenuating a starting voltage to the steady-state voltageto generate a second voltage signal for controlling the motor to vibrate from the target vibration amplitude to the steady-state vibration amplitude; generating a steady-state voltage signal used forcontrolling steady-state vibration of the motor based on the steady-state voltage with the preset duration; and finally controlling the motor to vibrate through the target voltage signal generated bythe first voltage signal, the second voltage signal and the steady-state voltage signal. Through the implementation of the invention, the steady-state voltage is amplified to be used as the excitation voltage of the motor vibration acceleration section, and then the excitation voltage is stably reduced to the steady-state voltage, so that the acceleration time of the motor vibration response in the early stage is effectively shortened, and the hysteresis feeling of the motor vibration feedback to a user is reduced.

[0003] Vibration feedback is realized based on the excitation signal to excite the motor vibration in the terminal. At present, in the related art, a steady-state voltage signal of a specific period is usually used to excite the motor to vibrate. The motor will go through an acceleration process in the early stage of the vibration response to achieve Steady-state vibration, and then continue the steady forced steady-state motion after reaching the steady-state vibration until the end of the signal period, so in this case, there is a certain buffering process in the early vibration response of the motor, which will bring greater impact to the user. The sense of lag, leading to a decline in experience satisfaction
