Title:
MOTOR DRIVE SIGNAL GENERATION METHOD, ELECTRONIC DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/140587
Kind Code:
A1
Abstract:
Disclosed is a motor drive signal generation method, relating to the technical field of electronic devices and comprising: acquiring an acceleration segment signal, a constant segment signal and an attenuation segment signal (101), wherein frequencies of the constant segment signal and the attenuation segment signal are both smaller than that of the acceleration segment signal; splicing the acceleration segment signal and the constant segment signal, and reserving a silent period without signal output between an acceleration segment and a constant segment to obtain a first motor drive signal (102); adjusting a constant segment signal parameter of the first motor drive signal according to a vibration sensing requirement (103), and splicing the attenuation segment signal to a position behind the adjusted first motor drive signal to obtain a second motor drive signal (104); adjusting an attenuation segment signal parameter of the second motor drive signal to obtain a second motor drive signal with the highest braking efficiency (105); and determining the second motor drive signal with the highest braking efficiency as a final motor drive signal (106). By means of the method, a low-frequency heavy tactile effect can be achieved when the motor vibration is controlled, such that the fidelity of the specific tactile effect in scenarios, such as a game and a car central control screen, is improved.
