AI Technical Summary
Technical Problem
In the existing technology, the process of generating motor drive signals is inefficient and it is difficult to generate drive signals that meet the requirements, resulting in the need to improve the actual vibration feel of the motor.
Method used
The initial waveform curve is plotted based on the vibration waveform information of the motor to generate the initial waveform signal. The signal is then optimized through resampling, filtering, and displacement protection to generate the motor drive signal.
Benefits of technology
This improves signal generation efficiency, ensuring minimal difference between the actual vibration feel of the motor and the ideal feel, thus enhancing the user's tactile experience.

Abstract
The present invention provides a motor driving signal generation method and apparatus, a device, and a readable storage medium. The method comprises: drawing an initial waveform curve on the basis of vibration waveform information of a motor, and generating a first waveform signal corresponding to the initial waveform curve, wherein the vibration waveform information is waveform information for enabling a vibration action of the motor to satisfy an ideal haptic requirement, and the waveform curve is used for representing a change relationship of the amplitude of the signal over time; resampling the first waveform signal on the basis of a preset sampling rate and a duration of the first waveform signal to obtain a second waveform signal; and performing filtering processing and displacement protection processing on the second waveform signal to obtain a motor driving signal, wherein the motor driving signal is used for driving the motor to vibrate in a target operating frequency band. In the present application, the design of a motor vibration haptic effect can be achieved by drawing a signal waveform, thereby achieving high-efficiency waveform drawing and signal generation, and thus improving the haptic experience of a user when using the motor.
