Method and device for generating motor brake signals

Abstract

An embodiment of the invention relates to the technical field of electronic equipment, and discloses a method for generating motor brake signals. The method for generating the motor brake signals includes steps of S1, controlling motors by the aid of different brake signals to obtain vibration allowance of the motors; S2, selecting brake signals with excellent performance from the various brake signals according to the vibration allowance of the motors. The vibration allowance of the motors corresponds to the various brake signals. The selected brake signals with the excellent performance areused as the motor brake signals. The performance of the corresponding brake signals is improved along with decrease of the vibration allowance of the motors. The invention further provides a device for generating the motor brake signals. The method and the device for generating the motor brake signals have the advantage that excellent brake effects can be realized by the motors.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of electronic equipment, and in particular to a method and device for generating a motor braking signal. Background technique [0002] As more and more mobile phone manufacturers launch full-screen products, consumers are beginning to pay attention to the new form of future mobile phones with full-screen phones, and the tide of full-screen phones has officially arrived. While ensuring the shocking visual effects and stunning appearance brought by the full screen, it must also have more practical features. It is an inevitable development trend that physical buttons on mobile phones are replaced by virtual buttons. The virtual button means that when the user presses a button in the button area, the mobile phone will respond with a short-term vibration that meets the vibration intensity requirements, simulating the tactile experience of the physical button feedback to the user. In order t...

AI Technical Summary

Problems solved by technology

[0003] The inventor found that there are at least the following problems in the prior art: the short signal waveform of the mobile phone’s virtual key to achieve the vibration effect has various types of changes in frequency and amplitude, and the braking achieved by using a single resonant frequency signal is inefficient in actual use. , the motor vibration cannot be stopped quickly, and if the signal amplitude is adjusted incorrectly, there will be a problem of reverse acceleration, which will cause the motor to fail to have a good braking effect
