Problems solved by technology

In the process of inversion, there is a certain probability that the obtained input control signal start point or end point is non-zero singular change, that is, the control signal does not start from 0
The non-zero start of the excitation signal is equivalent to introducing a step signal into the signal. The current linear excitation motor (LRA) will produce an oscillating response to the step signal, which will affect the user experience.

Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] Such as figure 1 As shown, the method for generating a control signal provided by the embodiment of the present invention is applied to a motor drive system. The motor drive system includes an electronic device 1, a signal generator 2, a signal collector 3, and a motor 4. The signal generator 2 generates a drive signal. The signal collector 3 collects the driving signal to generate a relationship curve between the initial signal and time, and the electronic device 1 processes the relationship curve between the initial signal and time to drive the motor 4 to vibrate.

[0030] Such as figure 2 As shown, the electronic device provided by the embodiment of the present invention includes a processor 11 and a memory 12. A computer-readable program is stored in the memory 12. The computer-readable program is configured to be executed by the processor ...

Abstract

The invention provides a generation method of a control signal, a piece of electronic equipment and a storage medium. The method includes the following steps: acquiring a relation curve between initial signals and time, wherein the relation curve includes a number of sampling points and the time and the value of the initial signal corresponding to each sampling point; judging whether the value ofthe initial signal corresponding to a first sampling point of the relation curve is 0 or not; if the value of the initial signal corresponding to the first sampling point of the relation curve is not0, constructing an optimization function according to the relation curve; multiplying the value of the initial signal corresponding to each sampling point by a corresponding value of the optimizationfunction to get an optimization value of each sampling point; and generating a control signal according to the correspondence between optimization values and time, wherein the control signal is used to drive a motor to vibrate. The generation method of a control signal in the invention can reduce the oscillation response and improve the user experience.

Description

【Technical field】 [0001] The invention relates to the communication field, in particular to a method for generating a control signal, electronic equipment and a storage medium. 【Background technique】 [0002] For existing mobile phones, tablet computers and other electronic devices, for vibration feedback, what the experiencer feels is the intuitive physical experience brought by the work of the touch controller, and various experience feedbacks require different input signals to stimulate. In many cases, the input signal is based on the direct output of the touch controller. In order to achieve a certain vibration effect, the designer usually starts from the input end of the touch controller and reversely obtains the input control signal of the touch controller. However, there is a certain probability in the process of inverse derivation that the obtained input control signal start point or end point is non-zero and singularly changed, that is, the control signal does not s...
