Title:
METHOD AND APPARATUS FOR CONTROLLING OVERSTROKE OF LINEAR MOTOR, COMPUTER DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/110351
Kind Code:
A1
Abstract:
The embodiments of the present invention disclose a method for controlling overstroke of a linear motor, said method comprising: acquiring the maximum target acceleration value of the linear motor; acquiring a time domain threshold of the linear motor, the time domain threshold being the maximum acceleration of the linear motor when overstroke does not occur; when the maximum target acceleration value is greater than or equal to the time domain threshold, acquiring an excitation voltage corresponding to the time domain threshold; determining an adjustment range of the maximum input excitation voltage of the linear motor on the basis of the excitation voltage; controlling the maximum input excitation voltage to be within the adjustment range to drive the linear motor to vibrate, so as to avoid overstroke of the linear motor, thereby improving the haptic feedback effect of the linear motor, and improving the structural design efficiency. In addition, further proposed are an apparatus for controlling overstroke of a linear motor, a computer device and a storage medium.
