Title:
CALIBRATION METHOD AND DRIVING METHOD OF FORCE FEEDBACK APPARATUS, DEVICES, AND STORAGE MEDIUMS
Document Type and Number:
WIPO Patent Application WO/2023/197794
Kind Code:
A1
Abstract:
A calibration method and a driving method for a force feedback apparatus, devices, and storage mediums. The calibration method comprises: when the force feedback apparatus is not powered on, by adjusting the travel of a mover and measuring an outward output force of the force feedback apparatus, measuring a first corresponding relationship between a single body characteristic force and a travel of the force feedback apparatus (S10); when the force feedback apparatus is driven according to a preset driving mode, by adjusting the travel of the mover and measuring the outward output force of the force feedback apparatus, measuring a second corresponding relationship between an electromagnetic force and the travel of the force feedback apparatus in the preset driving mode (S20); and outputting the first corresponding relationship and the second corresponding relationship, so as to enable a force controller to determine a target driving mode according to the current travel of the mover, the target output force, the first corresponding relationship and the second corresponding relationship, and driving according to a target driving mode (S30). The method reduces the difference between the actual outward output force and the expected output force of the force feedback apparatus, thereby improving the force feedback effect.
