SELF-CALIBRATING TACTILE HAPTIC MUTI-TOUCH, MULTIFUNCTION SWITCH PANEL
First Claim
1. A method for determining parameters associated with a haptic feedback output, comprising:
- detecting a vibration of at least a portion of a human-machine interface;
determining a magnitude associated with the detected vibration;
estimating a calibration offset based, at least in part, on the determined magnitude associated with the detected vibration; and
establishing at least one parameter associated with a haptic actuator of the human-machine interface based on the estimated calibration offset, the at least one parameter at least partially defining a haptic response generated by the haptic actuator.

Abstract
A method for determining parameters associated with a haptic feedback output comprises detecting a vibration of at least a portion of a human-machine interface and determining a magnitude associated with the detected vibration. A calibration offset is determined based, at least in part, on the determined magnitude associated with the detected vibration. The method further comprises establishing at least one parameter associated with a haptic actuator of the human-machine interface based on the estimated calibration offset, the at least one parameter at least partially defining a haptic response generated by the haptic actuator.
