METHOD AND APPARATUS FOR TESTING LINEAR PARAMETER OF VEHICLE-MOUNTED TOUCH CONTROL APPARATUS

WIPO Patent Application WO/2022/110502

A1

A method and apparatus for testing a linear parameter of a vehicle-mounted touch control apparatus. The vehicle-mounted touch control apparatus comprises a linear motor. The method comprises: according to a mechanical equation of a linear motor, an electrical equation of the linear motor, and a mechanical equation of a vehicle-mounted touch control apparatus, deriving and obtaining a voltage-to-current transfer function of the vehicle-mounted touch control apparatus (101); acquiring an initial value of a linear parameter of the vehicle-mounted touch control apparatus (102); acquiring a voltage measurement value and a current measurement value of the linear motor in a vibrating state (103); and according to the voltage measurement value, the current measurement value, the initial value of the linear parameter, and the transfer function, calculating and obtaining a target value of the linear parameter of the vehicle-mounted touch control apparatus (104). Said method can provide a haptic feedback solution that is applied to vehicles and that has relatively high accuracy.
