Display device calibrating and/or correcting method for vehicle, involves calculating correction value according to differences between displayed values and values to be displayed, where correction value corresponds to sinusoidal function

摘要

The method involves measuring a first difference between a first value displayed by a needle (20) and a first value to be displayed by the needle. A second difference between a second value displayed by the needle and a second value to be displayed by the needle is measured. A third difference between a third value displayed by the needle and a third value to be displayed by the needle is measured. A correction value (50) is calculated according to the first, second and third differences, where the correction value corresponds to a sinusoidal function.
