Abstract
A method is configured to compensate control reactivity of a shift-by-wire system in which shift ranges of an automatic transmission are changed by a motor. The method for compensating control reactivity may ensure a consistent response of the motor by including a compensation logic that measures a necessary driving time of the motor that was taken to rotate a detent plate from a current position to a target range, determines whether the motor is in an over-response state or an under-response state by comparing the measured taken time with a pre-stored setting value, accumulates an over-response or under-response detection count, performs compensation of decreasing or increasing an instruction value (a duty value) of the motor in accordance with the accumulated over-response or under-response detection count.
