Abstract

A control method for a parking release apparatus of a shift-by-wire shifting device can improve the commercial value of a vehicle by improving safety of the vehicle and preventing robbery, by interfering with or preventing an attempt of abnormally and manually releasing a parking state of the vehicle when there is no problem in the electric system of the vehicle, using a part provided to be manually operated in the parking release apparatus such that a P-stage state and an N-stage state can be manually switched when a problem, such as discharge, occurs in the electric system, in the vehicle equipped with a shift by wire apparatus.
