The present disclosure provides a wiper motor control system for a vehicle, which precisely controls the speed of the wiper motor to improve the wiper performance. The present disclosure implements a wiper motor control method in a new form, which precisely controls a speed of the wiper motor for each section through a scheme of improving a plate structure of the wiper motor and monitoring a state of a parking switch, and thus reduces a noise generated in an operation of a wiper device and increases the wiping performance through a differentiated speed for each section, which generally improves the wiper performance. More specifically, the present disclosure implements a smart ECW (Electric Control Wiper) control module inputting a remote control by a wireless transmitter, so that a driver can wirelessly control a wiper before getting into a vehicle, which makes the driver feel convenience and induces the driver to safely drive.
