Abstract
A vehicle controller for reducing noise of a differential gear of a vehicle, the vehicle including: a ring gear teeth-engaged with a motor reducer, a differential case connected to the ring gear, a differential assembly including a differential gear provided inside the differential case, and a disconnector device connected to at least one gear among the differential gears, the vehicle controller including: an RPM measuring unit for measuring a speed of one vehicle wheel when the vehicle is driven by two wheels; a speed calculation unit for calculating a speed of the ring gear in consideration of the speed of the one vehicle wheel; and a driving unit for driving the ring gear by controlling the motor reducer based on the speed of the ring gear.
