ACTIVE NOISE CONTROL SYSTEM FOR VEHICLE AND METHOD OF THE SAME

摘要

PURPOSE: An active noise control system of a vehicle and a control method thereof are provided to possessively to cope with a change of an operation environment because noise is controlled by recasting active noise control logic according to a system abnormality generating state. CONSTITUTION: An active noise control system of a vehicle comprises a noise detecting part(10), a vehicle speed detecting part(20), a reverse phase sound wave output part(40), and a noise controller(30). The noise detecting part outputs noise signals by sensing noise of an indoor of a vehicle using an error microphone(12). The vehicle speed detecting part senses a vehicle speed or revolution per minute. The reverse phase sound wave output part outputs the reverse phase sound waves using a speaker. The noise controller performs an active noise control by controlling the reverse phase sound wave output part according to output signals of the vehicle speed detecting part and the noise signals. The noise controller performs the active noise control by recasting active noise control logic to make the active noise control using only the normal error microphone and speaker possible when an abnormality is generated in the error microphone or speaker.
