Abstract: The present invention relates to system and method for controlling air-pressure of tires while an in-wheel electric car is driving, using an acceleration sensor, more specifically to system and method for controlling air-pressure of each tire at real time during the driving by installing an acceleration sensor in the electric car. The method for controlling air-pressure comprises the steps of: measuring the acceleration of the driving electric car by using the acceleration sensor; calculating, by using the measured acceleration value, static normal reaction in stop state, dynamic normal reaction change generated during the driving; calculating air-pressure change in each tire during the driving, based on the calculated static normal reaction change and dynamic normal reaction change; and controlling the air-pressure of each tire by discharging or injecting the air, based on the calculated air pressure change.
