Abstract
Provided are a system and a method for optimizing driving of an ultrasonic sensor. The system for optimizing driving of an ultrasonic sensor includes: an ultrasonic sensor unit provided on an inner bottom surface of a fuel tank for a vehicle and obtaining a time of flight (TOF) for calculating a distance from the inner bottom surface of the fuel tank to a fuel surface; and a central processing unit calculating liquid level information of the fuel tank using the TOF transferred from the ultrasonic sensor unit and controlling a driving voltage of the ultrasonic sensor unit using the liquid level information.
