Abstract
A method for determining a liquid level in a tank of a vehicle uses an ultrasonic sensor for emitting and receiving ultrasonic waves. Basically the liquid level is determined based upon measuring the transition time of an ultrasonic wave emitted by the ultrasonic sensor, wherein the emitted wave is deflected two times before being reflected by the surface of the liquid contained in the tank.
