Abstract
A system for a vehicle includes an ultrasonic sensor including a layer of material such that vibration of the material is indicative of frequency of transmitted and received ultrasonic signals, and a controller configured to, through electrical excitation, cause the material to vibrate to transmit an inquiry ultrasonic signal and, responsive to receiving from an object an acknowledgement ultrasonic signal having frequency different from frequency of the inquiry signal, steer the vehicle from the object.
