Sonar refers to navigating and ranging sound. It has been used in cars to help drivers with their driving activities, such as parking and identifying close obstacles. The ultrasonic sensors send out quick ultrasonic impulses reflected by barriers. It then absorbs and processes the echo signals. The major components, the ultrasonic transducer, is inside the plastic case of an ultrasonic sensor. It is made of an aluminum pot with a piezoceramic portion containing a diaphragm. The sensor obtains a wireless transmission signal from the ECU, allowing the aluminum diaphragm to pulsate for around 300μsec with square waves at a resonant frequency of around 48 kHz, resulting in ultrasonic pulse emission. The diaphragm then eases for around 900μsec, in which no transmission is achievable, absorbs the reflected sound from a barrier then vibrates. The piezoceramic part emits these vibrations as analog signals, then amplifies them and transforms them into a digital signal.

Key Players
The key players operating in the global automotive ultrasonic sensors market include Texas Instruments Inc, Magna International Inc, Elmos Semiconductor AG, TE Connectivity Ltd, Baumer Holding AG, Honeywell International Inc, TDK Corp, and Autoliv Inc.
Two –four ultrasonic sensors are mounted on the rear bumper to detect an object up to 2 to 2.5 m away in the case of the rear sonar. The distance is transmitted to the driver in real-time using varying buzzer sounds. It can trace even a wire fence if it is close enough.
With regards to cars, the increasing need for ensuring safety while driving is prompting the governments of various countries to implement specific policies for the implementation of different safety features in vehicles, such as blind-spot detection (BSD). These safety features depend on ultrasonic sensors for their functioning, driving the growth of the global automotive ultrasonic sensors market.
