Ultrasonic distance measurements for parking-assistance systems in automotive
Parking assistance systems are becoming a common feature in modern day cars to enhance safety and driver convenience. These systems use ultrasonic transducers and a microprocessor unit to compute the distance between the surrounding objects and car’s body. This application note from Cypress describes how to build an ultrasonic distance-measurement systems and provides a reference hardware design of a four-channel ultrasonic distance measurement system for parking-assistance applications.
