AN76530 - Psoc® 1 Automotive Ultrasonic Distance Measurement For Park-Assist Systems
Ultrasonic parking-assistance (UPA) systems are increasingly popular in cars because they enhance safety and driver convenience, especially in large cities. This application note shows you how to create an ultrasonic distance-measurement system using enclosed ultrasonic transducers, which are typical in automotive applications. Our implementation measures the distance between the ultrasonic transducers and any nearby objects. You can use the distance value locally within the system to control outputs or displays. You also can send the distance value, using a communication interface, to be used by another controller in the vehicle. Modern safety expectations and driver convenience, along with parking conditions and increased vehicle size, are driving the popularity of UPA systems.
