Tips: How are ultrasonic sensors used in automotive parking systems?

Ultrasonic sensors are widely used in automotive parking systems to detect surrounding obstacles during low-speed driving and parking maneuvers. Typically mounted on the front and rear bumpers, these sensors emit ultrasonic waves and receive echoes reflected from obstacles. The system calculates the distance between the vehicle and obstacles based on the time taken for the echoes to return, providing real-time feedback to the driver via audible alerts or on-screen displays. In practical applications, it primarily serves for reverse/parking distance detection with audible and visual alerts, provides critical obstacle location data for automated parking assistance systems, and identifies occupied parking spaces in smart parking lot vacancy detection. This technology offers advantages such as precise short-range detection, lower cost, and immunity to lighting conditions, making it a cost-effective solution for enhancing parking safety and convenience.
