Reliable sensor visibility is essential for the next generation of assisted and autonomous driving. This presentation will explore a compact, low-power solution developed using ultrasonic technology that actively detects and removes obstructions from automotive camera surfaces. By combining real time diagnostics with targeted ultrasonic actions — atomization, de icing, and debris removal — the system adapts its clearing strategy to water droplets, dust, ice, snow, mud, and other contaminants.
This integrated approach ensures consistent performance, low energy consumption, and minimal reliance on external components or complex software. It supports interior and exterior camera modules, enhances driver monitoring reliability, and enables efficient protection against insects through continuous ultrasonic pulsing. The technology is lightweight, maintenance free, environmentally considerate, and easily retrofittable into existing vehicle platforms without affecting aesthetics.
Together with onsemi image sensor technology, this ultrasonic clearing solution simplifies camera module design while delivering robust obstruction detection and high efficiency clearing—key capabilities for advancing automotive safety and autonomy.
