SafeZone is the first AI-powered vision system designed to enhance bus door safety. Using one camera module, one ECU, and high-precision vision AI algorithms, it accurately detects passengers and belongings to prevent injuries. SafeZone overcomes the blind spots and limitations of pneumatic anti-pinch mechanisms, providing a wide detection range of 30 × 200 cm. Leveraging vision AI and deep learning, SafeZone detects passengers and belongings at bus doors in real time. It proactively activates a protective mechanism to prevent doors from closing prematurely while passengers are still boarding or alighting, avoiding incidents such as clothing, backpacks, limbs being caught. SafeZone can be applied not only to buses but also to cranes, forklifts, garbage trucks, and other equipment at risk of pinching personnel. Its high level of integration makes SafeZone more than an anti-pinch system, it serves as a core safety module for smart vehicle upgrades across diverse industrial applications.
