Vehicle Safety Support With Dynamic Guide Projection for Boarding

The patent introduces a projector as an intermediary device that projects guide images on the bottom surface to indicate object locations. This mediator translates sensor data into visual information for surrounding entities, improving safety awareness without requiring direct communication between sensors and road users. The projector serves as a bridge that converts detected object positions into intuitive visual guidance.

The patent implements periodic action by updating guide images based on detected object movement rather than continuous real-time updates. The sensor identifies when an object has moved and triggers guide image updates only at these intervals. This approach maintains measurement precision by tracking object locations accurately while reducing energy consumption by avoiding unnecessary continuous updates when objects are stationary.

The patent applies universality by designing a integrated safety support system that serves multiple functions through coordinated operation of sensors, projectors, and display devices. The same sensor network that detects objects for occupant safety also provides information to surrounding vehicles through external displays. This multi-functional approach improves versatility without proportionally increasing complexity, as components serve dual purposes.

The patent implements dynamics by making the guide image location dynamic and adaptive to object movement. The projection location automatically adjusts based on real-time object position data from sensors. This dynamic tracking improves ease of operation for boarding and alighting by continuously providing accurate directional guidance. The system maintains measurement precision requirements through coordinated sensor-projection operations that update guide images as objects move.
