Handleless Vehicle Door Intent Recognition for False Opening Prevention

The patent introduces an intermediary intent detection system between the key fob detection and door presenter activation. This intermediary layer analyzes additional signals (camera detection of hand movements toward door, radar detection of approach trajectory) to verify genuine opening intent before triggering the door presenter, thereby preventing false activation by pedestrians or unauthorized individuals who merely approach the vehicle

The system implements feedback mechanisms where the door controller continuously monitors multiple detection components (key fob presence, camera tracking of hand movements, radar detection of approach patterns) and adjusts door presenter activation based on the synthesized intent assessment. This feedback loop ensures that door opening is triggered only when all indicators confirm genuine user intent rather than accidental proximity

The patent segments the intent detection function into multiple independent detection components: key fob detection for authentication, camera detection for hand movement analysis, and radar detection for approach trajectory. Each component independently evaluates a specific aspect of opening intent, and their combined results provide reliable authentication that distinguishes genuine users from passersby

The door entry system integrates multiple detection functions into a unified intent recognition system. The same camera and radar systems that detect key fob presence are also used to analyze hand movements and approach patterns, creating a multi-functional detection system that reliably distinguishes between authorized users intending to open the door and others merely approaching the vehicle
