Mobile Digital Key Control With Continuous Vehicle Authorization

The patent segments the authentication process into multiple independent verification stages: initial digital key authentication, continuous sensor-based monitoring (seat presence, steering wheel detection, pedal position), and periodic re-verification. This multi-layered segmentation ensures that even if one authentication layer is compromised, other layers remain to prevent unauthorized access, thereby resolving the contradiction between convenience and security.

The system implements continuous feedback loops where sensors monitor user presence and vehicle operation parameters in real-time. If discrepancies are detected (e.g., unauthorized pedal pressing, unusual driving patterns), the system immediately terminates control and alerts authorities. This real-time feedback mechanism prevents account takeover exploitation while maintaining legitimate key sharing functionality.

The patent implements preliminary verification actions before granting full vehicle control. The system pre-authenticates the user through multiple sensors (seat presence detection, steering wheel grip detection, pedal position verification) before allowing engine start or vehicle movement. This preliminary action sequence ensures that even with keyless technology, unauthorized theft attempts are prevented through layered verification.
