Combines camera-based occupant detection, temperature monitoring, and AI dialogue to warn caregivers and guide rescue for people left in vehicles.

Sensor fusion detects cargo theft around unattended autonomous vehicles, triggers onboard deterrents, and reports incidents to cloud mission control.

Risk-based control of ECU access and log transmission reduces PDP overload, prevents log loss, and preserves real-time vehicle functions.

Optical sensors built into the steering wheel capture fingerprint and pulse data for keyless driver authentication and state monitoring.

Confirmation history from a server lets work machines skip repeated precaution displays for trained operators while preserving targeted safety prompts.

Command integrity checks, entity authorization, and safe-state verification prevent unsafe or unauthorized remote vehicle actuation.

Vehicle-mounted cameras and ID checks secure trunk-based unattended sales by detecting intruders and reporting theft to authorities.

HF transceivers use time-of-flight between the door and cabin to distinguish lock and unlock gestures without false capacitive triggers.

A motor-driven locking pin with tamper sensing, GPS, and wireless alerts secures trailer landing legs against theft and bypass.

Capacitive touch sensing lets hidden vehicle door handles extend and unlock automatically while managing guard mode and motor thermal protection.

A vehicle controller uses distance sensing and portable-device motion data to open movable components without cameras or radar.

A predefined mode-selector pattern locks the vehicle in park during showroom use, preventing unintended movement while keeping auxiliaries active.

A concealed mobile-linked power switch disables motive vehicle components remotely, helping prevent theft without relying on factory security.

A management server automates deletion of linked vehicle digital keys across shareable devices, reducing manual key-by-key removal burden.

Profile-based locking manages vehicle-mounted accessories by user role and proximity, with auto-locking at speed or connectivity loss.

Lock-state feedback lets an automobile hatch set zero position correctly even from an improper position, avoiding misalignment and manual adjustment.

Selective activation of primary and secondary vehicle authentication sensors cuts standby power while preserving digital key access reliability.

A vehicle checks geofence status only when functions like charging or updates run, cutting energy use, processor load, and location data traffic.

Predefined time, location, and appointment triggers activate valet mode automatically, protecting vehicle privacy without manual authentication.

Context clustering helps a vehicle choose voice or face biometrics and update references when one modality fails.

Multi-threshold face checks combined with driving habit matching improve vehicle theft detection without sacrificing user convenience.

Verifier feedback flags invalid vehicle operation requests, then updates authentication or authorization data to block repeated unauthorized access.

Combining BLE and UWB distance measurements enables more precise device position estimation while balancing accuracy and power use.

Adjusting seatback angle to match steering wheel tilt keeps UV intensity on target and improves in-vehicle sterilization coverage.

A single Bluetooth LE link hands over across vehicle anchors to trilaterate digital key position with lower memory, bandwidth, and processing load.

Sector-based vehicle risk images highlight hazard directions and merge same-type targets into one icon for faster occupant recognition.

Multi-stage biometric checks combined with driving habit matching help balance vehicle access convenience and theft prevention.

Stored operator credentials enable work machine authentication before the management device starts, helping block unauthorized operation.

Suspension ride height and pressure signals track load changes in transit, enabling timely lost-load alerts with fewer added sensors.

Reserved secure storage for digital vehicle key data is released on demand, improving access control, space use, and low-battery data integrity.

A smartphone-linked OBD dongle downloads vehicle-specific immobilizer algorithms so users can program smartkeys and transponder keys accurately.

2D AI person detection guides selective 3D positioning to speed outdoor and industrial monitoring while reducing computing load.

A radially biased lock piece engages the steering shaft instead of the movable tube, reducing friction, abnormal noise, and wear.

After a collision, the controller unlocks the electric door and opens it slightly so occupants can pull it open manually when control is offline.

Temporal analysis of amplitude and phase changes helps radio authorization systems detect relay attacks without complex hardware.

2D AI person detection selects relevant stereo 3D data, cutting compute load while enabling real-time outdoor and industrial localization.

Multiple tilt thresholds tied to engine state prevent false anti-lift alarms during vehicle preconditioning and engine vibration.

Sensor-based loading bridge detection locks winches and height adjustment to avoid unloading interruptions and notify dispatchers.

By comparing motion sensed by the vehicle and a carried sensor, this case blocks relay-style access based on device possession alone.

Delayed audible, visual, and image capture signals help identify a hijacked vehicle without provoking immediate violence or losing track of it.

Integrated steering wheel sensors scan, verify, and store driver ID so vehicle information is available instantly during stops or emergencies.

A three-node check blocks unauthorized digital car key control requests before vehicle operations are executed, improving attack resistance.

AI on the vehicle key recognizes predefined motion patterns to open the trunk hands-free without costly bumper sensors or mud-sensitive detection.

An AR-linked vehicle key lets users locate the key and view vehicle position, status, range, and functions without adding complexity to the key.

Specific event detection powers drive-control hardware before authentication finishes, cutting vehicle startup delay while preserving security.

When a cyberattack hits an unattended vehicle, boarding guidance and terminal alerts help users decide whether to board or use alternatives.
