Anti-Theft Devices TRIZ Cases
- Vehicle Remote Start Torque Monitoring Security
A remote start system monitors engine torque variations to detect unauthorized vehicle movement during ignition.
- Vehicle Theft Prevention System Using Unused State Detection
A vehicle theft prevention system immobilizes the engine only after detecting an unused state through sensor signals.
- Remote Function Device Wireless Security Sensor Vehicle Bus
A remote function device uses interior and exterior wireless devices to communicate with vehicle data communications buses.
- Wireless Smart Key Face Recognition Access Control
A powerless smart key captures user face images and transmits them wirelessly to an entrance guard for identity verification.
- Vehicle Access Button Assembly with BLE Intermediary
A vehicle-mounted button assembly mediates Bluetooth Low Energy pairing between a smartphone and the car's electronic control unit.
- Electromagnetic Data Interruption Device for Vehicle Security
A data interruption device generates electromagnetic interference to inhibit communication between vehicle control units.
- Reusable Keyfob Mode Switching for Vehicle Assembly
A reusable keyfob switches vehicle modes between assembly and transportation phases at the plant.
- In-Vehicle Charger Wireless Key Interference Control
A detection unit monitors device placement to trigger communication checks that prevent electromagnetic interference with keyless entry signals.
- Door Lock Inhibition via Hood Detection
Hood detection prevents trunk key entrapment without extra sensors.
- Walking Detection Authentication System for Relay Attack Prevention
Authentication system disables vehicle control during walking detection to prevent relay attacks while maintaining operational convenience.
- Multi-Channel RKE Receiver RSSI Noise Assessment
A multi-channel remote keyless entry receiver uses an RSSI circuit to detect the preferred communication channel with the lowest noise level.
- Smart Key System Dynamic Transmission Strength Relay Attack Prevention
A smart key system adjusts response signal transmission strength based on measured noise levels to maintain communication quality.
- Vehicle Access Assembly Signal Evaluation for Secure Key Locking
A vehicle access assembly evaluates interrogation signal changes to issue control commands for locking or deactivating mobile identification transmitters.
- Capacitive Biometric Ignition Switch for Vehicle Security
A capacitive ignition switch measures driver biometrics to enable secure vehicle starting.
- Torque Estimation in Locked Adaptive Steering via Deformable Bushing
Deformable bushings preserve torque data during locked states, allowing safe unlocking after high torque events.
