Anti-Theft Devices TRIZ Cases
- Vehicle Wireless Control Unit Interleaved Channel Transmission
A vehicle control unit transmits data packets across multiple frequency channels using interweave techniques to improve noise immunity.
- Exterior Camera Soiling Detection and Driver Alert Method
Detects exterior camera lens soiling before vehicle activation, triggering visual or acoustic alerts to ensure clean sensor views for safe driving.
- Frequency Switching Reception IC for Smart Entry and TPMS
A reception IC switches frequencies via a terminal to detect smart entry or tire pressure signals.
- Smart Key Relay Attack Detection via LF Signal Analysis
A smart key system estimates location using low frequency signal strength and direction vectors to identify unauthorized relay devices.
- Vehicle Compartment Access Control via Dynamic Lock Mechanism
Dynamic lock mechanism adjusts access scope using credentials and vehicle state to balance maintenance convenience with security against unauthorized entry.
- Steering Device Overload Clutch Protection
A press-fit clutch sleeve protects superposition gearing from overloading by separating force transmission when torque exceeds defined thresholds.
- Vehicle Access Radio Link Security Against Relay Attacks
Encrypted data connections establish dynamic frequency hopping sequences that prevent relay station attacks while reducing energy consumption.
- Vehicle Controller Authentication via Server Relay
A vehicle controller authenticates portable terminals using server relay signals to enable remote locking and unlocking operations.
- Vehicle Communication Jamming Detection via Signal Strength Monitoring
A vehicle communication system monitors signal strength indicators between the device and a known base station to detect interference.
