Telematics & Connected Cars
Modern vehicles are connected computers on wheels. Telematics combines GPS tracking, cellular connectivity, and vehicle data for safety services, infotainment, over-the-air updates, and autonomous driving infrastructure.
What is Telematics?
The term combines telecommunications and informatics—using GPS and cellular technology to transmit vehicle data. Modern telematics systems collect location, speed, acceleration, fuel consumption, and diagnostic data, transmitting it to cloud platforms for analysis.
Safety Services
Aftermarket and OEM telematics systems provide critical safety features:
- Automatic Crash Notification: Detects collisions and alerts emergency services with location
- Stolen Vehicle Tracking: GPS tracking to locate and recover stolen vehicles
- Roadside Assistance: One-button access to emergency services
- Curfew Alerts: Parents notified if teen driver exceeds time/location limits
- Driving Behavior Monitoring: Feedback on speed, braking, acceleration
V2X Communication
Vehicle-to-Everything (V2X) is the next frontier. Vehicles communicating with infrastructure (V2I), other vehicles (V2V), pedestrians (V2P), and networks (V2N) enables safety applications impossible with sensors alone.
DSRC vs C-V2X
Two competing technologies emerged:
- DSRC (Dedicated Short Range Communications): Based on IEEE 802.11p, operational since 2015
- C-V2X (Cellular V2X): Uses LTE/5G cellular networks, backed by 5GAA automotive consortium
Over-the-Air Updates
Tesla pioneered over-the-air (OTA) updates in automobiles, remotely fixing bugs and adding features. Traditional automakers have struggled to match this capability, but are now implementing OTA updates for everything from infotainment to drivetrain calibration.
