Automotive telematics is a satellite-based system that combines two-way communication and information technology within the vehicle. The vehicle is equipped with a satellite transceiver enabling data to be sent to and from the vehicle.
Using this system allows for: vehicle tracking, monitoring of onboard systems, messaging, travel information, entertainment, security, safety and fleet management systems which monitor information such as location, distance traveled, speed, stops and fuel usage.
A vehicle manufacturer may offer telematics as a service to its customers. The benefits of this can include: the location & immobilization of a stolen or lost vehicle, notification to emergency services after SRS deployment, engine shut down and door unlocking in the event of a severe accident, roadside assistance and remote diagnosis.
