11.2 Telematics System
11.2.1 Overview
Telematics system is adopted for C5.
Telematics system is a coined word created from "telecommunication" and "informatics", and it indicates information,
contents service, and service provided by external source through integrating a communication system into a mobile
unit such as an automobile and the use of bidirectional communication technology.
Providing "security through connection"
A speedy support through communicating with an operator or information notification during an accident or vehicle
breakdown is realized.
Providing maintenance information which is the foundation of improving customer satisfaction
By linking with the "Care Connect", a function to notify the health condition (Health Report) and maintenance period
(oil, periodic maintenance) of the vehicle is installed.
Data Communication Module (DCM) and security measures
The data communication module is installed inside the cabin at the center of the vehicle where effect of collision is low.
Also, a structure that operates on built-in battery in the DCM if the power supply from the vehicle battery stops is
adopted to continue emergency call.
In the DCM, microcomputer connected to the antenna (external) and microcomputer for communication inside the
vehicle (CAN, etc.) are separated. Communication protocol between these two microcomputers are encrypted by the
manufactures original method. A structure that blocks intrusions from the antenna inside the DCM is adopted. Also, the
DCM will not operate even if it is installed into another vehicle.
The telecommunication method supports LTE in addition to 3G
The shark fin antenna on the roof is set as the main antenna, and the antenna in the instrument panel (behind the meters)
is set as the sub-antenna.
