System Overview

Short Description of the TCAM

The TCAM (Telematics and Connectivity Antenna Module) is a vehicle intelligent antenna module for telematic and connectivity purposes.
It is designed for roof mounting, with integrated antennas protected by a shark-fin cover. It consists of a fin antenna with integrated telematics transceivers for different wireless services, as well as several interfaces to the vehicle.
A built-in backup antenna provides cellular network access in case of the main integrated antennas under the shark fin cover get damaged, e.g. during a roll- over crash scenario. The TCAM is connected to the power supply via a four-pin battery connector, and to the vehicle interfaces via a 20 pin connector and a BroadR-Reach connector.

Mechanical design

Car mounting position

• The mounting location is partly under and over the roof of the vehicle.
• The fixing cap will, after installation of the module on the vehicle, will be covered by a design cap (outer cover).

In vehicle System

The in-vehicle system consists of the following components:

• TCAM (= Multi Antenna Module)
• BUB (Backup Battery)
• OHC (Overhead Compartment) with built-in microphones
• Backup speaker
• IHU (Infotainment Head Unit)

OHC (Overhead Compartment) – by Volvo

The OHC acts as the operation panel of the system. It consists of the following:

• Volvo onCall button (Road Assistance call)
• Call status indicator LED
• Microphone
• Slot for private SIM card

BUB (Backup Battery)

The BUB serves as the emergency backup power supply for the TCAM, if the main battery is disconnected during a crash or its discharged.

DIM (Driver Information Module)

The DIM is the Volvo driver information display on the dashboard. Fault messages will be displayed there.

VGM (Vehicle Gateway Module)

The VGM from Continental handles the interconnection between TCAM, IHU and DIM.
