Picture this: You're driving down the highway, cruising in a car packed with cutting-edge technology that seamlessly connects you to the world. 

Your vehicle isn't just a mode of transportation; it's a data hub, a guardian of safety, and a harbinger of the future.

Welcome to the world of Automotive Telematics, a realm where innovation knows no bounds.

In 2023, the telematics market was valued at a staggering USD 85.23 billion, and it shows no signs of slowing down.

With a projected CAGR of over ~17%, it's poised to soar to a mind-boggling USD 334.84 billion by 2032. Buckle up as we take you on a journey through the ever-changing paradigm of Automotive Telematics.

This shift is a result of telematics penetrating passenger vehicles, commercial vehicles, off-highway vehicles, two wheelers, bicycles.

In addition to traditional emergency services, Telematics devices inside vehicles now serve as the digital nerve center, commonly known as the Data Gateway.

Forward-thinking OEMs have turned the telematics game on its head by introducing cutting-edge features. Your vehicle can now turn into a digital fortress, thanks to telematics.

Software Defined Vehicle (SDV) is another game changing concept that enables the vehicle software to keep updating periodically and provides users the best experience, performance and prevents possible security vulnerabilities.

Telematics services as backbone of Data Gateway with high speed 5G connectivity makes SDV a reality.

Key Telematics applications and Use Cases

Let’s look at some of the key use cases for Telematics applications involving specific entities in the eco system:

Beyond these use cases, vehicle diagnostics emerge as the unsung heroes, tirelessly warding off potential hazards and glitches.

Think of it as your car's personal health tracker. Telematics services for remote diagnostics and predictive maintenance provide important insights directly to the user through a smartphone app.

Telematics Ecosystem

Want to understand Telematics Ecosystem and role played by different players? Here’s your visual cue:

1. Telematics cloud infrastructure collects data from vehicles.
2. Implements use-cases for fleet, personal car, trucks, and more.
3. Data analytics plays a big role in providing useful features such as Predictive maintenance, Driving behavior and insurance, vehicle fleet planning, and such.
4. Cloud infrastructure also plays an important role for providing emergency responses, near real time vehicle tracking.

1. TCU is connected to vehicle network over CAN and communicates externally using Mobile Network Operator (MNO) network.
2. Multiple connectivity with external world – Mobile Network, WiFi, Ethernet, and Bluetooth.
3. Implements in-vehicle use cases such as voice call, information collection, notification to cloud, Remote SW update for in-vehicle ECUs, and more.
4. TCU provides Wi-Fi hotspot inside vehicle for user device connectivity.
5. Helps to implement sensor\camera-based use-cases for driver\passenger safety. 

New Technologies Driving Changes in Telematics Architecture

With the adoption of new technologies, changing vehicle architecture with Electric Vehicles and making vehicle always up-to-date with SW Update Over the Air (FOTA\SOTA\OTA), pushes changes in the Telematics Architecture:

OTA, Enhanced Security

1. Secure communication channels and encrypted data payloads.
2. Secure storage for storing certificates and keys.
3. HW and SW assisted encryption and decryption algorithms.
4. Secure OTA update with secured private cloud infrastructure.

Multi-Connectivity

1. WAN Connectivity through 5G/LTE- includes dual sim capabilities with DSDA (Dual Sim Dual Active).
2. Wi-Fi Connectivity – May involve multiple modules for inside car and external car connectivity.
3. Bluetooth and BLE connectivity for tethering and remote operations.
4. GPS/GNSS based location tracking with assisted precision location and multi-band support.
5. Co-existence of multiple technologies.

V2X

1. Peer-to-Peer communication protocol between vehicles and roadside infrastructures.
2. Support of one or more V2X Technologies.
3. Handling safety messages.
4. Sensor fusion with Radars/Lidars.
5. ITS Stack Integration with Security protocols.

Application Framework

1. TCU’s have several distributed applications across different end use cases.
2. Need a framework to allow applications to interact with services and other applications beyond vehicle and OEM Cloud.
3. Complex Software Update Framework (FOTA\SOTA) opens the path for Software Defined Vehicle (SDV).
