The following specification particularly_.describes the invention and the manner in’which it is to
operate
Development of a Telematic control unit for capturing vital data of a vehicle
without using company fitted telemetry data port.
Field of Invention:
In older model vehicles, the absence or limited sophistication of Telematics Control Units (TCUS)
poses challenges in accessing real-time vehicle data. Vehicle owners often lack direct access to
detailed information stored within TCUs, which is typically restricted by manufacturers or authorized
service centers. This lack of access frustrates owners, preventing them from independently monitoring
or diagnosing their vehicle's status or performance. As a result, they rely heavily on manufacturers or
service centers for insights into vehicle diagnostics and performance, highlighting the need for
solutions enabling independent vehicle monitoring and diagnostics.The solution involves developing a
Telem'atic Control Unit (TCU) capable of gathering data from vehicle ’sensors via the Controller Area
Network (CAN) protocol. This TCU communicates directly with the Electronic Control Unit (ECU),
extracting engine performance, fuel consumption, speed, location, and diagnostic information.
Leveraging HTTPS encryption and OAuth 2.0, the TCU securely transmits data to cloud servers for
analysis. The analyzed data is then presented on a user-friendly dashboard, empowering vehicle
owners and fleet managers to optimize performance, reduce costs, and enhance safety:
Background of the invention and the prior art
The invention aims to provide an efficient and secure method for vehicle data monitoring and
analysis through a Telematic Control Unit (TCU). In the contemporary landscape, the reliance on
vehicle telemetry data for fleet management and optimization is evident. However, traditional methods
often depend on limited access to manufacturer-provided diagnostics, leading to challenges if
real-time monitoring .and proactive maintenance. The proposed TCU solution addresses these
‘
limitations by interfacing with the Electronic Control Unit (ECU) via the Controller Area Network
(CAN) protocol, enabling comprehensive data capture regardless of telemetry port accessibility. This
invention revolutionizes fleet management by offering enhanced insights into engine performance,
fuel consumption, speed, location, and diagnostics, thereby empowering vehicle owners and fleet
managers to optimize operational efficiency and ensure regulatory compliance.

Detailed description of the Invention:
In certain scenarios, there is a need for the development of a Telematic Control Unit (TCU) capable of
capturing vital vehicle data independently of the company-fitted telemetry data port. Vehicles may
encounter situations where access _to the telemetry data port is limited due to manufacturer-imposed
restrictions or the absence of such a port altogether. This limitation poses challenges in gathering
crucial vehicle information necessary for monitoring engine performance, fuel consumption, speed,
location, and diagnostic data.
To overcome the problem of limited access to vehicle data, we design a Telematic Control Unit that
collects data from the Electronic Control Unit (ECU) using the Controller Area Network (CAN)
protocol. The TCU securely transmits the data using HTTPS encryption t9 a cloud sewer for analysis.
OAuth 2.0 ensures authentication and access control. A user-friendly dashboard provides vehicle
owners with insights and control over their vehicles. The TCU helps optimize fuel efficiency and
reduce operational costs for fleet managers. However, compatibility issues between the TCU and ECU
could hinder data collection and render the system ineffective.
The Electronic Control Unit (ECU) is a device that controls and manages various functions and
systems within the vehicle. The ECU receives information from sensors placed throughout the
vehicle, such as the engine, brakes, and transmission. It then uses this information to make decisions
and send commands to different components, ensuring that everything works together smoothly. The
ECU can monitor the engine performance, fuel consumption, speed, location and diagnostic
information. ECU is responsible for coordinating and controlling the different parts‘of a vehicle to
ensure it runs efficiently and safely.
TCU is a part of a vehicle's electronic system that manages and controls the transmission of vehicle
information wirelessly to the flqet managers. The TCU is connectgd to ECU using CAN protocol . It
- enables the TCU to gather information about engine performance, fuel consumption, speed, location,
payload, and diagnosfic information. TCU plays a vital role in optimizing vehicle_ performance,
providing valuable insights to vehicle owners, fleet managers, and service providers.
To ensure the secure transmission of the collected data, the HTTPS (Hype ext Transfer Protocol
Secure) protocol is used. HTTPS encrypts the data before transmission, provider a secure channel for
the information to travel to the cloud. This encryption ensures that the data remains confidential and
protected from unauthorized access or tampering during its journey‘ Once the data reaches the cloud
server, it is decrypted, allowing for secure processing and storage. The cloud server can then analyze
the data and provide valuable information to vehicle owners, fleet managers, or service providers. In
addition to secure transmission 'and authentication, OAuth 2.0 can be implemented as an
industry-stand protocol. It allows vehicle owners to grant limited access to their data to authorized
applications or services, ensuring that only trusted entities can access and interact with the
information.
A dashboard has been created to enable vehicle owners to access and interact with this information in
a user-friendly manner. The process of transmitting raw data from the TCU into the dashboard
involves analyzing the needs of the users and designing a structured presentation of the collected data.
A performance meter or graph showing the engine‘s efficiency by analyzing the Oxygen level released
from ECU. The fuel data received from ECU and the kilometers need to be covered, will be
represented by a graphical representation for monitoring fuel needs and efficiency. A graph that
displays payload data by analyzing the payload weight the vehicle carries, if it is more than the ‘
threshold weight, an alert will be sent to the respective owner about the overload of Weight. A
speedometer-like visualization indicates the vehicle‘s speed and sends alerts if the speed is more than (Title

the threshold value. An interactive map that showcases the vehicle's current location and speed by
collecting the data from ECU emitted by GPS ‘0 prevent the vehicle from being stolen. Various metrics
or scores indicating driver behavior, such as steering mgle and braking habits to ensure the safety of
the driver. Our dashboard provides a comprehensive view of all the collected data. Fleet managers can
monitor and access the information through the dashboard. The dashboard acts as a centralized hub,
for vehicle owners with valuable insights and control over their vehicle.
One significant use case for the Telematic Control Unit (TCU) is by capturing and analyzing data such
as fuel consumption, engine performance,speed , location and driver behavior, the TCU enables fleet
managers to identify problems and implement strategies to improve economy. By optimizing these
parameters, fleet managers can minimize environmental impact, and enhance overall efficiency.
One potential Showstopper could be the lack of compatibility between the Telematric Control Unit and
Electronic Control Unit of the TCU is unable to establish a reliable connection with the ECUor if the
ECU does not support the necessary protocols for data collection, it would delay the TCU's ability in
capture essential vehicle data. This compatibility issue could prevent the TCU from functioning as
intended and collecting the required information, rendering the entire system ineffective.
