Cloud technologies and digital transformation have revolutionized the automotive industry landscape. According to McKinsey, 37% of surveyed consumers indicated they would choose brands that achieve connectivity, autonomous driving, shared mobility, and electrification (CASE).

With increased demand from environmentally-conscious and tech-savvy consumers, original equipment manufacturers (OEMs) must reinvent differentiated customer experiences to gain a competitive advantage. Traditional OEMs face challenges in building automotive CASE technologies while under pressure to optimize costs and improve efficiency.

Amazon Web Services (AWS) provides the breadth and depth of purpose-built services that enable connected vehicle and mobility solutions. In a recent Frost & Sullivan Report, AWS is awarded the 2022 Company of the Year for Global Automotive Cloud Service Platform for helping OEMs build software-defined vehicle solutions by leveraging data to drive business value throughout the automotive ecosystem.

Built on AWS Connected Mobility Solution (CMS), Capgemini’s Trusted Vehicle helps OEMs bridge the gap between isolated systems, accelerate software-defined vehicle development, and create disruptive CASE technologies. Capgemini’s expertise in AWS services, Internet of Things (IoT) platforms, and automotive industry knowledge enables near real-time vehicle telemetry ingestion and processing in the cloud and at the edge.

In this post, we will show how Trusted Vehicle enables a secure and integrated vehicle-to-cloud capability for the automotive industry. Capgemini is an AWS Premier Tier Services Partner and Managed Service Provider (MSP) with a multicultural team of 350,000 people in nearly 55 countries. Capgemini has more than 12,000 AWS accreditations and over 4,900 active AWS Certifications.

Solution Architecture

The following diagram shows how Capgemini’s Trusted Vehicle connects vehicles wirelessly to CASE services such as software updates, fleet management, remote vehicle monitoring, tracking, diagnostics, and control in the cloud through cellular networks.


Figure 1 – Trusted Vehicle conceptual architecture.

In this section, we will explore Trusted Vehicle’s design approaches for connected mobility services, including:

  • Over-the-air (OTA) software updates
  • Remote vehicle services
  • Vehicle diagnostics and tracking

Over-the-Air (OTA) Software Updates

The following diagram shows how Trusted Vehicle provides customized IoT jobs based on target vehicles and fleet requirements in AWS IoT Core.


Figure 2 – Over-the-air (OTA) software updates.

These jobs are written and stored in Amazon Simple Storage Service (Amazon S3) and sent to target vehicles for execution via AWS IoT Greengrass.

Remote Vehicle Services

For remote vehicle services such as remote climate control and door lock or unlock, Trusted Vehicle enables mobile applications to send commands to MQTT topics via Amazon API Gateway and AWS Lambda.

AWS IoT Device Shadow adds shadows to make target vehicles available to mobile applications and other connected mobility services. AWS IoT Greengrass extends connected mobility services to collect and analyze data closer to target vehicles at the edge.

Vehicle Diagnostics and Tracking

Electronic control unit sends telematics data such as Diagnostics Trouble Code (DTC) and Global Positioning System (GPS) information to dedicated MQTT topics via message broker based on AWS IoT Rules configured in AWS IoT Core.

Trusted Vehicle ingests vehicle data through Amazon Kinesis Data Streams and AWS Lambda into Amazon DynamoDB and Amazon OpenSearch Service for user notification.

Solution Overview

Connecting vehicles securely to the cloud increases the speed of innovation at the edge and time to market on a global scale. Trusted Vehicle is a platform connecting vehicles, fleet managers, drivers, owners, and passengers to a mobility ecosystem, enabling safer and more reliable transportation.

In this section, let’s look at how OEMs can accelerate connected mobility solution development using Trusted Vehicle.

  1. Log in to Trusted Vehicle through Capgemini’s Digital Cloud Platform console and choose a solution blueprint such as “EV Operations.” The visual library consists of Capgemini’s view of business processes for the electric vehicle (EV) operations solution blueprint, including vehicle onboarding, telematics, value-enabled services, vehicle security, EV services, and remote Vehicle Management System (VMS).
    Each business process provides a set of APIs; for example, Telematics contains “Software OTA Update” and “Anomaly Detection.”

  1. Next, expand the selected business process, such as Telematics” Choose a business function component such as “Software OTA” update.


Figure 6 – Trusted Vehicle business functions.

  1. Business functions are exposed as pre-built REST APIs following microservice principles. For example, the “Software OTA” update function creates, deploys, and retrieves status for OTA update jobs.

  1. Repeat steps 1-3 to add more business functions. OEMs and fleet providers can develop a new connected mobility platform using pre-built APIs from Trusted Vehicle. A sample user interface of Connected Mobility Solution is shown below.

Solution Benefits

In-vehicle displays are crucial in communicating safety and warning information to the driver. However, simply relying on drivers to report issues is not ideal. Trusted Vehicle helps fleet managers proactively identify DTC to prevent unexpected vehicle malfunctions and expensive maintenance.

Besides accessibility, keyless vehicle access technology provides essential digital security that allows drivers to control their automobiles remotely. Trusted Vehicle provides secure keyless features such as remote honk, flash, lock, and unlock doors.

Each autonomous vehicle can generate up to 2 TiBs of data hourly. Finding anomalous behavior from vast petabyte-scale data streams can be challenging. Trusted Vehicle helps OEMs build anomaly detection systems to improve predictive maintenance and vehicle safety.

The rising adoption of EVs has prompted OEMs to redesign in-vehicle displays to include essential battery telemetry data such as state of health (SOH) and state of charge (SOC). Capgemini’s Trusted Vehicle allows fleet operators to perform real-time battery performance monitoring. For sustainability and cost savings, Trusted Vehicle provides fleet telematics that notifies drivers of potential overage fees for idle charging.


Developing automotive CASE technologies require:

  • Connectivity: High bandwidth communication infrastructure, such as 5G connectivity and antenna technologies.
  • Autonomous driving: Advanced sensor instrumentation, such as radar, lidar, and camera.
  • Shared mobility: Reliable and scalable applications for autonomous driving, fleet management, service subscriptions, and maintenance appointments.
  • Electrification: Batteries, powertrains, and energy storage systems.

Automotive OEMs must take advantage of mobility value propositions to deliver a personalized experience, improve operational efficiency, increase safety with predictive maintenance, and democratize data to accelerate digital transformation and innovation.

In this post, we covered how Capgemini’s Trusted Vehicle extends AWS Connected Mobility Solution and enables automotive OEMs to become mobility service providers by providing customizable blueprints and accelerators.
