One of the key aspects of this project was defining requirements and detailed designs for several critical functions. DDI was deeply involved in the development of Over-The-Air (OTA) vehicle updates, which allow for remote software updates to the vehicle's systems, enhancing functionality and security without the need for physical intervention. Additionally, DDI worked on vehicle provisioning, ensuring that each vehicle could be uniquely identified and authenticated within the cloud infrastructure. Vehicle security was another major focus, where DDI implemented robust security measures to protect against unauthorized access and potential cyber threats.
