This document provides an overview of a connected car platform developed by Smart Driving Labs for Toyota Tsusho Corporation. The platform uses an onboard device connected to the vehicle's OBD2 port to gather real-time data on location, driving behavior, and vehicle diagnostics. This data is stored securely in the cloud and can be accessed through APIs and SDKs. Features of the platform include remote monitoring and control, over-the-air updates, usage-based insurance programs, fleet management tools, and modular integration with external systems. Several case studies demonstrate how the platform has been implemented for clients in applications like test vehicle analytics, connected car integration in vehicle manufacturing, and smart leasing programs.
