Access In Vehicle Live Data

August 23, 2023
The automobile industry is embracing digital transformation at a breakneck pace. Vehicles have evolved from mere transportation to complex, data-generating machines thanks to innovations like connected cars, the Internet of Things, and advanced telematics systems. This flood of real-time vehicle data has opened up exciting new possibilities for third-party developers. There are two primary methods for accessing live vehicle data: OBD2 ports and connected car APIs.

OBD2 Ports and Dongles

OBD2 ports and dongles provide direct access to a vehicle's onboard diagnostics computer and various sensors. By connecting an OBD2 adapter, third parties can pull trouble codes and performance data in real-time. However, OBD2 has limitations - it only provides access to the engine computer and has no native security features. OBD2 is an older standard that predates modern connectivity.

In-vehicle Live Data API

In contrast, connected car APIs allow much more extensive and secure access to vehicle data. Modern vehicles contain dozens of computers and hundreds of sensors, and automakers are now exposing these systems to partners and developers through application programming interfaces (APIs). These APIs establish a direct link into a vehicle's network and allow remote access to things like location data, driver assists, battery systems, and more.

APIs provide much more granularity than OBD2. For example, a parking app could locate available spots using GPS and navigation data, while an electric vehicle charging company could monitor battery status and charging needs. APIs also enable these use cases securely with authentication, encryption, and permission systems.

Why APIs are the Way Forward

While OBD2 serves a purpose for basic vehicle diagnostics, connected car APIs are the ideal method for safely unlocking the full potential of vehicle data. As vehicles become more and more digitized, APIs provide the infrastructure to innovate and build the next generation of intelligent mobility applications.

With access to real-time data streams from sensors and computers throughout the modern vehicle, developers can create solutions not possible with OBD2 alone. As cars transform into "computers on wheels," APIs are the gateway to monetizing vehicle data and pioneering new products for drivers, businesses, and beyond. The road ahead will be paved by those leveraging connected car APIs.
