Automotive OTA: Software updates over the air

Delivering wireless data updates and software upgrades to vehicles

Continuously improve vehicle functions and react fast to security issues through automotive OTA updates

A connected, but not updatable vehicle is a huge cybersecurity threat. Also, consumers are used to the short innovation cycles as offered by their smartphones and computers. That is why automotive over-the-air updates are becoming the method of choice for distributing everything from infotainment system features to operating system security patches and ECU updates or configuration changes.

The task of updating critical vehicle functions places high demands on the security and reliability of the processes used for this purpose. With a software update solution in the backend and update orchestration in the vehicle, you can plan, execute, and track the status of updates for your fleet. And if an urgent update is needed, it can be initiated to keep your fleet robust and secure.
