EB tresos ACO FOTA Handler

Over-the-air updates to your Classic AUTOSAR ECU software with EB tresos AutoCore OEM Extension (ACO) FOTA Handler.

EB tresos ACO FOTA Handler is a software component residing within the dedicated ECU, providing the mechanisms for over-the-air software updates in the most customer-friendly manner possible.

Updates occur during runtime, even when the car is running or parked at any spot where mobile communication is available. ECUs execute their functionalities as usual, even while the driver goes about their daily business. The driver is only prompted to act when the system requires a confirmation of the installation or a download.


Reduce ECU unavailability

Dual banking maintains both new and old software in the ECU, providing rapid update solutions without any vehicle downtime, also simplifying quick software rollbacks in case of errors.

Reduce vehicle downtime
