Enhancing drivers’ digital car experience with over-the-air (OTA) updates for firmware, new features and software
Head of Delivery Units Ukraine
A German manufacturer of commercial electric cars wanted to ensure that critical automotive software updates are delivered in a timely and secure manner by using over-the-air (OTA) repeats.
It is extremely important that critical updates are delivered promptly, even when Wi-Fi is not available. As a large fleet of vehicles is often located in urban areas, a solution was needed to avoid overloading cellular networks.
Tietoevry’s automotive team developed a concept of over-the-air (OTA) solution, which allows distributing software updates over a wireless network without the need for physical access to a vehicle. A manufacturer can remotely deliver firmware updates, patches, software and data updates to a vehicle removing the need for a driver to contact a dealer or a repair shop.Automotive software R&D services
A German automotive manufacturer of commercial electric cars manages a large fleet of vehicles often located in urban areas. For great driver experience and safety, automotive software update installation should not fail under any conditions, as there is no personnel to fix it.
The solution enables managing automotive software of a large fleet of cars remotely by using Wi-Fi, LTE, or 3G.
The developed algorithm guarantees authenticity, integrity and confidentiality to secure communication between vehicles and cloud.
Remote software and data updates make it easy for drivers who do not need to contact a dealer or a repair shop.
To ensure firmware installation regardless of disruptive factors, the software must be fully downloaded, the vehicle must be parked and the engine turned off. A Special Diagnosis manager is introduced as an extension to verify that the newly updated software operates as expected. It can also initiate the rollback procedure to the previous software version.
