The Challenge
A German manufacturer of commercial electric cars was faced with the challenge of ensuring that critical automotive software updates are delivered in a timely and secure manner using over-the-air (OTA) updates. The importance of prompt delivery of these updates was paramount, even in situations where Wi-Fi was not available. Given that a large fleet of these vehicles is often located in urban areas, there was a need for a solution that would not overload cellular networks. The manufacturer also needed to ensure that the software update installation would not fail under any conditions, as there was no personnel available to fix it.

About The Customer
The customer is a German automotive manufacturer of commercial electric cars. They manage a large fleet of vehicles often located in urban areas. For the manufacturer, ensuring a great driver experience and safety is of utmost importance. This includes ensuring that automotive software update installations do not fail under any conditions, as there is no personnel to fix it. The manufacturer is committed to providing cost-effective software maintenance, improving vehicle security, and enhancing driver satisfaction and brand loyalty through remote software and data updates.
The Solution
Tietoevry’s automotive team developed an over-the-air (OTA) solution that allows for the distribution of software updates over a wireless network without the need for physical access to a vehicle. This solution enables the manufacturer to remotely deliver firmware updates, patches, software, and data updates to a vehicle, eliminating the need for a driver to contact a dealer or a repair shop. The solution also guarantees the authenticity, integrity, and confidentiality of communication between vehicles and the cloud. If a software update is interrupted due to any external factors, the system is designed to roll back to the previous state from the backup. The solution also includes a special diagnosis manager to verify that the newly updated software operates as expected.

Case Study
Integral Plant Maintenance
Mercedes-Benz and his partner GAZ chose Siemens to be its maintenance partner at a new engine plant in Yaroslavl, Russia. The new plant offers a capacity to manufacture diesel engines for the Russian market, for locally produced Sprinter Classic. In addition to engines for the local market, the Yaroslavl plant will also produce spare parts. Mercedes-Benz Russia and his partner needed a service partner in order to ensure the operation of these lines in a maintenance partnership arrangement. The challenges included coordinating the entire maintenance management operation, in particular inspections, corrective and predictive maintenance activities, and the optimizing spare parts management. Siemens developed a customized maintenance solution that includes all electronic and mechanical maintenance activities (Integral Plant Maintenance).
Case Study
Monitoring of Pressure Pumps in Automotive Industry
A large German/American producer of auto parts uses high-pressure pumps to deburr machined parts as a part of its production and quality check process. They decided to monitor these pumps to make sure they work properly and that they can see any indications leading to a potential failure before it affects their process.
