The role of a cloud-based server in service workshops

Usage of cloud technology is essential for aftersales tester providers. It eases the rollout of new tester content - for example, diagnostic data of new vehicle types, updated repair manuals or ECU software for flash programming. Cloud technology also implements security services such as user authentication information.

Figure 1 shows a typical setup as it is implemented for the service of vehicles such as trucks and buses. The vehicle is parked (vehicle speed = zero) in the service workshop, and its E/E system is connected to the vehicle communication interface (VCI) via CAN or Ethernet. On the tester (TST) side, the TST-to-VCI connection is either USB or WiFi.
