Data Injection and Partial ECU-simulation
Scania is one of the leading European manufacturers of heavyduty vehicles (HDV), with global sales of 66'900 trucks, 5'190 buses and 10'990 engines in 2020. Quality of the productions that Scania delivers to costumers is extremely important. That’s why we at Scania try to keep the quality and also work continuedly with improving the quality of our product.
For achieving that goal we need to introduce, design and perform different types of tests in different levels during our continues improvement. The different levels in our tests is according to the standard V-model testing. How well and reliable the verification process is done depends on quality of tests and our test equipment. That’s why improving our tests and test-systems is an important ongoing work at Scania.
In our group we develop embedded software for some ECUs and perform system and limited integration tests on the ECUs to be sure that the new functions have implemented correctly and fulfill our specification. We have regression tests that help us to check if existing functions still work properly and that adding new functions haven’t affected them.
Introducing and studying a new level of testing between the mentioned test levels (System-test and integration-test). In this new level testing, two or more real ECUs will be connected together and instead of having a fully simulated ECU and all its messages, the ECU will be active on the bus and only some of its messages should be blocked and rest of its messages will be passed to the bus. The blocked messages should be simulated by test-systems.
This approach will help us to maintain a big part behavior of that “partly-simulated” ECU and a complex model is not needed anymore during a partial simulation. Then, the test-system can take control over desirable messages selectively.
