Our Problem Management and Testing Coordination Team for BEV

What is Problem Management? It is an activity of managing the solutions of problems, or so-called Defects, that occur in a car. How we do this? In a much more convenient and interesting way than in the past years when automobiles had filar architecture.

Decoding the Car's Nervous System

We use applications and software tools to gather information that travels in the networks of a car like CAN, CAN-FD, FlexRay, LIN, Ethernet. They link several ECUs (Electronic Computing Unit) specialized on different functions that communicate with each other. It is like entering the “the nervous system” of the car, to collect the necessary information for an analysis to see what does not work correctly. It is an interesting activity that doesn’t have routine because each case is different from the other. The dynamicity of the project makes it interesting since we perform the technical analyze of the defect for finding the right department who will be in the end responsible for providing the solution, and we also track and manage the stakeholders to assure that the timeline is kept, and no errors will go further to the client. We also make sure that the test vehicles, in this way are “clean” and potential misleading errors are known and removed from early stages.

Powering Precision in Test Management for Electric Drive Systems

Our test management team is responsible for the management and coordination of both testbenches and test vehicles. Our main focus is to test both drivability and safety aspects of electric powertrains, with all of its main components. At the customer’s request, newly released software versions must be tested, and it is our responsibility to make sure the testing, both manual and automated, is done efficiently and that reliable results are delivered on time, while keeping the costs involved for the client as low as possible. Any test that might fail is carefully reviewed by our testers, making sure that it is a valid result and not caused by external factors. Any problems that may occur on either testbenches or vehicles are dealt with by our team as well, making sure that no delay is caused in the process.

Driving Innovation in EV Charging Testing

Our colleagues have the opportunity to contribute to developing the latest technology involved in our customers Battery Electric Vehicles charging. The daily routine consists of test case creation, as well as modifying or updating the already existing tests. These tests are based on a set of requirements, that are constantly being updated. Our make sure the updates are taken into account and that they are being tested within each software branch. All modified tests must then be validated either using the available vehicle prototypes or the existing testing platforms. We then analyze the traces before we can transfer the updated tests to a central database, called Octane and if possible, synchronize them for automatization. ?

Once the test reaches Octane, the latest version becomes accessible for everyone involved in the process and we link the test to the corresponding requirement from the Doors module. While performing validations we encounter defects which we thoroughly analyze, confront with the responsible person in charge of the function that we think caused the problem and then decide on whether we must raise a ticket so that the problem will be further analyzed until reaching a solution.

Among this tasks, we optimize the testing experiments used by our colleagues on site, for simulation purposes, based on their suggestions after they tried to use it, as well as every time we encounter tests where the labels were not suitable.
