Abstract:
The growing amount of electronic components in vehicles requires an increasing communication load between these components and hence an increasing load on the vehicles communication buses. Both aspects entail an increasing workload for the test engineer developing and executing test cases to verify the required system behaviour in the vehicle. This article considers a way to automate and reduce the workload for in-vehicle testing by augmenting the functionality of current data loggers. The idea is to use the data logger for supporting the testing process for test drivers. The introduced implementation shows a way to verify the test cases’ execution on the fly in order to avoid finding erroneously executed test cases at a later point in time. Additionally, the presented implementation seamlessly includes the test environment for in–vehicle testing into the tool chain, which is already used on lower integration levels. This allows the test engineer to reuse test cases from the lower integration levels in vehicle tests and to compare the results from test runs on different integration levels. The paper describes two stages of the development process of the augmented datalogger and includes the first feedback collected in a case study with a prototypical implementation.
