Thema: Systematic Derivation of Feature-driven and Risk-based Test Strategies for Automotive Applications

Abstract:

The automotive industry is currently characterized by a disruptive change in terms of

electro-mobility and highly autonomous driving. Similarly, new mobility concepts pose

particular challenges for quality assurance measures in automotive product development.

Traditional, experience-based approaches for deriving quality assurance strategies do not

address these challenges and lead to potentially high failure rates during product operation.

Therefore, a risk-based approach for the derivation of feature-specific test strategies

is proposed in this thesis, which enables the objective definition of test end criteria

and, through appropriate prioritization, an increase in the efficiency and effectiveness

of performed verification and validation activities. On the basis of a two-stage risk

assessment, quality assurance measures can initially be defined in early project phases

and then be refined for individual product features as soon as required information is

available. A framework for the derivation of test strategies is presented, which considers

the current state of the art with regard to functional safety and distinguishes the applied

acceptance thresholds for test-end criteria based on previously defined risk classes. The

presented approach is evaluated in context of series development projects, where the

significance of the risk assessment is verified through data analysis. The test strategy

applied in those projects is retrospectively evaluated and compared against the risk-based

approach presented in this thesis in terms of achieved effectiveness and efficiency. Finally,

two different concepts for measuring quality of automotive products are introduced and

profound product release criteria are defined.
