Modern driver assistance systems are often using a wide range of equipped sensors as primary data source. The reliability of each sensor is specified by the manufacturer and influences the system reliability distinctly. To prevent potential fatal system failures, diverse failure prevention mechanisms are included. Nevertheless, a certain level of reliability of the system has to be guaranteed to meet...
The development of modern driver assistance systems in the automotive domain requires extensive testing, for safety as well as for legal reasons. This is especially the case for sensor-based systems that provide support for autonomous driving: if they fail, an accident may occur with fatal consequences. In the majority of cases, the required test effort is roughly estimated by means of previous project...
Software fault prediction promises to be a powerful tool in supporting test engineers upon their decision where to define testing hotspots. However, there are limitations on a cross project prediction and a lack of reports upon application to industrial software, as well as the power of metrics to represent bugs. In this paper, we present a novel analysis based upon faults discovered in model-based...
In this paper, we present a novel industry dataset on static software and change metrics for Matlab/Simulink models and their corresponding auto-generated C source code. The data set comprises data of three automotive projects developed and tested accordingly to industry standards and restrictive software development guidelines. We present some background information of the projects, the development...
In industry, embedded systems continue to become even more complex. The development is done increasingly in a virtual environment to accelerate the prototyping and the implementation. Independent from this fact, testing is still the essential activity for verification and validation and obtaining confidence in the quality and reliability of the product. The main driver behind innovation is software,...
In industry, embedded systems become complex multiple functionality devices. Research and industry have investigated the issue, how to derive test cases to cover test requirements within minimal time. For the automation of all activities related to testing tool support is available. Yet, one question is getting increasingly difficult: How to derive good, i.e. significant test cases, embracing requirements...
Embedded systems become increasingly complex and distributed. Although there is necessity for thourough testing, exhaustive validiation and verification is hardly possible in industry due to time and resource restrictions. In the past the reason for this has often been that it was to time-consuming to specify, to execute, and to evaluate test cases for the first design models and the integrated embedded...
Embedded systems in automobiles become increasingly complex as they are intended to make vehicles even more safe, comfortable, and efficient. International norms like ISO 26262 and IEC 61165 postulate methods for the development and verification of safety critical systems. These standards should ensure that the dependability and quality of the embedded systems is maintained while their complexity...
Embedded software for modern automotive and avionic systems is increasingly complex. In early design phases, even when there is still uncertainty about the feasibility of the requirements, valuable information can be gained from models that describe the expected usage and the desired system reaction. The generation of test cases from these models indicates the feasibility of the intended solution...
The development of economic and hybrid vehicles is only possible with complex systems to control the energy management and engine. The amount of embedded electronics and software to realize these systems increases continuously, and hence the complexity of the integration. The functional validation and testing of these systems is of increasing importance, as these systems have an increasing impact...
Extended Automation Method 2.0 (EXAM) is employed at AUDI AG to perform the testing of automotive systems. The main drawback of EXAM is, that each test case must be devised and created individually. This procedure is apparently awkward and error-prone. Moreover, the development of increasingly complex functionality poses new challenges to the testing routine in industry. We employed Timed Usage Models...
Model-driven testing based on Markov chain usage models (MCUM) is an established method to address testing issues. It is not possible, however, to describe by means of MCUMs the timing of stimuli and time dependencies between inputs and outputs of a system. Additional concepts and information is needed. In this paper it is presented how Timed Usage Models (TUM) can be used to solve this issue. Concepts...
