Background
Methodology
Based on the statistic data from OICA and NHTSA, it has been
found that the percentage of vehicles being affected because of
failures in the electronics, either software or hardware drops
gradually from almost 8% (2003) to less than 2% (2009) . However,
significant changes have taken place in 2010 and 2012, which makes
up more than 10% of the vehicle production in that year (Fig.1).
The Design and Engineering Engine (DEE) for automotive conceptual
design has been established in this research (Fig.2). The new methods and
tools that allow the designer to take electronic components, including
control software, into account already in the automotive conceptual design.
The DEE is based upon the principles of Knowledge Based Engineering
(KBE), which is essentially a combination of Computer Aided Design (CAD)
and Artificial Intelligence (AI). Moreover, the Multi-Model Generator (MMG)
which is the heart of the DEE has been developed (Fig.2). The MMG is able
to model different automobile configurations and configurations’ variants,
and provide models for multidisciplinary analysis, such as mechanics,
aerodynamics, dynamics and E/E systems as well. The MMG can establish
the relationship from the logical system architecture to the technical
system architecture and finally the software components for the E/E
systems. It can also model the logical, technical architecture and
automatically generate the source code for the software components.
The level of software integration in vehicles, such as electric cars
and aircraft, is rapidly increasing. Due to the increasing complexity
of the embedded control software, significant delays can occur in
development programs or even errors can be present in the control
software of the final product. In the development of the Electric and
Electronic system (E/E system), the analysis and specification for the
architecture of the logical system, technical system and software
itself includes many repetitive (manual) processes. Those repetitive
processes are time consuming and are prone to errors.
Aerospace Engineering
Test case --- The development of Anti-lock Braking System (ABS)
Based on a single intelligent product model, that contains the main design
parameters of the vehicle specified by the designer, two models are
generated automatically; (1) the simulation model of the physical plant
(geometric model) and the associated control system (dynamic model),
and (2) the control software (source code). The simulation model is used
to test the source code for a range of ABS maneuvers. Results show that
the source code of the control software behaves identically to the original
simulation model of the control system. The final source code is wellstructured and easy to understand due to the fact that there is a direct
relation between the vehicle design parameters specified in the original
product model and the variables and their values in the source code of the
control software. The proposed design methods and tools can in principle
be applied to any dynamic system with a high level of software integration,
such as e.g. unmanned aerial vehicles.
