Hardware-in-the-loop (HIL) and fault injection testing are widely used in automotive industry to validate hardware and software architectures as best practice and in fulfillment with international functional safety standards. Time and economical investments can constitute an obstacle to the development of effective testing systems, especially for small and medium automotive industries. This paper...
The main aim of this project was to design and construct the laboratory setup to perform testing of the ABS car systems. In this paper a realistic car brake system for a one wheel with suspension is used. Development and implementation of ABS architecture for integrated real-time, embedded control software is described. At the same time, it includes an exploratory study of ABS dynamics model, monitor...
Undesired impacts on the power system caused by electric vehicles (EVs) remain a major challenge that needs to be addressed to guarantee their safe widespread adaption. In this context, efficiently balancing power demand within power grids represents a fundamental issue of vehicle-to-grid (V2G) applications of EV. Here, existing modeling approaches cover only a limited set of features required to...
Power electronics technology demontrators for electric vehicle drivetrains are primarily designed to demonstrate the feasibility of novel technical approaches rather than for simple integration into vehicle communication networks. Documentation related to integration issues is often limited. Communication protocols are heterogeneous and tend to change frequently during the development process. Higher...
This paper describes the development of a system for autonomous vehicle testing, utilising conventional network infrastructure for communication and control; allowing simultaneous control of multiple vehicles of differing vehicle types. A basic level of autonomy is achieved through the use of an Arduino based commercial autopilot (ArduPilot), which also allows for remote vehicle control via MAVLink...
Developing algorithms and parameterizing controllers for autonomous underwater vehicles are tasks which needs excessive testing. Therefore, we developed an environment and a tool chain for these difficult and mostly expensive tasks. This tool chain consist of different steps for implementing algorithms from the idea to mission ready. These steps include rapid prototyping, simulation testing, testing...
This paper discusses a rapid prototyping environment for an application developed relative to the USDOT Vehicle Infrastructure Integration program. The primary application represents opportunities beyond traditional vehicular telematic applications by virtue of the technologies leveraged to prototype a vehicle crash detection system, as well as an emission sensor network for vehicle fleets and a vehicle...
The design of distributed embedded real-time system is a challenging task. Besides solving the control-engineering issues, one has to consider real-time scheduling, reliability and production requirements w.r.t. production cost of the electronic control unit (ECU). This has a considerable impact on the employed software design techniques. These design techniques are well known in the automotive software...
We present ??FlexVehd??, a flexible radio testbed for experimental testing of transmission and reception algorithms in vehicular environments. The main feature of our testbed is to provide maximum flexibility to researchers when conducting their experiments. FlexVehd allows the user to implement in software the signal construction at transmission and its reconstruction at reception, because it incorporates...
Many automotive companies utilise an electronic park brake (EPB) system as a replacement for the conventional manual parking brake system. This allows to reduced driver workload and also supports automatic apply/release features. This paper discusses a development of an EPB control model that comprises the high level functional software algorithms to control the operation of the remote EPB actuator...
Rapid prototyping allows for evaluation of design product in a short period of time. Designers or CEOs may perceive the size and appearance of the product by touching the automatically constructed physical objects produced through rapid prototyping. However, it is usually impossible to change its color, texture, and user interface. In this paper, we introduce 'Augmented Reality based Re-formable Mock-up',...
The following topics are discussed: Matlab for data analysis and rapid algorithm development; model based design with Simulink; scripting efficiency with Matlab/Simulink; advanced Matlab scripting; and auto-code generation for rapid prototyping.
To investigate and develop unmanned vehicle systems technologies for autonomous multiagent mission platforms, we are using an indoor multivehicle testbed called real-time indoor autonomous vehicle test environment (RAVEN) to study long-duration multivehicle missions in a controlled environment. Normally, demonstrations of multivehicle coordination and control technologies require that multiple human...
This paper presents machine learning concepts to successfully implement an intelligent agent solution to the problem of autonomous control of Personal Rapid Transit (PRT) vehicles. The PRTs can operate independently and together as a whole system. Thus, they can be considered as a system of systems. By developing a set of rules for the vehicles to follow, the various parts of a Bayesian Network (BN),...
