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...
Data acquisition systems used as Internet of Things (IoT) devices are generally developed for applications such as renewable energy, vehicles, or biological data collection. Methodology adapted from IoT can be used in numerous applications including sensors for underwater vehicles. Autonomous Underwater Vehicles (AUV) have become more prevalent for military use. Coincidentally, modular sensor attachments...
Current education institutions lack adequate tools for teaching software programming for automotive area, especially In-Vehicle Infotainment (IVI), with available tools constrained to a palette of proprietary, closed solutions. In this paper we give an overview of a pilot In-Vehicle Infotainment Learning platform (PIVILP), based on open source technologies and achievable in any educational environment...
The increasing demand of new functionalities in next generation vehicles, leads to a growth of the complexity level for the E/E automotive systems. On the same way, the automotive software also tends to follow the same pace, so new methods should be adopted to deal with this scenario of complexity. The next generation of automotive embedded software is rapidly migrating to the AUTOSAR standard, which...
The article describes the architecture and use cases of the vehicles external control unit (BBCU — BODY & BOARD CONTROL UNIT) for the vehicle communication within global traffic systems including traffic security and safety (Car2Car, Car2Infrastructure concepts supported), IoT architectures as well as Smart Cities applications. The BBCU is an embedded system optionally supplemented with graphical...
This paper describes the implementation of a low-cost Autonomous Surface Vehicle (ASV) using a behavior-based software, the MOOS-IvP. The platform used is a catamaran boat driven by two direct current motors as the propulsion system. It is embedded with a processing board with an Arduino microcontroller, a low-cost Inertial Measurement Unit (IMU) with accelerometers, gyroscopes and magnetometers,...
This paper presents a conceptual design and field test validation of a network of surface nodes providing a communication bridge between underwater sensors and Unmanned Vehicles (UV). Here we describe the combined operations of custom made low-cost buoys and Unmanned Aerial Vehicles (UAV), linked together within one network. Buoys equipped with an underwater acoustic telemetry receiver and water parameter...
Fault protection as a discipline involves a collection of flight software logic and operational processes for detecting unacceptable anomalous behavior, responding prior to reaching criticality, restricting the propagation of a failure beyond a fault containment region, and recovering the vehicle back to full or degraded functionality if possible. The System Fault Protection (SFP) design for the SMAP...
Advanced driver assistance systems (ADAS) are designed to increase driver's situational awareness and road safety by providing essential information, warning and automatic intervention to reduce the possibility/severity of an accident. Of the various types of ADAS modalities available, camera based ADAS are being widely adopted for their usefulness in varied applications, overall reliability and adaptability...
A modular design for portable automatic test equipment used for on-platform diagnostics is described. The hardware and software architecture of the design are described in detail. The design comprises a core module that houses a processor and the primary instrumentation, measurement, and stimulus hardware of the test equipment. The design also includes an application module that provides platform-specific...
Angkutan Kota (angkot) is one of public transport that often used by citizen in Bandung. But, there's still a lot of citizen that use private vehicle instead of using public transportation like angkot. This is due to the services provided by public transport hasn't been satisfactory. Therefore, to improve the service of angkot, angkot's payment system should be improved by making a payment standard...
Run-off test is performed in factory for first few limited production build machines. It verifies all the machine functions possible. The Virtual Vehicle Run-off test is new approach for automation test to perform first level product verification and validation in virtual environment to produce higher quality and productivity. Virtual Vehicle Run-off test helps to perform software PV&V in short...
Electronic controller unit (ECU) used for controlling sub-systems of complex real life applications like automotive vehicles can pose several challenges. Many times one needs to plan development and testing of controller, when the end vehicle is also under development and hence not available. In such case, hardware in the loop (HIL) approach for testing such controllers emulates the external application...
This paper describes the indigenous development of CAN based low-cost cluster controller which drives the non-CAN cluster in a CAN based vehicle. The use of CAN network in vehicle is ever growing and has number of advantages which includes efficient diagnostics, low-cost and reduced wiring harness. The use of CAN network in a module expects the other interconnected modules also to be CAN based. Typical...
To provide complete vehicle information protection mechanism, this work proposes a vehicle information security system (VISS) with self-adaptation. The VISS integrates the concept of role-based access control, so that it can support multiuser access mechanism to avoid illegal modification. Further, all the access control policies for the information are realized as hardware circuits, so that the VISS...
Intelligent driver assistance systems and new infotainment innovations cause a rapidly growing demand of computing power. To satisfy that demand, the quantity of electronic control units in cars has increased dramatically. OEMs tackle that trend by consolidating software on powerful multicore hardware platforms. However, current software solutions are mostly static and designed to run on limited platforms...
Hardware-in-loop (HiL) simulation focuses on testing of Electronic Control Units (ECU) in virtual real time environment in order to scrutinize the behavior of controller under test. Use of HiL simulation in development process reduces time and cost involved in verification and validation of the ECU's development. Generally, HiL systems developed using dSPACE®, National Instruments® and other platforms...
We present a novel, deeply embedded robotics middleware and programming environment. It uses a multithreaded, publish-subscribe design pattern and provides a Unix-like software interface for micro controller applications. We improve over the state of the art in deeply embedded open source systems by providing a modular and standards-oriented platform. Our system architecture is centered around a publish-subscribe...
User experience of the vehicles’ telematics services depends on quality of bidirectional network connection between the vehicle and stationary high-performance computing system. In this case, there is a task of ensuring continuous data transmission between the vehicle and stationary computing system in the conditions of highly dynamic networks. The answer is to retrieve data about surrounding networks...
