Model Based Design is a powerfull tool that offer the possibility of test an early concept without a physical implementation. One of the benefits is a fast way to validate a design before a real implementation, saving money and time. Model In the Loop follow as a tool to test the model and lastly validate the model. This philosophy is utilized to test different types of projects, including distributed...
NASA's Low-Density Supersonic Decelerator Project is developing and testing the next generation of supersonic aerodynamic decelerators for planetary entry. A key element of that development is the testing of full-scale articles in conditions relevant to their intended use, primarily in the tenuous Mars atmosphere. To achieve this testing, the LDSD project developed a new test architecture for the...
This paper would detail a novel and Frugal Embedded Software Development Methodology, accelerates the embedded software development for Instrument Clusters and Load Centers application. The Software modules for various features are perceived as modular and re-usable blocks. The development process is completely automated using a configurable framework. This method significantly reduces the overall...
The test method for C1 tire wet grip performance based on European ECE R117 is analyzed, combined with the characteristics of China domestic proving ground, the test and evaluation process and test ability for C1 tire wet grip performance has already been established, which has great reference significance for the formulation standard for the test evaluation and classification of tire performance.
Software engineering course plays an important role for overall development of new hires in corporate training. During last few years, both academia and industry turned their attention towards integrating soft-skills in learning, while efforts are being made to bridge the knowledge, skill gap between industry requirements and what academic institutes churn out. Learners appreciate the concepts when...
The remote testing methods and diagnostic modes were analyzed to meet the needs for the vehicle remote testing and diagnostic technique of vehicle maintenance enterprises. The vehicle comprehensive property remote testing and diagnostic platform established with the application of the remote virtual instrument test technique, so that the remote network testing of the system was achieved.
In accordance with the calibration requirements of special vehicle, an automatic calibration system is developed based on PXI bus and GPIB bus. Based on bus technologies, this common calibration platform realizes the result that one platform with a variety of calibration function. The hardware of calibration system is designed based on the measurement requirements. The corresponding software system...
Precisely positioning of the dummy is the necessarily guarantee of the accuracy of testing data in real vehicle collision test. This paper discussed the deficiency of the international general dummy positioning method by using portable FARO three-dimensional coordinate instrument and then developed the portable two-dimensional positioning device. This device can provide an accurate and easy way to...
The torsional vibration of the engine is the important factor which leads to noise and has impact on the ride comfort and stability of the vehicle. In the 21st century, under the theme of energy-saving, environmental protection and noise reduction, people pay more attention to diesel engine with the strict requirements increasingly. On the basis of discussing the mechanism of torsional vibration and...
This paper discusses the results of an application of a formally based verification technique, called Instrumentation-Based Verification (IBV), to a production automotive lighting controller. The goal of the study is to assess, from both a tools as well as a methodological perspective, the performance of IBV in an industrial setting. The insights obtained as a result of the project include a refinement...
Testability analysis and fault diagnosis strategy design are important parts of testability design. Whether designing an optimum diagnostic strategy through testability analysis directly affects the improvement of fault detection and isolation ability for systems. Firstly, in the paper, the composing principle and work flow of the armored vehicles electrical system were introduced. Aiming at the shortcoming...
The performance of military ground vehicle systems quickly degrades due to high operation tempo and extreme environments while performing in-theater service. Current maintenance methods associated with this degradation are not sufficiently optimized for cost and performance. To address this issue, the United States Army is implementing a policy of Condition Based Maintenance (CBM) and being supported...
This paper presents an advanced testing system, combining hardware-in-the-loop (HIL) and machine vision technologies, for automated design validation testing of a vehicle instrument cluster. In the system, a HIL set-up supported by model-based approaches simulates vehicle network in real-time, and provides all essential signals to the instrument cluster under test. The machine vision system with novel...
The CAN bus which has been widely used in electric vehicle control system have many characteristics such as high transmission efficiency, high reliability, good real-time feature and so on. The CANoe which is the product of German company vector is a practical and powerful tool for system design and analysis. Firstly, a design scheme of simulation and test system for vehicle body CAN bus network is...
