The car ride is important to use performance affecting the performance of a wide variety of used vehicles. Suspension is an important part of the automobile, suspension ride on vehicles which have had a significant impact. With the rapid development of the automotive industry, how to improve vehicle ride, has become one of the designers are very concerned about the problem. In addition, dynamic analysis...
The amount of automotive software functions is continuously growing. With their interactions and dependencies increasing, the diagnosis' task of differencing between symptoms indicating a fault, the fault cause itself and uncorrelated data gets enormously difficult and complex. For instance, up to 40% of automotive software functions are contributable to diagnostic functions, resulting in approximately...
In the automotive industry an integrated set of manufacturing engineering activities lie on the critical path of the Vehicle Development Process (VDP). After the product integration design is finalized, the Production Tool Design and Build (PTDB) processes becomes the VDP critical path. It is in the PTDB where virtual launch and validation activities are performed. To increase throughput of the engineering...
This paper presents Hardware-in loop (HIL) testing for GM two-mode hybrid. First Modeling and simulation of GM two-mode hybrid using model based design (MBD) process is performed. HIL testing is performed using dSpace MicroAutoBox (MABX) and National Instruments PXI. The control strategy compiled code is uploaded to MABX using ControlDesk software and the corresponding plant model is transferred to...
We present a novel design of a source code generator for distributed automotive systems in this paper. The expanding functional complexity leads to an increase in software embedded defects and several problems. Clearly, software development methods will need to innovate. The AUTOSAR architecture has served as a platform for vehicle applications in leading OEMs and Tier1 suppliers. The standard provides...
Flex fuel vehicles can be powered by any mix whatsoever of gasoline and ethanol. Special software for fuel identification and motor control is its main feature. Beginning in 2003, today already 23% of the Brazilian fleet and 95% of new cars have been built using this technology. Bosch was the pioneer in an early version in USA, in which it has been investing since the 80s. Bosch also made the earliest...
Currently, many countries have developed new legislations which are aimed at greater emphasis to force motor vehicle manufacturers to recycle their products at the end of their life. However, before end-of-life vehicles can be recycled, the end-of-life disassembly needs to be in placed. It entails large amounts of capital expenditure and time. Most manufacturers would not like to even considering...
It is proposed a new approach based on a methodology, assisted by a tool, to create new products in the automobile industry based on previous defined processes and experiences inspired on a set of best practices or principles: it is based on high-level models or specifications; it is component-based architecture centric; it is based on generative programming techniques. This approach follows in essence...
The automotive industry is, like several other domains, a source of both challenging problems and innovative technologies of various kinds. One interesting phenomenon in this domain is the extensive interdependencies between the constituent nodes, or ECUs, of its networked embedded system. This in turn leads to extensive interactions between ECUs over the network infrastructure of an automobile.
This paper based on various vehicle model structure components, introduce on the general flow of structure topology optimization design, and reported on the latest application and innovation of the related representative software, including the development of CAE integrity software system. Overview on the innovation of application research of components property optimization and reduction of body...
In this paper, we propose a novel approach to an AUTOSAR-based tool for the vehicular applications. The embedded software in vehicles is recently required to manage complex functionalities. To address this challenge, a new paradigm has emerged in the automotive industry. Similarly, an AUTOSAR project was established by leading manufacturers and suppliers. This supports a distributed development process...
Spiraling vehicle complexity requires an overall architectural concept that provides a total vehicle perspective across all functional domains. Here we summarize the concept and some basic elements of an architecture framework for the automotive industry. We intend to drive the thought process within the automotive industry toward a standardized architectural foundation that builds upon successful...
The amount of electronics in vehicles is growing quickly, thus systems are becoming increasingly complex which makes the engineering of these software intensive systems more and more difficult. In the automotive industry the use of product line architectures enables a set of vehicles to share architecture to decrease cost and increase quality. In this study we investigate key issues related to real-world...
In automotive software and system design, explicit system and especially software models have found their way into the development process. This paper try to give an overview for what such models have so-far been used and which advantages they brought to vehicle manufacturers and suppliers. Another focus of this paper is the comparison to functional models which are already used in the automotive...
