Developing electric vehicles (EVs) has been chosen as national strategy as solution to energy security and urban air pollution by China. China has invested much to develop electric vehicle technologies. For EVs' penetration, China government develop ‘ten-city one thousand-EVs’ demonstration program in 25 cities from 2008. For mass penetration of EVs, there still exist many challenges, especially for...
The introduction of alternative powertrain technologies has brought increased design freedom in spaces within a vehicle that were previously constrained by traditional ones. Such freedom will affect the overall architecture and appearance of future alternative cars. However, these vehicles require the design, development, and integration of new specific components that are not relevant in conventional...
Mobile Money is growing in the developed world while cars are becoming much smarter. Combine the two — and you get cars that ‘own’ a wallet. We propose not a user-centric, but a car-centric service that enables cars to have Pre-Pay subscription accounts for car-related purchases and for linking to financial services. The solution uses advanced car communications capability and securely stored car...
OSEK NM (Network Management) is one of the important mechanisms to guarantee the safety of the automotive network and its working reliability has direct effect on the network communication. In order to analyze and improve the reliability, the logical ring reconstruction mechanism is improved in the scenarios of node joining and dropping out. Meanwhile the time of ring reconstruction is reduced. Through...
In automotive wiring application EM problems are often characterized by a wide span of ratio between geometrical size and signals wavelength. This is a critical situation for conventional numerical simulation tools. This paper proposes an efficient technique to overcome the difficulty of the wiring simulation on large vehicle chassis by reducing them. Using the MTL method and based on the electromagnetic...
Automotive cyber physical systems (CPSs) involve interactions between software controllers, communication networks, and physical devices. These systems are among the most complex cyber physical systems being designed by humans. However, automotive cyber physical systems are not a loose combination of cyber system and physical system, but are a tight and comprehensive integration, and they are ubiquitous...
Goal of this paper is to propose an improvement of an automotive distributed system testing process, namely the part called integration testing. The improvement is focused on test cases development, which is today done mostly manually by test engineers. The work is focused on deployment of Model-Based Testing method on field of integration testing.
The Media Oriented Systems Transport (MOST) network, the current de-facto standard for in-vehicle multimedia and infotainment, does not provide support for the stream priority and serves bandwidth allocation requests based on their arrival order, irrespective of the stream importance. This work proposes a novel bandwidth allocation approach for multimedia streams on MOST150 networks that introduces...
This paper analyzes the standardization landscape that is now taking shape to support market uptake of the electric vehicle ecosystem. For comparative qualitative analysis, data was taken from the three relevant expert assessments recently conducted by DIN, NPE and ANSI EVSP. Each of these three compendiums views a different set of standards as the basis needed for achieving market proliferation....
The majority of innovative trends in automotive industry today relies on electronic systems. Understanding the electromagnetic behavior of the electronic control units (ECUs) in a vehicle has become an ever increasing concern of automotive manufacturers. Computational Electromagnetic Modeling (CEM) is a cost effective approach that has being adopted by the automotive industry to address electromagnetic...
A significant aim in developing multimodal HCI for the automotive domain is to keep driver's distraction low. However, the measurement of the cognitive load is difficult and inaccurate but an approach to predict the effect of dialogue and presentation strategies on this is promising. In this paper we discuss cognitive load in theory and related work, and identify dialogue system components that play...
In this article, we summarized the effects incurred by IOT (Internet of Things) in automotive supply chain as follows: stimulating car demand and improving the ability of forecasting the market demand. We constructed a dual-channel automotive supply chain model composed of a car manufacturer and two car dealers from different sales channels, then under the hypothesis that the IOT is already available...
This paper proposes a new approach for predicting the Quality of Experience (QoE) of fish-eye to rectilinear transformed images used in automotive vision applications. For this purpose a dataset of automotive images was created. Subjective image quality evaluations of the dataset were carried out, in terms of visual perception and driving assistance usefulness. For objective artifact description we...
Feature-oriented software requirements specify features in a product line as separate modules. In this paper, we present the Mode-Based Behaviour pattern that provides advice on how to structure the behavioural requirements of an individual feature using state machines. The pattern not only defines the control flow of a feature, but also places constraints on the kinds of behaviour that a feature...
Magna Electronics, an automotive Tier 1 Supplier, has been actively involved in the application and production of EV and Hybrid electric drive motors, inverters, electronic, and powertrain controllers. The Ford Focus Electric vehicle program includes all of these products and stand-alone inverters for the Fisker Karma, plus assorted components for other global customers. Incorporating advanced technologies...
In this paper, we propose a pattern for decomposing and structuring the model of a feature's behavioural requirements, based on modes of operation (e.g., Active, Inactive, Failed) that are common to features in multiple domains. Interestingly, the highest-level modes of the pattern can serve as a generic behavioural interface for all features that adhere to the pattern. We have applied the pattern...
The development and test of advanced driver assistance systems (ADAS)present a challenge due to their complexity and dependency on other vehicle systems, initial conditions and their environment. Testing ADAS under real conditions leads to significant efforts and costs. Therefore, virtual prototyping and simulation are widely used instrumentsfor developing such complex systems. One of these useful...
As the design of a car is one of the most important selling criteria the antenna designer must be flexible to design antennas for cars without impeding its functionality and the aesthetics of the car. At this point the question arises, which antenna positions and what kind of radiation pattern/s would be the best in order to guarantee sufficient reception. In order to answer this question this paper...
Interference between automotive radar systems is becoming an important topic of research today, since the density of automotive radars is rising continuously. However, the total amount of cars equipped with radar is still below one percent. This paper introduces a method to predict future interference conditions between automotive radars for higher penetration rates and presents selected results.
Automotive electronics is a rapidly expanding area with an increasing number of driver assistance and infotainment devices becoming standard in new vehicles. A review of current networking standards within vehicles reveals a fragmented and proprietary situation with several standards such as MOST, CAN and LVDS dominating, all of which are currently being used by various vehicle manufacturers. Due...
