Temperature sensors are widely used in different industrial and scientific applications. These sensors commercially available in various type and configurations allow the enhancement of automotive systems. The manufactures need to improve and upgrade the technology by research activities regarding the accuracy of temperature measuring using sensors. In this paper will analyze the trends, applications and technologies in automotive temperature sensors. PTC/NTC thermistors are measured and characteristics curves are determined as expression of mathematical functions.

The analysis of the nonlinearity of the transfer function of primary temperature transducers based on transistor structures has been performed. It’s shown that the quadratic component of the transfer function creates a significant nonlinearity error up to 0,2-0,6°C. We have developed methods of linearization based on both the formation of compensatory measuring current and change of the conversion factor of the output scaling amplifier at certain ranges of temperature measurement, which ensure their use in precision temperature measuring devices. The measurement error does not exceed 0.01°C in the range of 30-100°C.

This research paper shows a framework to conduct an empirical study in Malaysian automotive industry in order to improve their performance. There are factors which are effective factors in improving performance of Malaysian automotive companies namely top management support, cross functional teamwork, new product development (NPD) process, NPD strategies, and market research activities. The critical success factor of NPD is playing a fundamental role in determining the performance in Malaysian automotive companies. In this research study, a framework has been developed that includes critical success factors of NPD and project achievement to study their influence on the performance of Malaysian automotive companies. It is hoped that this paper can provide an academic source for both academicians and managers due to investigate the relationship between critical success factors of total NPD, project achievement and company performance in a systematic manner to increase successful rate of NPD progress.

Purpose – This paper aims to provide a European perspective on the collaborative robot business and to consider the factors governing future market development. Design/methodology/approach – Following an introduction, this first describes the collaborative robots launched recently by European manufacturers and their applications. It then discusses major European research activities and finally considers the factors stimulating the market. Findings – This article shows that collaborative robots are being commercialised by the major European robot manufacturers as well as by several smaller specialists. Although most have low payload capacities they are inexpensive and offer a number of operational benefits, making them well suited to a range of existing and emerging applications. Europe has a strong research base and several EU-funded programmes aim to stimulate collaborative robot development and use. Rapid market development is anticipated, driven in the main by applications in electronic product manufacture and assembly; new applications in the automotive industry; uses by small to medium-sized manufacturers; and companies seeking robots to support agile production methods. Originality/value – This paper provides a timely review of the rapidly developing European collaborative robot industry.

AbstractAutomotive systems are changing rapidly from purely mechanical to smart, programmable assistants. These systems react and respond to the driving environment and communicate with other subsystems for better driver support and safety. However, instead of supporting, the complexity of such systems can result in a stressful experience for the driver, adding to the workload. Hence, a poorly designed system, from a usability and user experience perspective, can lead to reduced usage or even ignorance of the provided functionalities, especially concerning Adaptive Driver Assistance Systems.In this paper, the authors propose a combined design approach for user behavior evaluation of such systems. At the core of the design is a mixed methods approach, where objective data, which is automatically collected in vehicles, is augmented with subjective data, which is gathered through in- depth interviews with end-users. The aim of the proposed methodology design is to improve current practices on user behavior evaluation, achieve a deeper understanding of driver's behavior, and improve the validity and rigor of the named results.

In the accelerated ageingtest of fuses, manual measurement was used to collect the temperature of fuse.By this testing method, the errors introduced by human were inevitable. In thispaper, an automatic temperature measuring type accelerated ageing test systemfor fuses was developed. So, the errors introduced by human were overcome.

The automotive industry is facing a tremendous growth in the engineering of software-intensive systems, giving rise to various challenges. To prevent problems related to the fit of new software technologies in vehicles and the manufacturing processes, a well functioning interaction between the functions for product development and manufacturing is crucial. This is complicated by the fact that the changeable nature of software development causes unprecedented needs for collaboration and coordination between these two functions. This paper reports on a process assessment that focuses on the interface between the functions for product development and manufacturing in the development and design of software-intensive automotive systems. The main purpose of the study was to identify the key issues for improvement in the area assessed. The assessment was performed at two Swedish automotive companies where data were collected from documents and in interviews with practitioners. Nine key improvement issues were established ranging from challenges in requirements engineering to the need for knowledge transfer between manufacturing and product development. In addition, to increase the understandability of the results and map possible avenues for solution and future research, the paper provides an extensive analysis of each improvement issue in relation to the state-of-the-art.

with the substation construction and retrofit, gradually achieve the unattended substation operation, long-term high temperature operation is the main cause of equipment wear and tear, fault, in view of the continuously monitor equipment operation temperature, helps to discover the hidden trouble of equipment operation, master the equipment running status, improve the operating life of equipment. Temperature measuring technology as the main technical means, through continuous improvement to upgrade, there are so many ways to achieve, but the lack of standards and specifications. Through the comparison and analysis of the principle of the existing equipment temperature monitoring technology, concludes the key points of equipment temperature measurement technology, discusses the development trend of substation equipment temperature measurement technology, formation of substation equipment should have the characteristics of temperature monitoring technology. In substation operations management and equipment maintenance as the goal, combined with the Internet of things, the sensing technology, the realization of intelligent substation temperature measuring technology application.
