Evaluating the applicability of hardware trust anchors for automotive applications

The automotive trend towards autonomous driving and advanced connected services increases both complexity of the vehicle internal network and the connections to its environment. This introduced complexity further broadens the vehicle cyberattack surface.As mitigation strategy, state-of-the-art security mechanisms utilize so-called hardware trust anchors (HTAs) to protect security-sensitive data and processes in shielded locations that are isolated utilizing hardware security mechanisms. However, there is a variety of different HTAs with different functionality and security guarantees and there is currently no work done that compares and evaluates them against current and emerging automotive requirements.In this work, we evaluate the applicability of various HTAs to secure modern as well as upcoming future automotive applications. For this, we analyze and evaluate HTAs that are already established in the automotive field as well as promising HTAs from other domains. We extend our preliminary work (Plappert et al., 2022b) by increasing the range of the analyzed HTAs with solutions that are feasible for the most resource constrained automotive controllers and technologies that become feasible to be utilized by the introduction of high-performance controllers in future automotive architectures. We assess the different HTAs based on the evaluation criteria and in accordance to automotive requirements.

Among teenagers, the case of illegal racing is a phenomenon that often occurs. Illegal racing is an activity to compete with speed either by motorbike or by car which is carried out on public streets. The perpetrators of illegal racing are usually teenagers. They have a reason because of the lack of a place to channel their hobbies. So, they prefer to do it on the highway. Since the advent of the automotive trend among teenagers, many teenagers prefer to keep themselves busy with automotive hobbies, especially motorcycles, rather than doing brawls that are detrimental to society. But this hobby is also often misused. For example, for teenagers who have a hobby of drag racing, they often use public roads to carry out racing actions. In fact, there are also many teenagers with similar hobbies who use official racing arenas or what are commonly called circuits to channel their drag racing hobbies.

Analysis of transient phenomena in automotive vehicle suspension dampers

An automotive damper is a mature technology in the industry. From an engineering standpoint, the device design is a compromise between handling characteristics of a car, passenger comfort and safety, NVH and durability. Recently, new automotive trends in vehicle chassis design have generated research and engineering efforts. The engine and powertrain vibration reduction, the entry of hybrid/electric vehicles have caused all vibration sources due to vehicle chassis operation recognizable by both driver and passengers. Moreover, due to the increasing structural stiffness requirements imposed by vehicle OEMs (Original Vehicle Manufacturer) the energy dissipation efficiency of the damper has become a research and engineering challenge. It is, therefore, vital to propose means for eliminating or reducing their influence through changes that will result in vibration level reduction and techniques methods, metrics for evaluating them. In the dampers any disturbances in force generation translate into the device’s internal pressure fluctuations, and then piston rod vibrations transmitted to the body of the vehicle. It has been identified the pressure fluctuations are due to the valves’ inadequate performance. The dynamic effect known as rattling is detrimental to the passenger’s comfort. The phenomena have unique noise/vibration characteristics which can be related to the valves’ operation within the frequency range usually from 200 to 600 Hz. In the paper the authors investigate the opportunities for identifying the transient phenomena characteristics using a time and frequency domain signal processing technique – Short Time Fourier Transform. They examine a number of damper configurations, test them, and then apply the technique for the purpose of analysing related symptoms. Finally, they draw conclusions.

Numerical study of flow control strategies for a simplified square back ground vehicle

Current automotive trends lead to vertical shapes in the region of the rear tailgates, which induce high aerodynamical losses at the rear wall of vehicles. It is therefore important to work on turbulent wake in order to find drag reduction solutions for the current vehicle design. This paper focuses on flow control strategies, which are designed to interact with shear layers backward from the detachment region, in order to increase pressure values in the wake of a square back bluff body. This study involves large eddy simulation results validated by experimental data. After the first section, which represents experimental validation of LES computations with and without active flow control on an Ahmed bluff body, we will present a wide range of numerical results describing several active and passive flow control solutions leading to drag reductions of up to 10%. The last part of this paper will focus on some fluid mechanisms, which could explain these aerodynamical performances.

The Key Activities of Green Logistics Management in the Thai Automotive Industry

INTRODUCTION:In the early of the 21st century, environmental concept was considered as the priority of international standards and regulations in order to manage company and industr y with integration of envir onmental ma nagement in their business processes. In business process of most countrie s, the concept of Supply Chain Management (SCM) is the important strategic of all industries (Hsu, Choon & Laosirihongthong, 2014; Isaksson & Brodin, 2013; Styles, Schoenberger & Galvez-Martos, 2012a; Styles, Schoenberger & Galvez -Martos, 2012b). SCM is the integration of logistics activities and management of product, service and information that flows from first suppliers to end users and organizing the cooperation of the three main SCM dimensions; i.e. Economic, Social and Environment dimensions (Bernon & Mena, 2013; Fayezi, O'Loughlin & Zutshi, 2012).The goal of SCM is to minimize the total cost and adding value to the supply chain that uses a variety of natural resources and energy while causing minimal waste and pollution to the community and environ ment (Bak & Boulocher-Passet, 2013; Department of Primary Industries and Mines, 2011; Lorentz, Toyli, Solakivi & Ojala, 2013). T hen, this development produces pollution t hat affects the environment and communities which ar e solved by Sustainable Supply Chain Management (SSCM) (United Nation Environment Programme, 2014). SSCM is considered to be important as it is green logistics management, the management of logistics activities while considering the environmental concept , in parallel with decr ease in the envir onmental effects (Dey, Guardia & Srinivasan, 2011; Xia & Tang, 2011).In the industry manner, the knowledge of green logistics management is important for studying key activities of this management. Also, this knowledge is the key information for com panies to start green logistics management within their business processes. Furthermore, this information supports fundamental knowledge to plan the logistics management towards a company operating with environmental concept.
