To be published on 2020-04-14 by SAE International in United States
Global warming is one of the major concerning issues in the present world that happens mainly due to the pollution of the environment. US transportation section driven by gas is responsible for nearly thirty percent of all US global emissions, more than almost any other sections. It also consumes huge amount of resources that might risk for energy security and availability in future. In this scenario, an efficient operation and management of EVs in the power distribution systems is highly manifested to reduce environmental emissions and operational costs for the utilities, and provide financial benefits for the EV owners. This research assesses the integration of different level of EVs in the distribution system and observes its impacts on environmental emissions and power system operational costs. Integration of EVs can reduce the emission from two different aspects. First, by replacing the traditional combustion engine cars for providing clean and environment friendly transportation and second, through the V2G program, by providing power to the utility during peak hours and reducing the emission created by hydrocarbon dependent generators.…

In-vehicle infotainment (IVI) platforms are getting increasingly connected. Besides OEM apps and services, the next generation of IVI platforms are expected to offer third-party application integration. Under this business model, vehicular sensor and event data can be collected and shared with selected third-party apps. To this end, Google is pushing towards standardization among proprietary IVI operating systems with their Android Automotive platform which is running natively on the vehicle’s IVI platform. Unlike Android Auto’s limited functionality of display-mirroring certain smartphone apps to the IVI screen, Android Automotive will have access to the in-vehicle network (IVN) and be able to read and share various sensor data from the car with third-party apps. This increased connectivity opens new business opportunities for both the car manufacturer as well as third-party entities, but also introduces a new attack surface on the vehicle. Therefore, Android Automotive must have a secure system architecture to prevent any potential attacks that might compromise the security and privacy of the vehicle and the driver. In particular, malicious third-party entities could possibly remotely compromise a…

Virtual Co-Simulation Platform for Test and Validation of ADAS and Autonomous Driving

Hunan CRRC Times Electric Vehicle CO., LTD-Tian Zhu
Tongji University-Ke Song, Bin Wei, Zhen Song, Huan Chen
Published 2019-11-04 by SAE International in United States
Vehicles equipped with one or several functions of Advanced Driver Assistant System (ADAS) and autonomous driving (AD) technology are more mature and prevalent nowadays. Vehicles being smarter and driving being easier is an unstoppable trend. In the near future, intelligent vehicles will be mass produced and running on the road. However, before the mass-production of intelligent vehicles, a lot of experimental tests and validations need to be carried out to insure the safety and reliability of ADAS and AD technology. Although the road test of real vehicles is the most reliable and accurate test method, it cannot meet the need of rapid development of technology research due to high time and financial cost. Therefore, a high-efficient design and evaluation methodology for ADAS and AD development and test is a must. In this paper, a virtual co-simulation platform based on MATLAB/Simulink, OpenModelica and Unity 3D game engine (MOMU) is proposed. Simulink is used for vehicle control software modeling. OpenModelica simulates vehicle dynamic models written in Modelica. Unity provides visualized display of ADAS simulation and a virtual…

EGR Cooler Field Return Rate Evaluation Based on Product and Application Variation

Cummins Inc.-Billy Holland
Senior Flexonics-William M. Rixon, Ryan Collins, Brian Costello
Published 2019-04-02 by SAE International in United States
The automotive industry drives some of the most stringent product requirements to ensure long product life and customer satisfaction. To demonstrate compliance with these requirements new and more accurate evaluation methods are needed. Thermal fatigue life in EGR coolers for heavy duty diesel applications have historically been a critical focus for engine OEMs. Being able to accurately evaluate product return rates due to thermal fatigue failures gives the OEM confidence that all end users will be satisfied, and allows program management to properly make fiscal decisions. Additionally, weight and cost optimization can be conducted with greater confidence. This is accomplished by accounting for product variation and application variation in thermal fatigue life evaluations. Including these variations requires a simplified numerical method to calculate product life, as tens of thousands of samples will be run through the analysis to represent real life random variation. First, time dependent component temperatures are calculated based on engine conditions. The component temperatures are used to determine strain, which is then used to evaluate thermal fatigue life. Appling this life calculation…

Published 2019-03-19 by SAE International in United States
Blockchain as a technology has been successfully deployed in the financial industry. As the technology continues to mature, there are opportunities to use this to solve operational challenges in Aerospace. One of the common use cases is replacing paper records as a proof of compliance with a blockchain enabled distributed ledger.Commonly available open source blockchain frameworks have security ingrained in the components. However, replacing paper records with a blockchain based distributed ledger will require investigation of potential risks involved in the end to end usage of this technology for records management.The objective of this paper is to elucidate potential risks in an aviation record management workflow environment enabled by blockchain and suggest requirements to mitigate the risks.In addition requirements for Blockchain based systems will be proposed, which will guarantee minimum functional requirements like Protection of confidential informationIntegrity of the information in a recordSafeguards against unauthorized accessThe potential gaps are understood using an illustrative end to end blockchain based process along with their conceptual high level intermediate steps.

Analysis of the Effects of Modeling Depth and Parameter Uncertainties on the System Behavior of a Multifunctional High Lift Actuation System

German Aerospace Center (DLR)-Andreas Schäfer, Michael Schmid
Published 2018-10-30 by SAE International in United States
Modeling and simulation have become an important aspect of the design and development process of aircraft systems. During the design of high lift actuation systems for example, the dynamic loads in the transmission are estimated by simulation. Nevertheless huge development efforts and financial resources are still invested in physical testing. These integration and testing phases take place at a late stage in the design process. Therefore, identified malfunctions and development errors lead to undesired iterations and thus to high costs as well as to an increased development time. This issue is emphasized as system complexity is rises continuously in conjunction with an increase in the number of interconnections and functionality. Hence, early and continuous virtual testing activities on the overall system level become increasingly important. In order to establish such a process, this paper analyzes the effects of modeling depth and parameter uncertainties on the overall system behavior considering nominal operation as well as failure cases. It identifies which test cases can be performed in which development phase depending on the information required. The modeling…
