International Centre For Automotive Tech.-Aditi Sethi
  • Technical Paper
  • 2019-28-2464
To be published on 2019-11-21 by SAE International in United States
Authors: Aditi Sethi1, Siddhanta Shrivastava2, Madhusudan Joshi3 Organization: 1,2,3 International Centre for Automotive Technology, Manesar Introduction: With the increasing utilization of electronics in Indian automobile industry, there is an essential requirement for standardizing the functional safety of sub-systems that constitute advanced driving assistance system (ADAS) as it would be the foundation stone for the automated vehicles in future. These systems assist the driver and the driving process, further increasing the car safety and road safety, subsequently reducing human error. Due to interaction of several electronic control units (ECUs) in a vehicle and complexity of the system, electronic stability plays a vital role. Therefore, the standards shall be more performance oriented and technology neutral. They shall also cover validation tests associated with safety, mechanical rigidity, durability, environmental protection and electromagnetic compatibility. Standardization of ADAS would authenticate the quality, regulate and smoothen the uniform implementation of these sub-systems. Interestingly the standardization of ADAS is in progress at the international level. It is therefore pertinent to consider adoption, formulation or both of international standards as a part of…
 

Improved update-over-the-air solution through standardization of ‘software/firmware package format and flash jobs’

  • 2019-28-2435
To be published on 2019-11-21 by SAE International in United States
This paper investigates and proposes the possibilities of standardizing the software/firmware package format and flash jobs in order to provide the possibility of productizing the update-over-the-air solution regarding on-board vehicle components and make use of it in all OEMs with minimum configuration changes and customization. The update-over-the-air solution in the automotive sector is provided by various suppliers and needs to be customized to meet various OEMs requirements. Possible Variants of OEM requirements are: • Variant 1 o Customer Portal + Backend + vehicle on-board components solution from supplier • Variant 2 o Customer Portal + Backend solution from OEM o Vehicle on-board components from supplier • Variant 3 o Backend from OEM o Customer Portal + vehicle on-board components from supplier ODX, VBF, and many other formats from OEMs include software/firmware packages. With variant 1, these different formats are converted into one supplier proprietary format and is saved in backend and understood by the vehicle on-board components for re-programming of target ECUs. With variant 2 and variant 3, these different OEM formats have to be…

Objectives: The project goal was to create an initial set of standardized tests to explore whether they enable the ongoing evaluation of automated driving features as they evolve over time. These tests focused on situations that were representative of several daily driving scenarios as encountered by lower-level automated features, often called Advanced Driver Assistance Systems (ADAS), while looking forward to higher levels of automation as new systems are deployed. Methods: The research project initially gathered information through a review of existing literature about ADAS and current test procedures. Thereafter, a focus group of industry experts was convened for additional insights and feedback. With this background, the research team developed a series of tests designed to evaluate a variety of automated driving features in currently available implementations and anticipated future variants. Key ADAS available on current production vehicles include adaptive cruise control (ACC), lane keeping assist (LKA), and automatic emergency braking (AEB). Seven of the most automated production vehicles available in 2018 from six manufacturers were subjected to a series of standardized tests that were performed…

How Miniaturized Distributed Modular Architecture Advances Avionics Design

Aerospace & Defense Technology: August 2019

Published 2019-08-01 by SAE International in United States

Most of today's collision-avoidance, in-flight-entertainment (IFE), air-to-ground-communications, and other avionics systems employ electronics packaging based on the Aeronautics Radio INC (ARINC) 600 standard. Compared to the older ARINC 404 standard dating from the 1970s that defined “black box” enclosures and racks within aircraft, ARINC 600 specified a Modular Concept Unit (MCU) - the basic building block module for avionics. An ARINC 600 metal enclosure can hold up to 12 MCUs, allowing a lot of computing power to be placed in a centralized “box.” By making it possible to run numerous applications over a real-time network, ARINC 600 enabled “next generation” integrated modular avionics (IMA).

EMAG L.L.C. is the U.S. subsidiary of a major German machine tool builder that specializes in machine tools for the production of automotive, off-highway, agricultural, and oil field components. The company’s equipment ranges from basic round part turning centers to large-workpiece, five-axis machining centers; gear hobbing machines; and alternative equipment such as laser welding and electrochemical machining centers. This wide variety of machine tools requires an assortment of control technologies to power and manage the motion. For one customer requirement where a major agricultural equipment builder needed grinding, turning, and turn-grind machines, EMAG looked to Siemens for a standardized CNC solution.

 

Aerospace Series - Quality Management Systems - Nonconformity Data Definition and Documentation

G-14 Americas Aerospace Quality Standards Committee (AAQSC)
  • Aerospace Standard
  • AS9131D
  • Current
Published 2019-05-31 by SAE International in United States
This standard defines the common nonconformity data definition and documentation that shall be exchanged between an internal/external supplier or sub-tier supplier, and the customer when informing about a nonconformity requiring formal decision. The requirements are applicable, partly or totally, when reporting a product nonconformity to the owner or operator, as user of the end item (e.g., engine, aircraft, spacecraft, helicopter), if specified by contract. Reporting of nonconformity data, either electronically or conventionally on paper, is subject to the terms and conditions of the contract. This also includes, where applicable, data access under export control regulations.

Published 2019-04-02 by SAE International in United States
The driving behaviors of young drivers under the influence of anger are analyzed by driving simulator in this paper. A total of 12 subjects are enrolled during the experiment. Standardized videos are utilized to induce the driver's anger emotion. And the driver's electrocardiogram (ECG) signal is collected synchronously and compared before and after emotional trigger, which prove the validity of emotional trigger. Based on the result, the driver's driving performance under the straight road and the curve under normal state and angry state are compared and analyzed. The results of independent sample t-test show that there are significant differences in the running time of straight sections and the standard deviation of steering wheel angle in curves between normal and angry states. In conclusion, the longitudinal and lateral operation of drivers is unstable in angry state and the driver will be more destructive to the regular driving behavior. The results can provide theoretical basis and data support for the analysis of driving mechanism in anger.
