Functionalities such as automated driving, connectivity and cyber-security have gained increasing importance over the past few years. The importance of these functionalities will continue to grow as these cutting-edge technologies mature and market acceptance increases.

Hydraulics still in control of off-highway needs Engineers continue to master electronic controllers and software to help systems manage engine speeds and boost efficiency, to the ultimate benefit of both OEMs and end-users. Off-highway calibration challenges-big and complex As the final set of Tier 4 regulations kick in for engines greater than 750 hp (560 kW), calibration efforts must contend with complex engine and aftertreatment systems. Engine manufacturers and service providers deal with this complexity, but does it need to be so? DEF delivery modelling for SCR systems Researchers characterize a 0-D model of a urea delivery module, oriented to model-based control and to the simulation of the system response to fault injections finalized to diagnosis validation.

Getting a grip on AWD efficiency The safety and performance benefits of all-wheel drive are undeniable, but so are the penalties of added weight, friction losses, and complexity. Clever axle disconnects and E-axles are driving future AWD developments. E pluribus unum Inputs from many sensors are being combined to give safety systems a true vision of vehicle surroundings, with the resulting sensor fusion becoming a mainstay of autonomous vehicle electronics. Lightweighting poses repair challenges Mass-produced aluminum bodies and mixed-material structures present challenges for assembly and repair, as automakers increasingly pursue these lightweight strategies.

Cal State Fullerton combines art and engineering Team's submission on its Formula SAE car won first place in the second annual Generation Auto video contest organized in part by SAE International. Collaborative research project leads to potentially swarming VTOL UAVs The AVIGLE VTOL (vertical takeoff and landing) unmanned aerial vehicle was developed via collaboration by a variety of entities for a variety of applications.

How do you protect the computer systems that run automated cars from hacker attacks?

The group will classify attack methods, propose preventative strategies, define levels of security by criticality of system type, and identify architecture-level strategies for mitigating attacks.

Although in-vehicle vulnerabilities have been identified, others exist in cloud-based systems. Public facilities, from traffic-light-controlling central computers to non-automotive infrastructure, may have little or no protection, speakers asserted.

Upon their arrival, Unmanned Autonomous Systems (UAS) brought with them many benefits for those involved in a military campaign. They can use such systems to reconnoiter dangerous areas, provide 24-hr aerial security surveillance for force protection purposes or even attack enemy targets all the while avoiding friendly human losses in the process. Unfortunately, these platforms also carry the inherent risk of being built on innately vulnerable cybernetic systems. From software which can be tampered with to either steal data, damage or even outright steal the aircraft, to the data networks used for communications which can be jammed or even eavesdropped on to gain access to sensible information. All this has the potential to turn the benefits of UAS into liabilities and although the last decade has seen great advances in the development of protection and countermeasures against the described threats and beyond the risk still endures.

Finding ways to prevent cyber attacks on vehicles has the attention of the global automotive industry as well as a few high school and college students.

The federal government and industry have moved to concurrent acquisition and development processes using integrated process teams (IPTs). These processes are supported by timely, accurate, cross functional access to data within an integrated data environment (IDE) enabled by advances in information technology (IT). Since the advent of acquisition reform in 1994, Data Management (DM) practices have evolved from being directed by a prescriptive set of standards and procedures to use of the guidance in a principles-based standard -- ANSI/EIA 859.

GEIA Handbook 859 provides implementation guidance for ANSI/EIA 859, with discussions of applications of the standard's principles, tools, examples, and case studies. Handbook 859 is organized according to the lifecycle of data management and covers activities from the pre-RFP stage through records disposition.

Global Viewpoints The latest strategies are investigated for vehicle development by automakers and major suppliers. Sports cars embrace array of green technology IMSA Tudor United SportsCar Championship promotes a variety of green technologies to link racing to the road. More gears, more challenges Many strategies, as well as key software and hardware aspects related to controllers, networks, sensors, and actuators, must be considered to keep automatic transmissions shifting smoothly as more gears are added to improve fuel economy. Advancing structural composites Industry experts address the opportunities and challenges involved with moving toward composite-intensive vehicles, including Nissan's effort to produce a high-volume, fully recyclable composite liftgate with low metal content.

As vehicles become increasingly connected with the external world, they face a growing range of security vulnerabilities. Researchers, hobbyists, and hackers have compromised security keys used by vehicles' electronic control units (ECUs), modified ECU software, and hacked wireless transmissions from vehicle key fobs and tire monitoring sensors. Malware can infect vehicles through Internet connectivity, onboard diagnostic interfaces, devices tethered wirelessly or physically to the vehicle, malware-infected aftermarket devices or spare parts, and onboard Wi-Fi hotspot. Once vehicles are interconnected, compromised vehicles can also be used to attack the connected transportation system and other vehicles. Securing connected vehicles impose a range of unique new challenges. This paper describes some of these unique challenges and presents an end-to-end cloud-assisted connected vehicle security framework that can address these challenges.

This document provides background and detailed technical information on existing methods to secure loadable software parts.

Newer generations of aircraft in production and use today are equipped with security applications that rely on digital certificates. It is expected that future aircraft will use certificates for increasing numbers of applications. The purpose of this document is to provide guidance for key life-cycle management, which refers to the phases through which digital certificates and associated cryptographic keys progress, from creation through usage to retirement. The guidance is based on open international standards that are adapted to the aviation environment, recognizing that a typical commercial airplane has a long lifespan, its operational environment is highly complex and regulated, and multiple stakeholders operate ground-based systems that communicate with airplanes. Using a standardized and consistent key management approach, as proposed in this document, helps to reduce cost of design, implementation, and operation even across a heterogeneous fleet.
