Abstract The automotive industry continues to develop new powertrain and vehicle technologies aimed at reducing overall vehicle-level fuel consumption. Specifically, the use of electrified propulsion systems is expected to play an increasingly important role in helping OEM’s meet fleet CO2 reduction targets for 2025 and beyond. Electric and hybrid electric vehicles do not typically utilize IC engines for low-speed operation. Under these low-speed operating conditions, the vehicles are much quieter than conventional IC engine-powered vehicles, making their approach difficult to detect by pedestrians. To mitigate this safety concern, many manufacturers have synthesized noise (using exterior speakers) to increase detection distance. Further, the US National Highway Traffic Safety Administration (NHTSA) has provided recommendations pursuant to the Pedestrian Safety Enhancement Act (PSEA) of 2010 for such exterior noise signatures to ensure detectability.

This report lists documents that aid and govern the design, development, and utilization of aerospace electronic engine control systems. The report lists the military and industry specifications and standards that are commonly used in electronic engine control system design. However, this list is not necessarily complete. The specifications and standards section has been divided into two parts; a master list arranged numerically and a categorized list that provides a functional breakdown and cross reference of these documents. For specifications and standards, the issue available during the latest revision to this document is listed. Details of current revisions for many documents are available in the Department of Defense Index of Specifications and Standards (DODISS).

The goal of the Pedestrian Test Mannequin Task Force is to develop standard specifications/requirements for pedestrian test mannequins (1 adult and 1 child) that are representative of real pedestrians to the sensors used in Pedestrian Detection systems and can be used for performance assessment of such in-vehicle systems (including warning and/or braking) in real world test scenarios/conditions. This version of the document only includes the pedestrian mannequin for vision, Lidar, and/or 76 to 78 GHz radar based Pedestrian Pre-collision systems.

Abstract Antilock braking systems (ABS) are inherently limited by the static coefficient of friction (µ) between a vehicle’s tires and the road surface. This paper explores a unique active safety concept, Integrated Coefficient Enhancement (ICE), which works to improve ABS well beyond their present limits. The ICE concept was developed using a basic physics principle: to change µ between two surfaces, at least one of the surfaces must be altered in some way. By quickly deploying a specially designed tractive medium (TM) to aid in directional stability and braking, hazardous situations can be greatly mitigated. This paper describes the features and testing results of this TM and its aerodynamic-mechanical-electronic deployment apparatus. Under all slippery road conditions tested, the developed TM mitigated skidding, with improvements that ranged from 20% to several hundred percent, depending on conditions and deployment rates.

The purpose of this information report is to present the factors that affect the design and development of aircraft jet blast windshield rain removal systems. Rain removal system design will generally be unique to specific aircraft. Design of these systems typically requires a preliminary design for the system based on available empirical data to be followed with a laboratory development program and a flight test validation program. Published windshield rain removal performance test data is available only for limited windshield configurations.

Many autonomous driving plans call for deploying a handful of solid state Lidar sensors on each vehicle, but the Lidar modules used on today’s prototype vehicles are all mechanical systems with moving parts. That’s prompted huge interest in solid-state Lidar, with OEMs and suppliers racing to invest in non-mechanical technologies.
