Exterior Lighting Recommendations for Urban Air Mobility and Electric Vertical Takeoff and Landing Aircraft

2022-10-12
WIP
ARP7216
This document covers external lighting for Electric Vertical Takeoff and Landing (E-VTOL) and Urban Air Mobility (UAM) vehicles. It discusses lights that may be installed both to meet regulatory requirements as well as for customer comfort and aircraft recognition. It also discusses the differences between UAM vehicles and other aircraft and how those differences impact the lighting.

A Rule-based Collision Avoidance System – Scene Interpretation, Strategy Selection, Path Planning and System Intervention

2009-04-20
2009-01-0156
To reduce accidents and fatalities on the roads, active safety systems which can avoid accidents or mitigate their effects are increasingly required. Contrary to already available driver assistance systems a future system can be a Collision Avoidance System which will be able to solve many critical traffic situations by warning, braking or steering. This paper will present a system consisting of environment sensing and situation analysis blocks as well as intervening strategy blocks. The main focus will be put on the scene interpretation of a situation and its optimization. Therefore a rule-based Fuzzy System will be described. Furthermore the Strategy Selection and the Path Planning in case of system intervention will be shown by simulation. The system has been developed during the work at the Adam Opel GmbH.

Information Report on HPSE Trusted Applications Threat Analysis

2022-10-13
WIP
J3101-2
In this report we aim to complete HPSE trusted applications threat analysis to determine the effectiveness of isolation security models and suggest HPSE isolation building blocks. The report will enumerate the threats applicable to HPSE trusted applications based on their deployed use case and suggested security models for manufacturers based on their risk profile.

An Information Report on Side Channel Attacks

2022-10-13
WIP
J3101-4
In this report, we aim to create a survey of side channel and fault injection attacks that have an impact on automotive embedded systems. The report will provide a taxonomy of attack types and suggested countermeasures that can be considered by manufacturers based on the their risk tolerance to such attacks. Additionally, the report will provide a common language to facilitate the communication of side channel and fault injection mitigation requirements among the various stakeholders.

Explicit Equations to Estimate the Flammability of Blends of Diesel Fuel, Gasoline and Ethanol

2020-09-15
2020-01-2129
Blends of gasoline, diesel fuel and ethanol (“dieseline”) have shown promise in engine studies examining low temperature combustion using compression ignition. They offer the possibility of high efficiency combined with low emissions of oxides of nitrogen and soot. However, unlike gasoline or diesel fuel alone, such mixtures can be flammable in the headspace above the liquid in a vehicle fuel tank at common ambient temperatures. Quantifying their flammability characteristics is important if these fuels are to see commercial service. The parameter of most interest is the Upper Flammable Limit (UFL) temperature, below which the headspace vapour is flammable. In earlier work a mathematical model to predict the flammability of dieseline blends, including those containing ethanol, was developed and validated experimentally. It was then used to study the flammability of a wide variety of dieseline blends parametrically.
