Impact of Automated Lane Change Assist on Energy Consumption

Embry-Riddle Aeronautical University-Casey Troxler, Patrick Currier, Charles Reinholtz
  • Technical Paper
  • 2020-01-0082
To be published on 2020-04-14 by SAE International in United States
Automated lane change assist combined with adaptive cruise control has the potential to reduce energy consumption and improve safety. This paper models adaptive cruise control combined with automated lane change assist to investigate the energy consumption improvements that such a system may provide compared to conventional adaptive cruise control. Automatically executing a lane change may improve efficiency, for example, when following a vehicle that is slowing to make a turn. Changing lanes while maintaining speed should be more efficient than staying in the same lane as the turning vehicle and reducing speed. The differences in such scenarios are simulated in a virtual environment using a cuboid model with idealized sensors. The ego-vehicle will detect scenarios, evaluate if a lane change is feasible, and possibly perform a lane change to reduce or eliminate required speed changes. The results of the simulations compare the energy content of the resulting drive cycle as an idealized method to measure energy consumption for each cruise control strategy. The simulations consider traffic laws, such as turn signal requirements that may dictate…

Predicting Photometric Degradation of Exterior Aircraft Lights

A-20B Exterior Lighting Committee
  • Aerospace Standard
  • ARP6621
  • Current
Published 2019-12-09 by SAE International in United States
This Aerospace Recommended Practice provides guidance for designers and specifiers of aircraft exterior lighting. Typical causes of light degradation and methods of predicting performance degradation in the aircraft environment are given. Although the document considers only exterior lighting, many of the principles and methods discussed apply to interior or flight deck lighting as well.

Lighting Applications for Unmanned Aircraft Systems (UAS)

A-20B Exterior Lighting Committee
  • Aerospace Standard
  • ARP6336
  • Current
Published 2019-12-05 by SAE International in United States
This SAE Aerospace Recommended Practice (ARP) provides technical recommendations for the lighting applications for Unmanned Aircraft Systems (UAS). The technical content of this ARP discusses the unique trade-offs that are necessary to maintain commonality to the U.S. Federal Aviation Regulations (FARs)1 for aerospace lighting. The recommendations set forth in this document are to aid in the design of Unmanned Aircraft (UA) lighting for the size of aircraft and operation for which the aircraft is intended. In addition, certain concepts of operation for which UASs are suited will require unique lighting solutions.

Enhancing Flight Path Separation to Reduce Bird Strikes with Ultraviolet Radiation

SAE International Journal of Aerospace

Lite Enterprises, USA-Donald J. Ronning
  • Journal Article
  • 01-12-02-0005
Published 2019-10-29 by SAE International in United States
In the autumn of 2018, a pilot study using a prototype (PAR46 size) landing light that incorporated ultraviolet light emitting diodes (UVLEDs) was attached on a one-quarter scale remote controlled (RC) plane. The plane was flown in the direction of birds to measure their behavioral response to the approaching plane with landing lights either turned ON or OFF. Data were collected from multiple sources including cameras on the plane and the ground and a bird radar unit to measure the flight path separation between the plane and the birds. The purpose of this study was to determine the effectiveness of using UVLEDs integrated into a PAR46 landing light to trigger bird avoidance behavioral responses that would increase flight path separation to reduce the incidence of bird strikes. The findings showed the mean distance of the avoidance response was statistically significantly greater when the PAR46 landing light with UVLEDs was turned ON versus OFF. Field test data were used to create a three-variable model based upon recent neuroscience research corresponding to visual image capture, retinal neural…

Recommended Practice for Optimizing Automobile Damageability and Repairability

Motor Vehicle Council
  • Ground Vehicle Standard
  • J1555_201910
  • Current
Published 2019-10-24 by SAE International in United States
This SAE Recommended Practice applies to all portions of the vehicle, but design efforts should focus on components and systems with the highest contribution to the overall average repair cost (see 3.7). The costs to be minimized include not only insurance premiums, but also out-of-pocket costs incurred by the owner. Damageability, repairability, serviceability and diagnostics are inter-related. Some repairability, serviceability and diagnostics operations may be required for collision or comprehensive loss-related causes only. Some operations may be for non-collision-related causes only (warranty, scheduled maintenance, non-scheduled maintenance, etc.). Some may be required for both causes. The scope of this document deals with only those operations that involve collision and comprehensive insurance loss repairs.
