To be published on 2020-04-14 by SAE International in United States
The traffic volume of commercial vehicles is large in Chinese mountainous area. The heavy, frequent workload and the unreasonable driver’s habits of those commercial vehicles on mountainous roads will increase the fuel consumption. In order to improve the vehicle fuel economy, this paper design and study an intelligent speed planning system based on the driver’s behavior, which aims to planned the economy speed during the commercial vehicle runs on the mountain road. By combining the vehicle characteristic parameters with the feature of the mountain road for reminding the driver of the current vehicle speed in the form of human-computer interaction, the system could guide the driver to drive the commercial vehicle at a safe and economical speed, and thus improving fuel economy. An automotive parameter estimation model, a road feature parameter calculation model and an economic speed planning for the top place of a ramp were obtained based on the automotive dynamics. And a driver feedback model, a human-computer interaction guidance model were also built in this paper. The installation position of the human-computer interaction…

Research on Correction Algorithm of Head-up Display System in Vehicle Vibration

Wuhan Univ. of Technology-Jianjie Kuang
  • Technical Paper
  • 2020-01-1368
To be published on 2020-04-14 by SAE International in United States
The HUD(Head Up Display) system can superimpose the driving assistance information on the reality to assist the driver in driving. However, when the road conditions are quite bad, the driving assistance information could not coincide well with the reality. This paper presents a correction algorithm for a heads up display system. The algorithm calculates the offset between the driving assistance information and the reality according to the unevenness of the road and the inclination of the vehicle, and then adjusts the position of the driving assistance information. In this paper, according to the unevenness of the road, the algorithm could confirm the tilt state of the vehicle and calculate the tilt angle of the vehicle. The offset of the driving assistance information is calculated according to the inclination angle of the vehicle, and then the position of the driving assistance information is adjusted to coincide with the reality. Finally, a mathematical simulation model is established to verify the reliability of the correction algorithm by inputting the unevenness of the road and the position of the…

Photometric and Colorimetric Measurement Procedures for Airborne Electronic Flat Panel Displays

A-20A Crew Station Lighting
  • Aerospace Standard
  • ARP4260B
  • Current
Published 2019-09-17 by SAE International in United States
This SAE Aerospace Recommended Practice (ARP) contains methods used to measure the optical performance of airborne electronic flat panel display (FPD) systems. The methods described are specific to the direct view, liquid crystal matrix (x-y addressable) display technology used on aircraft flight decks. The focus of this document is on active matrix, liquid crystal displays (LCD). The majority of the procedures can be applied to other display technologies, however, it is cautioned that some techniques need to be tailored to different display technologies. The document covers monochrome and color LCD operation in the transmissive mode within the visual spectrum (the wavelength range of 380 to 780 nm). These procedures are adaptable to reflective and transflective displays paying special attention to the source illumination geometry. Photometric and colorimetric measurement procedures for airborne direct view CRT (cathode ray tube) displays are found in ARP1782. Optical measurement procedures for airborne head up displays (HUDs) can be found in ARP5287. Generally, the procedures describe manual single point measurements. The individual procedures may be readily incorporated into automated testing equipment…

Evaluation of Different ADAS Features in Vehicle Displays

University of Michigan-Abhishek Mosalikanti, Pranove Bandi, Sang-Hwan Kim
Published 2019-04-02 by SAE International in United States
The current study presents the results of an experiment on driver performance including reaction time, eye-attention movement, mental workload, and subjective preference when different features of Advanced Driver Assistance Systems (ADAS) warnings (Forward Collision Warning) are displayed, including different locations (HDD (Head-Down Display) vs HUD (Head-Up Display)), modality of warning (text vs. pictographic), and a new concept that provides a dynamic bird’s eye view for warnings.Sixteen drivers drove a high-fidelity driving simulator integrated with display prototypes of the features. Independent variables were displayed as modality, location, and dynamics of the warnings with driver performance as the dependent variable including driver reaction time to the warning, EORT (Eyes-Off-Road-Time) during braking after receiving the warning, workload and subject preference. The primary results were in line with previous research, validating previous claims of the superiority of HUD over HDD in warning delivery. It was also found that the text format of the warning yielded higher response rates along with lower workload, while most participants preferred the dynamic bird’s eye view layout.

Efficient Method for Head-Up Display Image Compensation by Using Pre-Warping

Hyundai Mobis-Mijin Jeon, Youna Lee
Hyundai Motor Group-Iksoon Lim
Published 2019-04-02 by SAE International in United States
A Head-Up Display (HUD) is electrical device that provides virtual images in front of driver. Virtual images are consists of various driving information. Because HUD uses optical system there exist image distortions with respect to image height and driver’s eye position. Image warping is image correction method that makes a geometrical change on image to minimize image distortions. In this paper to minimize image distortions, we use optical data driven warping matrix for each image height. But even though we applied data driven warping matrix, image distortions occur due to assemble and manufacturing tolerances when HUD is built. In this paper, we also suggest pre-warping method to minimize image distortions considering tolerances. We simulated 3 compensation functions to get rid of image distortions from the tolerances. By using proposed pre-warping method we could reduce maximum x, y distance by 31.5%, 39% and average distance by 32.2%, 27.9% of distortions.

Hazard Cuing Systems for Teen Drivers: A Test-Track Evaluation on Mcity

DENSO International America Inc.-Yu Zhang, Te-Ping Kang
University of Michigan-Michael Flannagan, Shan Bao, Anuj Pradhan, John Sullivan
Published 2019-04-02 by SAE International in United States
There is a strong evidence that the overrepresentation of teen drivers in motor vehicle crashes is mainly due to their poor hazard perception skills, i.e., they are unskilled at appropriately detecting and responding to roadway hazards. This study evaluates two cuing systems designed to help teens better understand their driving environment. Both systems use directional color-coding to represent different levels of proximity between one’s vehicle and outside agents. The first system provides an overview of the location of adjacent objects in a head-up display in front of the driver and relies on drivers’ focal vision (focal cuing system). The second system presents similar information, but in the drivers’ peripheral vision, by using ambient lights (peripheral cuing system). Both systems were retrofitted into a test vehicle (2014 Toyota Camry). A within-subject experiment was conducted at the University of Michigan Mcity test-track facility. The study collected data from seventeen teen participants. Each participant experienced three cuing conditions (focal cuing, peripheral cuing and dual system cuing conditions) as well as three no cuing system conditions (two practice, a…

Reviewing the latest tech applications in the automotive space and the trends they're serving.

With massive shifts looming in the automotive engineering space - the titanic trio of Autonomy, Mobility and Electrification (AME) - it's easy to forget that the pace of innovation continues unaltered in the here and now. We've reviewed the latest technologies on the newest OEM models and how they point to current trends in the automotive landscape. Though the AME macro trends represent the majority investment in the automotive space, and work on traditional engineering projects including new powertrains continues, small features that resonate often serve as a guideposts to what's next.
