“We pay close attention to the SAE magazines because your guy in Europe writes interesting articles,” a BMW engineering executive told me one year at the Frankfurt Motor Show. He was referring to Stuart Birch, our veteran European Editor, who has recently decided - after nearly 37 years of outstanding reporting for SAE International - to hang up his keyboard and spend more time with his wife, Kim, their family and friends in the British countryside, and his classic Porsche 911. Our staff had been dreading the day that Stuart would announce his retirement, foremost because he's been a great friend as well as a colleague. And because journalists with his qualities - professionalism, perspective, a powerful work ethic and great wit - are increasingly rare in the mobility-technology space. As SAE's global audience knew, Stuart Birch delivered compelling technical and business information. He covered product, processes and people with equal poise. And he thrived on the R&D beat: Virtual

Engine-in-the-Loop Analysis of the Influence of Manual Gearshift Duration on Vehicle Consumption and Emissions15-16-01-000309/27/2022
Abstract The tightening of emission standards and homologation rules lead car manufacturers to rely on simulation testing in early development phases. Coupling an engine to a testbench controlled by a real-time simulation environment allows flexible, reliable, and reproducible testing for consumption and emission studies. However, interest in this method referred to as engine-in-the-loop (EiL) is relatively recent and few details can be found regarding the simulation environment. Following previous work, this study details a driver model based on the PI structure and augmented with preview and anti-windup. The focus is set on a conventional powertrain with a manual transmission for which the driver must also manage the clutch pedal during gearshift and take-off phases. Extended analysis of vehicle tests allows defining the driver’s behavior during these phases for different profiles. The driver model is then tested in the EiL environment and the impact of the gearshift profile on fuel

Mixed Reality Driving Simulator as a Training Tool for Autonomous Vehicles2022-01-097303/29/2022
While manufacturers have invested billions of dollars in the self-driving car technology, little has been done to prepare drivers to this paradigm shift in transportation. According to a recent survey published by PAVE (Partners for Automotive Vehicle Education, 2020) of 1,200 adult drivers, 48% of American drivers say they “would never get into a taxi or ride-share vehicle that was driven autonomously”. To overcome these issues and to address this problem, we developed a highly immersive driving simulator which provides a safe platform for drivers of all ages and abilities to get a first hand experience of a self-driving vehicle. The proposed system provides a highly innovative use of mixed reality and can be easily retrofitted to any vehicle to provide mechanical immersion. Visual immersion is obtained through a mixed reality experience delivered through a Head Mounted Display.

Impact of Automated Lane Change Assist on Energy Consumption2020-01-008204/14/2020
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 is hypothesized to 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 detects scenarios and performs 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 the distance

VR Helps Amputees ‘Feel’ Prosthetic LimbsTBMG-3563412/01/2019
Scientists have shown that amputees can actually be convinced that the prosthetic hand belongs to their own body. They do this by going beyond the “seeing is believing” idiom based on established research on how the brain identifies what belongs to its own body. Instead of using the sense of sight alone, they used an astute combination of two senses: sight and touch.
How Augmented Reality Can Modernize Aerospace And Defense ManufacturingTBMG-3568512/01/2019
You've probably heard about augmented reality (AR) in the context of consumer entertainment: video gaming, virtual tours, or interactive displays. But AR for enterprise business is here. It's no longer an emerging technology, or a novelty; businesses are using AR to overhaul processes, drive efficiencies, reduce manufacturing errors, and improve their bottom line.
Artificial Skin Provides Haptic FeedbackTBMG-3561612/01/2019
Technology capable of replicating the sense of touch — also known as haptic feedback — can greatly enhance human-computer and human-robot interfaces for applications such as medical rehabilitation and virtual reality. A soft artificial skin was developed that provides haptic feedback and, using a self-sensing mechanism, has the potential to instantaneously adapt to a wearer's movements.
Mathematical Technique Quickly Tunes Next-Generation LensesTBMG-3548011/01/2019
Most of us know optical lenses as curved, transparent pieces of plastic or glass, designed to focus light for microscopes, spectacles, cameras, and more. For the most part, a lens’ curved shape has not changed much since it was invented many centuries ago.
Artificial Skin Could Help Rehab, Enhance VRTBMG-3550811/01/2019
Researchers have developed a soft, flexible artificial skin made of silicone and electrodes. The skin’s system of soft sensors and actuators enable the artificial skin to conform to the exact shape of a wearer’s wrist, for example, and provide haptic feedback in the form of pressure and vibration. Strain sensors continuously measure the skin’s deformation so that the haptic feedback can be adjusted in real time to produce a sense of touch that’s as realistic as possible.
An IMPC Based Parking Assistance System2019-01-261410/22/2019
This paper summarizes progress and outcome from our research projects on IMPC-based parking management system, including parking motion planning and control strategy, as well as a searching strategy for parking spot. IMPC here refers to interactive model predictive control regime, which is characterized in that multiple agents implementing separate MPC strategy are incorporating information about their state, objective, and constraints. To predict future parking parameters, we proposed a practical framework which integrates anticipatory techniques with a model predictive approach that robustly models the stochastic parking environment. The framework is able to take into account the interactions between vehicle subsystems, and can optimize trajectory under complex traffic patterns in real-world scenarios. Adaptive model predictive control is utilized to optimally minimize a cost function regarding performance, energy efficiency and drivability with regard to surrounding vehicle states

Advanced Mathematical Modelling for Glass Surface Optimization with PSO2019-28-010410/11/2019
In automotive door engineering, fitting the side door glass surface from styling into the cylinder or torus is the basic requirement. Optimization is required to do this, which requires a solver which could be efficacious for best surface fitting. This paper propounds a methodology which could be used for fitting a side door glass surface from styling into the cylinder or torus. The method will significantly help in developing the required surface and can successfully eliminate the cumbersome manual calibrations. The mathematical model mentioned is a novel approach based on “Particle Swarm Optimization” (“PSO” will be used to represent in the paper) towards surface optimization technique. VB script is used to make it applicable in CATIA but could be easily applied in any other programming language like python, java etc. Usually the surface fitting problems deals with the initial guess of the required surface and then its further optimization. Herewith we have discussed some geometrical
