Autonomous Vehicle Engineering: March 2018

2018-03-08
Editorial Autonomy's data binge is more like a 5-course meal. Big Data, Big Challenges Cloud services and multiple partnerships are issues the mobility industry grapples with as data implications expand outside the vehicle. Reinventing the Automobile's Design The convergence of electric propulsion, Level 5 autonomy, and the advent of car-free urban zones, is driving new approaches to vehicle design and engineering. When Steering Isn't Steering Anymore High-level autonomy requires new thinking for even basic vehicle controls. Steer-by-wire technology eases some of the complexities automated driving presents-and offers desirable new possibilities. Autonomy and Electrification: A Perfect Match? Combining SAE Level 4/5 functionality and EV platforms brings chal-lenges-and opportunities for cost reduction and systems optimization. Who's Ahead in the Automated-Driving Race? The 2018 Navigant Research Leaderboard study brings interesting insights on the industry's progress.

Death Rays, Jet Packs, Stunts and Supercars: The Fantastic Physics of Film's Most Celebrated Secret Agent

2005-01-01
James Bond would have died a thousand deaths if not for Q, the genius behind the pen grenades and weaponized sports cars that have helped Britain's most famous secret agent cheat death in twenty films. Here Barry Parker demonstrates how science and technology have been as important to 007 as good looks, shaken martinis, and beautiful women. Using entertaining sketches and nontechnical language, Parker explains the basic physics behind the gadgets, cars, and stunts in a number of Bond films, from the jet packs in Thunderball to the dynamics of daredevil bungee jumping in GoldenEye. If you've ever wondered whether the laser could have actually cut Bond in half (Goldfinger), if a wristwatch could really unzip a woman's dress (Live and Let Die), or whether your car could do the 360-degree barrel roll from The Man with the Golden Gun, this book is for you.

Autonomous Vehicle Engineering: May 2018

2018-05-03
Editorial Tragedy to Transform AV Testing? Detecting Pedestrians Safety of vulnerable road users is driving new technologies as pedestrian deaths rise worldwide. When Autonomy Underperforms: the Evolving Liability Model As autonomy-related accidents expand, expect legal liability to shift to products rather than people. Seeing Through Fog Fog, rain and snow are big challenges for optical sensors, particularly active systems. Engineers need to understand the impact of fog conditions on cameras and thermal sensors used in AVs. Rethinking Architectures: From Chips to the Cloud New concepts and strategies for controls architectures are emerging as AV boundaries expand and options skyrocket. Cabin Fever As humans do less actual driving, autonomous vehicle interiors will transform radically to provide more creature comforts. Threat Vector: Car Washes! For vehicles with automated-driving sensors, the “cleansing” experience can go too far.

Multifunctional Glasses for Automotive

1996-04-01
91A109
The windows of a vehicle have to satisfy the following driver and passenger needs concerning visibility and climate perception both related to active safety: transparency, reluctance, dazzling, glare and diffused light (scattering). All functions are related to visibility and so to the optics of glazing, solar control, deicing, defogging, demisting. The task of material science is to find the multifunctional glasses solving simultaneously problems of visibility, safety and comfort. Particular kind of glasses, colored, wired, coated, electrochromic, liquid crystal, photochromic can be already considered solutions which can operate passively or actively. The example of passive solar control and active heatable coated glasses is shown as a possible practical multifunctional glass very soon.

Predictable and unpredictable forces will change the direction of the charge-air systems industry. The driver of diesel engine development will be the stringent emissions regulations of the 1990s. The drivers in the gasoline engine market will be improved fuel economy, performance, durability and emissions. Forces will also influence the charge-air marketplace, including changes in emission standards, national fiscal policies, political issues, fuel prices, alternate fuels and consumer tastes. The world community mandate for engines that are clean, quiet, durable and fuel efficient will be satisfied, increasingly, by first-tier component suppliers developing integrated systems solutions.

“Passenger Vehicle Petrol Consumption - Measurement in the Real World”

1988-03-01
871159
A survey of the in-service fuel consumption of passenger vehicles and derivatives in the Australian fleet was carried out in 1984-85. Seven hundred and four owners across Australia took part in the survey. Vehicle owners reported by questionnaire the amount of fuel used during four tank fills of normal operation, the distance travelled, and other details of the operating circumstances. The survey shows a clear downward trend in the fuel consumption of the Australian passenger fleet. The data also provides comparisons of actual fuel consumption obtained on the road, with laboratory derived values for fuel consumption. Vehicles in a sub-set of 40 were fitted with fuel flow meters during the survey and tested to Australian Standard 2077 for fuel consumption. The questionnaire method is shown to be a valid and accurate technique for determining in-service fuel consumption.

A Study on the Performance of Guideway Bus Steering Control System

1988-03-01
871231
In this paper a computer simulation study on the effects of steering parameters on lateral dynamics of the guideway bus to contribute to a development practice of designing optimum steering control system are dealt with. A stability limit of vehicle lateral motion is analyzed and an emphasis is laid on the effects of moment of inertia of a conventional steering wheel and lateral elasticity of the guide rail which have proven to reduce the critical vehicle speed. It is pointed out conclusively that a normal bus equipped with additional simple guidance equipments can be guided smoothly on a simple guideway at adequately high vehicle speed.

Electric Vehicle Sound Quality

1999-05-17
1999-01-1694
Environmental concerns as well as regulatory requirements are driving the development of alternative vehicle propulsion systems. Electric vehicles (EV's) are attractive because they emit no pollutants. In this paper, we examine the sound quality characteristics of wind and powertrain noise in electric vehicles. Sound quality is an important attribute of EV's, because the expectation is that they will be very quiet due to the absence of an internal combustion engine. As we show in this paper, the absence of engine noise is both a blessing and a curse for sound quality. For wind noise, the results show that electric and gasoline vehicles have equivalent wind noise loudness levels at all speeds. However, at lower speeds (50-60 mph), the EV is judged to have more wind noise even though the level was the same as the gasoline vehicle! The difference is that, in the EV, there is no engine noise to mask the wind noise.
