Bollinger Motors recently unveiled its second-generation Class-3 EV prototypes. The start-up, based in Ferndale, Michigan, revealed the latest beta of its B1 SUV and B2 truck prototypes, highlighting the amount of in-house engineering and design. As a Class 3 (GVWR 10,001 to 14,000 lb.) vehicle, the Bollinger Motors truck and SUV are in the same classification as a Ford F-350 or Ram/Chevy 3500 truck. “This is the only all-electric Class 3 truck with off-road capability,” founder and CEO Robert Bollinger said of the B2.

Vehicle Sound Package Materials Web Seminar RePlay

  • Webinar Recordings
  • PD331204ON
Published 2019-11-01
This four-session course provides a detailed understanding of the source – path-receiver relationship for developing appropriate sound package treatments in vehicles, including automobiles, commercial vehicles, and other transportation devices. The web seminar provides a detailed overview of absorption, attenuation (barrier), and damping materials and how to evaluate their performances on material, component, and vehicle level applications. A significant part of this course is the case studies that demonstrate how properly designed sound package materials successfully address vehicle noise issues.By participating in this course, you will be able to: Identify various descriptors that are used in acoustics while working with sound package materialsIdentify three fundamentally different sound package materials that are used in the industryExplain how these materials work and how to improve their performanceDescribe how various measurements are made and why they are necessary on a material level, component level, and vehicle levelPrescribe appropriate sound package materials for specific NVH issuesConstruct proper protocols for combining different sound package materials for different components so that the final vehicle meets the required acoustic target

After digesting some of the fascinating insights from surveys taken of automated-vehicle test riders - most of them first-timers - who participated in SAE International's Demo Days program (see pg. 31), you've got to conclude that the only thing predictable about the new-mobility landscape is its unpredictability.

The Road to Automobility

The era of electrified, self-driving vehicles is upon us. Engineers are key to the transformation - with much hard work still to be done.

In 1911, eight years after the Wright Brothers flew the first airplane, French general Ferdinand Foch dismissed the new technology. “Airplanes are interesting scientific toys,” he scoffed, “but they are of no military value.” World War I and the wave of aeronautical progress it triggered would prove Foch wrong. Today, automobility is the subject of a “hype or ripe” debate similar in spirit to what the airplane experienced in its nascent years.

A Montreal-based company leverages artificial intelligence to take on the task of developing high-definition maps of Canada.

Fully-automated vehicles will only be as smart as the datasets they use to determine their driving pathways. Jakarto Cartographie 3D, a young company based in Montreal, Canada, is working on artificial-intelligence (AI)-powered, high-definition (HD) maps that it claims offer 2-3 cm (.787- to 1.2-inch) absolute precision and relative precision measured in millimeters. In other words, better maps that will allow for better automated vehicles (AVs).

3D Sonar Sees Objects Overlooked by Costlier Sensors

A dream of robotic fish inspires inexpensive automated-driving sensing technology that works for the critical areas close to the vehicle.

Alexander Rudoy was spending almost every hour of his free time developing a robotic toy fish that could sense its underwater surroundings. At that time a decade ago, he was studying electromechanical engineering at the Munich University of Applied Sciences, where he earned a Masters degree in 2015. Rudoy never finished his robo-guppy, but even before graduating, he founded Toposens, a company that now utilizes the guppy's underlying close-distance ultrasound technology for a wide range of vital automated-vehicle operations.

STATE OF CHARGE

With just 16 hours to complete a three-state, 600-plus-mile roundtrip, we judge whether the nation's non-Tesla fast-charging network is a match for the new breed of long-range EVs like Jaguar's inspired 2019 I-Pace.

It's a trip we've done scores of times with barely a thought. From our home near SAE International headquarters in western Pennsylvania to the metro Detroit area is approximately 300 miles (483 km) of highway driving. We often do it in four-and-a-half hours without a stop of any kind, much less for fuel. Some diesels and hybrids, and even a few conventional gasoline vehicles, can knock off the entire roundtrip on a single tankful.

The TechCrunch Sessions at San Jose's Mobility 2019 conference advance the dialogue for real-world business cases for AVs.

An impressive lineup of the world's leading autonomous vehicle (AV) companies gathered in San Jose for the TechCrunch Sessions: Mobility 2019 conference. Technologists, executives and transportation experts took to the stage of the California Theater, a beautifully restored 1920s-era motion-picture house. The venue has a long legacy of presenting fantastical movies, operas, and vaudeville shows. However, the day-long, back-to-back 20-minute conversations on stage struck a note of hyper-realism.

Led by GKN, the ACeDrive consortium is developing lighter and more-efficient EV propulsion, targeting volume production in 2023.

It's called ACeDrive, which may sound innocuous for an auto-industry project. But the consortium that formed it has announced that it seeks to develop the world's lightest and most efficient volume electric vehicle (EV) powertrain. Involving two major suppliers, a research university and the UK government-backed Advanced Propulsion Centre (APC), the aggressive targets for the ACeDrive (Advanced Cooling and Control of high speed e-Drive) include a 25% reduction in cost, a 25% reduction in packaging size and a 20% reduction in weight combined to deliver a 10% increase in efficiency.

“Today a bunch of idiot lights appeared in the minivan during my drive to work,” reported my spouse, Suzie, after she arrived home one evening last month. Sure enough, the cluster on our 2011 Honda Odyssey lit up like a Christmas tree when I turned on the ignition to investigate. The Check Engine light and two others were illuminated.
