Design teams are targeting focused markets for their commercial electric-vehicle programs to combat challenges like range and infrastructure.

Government regulations are prompting a changeover to electric powertrains, with early growth coming in commercial vehicle applications where range and recharging are more easily managed. Greater expansion will require revisions in maintenance and broader availability of charging stations as well as improved driving ranges.

The 49th annual SPE Automotive Awards highlight the ongoing benefits of lightweight polymers and composites.

The Society of Plastics Engineers (SPE) annual Automotive Innovation Awards Competition, now in its 49th year, is considered the “Oscars” for those developing polymer and composites-intensive components, systems and vehicles. Winners of the 2019 competition topped an incredible field of entries that continue to show the benefits of lightweight, durable plastics across the spectrum of vehicle applications.

Fuel-cell technology is a big subject with some very small but vital aspects, one of which is the size of platinum atoms. Reduce these and the cost of platinum-one of the major drawbacks of current fuel-cell systems-would also fall. So, establishing and creating the optimum size for platinum fuel-cell catalysis for cars and heavy-duty trucks is one of the ongoing research areas for future alternative energy solutions.

Together with its many partners, ZF supplies camera and radar technology and advanced components for both the passenger car and commercial truck markets, the latter being especially suited for the move to more complex driver-assistance systems, according to Dan Williams, director of ADAS & Autonomy at ZF. “The business case in commercial vehicle for reduction in driver hours of service, fuel cost reduction and safety have strong economic incentives to adopt ADAS/automated driving technology. Additionally, the regulations placed on the industry will require our customers to utilize certain solutions,” he said.

Researchers at the Austrian Institute of Technology have developed an air exchange system that's capable of reducing heat load by 37% in real-world tests.

Battery-electric vehicle (BEV) range loss from winter use of PTC (positive temperature coefficient) heating has become a source of major concern as the industry works to make EVs a mainstream choice. Addressing this particular problem area with an economically viable solution was deemed a worthwhile effort by the Austrian Institute of Technology (AIT), which is jointly owned by the Austrian government and the Federation of Austrian Industries. A fleet test of electric delivery trucks is underway on European roads.

Removing complexity for AUTONOMOUS TRUCKS

Narrowing the operating domains for driverless commercial vehicles reduces the requirements of autonomous technology and speeds time to market.

Developers of driverless trucks are eliminating some of the complexity of automated driving in hope of hastening time to market. They are limiting the nearly immeasurable scope of circumstances - the operating design domain (ODD) - that face driverless vehicles by deploying a variant of platooning, or narrowing the operational parameters for transporting goods. Driver shortages, growth in shipments of online purchases and the never-ending push to trim costs are among the factors that have led many to predict that commercial trucking will be an early adopter of autonomy.

Two years ago at the inaugural North American Commercial Vehicle (NACV) Show in Atlanta, a recurring theme from nearly every truck manufacturer and supplier press conference was vehicle uptime, along with the various telematics and connectivity solutions that enable fleet managers to keep their trucks on the road. While these certainly were important topics at this year's NACV Show, the dominant takeaway from the Georgia World Congress Center was that alternative propulsion is top of mind for many industry players.

Covering about 2.5 million ft2 and including roughly 2,800 exhibitors, the triennial ConExpo-Con/Agg event boasts an evenlarger footprint for 2020 with the addition of the Festival Grounds. As one of the major exhibitors at North America's largest construction tradeshow, taking place March 10-14 in Las Vegas, Caterpillar will have a fairly significant footprint of its own, filled with new equipment featuring the company's latest technology developments. A few of the machines likely to be on display were revealed at an October 2019 press event in Clayton, NC.

The past three years have seen a major shift in the perception around electrified commercial vehicles, including trucks, driven by a variety of factors that have come together at this particular time. These factors include a growing awareness and acceptance of the impact of CO2 emissions on climate change and the dangers of diesel emissions-most notably highlighted by the Volkswagen emissions scandal-alongside a growing maturity and improved cost profile on electric vehicle (EV) technology. As a result, fleet owners and OEMs now consider e-trucks much more seriously.
