Two decades ago, the Federal Communications Commission decided to allocate a portion of the radio frequency spectrum for Dedicated Short Range Communications (DSRC). The plan was to utilize that slice of the airwaves for ultra-modern automotive technologies relating to vehicle-to-vehicle and/or vehicle-to-infrastructure communications. Unfortunately, there hasn’t been a whole lot of activity on those channels.

The automotive industry was concerned it might need dedicated frequencies for use in autonomous-vehicle applications or some, yet unknown, technological advancement. But cable companies are annoyed that it’s being “wasted” and have started to antsy. They’ve asked the FCC to revoke carmakers’ exclusive rights to the frequencies and reallocate the majority of the 5.9-GHz band to the Wi-Fi systems that currently carry internet traffic for cable customers.

Hoping to encourage the commission to see things its way, Ford took FCC Chairman Ajit Pai out for a ride in an extra-special F-150 to plead its case. However, I feel like I can already predict whose side he’s going to take on this issue… and it isn’t going to be the automakers’.  (Read More…)

The Federal Communications Commission has decided to review how the radio spectrum intended for wireless communications should be divided. While a seemingly normal part of its duties, the reassessment could open up a part of the spectrum that was previously reserved for automotive applications. The super-high 5.9 GHz frequency reserved for cars was deemed important because it would help enable low-power connectivity in remote and high-density areas, allowing for vehicles to more reliably transmit information between each other and the infrastructure. This was framed by the interested parties as essential for helping to develop safe, autonomous driving systems but it could likely also work to aid any data-based services they offer in the future.

Meanwhile, cable companies, the telecom industry, and internet service providers (ISPs) don’t think it’s fair that automakers are getting their own slice of bandwidth when they’re not even using it yet. Carmakers have been working on vehicle-to-vehicle (V2V), vehicle-to-infrastructure, and dedicated short-range communication (DSRC) for years without much in the way of consumer applications.  (Read More…)

With Honda and General Motors teaming up on a self-driving car and GM’s Super Cruise getting the green light from Consumer Reportsit’s already been a busy week for automotive autonomy — and it’s only getting busier.

The U.S. Transportation Department plans to repudiate 10 locations previously outlined by the previous administration to serve as federally recognized proving grounds for self-driving vehicle tech. But don’t think for a second that this means the noose is tightening around the neck of autonomous testing. The Trump administration is preparing a new initiative that will lead to nationwide testing from just about anyone who can cobble together a vehicle with advanced driving aids.  (Read More…)

Car noise hearing

One of the benefits touted by early electric car advocates was a reduction in noise pollution stemming from automobiles. Electric motors have the potential to run far quieter than their internal combustion rivals, which could result in softer-sounding roadways.

The U.S. Department of Transportation started seriously worrying about the safety implications of silent-running vehicles back in 2010. Still, it wasn’t until this year that it legally imposed artificial noises on EVs as a way to warn inattentive or impaired pedestrians. Starting in 2020, vehicles with a GVWR of less than 10,000 pounds must emit a pedestrian-warning noise at speeds below 18.6 miles per hour.

However, despite a lengthy dialogue between government and industry, Ford was apparently seeking an exception for the federally mandated noise maker(Read More…)

First ordered by Congress in 2010 and delayed endlessly ever since, the U.S. Department of Transportation has finalized a date for the end of “noiseless” electric vehicles and hybrids: September 2020.

That’s a year after the previous deadline, announced in the final days of the Obama administration in November 2016. The National Highway Traffic Safety Administration subsequently froze the date in order to hear arguments from automakers. With that process now wrapped up, the new (and unchanged) rules mean any four-wheeled vehicle with a GVWR of less than 10,000 pounds must emit a pedestrian-warning noise at speeds below 18.6 miles per hour.

Enjoy the “silence” while you can. (Read More…)

tired driver woman yawning

Back in 2014, an American Automobile Association study estimated that tired motorists were responsible for around 328,000 accidents annually — 6,400 of which were fatal. However, unlike drunk driving, there’s no sound metric for assessing the true scope of the problem. Getting tired is something that just sort of happens. People don’t stay out all night not sleeping because it’s fun, the police can’t test for it, and almost nobody is going to say they were dozing off behind the wheel in an accident report — either because they are too embarrassed or stopped feeling tired at the moment of their brush with death.

That makes the issue a bit of a phantom menace. We all know it’s a problem, but the frequency remains debatable. Fortunately, a new study released by AAA this week helps clear things up. Researchers affixed dashboard cameras to 3,593 vehicles in order to monitor the drivers’ faces, then used a PERCLOS-based fatigue monitoring strategy to come to the conclusion that drowsiness is a contributing factor in 10.6 to 10.8 percent of all accidents resulting in significant property damage, airbag deployment, or injury.

fuel gauge

A bipartisan pair of congressional representatives from Michigan are proposing a new bill, the Fuel Economy Harmonization Act, that would aid automakers in complying with federal fuel efficiency requirements. Introduced on Wednesday, the bill would extend the life of fuel economy credits that are set to expire in five years and raise the ceiling on transferrable credits between car and truck fleets. Under the proposal, manufacturers could also be given additional credits for lowering fleet-wide emissions under new metrics.

Penning the bill, congresspersons Fred Upton (Republican) and Debbie Dingell (Democrat) said they believed the automotive industry would benefit from having a single set of fuel rules. The bill suggests rolling the NHTSA’s Corporate Average Fuel Economy (CAFE) and the EPA’s light-duty vehicle Greenhouse Gas Emissions mandates into one cohesive program.

While economy mandates have been growing, nationwide fuel consumption has still gone up. Likewise, the average mpg of cars sold in the United States hasn’t changed much over the last three years. With pump prices remaining low, consumers have flocked to less-efficient models like crossovers and SUVs.  (Read More…)

dot headquarters

Last week, we discussed how the National Highway Traffic Safety Administration had some staffing gaps that needed shoring up. While it remains shy one administrative head, the White House saw fit to officially appoint a new deputy administrator — effectively replacing acting deputy administrator Jack Danielson’s interim leadership.

Danielson has served as the NHTSA’s executive director since 2015, but spent the last eight months filling in for an absent department figurehead. He’s being relieved by Heidi King, an economist with the federal government and experience in the private-sector. (Read More…)

Trump

Supposedly, everyone eagerly anticipates the day they can own a shiny-new self-driving car, but automakers, regulatory agencies, consumer advocates, Silicon Valley, and the White House are debating how exactly that’s supposed to happen. They haven’t reached a consensus yet — and that’s probably not likely to change anytime soon.

Most autonomous cars rely on array of cameras, LIDAR, GPS, inertial measurement devices, and complex control systems used to interpret sensory information before reacting accordingly. Vehicle-to-vehicle communication systems (V2V) are regarded by many as essential components to establishing fully automated travel. The theory is that, by allowing cars to communicate directly on a broadband frequency, they can better predict each other’s movements.

However, a recent Bloomberg article accuses the technology of “going nowhere fast,” citing the Trump administration as the chief culprit, and alluding to the direct stifling of technology that would give cars “superpowers” in the next few years.

I probably won’t have the opportunity to say this often — and it feels kind of strange to say it now — but these accusations aren’t entirely fair to the president or his administration.  (Read More…)

vision 2.0 NHTSA Autonomous vehicles

On Tuesday, Transportation Secretary Elaine Chao outlined the Trump administration’s “Vision for Safety 2.0” at the University of Michigan’s Transportation Research Institute in Ann Arbor. The document is a collection of non-binding requests to manufacturers and a promise that they can go hog-wild with their autonomous vehicle testing, at least as far as the feds are concerned.

In a deluge of policy updates, the National Highway Traffic Safety Administration tweaked its vision for safety, claiming it was responding to the recent increase in the number of road accidents.

While Obama-era guidelines weren’t particularly robust, the Trump administration has essentially built a technical-sounding framework aimed at destroying regulatory red tape. Ironically, the government seems to have gone out of its way to ensure it stays out of the way. In some respects, it has to. The speed of development is beginning to happen at a rate where any outside bureaucracy would have difficulty keeping pace. Chao said the guidance would remain flexible, ready to adapt to the changes as they come. But it is also without teeth, promoting development and the future promise for safety at the expense of any meaningful oversight.

Did the Department of Transportation and NHTSA sell themselves out to industry or do they actually think giving automakers carte blanche on autonomous testing was the best thing for public safety? (Read More…)

pumping fuel

While the Trump administration continues gearing itself up to loosen fuel standards for automakers, much to the chagrin of environmentalists and other countries, the agencies that set those benchmarks want to pick your brain a little before making a final decision. You’ve got an opportunity to be part of the process — the painfully boring, yet incredibly important, process.

On Thursday, the U.S. Environmental Protection Agency and the Department of Transportation opened a public comment period on the reconsideration of the standards for greenhouse gas emissions for light vehicles built for the 2022-2025 model years. Additionally, the EPA wants comments on the appropriateness of the existing 2021 standards. The agencies are inviting the public to submit any relevant (i.e. factual) data and information that can inform a final decision of the standards.  (Read More…)

I have a 2000 Dodge Durango (wrote about the brakes on it before, all is good with them) and the lights are not the greatest. After replacing the passenger side due to a deer ramming its butt into it, its headlights no longer match. I’ve looked on several Mopar forums and there doesn’t seem to be any consensus on which lights are good — but they can all agree on what is crap.

So, I am willing to spend $300 on a proper headlight upgrade if that’s what it takes. I see a few conversions where you bake the headlights at low temp to release the glue and then put bi-xenon with the flappy shield in with the ballasts and wiring kit. They sound reasonable but there are some other projector-style lights out there that would be less work if they are focused and aligned properly. I’m mechanically inclined but with family and other projects I would rather spend less time on these and more time on replacing stuff like the worn grommets on the electric seat adjustment screws and such. (At 190,000 miles, it needs front suspension bushings, too.)

The U.S. Department of Transportation wants to mandate speed-limiting devices on all tractor-trailers and buses in the country in a bid to save lives and fuel.

Announced yesterday by the National Highway Traffic Safety Administration, the proposal would limit vehicles with a gross vehicle weight rating of 26,000 pounds or more to 60, 65, or 68 miles per hour. Other speed limits could be considered, but that’s up to the public to debate. (Read More…)

V2V Intersection

The Alliance of Automobile Manufacturers on Thursday sent a letter to the heads of the Federal Communications Commission, U.S. Department of Transportation and U.S. Department of Commerce, urging the groups to keep dedicated a frequency spectrum for future car communication systems.

The spectrum, which is between 5.850 GHz and 5.925 GHz, was allotted to automakers for car-to-car communication and road-to-car communication. Telecommunications and Wi-Fi industry officials have asked to share the spectrum.

“Um, no,” in the nicest possible way, from the Alliance:

We are committed to finding the best path forward to protect the development and deployment of advanced automotive safety systems while also considering the need for additional unlicensed spectrum to meet the increasing demand for wireless broadband Internet services.
