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…)

cadillac super cruise

General Motors intends to start offering its hands-free driving system, Super Cruise, across the entire Cadillac lineup by 2020. The technology, already available on the CT6, allows motorists to take a semi-passive role on the highway. Once GM’s luxury brand is sorted, the system will become available on other makes.

If you like the idea of a car that can take you out of the commute a bit and don’t mind the idea of a small camera permanently pointed directly at your face, then this is probably very exciting news.

While Super Cruise is frequently compared to Tesla’s Autopilot, the two operate differently. General Motors’ system does indeed allow for a similar hands-free experience, but the onboard camera tracks the driver’s eyes to ensure they remain relatively attentive to the road ahead. Meanwhile, Autopilot allows drivers to ignore almost everything so long as they’re willing to regain control of the vehicle when asked. The difference between the two is that the onus of safety remains slightly more with the driver with Super Cruise.  (Read More…)

vision 2.0 NHTSA Autonomous vehicles

Toyota wants to be a leader in the connected vehicle field and is encouraging all automakers to utilize dedicated short-range communications (DSRC) on all of vehicles sold in the United States — especially after it has already decided to do so with its own fleet. The brand has said it will be building talking cars by 2021. But they won’t talk in the same sense as a 1987 Chrysler New Yorker constantly reminding you that the door is ajar in a Speak & Spell voice, nor will they communicate with you like modern-day vehicles equipped with Amazon’s spyware intelligent personal-assistant service.

Instead, they’ll be talking to each other via a dedicated channel for vehicle-to-vehicle (V2V) communications. Toyota and Lexus intend to start equipping models with the technology in 2020, hoping to have it on most models by the following year. But it wasn’t the first to pitch the idea. The Federal Communications Commission allocated specific bandwidths for car chatter in 2017 and Cadillac has been talking about V2V for years.  (Read More…)
