Super Cruise’s failsafes

Even though Super Cruise is not a fully autonomous system, it incorporates redundancies like those used in aircraft to ensure failsafe operation. Before taking off on a 700-mile, 11-hour test drive of the system — and putting my life in its hands without my hands on the wheel — I sat down with Daryl Wilson, lead development engineer for Super Cruise, to get a deep dive into the system and its critical safety backups. Autoblog: First, what makes Super Cruise different from similar systems? Wilson: The key differentiator for Super Cruise is hand-free driving. It's an industry first in that respect. Our competitors require the driver at minimum to place their hands on the wheel with some frequency to ensure that the car knows that the driver is there. We don't. Two key technologies allow us to do this. One is our Driver Attention System, which is our methodology for making sure the driver is engaged with the vehicle and engaged with the road. This is a driver assist system, not a fully autonomous system. So it requires driver engagement. We use an infrared camera that constantly monitors the driver's face to determine the direction they're looking. We're looking for the driver to be what we call on-road — not on the center stack, not to left or right or down. That's all done by the tracking of the face. We also track that the eyes are open. It's infrared because at night you need to illuminate the face and you can't be shining a light into the driver's face. Then we have our lidar mapping that provides a foundation for control and redundancy to ensure safe performance. Autoblog: How does the mapping act as a redundant feature? Wilson: This system is only for use on divided, controlled access highways. What I mean by a divided highway is something more than a painted line between you and oncoming traffic. Whether that's a grassy area in between the lanes or a concrete barrier, anything that separates you from oncoming traffic. That's the divided highway part. The controlled access part is entrance ramps and exit ramps. Not with roads that cross at grade, with traffic crossing at the same level. To do that we geofenced these roads to ensure that operation is only allowed in these conditions. We don't just recommend you use it there; we ensure that you only use it there.

GM executive chief EV engineer says reducing cost of plug-in vehicles is 'huge priority'

As we know, another major automaker investing heavily in electrified vehicles is General Motors, and it's doing things much differently than rivals BMW, Ford or Nissan. The Chevrolet Volt extended-range EV is a modest seller at its $35,000 sticker price but a huge hit with owners. The Chevy Spark BEV, still in limited availability, puts smiley faces on its owners and drivers. The just-introduced Cadillac ELR, a sharp-looking, fun-driving $76,000 luxocoupe take on the Volt's EREV mechanicals, has admittedly low sales expectations. With this interesting trio in showrooms and much more in the works, the third vehicle electrification leader I collared for an interview at Detroit's North American International Auto Show (see #1 and #2) was Pam Fletcher, GM's executive chief engineer, Electrified Vehicles. ABG: Why do your EREVs need four-cylinder power to extend their range when BMW's i3 makes do with an optional 650 cc two-banger? "We designed [the Volt and the ELR] to go anywhere, any time" - Pam Fletcher PF: I get that question all the time: why not something smaller? You don't really need that much. You use the electric to its ability, then you just need to limp. But we designed those cars to go anywhere, any time, and we don't want their performance to be compromised. If you're driving through the mountains, we don't want you to be crawling up grades, or to be limited on any terrain. So it's optimized to be able to travel literally the biggest grades and mountain roads around the globe at posted speeds. Because what if you can't? Another good reason: when the engine is on, you have to run it wide open throttle, max speed, most of the time. And while we can do a lot with acoustics, and the ELR has active noise cancelation, a small-displacement, low cylinder-count engine at high speed, high load all the time isn't something you want to live with. That's how we came up with the balance we did among the key factors of performance, NVH [noise, vibration and harshness] and range. ABG: Where you go from here? Is the range-extender engine due for an update? PF: We know and love the current Volt, and there is still a lot of acclaim about it, so we think it's a good recipe. But we are heavily in the midst of engineering the next-generation car, which I think everyone will love and be excited about.

Recharge Wrap-up: Cadillac CT6 Plug-In on sale in China, Oregon utilities spur EV adoption

The Cadillac CT6 Plug-In is now available in China. The luxury plug-in hybrid sedan uses a turbocharged 2.0-liter engine plus two electric motors, which give the car a 0-62 mph time of 5.4 seconds. Its liquid-cooled 18.4-kWh lithium-ion battery pack gives the car an all-electric range of 50 miles, with a total range of 581 miles. Cadillac offers a 200V charger with the CT6 Plug-In, which provides a full charge in less than five hours. Owners can check charging status remotely using OnStar or the MyCadillac app. The CT6 Plug-In is offered in two variants, priced at about $80,400 and $94,800. Read more from GM. Two Oregon utilities are launching a program to increase EV adoption. Portland General Electric (PGE) will build six charging locations, each with up to four dual-standard fast chargers. PGE will also build and operate charging sites for electric buses, freeing up money for Portland's TriMet transit agency to spend on the actual buses. Pacific Power will also build public EV chargers, and lower some electricity rates for operators. Both companies will also work to inform the public about the benefits of electric mobility. Oregon utilities are required to stop using coal by 2030, and use 50 percent renewable energy by 2040, which will make EVs even cleaner. Read more at Green Car Reports. Continental says a shift to EVs will cost its company jobs. The automotive parts supplier's CEO, Elmar Degenhart, says that while the company will need to cut production jobs, those will be offset at least in part by the creation of new positions related to electric mobility. "There is enough time to design the process such that the blow is softened and major pain can be avoided," says Degenhart. Some 30,000 jobs at Continental are tied to combustion engines.
