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.

2020 Cadillac CT5 prototype shows off more lighting details

The elusive 2020 Cadillac CT5 luxury sports sedan has once again been spotted by a spy photographer. This time, we get to see it from all angles, whereas last time we only saw it from the front. It still has quite a bit of fake body work, and it's very clear Cadillac still hopes you'll think this is a Charger, from the big hood scoop to the fake full-width taillights. Digging past those misdirects, we can find some new details about the car. First, the car's front lighting has developed further. There are production-ready headlights fitted that appear to have some sort of LED illumination. These production lights also fit the shape we saw on the last prototype, so they'll end high up on the body, extending slightly horizontally toward the grille. There's still a section that extends back along the fender, seeming to bridge the gap between current Cadillacs and the Escala concept from which this car takes inspiration. Another addition are the vertical LED accent lights. This is another trademark feature of both current Cadillacs and the Escala, but they were absent from the last prototype we saw. We also get a look at some of the grille's details. Instead of slats, this CT5 has a plastic mesh of small rectangles. The pattern is reminiscent of brickwork. These photos also give us our first look at the back of the CT5. It looks like a fairly typical Cadillac. It's much more conservative than the front end. There are some angular cutouts in the bumper to allow exhaust gases out. The taillights have the current Cadillac look with the top curving over the rear fender. We can't tell if there will be a horizontal element like on the Escala, due to the fake lights. We're expecting the CT5 to be shown sometime next year in time for the 2020 model year. Odds are it will use off-the-shelf Cadillac engines including the turbocharged 2.0-liter four-cylinder, naturally aspirated 3.6-liter V6, and the twin-turbo 3.0-liter V6. Now that Cadillac has revealed its twin-turbo 4.2-liter V8, we'll be interested to see if that shows up in a future CT5-V.

Mary Barra thinks GM is a leader in autonomous tech

Saying General Motors is "among the leaders" in autonomous vehicle technology, CEO Mary Barra rapped about her company's driverless work in an interview with USA Today. Barra covered a number of topics, including well-known efforts, like Cadillac's upcoming Super Cruise technology, as well as hinting at "a lot of efforts that are confidential." "Things are moving quickly in autonomous [cars] because there's so many different pathways and the standards aren't even set. A lot of people can claim leads because people are making advancements in different areas," Barra said. "Next year we're going to have Super Cruise on one of our Cadillacs. On highways you'll be able to take your hands off the wheel and feet off the pedals – with a very creative way to make sure the driver is alert and involved in the driving process." As for those "confidential" efforts, feel free to speculate. GM has recently confirmed that it'd be running autonomous Volts at its Warren, MI tech center, which certainly indicates that the company is playing with much more than Super Cruise. GM will need to continue to embrace autonomous driving, owing to both traditional competitors like Toyota, as well as non-traditional opposition, like Google and Apple. Speaking of its competition from Silicon Valley, Barra was asked about two of the region's biggest names – Apple's Tim Cook and Tesla boss Elon Musk. "I have tremendous respect for Tim Cook, and I don't really think he needs advice from me," Barra told USA Today with a laugh. And when asked about Apple's future as a "viable competitor," she said, "I have no insights other than what I read in the papers. But it would be foolish for me not to assume that they're going to." As for Mr. Musk's openness about future products and how it contrasts with GM's relatively closed attitude, Barra also gave a chuckle. "I'm sure you would like me to say yes. I think we're fundamentally different. Look at our volume and look at the segments where we compete. His product line – his two products – his scale, it's completely different." The rest of Barra's interview is certainly worth a read, and includes talk about the Volkswagen diesel scandal, GM's changed relationship with the National Highway Traffic Safety Administration, and Uber.
