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.

Caddy XT4, Subaru STI Type RA, and blazin' Elon | Autoblog Podcast #553

On this week's Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Senior Editor Alex Kierstein and Green Editor John Snyder. We talk about time spent with the Cadillac XT4 and Subaru WRX STI Type RA. Then we get into other topics, including the death of the VW Beetle, our thoughts on the state of the Nissan 370Z, cameras replacing mirrors, the trouble with the Ford Focus Active, and Elon Musk blazing a fat blunt. We indulge in a little conversation about the process of writing about cars. Finally we help a listener choose their next EV in the "Spend My Money" segment.Autoblog Podcast #553 Get The Podcast iTunes – Subscribe to the Autoblog Podcast in iTunes RSS – Add the Autoblog Podcast feed to your RSS aggregator MP3 – Download the MP3 directly Rundown Cars we've driven: Cadillac XT4 and Subaru WRX STI Type RA RIP, VW Bug What's up with the Nissan 370Z?

Combine a self-driving car with V2V, and here's what happens

Transportation engineers have started laying the groundwork for a traffic world in which cars communicate with other cars and infrastructure like bridges and traffic lights. How about an environment in which cars talk to pretty much everything and everyone? In a preview of its offerings at the upcoming Consumer Electronics Show, Delphi Automotive will deploy just such a concept. Engineers have designed a system that communicates with traffic signals, street signs, pedestrians, cyclists, even to fry pits and parking garages along a driver's route. To date, engineers and researchers across the auto industry have focused on the technical and safety-oriented foundation of future vehicle-to-vehicle communications, which could help cars share information about everything from traffic tie-ups to upcoming road hazards. Beyond those building blocks, many have projected that V2V could also include more consumer-focused features. Delphi's system, dubbed V2Everything, might be the first that combines those sorts of features in a tangible package. At CES in Las Vegas, scheduled to begin the first week of January, company officials say they'll demonstrate in real-world conditions how V2V technology can be used in an autonomous vehicle to provide a range of critical safety information and leisure and convenience options for riders. The first V2V technology installed on a production car is slated to appear on the 2017 Cadillac CTS. "We imagine a world with zero traffic accidents," said Jeff Owens, Delphi's chief technology officer. "To get there, we will need a convergence of active safety, sensor fusion, connectivity platforms and advanced software." Such software might allow a vehicle to start searching for and reserving parking spots at a programmed destination long before arriving. It could allow riders to place their McDonald's drive-through order from the road and have the food ready for pickup along the route. For the drive itself, the Delphi-equipped car can stay updated on the status of traffic lights around Las Vegas, and can anticipate yellow and red lights. Using smart-phone technology, the car can detect pedestrians and cyclists that may otherwise be hard to see. It can send messages to friends or family to notify them of a driver's location. Some of those features have been available on third-party apps or individually developed by automakers. But this system marries them together in a single system that is tailored for use in self-driving cars.
