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.

Safety group pans GM’s new Marketplace in-dash shopping

When it comes to our cars, is the Internet of Things a godsend? Or a hidden menace that will create more problems than it will solve? On the same day General Motors announced it will equip newer-model cars with its in-dash Marketplace e-commerce app, a prominent safety group was shooting it down. National Safety Council President Deborah Hersman tells Bloomberg the technology will only contribute to distracted driving and hurt efforts to stem the tide of rising auto fatalities, which grew 5.6 percent to more than 37,000 in the U.S. in 2016. The National Highway Traffic Safety Administration says distracted driving was responsible for 3,477 fatalities and 391,000 injuries in 2015, the most recent year for which it has data. "There's nothing about this that's safe," Hersman told Bloomberg. "If this is why they want WiFi in the car, we're going to see fatality numbers go up even higher than they are now." Marketplace, developed with IBM, will allow drivers — or more often, one hopes, their passengers — to order coffee or food, find gas stations and reserve hotel rooms from their dashboard screens. The technology is set to be uploaded automatically to nearly 1.9 million GM vehicles model-year 2017 and later that are equipped with WiFi hotspots and compatible systems. By the end of 2018, about 4 million Chevrolet, Buick, GMC and Cadillac vehicles will be equipped with Marketplace. The app will debut with a limited number of participating retailers, including TGI Fridays, Shell, Exxon Mobil and Starbucks, with more likely to join later. Online retail giant Amazon is also partnering with automakers such as Ford to bring e-commerce capabilities inside the car through its Alexa personal assistant. While convenience is nice, one other thing is becoming clear as the IoT wedges its way into our cars: It's taking aim at some decidedly first-world problems.Related Video: Image Credit: GM Buick Cadillac Chevrolet GM GMC Technology Infotainment in-car entertainment marketplace e-commerce

Cadillac president reveals XTS sedan refresh, flagship vehicle plans

Update: The second paragraphed has been changed from the original text to make it clear that de Nysschen, not Autoblog , claimed the report by The Detroit Bureau is inaccurate. Cadillac has been on a tear ever since the automaker poached Johan de Nysschen from Infiniti, becoming a more profitable automaker while delving deeper into the luxury market. While some reports indicate that Cadillac may be limiting its lineup, de Nysschen just put everything out in the open. In the comment section of an article by The Detroit Bureau that claimed Cadillac would cut its lineup down, de Nysschen stated the report was inaccurate and outlined the automaker's future. The Cadillac CEO wrote "Some of what you report is correct, some incorrect, most is conjecture." A Cadillac spokesperson confirmed that de Nysschen did write the comment, but did not comment on any of the details. The Detroit Bureau's Paul Eisenstein told Autoblog that he stands behind the information in the report. In any case the most interesting tidbit in de Nysschen's comment is the major refresh for the Cadillac XTS. The news directly contradicts previous reports that indicated the XTS would be killed off by 2019. In Cadillac's pursuit to add some space between it and GM, the XTS was expected to get the axe in favor of more profitable vehicles. The sedan, which was introduced in 2012, shares its underpinnings with the latest generation of the Chevrolet Impala. To the contrary, Nysschen stated that "We ARE planning a major refresh for XTS." What the major refresh will bring the aging sedan is still a mystery, but the vehicle isn't dying. The move to keep the XTS in its lineup is a bit of a surprise as Cadillac has filled its lineup with track-oriented sports cars, rear-wheel-drive sedans, and extravagant crossovers. The boat-like XTS with its front-wheel-drive layout and available all-wheel-drive system sticks out like a sore thumb, even if it were to receive a major overhaul. The only real explanation is that Cadillac hopes the vehicle will still appeal to its old-school customers that are unwilling to compromise interior space and ride quality. In our most recent review of the XTS, we thought the luxurious sedan was a great long-distance cruiser, but not a talented sports car – no surprises there. It's unlikely that Cadillac will focus on driving pleasure with the refreshed XTS, focusing instead on pure comfort and luxury.
