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 will likely build PHEV batteries in China soon

It's a big week for batteries. Friday, Tesla will hold a big event at its Gigafactory in Reno, NV. But even in Michigan, there are things happening on the electrified automotive front. This was proven when GM invited journalists to its Brownstown Battery Assembly Plant today, highlighting the six different battery packs it makes for nine vehicles around the world (plus a tenth, coming to Asia, that has not yet been announced). During our tour, we learned a few interesting tidbits that we thought readers would like to hear: The Cadillac CT6 plug-in hybrid launches in China this fall before coming to the US next year. GM builds the battery packs in Michigan and ships them to China for final assembly in the PHEV. For now, this is all fine for GM to qualify for China's incentives for building green cars in the country. But, as Bill Wallace, GM's director of global battery systems, told AutoblogGreen, this could change thanks to the country's 'Made in China 2025' plan. The situation is "evolving," he said, and it's a safe assumption that GM will need to build packs in China some day. For the CT6 PHEVs that will be sold in the US, the batteries will make a round trip, since GM will only build the plug-in version in China. As for the range of the CT6 PHEV, that hasn't been announced, but since China offers incentives for vehicles that get at least 50 kilometers (31 miles), that's a likely target (the US range (UPDATE: GM did announce an expected range for the CT6 PHEV in the US at the LA Auto Show last fall, saying it would "travel approximately 30 miles on a full electric charge"). The battery pack in the CT6 is also a clunky box-type thing, totally unlike the near-elegant T-shape used in the Volt. This despite the fact that the guts of the two packs are similar. Both have 192 li-ion cells and weigh almost the same, but GM tuned the CT6 pack for acceleration instead of range, the way it did with the Volt's pack. Still, the main reason the packs are different is because the CT6 is a rear-wheel drive vehicle, and the tunnel that the Volt's pack uses is occupied by the driveshaft. Despite the highly touted second-gen Chevy Volt going on sale last year, GM still has the capacity to build battery packs for the old, first-gen model. This is because the company is legally required to be able to provide replacement packs for warrantied vehicles (for up to 10 years), and the second-gen packs don't fit into the first-gen vehicles.

Cadillac still planning for big things in China

Despite some hiccups, China remains the auto industry's great hope for new vehicle sales, with significant sales gains and a huge upside. Nowhere is that hope more fervent than at General Motors, which offers eight different marques in the Asian nation. China has been GM's single biggest market the last three years running, and is unlikely to give up that title anytime soon. Yet its premiere brand, Cadillac, has remained essentially stagnant, selling just 30,000 units in China last year. That's in a segment where sales of luxury vehicles has outpaced that of the larger Chinese market. So what gives?
According to Cadillac officials Autoblog spoke with in China this week at the Shanghai Motor Show, it's been a problem of product - they haven't had the right ones. Displacement taxation issues, import tariffs and currency fluctuations have all conspired to make the brand's products less appealing than they might otherwise have been. But GM is stepping on the gas with Cadillac, and executives are eyeballing 100,000 sales by 2016 - more than triple the Wreath and Crest's current volume. And the expectations for the brand only get more ambitious from there - they're shooting for 10 percent of the luxury market by 2020. Bob Socia, President of GM China, promises that there will be a new Caddy launched in the market each year from now through 2016 and most will be built in China. Characterizing the company's efforts to revive the brand's fortunes as a "relaunch" of sorts, Cadillac also figures to gain dealers as GM expands its sales outlet footprint westward.
New products like a made-in-China XTS sedan (with a market-specific 2.0-liter four-cylinder to avoid heavy displacement taxes) will help, and Socia hinted that the ATS sport sedan could be next in line for in-country production. The SRX crossover - currently the brand's best-selling model in China - will also likely get a long look for future local production when the next-generation model is introduced. In the meantime, Cadillac unveiled the Escalade ESV Hybrid (shown above) as its latest model addition to capitalize on the market's white-hot luxury SUV segment.
