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.

Saturn Vue ignition switch leads to new group of GM recalls totaling 312k

General Motors has another spate of recalls to announce. This time they cover 312,280 vehicles worldwide, including 269,041 of in the US, in a total of six campaigns. In 2014, the automaker has recalled 29,079,765 vehicles worldwide, with 25,754,356 of those in the US.
The largest among them covers 215,243 units of the Saturn Vue from 2002-2004 model years worldwide, 202,115 in the US. It's possible for the for the key to be removed even when the ignition isn't in the OFF position. The company knows of two crashes and one injury caused by this problem. Dealers are checking the parts and replacing the ignition cylinder and key set, if necessary.
Next is 72,826 models worldwide (48,059 vehicles in the US) of the 2013 Cadillac ATS four-door sedan, 2013 Buick Encore and 2013 Chevy Trax in Canada. It's possible that the for lap belt pretensioner to retract but not to lock, which could increase occupant movement during a crash. Both front, outboard lap belt pretensioners are being replaced, and a stop-sale is in effect on unsold models until the problem is repaired. There are no known crashes or injuries, though.

Cadillac will build a Tesla fighter, sources say, as GM's leading EV brand

WASHINGTON — Cadillac is expected to become General Motors' lead electric vehicle brand as the largest U.S. automaker gears up to introduce a new model under that luxury marquee to challenge Tesla, two people briefed on the matter said Thursday. GM is set to announce Friday as part of an investor update that a Cadillac will be the first vehicle based on its forthcoming "BEV3" platform, the people said. The vehicle platform is the basis for vehicle underpinnings, including the battery system and other structural and mechanical parts. GM is not expected to disclose on Friday additional details, including precisely when the Cadillac EV will be built, whether it will be a crossover or sedan, or where it will be assembled, the sources said. A GM spokesman declined to comment. GM had previously focused on making electric vehicles under its mass market Chevrolet brand, including its plug-in Chevrolet Volt and battery electric Bolt. GM announced last year it was ending production of the plug-in Volt as well as a low-selling plug-in Cadillac CT6, even as it moved to boost EV spending. GM said in November as part of its restructuring efforts it was doubling resources for electric and autonomous vehicle programs over the next two years. Last month, two Ohio senators asked GM to commit to building all future electric vehicles for U.S. buyers within the country. GM said in 2017 it planned by 2021 to introduce a new dedicated flexible electric vehicle architecture and an advanced battery system to support the development of at least 20 new models in the United States and China. GM said in 2017 that a new electric vehicle platform in 2021 will serve as a base for at least nine derivatives, ranging from a compact crossover to a large seven-passenger luxury sports utility vehicle and a large commercial van. Johan de Nysschen, who was then Cadillac's president, told Reuters at the Detroit Auto Show in January 2018 the luxury brand will play a "central role" in GM's electrification strategy, including China. He added that Cadillac would be "at the forefront" of rolling out new electric vehicles in the United States and China. He left GM in April. This week, GM said Cadillac sales in China rose 17.2 percent in 2018, surpassing 200,000 units for the first time. GM Chief Executive Mary Barra has said that GM aims to sell 1 million electric vehicles a year by 2026, many of them in China, which has set strict production quotas on such vehicles.
