Lucid Motors’ all-electric Air will have 32 sensors, including lidar to support hands-free highway driving

Lucid Motors is loading up its first electric vehicle with hardware — dozens of sensors, a driver monitoring system and an Ethernet-based architecture — for an advanced driver assistance system that aims to match and even surpass its rivals.

There will be 32 sensors in all, according to Lucid, which has branded its advanced driver assistance system DreamDrive. The total number isn’t what matters. The type and location — and of course, the software — does. For now, Lucid is just providing details on the hardware. 

The Air, which is set to debut September 9, will come with one lidar, radars, cameras and ultrasonic sensors. Lidar — the light detection and ranging radar that measures distance using laser light to generate a highly accurate 3D map of the world around the car — is a noteworthy inclusion. The sensor is typically used on autonomous vehicles, not the production cars, trucks and SUVs that consumers will buy and drive. Lucid said its long-range lidar sensor will be placed in the front of the vehicle.

There is a small and growing list of automakers that have plans to include lidar in their production vehicles as well. Volvo revealed in May plans to start producing vehicles in 2022 that are equipped with lidar and a perception stack — technology developed by Silicon Valley startup Luminar that the automaker will use to deploy an automated driving system for highways. 

The number of radar sensors and their location is also a standout feature. Lucid will have five radars in all, one located in front to augment the capabilities of the lidar. The other four will be located on the four corners of the vehicle. This gives the Air 360 degrees of radar coverage. Tesla, which has an advanced driver assistance system that is widely considered to be the most or among the most capable on the market today, has eight cameras, 12 ultrasonic sensors and just one radar. Tesla vehicles do not have lidar.

Inside the vehicle, will be a driver monitoring system with a dedicated camera. Lucid Motors didn’t reveal much about its DMS. However, it’s likely to operate similarly to GM’s hands-free system known as Super Cruise. Eugene Lee, the senior director of ADAS and autonomous driving at Lucid Motors, formerly worked on GM’s Super Cruise. 

Underlying all of this will be a high-speed Ethernet Ring, which Lucid describes as a unique cornerstone of advanced electric architecture. Automakers have been moving towards Ethernet technology for several years now in an effort to create a centralized network that simplifies the deployment of advanced features. Lucid said its ring, and not linear, design is what allows for a redundant platform for functions such as steering, brakes, sensors and even power sources. The system also allows for over-the-air software upgrades, an important feature (popularized by Tesla) that gives Lucid the ability to improve the ADAS over time. 

All this hardware will come standard on the first iteration of the Lucid Air, a pricier and more exclusive launch version called the Dream Edition. Lucid is sourcing its hardware system from several large suppliers, including Bosch, Continental and Here. The automaker said it integrates the hardware in house. 

The aim is for all of this hardware to support high functioning driver assistance features, eventually including hands-free automated highway driving. This ADAS package will not only offer Level 2 features, but is also Level 3 ready, according to Lee. There are five levels of automation under SAE’s definition. Level 2, is in which two primary functions are automated, and still have a human driver in the loop at all times. Level 3 takes that up a notch and is considered conditional automation in geofenced areas such as highways. Driver must still be prepared to intervene with Level 3.

Lucid said its DreamDrive tech will support 19 safety, driving and parking assist features that will be available as soon as the Air rolls off the assembly line. The automaker plans to add eight more features at a later date.

Lucid said the system will include safety features such as surround view monitoring, blind spot display, cross traffic protection that informs the driver of vehicles perpendicular to them, traffic sign recognition, automatic emergency braking and alerts for distracted or drowsy drivers. 

The driving assistant features will include adaptive cruise and lane centering for highway driving, headlight assist and an alert that tells the driver when standstill traffic has started to move again. It will also offer what Lucid describes as autonomous parking.

Uber co-founder Garrett Camp steps back from board director role

Uber co-founder Garrett Camp is relinquishing his role as a board director and switching to board observer — where he says he’ll focus on product strategy for the ride hailing giant. Camp made the announcement in a short Medium post in which he writes of his decade at Uber: “I’ve learned a lot, and realized that I’m most helpful when focused on product strategy & design, and this is where I’d like to focus going forward.” “I will continue to work with Dara [Khosrowshahi, Uber CEO] and the product and technology leadership teams to brainstorm new ideas, iterate on plans and designs, and continue to innovate at scale,” he adds. “We have a strong and diverse team in place, and I’m confident everyone will navigate well during these turbulent times.” The Canadian billionaire entrepreneur signs off by saying he’s looking forward to helping Uber “brainstorm the next big idea”. Camp hasn’t been short of ideas over his career in tech. He’s the co-founder of the web 2.0 recommendatio...

Drone crash near kids leads Swiss Post and Matternet to suspend autonomous deliveries

A serious crash by a delivery drone in Switzerland have grounded the fleet and put a partnership on ice. Within a stone’s throw of a school, the incident raised grim possibilities for the possibilities of catastrophic failure of payload-bearing autonomous aerial vehicles. The drones were operated by Matternet as part of a partnership with the Swiss Post (i.e. the postal service), which was using the craft to dispatch lab samples from one medical center for priority cases. As far as potential applications of drone delivery, it’s a home run — but twice now the craft have crashed, first with a soft landing and the second time a very hard one. The first incident, in January, was the result of a GPS hardware error; the drone entered a planned failback state and deployed its emergency parachute, falling slowly to the ground. Measures were taken to improve the GPS systems. The second failure in May, however, led to the drone attempting to deploy its parachute again, only to sever the line...

How the world’s largest cannabis dispensary avoids social media restrictions

Planet 13 is the world’s largest cannabis dispensary. Located in Las Vegas, blocks off the Strip, the facility is the size of a small Walmart. By design, it’s hard to miss. Planet 13 is upending the dispensary model. It’s big, loud and visitors are encouraged to photograph everything. As part of the cannabis industry, Planet 13 is heavily restricted on the type of content it can publish on Instagram, Facebook and other social media platforms. It’s not allowed to post pictures of buds or vapes on some sites. It can’t talk about pricing or product selection on others.   View this post on Instagram   A post shared by Morgan Celeste SF Blogger (@bayareabeautyblogger) on Jan 25, 2020 at 7:54pm PST Instead, Planet 13 encourages its thousands of visitors to take photos and videos. Starting with the entrance, the facility is full of surprises tailored for the ‘gram. As a business, Planet 13’s social media content is heavily restricted a...
