• Ford Conducts First Ever Snow Tests Of Autonomous Vehicles

As automakers all over the world continue to race towards autonomous driving technology, one company has beaten all others in testing driverless cars in snowy conditions. Not that it’s an achievement of some sort, but Ford has done it, becoming the first automaker to do so since Google, another company that’s already testing autonomous vehicles in the snow, isn’t technically an automaker…yet.

In any event, Ford said that it’s been running sensor tests for more than a year now and these tests have led to prototypes of its driverless cars to drive by themselves in a controlled, snowy environment. So how exactly was Ford able to become the first automaker to do this? According to the company, it recalibrated an existing technology among driverless cars. The technology is called Light Detection and Ranging sensors, or LIDAR for short. These sensors are installed in a handful of sections in the body of the car to help build a detailed view of the environment around the car. They function just like radar in their ability to rapidly fire laser lights away from the car and measure how much light is reflected back. But, since these sensors don’t work well in snowy conditions, Ford reprogrammed the sensors to instead detect landmarks that are above the ground, including road signs, traffic lights, and even buildings. Once these landmarks are detected, the car is able to compare this info to a high-resolution map of the road that it already has stored in its computer, allowing the car to navigate the road by itself even during times when road visibility are at its worst.

You could say that it’s an achievement by Ford, and in some ways, it is. But, autonomous driving cars being able to navigate around snowy conditions is just another piece to this entire puzzle that Ford and a lot of other automakers are racing to finish first. It’s nice to see that the Blue Oval is putting in the work to ensure that it crosses that line first.

Why it matters

This isn’t entirely surprising considering that a lot of companies are all on the same boat as Ford. They’re all doing their own research and development of their own autonomous driving tech, so at some point, somebody’s going to be the first at achieving a breakthrough of some sort. It just happened to be Ford.

I’m not saying this because I’m dismissing Ford’s achievement, because it really is a big step in finally bringing autonomous driving technology to life. It goes to show that the American automaker is going all-in on this tech as it should. Judging by how a lot of companies are doing the same thing, it was very important for Ford to be the first to get a driverless car to navigate around a model city built by the University of Michigan in snowy conditions. Being the first means other companies will look at your model and try to replicate it with their own tech. This gives Ford the small edge of pursuing other aspects of the technology as other companies try to keep up.

I’m excited to see what lies ahead for Ford and the future of autonomous driving as a whole. This technology has gone past the point of being a fad that will eventually die down. It’s a real thing that’s really shaping up to be the future of the industry. Whether it’s automakers like Ford, Tesla, Toyota, or tech giants like Google or Uber, everybody has pushed their chips into the center of the table. In a lot of ways, it solidifies one of the most popular sayings within the auto industry: the race for innovation never ends.

Kirby’s first exposure into the world of automobiles happened when he caught Knight Rider on television as a five-year old boy. David Hasselhoff didn’t leave much of an impression on him (that happened later on in Baywatch), but KITT certainly did. To this day, Kirby remains convinced that he will one day own a car with the same ‘spirit’ as the original KITT (not the 2008 monstrosity). He doesn't know when that will be, but until then, he’s committed to expressing his love for KITT, and all cars for that matter, here at TopSpeed.  Read full bio

Ford is conducting the industry’s first autonomous vehicle tests in snow-covered environments – a major step in the company’s plan to bring fully autonomous vehicles to millions of customers worldwide.

Unlike other major automakers and technology companies, which have tested autonomous vehicle technology only in dry, mostly sunny climates, Ford knows the future of autonomous driving cannot rely on ideal conditions.

“It’s one thing for a car to drive itself in perfect weather,” said Jim McBride, Ford technical leader for autonomous vehicles. “It’s quite another to do so when the car’s sensors can’t see the road because it’s covered in snow. Weather isn’t perfect, and that’s why we’re testing autonomous vehicles in wintry conditions – for the roughly 70 percent of U.S. residents who live in snowy regions.”

Ford’s winter weather testing takes place in Michigan, including at Mcity – a 32-acre, full-scale simulated real-world urban environment at the University of Michigan.

Fully autonomous driving can’t rely on GPS, which is accurate only to several yards – not enough to localize or identify the position of the vehicle. And it’s key that an autonomous vehicle knows its precise location, not just within a city or on a road, but in its actual driving lane – a variation of a few inches makes a big difference.

LiDAR, on the other hand, is much more accurate than GPS – identifying the Fusion Hybrid’s lane location right down to the centimeter. LiDAR emits short pulses of laser light to precisely allow the vehicle to create a real-time, high-definition 3D image of what’s around it.

In ideal weather, LiDAR is the most efficient means of gathering important information and metadata – underlying information about the data itself – from the surrounding environment, sensing nearby objects and using cues to determine the best driving path. But on snow-covered roads or in high-density traffic, LiDAR and other sensors such as cameras can’t see the road. This is also the case when the sensor lens is covered by snow, grime or debris.

Undaunted by this challenge, Ford and University of Michigan technologists began collaborating toward a solution that would allow an autonomous vehicle to see on a snow-covered road.

How snow autonomy works
To navigate snowy roads, Ford autonomous vehicles are equipped with high-resolution 3D maps – complete with information about the road and what’s above it, including road markings, signs, geography, landmarks and topography.

“Maps developed by other companies don’t always work in snow-covered landscapes,” said Ryan Eustice, associate professor at University of Michigan college of engineering. “The maps we created with Ford contain useful information about the 3D environment around the car, allowing the vehicle to localize even with a blanket of snow covering the ground.”

An autonomous vehicle creates the maps while driving the test environment in favorable weather, with technologies automatically annotating features like traffic signs, trees and buildings. When the vehicle can’t see the ground, it detects above-ground landmarks to pinpoint itself on the map, and then subsequently uses the map to drive successfully in inclement conditions.

“The vehicle’s normal safety systems, like electronic stability control and traction control, which often are used on slippery winter roads, work in unison with the autonomous driving software,” said McBride. “We eventually want our autonomous vehicles to detect deteriorating conditions, decide whether it’s safe to keep driving, and if so, for how long.”

A pioneer in autonomy
Winter driving still presents a host of challenges, but Ford’s testing marks an important achievement on the road to autonomous driving. That road goes back roughly a decade, to the first-generation autonomous vehicle from Ford – a LiDAR-equipped F-250 Super Duty.

In 2013, Ford launched its second-generation autonomous vehicle platform, a Fusion Hybrid sedan using more advanced LiDAR sensors. This past summer, Ford transitioned its fully autonomous vehicle development program from the research to advanced engineering phase, the second of three phases before entering production.

Earlier this month, Ford announced it is taking the next step – tripling its fully autonomous development fleet to 30 vehicles being tested on roads and test tracks in California, Arizona and Michigan. This makes the company’s fully autonomous vehicle fleet the largest of all automakers. These third-generation autonomous vehicles continue to be based on a Fusion Hybrid sedan now featuring the first auto-specific LiDAR sensor capable of handling different driving scenarios – thanks in part to its longer range of around 200 meters.

Building on more than a decade of Ford autonomous vehicle research, this advancement is a key element of Ford Smart Mobility – the plan to take Ford to the next level in connectivity, mobility, autonomous vehicles, the customer experience, and data and analytics.
