Nissan ProPilot Assist Eases You Into Autonomous Cars

Nissan ProPilot Assist Prototype

I’ve been lucky enough to ride in a self-driving Toyota down a highway in Tokyo, cruise in an autonomous Hyundai drive in Las Vegas, and tested ZF’s auto-braking AI on a track in Austria.

Nissan ProPilot Assist Steering WheelWhat all of these futuristic rides had in common is that they were done in prototype vehicles, ones that are not something you can buy today. You can’t buy Nissan’s ProPilot Assist tech just yet, either – it will debut in the new Leaf later this year – but when it does arrive, it’ll be a few noticeable steps below the self-driving abilities being tested elsewhere in the industry.

You can tell that from the name. In the U.S., Nissan will call the technology ProPilot Assist, whereas in other markets it’ll simply be called ProPilot. The name change is due, in part, to the fact that Nissan wants to be totally clear that this system is “a ‘hands-on’ driver assist system rather than a ‘self-driving’ feature,” as a new press release says. Nissan also doesn’t want ProPilot Assist to be compared to what many drivers think of as the current gold standard of self-driving technology, Tesla’s Autopilot.

That said, ProPilot Assist is for sure the company’s first important step in autonomous drive technology. After introducing it in the new Leaf, Nissan will bring ProPilot Assist to other models in the U.S. (which ones and when, no one would tell us at a preview event for the U.S.-bound technology this week). ProPilot is already available in the Japanese market in the Serena minivan, and 60 percent of Serena buyers have opted for trim levels that include ProPilot.

Nissan Intelligent Mobility and ProPILOT Assist

So, what does ProPilot Assist actually do? Here’s where things don’t sound quite as impressive as the name implies.  If you’ve driven a recent vehicle with lane keep assist (LKA) technology and adaptive cruise control, then you’ve pretty much experienced the basics of ProPilot Assist.

When the new Leaf comes out, ProPilot Assist will be able to help the driver stay in a highway lane (as long as the lane markers are clear and identifiable by the car’s camera, which is supplied by Mobileye) and it will keep you safely spaced back from the car in front of you. The one way that ProPilot Assist differs from simple LKA and adaptive cruise is that it can help you out in traffic jams.

If the system is running and traffic slows, ProPilot Assist will make sure you keep up with all the car as they wind their way around an accident or construction or whatever is causing the problem. If things come to a complete stop, ProPilot Assist will stay engaged for three seconds. If you stop for more than that, you have to step on the accelerator or hit the “resume” button for the car to creep forward.

Obviously, the minimum speed for ProPilot Assist to work is zero miles per hour, and the top speed is 90 mph.

In other markets, the new Leaf will get ProPilot Park, but that option isn’t coming to the U.S. in the first year, since it wasn’t seen as a priority here. With parking more of a challenge in Europe and Japan, those markets got the engineering money and time to apply the self-parking ability first. As ProPilot evolves (see the graphic above) it will gain the ability to change lanes on the highway in two years, and assist with driving in city streets in four years thanks to over-the-air updates. All of these abilities will remain Level 2 on the autonomous driving scale, which means human input is required to keep things going.

During a drive on public roads in Michigan this week, I was able to test a version of ProPilot Assist that had been modded into a 2017 Rogue SUV. Despite the prototype situation, the system performed as promised, requiring minimal input from me to assure the car I hadn’t dozed off as it made the drive around metro Detroit about as easy as it can be without a fully self-driving car. Easing up the tensions of driving is Nissan’s main mission with ProPilot Assist, and it works as advertised. If Nissan wants to fully compete with the rest of the self-driving pack, though, it’ll need to advertise – and evolve – a better co-pilot.

Press Release:

Nissan ProPILOT AssistTM technology reduces the hassle of stop-and-go highway driving, ready for U.S. launch

  • Nissan enhances the driving experience by introducing technologies to make vehicles more intelligent, exciting and attainable partners
  • New ProPILOT AssistTM hands-on-wheel technology paves the way to the next level of autonomous driving
  • Unique Nissan Intelligent Mobility approach makes technology easy and intuitive – ProPILOT Assist features “two-button” activation

FARMINGTON HILLS, Mich. (July 21, 2017) – Earlier this week, for the first time on public roads in the U.S., Nissan put media behind the wheel to experience its ProPILOT Assist technology, which will be available to customers later this year. ProPILOT Assist reduces the hassle of stop- and-go driving by helping control acceleration, braking and steering during single-lane highway driving.

The ProPILOT Assist system, revealed at Nissan Technical Center North America (NTCNA), tuned specifically for U.S. roads and drivers – underwent more than 50,000 miles of development on roads across the entire United States. ProPILOT Assist combines Steering Assist and Intelligent Cruise Control for use in both heavy and flowing traffic situations. It is a “hands-on” driver assist system rather than a “self-driving” feature.

Nissan ProPILOT Assist

“Nissan is a technology pioneer and ProPILOT Assist sets a strong, consumer-focused foundation for fully autonomous vehicles of the future,” said Takeshi Yamaguchi, senior vice president, Research and Development, Nissan Technical Center North America, Nissan North America, Inc.

Nissan has plans to extend this technology to more models in Europe, Japan, China and the United States – with 10 models to be launched by 2020 by the Renault-Nissan Alliance.

How ProPILOT Assist Works

Tuned specifically for U.S. roads, ProPILOT Assist is designed to be more intuitive and user-friendly compared to other driver-assist technologies. It can potentially help lessen driver fatigue and create a more confident driving experience – especially for drivers who experience heavy highway traffic on a daily basis.

ProPILOT Assist utilizes a forward-facing camera, forward-facing radar, sensors and electronic control module to help the driver stay in the center of the driving lane and to maintain vehicle speed (set by the driver) or help maintain a gap to the preceding vehicle if the vehicle speed drops below the driver-set speed. It also can slow the vehicle to a complete stop and holds the vehicle during traffic jam conditions.

While providing steering assist, reducing the need for constant small steering adjustments, the driver’s hands must be on the steering wheel at all times. Hands-on detection is provided by the system’s steering torque sensor. If the driver only grips the steering system with a light touch, the warning system may activate, alerting the driver to apply more pressure or a tighter grip on the steering wheel.

Steering assist is cancelled in inclement weather if the windshield wipers are in the low or high position (if lane lines can be detected, the system can remain active when the wipers are in the intermittent mode or if the mist function is activated).
The driver’s input always takes priority, overriding the system when the steering wheel is turned or the turn signal is operated (steering assistance goes into a temporary standby mode). The system also goes into temporary standby mode when the accelerator pedal is pressed. And, the system’s Intelligent Cruise Control and lane keep assistance are both cancelled when the brakes are applied.

“ProPILOT Assist has the ability to track curving lanes, helping the driver stay centered in the lane as well as adjusting for various traffic flow conditions,” said Yamaguchi. “However, just as non- autonomous vehicles today, ProPILOT Assist requires the driver to remain engaged in the task of driving at all times – though the technology can reduce driver fatigue and increase driving enjoyment.”

About ProPILOT Assist

Nissan’s new ProPILOT Assist eases driver workload by reducing the amount of driver acceleration, steering and braking input under certain driving conditions. To activate the system, the driver simply pushes the blue ProPILOT Assist ON button, which is integrated into the right-side steering wheel spoke. Step two is to set the Intelligent Cruise Control when the desired speed is reached, as with a normal advanced cruise control system.

When lane markers are consistently detected, steering assist engages and the steering wheel/lane marker icons on the instrument panel turn green. Both right and left hand markers need to be detected by the front camera. Steering assist will engage or disengage depending on the visibility or presence of lane markers, though the Intelligent Cruise Control will remain active.
If the vehicle comes to a complete stop in a traffic jam situation for more than three seconds, the driver just presses the resume button or taps the accelerator pedal to begin moving again.

“ProPILOT Assist functionally enhances the ICC system, including stop, hold and start, while the steering assist’s lane centering helps keep the vehicle in the center of the lane,” added Yamaguchi. “Drivers who have experienced ProPILOT Assist always remark about the difference it makes, not realizing how many acceleration, steering and braking inputs they make under normal driving – and how much more enjoyable it is to have ProPILOT Assist help take care of it for them.”

    Sounds pretty good. About similar to Honda’s offerings and better than the Volt (and of course Bolt which doesn’t even have adaptive cruise). But it’s nothing compared to that high end systems like Tesla’s offer.

    Falr-to-middling. This seems to be becoming a theme with the LEAF.

  2. Iamwhoiam says:

    How is Tesla’s autopilot an industry gold standard?? Even Volvo can do better than Tesla in autonomous driving. Audi is probably number one right now, but JLR is not far behind.

    1. CLIVE says:

      Because Tesla has logged more miles and any other player and pushes updates out as they are able to learn and improve on AP.

      1. Someone out there says:

        Logging many miles doesn’t automatically make you good. Logging the same stretch of highway every day over several years adds very little new and valueable information to learn about. The problem with Tesla’s data collection that is done by customers is that they only engage it on stretches where they already know it works and what is the point of logging things it already know?

    2. CLIVE says:

      Because Tesla has logged more miles than any other player and pushes updates regularly as they learn and improve apon AP.

  3. AlnSqB says:

    If it has full acceleration, braking and steering authority in hardware, why not market it as an upgradable system? This is where the other makers are losing. I know if I buy this Nissan today, it will never get better beyond some dealer installed updates to fix bugs or airbag issues.

    The Tesla is built for the future. The OTA updates and the fact that the Nvidia module is modular and replaceable means that there is every chance that the Tesla I buy today will be able to reach full autonomy, even if it ends up requiring some upgrades.

    People will still buy the LEAF, but it’s a bit late to the party.

    1. John Ray says:

      Perhaps you didn’t read the article. It clearly says:

      “As ProPilot evolves (see the graphic above) it will gain the ability to change lanes on the highway in two years, and assist with driving in city streets in four years thanks to over-the-air updates.”

      1. Stimpy says:

        That is GREAT but I’ll remain skeptical until I see it happen on customer vehicles in the US. NADA is not keen on anything that lets owners avoid a visit to their friendly third-party dealer!

        Also how is this technically achieved? Do the cars all come with LTE modems as part of the ProPilot package? Is the data included for life? Does it do uploads for fleet learning like Tesla? Are USB updates ever required? Will it be fully automatic with no “software update request” needed from the customer?

        After all Nissan is the company had an inexcusably poor security model that it was discovered the *entire fleet* of Leafs could be remotely accessed just by knowing the VIN! See here: https://threatpost.com/total-recall-troy-hunt-breaks-down-his-nissan-hack/116497/

        1. John Ray says:

          Clearly, you know little about the Leaf.Leafs have always had a data modem and the data sharing has always been free. Each time you start the vehicle you are asked to opt in for data sharing with Nissan. So, yes they have fleet learning just like Tesla.

          As for your other strawmen, we will have to wait and see.
