Crawling alongside on the congested freeway at about 35 mph in a Mercedes-Benz EQS 580, I used to be lower off by a semi, and later stopped simply within the nick of time to keep away from contact when the automobile in entrance of me abruptly panic-braked. Later, a fast evasive maneuver allowed me to narrowly miss two vehicles’ sudden lane modifications simply forward.
Though this would possibly sound like a typical, pulse-quickening day—or a great day, on the 405 in LA—and I used to be within the driver’s seat, from some authorized standpoints I wasn’t really driving.
Had an accident occurred in these hypothetical conditions, it could not have been my fault. So stated Mercedes-Benz, as they put together for the U.S. launch, maybe as quickly as subsequent 12 months, of a distinct type of automated driving system.
“Conditionally automated driving” is the important thing phrase actual right here, and it’s the explanation why Mercedes calls Drive Pilot an SAE Stage 3 system and never a Stage 2 system (or the confounding Stage 2 Plus).
Mercedes-Benz Stage 3 Drive Pilot
It’s an enormous step ahead. Regardless that Stage 3 Drive Pilot, doesn’t supply the high-speed operation and hands-free lane-change options of GM Tremendous Cruise, Ford BlueCruise or Tesla Enhanced Autopilot, it does utterly hand the duty of driving (and the duty) off to the automobile in some very particular situations, to present drivers some moments to themselves within the automobile—moments that may not be so nerve-wracking.
Stage 3 Drive Pilot is obtainable now in Europe within the S-Class and EQS, at an additional value of 5,000 euros and seven,430 euros ($5,100 and $7,600), respectively. For now, it applies solely on “appropriate motorway sections in Germany” as much as 37 mph, and requires one automobile forward to interact the system.
The system might be on LA freeways subsequent 12 months, although. Mercedes is aiming to get regulatory approval for its use beneath related situations in California and Nevada by the tip of the 12 months, and it’s ready to increase the identical authorized backing for legal responsibility ought to one thing go incorrect.
Constructing on adaptive cruise management—with loads of brains and sensing
It was straightforward to acclimate to how Drive Pilot operates, however nerve-wracking given the video-game-like price of potential mishaps a staff of specialists throwing at us on the check course. White lights on the 10 and a couple of positions of the steering wheel point out it’s able to be engaged, and inexperienced lights point out it’s at Stage 3.

So, if have an accident with a inexperienced mild on, it’s not your fault; it’s the producer’s fault.
Drive Pilot steers to maintain the car in its lane and in any other case features as an adaptive cruise management system, following autos forward. It’s hyper-aware, although, and able to carry out evasive maneuvers and/or abrupt braking.
Mercedes-Benz EQS – sensors utilized by Drive Pilot
The system builds on what’s included in these fashions’ Driving Help Package deal—a Stage 2 system—but it surely provides a lidar unit in entrance, extra cameras, and ultrasound and moisture sensors. One of many most important functions of the additional rear digicam is to detect emergency lights, and the system faucets into the inside microphone to detect the siren.
One other digicam retains a watch on the motive force. That’s not foolproof, although. At 6-foot-6, I lately drove an EQS with the Driver Help Package deal on U.S. highways and had bother getting my seat and steering wheel within the correct place, because the system repeatedly requested me to readjust.

However Drive Pilot’s software program is way extra superior. Redundancy within the steering, braking, wheel pace sensors, and extra—like a complete second set of wiring for the steering—helps ensure that even when car programs fail, Drive Pilot can present a 10-second handoff. The system carries two separate computational layers and has, extra computational and sensing smarts than an A380 Airbus, based on Matthias Struck, a senior security engineer at Mercedes-Benz, whereas drawing lower than 50 watts of energy. That’s much less vitality thanAudi’s earlier Visitors Jam Help, which had been U.S.-bound for the A8 however by no means arrived.
10 lengthy seconds of handoff
If the system encounters a scenario by which it desires handy off management to the motive force for any cause. It first points a immediate requiring an “OK” click on of the left steering-wheel toggle. Then three seconds later there’s a haptic buzz of the seat belt, adopted by a second buzz a number of seconds later. Past 10 seconds, it is going to slowly convey the automobile to a cease if there’s nonetheless no response.

The ten-second handoff is an enormous deal, requiring extra {hardware} not only for redundancy however precision and accuracy. A high-precision GPS system is the inspiration, digitally fused with anonymized knowledge for lidar, digicam, radar, and ultrasound, plus a digital HD map with info on street geometry and extra. With it, Mercedes claims accuracy to the centimeter as an alternative of the meter.
Mercedes emphasizes that Drive Pilot hasn’t been developed shortly. Along with years of engineering, it’s concerned knowledge safety officers, ethics specialists, legal professionals, and varied compliance ranges. Roughly eight years of information went into the mapping of eventualities, together with varied research on what works and what doesn’t for the handoff of management again to the motive force.
The system all the time makes use of a number of strategies to verify it’s on the correct roadway, including in digicam and lidar knowledge, in addition to street marker info, and it doesn’t ever go solely by GPS, because it’s possible that might be manipulated.
Why Mercedes sees Stage 3 as an enormous step ahead
Within the 5 SAE ranges of driving automation, Stage 3 is conditional automation. Many automakers have stated that they will skip Stage 3 automation as a result of they consider the situations are imprecise in interpretation, and it could be harmful to instantly hand all driving features again to a human that is not required to concentrate to the street.
However for Mercedes, these situations are fairly easy: The driving force has to remain in place and monitor the system. In place means you’ll be able to’t recline greater than about 4 inches out of your regular driving place. You’re allowed to take your fingers off the steering wheel, to take your eyes off the street, and even to show your head to the facet. However you’ll be able to’t take a nap.
Mercedes Stage 3 Drive Pilot examined
As I found in my brief closed-course test-drive, some flexibility is constructed into the system. As an illustration, so long as you’re belted, it’s OK to look again to a baby within the again seat for 3 to 5 seconds.
You’ll be able to push it too far, although. After consulting with the engineer within the passenger seat, I closed my eyes utterly, and simply eight or 9 seconds later a immediate popped up asking me to verify I used to be nonetheless alert. I ignored it, which quickly began the 10-second countdown towards disengagement.
However the legal responsibility shifts the second you allow your seat or shift out of place. “If in case you have Drive Pilot engaged however depart your seat, it’s your fault since you are accountable to sit down in your seat and take over management if the automobile prompts you to take action,” stated Struck.
Accountability, taken critically
Mercedes retains monitor of all of this in a number of alternative ways. Firstly, there’s a tool that data when Drive Pilot is activated and when it’s deactivated. That is anonymized and saved within the automobile however not uploaded wherever. There’s additionally incident knowledge, which is car-specific ought to one happen, and the corporate has a particular staff watching the market and following knowledge that’s created with each incident or every time there’s a full braking occasion.

Prospects should comply with share this knowledge. As a part of the certification course of within the U.S., house owners will probably be required to completely watch a video on the infotainment display screen, and make sure. It’ll even be accessible on Mercedes me, the model’s digital platform that features a smartphone app.
“From a technical standpoint we might be capable of go perhaps sooner, perhaps additionally carry out a lane change, however that’s a subject for the longer term,” stated Struck, who known as the system “completely suited” to the 60-km/h pace, because it goals to ascertain belief for patrons.
The system is now tuned for the laws in Germany, which require that the car keep in a single journey lane. The car isn’t allowed to remain on this mode if it wants to depart the lane for evasive causes, and it’s not allowed to do lane-changes.
Mercedes-Benz Stage 3 Drive Pilot
That explains why, once I was lower off by a collection of autos moderately than one and Drive Pilot3 had steered barely to the facet—a bit out of the journey lane—to keep away from contact, it determined to move off management to me. With only one automobile darting at a tangent in entrance of me, it had as an alternative been capable of blip the brakes and remained engaged.
For particularly sturdy braking or a powerful lateral maneuver, there’s additionally a takeover request, although.
Carrying Drive Pilot over to undisciplined American lanes
Issues are fairly totally different between the Autobahn and LA freeways. The lane limitations may not apply so strictly within the U.S., the place lane markings are a significant hurdle as a result of they’re inconsistent and typically nonexistent. One engineer additionally known as the intermittent reflectors utilized in some American highways “very difficult” as they create a necessity to show the system a brand new set of situations.
Mercedes says it at the moment has check drivers and check routes round Los Angeles for Drive Pilot To date it’s solely educated engineers and test-drivers, not prospects.
Drive Pilot might not be as glamorous as a system that performs lane modifications and might make city journeys with the motive force’s fingers principally off the steering wheel, but it surely’s a totally developed system you’ll be able to actually belief on a congested freeway. You’re not a beta-tester.
In a slog of slogs, just like the 405, you would possibly be capable of let your thoughts wander. Slightly bit. Simply don’t shut your eyes.
