Crawling alongside on the congested freeway at about 35 mph in a Mercedes-Benz EQS 580, I used to be reduce 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 all of the sudden panic-braked. Later, a fast evasive maneuver allowed me to narrowly miss two automobiles’ 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 truly driving.
Had an accident occurred in these hypothetical conditions, it could not have been my fault. So stated Mercedes-Benz, as they prepare for the U.S. launch, maybe as quickly as subsequent yr, of a unique 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 Degree 3 system and never a Degree 2 system (or the confounding Degree 2 Plus).
Mercedes-Benz Degree 3 Drive Pilot
It’s a giant step ahead. Despite the fact that Degree 3 Drive Pilot, doesn’t provide the high-speed operation and hands-free lane-change options of GM Super Cruise, Ford BlueCruise or Tesla Enhanced Autopilot, it does utterly hand the duty of driving (and the accountability) off to the automobile in some very particular situations, to provide drivers some moments to themselves within the automobile—moments that may not be so nerve-wracking.
Degree 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 yr, although. Mercedes is aiming to get regulatory approval for its use below comparable situations in California and Nevada by the top of the yr, and it’s ready to increase the identical authorized backing for legal responsibility ought to one thing go mistaken.
Constructing on adaptive cruise management—with a variety 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 take a look at course. White lights on the 10 and a pair of positions of the steering wheel point out it’s able to be engaged, and inexperienced lights point out it’s at Degree 3.
Mercedes-Benz Degree 3 Drive Pilot
So, if have an accident with a inexperienced gentle on, it’s not your fault; it’s the producer’s fault.
Drive Pilot steers to maintain the automobile in its lane and in any other case features as an adaptive cruise management system, following automobiles 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 Degree 2 system—but it surely provides a lidar unit in entrance, further cameras, and ultrasound and moisture sensors. One of many major 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 an eye fixed on the driving force. That’s not foolproof, although. At 6-foot-6, I not too long ago drove an EQS with the Driver Help Package deal on U.S. highways and had hassle 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 much extra superior. Redundancy within the steering, braking, wheel pace sensors, and extra—like a whole second set of wiring for the steering—helps make it possible for even when automobile techniques 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, in line with Matthias Struck, a senior security engineer at Mercedes-Benz, whereas drawing lower than 50 watts of energy. That’s much less power thanAudi’s earlier Site 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 state of affairs wherein it desires at hand off management to the driving force for any purpose. 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 just a few seconds later. Past 10 seconds, it’s going to slowly deliver the automobile to a cease if there’s nonetheless no response.

The ten-second handoff is a giant deal, requiring further {hardware} not only for redundancy however precision and accuracy. A high-precision GPS system is the muse, digitally fused with anonymized information for lidar, digicam, radar, and ultrasound, plus a digital HD map with data on highway geometry and extra. With it, Mercedes claims accuracy to the centimeter as a substitute of the meter.
Mercedes emphasizes that Drive Pilot hasn’t been developed rapidly. Along with years of engineering, it’s concerned information safety officers, ethics specialists, attorneys, and varied compliance ranges. Roughly eight years of knowledge 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 driving force.
The system all the time makes use of a number of strategies to ensure it’s on the right roadway, including in digicam and lidar information, in addition to highway marker data, and it doesn’t ever go solely by GPS, because it’s possible that might be manipulated.
Why Mercedes sees Degree 3 as a giant step ahead
Within the 5 SAE levels of driving automation, Degree 3 is conditional automation. Many automakers have stated that they will skip Degree 3 automation as a result of they imagine the situations are imprecise in interpretation, and it could be harmful to right away hand all driving features again to a human that is not required to concentrate to the highway.
However for Mercedes, these situations are fairly easy: The driving force has to remain in place and monitor the system. In place means you may’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 highway, and even to show your head to the facet. However you may’t take a nap.
Mercedes Degree 3 Drive Pilot examined
As I found in my brief closed-course test-drive, some flexibility is constructed into the system. For example, 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 possibly can 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 substantiate 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. “You probably have Drive Pilot engaged however go away your seat, it’s your fault since you are accountable to take a seat in your seat and take over management if the automobile prompts you to take action,” stated Struck.
Accountability, taken significantly
Mercedes retains observe of all of this in just a few alternative ways. Firstly, there’s a tool that information when Drive Pilot is activated and when it’s deactivated. That is anonymized and saved within the automobile however not uploaded anyplace. There’s additionally incident information, which is car-specific ought to one happen, and the corporate has a particular staff watching the market and following information that’s created with each incident or every time there’s a full braking occasion.

Clients should comply with share this information. As a part of the certification course of within the U.S., homeowners shall be required to totally watch a video on the infotainment display, and ensure. It’ll even be out there on Mercedes me, the model’s digital platform that features a smartphone app.
“From a technical standpoint we might be capable of go possibly sooner, possibly additionally carry out a lane change, however that’s a subject for the longer term,” stated Struck, who referred to as the system “completely suited” to the 60-km/h pace, because it goals to determine belief for patrons.
The system is now tuned for the laws in Germany, which require that the automobile keep in a single journey lane. The automobile isn’t allowed to remain on this mode if it wants to go away the lane for evasive causes, and it’s not allowed to do lane-changes.
Mercedes-Benz Degree 3 Drive Pilot
That explains why, after I was reduce off by a sequence of automobiles slightly 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 go off management to me. With only one automobile darting at a tangent in entrance of me, it had as a substitute been in a position to 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 completely 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 serious hurdle as a result of they’re inconsistent and typically nonexistent. One engineer additionally referred to 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 present has take a look at drivers and take a look at routes round Los Angeles for Drive Pilot To date it’s solely educated engineers and test-drivers, not clients.
Drive Pilot might not be as glamorous as a system that performs lane modifications and might make city journeys with the driving force’s fingers largely off the steering wheel, but it surely’s a totally developed system you may really 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. A bit bit. Simply don’t shut your eyes.
