Mercedes-Benz Co-Operative Car concept uses turquoise LEDs to 'talk' to pedestrians

Evolutionary autonomous S-Class explores empathy with humans

Some researchers in the field of autonomous cars call it "the handshake" — that's the process of figuring out how pedestrians and human drivers will interact with driverless vehicles on the roads. Research has revealed that pedestrians don't feel comfortable when sharing space with autonomous cars, but Mercedes-Benz  says its research shows humans feel better when such cars are clearly marked. Going several steps beyond merely marking a car, Mercedes used an S500 to create a "Co-Operative Car" fitted with sensors, lights, and directional speakers that can communicate with people on the sidewalk and in the road.

The carmaker put four semi-circular pods with turquoise LEDs on the roof, and turquoise LED light bars at the top of the windshield and backlight. Even the light strips on the side mirrors flash in turquoise. Mercedes chose turquoise because it doesn't appear anywhere else in the transportation sphere. The brand would like to see this color become the standard for car-to-pedestrian communication. Two directional speakers fill the corner intakes on the front bumper. The exhibition model should do especially well in the U.S. Northeast, since Daimler's graphic designers unintentionally created a remarkable likeness of the New England Patriots logo on the flanks.

When small portions of the light bars illuminate, the Co-Operative Car is in autonomous mode. Sensors can not only detect people around the car, they can detect faces. The LEDs in this case become analogous to pupils, making 'eye contact' with and tracking pedestrians. For instance, the front lights could let someone at a crosswalk know she's been seen, then use a programmed display to make clear that she's fine to cross. When the Co-Operative Car realizes a pedestrian isn't paying attention, the car can use its speakers to produce "a subtle audio nudge." Or the lights could track a man approaching the car from behind and pulsate in a different programmed display to let him know if the vehicle is moving or plans to move.

The technology demonstrator was shown to media during another of Daimler's FutureInsight talks, this one focused on programming empathetic communication into self-driving vehicles and signaling vehicle intent. This would be an experimental evolution of the autonomous S-Class sedans Daimler and Bosch are using for real-world research in Stuttgart, Germany right now and San Jose, California next year. It's also another take on the matter, compared to Jaguar's application of large cartoonish eyes on an autonomous pod that serve the same purpose. The Co-Operative car is the latest advance on ideas broached with the Mercedes-Benz F 015 concept from 2015, and the Smart Vision EQ ForTwo concept from last year.

And because no story like this is complete without invoking SkyNet, Daimler futurologist Alexander Mankowsky said, "The discussions about the basics [among manufacturers] have already begun," and that we could begin to see results in a few years. He added, "Machine learning has no 'ah ha' moment. There is only training."
