Communication between pedestrians and autonomous cars

D ie communication between man and machine is not really new. A lamp on the oven signals that the target temperature has been reached, a red light on the CRT TV indicated that it was in stand-by mode. People, who now receive every new message on their smartphone with sound signals, used to have their Blackberry always flash red and vibrate when an e-mail arrived.

Allow me to make this excursus to show that you are yourself Will get used to signals and signs that people will encounter in future road traffic.

If a pedestrian or cyclist encounters an autonomously driving car, eye contact with the driver is no longer necessary. The passengers in the vehicle may be busy with a virtual reality application or entertainment. So the car has to communicate with its surroundings. While the digital path is used for communication between the robocars, optical signals should also prevail here for contact with people.

International communication standard

Jaguar Land Rover
The bar fan indicates that the car is about to turn right.

LED lettering on the front of the vehicle has already been shown, but sometimes cannot penetrate a language barrier or is not immediately registered by pedestrians who stare at the display of their smartphone. Jaguar Land Rover has now introduced a new, internationally understandable system for communication between humans and self-driving cars.

A projection of bars on the road shows what the vehicle's plan is. In this way the distances between the bars can be made variable. When braking, they become closer and closer, as if a virtual carpet is pushing together. When accelerating, enlargethe distances accordingly. The direction of travel when turning can be displayed by a corresponding fanning of the bars.

Test run in Coventry

Jaguar is performing practical testing of the optical signals with the autonomous pods from the manufacturer Aurrigo that have already been presented a specially built road in the Coventry area. The self-driving boxes already received artificial eyes last year for direct eye contact and the associated relationship of trust between car and pedestrian In the test series, we want to find out how extensively autonomous vehicles have to share information with pedestrians in order for them to gain their trust. As with any new technology, this is preceded by a learning process. With regard to autonomous vehicles, pedestrians should be safe, for example, to be able to cross a street safely. This basic research forms the basis for ongoing developments on the question of how intensively autonomous vehicles will interact with people in the future. ”
