A New Design of Human-Machine Interaction for Steering Articulated Truck Combinations

The main reason for accidents involving trucks or truck combinations is the lack of situation awareness. Drivers of particularly articulated truck combinations need a high level of awareness about the state of the vehicle combination and its surroundings. The current steering interface sets limits on the signals that the driver can perceive and the way the driver can act. I see an opportunity to break these limits on the interaction by introducing a new steering interface. The new interface is intuitive and designed specially for articulated truck combinations. The interface consists of two physical walls on the left and right side of the driver, an active touch panel in front of the driver, and air vibration generators on the left and right side. The driver controls the lateral position of the truck by controlling the position of the walls. The idea is that the driver can easily associate the lateral position of the truck between the lane boundaries with the position of his or her own body between the walls. Further, the driver perceives a map of the surroundings by feeling and following surfaces on the active touch panel. Moving surfaces on the active touch panel represent the truck, trailers, road boundaries, and other traffic users. Important information about upcoming traffic is given through air vibrations that are sent by the air vibration generators towards the driver’s hand. The new interface is designed for highly automated driving, where automation allows the truck to follow a lane at a certain speed. The driver still actively participates in the control of the vehicle, and is always in direct control of the walls. Physical prototypes of the walls and the touch panel have also helped to imagine what the new driving experience would be like. In particular, simple tests have been performed with the prototype of the walls in a real truck on a test track.
