Achieving a positive user experience through user-friendly design of the vehicle interior for automated driving functions
No radical changes to vehicle interior design or the basic concepts of driver-vehicle interaction have occurred in many decades. But, with fully automated driving (SAE level 4), the driver is no longer responsible for the task of driving the vehicle, and this will lead to a change in the needs of users.
The purpose of the RUMBA project is to completely redesign the vehicle interior and ride experience for the occupants when the vehicle is in fully automated driving mode.
The research project has set itself the goal of breaking away from established, conventional ways of thinking about interior design. Within the scope of RUMBA, the researchers aim not only to redesign the entire interior HMI concept but also to develop a new kind of vehicle control concept based on steer-by-wire, which combines acceleration, deceleration, and steering control in a single element.
In addition, the automated vehicle’s trajectory planning will be specifically optimized to cater to the vehicle occupants’ feeling of safety and comfort. To reach the project goals, a user-centered development process is being used that comprises three iterations in which the demonstrator maturity, user group, and evaluation environment (test bench, test track, real traffic) differ. This ensures that the changed user requirements with respect to ergonomics, sense of space, ambience, ride comfort, occupant comfort, wellbeing, controllability, and confidence in the system are optimally modeled in the prototypes.
The influencing factors and cause-effect relationships are mapped for the passenger car and commercial vehicle segments together in a joint requirements and solution space for interiors that takes all disciplines into consideration. This makes it possible to apply the concepts to both of these vehicle segments. The aim of the project is to gain a comprehensive understanding of user requirements for fully automated driving, to develop solution concepts, and to have prototypes evaluated by end users. On the basis of these activities, it will then be possible to provide recommended courses of action for successfully driving forward the development of fully automated driving.
