ople and the HMI of the Future The driver’s workplace in the car has been at the core of automobility since it began over a hundred years ago: starting with an unpretentious focus on essentials, made complex with an abundance of switches around the turn of the millenium, and culminating in the tidy looking ensemble of large screens in today’s cockpits. IAV illustrates the pressure for change in design of user experience, user interface and HMI.

WHAT IS CREATING THE PRESSURE TO CHANGE TODAY’S HMI?
ATZ worldwide 11|2020
The digitization has fundamentally changed consumers’ expectations of their mobility experience. It is creating ever-increasing pressure to change the Human-machine Interface (HMI) of a car. As a result of ever more extensive driver assistance systems, the classic driving task is becoming easier and less demanding; at the same time, drivers are looking for ways to repurpose their time behind the steering wheel: to do some work, to relax, to be entertained, to communicate – or to enjoy a treasured moment of solitude?

IAV’s insights from numerous customer projects show that an “ ideal” traveling experience even within the same vehicle should probably look a little different for each occupant. As a result, the HMI of future vehicles would have to present itself differently to each user. However, this individualization is not explicitly asked-for by the user. Ra ther, it is identified and executed by a constant analysis of the activity context. IS THE HMI FUNCTION GROWING BEYOND THE DRIVER’S PLACE?
For a long time, HMI development focused on designing the driver’s workplace. Today’s vehicles still have the technical character of “connected cars,” that means, they are stand-alone products to which connectivity capabilities have been added, late in the lifecycle. Now, however, E/E vehicle architecture is starting to change: It is being transitioned toward an Internet of Things (IoT) platform with a redundantly designed, maximum-security domain for safety- relevant f unctions and a well-protected second domain for comfort and thirdparty functions. At the end of this multi-step process, future vehicles will have been transformed into “rolling devices on the IoT,” that means, they will have a digital DNA from the outset. As a consequence, vehicles will become yet a further device in the portfolio of every user. U
