The automotive industry is facing one of the biggest upheavals in its history. New drive systems and autonomous driving are much discussed. In this context, the vehicle as a means of transportation will have to be rethought. But what do these developments mean for mobility for the disabled? Boundless freedom or new restrictions?
At some point, autonomous driving will become established in individual transportation and could thus open up further opportunities for people with disabilities. An important key role will be played by drive-by-wire systems such as Space Drive, which at PARAVAN GmbH have already been helping many people with significant mobility impairments to achieve independent mobility for a good 20 years, thus offering quality of life. This change can already be felt in the PARAVAN production halls. More vehicles with alternative drive systems are in demand. Customer demand for assistance systems that already reduce the hurdle to independent mobility or for autonomous driving functions is also increasing noticeably.
Mobility for All Thanks to Autonomous Driving?
Today, existing assistance systems can already offer significantly more options for people with disabilities, combined with a significant increase in safety: be it adaptive cruise control, lane departure warning or digital comfort steering with up to 8 N. In some cases, automatic parking and unparking or vehicle control via smartphone are no longer visions of the future.
If vehicles are perhaps already equipped with a standard dive-by-wire system in a few years, this will make it easier, for example, to integrate customizable control devices such as joysticks or accelerator-brake sliders. More cost-effective solutions could also ensure mobility into old age for a larger group of people - such as retirees, for whom a conversion is no longer financially viable without a cost carrier. Digital accelerator-brake systems also offer greater safety compared to mechanical handheld devices.
Level 4 and 5 autonomous driving could also give more people with a handicap access to independent mobility. But there are a number of hurdles to overcome before this can happen. The most fundamental question, will new vehicle concepts be designed to be inclusive bw. barrier-free from the outset? A basic prerequisite for this is, for example, a central control unit in the car that monitors autonomous driving functions - even in Level 3 or 4 - for example, whether the driver has his hands on the individual input device so that he can intervene in an emergency.
This is both a challenge and an important task for vehicle developers, because future input devices for handicap applications will also have to be continuously developed to communicate with the assistance systems in the vehicle, for example to provide hands on detection - reliable monitoring of functions. For example, under current General Safety regulations, an emergency steering assistant will be mandatory on new vehicle types from 2024. All these developments would offer additional safety.
Under these conditions, fully autonomous vehicles could enable people with disabilities to be mobile in the future, for whom this is not yet possible today due to their medical condition, also through new - inclusive - interior concepts.
Despite the many advantages, the idea of fully autonomous driving, of relinquishing control of the vehicle, is still something of a utopia for many, and hardly imaginable. "I certainly expect that my next car - planned for 10 years from now - will be at least partially autonomous, if not fully autonomous," says Janis McDavid. He was born without arms or legs and has relied on Space Drive and a four-way joystick to equip his vehicles for more than 10 years. "One of the more exciting questions for me from today's perspective is, do I want to give up my autonomy completely to my vehicle? Would that mean, okay, I'm still driving for the first hour, but when I no longer feel like or have the energy to drive myself, I can say, so, car, now take over and drive me to my destination."
New mobility concepts such as fully autonomous people movers could give many more people access to self-determined mobility. Also, not everyone would have to buy their own vehicle. But the vision is still a long way off. To realize it, future vehicle concepts need to be thought of inclusively right from the development stage. Questions like these would have to be considered during development: How can a blind person enter an autonomous vehicle? How will the wheelchair be secured, especially in view of the variety of wheelchair types, and how will this be controlled? Or what happens in the event of a medical emergency? FACT is, further individual assistance systems must be developed for this area of application. An autonomous vehicle alone will not be the solution in this case.
The vehicle industry is facing a disruptive change, in vehicle design and in the area of individual mobility. In order to be able to design mobility in a fundamentally barrier-free and sustainable way in the future, it will require the joint efforts of everyone: car manufacturers, vehicle retrofitters, research institutions, technical departments, health organizations, politicians and the users themselves. Otherwise, at least for the handicap sector, there is a risk of losing more than we gain.
