The Paravan story

Roland Arnold & Paravan GmbH

Roland Arnold, the founder and managing director of Paravan GmbH, lost his father in a tragic accident when he was a young boy. Since this life-changing event, he has wanted to help people in need. As an adult, he struggled to make a living with a small tyre business and earned a little extra money by operating a combine harvester.

Paravan GmbH is born

The turning point in Roland Arnold’s life came in 1997 at a dreary car park on a motorway: In the pouring rain, he helped a woman who was having difficulties lifting her paraplegic husband into a car. This spontaneous action eventually led to the creation of PARAVAN. Roland Arnold’s vision was to give back mobility and a zest for life to people with disabilities. In a garage on his brother’s farm, he began working obsessively on innovative customised vehicles for disabled people. At first his efforts were greeted with ridicule and scepticism, but this soon gave way to extensive admiration.

The development of Space Drive

Arnold quickly turned his attention to developing a revolutionary drive-by-wire system (which was to become Space Drive) in order to make it possible for people with severe disabilities to become mobile again – or for the first time. His business and social commitment was driven by typical Swabian industriousness and virtually boundless ingenuity and inventiveness. In 2003, he acquired his first patents – and the components for the first generation of Space Drive were soon rolling off the line in his home factory. Paravan GmbH was then established in 2005. For his new company, Arnold built an ultra-modern 50,000 m² mobility park with his own money in Pfronstetten-Aichelau, a community with 270 inhabitants in the German state of Baden-Württemberg.

Paravan has been the global market and quality leader for highly customised vehicles for disabled people since 2009. Today we can make use of a vibrant network of experts in the fields of medicine, research, technology, business and politics. Each day, we learn something new from our customers. We now have 180 employees as well as branch offices and partners all over the world. One thing remains the same, however: the satisfaction that comes from being able to do something useful.

1 billion km travelled

One of the highlights of our extensive product range is the multi-redundant Space Drive II system – the first street-legal drive-by-wire system in the world. This fail-safe digital control system is designed for flexible use in safety-relevant automotive applications with state-of-the-art drive-by-wire technology. Over the last 15 years, Paravan has accumulated more than 1 billion kilometres of experience around the world with its Space Drive drive-by-wire system.

Autonomous driving with Space Drive

Today, Paravan is utilising this wealth of experience to help renowned car manufacturers and automotive suppliers put autonomous and partially autonomous experimental vehicles, prototypes and functional models on the road safely with a multi-redundant drive-by-wire system.

Here unrivalled solutions and vehicles are made. So that people with disabilities can regain their independence.

Milestones in a history of success


Roland Arnold establishes a one-man tyre and minor body-construction business in a garage measuring 4 x 4 metres on his parent’s farm. With no means of financing or support, the trained automotive mechanic struggles through the first few years of his business operations. To make ends meet, he operates a combine harvester wherever he can during the harvest season.

An important event leads to an idea: Roland Arnold helps a woman lift her paraplegic husband into a car in the pouring rain at a motorway rest stop. At that moment, he realises how important it is to create disability-friendly vehicles that allow people to move their wheelchairs directly up to the steering wheel: The idea that would become Paravan is born.

SAM Car project: Is it really possible to drive a Corvette ZR06 simply by moving one’s head? Sam Schmidt, a former Indy-car driver who became a paraplegic after a severe accident during a race, says it is – and ultramodern technology from the USA and Germany makes it possible. In a partnership project conducted by the US electronics experts at Arrow Industries and the Swabian drive-by-wire specialists at Paravan, a Corvette ZR06 is modified and rebuilt to allow Sam Schmidt to control the 650-hp racing car safely around a racetrack by means of the most subtle head movements.

The vehicle is driven at the Indianapolis 500 by Sam Schmidt – who ends up setting a new speed record with it. Another highlight is Schmidt’s performance at the Pikes Peak International Hill Climb, which is one of the toughest auto races in the world.

From a vision to reality. Roland Arnold recognised early on that the automotive industry was set to undergo a transformation, which is why he decided to focus on creating the “automobile of the future” by further developing his drive-by-wire system. The elimination of the mechanical steering column makes it possible to completely redesign vehicle interiors. Roland Arnold understands that automated driving systems, whether in passenger cars, buses, trucks, tractors, etc., are on their way.

Paravan und Schaeffler gründen ein gemeinsames Joint Venture


Schaeffler Technologies AG & Co. KG and Paravan owner Roland Arnold establish the Schaeffler Paravan Technologie GmbH & Co. KG joint venture on 12 September 2018. The key technology for autonomous driving – the Space Drive system developed by Paravan – is fully incorporated into the joint venture, which then begins to further develop and manufacture the system on an industrial scale.


In year ten of wheelchair production - PARAVAN develops two new innovative electric wheelchairs. The PR 40 and PR 25 models are specially designed with and for the needs of customers. Behind the PR 40 is a multifunctional electric wheelchair with standing, lying, sitting and tilting functions, as well as a new standard biometric sliding backrest, for neurological care as well as muscular dystrophies and all para and quadriplegics, but also suitable for stroke patients. With the PR 25 the user can comfortably descend to the floor. For some people, this is the only way to get into the wheelchair independently, to reach things on the floor or to meet playmates at eye level. The extremely flexible PR25 is particularly suitable for children, small adults and people with dysmelia.


Rennwagen der Firma Schaeffler Paravan Technologie GmbH & Co. KG Audi R8 LMS GT3


In order to prepare Space Drive optimally for development for series production, Schaeffler Paravan Technologie has been testing the system under the toughest racing conditions. The Audi R8 LMS GT3 manages without any mechanical connection between the steering gear and steering column and is controlled exclusively by a feedback steering unit via electrical signals. The car is the first in the history of motor racing to have a racing licence from the German Motor Sport Association (DMSB) and is entered in the GTC-Race racing series, formerly DMV GTC. The knowledge gained there flows directly into the ongoing development process and thus also directly benefits the solutions in the field of mobility for the disabled.


First Steer-by-Wire race car at the ADAC TOTAL 24h race at the Nürburgring: PORSCHE Cayman 718 GT4 with Space Drive successfully through the "Green Hell"!
