The Paravan Space Drive System

Drive-by-wire in a new dimension of mobility
Were you forced to give up driving due to a severe physical limitation or disability? Space Drive II can make your dream of becoming mobile again come true. Space Drive II is a system that is unrivalled anywhere in the world – a real breakthrough. It allows you to drive a car if you have a disability – even with low residual strength, partial paralysis and minimum movement capabilities, and even if you have no limbs. With Space Drive II, you control the brake, accelerator, and steering wheel safely and with absolute precision using driving aids controlled by microprocessors.

No compromises with safety
Patented, TÜV-approved (Section 19 StVZO)
Uncompromising quality and safety
System can be completely deactivated – i.e. assistants can also operate the vehicle “normally” with the steering wheel and the acceleration and brake pedals
Precise and easy operation – a totally new driving experience
All components are manufactured in accordance with the highest automotive industry standards
Fits into all cars
20 million kilometres driven in continual load test (hydro pulses) under extreme conditions
Perfect individual adaptation, even in the case of progressive changes to medical conditions
Multiple redundant safety with two safety systems running in parallel. Full engine power if the control circuit fails
Exact computer configuration of parameters
Safe speed-dependent steering – even at high speeds
Ergonomically relaxed driving

The Paravan Space Drive system – trailblazing mobility for people with disabilities
You always drive safely with the joystick-controlled Space Drive system from Paravan. Background information:

Signals from the input devices are transmitted digitally in milliseconds to a servo motor that controls acceleration and braking, and to an additional servo motor for the steering system (drive-by-wire / steer-by-wire). We configure each module separately in accordance with the specific medical condition in question. The entire system is multi-redundant (triple redundancy), which means that three control circuits that are completely independent of one another constantly operate in parallel and also monitor each other, ensuring absolutely fail-safe operation. Powerful processors and newly developed servo motors guarantee easy and highly precise handling of the vehicle. If your medical condition changes, we adapt the hardware and software components for you accordingly.

Paravan Space Drive technology meets the most stringent requirements as defined in the ISO 26262 safety standard (ASIL D) and is also approved for road use in accordance with ECE-R-10, ECE-R-13 and ECE-R-79. In addition, our drive-by-wire control units are manufactured in accordance with IPC-A-600 class 3, which is the highest quality standard worldwide for such equipment.

It goes without saying that our entire company and all of its business processes are also certified in accordance with the DIN EN ISO 9001:2008 quality-management standard.
