In spite of a severe degree of paraplegia, a former US Indy-car pilot is back behind the wheel of a racing car modified by Paravan and Arrow Electronics. New speed record at the Indy 500.
Is it really possible to drive a Corvette ZR06 simply by moving one’s head? Sam Schmidt, a former Indycar driver who became a paraplegic when he had a severe accident during a race, says yes you can. Ultramodern technology from the USA and Germany makes it possible. In a cooperative project by the US electronics experts at Arrow Industries and the Swabian drive-by-wire specialists at Paravan, a Corvette ZR06 is converted and reconstructed so that Sam Schmidt can control the 650-HP racing car safely around a racetrack by means of minute head movements.
How does that work? Multiple camera sensors in the cockpit and infrared measuring points on Schmidt’s head digitalize each movement of the head to the left or right and pass the data on to a control center integrated by Arrow, a so-called motion-tracking system. The signals are processed together with the car data by means of special software and passed on the Paravan Space-Drive II head module. This second CPU then sends the signals to steering motors with multiple redundancy which carry out the corresponding steering commands. Acceleration and braking take place by means of a specially developed mouthpiece with an integrated pressure sensor. This sensor registers whether Schmidt sucks in air via the mouthpiece (braking takes place), or blows air through it (similar to a whistle) – causing the vehicle to accelerate. The changes in pressure are also sent to the CPUs, recalculated and then sent to servomotors on the accelerator and brakes via the Space Drive head module.
To ensure that even at speeds beyond 200 km/h nothing happens, the Paravan system is certified in compliance with the strictest world-wide safety standard: ISO 26262 ASIL D. Paravan takes no risks in production and has the system manufactured exclusively according to the most stringent quality standard, IPC 600 A, comparable to the production of a cardiac pacemaker. The goal: 100 per cent reliability.
The sensor technology and its processing have been developed in the US by Arrow. The experts from Aichelau in Swabia install the sensors and connect the Arrow technology to the Paravan drive-andsteering system, Space Drive II.
Meanwhile the Paravan Space Drive technology is used by numerous international vehicle manufacturers as fail-safe and street-legal drive-by-wire platform for autonomous and semi-autonomous driving.
The innovative vehicle celebrated its public premiere last Sunday at this year’s Indy 500 in Indianapolis. The modified vehicle immediately achieved a new speed record of 152 mph (244 km/h) on the Oval. Further show venues are, among others, Detroit Grand Prix (3. - 5. June 2016) and the traditional Pikes Peak International mountain race (23. - 26. June 2016). The vehicle will be coming to Germany in October and November with presentation dates in Hockenheim and the Electronica Fair in Munich.
