Audi R8LMSGT3 car adopts space transmission line control technology Professor Peter Guzmer: "Racing car is an ideal test ground for the key technology of autopilot. Roland Arnold: "The system works under extreme conditions.

Schaeffler R8LMSGT3, using Schaeffler steering technology, made its debut in the 24-hour endurance race held in Newboardi, Germany, racing at 240 kilometers per hour on the Newboardi track without a steering column. This car uses the space transmission and force feedback steering technology of Scheffler Paravan. There is no mechanical connection between steering wheel and steering device. It is the first wire-controlled steering vehicle approved by the German Motor Sports Federation (DMSB).

RECING provides an ideal test environment for SpaceDrive, enabling us to fully verify the requirements and functions of the system. For future autopilots, the wire control system is an indispensable technology. Testing the system in a racing environment is crucial and necessary for eventual mass production. Professor Peter Guzmer, Deputy Chief Executive Officer and Chief Technical Officer of Schaeffler Group, said.

Very high reaction rate

In the racing environment, this technology is facing extreme testing conditions, which impose strict requirements on the speed and responsiveness of the system, which provides ideal conditions for continuous improvement and optimization of the system. "The reliability of the system can be demonstrated by keeping the ideal route and slowing down the vehicle within one hundredth of a second at 250 kilometers per hour," Nord said.

Schaeffler plans to participate in the Granismo RV competition (DMVGTC) in order to continue the development of this technology. The improved Audi R8LMSGT3 was approved for testing in the final game of the series and performed well on its first appearance. "At the racetrack, drivers react much faster than their daily driving," said Markus Winkelhock after the race. "When the car turns sharply, it must be able to turn left and right in a very short time. "At first I wasn't sure if the system could do that. In fact, the steering response of the vehicle is very fast and accurate.

Space Drive: Foundation for L4 and L5 Self-Driving

The R8 LMS GT3 is equipped with a special force feedback steering wheel. Steering instructions are no longer transmitted mechanically, but are completed in a few nanoseconds by means of electrical impulse through wire harness (i.e. steering by wire control). Space Drive technology has been on the market for 17 years, with more than 1 billion kilometers of public road accident-free driving records. The Space Drive system meets the strictest quality and safety standards and is licensed for road use. This technology uses triple redundancy design: if a steering component fails, there are two spare components to ensure the normal operation of the system, to meet the absolute failure safety requirements. These make Space Drive the key technology to realize L4 and L5 self-driving, and create conditions for creating innovative car interior concepts. Schaeffler expects the system to be used in mass production by about 2021.
