Are you a professional driver looking to maximize your potential on simulator training, or a professional eSports Sim Racer where every hundredth of seconds counts? If so, welcome to the future! Simucube 2 Ultimate Direct Drive force feedback wheelbase puts you in the absolute lead position through its unmatched personalization of force feedback characteristics and unparalleled responsiveness.
Abundant 32 Nm of torque and maxed-out torque response rate is at your disposal at any time. Ultimate is based on Austrian made maximally dynamic industrial motor optimized for simulation. It is equipped with a 24-bit resolution Hiperface angle sensor to be fully utilized by the most advanced signal processing unit seen in simulators.
This model was designed with “only the best is good enough” mindset. Simucube Ultimate is our tribute to the Ultimate drivers.
Reaction time is everything when it comes to overtaking opponents or taking corrective action to prevent loss of tire grip. Simulator’s ultra-low latency not only keeps the driver a step ahead but naturally also removes barriers between the simulated world and the driver. There is no latency in the real world – and in the perfect simulation neither. We, humans, are naturally built to perform optimally in such world.
By coupling a wheel directly to an extremely fast responding direct drive torque motor, Driver will open a straight portal into the physics of the simulated race car and track. Such an ideal torque transducer adds nothing of its own to be felt – it’s just a pure connection to the road behind the wheel. Direct drive is the only known method to achieve sub-millisecond latency and real-life race car dynamic range – the keys to true transparency.
Sensing the tiniest changes in the tire grip at the same time with the high steering force of a sharp corner will transmit the forces of every part of the race car to the driver is the way it works in the real world. The high dynamic range of force feedback equals maximizing the flow of physical information from the simulator to the driver. The greatest need to precisely sense the emerging loss of grip happens to be at the peak force moment. Being able to sense that enables the driver to utilize 100% of the race car potential.
By passing the simulator’s sometimes coarse digitally sampled force commands through force reconstruction engine, the driver will be able to feel the force feedback it was intended by the simulator’s physics engine. Moreover, the real nature modeling based inertia, damping and friction effects calculated right inside the simulator hardware will make the driver feel like they’re connected to the real world – not to a simulator.
The body of Simucube 2 has been built from precision machined solid metal parts. It’s pretty hard to find a plastic part in it – pretty much the only non-metallic one is the “radiofrequency window” for Wireless Wheel Receiver.
Simucube 2 Ultimate has undoubtedly the most accurate angle sensors in all force feedback wheels ever. The sensor has a Hiperface interface with a resolution of 16 million counts per revolution. The quality of the angle sensor information has paramount importance when calculating natural physics effects and filters. Any imperfection of the sensor signal would feel like a distortion in reality. All Simucube 2’s signal processing units have been optimized to take full advantage of the unmatched sensor precision. The output of the Hiperface sensor is sampled at a constant 20 kHz sample rate.
Only the very best is good enough for Ultimate drivers. Simucube developer team compared over 40 motors, hand-tested over ten of them, then picked the best imaginable motor, and finally customized it to suit absolutely flawlessly in professional racing simulation. This is how the Ultimate motor was born. SC2 Ultimate’s motor is designed to operate up to whopping 70 Nm peak torque, so running it up to 32 Nm dynamic range is a breeze. Ultimate motors are also individually calibrated in production to iron out any measurable torque error and ripple.
No Simucube driver shall ever become the victim of interference prone USB connection. Thanks to a galvanic isolation layer between the USB and power electronics. This also protects the PC from current spikes. In addition, all connectors found on the back of SC2 are ESD protected exceeding the industrial requirements.
Dual CPU architecture
To unleash the full potential of the glorious motor and to process signals at maximum precision, Simucube 2 has been given a dedicated 216 MHz real-time processor in addition to a dedicated 144 MHz PC USB interface CPU. Unique dual CPU architecture ensures zero impact on ultra-low latency performance even when all processing and simulator actions are running simultaneously. The new 216 MHz processor features superscalar ARM architecture, making it effectively four times faster than the 72 MHz processors of IONI drive in Simucube 1.
Thanks to high-efficiency direct-drive operation optimized motors and clever electronics heat guiding, there is no dust collecting nor noisy fans in Simucube 2. High-efficiency motor puts out less heat and consumes less power.
All Simucube 2’s electronics have been designed in Finland by Granite Devices – also known from their reliable industrial motor drives. Simucube has been proudly built with the same uncompromising industrial quality principles. This means prioritizing ruggedness and longevity over the cost of the components. Simucube 2 power MOSFETs are rated over 2X their actual need to make them virtually immortal.
Because high torque may pose a hazard if the simulator software goes nuts, or if the driver becomes careless with the high torque wheel, Simucube 2 Ultimate comes with externally mountable premium full-metal Torque off button with a remote power switch.
Becoming a master of multiple race car classes is finally reality without a single compromise. Different kinds of wheels are rapidly and securely interchangeable thanks to solid-metal Quick Release and low-latency Wireless Wheel connection.
Precision machined full-metal Simucube Quick Release guarantees zero-backlash and rock-solid operation even under the extreme torques of direct drive wheelbase. Guided rail design ensures perfect lock-in every time, and the spring preloaded pin mechanism will ensure non-degrading tight coupling over thousands of swap cycles. Just like the rest of Simucube, SQR has been built to be virtually immortal. The only theoretically wearing part, spring-loaded pin mechanism, is made out of standard stock parts making it user-serviceable.
The built-in wireless wheel receiver in Simucube 2 automatically connects to your Simucube Wireless Wheel just by briefly pressing both paddle shifters simultaneously. The wireless wheel transmission protocol has been specially engineered to provide consistent and unbreakable millisecond range response times, as well as an extremely long battery life of over 5 years. Swapping of the wheel will also take effect immediately without the need of re-assigning controls in the simulator.
By passing the simulator’s sometimes coarse digitally sampled force commands through Simucube’s world-famous force reconstruction engine, the driver will be able to feel the force feedback like it was intended by the simulator’s physics engine.
Limits the rate of change in motor torque measured in Newton-meters per millisecond. May be used to adapt sharpness to the fast torque spikes to driver’s preference. The maximum settable slew rate depends on the DD motor (see the comparison table for details).
In addition to simulator controlled damping, inertia and friction effects, Simucube 2 implements real-time physics modeling based user-controllable versions of them. Thanks to a high precision angle sensor in all Simucube 2 modes, these feel practically indistinguishable from real physical phenomena.
Simucube 2 Ultimate adds more detailed tuning parameters to many of the listed signal processing methods and filters. Adjustable parameters include defining the frequency bandwidth of the signal processing allowing drivers to fine-tune the ultimate optimum setting for their rig and simulator. Ultimate drivers also have access to early access features and filters from SC developer team.
