SimForce relies on a high-performance DSP card inside the host PC for communications of up to 1000 Hz. The DSP controls a servo disk type motor which has high bandwidth, low inertia, no gearing, zero cogging and zero backlash. The motor is driven by a powerful 600W servo amplifier, providing high torque and safe speeds. The dedicated DSP processor, executing with a 2000 Hz loop time, provides tight control and dedicated safety. In addition, the DSP’s DX/DT velocity calculation provides smooth feedback. When coupled with Realtime Technologies’ SimVehicleLT, power steer boost curves and tire aligning torque are accurately modeled and presented to the driver.
