How do you integrate and tune a steer-by-wire system for natural steering feel?

Steer-by-wire integration requires: Defining steering feel targets through extensive benchmarking and driver clinics, developing force feedback algorithms that recreate road feel, self-centering, and friction sensations without mechanical connection, designing fault-tolerant architecture with redundant motors, sensors, and ECUs, implementing latency compensation for responsive feel (target <10ms), tuning torque gradient and damping across the speed range, adding features like variable ratio and active steering, and extensive validation including failure mode testing. Regulatory requirements mandate mechanical backup or demonstrated fail-operational capability.
