Abstract
A steering wheel-based HMI system for a vehicle includes a steer-by-wire system and a control module. The steer-by-wire system includes a steering wheel and a torque feedback unit mechanically connected to the steering wheel. The control module is communicatively connected to the torque feedback unit. The control module is configured to identify a communication, gather information about user securement of the steering wheel, and operate the torque feedback unit to apply a supplementary torque to the steering wheel for haptically issuing the communication through the steering wheel. The supplementary torque has a magnitude that is scaled based on the information about user securement of the steering wheel.
