Abstract (en)
[origin: WO2022170050A1] A combined brake and motor providing tactile feedback control to a human-machine interface steering input device as part of a steer-by-wire system is provided. The brake is a tactile feedback device (TFD) brake and the motor is an electric motor coupled to the brake. The brake provides end stop control and resistive torque to the steer-by-wire system. The motor provides motion control to the steer-by-wire system, where motion control includes a return-to-center, a command following, an on-center control, an active force-feel, and/or a warning mode (e.g., similar to an aircraft stick shaker or a lane departure). The steer-by-wire system is an active system.
