STEER-BY-WIRE SYSTEM WITH SELF-CENTERING STEERING WHEEL CONTROL OF A VEHICLE BASED ON lateral acceleration and / or wheel actuator force

Abstract

Disclosed exemplary steer-by-wire systems include an interface circuit to: obtain a measured lateral acceleration value of a vehicle; and obtain a steering wheel torque value corresponding to a torque generated via a self-centering steering wheel; machine-readable instructions; and at least one processor circuit to be programmed by the machine-readable instructions to: determine a target lateral acceleration value based on the steering wheel torque value; determine a lateral acceleration difference between the measured lateral acceleration value and the target lateral acceleration value; determine a steering pinion angle value based on the lateral acceleration difference; and control a wheel actuator to turn a wheel based on the steering pinion angle value.
