Steer-by-wire system with spring-to-center steering wheel control of a vehicle based on lateral acceleration and/or road wheel actuator force

A steer-by-wire system comprising:

• interface circuitry to:
• obtain a measured road wheel actuator force value;
• and
• obtain a steering wheel torque value corresponding to torque produced via a spring-to-center steering wheel;
• machine-readable instructions;
• and
• at least one processor circuit to be programmed by the machine-readable instructions to:
• determine a target road wheel actuator force value based on the steering wheel torque value;
• determine a road wheel actuator force difference between the measured road wheel actuator force value and the target road wheel actuator force value;
• determine a steering pinion angle value based on the road wheel actuator force difference;
• and
• control a road wheel actuator to turn a road wheel based on the steering pinion angle value.

At least one non-transitory machine-readable medium comprising machine-readable instructions to cause at least one processor circuit to at least:

• determine a target lateral acceleration value based on a steering wheel torque value, the steering wheel torque value corresponding to torque applied to a spring-to-center steering wheel;
• determine a lateral acceleration difference between a measured lateral acceleration value of a vehicle and the target lateral acceleration value;
• determine a steering pinion angle value based on the lateral acceleration difference;
• and
• control a road wheel actuator to turn a road wheel based on the steering pinion angle value.
