Xiaomi Auto Technology Co., Ltd. has successfully obtained the invention patent authorization for its innovative "force feedback method, device, vehicle, and medium tailored for steer-by-wire systems." This pioneering approach entails capturing the steering wheel's rotational speed, angle, and the vehicle's speed. Initially, it discerns the rotation direction by analyzing the steering wheel's rotational speed and integrates this information with the angle to formulate the foundational force. Subsequently, it calculates a primary ratio that is inversely related to the vehicle's speed, thereby determining the initial feedback torque. This meticulous process culminates in precise force feedback on the steering wheel, offering drivers a consistent and robust hand-force feedback experience, enhancing overall driving stability and control.
