AI Technical Summary
In existing vehicle steering systems, systematic offset of the torque sensor leads to incorrect identification of steering handle contact and release during automated driving, affecting operational safety and functionality.
By identifying the compensation torque related to the systematic offset of the torque sensor during calibration operation, and superimposing it with the torque signal during automated driving operation, the contact of the steering handle is monitored. An oscillating torque is generated using a calculation unit and an actuator unit to determine the value of the compensation torque, which is stored in a numerical table for real-time adjustment.
It improves the operational safety and functionality of vehicles in automated driving operations, prevents incorrect recognition and release of the steering handle, and ensures driver warnings and vehicle safety status.
