AI Technical Summary
⚠Technical Problem
Existing steering systems fail to accurately detect and prevent freezing or seizing of steering mechanisms, leading to increased steering effort and potential loss of control, particularly in adverse weather conditions.
⚗Method used
A steering control device and method that includes a predictive determination process to detect sticking and slipping abnormalities in the steering mechanism by analyzing the relationship between drive torque and steering angle, using a control device to apply vibration torque to break ice and prevent freezing.
🎯Benefits of technology
Accurately detects and prevents freezing or seizing of steering mechanisms by applying vibration torque to melt ice and reduce solidification, ensuring reliable steering control.

Abstract
A steering control device according to the present invention is configured to perform a sign determination process and a response process. The sign determination process includes a sticking determination process and a slip determination process. The sticking determination process is a process for determining the occurrence of sticking on the basis of the fact that the absolute value of the rotation amount of a steering mechanism is not more than a prescribed value even when the absolute value of the drive torque, which is a torque for driving the steering mechanism, is not less than a prescribed value. The slip determination process is a process for determining the occurrence of slip on the condition that the logical AND of the fact that the absolute value of the drive torque decreases after sticking is determined to have occurred and the fact that the rotation of the steering mechanism when the absolute value decreases matches the drive torque when sticking is determined to have occurred is true.
