Abstract
According to the disclosure, the steering control device and method may enhance the driver's steering feeling by correcting the steering torque due to a difference in linear distance despite a difference in the linear distance from the rotation axis according to the position of the pressure applied to the steering wheel shaped so that the linear distance from the rotation axis increases/decreases.
Claims18
A steering control device, comprising:
- a steering wheel shaped to increase/decrease in a linear distance to a rotation axis;
- a pressure sensor provided in the steering wheel to detect a pressure applied to the steering wheel;
- and
- a controller determining a grip position based on the pressure applied to the steering wheel detected by the pressure sensor, calculating a steering torque correction coefficient based on a variable linear distance from the rotation axis of the steering wheel to the determined grip position, correcting a steering torque based on the steering torque correction coefficient to calculate a final steering torque, and controlling an output of a motor based on the final steering torque, wherein the steering torque correction coefficient is calculated to be inversely proportional to the variable linear distance from the rotation axis of the steering wheel to the determined grip position.
