Abstract
The disclosure relates to a vehicle steering control device and method. There may be provided a vehicle steering control device and method that may detect a slip state of the steering wheel according to the driving state when misalignment occurs between the steering angle of the steering wheel and the rotation angle of the steering motor and performs control to release the slip state, thereby securing driving safety.
Claims18
A steering control device of a vehicle, comprising:
- an angle difference calculator calculating an angle difference between a steering angle and a rotation angle based on information about the steering angle of a steering wheel of the vehicle and information about the rotation angle of a steering motor;
- a slip determiner determining whether a slip state occurs in the steering wheel according to the angle difference and a driving state of the vehicle;
- and
- a controller controlling to release the slip state of the steering wheel by rotating a pulley of the steering motor based on a driving speed of the vehicle if the steering wheel is determined to be in the slip state,
- wherein the slip determiner calculates an accrued value of the angle difference if the driving state of the vehicle corresponds to a parking state or a straight driving state, the angle difference is a threshold, and the slip determiner determines, if the accrued value of the angle difference is out of a preset range, that the steering wheel is in the slip state.
