Steering torque compensating apparatus and steering torque compensating method

摘要

The present invention relates to a technology of compensating for steering torque. More particularly, the present invention provides a steering torque compensating apparatus including: a reference object recognition unit that recognizes a fixed reference object arranged in correspondence to a lane of a road by using a camera of a vehicle; a distance measurement unit that measures a distance difference between the vehicle and the fixed reference object; and an operation determination unit that calculates a distance change rate that is a change rate of the distance difference per time and determines whether the vehicle is driven forwards or rearwards, by using the distance change rate, and a steering torque compensating method.

主权项

1. A steering torque compensating apparatus, comprising:
a reference object recognition unit that recognizes a fixed reference object arranged in correspondence to a lane of a road by using a camera of a vehicle; a distance measurement unit that measures a distance difference between the vehicle and the fixed reference object; an operation determination unit that calculates a distance change rate that is a change rate of the distance difference per time and determines whether the vehicle is driven forwards or rearwards, by using the distance change rate; and a controller that controls an assistance steering torque, wherein the controller
sets the assistance steering torque to a target torque when it is determined that the vehicle is driven forwards,sets magnitude of the assistance steering torque to magnitude of the target torque, andsets a direction of the assistance steering torque to a direction opposite to the direction of the target torque when it is determined that the vehicle is driven rearwards.
