STEERING CONTROL DEVICE
First Claim
1. A steering control device comprising:
- a white line detection unit programmed to detect a left or a right white line of a traveling lane;
a white line approach suppression turning amount calculating unit programmed to calculate a white line approach suppression turning amount based on a distance in which a host vehicle is separated from the white line when a host vehicle approaches either the left or right white line;
a turning control unit programmed to suppress a turning unit that turns a turnable wheel based on the white line approach suppression turning amount; and
a limiting unit programmed to limit the white line approach suppression turning amount, upon determining that the other among the left and right white lines is undetectable and a distance between the host vehicle and the left or right white line decreasing, an increase in the white line approach suppression turning amount is inhibited while permitting a decrease in the white line approach suppression turning amount.

Abstract
A steering control device is provided that calculates a white line approach suppression turning amount that is based on a distance between a host vehicle is separated from either a left or a right white line when a host vehicle approaches either a left or a right white line. The steering control device controls a turning unit for turning a turnable wheel based on the white line approach suppression turning amount, and upon determining that the other among the left and right white lines cannot be detected and a distance between the host vehicle and the left or right white line is decreasing, an increase in the white line approach suppression turning amount is inhibited while permitting a decrease in the white line approach suppression turning amount.

5. A steering control device comprising:
-
a controller programmed to calculate a white line approach suppression turning amount based on a distance in which a host vehicle is separated from either a left or a right white line when the host vehicle approaches the left or a right white line; and control a turning unit for turning a turnable wheel based on the white line approach suppression turning amount, and upon determining that the other among the left and right white lines cannot be detected and a distance between the host vehicle and the left or right white line is decreasing, an increase in the white line approach suppression turning amount is inhibited while a decrease in the white line approach suppression turning amount.

6. A steering control device comprising:
-
a sensor for detecting a left or a right white line of a traveling lane; and a controller programmed to calculate a white line approach suppression turning amount that is based on a distance between a host vehicle and the left or a right white line, when the host vehicle approaches either the left or right white lines; and
, the controller being further programmed to control a turning unit for turning a turnable wheel based on the white line approach suppression turning amount, and upon determining that the other among the left and right white lines cannot be detected and a distance between the host vehicle and the left or right white line is decreasing, an increase in the white line approach suppression turning amount is inhibited and a decrease in the white line approach suppression turning amount is permitted.
