Description

Technical Field [0001] The present invention relates to a system and method for determining a driving position of a vehicle,

The present invention relates to a system and method for selecting a vehicle traveling position during operation, and more particularly, to a system and a method for automatically controlling a vehicle traveling position when driving on the road in consideration of a driving characteristic of a driver.

Generally, the vehicle is equipped with various systems for driver and passenger protection, driving assistance and ride comfort improvement. Of the various systems for driver convenience, the autonomous drive control system recognizes lanes using a camera and performs automatic steering.

Of the various driver assistance systems (ADAS) for driver convenience, the technique of performing automatic steering through the image sensor occupies a very large proportion. Among them, Lane Departure Warning System (LKAS: Lane Keeping Assist System, LGS: Lane Guide System), which applies image sensor, is the basis of front camera application technology installed in vehicles.

BACKGROUND ART [0002] A technique relating to an autonomous driving that reflects a behavior characteristic of a driver for a route search and a driving operation is disclosed in, for example, JP-A-2001-0022305. The autonomous driving control system according to the related art measures the lane width, the lateral position of the vehicle, the distance to both lanes, the shape of the lane and the radius of curvature of the road based on the image processing of the camera, And road information, and operates the steering apparatus so that the vehicle can maintain or change the lane.

In a typical vehicle, the driver is accustomed to the longitudinal control that is immediately visible to the eye, while the lateral control, which can not immediately recognize which object (e.g., vehicle, obstacle, etc.) is on the side, feels uncomfortable. Furthermore, the lateral position of the vehicle in which the driver feels a sense of security when driving is different for each individual. Some drivers experience a sense of stability when driving in the middle of a lane, and some drivers feel a sense of stability on the right or to the left.

However, in the conventional autonomous drive control technology, when the driving characteristic data of a driver other than the vehicle main driver is obtained when determining the past driving pattern to grasp the characteristics of the driver, or when an unexpected situation occurs during the driving data acquisition, There is a problem in that it is not possible to provide optimal driving control to the driver on board the vehicle.
