Abstract

The invention provides a driveway maintenance control device and a driveway maintenance control method. Through use of lane information obtained from a front camera, information obtained from a sensor mounted on a vehicle and information obtained from a car navigator, driveway maintenance of vehicles can be supported. The driveway maintenance control device is characterized by comprising a road curvature computing part, and the curvature of a curve road ahead of the vehicle can be computed through use of the information obtained from the front camera and information obtained from the car navigator; the driveway maintenance control device also comprises a center deviation computing part, a target trajectory computing part and a target steering torque computing part; the center deviation computing part is used for computing center deviation of the curve road on the basis of the curvature, the target trajectory computing part is used for computing a target trajectory of the curve road on the basis of the center deviation, and the target steering torque computing part is used for computing object steering torque on the basis of the target trajectory.

Description

technical field [0001] The invention relates to a lane keeping control device and method. More specifically, a lane keeping control device and method based on route information obtained from a car navigator. Background technique [0002] The traditional LKAS (Lane Keeping Assist System-Lane Keeping Assist System) control method calculates the distance between the lane and the vehicle through the lane information obtained by the imaging device installed on the vehicle, and uses the vehicle's progress obtained through the CAN data of the vehicle. Calculate the lane departure speed based on the direction and speed of the vehicle, and issue a lane departure warning or perform steering control according to whether the vehicle has left or not. [0003] However, this traditional control method only calculates the control amount through the departure distance and the angle between the ego vehicle and the lane, that is, the departure angle. A slight departure angle will also exceed ...
