Abstract

The invention discloses a method for controlling cornering of a vehicle and an apparatus thereof. According to one embodiment, the method is characterized by including the steps of obtaining surrounding events and spiral loop information within a pre-specified preview distance; selecting a preview point on the basis of changes of curvature of a curved path when the curved path is known within the preview distance according to an obtained result; reflecting the selected preview point and determining a control point; setting the limit speed of a vehicle according to the transverse acceleration and yaw rate of the vehicle when the curved path is known; and determining an acceleration control time point according to a pre-set motion formula and the limit speed after the limit speed is set.

Description

technical field [0001] The present invention relates to vehicle turning control, and more specifically, a vehicle turning control method and device thereof capable of improving curve traveling performance when the vehicle is driven by an autonomous traveling system. Background technique [0002] Generally, vehicles are equipped with various systems to protect the driver and passengers, assist operation, and improve ride quality. [0003] Among the various systems, the autonomous driving system is a technology that uses cameras to recognize lanes and perform automatic steering. [0004] The autonomous driving system uses MDPS (motor driven power steering, electric power steering), ESC, EMS, and TCU as actuators, GPS is installed to grasp the position of the vehicle, and LiDAR is installed to analyze the surrounding environment and the driving of surrounding vehicles ( Lidar), front and rear radar, front camera, ultrasonic sensor, etc., combined with car navigation, ITS (inte...
