Problems solved by technology
Therefore, when determining the degree of yaw in various situations such as normal driving, lane change, and the vehicle at an intersection, there are discontinuities in the yaw value, making the yaw control of the vehicle unnatural
In addition, many branch statements are input when determining the bias value, which increases the complexity of the bias value determination logic, and the bias value cannot reflect the accuracy of the vehicle's position recognition, the risk of nearby vehicles and the driver's driving style
[0007] Especially in the case of determining the deviation value based on the degree of lane encroachment, the vehicle cannot react in advance even if another vehicle is predicted to approach in road sections with narrow lane widths

The present invention relates to a biased driving system and a biased driving method using lane and road shape information, which are capable of controlling biased driving of a vehicle in consideration of the location recognition accuracy of the vehicle, the risk of a nearby vehicle, the driving style, the road curvature, and the road shape. The biased driving system includes a control parameter generation unit configured to extract an object causing a vehicle to be biased using fused object information, which is map information including positions and speeds of vehicles around the vehicle, an imaginary line of the extracted object is generated by reflecting at least one of a risk of a nearby vehicle, a position recognition accuracy, a driving style of a driver of the host vehicle, a road curvature, or a road shape, and a control parameter is generated using the imaginary line.
Description
[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims the benefit of Korean Patent Application No. 10-2020-0186460, filed on December 29, 2020, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to a biased driving system and a biased driving method, and more particularly, to a method that utilizes lane and road shape information and is capable of taking into account the accuracy of vehicle position recognition, nearby vehicle risk, driving style, road curvature and road A yaw system and a yaw method for controlling the yaw of the vehicle by shape. Background technique [0004] The autonomous driving of the vehicle requires automatic acceleration and deceleration control technology and steering control technology based on the driving lane. In Korean Patent Application Publication No. 10-2019-0123663 published on Nov. 1, 2019, a traveling path providing device includes a sensor 1...
