Description

Autonomous Vehicle and Autonomous Driving Supporting System The present invention relates to an autonomous driving vehicle and an autonomous driving support system, and more specifically, to an autonomous driving vehicle and an autonomous driving support system that detects abnormal driving patterns and provides alarm information. As automotive electronic technology advances, interest in autonomous vehicles is growing, as vehicles can recognize their driving environment and drive to their destination on their own without driver intervention. An autonomous vehicle refers to a vehicle capable of operating on its own without operation by a driver or passengers. While driving in autonomous driving mode, if a vehicle exhibiting abnormal or threatening driving behavior is present nearby, avoidance control is performed; if an abnormality occurs within the vehicle itself, it is recognized as abnormal driving pattern information, and appropriate measures are taken. For example, there are cases where drivers cause major accidents by failing to recognize lane departures due to driving on abnormal road sections, bad weather, or drowsy driving. To address this, the vehicle is equipped with a Lane Departure Warning System (LDWS). This lane departure warning system captures a forward image using a camera mounted on the front of the vehicle and detects the driving lane using an image processing unit, and warns the driver through a buzzer sound or voice guidance when the vehicle deviates from the driving lane. However, while clear abnormal driving such as lane departure is easy to detect, there are cases where the vehicle must be detected as an abnormal driving pattern when driving in a zigzag pattern without leaving the lane, as shown in Fig. 1 (b), similar to the normal driving state as shown in Fig. 1 (a).
