Description

Apparatus and Method for Coverting Driving Control Right in Autonomous Driving The present invention relates to a control switching technology for an autonomous vehicle, and more specifically, to an autonomous driving control switching device and method for switching control of an autonomous vehicle based on driver behavior type information. Generally, autonomous driving technology exists from Level 0 to Level 5. Currently, commercially available autonomous driving technology is at Levels 2 to 2.5, where the vehicle system performs autonomous driving functions partially. The driver must focus on the driving situation and remain ready to drive at any time. Levels 3 and 4 represent stages where the vehicle system takes the lead in driving. Driver intervention is required in dangerous situations or when the situation is not registered with the system. Today's automotive industry is moving toward implementing autonomous driving that minimizes driver intervention in vehicle operation. However, research on technologies to grant vehicle control to the driver under specific conditions or to reclaim control granted to the driver while driving at autonomous driving levels 3 and 4 is lacking. Therefore, as the level of autonomous driving technology advances, there is a growing need for technologies that enable autonomous vehicles to proactively detect external or internal situational information and change control.
