Description

Autonomous driving control switching notification device and method The present invention relates to a control transfer notification device and method, and more specifically, to an autonomous driving control transfer notification device and method. Autonomous driving technology enables a vehicle to perceive its surroundings and drive without driver intervention. As autonomous driving technology advances, drivers can perform various actions other than driving while on the move. However, since fully autonomous driving has not yet been realized, a transfer of control while driving is required. In such cases, if the driver is engrossed in activities other than driving, it may be difficult to perceive the transfer of control. To address these issues, it is necessary to provide customized notifications based on the driver's condition and situation.
