DRIVER ASSISTANCE DEVICE

A driver assistance device includes an image analysis part that analyzes a captured image obtained by capturing a face of a driver of a vehicle, and an abnormality determination processing part that determines whether a state of the driver is in an abnormal state on the basis of an analysis result of the captured image, and performs an emergency driving stop process of causing the vehicle to perform automatic braking if the driver's state is determined to be in the abnormal state. The abnormality determination processing part does not perform the emergency driving stop process when the level of recognition of the face of the image analysis part is lower than the predetermined level.
