Consciousness state determination system and autonomous driving apparatus

An autonomous driving apparatus which is mounted on a vehicle and executes an autonomous driving control of autonomously carrying out driving maneuverings of the vehicle,

• the autonomous driving apparatus comprising:
• an image-taking section which takes images of a driver of the vehicle;
• and
• an electronic control unit which executes a consciousness state determination process of determining whether the driver is conscious, based on a driver image corresponding to the image of the driver taken by the image-taking section while the electronic control unit executes the autonomous driving control,
• wherein the electronic control unit is configured to determine whether the driver is conscious, based on terminal-side information corresponding to information acquired from a mobile terminal when a predetermined condition that a reliability level of a determination result obtained from the consciousness state determination process is presumably low, becomes satisfied.
