Abstract: A driving assistance device is configured to assist driving of a vehicle having an autonomous driving function. A traffic status acquisition unit is configured to acquire a traffic status in a section between a present location of the vehicle, which drives in automatic operation in an automatic operation feasible section, and an end point of the automatic operation feasible section. The automatic operation feasible section is set as a limited domain in advance on map information. A timing determination unit is configured to alter change request timing, at which a change request is made to request a driver to make a driving change from the autonomous driving function to the driver, according to the traffic status acquired by the traffic status acquisition unit.

Abstract: An HCU, which controls information presentation to a driver of a vehicle with autonomous driving function, is configured to: determine a switch between a monitoring unnecessary state and a monitoring necessary state, the monitoring unnecessary state being a state in which stoppage of periphery monitoring by the driver during execution of the autonomous driving being permitted, the monitoring necessary state being a state in which the stoppage of the periphery monitoring by the driver during execution of the autonomous driving being prohibited; determine whether stoppage of steering wheel grip by the driver is permittable in the monitoring necessary state; and permit, when the monitoring unnecessary state is switched to the monitoring necessary state in which the stoppage of steering wheel grip is permittable, the stoppage of steering wheel grip in the monitoring necessary state after executing a grip request, which requests the driver to grip the steering wheel.
