  • Publication number: 20210046949
    Abstract: The automated driving system automatically drives a vehicle by cooperative operation of a travel control device controlling travel of the vehicle and a portable device possessed by a driver of the vehicle. In the cooperative operation, the portable device transmits route data to the travel control device; the travel control device sets an event location on the route, based on the route data, controls travel of the vehicle in an automated-driving control area, based on the route data and circumstance data, and transmits notification data for notifying the driver of a change of a travel condition to the portable device; and the portable device notifies the driver of the change, based on the notification data. Upon receiving an operational input to stop the cooperative operation, the portable device notifies the driver of a warning message or ignores the received operational input if the event location is set in the area.
