Abstract: A situation recognizer calculates situation recognition information on a peripheral situation of a vehicle based on sensor information indicating the vehicle's periphery, map information, and motion information indicating the vehicle's state; an experience information database including information on each function, a function achievement value indicating each function's achievement degree, and a road on which each function was executed, in association with the situation recognition information, the experience information reflecting an execution result of each function during automatic driving; a control route calculator extracts experience information corresponding to the situation recognition information from the experience information database and calculates a control route including the road where the function achievement value is high; a control determination unit which generates control method information for controlling the vehicle to execute the function on the control route; and a control executor executes the automatic driving based on the control method information.

Abstract: An autonomous driving assistance apparatus includes: a status recognition unit that outputs status recognition information, including status information about a status of a vehicle and a peripheral status of the vehicle; a manual control unit that outputs operation information by manual operation; an experience information database that stores the status information belonging to the status recognition information and experience information about a control method for the vehicle to travel along a route by associating the status information with the experience information; an experience information registration unit that manages the experience information database; an experience information search unit that extracts the experience information corresponding to a search key from the experience information database by using the status information as the search key; and a control judgment unit that: judges whether autonomous driving traveling is possible or not, based on the experience information extracted by the experience information search unit.
