Vehicle control device

A vehicle control device that includes a processor, a storage device including a first storage, and a second storage, and stores a route information for a route of a vehicle to a target point, the vehicle control device comprising:

• an input device that acquires the route information of the vehicle and a surrounding environment information around the vehicle, the surrounding environment information comprising an object information and a road surface information around the route of the vehicle;
• a short-term storage information circuit that stores the route information and the surrounding environment information acquired while the vehicle is traveling into the first storage as short-term storage information;
• a long-term storage information circuit that decides long-term storage information to be stored into the second storage from among the short-term storage information stored in the first storage unit and stores the long-term storage information into the second storage, the decision based upon a calculation by the long-term storage information circuit of a guidance route for automatic drive or automatic parking from the route information and the surrounding environment information;
• and
• a vehicle control circuit that generates guidance route information from the long-term storage information stored in the second storage and controls the vehicle based on the guidance route information,
• wherein the short-term storage information circuit
• calculates a feature degree of the surrounding environment information when storing the route information, the calculated feature degree based upon indices of the object information, the indices of the object information comprising an invariance indicating a probability of an identified object existing at a time of a next travel of the vehicle, and
• extracts and temporarily stores a portion of the surrounding environment information in which the feature degree is equal to or greater than a predetermined value into the first storage as the short-term storage information, and
• wherein a data size of the surrounding environment information to be stored in the short-term storage is reduced based upon the predetermined value of the feature degree of the surrounding environment information.
