ARITHMETIC OPERATION SYSTEM FOR VEHICLE

A vehicle arithmetic system includes a single information processing unit (1). The information processing unit (1) includes: a vehicle external environment estimation unit (10) configured to receive outputs from sensors that obtain information of a vehicle external environment, and estimate the vehicle external environment including a road and an obstacle; a route generation unit (30) configured to generate a traveling route of the vehicle which avoids the obstacle estimated on the road estimated, based on an output from the vehicle external environment estimation unit (10); and a target motion determination unit (40) configured to determine a target motion of the vehicle so that the vehicle travels along the traveling route generated by the route generation unit (30).
