ARITHMETIC OPERATION SYSTEM FOR VEHICLE

An automotive arithmetic system (SY) includes: a main arithmetic unit (110) that generates a travel route using deep learning based on an output from a vehicle external information acquisition device (M1); an auxiliary arithmetic unit (120) that generates a rule-based travel route in a free space without using deep learning; a safe route generation unit (300) that generates a safe route, which is a route that the motor vehicle takes until the motor vehicle stops at a safe stop position; and an override processing unit (410) that prioritizes one of the travel route generated by the main arithmetic unit (110), the rule-based travel route generated by the auxiliary arithmetic unit (120), or the safe route generated by the safe route generation unit (300), and determines a target motion of the motor vehicle so that the motor vehicle travels on the prioritized route.
