Autonomous driving control system and autonomous driving control method

An autonomous driving control system for a vehicle that travels on a road provided with a marker that emits a steady magnetic field or a quasi-steady magnetic field, the autonomous driving control system comprising:

• a magnetic sensor array that is equipped on the vehicle and senses magnetism;
• an information processing circuit that generates an image showing a magnetic field in a region closer to the marker than the magnetic sensor array, according to a sensing result of the magnetism and a fundamental equation of the steady magnetic field and the quasi-steady magnetic field, and controls travel of the vehicle according to the image;
• the marker provided on the road;
• and
• an induction circuit that is equipped on the vehicle and induces a first magnetic field component, wherein
• the marker is an electric conductor that is conductive and emits the steady magnetic field or the quasi-steady magnetic field by inducing a second magnetic field component in response to the first magnetic field component.
