Abstract
An information processing method is executed by a processor to control display related to a target route to be traced by an autonomous towing device that tows a trailer by autonomously driving a tractor. The information processing method includes: receiving input of the target route between nodes as waypoints of the autonomous towing device; and displaying a predicted travel area through which the autonomous towing device is predicted to pass, in association with the target route. The predicted travel area is correlated with a trace error of the tractor relative to the target route, and a trace error of the trailer towed by the tractor.
