Abstract: The present invention addresses the problem of efficiently moving a plurality of moving objects under different rule-based control systems without impairing safety. In order to solve this problem, a moving body task estimation unit 501 estimates moving body tasks 541 of a plurality of moving bodies 1 under different rule-based control systems, an optimum route generation unit 503 searches for optimum routes 542 using various combinations of a plurality of pieces of task information, and a common movement route creation unit 504 creates a common movement route 543 for the plurality of moving bodies by overlapping the obtained optimum routes 542.

Abstract: The purpose of the present invention is to provide a vehicle control system that can achieve highly comfortable autonomous driving according to the behavior of an occupant by changing a control mode of the autonomous driving according to the behavior of the occupant. To this end, a vehicle control system, which automatically drives a vehicle, comprises: an occupant information detection unit that detects, on the basis of in-vehicle information, position information and behavior information on the occupant; a tolerance calculation unit that calculates a vehicle motion tolerance on the basis of the position information and the behavior information detected by the occupant information detection unit; a trajectory generation unit that generates, on the basis of the vehicle motion tolerance calculated by the tolerance calculation unit, trajectory information including a traveling-scheduled route and time; and an autonomous driving control unit that generates, according to the trajectory information generated by the trajectory generation unit, a control command value to be sent to an actuator of the vehicle.

Abstract: The present disclosure provides a behavior assistance device which improves the autonomy and skill level of a person in question and assists in the behavior of the person in question, so as to prevent a degradation in overall efficiency even when the assistance for the behavior of the person in question is no longer available. A behavior assistance device, which assists in the behavior of a person in question according to the surrounding environment of the person in question, comprises a learning unit, a prediction unit, and a behavior assistance unit. The learning unit learns environmental information pertaining to the environment and behavioral information pertaining to the behavior of the person in question for the environment, and generates a behavior model of the person in question. The prediction unit generates a prediction behavior of the person in question on the basis of the behavior model and the environmental information. The behavior assistance unit generates behavior assistance information for the person in question according to a matching degree between an optimal behavior of the person in question based on the environmental information and the prediction behavior of the person in question.

Abstract: Provided is a mobile body control system capable of improving both the comfort of passengers in each mobile body and the efficiency of cargo transport when a plurality of mobile bodies travel in a formation. A mobile body control system (1) causes a plurality of mobile bodies (21) to travel in a formation along a preset travel route, and comprises a preceding/succeeding acceleration calculation unit (S49) that calculates a preceding/succeeding acceleration of a preceding mobile body (21_n) and a succeeding mobile body (21_n+1) on the travel route. The preceding/succeeding acceleration calculation unit adjusts a gain E of an arithmetic expression used to calculate the preceding/succeeding acceleration on the basis of information about a transported object being transported by each mobile body (21).
