Abstract: The problem of ensuring safety and work efficiency for the actions of a control target is addressed in an environment in which different types of control systems coexist. A safety control server controls the actions of respective control targets in differing systems and includes an action adjustment unit that, for each control target of differing control systems, outputs to a control target an action adjustment instruction for adjusting the action of that control target when a contention occurs in which the action of that control target deviates from an assumed control result. An action plan adjustment unit, when the adjustment of the action satisfies a prescribed condition, adjusts an action plan indicating an action rule for achieving a function and avoiding a contention in a control target; and a safety rule adjustment unit adjusts a safety rule indicating an action rule for avoiding a contention in the control target.

Abstract: In a traffic flow control system, communication is performed with a travel control device of a moving body passing through a transportation route and the traffic flow of the transportation route is controlled. The traffic control system includes an entry authority management unit and a communication unit. In a transportation route divided into virtual areas, the entry authority management unit manages entry authority for each area, managing tokens in a number that corresponds to the area, and guiding entry of the moving body to the area by attaching entry authority to a token and delivering the resulting token to the travel control device. The communication unit communicates the entry authority and tokens to the travel control device.

Abstract: An apparatus and method for controlling a vehicle is proposed. Detection of a traffic light along the trajectory of a cruising vehicle and a determination of current and future traffic light statuses is performed. It is determined whether the vehicle can arrive at the traffic light during a passing status in accordance with an adaptation of the kinematic vehicle state. Signals are provided via a human 10 machine interface corresponding to various kinematic vehicle state adaptation scenarios in order to enable an arrival at the traffic light during a passing status. In response to the respective human machine interface signals, control of the vehicle can be performed accordingly.

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).
