Application: Control system and action generation method (Patent ID: US20230418251A1)
The patent filed by Hitachi Ltd. describes a control system for generating actions to control a device based on sensor data received from the surrounding environment. The system includes modules for self-recognition, target action prediction, and switching to determine the appropriate action for the device. The self-recognition module predicts a self-range related to predictability and controllability, while the target action prediction module forecasts the device's action. The switching module then selects between self-recognition and target action to generate the device's action, ensuring adaptability to uncertain environments.
The patent also outlines specific claims related to the control system, including the ability to predict changes in a target object's shape and motion, select self-recognition based on block size and execution time, and generate actions to increase precision or guide a person without interference. The system updates prediction models based on sensor data and includes an action generation method executed by a calculation device and storage device. Overall, the patent focuses on enhancing control system adaptability by integrating self-recognition, target action prediction, and intelligent switching mechanisms to generate appropriate actions for the controlled device in uncertain environments.
