Edge device and distributed system

A distributed system comprising:

• an edge device configured to support control over a drive mechanism provided in an automatically operable moving body;
• a diagnosis cloud server configured to generate learning data based on data received from the edge device;
• and
• a management server configured to generate function update data for the edge device using a result learned based on the learning data generated by the diagnosis cloud server, wherein
• the edge device includes
• a sensor provided in the automatically operable moving body;
• a recognition unit configured to recognize an object based on input data from the sensor;
• a determination unit configured to determine a recognition result of the recognition unit;
• a drive mechanism control unit configured to control the drive mechanism based on a determination result of the determination unit;
• an unexpected event determination unit configured to determine whether an unexpected event has occurred based on information from the recognition unit and the determination unit;
• a data shaping unit, wherein when it is determined that an unexpected event has occurred, the data shaping unit shape, as communication data, a recognition result of the recognition unit, or the input data used for recognition by the recognition unit, and a determination result of the determination unit, or a calculation history up to the determination result;
• a communication unit configured to transmit, to the diagnosis cloud server, the communication data shaped by the data shaping unit;
• a first memory configured to hold a recognition result of the recognition unit and the input data used for recognition by the recognition unit;
• and
• a second memory separate from the first memory, the second memory being configured to hold a determination result of the determination unit and a calculation history up to the determination result, wherein
• when it is determined that an unexpected event has occurred
• the data shaping unit shapes, as communication data, a recognition result of the recognition unit, the input data used for recognition by the recognition unit, a determination result of the determination unit, and a calculation history up to the determination result,
• the unexpected event determination unit issues a trigger signal to the first memory and to the second memory instructing the first memory to hold raw data already contained in the first memory and instructing the second memory to hold data already contained in the second memory without rewriting the raw data already held in the first memory and the data already held in the second memory, and
• after the first memory receives the trigger signal instructing the first memory to hold the raw data already contained in the first memory, the data shaping unit extracts only a part of raw data held in the first memory and shapes the extracted part of the raw data as communication data, and the communication unit transmits the shaped and extracted part of the raw data to the cloud server.
