Abstract

PURPOSE:To judge whether a fault occurs to a CPU or a circuit without requiring any complicated procedure by allowing each control system to transmit normal/abnormal status information on the system and that on another control system. CONSTITUTION:At respective control systems A-D, pieces of their normal/ abnormal status information and pieces of normal/abnormal status information on other systems are stored. To other control systems, pieces of status information on the control systems other than transmission destination systems are transmitted, respectively. The respective control systems A-D judges whether a specific control system is normal or abnormal by using the piece of information transmitted directly from the specific control system and the pieces of status information transmitted from other control systems.
