A software query information management system is configured to associate a required device specification with a regulation ID of a regulation defining a requirement for receiving legal approval for a vehicle and store the required device specification in association with the regulation ID, identify the regulation ID associated with the required device specification associated with traceability information of the device associated with the required device specification, generate software query information in which the identified regulation ID is associated with one or more software IDs included in the traceability information, identify, based on the software query information, a software ID of other software associated with the regulation ID associated with a software ID of software embedded in the device in which an event has occurred, and generate evidence based on communication data of the device having embedded therein the software with the identified software ID.

A fault reproduction assist system that assists a fault reproduction of an abnormal vehicle includes a configuration information acquisition unit that acquires, based on configuration information that is received from the abnormal vehicle and that includes hardware information of hardware in which an abnormality is detected and vehicle configuration information stored in advance in a storage unit, configuration information including the same hardware information as the hardware information of the abnormal vehicle; a configuration information determination unit that acquires from the storage unit software that includes the same software information as software information included in the configuration information acquired by the configuration information acquisition unit, and a distribution unit that distributes the software acquired by the configuration information determination unit to a fault reproduction environment for reproducing a fault.

A CPU forced stop signal is used as means for stopping execution of a program executed on a ROM by a CPU of a target system. A time required for stopping the CPU from the issuance of the CPU forced stop signal between an ICE device and the CPU is considered and set, and a CPU forced stop signal issuance position which is prior to a stop target position is determined. Based on a real-time tracing function of the CPU, at an issuance position and timing of the CPU forced stop signal on the execution of the program, the CPU forced stop signal is issued, the CPU is stopped, and the event is acquired. By this means, an arbitrary number of events of the program can be acquired regardless of the number of breakpoint registers.
