An automatic software configuring system includes a database storage section for storing therein a plurality of soft components. In the event that soft components are extracted from the database storage section and are combined together to thereby generate a file, a comment indicative of a storage location in the database storage section for storing a respective soft component extracted from the database storage section is added to the respective soft component. The automatic software configuring system further includes a device for identifying the respective soft component combined into the file and a storage location of the respective soft component by reading the comment; a device for identifying a comparison-target soft component stored in the database storage section; a device for identifying a soft component having a different content; and a device for replacing specified soft component in the database storage section with the soft component combined into the file.

An exhaust gas diagnosis system and a vehicle control system for automotive vehicles to reduce the communication lines and the power lines connected to the antiweatherability-required exhaust gas sensor arranged on the exterior of the vehicle are disclosed. The exhaust gas diagnosis system is configured of an engine control unit (electronic control unit), radio terminal units having the sensor function to detect the exhaust gas, and a radio communication repeater to conduct communication and share a part of the process executed by the conventional engine control unit. The communication lines between the sensor and the electronic control unit and the power lines to the sensor required in the conventional systems are eliminated while at the same time reducing the load on the electronic control unit.

A vehicle control system which can ensure high reliability, real-time processing, and expandability with a simplified ECU configuration and a low cost by backing up an error through coordination in the entire system without increasing a degree of redundancy of individual controllers beyond the least necessary level. The vehicle control system comprises a sensor controller for taking in sensor signals indicating a status variable of a vehicle and an operation amount applied from a driver, a command controller for generating a control target value based on the sensor signals taken in by the sensor controller, and an actuator controller for receiving the control target value from the command controller and operating an actuator to control the vehicle, those three controller being interconnected via a network. The actuator controller includes a control target value generating unit for generating a control target value based on the sensor signals taken in by the sensor controller and received by the actuator controller via the network when the control target value generated by the command controller is abnormal, and controls the actuator in accordance with the control target value generated by the control target value generating unit.

The invention relates to a software maintenance supporting device that analyzes and displays the structure of software, and its object is to divide software into clusters including plural variables and illustrate the result of the division. The software maintenance supporting device extracts variable dependence relation data from a source code, and divides software into clusters including plural variables, using a variable dependence relation. Also, an inter-variable dependence relation is illustrated as a directed graph in which a variable is expressed as a node and a dependence relation is expressed as a link, and variables belonging to the same cluster are highlighted.

A device and method automatically generate a program for buffering differences based on characteristics of a component. A buffer program for buffering differences of the way to use a component during different software environments is automatically generated. The device includes a controller for executing automatic generation of the buffer program, a memory including control information and a processing program, an input device for inputting the processing content of the component, and an output device for outputting the automatically generated buffer program. The memory records a plurality of forms for buffering the component as the control information and the controller extracts characteristic information based on the processing content of the component and records the extracted characteristic information as control information in the memory, selects a specified form based on the characteristic information, and generates the buffer program based on the selected form and the characteristic information.
摘要:
To easily specify a difference part among multiple source codes even in the case of software that is relatively large scaled and complicated as an embedded system, and to make it possible for an area of influence that the difference part has to be easily understood. In a software analysis system of an embedded system into which a computer system is embedded, the software analysis system has a similarity measurement part that treats a dependence relationship in the source code controlling the embedded system as a graphical structure and measures a similarity of one or more source codes, and an image display unit for displaying the similarity.

There is provided an embedded control device having high real time performance and capable of securing data concurrency. The embedded control device according to the present invention includes disclosure data and stored data as control data to be disclosed to a data reference component. The embedded control device changes over a reference destination for the data reference component either to the disclosure data or to the stored data, depending on which of the execution priority of the data disclosing source component and the execution priority of the data reference component is higher.
