摘要:
Product line type development is supported by analyzing inter-feature dependency relations based on the use state of feature in existing products and uses the analysis result.Inter-feature linking means 15 analyses the inter-feature dependency relations in the existing products based on a product-feature related information database 14. A related information management unit 16 compares the analysis result of the inter-feature dependency relations to existing information stored in an inter-feature related information database 17, and outputs the result to an interface unit 18 and the inter-feature related information database. A developer can easily consult the analysis result.

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.

There is provided means enabling effective selection of a method of combining software assets in the development of software that is hierarchized and segmented into components. Control software 101 created with a control software development tool 102 includes an application 103 which executes a control calculation process, a connection layer 104 which connects software components with each other, and basic software 114. In conventional software configurations, combination of software components hierarchized in the basic software is described by a standard I/F 108, and thus it has been difficult to flexibly change the method of combining software components adapting to the design change of the software. In the present invention, flexible selection of the method of combining software components is made possible by using template description for the method of combining software components.

摘要:
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.
摘要:
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 in the database storage section by reading the comment; a device for identifying a comparison-target soft component stored in the database storage section for comparison with the respective soft component combined into the file in accordance with the storage location; a device for identifying a soft component having a different content by comparing the respective soft component combined into the file and the comparison-target soft component; and a device for replacing specified soft component in the database storage section with the soft component combined into the file.
摘要:
A vehicle antenna device includes a first antenna and a second antenna. The first antenna surrounds an ignition key cylinder having a key insertion hole and is configured to receive a first signal transmitted from a first transmitter in a key insertion state where a key is inserted into the key insertion hole. The second antenna is configured to receive a second signal transmitted from a second transmitter. The first antenna is positioned between the first transmitter and the second antenna in the key insertion state.
摘要:
For registering or updating the information of second identification codes stored in a theft prevention apparatus when the theft prevention apparatus is replaced, a third identification code sent from a third apparatus which is mounted in a motor vehicle is checked against a third identification code stored in the theft prevention apparatus, and must be identical thereto. Even if a third party prepares and installs an ignition key and a theft prevention apparatus of its own on the motor vehicle, the third identification code is not verified, and hence the information of second identification codes cannot be equalized.
摘要:
A radio control system for controlling a vehicle includes a transmission node for transmitting vehicle control data, the vehicle control data including at least one of a measured value of a vehicle state or a driver's manipulated variable and a control target value of a control actuator in the vehicle, a reception node for receiving the vehicle control data, and a plurality of radio communication routes between the transmission node and the reception node. A radio communication route that satisfies communication limit time of transmission data including the vehicle control data and satisfies lowest required reliability of the transmission data is selected from among the radio communication routes.
摘要:
A data communication system uses an SPI bus having a plurality of devices wherein data communications are enabled using communication protocols optimum to respective devices. The system includes a master device connected to a plurality of slave devices via a data transmission bus by which the master device transfers data to the slave devices, or a data reception bus by which the master device receives data from the slave devices, in a synchronism with a synchronous clock signal. Chip select signal lines also connect the master device to the slave devices, on a one to one basis. Communication drivers set a physical protocol of each slave device, and a communication manager arbitrates serial communications between the master device and the slave devices by their proper physical protocols. Communication protocols such as baud rates, clock polarities, and clock phases are switched by asserted Chip Select signal lines.
