摘要:
A vehicle control apparatus having plural micro controllers interconnected by serial communication realizes data referencing between the microcontrollers without increasing the load on the CPUs and enables the development of control application software easily. The vehicle control apparatus includes plural processing units (1a,1b) each having a computing means (10a), a data storage means (11a), and a communication means (15a). Each of the plural processing units (1a,1b) has a data update monitoring means (13a) which monitors access to the data storage means (11a), acquires, upon detecting update of data in the data storage means (11a), the updated data and a corresponding address, transfers the data and address to the communication means (15a), and starts transmission to another one or more of the plural processing units (1a,1b).

A likelihood indicating the distribution of the frequency of use of each specification of the existing device is calculated for each version of a software component used in the control software of the existing device, and a prior probability indicating the distribution of the frequency of use of each version is calculated for each software component used in the control software of the existing device. A posterior probability indicating the reusability of each version of the existing software component is calculated for each specification of a device to be developed, on the basis of the likelihood and the prior probability.

An automatic software configuring system (100) includes a database storage section (150) for storing therein a plurality of soft components. In the event that soft components are extracted from the database storage section (150) and are combined together to thereby generate a file, a comment indicative of a storage location in the database storage section (150) for storing a respective soft component extracted from the database storage section (150) is added to the respective soft component. The automatic software configuring system (100) further includes a device (121) for identifying the respective soft component combined into the file and a storage location of the respective soft component in the database storage section (150) by reading the comment; a device (123) for identifying a comparison-target soft component stored in the database storage section (150) for comparison with the respective soft component combined into the file in accordance with the storage location; a device (124) 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.
