摘要： PROBLEM TO BE SOLVED: To optimize a code applicable to a built-in control system without increasing a necessary memory capacity.
SOLUTION: A total control part 110 reads out a model diagram and an operation diagram of software specifications stored in a storage unit 104, and starts up a specification analysis part 106 to conduct word and phrase analysis and grammar analysis. An object oriented function rejecting part 107 is started up thereafter to determine a function not used, based on a function selection item stored in the storage unit 104. Then, a code generation part 108 is started up to generate the code based on the software specification phrase-analyzed and grammar-analyzed in the specification analysis part 106, and based on an output code pattern determined in the object oriented function rejecting part 107.

摘要： PROBLEM TO BE SOLVED: To guarantee that the contents of data will not be destroyed through communication software of a version by generating a transmitted message from transmitted data and then transmitted message equivalent data from the transmitted message, and deciding whether the transmitted data match the transmitted message equivalent data corresponding to the transmitted data. SOLUTION: High-reliability communication software 2080 performs a sum process for data in an application program, when sending the data. The sum- processed data are written to a mailbox, and the data written to the mailbox are restored to the original data through a check sum process. Then by confirming that no abnormality is detected, it can be guaranteed that the contents of the sum process and sum-processed data have been written to the mailbox without their being destroyed. Furthermore, it is confirmed that the data to be transmitted the application program 2006 match the data after the check sum process.

摘要： PROBLEM TO BE SOLVED: To attain a controller for an automobile, capable of rewriting the controlling contents of an automobile stored in a storage device through a transmission network, and rewriting the controlling contents after confirming proper operation with the contents. SOLUTION: A changer's permitting function 36 determines whether or not the changing operation from changer's operating terminal 31 is permissible. If the changing operation is permitted, a changing content is transmitted from the changing content recording medium 32 to the changing content permitting function part 35 of an information control center 21 through a transmission network 23a, and whether a changing content is permitted or not is determined. If a changing content is permitted, a testing function part 34 confirms that a control system 22 operates properly after a change in the stored contents. The testing function part 34, after confirming the normal operation of the automotive control system 22, permits the changing content to be stored in storage devices 11c to 11n.

摘要： PROBLEM TO BE SOLVED: To keep time limitation for real time control even when a delay in communication between a transmission node an a reception node or a delay in execution of a task in a node takes place. SOLUTION: Sensor input information 301 and an execution result of a task 201 executed based on the input information in a transmission node 102 are sent to a transmission line 103. A reception node 104 receives the sensor input information 301, executes a task 1043 of the same content as the task 201 based on the input information and an output selection section 202 selects either of the execution result of the task 1043 and the execution result of the received task 201 as actuator output information 302. Since the execution result keeping a time limit is selected and outputted among the task execution results executed by plural nodes, the probability of keeping time limitation for real time control is improved.
