Abstract
An automobile control system has a microcomputer that subjects each control data to be transmitted to a communication opponent to LSB conversion (accuracy conversion) to convert the control data to the data having the resolution acceptable for the communication opponent. The microcomputer stores a plurality of types of LSB conversion programs and a physical value conversion table. The microcomputer activates the physical value conversion program corresponding to the control data to be transmitted this time based on information listed in the table and subjects the control data to LSB conversion process according to the program of the physical value conversion. The microcomputer further has a Handle number specification table and a packet number specification table. The microcomputer generates the packet data to be transmitted based on the two tables. A transmission target packet number is used for regular transmission and the Handle number of the data to be event-transmitted is used for event transmission.
