Abstract:
An automobile control system comprising:a control target mounted on an automobile; and an information processing unit including a memory unit, the information processing unit being for performing arithmetic process for controlling the control target, storing control data calculated in the arithmetic process in the memory unit, subjecting the stored control data to a predetermined process and transmitting the processed control data to a communication opponent, wherein the information processing unit includes at least one of an accuracy conversion unit subjecting a physical value of the control data to be transmitted among the stored data to an accuracy conversion process to produce converted data to be transmitted to the communication opponent, the accuracy conversion process converting the control data having a first resolution to the converted data having a second resolution, and a packet data generation unit for rearranging the control data among the stored data to generate a packet data to be communicated to the communication opponent, wherein the accuracy conversion unit includes conversion program storage means storing a plurality of types of conversion programs for subjecting the control data to the accuracy conversion process, conversion information memory means storing conversion information that defines a correlative relation between each of the control data and each of the conversion programs, and data conversion means for converting the control data to the converted data by specifying one of the conversion programs stored in correspondence with the second data based on the stored conversion information, and wherein the packet data generation means includes a first table storing information of the control data used to generate each of the packet data, a second table storing position information of each of the control data in each of the packet data, and determination means for determining the control data to be used to generate the packet data and the position of the control data to be used in the packet data by referring to the first table and the second table.
