Abstract:
1. A vehicle communication system between a device control electric control unit (ECU) and an information memory apparatus comprising: at least one device control ECU mounted on a vehicle and having an electronic controller executing a device control process for controlling a device portion, which drives a predetermined object or obtains information about the predetermined object; and an information memory apparatus mounted on the vehicle and different from the at least one device control ECU, wherein: the electronic controller includes: a variation information memory storing variation information that identifies the predetermined object, which is driven or detected by the device portion; a characteristic information memory storing characteristic information that represents a result of an actual measurement with respect to a characteristic of the device portion; a process execution portion switching a content of the device control process to another content and executing the another content according to the variation information stored in the variation information memory and the characteristic information stored in the characteristic information memory; a vehicle information obtaining portion obtaining vehicle information from the information memory apparatus at a predetermined timing, extracting the variation information from the vehicle information, and controlling the variation information memory to store the variation information, wherein the vehicle information corresponds to a result of merging the variation information of each of the at least one device control ECU and represents a specification of the vehicle; a characteristic information providing portion transmitting the characteristic information from the characteristic information memory to the information memory apparatus when the information memory apparatus requires the characteristic information; and a subsidiary information obtaining portion obtaining the characteristic information from the information memory apparatus and storing the characteristic information to the characteristic information memory when the information memory apparatus requires the characteristic information in a state where the characteristic information memory does not store the characteristic information; and the information memory apparatus includes: a vehicle information memory storing the vehicle information; a vehicle information providing portion transmitting the vehicle information stored in the vehicle information memory to the at least one device control ECU when the at least one device control ECU requires the vehicle information; a subsidiary information memory storing the characteristic information associated with each of the at least one device control ECU; a characteristic information obtaining portion obtaining the characteristic information from the at least one device control ECU and storing the characteristic information to the subsidiary information memory at another predetermined timing; and a subsidiary information providing portion transmitting the characteristic information from the subsidiary information memory to the at least one device control ECU when the at least one device control ECU requires the characteristic information, wherein the characteristic information is transmitted from the at least one device control ECU to the subsidiary information memory and stored in the subsidiary information memory at the another predetermined timing; and the characteristic information is transmitted from the information memory apparatus to the characteristic information memory and stored in the characteristic information memory when the information memory apparatus requires the characteristic information of the characteristic information memory in a state where the characteristic information memory does not store the characteristic information.
