Abstract:
1. An electronic control apparatus for a vehicle comprising: an identification information memory device for storing vehicle identification information uniquely assigned to the vehicle; an individual information memory device for storing vehicle individual information related to the vehicle, the vehicle individual information including control information used for control of the vehicle and fault diagnosis information representing a fault diagnosis of a predetermined section of the vehicle; a memory control device for overwriting old vehicle identification information stored in the identification information memory device with new vehicle identification information, the old vehicle identification information being previously written to the identification information memory device and currently stored in the identification information memory device; a clear device for clearing at least the fault diagnosis information of the vehicle individual information from the individual information memory device when the memory control device overwrites the old vehicle identification information; an abnormality determination device for determining whether the old vehicle identification information is abnormal by a checksum method, a mirror data method, or a majority method in response to an overwrite command to overwrite the old vehicle identification information; an equality determination device for determining whether the old vehicle identification information is equal to the new vehicle identification information upon determination of the abnormality determination device that the old vehicle identification information is normal; and a clear control device for performing a clear control, the clear control enabling the clear device to clear both the control information and the fault diagnosis information of the vehicle individual information upon determination of the equality determination device that the old vehicle identification information is different than the new vehicle identification information, the clear control disabling the clear device from clearing both the control information and the fault diagnosis information of the vehicle individual information upon determination of the equality determination device that the old vehicle identification information is equal to the new vehicle identification information, wherein the memory control device overwrites the old vehicle identification information upon determination of the abnormality determination device that the old vehicle identification information is abnormal determination of the equality determination device that the old vehicle identification information is different than the new vehicle identification information, the memory control device does not overwrite the old vehicle identification information when the equality determination device determines that the old vehicle identification information is equal to the new vehicle identification information, the clear control device is capable of performing the clear control upon determination of the abnormality determination device that the old vehicle identification information is normal, and the clear control device performs a clear disable control upon determination of the abnormality determination device that the old vehicle identification information is abnormal, the clear disable control disabling the clear device from clearing the control information of the vehicle individual information.
